Less waste, higher profits

Within three weeks, South Korea experienced one transient declaration of martial lawits sudden cancellation and the impeachment its president Yoon Suk Yeol.

An underappreciated driver of the recent drama is the rise of YouTube agitators, activists and influencers who’re making the most of and fueling a brand new sort of populism. The impact in South Korea is serious – however the trend is global.

An extremely online constituency

In the 2022 South Korean election, Yoon trailed his opponent for much of the campaign. He is aggressive Populist politics received some support, nevertheless it gave the look of it will fail.

Then he found it a brand new constituency – a gaggle of lively and partisan young men who campaigned for the abolition of the Ministry of Gender Equality and Family. These agitators used YouTube and other platforms to spread their message.

This crowd, together with traditional conservative voters, allowed Yoon a narrow victory and control of South Korea's strongest political position. He then duly abolished The gender ministry said structural sexism was “a thing of the past”.

After gaining power, Yoon relented Arrest warrants for several of his supposed political opponents. Among these was Kim Yeo Juna critical and inflammatory YouTube journalist and a polarizing populist figure with ties to liberal politics. Kim's weekly videos Send news, guest interviews and snarky comments to hundreds of thousands of lively followers.

We have turn out to be accustomed to the concept that social media platforms Influence democratic processes by disseminating news and evaluation and by directing users' attention by recommending specific content. However, the increasing political visibility of platform actors like Kim suggests that the influence is becoming more direct.

Platforms for populist news and views

Social media platforms provide access to a big selection of stories and media producers, from mainstream media outlets to independent commentators at the acute ends of the political spectrum. However, not all news receives the identical attention.

Research shows, no less than in South Korea, fake news receives more likes and interactions than verifiable messages. “Real news” is commonly dismissed and ridiculed.

Further South Korean research shows residents could also be using platforms Look for conspiracy theories and despise unpopular political groups or decisions. Users also notorious direct hatred on topics comparable to women's rights.

These problems will not be limited to South Korea. Polarizing and populist news and evaluation is a worldwide phenomenon.

Trust in traditional news media is declining, partly due to fear in keeping with elite and powerful personalities. These fears are sometimes confirmed Social media influencer who wish to turn out to be the brand new opinion leaders.

Online influencers are great vehicles for populist politics. They normally have close relationships with their viewers suggest easy solutionsand frequently resist accountability and fact-checking.

Platforms are sometimes more more likely to recommend polarizing and even radicalizing content for viewers, crowding out more balanced content.

Platforms for journalism?

However, these polarizing personalities will not be alone in these areas. Experienced journalists and newcomers get used to the platforms and still provide reliable information.

On YouTube, former mainstream journalists, comparable to B. Australia Michael West and the American Phil Edwardshave built a following while combining personal and casual content with more traditional journalism.

Non-journalists, comparable to Money & Macro and the English Tom Nicholashave expanded their influence by adopting some basic journalistic practices. With the support of their many viewers, they produce content that researches, explores and explains current news and evaluation.

These YouTube news influencers show that journalistic content can contribute to the brand new news media ecosystem and attract large audiences without counting on populist and polarizing content.

“Newsfluencer” produce Journalism on platformsB. YouTube, adapt their content to the conventions of the platforms.

Newsfluencer and the long run

Newsfluencers often film in informal settings moderately than traditional sets, constructing an informal relationship with their audience. They use “authenticity” and exit of their method to “Avoid looking like polished corporate media“.

Their diverse sources of income include advertisements, sponsors, merchandise and, most significantly, direct audience contributions. These contributions may be made through memberships or through third-party platforms comparable to Patreon and Substack.

Even major news organizations like Australia's ABC have began adopting YouTuber norms. While the present podcast was produced under the auspices of the national broadcaster If you listenFor example, with its casual style and deal with giving the audience what they need, it significantly outperforms traditionally formatted content.

