“Who desires to live eternally?Freddie Mercury asks sadly concerning the song of the identical name from Queen 1986.

The answer: quite a couple of people – a lot that the life extension has been a household industry for a very long time.

As a health care provider and scholar within the medical humanities, I actually have expanded the seek for the human life span each fascinating and with moral danger.

For example within the Nineteen Seventies and 80s, The Merv Griffin Show Provided that a guest 32 – experts from Life Exension, Durk Pearson, who generated more fan mail than every guest except Elizabeth Taylor. In 1982 he and his partner Sandy Shaw published the book “Life expansion: a practical scientific approach“, Who became a bestseller of the New York Times No. 1 and sold over 2 million copies. A selected advice was to take choline and vitamin B5 to cut back the cognitive decline, to combat hypertension and to cut back the structure of toxic metabolic by -products.

Last yr, Pearson died around 82 years old and Shaw died in 2022 on the age of 79.

Nobody can say with certainty whether these experts for the expansion of life ultimately died once they avoid a lot of these dietary supplements and as an alternative simply practiced and eaten a balanced weight loss plan. But I can say that they didn't out survive many similarly wealthy people of their cohort.

Nevertheless, her dream of staying young eternally is alive and good.

Consider Tech entrepreneur Bryan Johnsons'Project blueprint“A life effort that inspired the 2025 Netflix documentary” “Do not die: the person who desires to live eternally. ““ “His program included the development of a house laboratory, taking greater than 100 pills each day and by blood plasma transfusions, at the least one among his son got here.

And Johnson will not be alone. Among the large names The Amazon founder Jeff Bezos, the Google founder Sergei Brin and the Larry Page, and Larry Ellison von Oracle invest to increase their lives. An approach Includes the intake of senolytics – Medicines that concentrate on cells that may advance the aging process, although more research is crucial to find out their safety and effectiveness. Another human growth hormone that has long been advertised as an anti-aging mechanism in promoting campaigns that contain remarkably older people. (“How does this 69-year-old doctor have the body of a 30-year-old?” Reads an online display).

These billionaires can argue that they need to live greater than abnormal people on account of their assets. You may share more prosaic motivations, just like the fear of old and dying.

But such wishes are based on an equally necessary ethical – and for some spiritual – reality.

Quality versus quantity

Is it morally a superb thing to wish to live eternally? Could there be facets of aging and even death which are each good for the world and good for the person?

Ciceros “Aging”Offers some insights. In fact, the old Roman statesman and philosopher found that writing about it helped him find peace with the anger of old growth.

In the text outlines and reacts to 4 frequent symptoms of aging: it takes away from leading our affairs, impairing the physical strength, sensually satisfying us and getting us to the speed of death.

To the indictment that aging deprives us from the administration of our affairs, Cicero asks us to assume a ship. Only the young climb to the masts, run backwards and forwards on the gangways and provides the hold. But it’s one among the older and more experienced members of the crew to search out the captain who commanded the ship. The Senate of Rome was called the Senate by Latin for “Elder”, and it’s as much as the wealthy in years during which we most frequently seek for wisdom.

With regard to the impairment of physical strength, Cicero, claimed that strength and speed were less related to age than with the discipline. Many older individuals who maintain themselves are in a greater form than the boys, and he gives examples of people that have maintained their strength until their later years. He argued that those that stay physically fit helps quite a bit to keep up their mental powers, an concept that is supported by modern science.

Cicero reminds the readers that the identical joys, when you eat and drink it, often mislead people. Instead, individuals with increasing age can higher appreciate the fun of spirit and character. An excellent dinner is less characterised by what’s on the plate or the attractiveness of a dining partner than the standard of the conversation and community.

While death stays an inevitable consequence of aging, Cicero distinguishes between quality and life. He writes that it is best to live well than to live for a very long time, and for individuals who live well, death appears as natural as birth. Those who wish to live eternally have forgotten their place within the cosmos, which will not be a few single person and even species.

Those of a more spiritual bent could feel interested in the Scottish poet George Macdonald, Who wrote: “Age will not be just the decay; It is the maturation, the swelling of the fresh life inside, which owes and bursts the shell. ”

Hug the circle of life

What if the dreams of the life extension gurus were realized? Would the world be a greater place?

Would the additional good that an extended Einstein might have been achieved, balanced and even exceeded the damage of a Stalin that remained healthy and powerful for a long time?

At some point it might mean less space for individuals who don’t yet exist.

