Tomorrow is Black Friday, the official start of certainly one of the most important sales events of the 12 months.

With so many consumers still affected by the falling cost of living, expect bargain hunters to hit the road again in droves.

While some sales have already begun, market research firm Roy Morgan Estimates Australian shoppers will spend a record $6.7 billion throughout the four-day shopping window. That is greater than 5% greater than within the previous 12 months.

For Australians, it’s certainly one of three major annual sales events. The others happen at the top of every financial 12 months (EOFY) and on Boxing Day.

Although Black Friday has only recently arrived in Australia, it has quickly develop into certainly one of the most important shopping days of the 12 months.

It's no easy task for consumers to navigate these offers and avoid retailers' marketing ploys. Here's what you must know:

What exactly is Black Friday?

Black Friday as a serious sales event has its origins within the USA. It falls on the day after Thanksgiving, which is well known on the fourth Thursday of November every year.

The weekend after Thanksgiving typically sees a four-day sales window, including “Cyber ​​Monday” – an identical event recently launched to encourage online shopping.

But as you’ll have noticed, this official launch date doesn't stop retailers from discounting products earlier, which many do.

Australians don’t officially have a good time Thanksgiving. Nevertheless, the sales event has develop into significantly more necessary here during the last decade.

This was initially driven by the massive US firms operating here, comparable to Apple and Amazon. But it was soon adopted and eventually adopted by Australia's own major retailers.

Some Australian retailers at the moment are saying Black Friday has already happened outdated Boxing Day develop into its premier sales event, a repute it could well cement further this 12 months.

It was a similar story in large parts of the world. Countries like Canada, Brazil, France and the United Kingdom at the moment are celebrating the occasion with their very own major sales events.

How do big sales work?

Black Friday and other big sales events are designed to create a way of urgency. They lean heavily on the phenomenon often called Fear of missing out – called FOMO for brief.

Retailers know that shoppers feel pressure to purchase once they fear missing out on something. That's what it's called Scarcity marketing.

Retailers have ways to create artificial scarcity, which might pressure us to make purchasing decisions that aren’t in our greatest interest.

You've probably seen phrases like “Only two left!” in stores and online. or “only today”. These tactics are designed to get you to take motion.

The extent of savings may additionally depend upon retailers' dynamic pricing policies. Many firms use algorithms to regulate discounts in real time based on customer demand, inventory levels and competitive trends.

Popular items can start with small discounts, while less popular products receive larger discounts to generate interest.

How to Become a Smart Buyer

With these aspects in mind, there are some strategies that may allow you to stay clear-headed.

One tactic is to create a shopping list and understand the importance of sticking to predetermined purchasing decisions and a predetermined budget. Prioritize needs over impulsive desires.

For example, if it’s good to replace an old keyboard as a part of a giant sale, set a budget before you begin looking and avoid buying a completely recent computer simply because it's on sale in the shop.

Buyers should prepare for fluctuating prices while also being wary of tactics comparable to artificially inflated “fake” discounts, where original prices are exaggerated to make savings appear more attractive.

Our previous one Research has shown that price promoting can trigger emotions comparable to surprise and expected regret in customers, thereby influencing their purchasing decisions.

Go in with a plan

Another tactic is to window shop within the days or perhaps weeks beforehand. This means that you can review and research the products you’re all for. Note their non-sale prices for future reference.

Make a listing of shopping options and a few alternatives. If possible, try on shoes and clothing and write down your size. This can allow you to act quickly once the sale goes live.

And in the thrill of all of the sales, don't forget: If you don't actually want or need anything, there's at all times the choice of not shopping in any respect.

Every October, when the times get shorter and the air gets more energizing, Millions of Americans Prepare for the favored – and infrequently sugar-filled – Halloween tradition. From jack-o-lanterns that light up porches to costumes that range from the bizarre to the bloodthirsty, Halloween is a time stuffed with playful frights, childhood memories and, after all, candy.

But because the packages pile up and the sugar rush hits, something far more sinister is brewing beneath the surface: the negative effects of sweets in your gut health.

Sugar and other ingredients in Halloween treats can captivate the trillions of microorganisms that live in your gut, collectively called the gut microbiome. As Gastroenterologist and intestinal microbiome researcher At the University of Washington School of Medicine, I dedicated my profession to unlocking the important thing to how food affects this microbial community in your gut.