In South Korea there are YouTube channels like VoiceOfSeoul Take similar steps and mix street reporting with informal talk show panels and investigative journalism. OhMyTV combines YouTuber and breaking news styles and includes hyperlinks for private contributions and sponsorships.

At the identical time, legacy media like KBS maintains a powerful following via TV and portal sites like Naver. However, KBS's conventional format is struggling to realize comparable viewership on the increasingly dominant platforms on which these unconventional journalists thrive.

There is a transparent space for journalism on YouTube and similar platforms. However, it has to adapt.

As the South Korean experience shows, the time may come when platform journalism is crucial to democracy.

The busiest domestic routes

Busiest domestic routes by region

The old saying “speed kills” also applies to the world's fastest roller coasters, whose closures have been worryingly quick – but luckily for thrill-seekers, a brand new roller coaster king will soon emerge in 2025.

Kingda Ka at Six Flags Great Adventure in New Jersey — the reigning champion for speed (128 miles per hour) and height (456 feet) — was the last of the world's fastest roller coasters to topple.

Six Flags will spend $1 billion on 11 roller coasters over the subsequent two years

Six Flags announced last week that Kingda Ka can be removed in 2026 and replaced with a brand new record-breaking launch coaster.

“Kingda Ka has provided more than 12 million rides since 2005,” Six Flags said in an announcement. “What was cutting-edge roller coaster technology 20 years ago has been surpassed by more modern advances.”

There are 4 more coasters The world's fastest list from the Roller Coaster Database are currently “standing but not operational”.

That works Red power (112 miles per hour) in Spain's Ferrari Land because the reigning fastest roller coaster on the planet.

The Fury 325 (95 mph) at Carowinds, North Carolina currently holds the title America's fastest roller coaster.

According to Magic Mountain officials, the “Superman: Escape from Krypton” roller coaster was closed in September for repairs. A reopening date has not yet been announced.

The record-breaking roller coaster opened at Magic Mountain in 1997 as Superman: The Escape, making it the fastest roller coaster on the planet.

The nearly equivalent Intamin Shuttle roller coasters shared the throne until the 112 mph Dodonpa roller coaster opened in Japan's Fuji-Q Highlands in 2001.

Cedar Point's Top Thrill Dragster took the title of fastest roller coaster on the planet in 2003 with a top speed of 120 miles per hour.

Kingda Ka became king of the world when the Intamin Accelerator cylinder coaster got here onto the market in 2005.

Formula Rossa took the world's fastest title in 2010, however the coaster has been closed since January to repair the launch system – a process that officials say could take a yr or longer Screamscape.

Ring Racer stays an expensive but worthless white elephant – it was only operational for a number of days when it opened in 2013, but to today it “stands but is not operational”.

Ferrari World's Formula Rossa, Cedar Point's Top Thrill 2 and Magic Mountain's Superman are all expected to reopen sooner or later.

Cedar Point closed Top Thrill Dragster for your complete 2022 and 2023 seasons after a bit of metal flew off the ride in August 2021, seriously injuring a lady waiting in line on the attraction.

The renamed Top Thrill 2 replaced Intamin's hydraulic launch system with a Zamperla electromagnetic launch system in May – however the ride only operated for about every week before the park closed the coaster again as a result of mechanical problems.

The list of the fastest roller coasters on the planet can be reshuffled again in 2025 Falcon flight debuts at Six Flags Qiddiya City in Saudi Arabia.

Falcon's Flight becomes the fastest roller coaster on the planet at a blistering 155 miles per hour – 6 miles per hour faster than Formula Rossa's top speed of 149 miles per hour.

In my research As I've focused on the early farmers of Europe, I've often wondered a couple of strange pattern over time: farmers lived in large, dense villages, then dispersed over centuries, later founding cities again, only to desert those as well. Why?

Archaeologists often explain what we call urban collapse Climate changeOverpopulation, social pressure or something similar Combination of those. Each of those was probably true at different times.