Pearson and Shaw performed in lots of other television programs within the Nineteen Seventies and Nineteen Eighties. During such a segment “” “The Mike Douglas Show“Pearson said:” Until she is 60 years old, your immune function may be a fifth what it was when you were younger. However, you can simply achieve a remarkable restoration by taking nutrients you can take in a pharmacy or health business can get. ”

For Pearson, the life extension was a biomedical challenge that focused more on the strategy of self than on the world.

https://www.youtube.com/watch?v=5SSKLHTFCPQ

Nevertheless, I’d argue that the true challenge in human life now not live, but help others; Adding additional years mustn’t be seen as a goal, but as a by -product of the striving for kindness.

In the Words of Susan B. Anthony: “The older I get, the more power I have to help the world; I am like a snowball – the further I rolled, the more gain. “

I broke his neck.

When I made a vase on the bike of the Potter, I called his slippery neck once I tried to dilute him right into a graceful curve.

I find vases enjoyable and their shapes particularly nice for the attention. However, vases must even be treated with special care, since a part of their “body” – the neck – is usually so narrow that it could be easily broken.

On this present day on the wheel, I noticed that it was not unlike the human neck. Although only a small a part of the human body – About 1% in accordance with surfaces – Our necks have an amazing influence on our psyche and culture.

From selfies to formal portraits, the neck positions the top in expressive poses. Vibrate the vocal cords of the neck to make sensible words and moving songs. We kiss it passionately and inject it with seductive perfume. We use it to nod in the top in agreement, tilt our heads confused and bend our head in prayer.

Ornaments akin to necklaces can express the sense of fashion and the signal of prosperity and standing. Collar can emphasize the face in portraits and describe the skilled class. Blue collar against white collar.

Despite all its aesthetic and expressive effectiveness, the neck can also be a spot of fear and deep vulnerability. Villars and vampires zero on the neck. Stress working days let our neck muscles break until they pain. A pleasing meal could be torn into terror if a bite within the improper tube slips on the neck and sends us right into a coughing.

For millennia, people have suppressed their subjects in power by profiting from the narrow and fragility of the neck – a dark history of dominance and terrorization with bonds and loops and guillotine. The widespread video by George Floyd's murder was a brutal memory This violent suffocation is hardly limited to the distant past.

When I became aware of the importance of neck within the culture, I started to look at how these two properties – its expressive vitality and annoying susceptibility – could possibly be coexisted and so intensively concentrated in a small area of ​​the body. Ultimately, It was a book.

I’m above all a biologistAnd once I wrote my book, I discovered that the vitality and vulnerability of the neck are rooted in its biology: the neck carries out a very number of decisive functions and is the product of a unusual evolutionary history.

The neck does so many things at the identical time. For example, It transports 2,000 kilos (907 kilograms) blood, air and food between the top and upper body day by day. It moves average every six seconds to attract our visual attention. Its vocal cords Vibrate a whole bunch of times per second With every spoken word.

This multifunctionality, this vitality, is just possible due to its susceptibility. To be mobile and versatile, the neck have to be tight and is subsequently barely tense. The decisive transport pipes – the trachea, the esophagus and the blood vessels – must even be thin and shut to the surface, which supplies them barely fitting and compressed.

From water to land

Our ancestors of the vertebrates “invented” this special invention once they developed from water to land.

Our ancestors with fish had no neck because They needed a single rigid axis to maneuver through water efficiently. Since the movement on land didn’t need a stiff spine, early terrestrial vertebrates were developed flexibility directly behind the topAllows you to scan the environment comprehensively and steer your mouth towards prey without moving your whole body. Imagine a zebra that the top -an pages -monitoring of the savannah for predators or a lizard that tends your head down and aside to call up a creeping mistake.

Early land vertie Also developed lungsAnd this transformation filled the gill structures that fish used to breathe as a way to have developed into different useful and sometimes problematic neck structures akin to the voice box, the almond and the small rag that separates the air tube and the esophagus.

This conversion of scrap, that are left of the gills of our distant ancestors, contributed to the varied capacities of our neck. But as products of a unusual evolutionary “renovation”, people and other country live with a design oriented by Jerry that creates us to wear many collateral weaknesses on the neck.

The strange human neck

While the human neck retains the fundamental design of our ancestors, it continues to be quite unusual for vertebrates.

Most agricultural animals increase their bodies on 4 legs in order that their necks should be long enough to scale back their heads on the ground to feed, and powerful enough to extend them up to go searching. Think again of a zebra that feeds on the savannah.

Since people go on two legs, we balance our head on our spine. Since we use our hands to grab our food, we don't need strong neck muscles to maneuver the top around. Compared to most mammals of our size, our neck are relatively weak, which makes it more prone to stress and injuries.

As one other milestone in human evolution, The voice box migrated into a comparatively low position within the neckAnd this unusual placement contributes to our ability to create a very big selection of vocal sounds that we use for the language. However, this descent of the voice box within the throat also makes us more prone to suffocate and sleep apnea.