While no candy is actually healthy, some options are higher in your gut than others. And there are methods you may awaken your gut from the sugar magic after your holiday indulgence.

Gut-busting treats

What is all this candy doing to your gut?

When healthy, your gut microbiome acts like a microbial factory. It digests nutrients your body can't – like fiber and colourful, health-promoting plant compounds Polyphenols – and produces vital molecules so-called metabolites which protect against infections and support brain health. It also regulates metabolism, or the conversion of food into useful components that fuel and grow cells.

A balanced weight-reduction plan ensures that the microbial cauldron of your intestines functions easily. But the concentrated one Sugar, saturated fat And Additives in sweets can mess all the pieces up by feeding inflammatory microbes that weaken your intestinal barrier – the protective layer that separates your microbiome from the remainder of the body.

Once the intestinal barrier is breached, even friendly microbes can trigger inflammation, which might result in health problems Overweight to obesity, Infections To Autoimmune diseaseAnd mild cognitive impairment as much as Alzheimer's disease.

Sugar and inflammation affect your microbiome's ability to digest food and regulate metabolism. Instead of manufacturing healthy by-products – like butyrate from fiber and urolithin A from polyphenols – Sweets that lack these nutrients can trick your system into storing more fat, providing less energy in your muscles and brain.

Too much sweets also can affect your immune system. A healthy gut microbiome helps your immune system distinguish between friend and foe, reducing the chance of infections and autoimmune diseases. Sugar and inflammation undermine that The role of the microbiome in training the immune system to tell apart between harmful invaders and harmless substances. Without a fastidiously calibrated immune system, your body may not fight infections effectively or respond strongly to its own cells.

Neurologically, an excess of sweets also can have a negative impact on the disease Gut-brain axisthe two-way communication between the gut and the brain. Normally a healthy microbiome produces neurotransmitters and metabolitesakin to serotonin and butyrate, which influence mood and cognitive performance. Sugar and inflammation impact and contribute to the role of the microbiome in mental health and cognitive function depression, Fear And Memory problems.

The candy puzzle

Not all Halloween treats are created equal, especially in relation to their dietary value and effects on gut health. Sugar-coated nuts and fruits like honey-roasted almonds and candy apples are among the many front runnersoffers whole food advantages right under the sugary shell. Packed with fiber and polyphenols, they support intestinal health and a healthy metabolism.

On the opposite end of the spectrum are chews like candy corn, Skittles, Starbursts and Twizzlers. These sugary confections are primarily made up of high fructose corn syrup, saturated fat, and additives. They can increase the variety of unsavory bacteria in your gut and cause inflammation, making them certainly one of the unhealthiest Halloween options.

However, chocolate-based candies are proving to be a more microbiome-friendly option. While varieties like Twix, Three Musketeers and Milky Way contain only a small amount of chocolate, pure chocolate bars – especially dark chocolate – are wealthy in fiber and polyphenols. In moderation, dark chocolate with no less than 80 to 85% cocoa can actually be useful Gut microbiome and mood by promoting the expansion of useful bacterial species.

Chocolates with whole nutsE.g. almonds or peanuts, contain a number of fiber, protein and omega-3 fatty acids, making them a healthier selection. Dark chocolate with nuts is best. But in relation to Halloween treats, Peanut M&Ms, 100 Grands, and Almond Joys could also be higher selections than Rolos, Krackels, and Crunches. Even candies with processed nuts, like Reese's Peanut Butter Cups and Butterfingers, contain small amounts of fiber and protein, making them preferable to nut-free options.

At the tip of the list, along with chewy candies, are pure sugar candies akin to lollipops, Jolly Ranchers, gummy bears and Smarties. These sweets lack dietary value and their high sugar content can contribute to the expansion of unhealthy bacteria in your gut microbiome.

Ultimately, all sweets contain high levels of sugar, which may be harmful if consumed in large quantities. Moderation and an otherwise balanced weight-reduction plan are key to having fun with Halloween treats.

Regain balance after enjoyment

If the microbiome is critical to health and candy can upset its balance, how will you restore gut health after Halloween?

A straightforward strategy is to concentrate on the 4 F's food: fiber, phytochemicals, unsaturated fats and fermented foods. These dietary components will help support intestinal health.

Fiber-rich foods akin to whole grains, nuts, seeds, beans, fruit and veggies regulate digestion and nourish useful intestinal bacteria.