But scientists have added a brand new hypothesis to the combination: disease. The close coexistence with animals led to this zoonotic diseases that got here to contaminate people too. Outbreaks could have led to dense settlements being abandoned, at the least until later generations found a option to make their settlement structure more immune to disease. In a brand new study, my colleagues and I analyzed the fascinating floor plans of later settlements to see how they might have interacted with disease transmission.

Earliest Cities: Dense with People and Animals

Çatalhöyükin what’s now Türkiye, is the oldest farming village on this planet with a history dating back over 9,000 years. Many hundreds of individuals lived in mud-brick houses that were packed so tightly together that residents could get in using a ladder through a trap door on the roof. They even buried chosen ancestors under the home floor. Although there was loads of space on the Anatolian plateau, people crowded together.

For centuries, the people of Çatalhöyük herded sheep and cattle, grew barley and made cheese. Impressive paintings of bulls, dancing figures and others Volcanic eruption suggest their folk traditions. They kept their well-organized homes tidy, sweeping the floors and providing storage containers near the kitchen that sat under the trapdoor to permit oven smoke to flee. To maintain cleanliness, they even needed to re-plaster the inside partitions of their houses several times a 12 months.

These wealthy traditions ended around 6000 BC. BC, as Çatalhöyük was mysteriously abandoned. The population dispersed into smaller settlements in the encircling floodplain and beyond. Other large farming populations within the region had also dispersed, and nomadic pastoralism became more widespread. For the surviving populations, the mud-brick houses were now separate, in contrast to the metropolitan areas of Çatalhöyük.

Was disease a consider the abandonment of dense settlements in 6000 BC? BC?

In Çatalhöyük, archaeologists have found human bones mixed with cattle bones in graves and garbage heaps. There was probably a gathering of individuals and animals zoonotic diseases in Çatalhöyük. Ancient DNA identified Tuberculosis in cattle within the region as early as 8500 BC. BC and TB in human infant bones not long afterwards. DNA in ancient human stays dated Salmonella as early as 4500 BC BC. Assuming that the contagiousness and virulence of Neolithic diseases increased over time, dense settlements resembling Çatalhöyük can have achieved a Turning point where the consequences of disease outweighed the advantages of living close together.

2,000 years later a brand new layout

Around 4000 BC In the 4th century BC, large urban populations reappeared within the mega-settlements of antiquity Trypillia culturewest of the Black Sea. Thousands of individuals lived in mega settlements like Trypillia No longer And Maidanetske in today's Ukraine.

If disease was a consider the spread hundreds of years ago, how were these mega-settlements possible?

This time the layout was different than in crowded Çatalhöyük: the a whole bunch of two-story wood houses were arranged usually in concentric ovals. They also grouped themselves into pie-shaped neighborhoods, each with its own large meeting house. The pottery unearthed from neighborhood meeting houses shows many various compositions, suggesting this These pots were brought there by different families come together to share food.

This layout suggests a theory. Whether the residents of Nebelivka knew it or not, this lower density, cluster arrangement could have helped prevent disease outbreaks from wiping out your entire settlement.

archaeologist Simon Carrignon and I got down to test this possibility by adapting computer models from a previous epidemiology project that modeled how social distancing behaviors play out have an effect on the spread of pandemics. To study how a Trypillian settlement would hinder the spread of disease, we teamed up with a cultural evolution scientist Mike O'Brien and with the archaeologists from Nebelivka: John Chapman, Bisserka Gaydarska And Brian Buchanan.

Simulating socially distanced neighborhoods

To simulate the spread of the disease in Nebelivka, we needed to make some assumptions. At first, we assumed that early diseases were spread through foods like milk or meat. Second, we assumed that folks visited other houses of their neighborhood more often than those outside.