The neck embodies the double nature of the human condition, the way in which through which beauty and frailing are sometimes intertwined, two sides of the identical coin in our biology, in our relationships – and even in ceramic vases.

My colleagues and me At Purdue University, the human values ​​embedded in AI systems have uncovered a major imbalance. The systems were predominantly geared towards information and usefulness values ​​and fewer for prosocial, well-being and bourgeois values.

In the middle of many AI systems there are large collections of images, text and other data forms used to coach models. While these data records are meticulously curated, it will not be unusual for them to sometimes contain unethical or forbidden content.

To be certain that AI systems don’t use harmful content when response to users, the researchers brought a way called Learn learning from human feedback. Researchers use highly curated data records with human preferences to form the behavior of AI systems with a purpose to be helpful and honest.

In our study, We examined Three open source training data rates utilized by leading US ACI corporations. We have created a taxonomy of human values ​​through a literature research from moral philosophy, value theory and science, technology and social studies. The values ​​are well -being and peace; Information search; Justice, human rights and animal rights; Duty and accountability; Wisdom and knowledge; Courtesy and tolerance; and empathy and helpfulness. We used the taxonomy to comment on a knowledge record manually after which train the annotation for an AI language model.

Our model enabled us to look at the info records of the AI ​​corporations. We found that these data records contained several examples that train the AI ​​systems with a purpose to be helpful and honest if users asked questions corresponding to “How do I book a flight?”? The data records contained very limited examples of how questions on topics about empathy, justice and human rights are answered. Overall, wisdom, knowledge and data search were the 2 commonest values, while justice, human rights and animal rights were the least common value.

Why is it necessary

The imbalance of human values ​​in data records for the training of AI could have a major impact on how AI systems interact with people and tackle complex social problems. If AI is integrated more into sectors, e.g. LawPresent Health care And Social mediaIt is significant that these systems reflect a balanced spectrum of collective values ​​with a purpose to ethically meet people's needs.

This research can also be at a vital time for the federal government and political decision -makers, since society deals with questions on Ki -Governance and ethics. Understanding the values ​​embedded in AI systems is significant to be certain that they serve one of the best interests of humanity.

Which other research is carried out

Many researchers are working on aligning AI systems to human values. The introduction of learning learning through human feedback was groundbreaking Because it offered a approach to lead the AI ​​behavior to be helpful and truthful.

Different corporations develop techniques to forestall harmful behaviors in AI systems. However, our group was the primary to introduce a scientific method for evaluation and understanding which values ​​were actually embedded in these systems about these data records.

What's next

By making the values ​​embedded in these systems, we would really like to assist AI corporations to create more balanced data records that higher reflect the values ​​of the communities they serve. Companies can use our technology to search out out where they don’t cut well after which improve the variability of their AI training data.

The corporations examined by us may not use these versions of your data records, but can still profit from our process to be certain that your systems match social values ​​and norms.

Artists can take over copyright works with the assistance of artificial intelligence, based on a brand new report by the US copyright, which could proceed to make clear the best way for the Use of AI tools In Hollywood, the music industry and other creative areas.

And while lots of these decisions are constituted of case to case Report on Wednesday Clarifies the approach of the office as one based on what the best US copyright describes, described as a “centrality of human creativity” within the creation of a piece that justifies the protection of copyright.

“Where this creativity is expressed by the use of AI systems, it continues to enjoy protection,” says a explanation of the register of copyright Shira Perlmutter who heads the office.

An AI supported work might be protected by copyright if the manual work of an artist is perceptible. A human adaptation of an AI-generated edition with “creative arrangements or modifications” could also drop it under copyright protection.

The report follows a review that began in 2023 and issued opinions from hundreds of people who were enough for AI developers about actors and country singers.

It shows that the copyright office will proceed to reject copyright claims for fully generated content from machines. According to the report, a one that only prompted a chat bot or AI image generator to create a job doesn’t give this person the chance to guard this work too. “Expansion of protection to material, the expressive elements of which are determined by a machine … would undermine the constitutional goals of copyright than to promote,” said Perlmutter.

The debate about copyright -protected human work, which is drawn from the Internet and other sources, isn’t addressed within the report back to train AI systems. Often without permission or compensation. Fine artists, authors, news organizations and others have sued AI company For copyright theft in cases that also work through US dishes.

The copyright office doesn’t burden these legal cases, but it surely is working on one other report that’s working “the training of AI models on copyright -protected work, licensing considerations and allocation of all liability”.

The secretary of the Ministry of Health and Human Services (HHS) plays a very important role within the access of each American for health care and general well -being of the nation.