Polyphenol-rich foods like dark chocolate, berries, red grapes, green tea, and additional virgin olive oil help reduce inflammation and promote the expansion of healthy gut bacteria.

Unsaturated fats akin to omega-3 fats, walnuts, chia seeds, flax seeds, avocados and fatty fish akin to salmon also can support a healthy microbiome.

Fermented foods like sauerkraut, kimchi, yogurt, kefir, and miso help replenish useful bacteria and restore intestinal balance.

To make tracking your weight-reduction plan easier, think about using a food calculator to measure how well your meals align with the 4 Fs and microbiome-friendly options. Like a virtual “magic book” an internet tool will help ensure your food selections support your gut health and ward off the results of sugar overload.

My daughters often remind me that it's okay to treat yourself to just a few treats once in a while. But remember: moderation is essential. Eating a balanced weight-reduction plan will keep your gut healthy and robust long after the Halloween season ends.

You could have heard that artificial intelligence will revolutionize all the pieces, save the world, and provides everyone superhuman powers. Or you will have heard that it can take your job, make you lazy and silly, and switch the world right into a cyberpunk dystopia.

Look at AI from a special perspective: as an assistive technology – something that helps you function.

In this context, it’s best to also consider a community of experts in giving and receiving help: the incapacity community. Many disabled people make extensive use of technology, each specialized assistive technologies akin to wheelchairs and general-use technologies akin to smart home devices.

Likewise, many disabled people receive skilled and occasional help from other people. And despite stereotypes on the contrary, many disabled people repeatedly help disabled and non-disabled people of their environment.

People with disabilities have extensive experience in receiving and giving social and technical assistance, making them a helpful source of insights into how people might interact with AI systems in the longer term. This potential is a very important driver for my work as a disabled person and Researchers in the sphere of AI and robotics.

Actively learning to live with help

Although virtually everyone values ​​independence, nobody is totally independent. Each of us relies on others to grow our food, look after us once we are sick, give us advice and emotional support, and help us in hundreds of other interconnected ways. Disabled people have support needs that transcend the standard and are subsequently way more visible. Because of this, the disabled community has grappled with what it means to need assistance to live more clearly than most non-disabled people.

This perspective from the incapacity community may be invaluable in relation to developing latest technologies that may help each disabled and non-disabled people. You cannot replace faking a disability with Experience of really being disabledbut accessibility can profit everyone.

This is typically known as Curb effect the best way through which installing a ramp within the curb to make it easier for wheelchair users to cross the sidewalk also advantages individuals with strollers, trolleys and bicycles.

Partnership support

You've probably had the experience of somebody attempting to show you how to without listening to what you actually need. For example, a parent or friend might “help” you clean and as a substitute hide all the pieces you wish.

Disability advocates have long been fighting against this sort of well-intentioned but intrusive help – for instance by Spikes on wheelchair handles to forestall people from pushing someone in a wheelchair without being asked to accomplish that, or to advocate for services that Maintain control of the disabled person.

The disability community as a substitute offers a model of support as a community effort. Applying this model to AI may help be sure that latest AI tools support human autonomy slightly than taking it over.

A key goal of my lab's work is to develop AI-powered assistive robotics that treats the user as an equal partner. We have shown that this model just isn’t only helpful, but essential. For example, most individuals have difficulty moving a robot arm with a joystick: the joystick can only move front to back and side to side, however the arm can move in almost as many directions as a human arm.

To help, the AI ​​can predict what someone is planning on doing with the robot after which move the robot accordingly. Previous research assumed that folks would ignore this help, but we found that folks quickly found out that the system was doing something, actively worked to know what it was doing, and tried to work with the system to make them do what they wanted.

Most AI systems don’t make this easy, but my lab’s latest approaches to AI allow humans to influence robot behavior. We have shown that this leads to raised interactions in Tasks which can be creative, akin to paintingWe have also began to explore how people can use this control to resolve problems outside the areas for which the robots were developedFor example, people can use a robot trained to hold a cup of water to pour the water to water their plants.

Training AI for human variability

The disability-centered perspective also raises concerns in regards to the huge data sets that underpin AI. The essence of data-driven AI is to search for common patterns. In general, the higher something is represented in the information, the higher the model will perform.

If disability signifies that your body and mind don’t conform to normal, then disability signifies that you are usually not well represented in the information. Whether it’s AI systems designed to detect cheating on exams, as a substitute, the popularity of disabilities of scholars or robots that Do not consider wheelchair usersThe interaction of disabled individuals with AI shows how fragile these systems are.