Would this neighborhood clustering be enough to suppress disease outbreaks? To test the consequences of various possible interaction rates, we ran thousands and thousands of simulations, first on a network to represent grouped neighborhoods. We then ran the simulations again, this time on a virtual floor plan modeled after actual site plans, giving the homes in each neighborhood a better probability of coming into contact with each other.

Based on our simulationsWe found that the clustering of homes in Nebelivka would have significantly reduced outbreaks of early foodborne illnesses if people had visited other parts of the town infrequently – a couple of fifth to a tenth as often as other houses in their very own neighborhood. This is sensible considering that every neighborhood had its own meeting house. Overall, the outcomes show how the Trypillian arrangement could help early farmers coexist in low-density urban populations at a time when zoonotic diseases were on the rise.

The residents of Nebilevka needn’t have consciously planned the design of their neighborhood to make sure the survival of their population. But it could be that they do, because human instinct is to avoid them Signs of a contagious disease. As in Çatalhöyük, residents kept their houses clean. And about two-thirds of it Houses in Nebelivka were deliberately burned down at different times. These intentional periodic burns can have been a pest control tactic.

New cities and innovations

Some of the early diseases eventually spread through routes apart from bad foods. Tuberculosis, for instance, was in some unspecified time in the future transmitted through the air. If the bacterium that causes the plague was adapted to fleasit could possibly be spread by rats that don't care about neighborhood boundaries.

Were latest disease vectors an excessive amount of for these ancient cities? The mega-settlements of Trypillia were founded in 3000 BC. Abandoned. As in Çatalhöyük hundreds of years ago, people dispersed into smaller settlements. Some geneticists speculate that Trypillia settlements were abandoned resulting from the origin of the plague within the region, about 5,000 years ago.

The first cities in Mesopotamia emerged around 3500 BC. BC, others soon emerged in Egypt Indus Valley And China. These cities, with tens of hundreds of residents, were filled with specialized craftsmen in numerous parts of the town.

This time people within the inner cities didn’t live side by side with cattle or sheep. Cities were the centers of regional trade. Food was imported into the town and stored in large grain silos just like the one within the Hittite capital Hattusa, which could contain enough grain Feed 20,000 people for a 12 months. Wastewater disposal was supported by public waterworks, resembling: Canals in Uruk or water fountain and a large public bath within the Indus city of Mohenjo Daro.

These early cities, together with those in China, Africa and the Americas, formed the foundations of civilization. Their form and performance have arguably been shaped by millennia of disease and human responses to it, all the best way back to the world's earliest farming villages.

About a 3rd of the world's population, or around 3 billion people, don’t have any or only poor access to the Internet. due to Infrastructure constraints, economic inequalities and geographical isolation.

Today's satellites and ground-based networks leave communication gaps where, for geographical reasons, the installation of conventional ground-based communications equipment can be too expensive.

Elevated platform stations Telecommunications equipment high within the air, in unmanned balloons, airships, gliders and airplanes, could increase social and economic equality by filling gaps in web connectivity on the bottom and by satellite, enabling more people to totally take part in the digital age.

One of us, Mohamed-Slim Alouini, is an electrical engineer who participated in an experiment that showed that it is feasible to offer high data rates and widespread 5G coverage from the stratosphere. The stratosphere is the second lowest layer of the atmosphere and lies between 6 and 48 kilometers above the Earth. Commercial aircraft normally fly within the lower a part of the stratosphere. The experiment measured signals between platform stations and users on the bottom in three scenarios: an individual staying in a single place, an individual driving a automotive, and an individual steering a ship.

My colleagues measured how strong the signal is relative to interference and background noise, a measure of the network's reliability. The results showed that the platform stations can support high-data-rate applications similar to streaming video in 4K resolution and may cover 15 to twenty times more area than traditional terrestrial transmission towers.

Early attempts by on facebook. and Google to commercially use platform stations were unsuccessful. But recent investmentstechnological improvements and the interest of traditional airlines and specialized aerospace startups May Change the equation.