After leading the secretary, the many agencies that form HHS monitor the financing of Medicare and Medicaid, research to enhance nursing quality, monitoring fraud and abuse of health care and response to pandemics.

I’m a Scholar of Health policy and former fellow by Robert Wood Johnson Health Policy within the US Senate Committee for Health, Education, Labor and Pensions. In my time as a fellow from 2000 to 2001, I saw how significant the role of the HHS secretary in protecting and maintaining the health of our nation.

The instruction of the secretary influences America's ability to organize for health threats, to take up vaccines in childhood, to enhance the water supply and quite a lot of other public health measures. Understanding how the department and its leader influence the health of the United States is especially necessary in the current day of persistent, up -and -coming infectious diseases and misinformation.

What does the secretary do for health and human services?

The secretary for health and human services is a member of the president's advisory cabinet, which is appointed by the President with the recommendation and approval of the US Senate. The secretary advises the president on questions of health policy and measures in the sector of public health and is accountable for 13 operating departments Responsible for the health of the nation.

The charge of the HHS secretary is to watch the Mission of the department: “Improving health and well-being of all Americans, by providing effective health and human services and by promoting the well-behaved, continuing progress in the sciences on which medication, public health and social services are based.”

The implementation of this mission requires considered one of the biggest budget for a US federal authority. According to the Office for Management and Budget, the Department of Health and Human Services has taken under consideration no less than 20% of the federal budget Since the 1995 financial 12 months. For the 2025 financial 12 months, the HHS requested roughly US $ 1.8 trillion US dollars in federal expenditure.

Powers of the HHS secretary

The secretary for health and human services has several necessary powers with which you’ll finance and implement programs and initiatives which can be of crucial importance for American health and well-being.

One of those powers is the best to administer and regulate Medicare, Medicaid and the Affordable Care Act or ACA. Most of the HHS budget goes to Medicare and Medicaid programs that make up 52% and 33% of the fundsrespectively. In coordination with the centers for Medicare and Medicaid services, the secretary defines guidelines for canopy, payment and repair provision. The secretary also issues regulations and guidelines for the implementation of ACA regulations, manages the federal government Health insurance marketMake sure Rights and benefits inside the framework of the ACA.

The HHS secretary also has the supervision of medical and scientific research. Through the National Institutes of Health or NIH, the secretary provides far -reaching power to finance and promote the causes, diagnosis, treatment, control and forestall illnesses. The NIH has an annual budget of greater than 47 billion US dollars.

With the spread of international trips, the country's health increasingly is dependent upon the health of the world. The HHS secretary represents the USA in Global health issuesCooperation with the World Health Organization, Foreign Governments and Health Ministries to enhance the Pandemic willingness and global health security.

Emergencies for public health

The HHS secretary also has the legal authority to organize for public health and medical emergencies and to react.

For example the Law on public healthcare Approves the HHS secretary to steer the federal reactions to health threats, including the reason of an emergency for public health to regulate transferable diseases.

Through the Food and Drug Administration the Federal food, drug and cosmetics law Enables the HHS secretary the safety and effectiveness of food, pharmaceuticals, medical devices and cosmetics.

The secretary may enable the FDA to issue an emergency permit and use clinicians not approved medical products as a way to manage certain conditions in an emergency. For example, the HHS Secretary said in the course of the Covid 19 pandemic that the circumstances justified the FDA to issue a one USA for the Covid 19 vaccinesin order that they might be delivered to the market quickly.

Under the Law on social securityThe secretary is entitled to avoid or change certain requirements for the portability and accountability of Medicare, Medicaid and Health Insurance. This provision ensures that objects and healthcare services can be found for programs as a part of the social security act during public emergencies.

Remarkable HHS secretaries

The management of a health and human service can support and lead health programs, use the insurance expansion and determine how the nation reacts to a pandemic.

For example, Donna Shalala was the longest in office from 1993 to 2001. She created the Children's insurance program In 1997, which expanded the access of the healthcare system for tens of millions of youngsters.

Oveta Culp Hobby was the primary secretary of HHS, which was then called the Ministry of Health, Education and Social Welfare. It served from 1953 to 1955 and directed the rollout of the Polio vaccine During her last 12 months, this led to the virtually extermination of this disability disease within the United States.

Serves from 2009 to 2014, Kathleen Sebelius was significant within the implementation of the Affordable care law. She helped to be founded by the medical insurance market and was committed to the expansion of Medicaid as a part of the ACA, causing tens of millions of Americans with low income to receive medical insurance.

The priorities and decisions of the HHS secretary have a direct and everlasting influence on the health and well-being of most Americans, which makes this role one of the vital necessary within the federal government.

President-elect Donald Trump said Thursday that he’ll nominate vaccine skeptic and conspiracy theorist Robert F. Kennedy Jr. as vaccine secretary Department of Health and Human Services.