One of my goals as an AI researcher is to make AI more responsive and adaptable to real-world human differences, especially for AI systems that learn directly from interactions with humans. We have developed frameworks for testing how robust these AI systems are to real human teaching and investigated how robots can learn higher from human teachers even when these teachers change over time.

By viewing AI as an assistive technology and learning from the incapacity community, we may help be sure that the AI ​​systems of the longer term meet people’s needs – while keeping people on top of things.

If you are taking a better have a look at a plant in your park, your garden, and even your kitchen, you'll probably see damage. Whether a caterpillar has gnawed off a part of a leaf or a mealybug is sucking sap, animals feed on plants on a regular basis.

Of course, herbivory, or eating plants, is just not ideal for a plant's survival, so plants have evolved many various defense mechanisms to counteract this threat, including physical and chemical weapons. Cacti, for instance, are equipped with spines that pierce skin. Herbs reminiscent of mint, lavender, and rosemary produce volatile scents that might help deter herbivores.

Other plants bribe their bodyguards by secreting thick, sweet nectar.

Nectar is mostly related to flowers, where it’s used to draw bees, birds or butterflies to move pollen from one flower to a different. But other plants also produce other forms of nectar glands, called extrafloral nectariesPlants produce these glands to bribe ants with a sweet reward; in return, the ants defend the plant from herbivorous insects.

I study Evolutionary biology of plantsand recently worked with Fern biologist Fay-Wei Li At the Boyce Thompson Institute and Cornell University Ant biologist Corrie Moreau to research the evolution of ant defense mechanisms in plants.

We found something amazing: almost 130 million years ago, throughout the Cretaceous period, ferns and flowering plants Ant bribery nectar glands developed independently at concerning the same timeWe found this out by utilizing complex algorithms to estimate the evolutionary origins and history of ferns, flowering plants, and ants.

This cut-off date is sort of interesting since it was very early within the evolutionary history of flowering plants, but quite late in Evolutionary history of the fernOur work has shown that old dogs can learn some recent tricks – and, more importantly, how this happened in ferns.

Meeting above ground

Plants are the first producers of just about all food on Earth, so virtually all living things rely upon them for survival. For this reason, herbivory is a component of life. But it also imposes significant costs on many industries, from houseplants to crops. Major pest infestations may even threaten global food security.

For all these reasons, understanding how plants defend themselves against predators is an important challenge.

The evolution of ant-based defense strategies inextricably linked two lineages in the dominion of life. This meant that ants and plants ultimately evolved together – a process called coevolutionWhen one species changes, the opposite may change in response, and these changes may even be encoded of their genes.

Flowering plants emerged within the Cretaceous period about 150 million years ago, and our analyses showed that they formed close bonds with ants early on. These flowering plants and their ant partners appear to have co-evolved over time.

However, this was not the case with ferns. Although they’d the potential to evolve nectaries concurrently flowering plants, they only began to rapidly evolve nectaries once they learned to live amongst trees.

Ferns were originally land plants, but after flowering plants evolved into large trees, jumped onto their branches as epiphytes – Plants that grow on other plants, often with none connection to the soil.

Ferns may also climb up trees, like ivy, or form their very own trunk, like Tree ferns. This also helped the ferns to succeed in the treetops.

The undeniable fact that ferns didn’t produce nectar for ants until they moved to trees puzzled me as a fern biologist. That was until my co-author Corrie Moreau identified that the majority ants live in treetops.

This was entirely logical. When ferns became cover dwellers, they became closer to ants, which were already related to nectar-bearing trees. By interbreeding with these ants, the ferns eventually took advantage of the established, mutually useful relationship between the ants and flowering plants.

The evolution and ecology of fern-ant relationships

While our study uncovered recent features of ant-mediated plant defense, it left many questions unanswered. For example, are some ants specialized on ferns, or are they generalists that may feed on nectar from a greater diversity of plants? How exactly did plants originally evolve the physical ability to provide extrafloral nectar? Are the genes encoding nectar development the identical in ferns and flowering plants? Is the chemistry of nectar from ferns and flowering plants the identical?

Our study lays the inspiration for further research into the evolution and ecology of those nectaries. This is significant basic research. It can be conceivable that research on this area could contribute to breeding programs that promote nectary-mediated ant defense, thereby reducing the necessity for pesticides to guard plants from predators.