The goal is global connectivity, a priority that can give the concept of ​​platform stations recognition on the 2024 Report on the ten most vital recent technologiesThe international industry initiative HAPS Alliancewhich also includes academic partners, also strives for this goal.

Fast, cost-effective, flexible

Platform stations can be faster, cheaper and more flexible than satellite-based systems.

Since the communication devices are closer to Earth than satellites, the stations could deliver stronger signals with higher capability. This would enable real-time communication that’s fast enough to maintain up with Standard smartphoneshigh-resolution capabilities for imaging tasks and better sensitivity for sensing applications. They transmit data via free-space optics or light beams and large-scale antenna array systems that may send large amounts of information quickly.

Satellites can vulnerable to eavesdropping or jamming if their orbits take them over hostile countries. However, platform stations remain within the airspace of a single country, which reduces this risk.

High-altitude platforms are also easier to put in than satellites, which have high start And maintenance Costs. And the regulatory requirements and compliance procedures required to secure places within the stratosphere are prone to be simpler than the complex international laws that govern satellite orbits. Platform stations are also easier to upgrade, so improvements could possibly be implemented more quickly.

Platform stations are also potentially less harmful to the environment than Satellite mega-constellations This is because satellites burn up after they re-enter the Earth's atmosphere and may release harmful metals, whereas platform stations could be powered by clean energy sources similar to solar energy and green hydrogen.

The fundamental challenges for practical platform stations are to extend their flight time to several months, increase the usage of green electricity on board and improve reliability – especially for automatic take-off and landing within the lower turbulent layers of the atmosphere.

More than satellites

Platform stations could play a critical role in emergency and humanitarian situations by supporting relief efforts when ground-based networks are damaged or non-functional.

The stations is also connected to one another Internet of Things (IoT) devices and sensors in distant environments to raised monitor the environment and manage resources.

In agriculture, the stations could Imaging and sensor technologies to assist farmers monitor crop health, soil conditions and water resources.

Your ability for high-resolution imaging could also support navigation and mapping activities, that are critical for cartography, urban planning and disaster relief.

The stations could also tackle a dual function by Carrying instruments for atmospheric monitoring, climate research and distant sensing of Earth's surface features, vegetation and oceans.

From balloon to airplane

Platform stations could possibly be based on different aircraft types.

Balloons allow for stable, long-lasting operation at high altitudes and could be tethered or free-floating. Airships, also called dirigibles or blimps, use lighter-than-air gases and are larger and more maneuverable than balloons. They are particularly well suited to surveillance, communications and research.

Gliders and powered aircraft could be controlled more precisely than balloons, that are sensitive to fluctuations in wind speed. In addition, powered aircraft, which include drones and fixed-wing aircraft, can power communications equipment, sensors and cameras.

Next generation performance

Platform stations could use various energy sources, including increasingly light And efficient Solar cells, Batteries with high energy density, green hydrogen combustion engines, green hydrogen fuel cellsthat are currently within the testing phase, and eventually Laser beam powered by the bottom. or space-based solar stations.

The Development of sunshine aircraft designs coupled with advances in Highly efficient engines and propellers enable aircraft to fly longer and carry heavier payloads. latest light aircraft may lead to platform stations that may maneuver within the stratosphere for prolonged periods of time.

In the meantime, Improvements in stratospheric weather models and atmospheric models facilitate the prediction and simulation of the conditions under which the platform stations will operate.

Bridging the worldwide digital divide

By the tip of the last decade, it could be possible to make use of platform stations commercially, at the very least for disaster or emergency situations. For example, a consortium in Japan, a rustic with distant mountain and island communities, has earmarked 100 million US dollars for solar powered high altitude platform stations.

Train platforms could bridge the digital divide by improving access to essential services similar to education and healthcare, providing recent economic opportunities, and improving emergency care and environmental monitoring. As technological advances proceed to drive their development, train platforms will play a critical role in a more inclusive and resilient digital future.