If the Senate votes for Kennedy, the previous independent presidential candidate will lead a sprawling department accountable for the enormous medical health insurance programs Medicare and Medicaid, the Food and Drug Administration, the National Institutes of Health and the Centers for Disease Control and Prevention.

HHS spending and policy decisions have significant impacts on the U.S. health care system and its related businesses.

Kennedy, 70, is the son of Robert F. Kennedy, the late U.S. attorney general and Democratic senator from New York who was assassinated by a gunman in Los Angeles in 1968 while running for president. He is the nephew of former President John Kennedy, who was assassinated in 1963.

Trump said in October that if elected, he would let Kennedy “go wild on health care.”

“I am pleased to announce Robert F. Kennedy Jr. as U.S. Secretary of Health and Human Services,” Trump wrote in a post on his website Truth Social on Thursday.

“For too long, Americans have been oppressed by the industrial food complex and pharmaceutical companies that have engaged in deception, misinformation and disinformation when it comes to public health,” Trump wrote.

“The safety and health of all Americans is the most important responsibility of any government, and HHS will play a major role in ensuring everyone is protected from the harmful chemicals, pollutants, pesticides, pharmaceutical products and food additives that have contributed to the overwhelming Health crisis in this country.”

Kennedy thanked Trump in a post on

“We have a generational opportunity to bring together the greatest minds in science, medicine, industry and government to end the chronic disease epidemic,” Kennedy wrote. “I look forward to working with HHS’s more than 80,000 employees to lift the agencies from the oppressive cloud of corporate capture so they can pursue their mission of restoring Americans to the healthiest people in the world.”

Kennedy said in a recent interview with NBC News that Trump said he wanted Kennedy to “clean up the corruption” in federal health agencies, return those agencies to science-based policies and “make America healthy again.” Kennedy said, “There are entire departments, like the FDA's nutrition division, that have to go.”

Vaccine makers' stock prices fell early Thursday on reports that Trump would tap Kennedy for the HHS post.

Kennedy suggested last yr that the Covid-19 virus, which the CDC played a serious role in combating, was engineered to “attack Caucasians and Blacks” and cause less harm to “Ashkenazi Jews and Chinese.”

He previously promoted theories that autism was linked to childhood vaccinations, a link that has been debunked.

Kennedy outraged a lot of his siblings when he endorsed Trump in August after abandoning his long-held presidential bid.

Trump's choice of Kennedy got here a day after the Republican president-elect nominated Florida Rep. Matt Gaetz to be attorney general.

Gaetz's selection immediately sparked controversy, due largely to the proven fact that the Justice Department, which he would lead as attorney general, had previously investigated him for possible sex trafficking of a 17-year-old girl.

Gaetz resigned from Congress effective Thursday, removing himself from the jurisdiction of the House Ethics Committee. But quite a lot of Republican senators have called on that panel to release a report on its investigation into the previous lawmaker.

Kennedy last week allegedly proposed shedding 600 NIH employees and replacing them.

Be “Make America Healthy.”“The website solicited suggestions from the public for more than 4,000 positions Trump would fill across the federal government.

Senate Finance Committee Chairman Ron Wyden, D-Ore., criticized Kennedy in a statement.

“Mr. Kennedy's outlandish views on basic scientific facts are troubling and should concern all parents who expect schools and other public spaces to be safe for their children,” Wyden said.

“When Mr. Kennedy comes before the Finance Committee, it will be very clear what Americans have to lose under Trump and the Republicans in Congress.”

Another Democrat, Sen. Patty Murray of Washington, said: “Donald Trump's choice of a notorious anti-vaxxer to lead HHS couldn't be more dangerous – a cause for grave concern for every American.”

“There is no telling to what extent a fringe conspiracy theorist like RFK Jr. could set America back on public health, reproductive rights, research and innovation, and much more,” Murray said.

Sen. John Thune of South Dakota, who will grow to be Senate majority leader in January when Republicans take control of the chamber, said he had no response to Kennedy being chosen for the HHS post.

“Honestly, the whole nomination process is just starting, so we're giving him a chance to see what happens,” Thune told reporters.

“And none of those names have been formally submitted yet, so there will be a vetting process. I have told people that these will be drafted after consultation and consent and we will make sure we process them there.”

But other Republican senators, including Tommy Tuberville of Alabama, Rand Paul of Kentucky and Josh Hawley of Missouri, also praised Kennedy's choice.

“Bad day for Big Pharma,” Hawley tweeted.

Andrea DukesVice president for health policy on the advocacy group Center for American Progress called Trump's selection of Kennedy “nothing in need of disastrous for the country” in an announcement.

“His track record and open skepticism of long-standing medical science could jeopardize the incredible public health progress we have made as a nation – including the progress we have made in combating infectious diseases through childhood vaccination programs and in securing our food supplies achieved through pasteurization,” said Ducas.

“This election is particularly concerning as it comes on the heels of the COVID-19 pandemic, in which life-saving vaccines prevented countless infections and deaths.”

We made our first rodent automobile out of a plastic cereal container. After trial and error, my colleagues and I discovered that rats could learn to drive forward by grasping a small wire that acted like an accelerator pedal. Soon they were steering with surprising precision to achieve a treat within the Froot Loop.

As expected, rats kept in a designed environment—complete with toys, space, and companions—learned to drive faster than rats in standard cages. This finding supported the concept Complex environments improve neuroplasticity: the power of the brain to alter throughout life in response to environmental demands.

After we published our research, the story of the drifting rats followed went viral within the media. The project continues in my lab with latest, improved rat-powered vehicles, or ROVs, designed by a robotics professor John McManus and his students. These upgraded electric ROVs—with rat-proof wiring, indestructible tires, and ergonomic control levers—resemble a rodent version of Tesla's Cybertruck.

As a neuroscientist who’s committed to it Since we house and test laboratory animals in natural habitats, I discovered it amusing to see how far we deviated from my laboratory practices on this project. Rats typically prefer dirt, sticks, and rocks over plastic items. Now we allow them to drive cars.

But humans didn't evolve to drive cars either. Although our ancient ancestors didn’t have cars, They had flexible brains This allowed them to accumulate latest skills – fire, language, stone tools and agriculture. And a while after the invention of the wheel, people made cars.

Although cars made for rats are removed from the whole lot they encounter within the wild, we thought driving a automobile presented an interesting method to study how rodents acquire latest skills. Unexpectedly, we found that the rats had strong motivation for his or her driving training, often jumping into the automobile and revving the “lever engine” before their vehicle hit the road. Why was that so?

The latest goal of joy

Concepts from introductory psychology textbooks got a brand new, practical dimension in our rodent driving laboratory. Building on fundamental learning approaches comparable to: operant conditioningwhich reinforces goal-directed behavior through strategic incentives, we trained the rats step-by-step of their driving programs.

First, they learned basic movements, comparable to stepping into the automobile and operating a lever. But with practice, these easy actions evolved into more complex behaviors, comparable to steering the automobile to a particular destination.

The rats also taught me something profound one morning through the pandemic.

It was the summer of 2020, a time marked by emotional isolation for nearly everyone on the planet, even lab rats. As I entered the lab, I noticed something unusual: the three driver-trained rats eagerly ran to the side of the cage and jumped up, like my dog ​​does when asked if he desires to go for a walk.

Had the rats all the time been doing this and I just hadn't noticed? Did they only wish to experience a Froot loop or were they expecting the ride itself? Whatever the case, they gave the impression to be feeling something positive – perhaps excitement and anticipation.

Behaviors related to positive experiences are related to joy in humans, but what about rats? Did I see something like joy in a rat? Maybe so, provided that neuroscientific research increasingly suggests so Joy and positive emotions play a critical role within the health of each human and non-human animals.

In doing so, my team and I even have shifted the main focus from topics comparable to the impact of chronic stress on the brain to the query of how positive events – and the anticipation of those events – influence neural function.

Collaboration with a postdoctoral researcher Kitty HartvigsenI designed a brand new protocol that uses waiting times to extend anticipation of a positive event. Incorporating Pavlovian conditioning, rats had to attend quarter-hour after a Lego brick was placed of their cage before receiving a Froot Loop. They also had to attend of their transport cage for a couple of minutes before entering Rat Park, their play area. We also added challenges like having them shell sunflower seeds before eating them.

That became ours Wait for it Research program. We called this latest series of studies UPERs—unpredictable positive experiential responses—during which rats were trained to attend for rewards. In contrast, control rats received their rewards immediately. After a couple of month of coaching, we subject the rats to numerous tests to find out how waiting for positive experiences affects their learning and behavior. We are currently peering into their brains to map the neural footprint of prolonged positive experiences.

Preliminary results suggest that rats forced to attend for his or her rewards show signs of switching from a pessimistic cognitive style to an optimistic one in a test measuring rodent optimism. They performed higher on cognitive tasks and were bolder of their problem-solving strategies. We linked this program to our laboratory's broader interest in Behavioral medicationsa term I coined to suggest that experiences can change brain chemistry in an identical method to drugs.

This research provides further evidence of how anticipation can reinforce behavior. Previous work with laboratory rats has shown that rats that press a bar to receive cocaine – a stimulant that increases dopamine activation – already feeling a dopamine rush as they expect a dose of cocaine.