SAN FRANCISCO — The world's first industrial hydrogen-powered passenger ferry will begin service in San Francisco Bay, a part of plans to phase out diesel-powered ships and reduce planet-warming carbon dioxide emissions, California officials said Friday at an illustration of the vessel.

The 70-foot catamaran, named MV Sea Change, will carry as much as 75 passengers along the waterfront between Pier 41 and the downtown San Francisco ferry terminal starting July 19, officials said. The service can be free for six months while it operates under a pilot program.

“The implications of this are enormous because this is not the last stop,” said Jim Wunderman, chairman of the San Francisco Bay Area Water Emergency Transportation Authority, which operates commuter ferries across the bay. “If we can operate this successfully, there will be more of these vessels in our fleet and in other people's fleets across the United States, and we think around the world.”

Sea Change can travel about 300 nautical miles and operate for 16 hours before needing to be refueled. The fuel cells generate electricity by combining oxygen and hydrogen in an electrochemical response that releases water as a byproduct.

The technology could help clean up the shipping industry, which accounts for nearly three percent of world greenhouse gas emissions, experts say. That's lower than cars, trucks, rail or aviation, nevertheless it's still lots – and the number is rising.

“The real value of this becomes clear when you multiply it by the number of ferries in operation around the world,” he said. “There is huge potential here. This is how you can start to reduce the carbon intensity of your ports.”

Supporters also hope that hydrogen fuel cells could sooner or later power container ships.

The International Maritime Organization, which regulates industrial shipping, desires to halve its greenhouse gas emissions by the center of the century.

As fossil fuel emissions proceed to warm the Earth's atmosphere, the Biden administration is banking on hydrogen as an influence source for vehicles, manufacturing and electricity generation. It has offered $8 billion to encourage the nation's industry, engineers and planners to determine methods to produce and deliver clean hydrogen.

Environmental groups say hydrogen carries its own pollution and climate risks.

Currently, the hydrogen produced world wide every year, mainly for refineries and fertilizer production, is comprised of natural gas. This process is warming the planet as an alternative of saving it. In fact, a brand new study by researchers at Cornell and Stanford universities has found that when hydrogen is produced, much of it emits carbon dioxide, meaning that hydrogen-powered transportation cannot yet be considered clean energy.

But proponents of hydrogen-powered transportation say hydrogen production will change into more environmentally friendly in the long run. They expect that electricity from wind and solar energy can be increasingly used to separate hydrogen and oxygen into water. As such renewable types of energy change into more widely used, hydrogen production is prone to change into cleaner and more cost effective.

The Sea Change project was financed and managed by investment firm SWITCH Maritime. The vessel was built at Bay Ship and Yacht in Alameda, California, and All-American Marine in Bellingham, Washington.

The world's coral reefs are like underwater cities teeming with fish and marine lifetime of all types. Coral reefs cover lower than 1% of the ocean, but they support An estimated 25% of all marine speciesincluding many vital fish species. The economic value of the services provided by these complex ecosystems is over 3.4 billion US dollars annually within the USA alone

Today, rising sea temperatures threaten the survival of many reefs. If the ocean water stays too warm for too long, corals push out the colourful symbiotic algae called zooxanthellaethat live of their tissues – a process called coral bleaching. These algae provide food for the corals, so bleached corals are vulnerable to starvation and disease and may die if the water doesn't cool quickly enough.

With global ocean heat at record levelsScientists have confirmed that a world coral bleaching is underwaySince the start of 2023 Corals are dying within the Indian, Pacific and Atlantic Oceans, each north and south of the equator.

The current bleaching event in the broader Caribbean region is longer and more severe than any previous bleaching event for the reason that first global event in 1998. I’m studying large-scale climate and ocean dynamics and analyze how biological connections between coral reefs – sometimes extending over great distances – might help reefs recuperate from heat stress.