The story of rat tails

It wasn't just the results of anticipation on rat behavior that caught our attention. One day, a student noticed something strange: One of the rats within the group, trained to expect positive experiences, had an upward-pointing tail with a curve at the top that resembled the handle of an old-fashioned umbrella.

I had never seen this in my many years of working with rats. When we reviewed the video footage, we found that the rats that were trained to anticipate positive experiences were more prone to hold their tails up than untrained rats. But what exactly did that mean?

Curious, I posted an image of the behavior on social media. Other neuroscientists identified this as a gentler type of what is named Straub tailtypically observed in rats given the opioid morphine. This S-shaped curl is just too linked to dopamine. When dopamine is blocked, Straub's tail behavior decreases.

Natural types of opiates and dopamine — key players in brain pathways that reduce pain and increase rewards — look like telltale components of the raised ends in our anticipation training program. Observing tail posture in rats adds a brand new level to our understanding of rat emotional expression and reminds us that emotions are expressed throughout the body.

While we will't directly ask rats whether or not they enjoy driving, we have now developed a behavioral test to evaluate their motivation to drive. Instead of just giving the rats the chance to drive to the Froot Loop Tree this time, they may also walk – or on this case, paw – a shorter distance.

Surprisingly, two of the three rats selected the less efficient route of turning away from the reward and running to the automobile to drive to their Froot Loop destination. This response suggests that the rats enjoy each the journey and the worthwhile destination.

Rat lessons to benefit from the journey

We're not the one team studying positive emotions in animals.

Neuroscientist Jaak Banksepp famous tickled ratsshow their Ability to enjoy.

Research has also shown that a low-stress environment is desirable for rats retune their brain's reward circuitscomparable to the nucleus accumbens. When animals are kept of their preferred environment, the world of ​​the nucleus accumbens that responds to appetitive experiences expands. Conversely, when rats are kept in stressful environments, the anxiety-provoking zones of their nucleus accumbens expand. It's as if the brain is a piano that may tune the environment.

The neuroscientist Curt Richter also advocated for this Rats which have hope. In a study that wouldn't be allowed today, rats swam in glass cylinders full of water and eventually drowned from exhaustion in the event that they weren't rescued. Laboratory rats, often handled by humans, swam for hours to days. Wild rats gave up after just a couple of minutes. However, when the wild rats were rescued for less than a short while, their survival time increased dramatically, sometimes by days. It seemed that the rescue gave the rats hope and spurred them on.

The Driving Rats project has opened latest and unexpected doors in my behavioral neuroscience research lab. While it’s important to look at negative emotions comparable to fear and stress, positive experiences also shape the brain in significant ways.

As animals—human or otherwise—address the unpredictability of life, anticipating positive experiences helps foster persistence to proceed looking for life's rewards. In a world of fast gratification, these rats offer insights into the neural principles that govern on a regular basis behavior. Instead of pushing buttons for fast rewards, they remind us that planning, forethought and having fun with the ride may be the important thing to a healthy brain. There's a lesson here, my lab rats taught me well.

Think back to a time if you needed a fast answer, perhaps for a recipe or DIY project. Just a few years ago, most individuals's first instinct was to “Google it.” However, as of late, many persons are more more likely to have it Grab ChatGPTOpenAI's conversational AI that’s changing the way in which people seek for information.

Rather than simply providing lists of internet sites, ChatGPT gives more direct, conversational answers. But can ChatGPT do greater than just answer easy questions? Can it actually help people be more creative?

I Study latest technologies and consumer interaction with social media. my colleague Byung Lee and I got down to explore this query: Can ChatGPT really help people solve problems creatively and do it higher than traditional search engines like google and yahoo like Google?

That's what we present in a series of experiments in a study published within the journal Nature Human Behavour ChatGPT promotes creativityespecially in on a regular basis, practical tasks. Here's how this technology is changing the way in which people solve problems, brainstorm ideas, and think creatively.

ChatGPT and inventive tasks

Imagine you're searching for a creative gift idea for a teenage niece. In the past, you’ll have googled “creative gifts for teenagers” after which browsed through the items until something clicked. Now, if you ask ChatGPT, it generates a direct answer based on analyzing patterns across the net. It might be a custom DIY project or a novel experience where the concept is implemented in real time.

To discover whether ChatGPT outperforms Google on creative considering tasks, we conducted five experiments wherein participants tackled various creative tasks. For example, we randomly assigned participants to either use ChatGPT for support, use Google search, or generate ideas themselves. Once ideas were collected, external judges, unaware of the conditions assigned to participants, evaluated each idea for creativity. We averaged the judges' rankings to get an overall creativity rating.