Reef relationships

As the oceans rapidly evolve, scientists are working to develop response strategies, including making corals more heat-resistant, restoring damaged areas with healthy corals, moving coral nurseries to cooler areas, and operating coral nurseries. Breeding “super corals”“that are more resilient to those stresses; and the development natural chemical signals And Sound signals to draw coral and fish larvae to damaged reefs.

Many fish species present in coral reefs play a crucial role in maintaining the health of those communities. For example, algae compete with corals for space and light-weight and infrequently take over reefs after coral bleaching events.

Corals stay healthier and recuperate faster when surrounded by fish that eat various kinds of seaweed, akin to Parrotfish, surgeonfish and rabbitfishBecause of their role, these species are sometimes referred to collectively as grazers.

Sea cucumbers – leathery bottom dwellers, distantly related to starfish and sea urchins – are also vital partners of the reefs. They feed on bacteria and other organic materials in marine deposits and thus clean the environment of the reefs.

My colleague from Georgia Tech Mark Hay recently published a study showing that removing sea cucumbers from reef communities led to a rise in organic waste and a 15-fold increase in coral deathsProtecting sea cucumbers, that are overfished as a food source, could contribute to the health of coral reefs.

The role of ocean connectivity

Coral reefs should not isolated outposts. When fish and corals spawn, they release thousands and thousands of larvae that drift with the present and are exchanged across the reefs. Mixing and transport processesThis exchange represents the connection between coral reefs.

Some reefs supply larvae to many others. Other reefs are more isolated, so scientists might have to artificially introduce larvae to assist reefs recuperate from coral bleaching and other threats.

Studies show that well-connected reefs recuperate faster from stresses akin to bleachingThe abundant supply of coral and fish larvae washed up from distant by ocean currents helps restore bleached areas and maintain diverse reef communities. Maintaining this connectivity is critical to protecting reefs.

But measuring connectivity is time-consuming and expensive. Researchers collect coral samples from reefs which may be connected and analyze the corals' DNA to reconstruct their genetic history, constructing an image of how strongly different populations are connected.

We also use computer models to simulate ocean currents that carry virtual larvae from their release points to the places where they settle. But currents should not fixed in a single place like highways: their strength and direction change over time, depending on the season and yr. To study reef connectivity, multi-year model simulations have to be carried out that cover small areas intimately, which requires plenty of computational work.

Insights from machine learning

Now, machine learning offers a brand new approach to analyze reef connections. This branch of artificial intelligence enables computers to learn tasks or relationships without being explicitly instructed. Instead, they use algorithms to perform various tasks.

My research group has developed a tool that uses details about ocean currents from satellite data to generate a network of ecoregions, or areas where ecosystems are generally similar. calculates their connectivity during the last 30 to 40 yearsWe then discover higher connected reefs using PageRank centrality – the algorithm developed by Google to measure the recognition of internet sites.

Once we have now defined a network of ecoregions, we are able to determine how “popular” – that’s, how connected – known reefs are. And we are able to check that our algorithms are working well by observing whether “popular” reef communities contain more diverse and healthy coral populations.

We have found that in The Coral Triangle of Southeast Asia – the biggest biodiversity hotspot on Earth – periodic fluctuations between the El Niño and La Niña climate patterns promote biodiversity and are more likely to have done so. within the last 5 to 7 million years. Connectivity during El Niño events may be very different from that in La Niñas because ocean currents are different. These dynamics help reefs by ensuring that they receive larvae from many various locations in several years.

Understanding which coral and environmental characteristics help reefs grow to be more resilient and linking this information to connectivity networks opens up latest opportunities to assist corals survive longer. Together, these approaches show how and where monitoring and restoration efforts ought to be prioritized.

In the long run, the one approach to stop coral death and protect reefs which are home to a lot marine life is Limiting water pollution and mitigate climate change. But localized measures to make reefs healthier should buy them a while and maybe make them more resilient to warming oceans.