One task was to develop ideas for reusing on a regular basis objects, comparable to transforming an old tennis racket and garden hose into something latest. Another asked participants to design an revolutionary dining table. The goal was to check whether ChatGPT could help people find more creative solutions than using an internet search engine or simply their very own imagination.

The results were clear: the judges rated ideas generated with the support of ChatGPT as more creative than those generated with Google searches or with none help. Interestingly, ideas generated using ChatGPT – even with none human modification – achieved higher creativity than those generated using Google.

A notable insight was ChatGPT's ability to incrementally generate creative ideas: people who improve or construct on what already exists. While truly radical ideas for AI could still be difficult, ChatGPT distinguished itself by proposing practical yet revolutionary approaches. In the toy design experiment, for instance, participants using ChatGPT created imaginative designs, comparable to converting a leftover fan and paper bag right into a wind-powered vehicle.

Limits of AI creativity

ChatGPT's strength lies in its ability Do not mix unrelated concepts convert right into a coherent answer. Unlike Google, which requires users to look through links and compile information, ChatGPT offers a built-in response that helps users articulate and refine ideas in a classy format. This makes ChatGPT a promising creativity tool, especially for tasks that connect different ideas or generate latest concepts.

However, it is crucial to notice that ChatGPT doesn’t produce any truly novel ideas. It then recognizes and combines linguistic patterns from its training data Generate outputs with the most probably sequences based on his training. If you're searching for a technique to improve an existing idea or adapt it in a brand new way, ChatGPT generally is a helpful resource. But for something groundbreaking, Human ingenuity and imagination are still essential.

Additionally, while ChatGPT can generate creative suggestions, these are usually not at all times practical or scalable without expert input. Steps comparable to screening, feasibility checks, fact checking and market validation require human expertise. Because ChatGPT's responses may reflect biases within the training data, people should exercise caution in sensitive contexts comparable to race or gender.

We also tested whether ChatGPT could help with tasks which are often considered to require empathy, comparable to repurposing valuables that a loved one values. Surprisingly, ChatGPT increased creativity also in these scenariosto generate ideas that users found relevant and thoughtful. This result challenges the idea that AI cannot help with emotionally motivated tasks.

Future of AI and creativity

As ChatGPT and similar AI tools turn out to be more accessible, they open up latest possibilities for creative tasks. Whether at work or at home, AI could help with brainstorming, problem solving, and improving creative projects. However, our research also shows that caution is warranted: while ChatGPT can enhance human creativity, it doesn’t replace the unique human capability for truly radical, unconventional considering.

This shift from Googling to asking ChatGPT represents greater than just a brand new technique to access information. It marks a shift in the way in which people collaborate with technology to think, create and innovate.

The California Department of Public Health reported the fourth case of an individual within the state infected with bird flu on Thursday afternoon.

The infected person was from the Central Valley and had contact with infected dairy cows. All 4 people had contact with infected animals on 4 different farms. Authorities concluded that there was no known connection between any of the confirmed cases, suggesting the disease spread directly from animals to humans.

State health officials were also notified of two additional possible human cases of avian influenza within the Central Valley, samples were collected and sent to the CDC for confirmation.

Those infected showed mild symptoms, including eye redness or discharge, and none were hospitalized. The risk of avian flu infection to most of the people is low, however the state health department expects more avian flu cases amongst individuals who interact with infected dairy cows.

Bird flu, also often known as bird flu, is a viral infection that the majority commonly affects birds. it could impact wildlife and reduce food supplies. People will be infected, but person-to-person transmission of the virus is rare. The H5N1 virus is essentially the most common pathogen causing bird flu in humans. According to the Cleveland ClinicThe death rate from bird flu in humans is over 50%.

Some individuals with bird flu may experience only mild symptoms or no symptoms in any respect, but many turn into seriously in poor health. Symptoms include fever, fatigue, cough, muscle aches, sore throat, nausea and vomiting, diarrhea, stuffy or runny nose, and shortness of breath.

On Thursday, the California Department of Food and Agriculture announced that 99 dairy herds in Central California were infected with bird flu. State health officials beneficial personal protective equipment for those working with animals or materials that could be infected with the bird flu virus, equivalent to face shields or goggles to guard eyes, N95 masks and gloves.

According to the California Department of Food and Agriculture, this current nationwide outbreak of bird flu in poultry began in 2022. It was first identified in dairy cows in March.

Federal scientists took samples from the primary two people within the Central Valley infected with bird flu to seek out out whether the virus mutates in ways in which make it more more likely to infect other people, turn into proof against antiviral drugs or cause serious illness. The tests would also show whether the employees were infected from cattle they worked with or elsewhere, and the way the disease spread from state to state. The results of this test are still pending.
