Synthetic mRNA, the ingenious technology behind the Pfizer-BioNTech and Moderna vaccines, might seem like a sudden breakthrough, or a new discovery. One year ago, almost nobody in the world knew what an mRNA vaccine was, for the good reason that no country in the world had ever approved one. Months later, the same technology powered the two fastest vaccine trials in the history of science. Like s
A new experimental treatment could someday give people a way to grow missing teeth , if early research on lab animals holds up.

Major League Baseball is scheduled to hold its 91st All-Star Game at Truist Park in Atlanta on July 13—the first time in 21 years the league's annual showcase is to be played in that city. But pro baseball should extend Atlanta's All-Star drought, and other sports should avoid scheduling their own signature events in Georgia, to show Republican state lawmakers that their latest efforts at voter s
Paging Nick Fury The Pentagon has a bold plan to keep aircraft carriers relevant to the future of warfare: taking them out of the water and lifting them up into the sky. The plan sounds laughably similar to the Helicarriers from the Marvel Cinematic Universe movies, but The Economist reports that DARPA, the Pentagon's research division, is dead serious about getting the program off the ground. Th
Over the past few decades, astrophysicists and cosmologists have gathered various observations hinting at the existence of dark matter (DM), a type of matter that does not absorb, reflect or emit light, and thus cannot be detected using conventional techniques for observing electromagnetic radiation. While physicists have predicted its existence based on astrophysical and cosmological observations
Most people know mother-of-pearl, an iridescent biomineral also called nacre, from buttons, jewelry, instrument inlays and other decorative flourishes. Scientists, too, have admired and marveled at nacre for decades, not only for its beauty and optical properties but because of its exceptional toughness.
The AstraZeneca COVID-19 vaccine is indispensable right now. As one of the first vaccines out of the gate, it's been at the center of the World Health Organization's plan to roll out some 2 billion doses to 92 nations by the end of the year. It's also one of just a handful of vaccines that are already being produced and distributed on such a massive scale that they might change the near-term cour
An interdisciplinary team at Monash University discovered a new universal rule of biological growth that explains surprising similarities in the shapes of sharp structures across the tree of life, including teeth, horns, claws, beaks, animal shells, and even the thorns and prickles of plants.
When humans look out at a visual landscape like a sunset or a beautiful overlook, we experience something—we have a conscious awareness of what that scene looks like. This awareness of the visual world around us is central to our everyday existence, but are humans the only species that experiences the world consciously? Or do other non-human animals have the same sort of conscious experience we do
We are not venomous, and neither are mice—but within our genomes lurks that potential, suggest scientists from the Okinawa Institute of Science and Technology Graduate University (OIST) and the Australian National University. Reporting this week in PNAS, the researchers found that the genetic foundation required for oral venom to evolve is present in both reptiles and mammals.
Despite the enormous amount of research over the decades into lasers and their applications, scientists have difficulty accurately and directly observing fine details of their interactions with materials.

Vincent Migeat / Agence VU / Redux I didn't feel weepy the first time I hugged my two granddaughters postvaccination. What I felt instead was a softening, a physical relief, a deep sense that things could be normal again, as I sank down to the floor with the 2-year-old and let her nestle into my lap. This relief, I thought, is what a vaccine has given me. For months, our interactions had been del

Take a look at the numbers 294,001, 505,447 and 584,141. Notice anything special about them? You may recognize that they're all prime — evenly divisible only by themselves and 1 — but these particular primes are even more unusual. If you pick any single digit in any of those numbers and change it, the new number is composite, and hence no longer prime. Change the 1 in 294,001 to a 7, for instance

So says the narrator of Stanislaw Lem's 1974 short story, "The Mask," in which a young woman struggles to describe the experience of realizing that, under her skin, she is a robot. The story's plot is fast-paced, but the reason the text is compelling—and upsetting—is Lem's skill at bending
A third of the planet's agricultural land is at "high risk" of pesticide pollution from the lingering residue of chemical ingredients that can leach into water supplies and threaten biodiversity, according to research published Monday.
Here on Earth, we have more detailed maps of Mars than of our own ocean, and that's a problem. A massive force for surviving climate change, the ocean absorbs 90% of the heat caused by emissions and generates 50% of the oxygen we breathe. "We have the ocean to thank for so many aspects of our safety and well-being," says Dawn Wright, oceanographer and chief scientist at geographic information sys
The race for the quantum computer will most likely be decided at the quantum bit (qubit) – the smallest information unit of the quantum computer. The coupling of several qubits into a computing system is currently one of the greatest challenges in the development of quantum computers. A key question is which physical system and which material are best suited for qubits. Development of qubits based
A team of researchers, led by the Instituto de Ciencias del Patrimonio (Incipit-CSIC) and the Instituto de Astrofísica de Canarias (IAC), in collaboration with the team from the Arqueological Zone of Caral (Perú) led by Dr. Ruth Shady Solís, has established the relation between the position of the monuments of the Supe Culture (Perú), their orientations, and some astronomical and topographic featu
MIT astronomers have discovered new and unusual galactic neighborhoods that previous studies overlooked. Their results, published today, suggest that roughly 1 percent of galaxy clusters look atypical and can be easily misidentified as a single bright galaxy. As researchers launch new cluster-hunting telescopes, they must heed these findings or risk having an incomplete picture of the universe.
In the 1970s astronomer Vera Rubin was observing the Andromeda galaxy and discovered something very curious. Andromeda is a spiral galaxy, like our own, and spins like a pinwheel. The "spinning" is comprised of all the individual stars (and gas and dust, but the stars are what we can see) revolving around all the mass within their orbit. If you run the numbers, as stars get further away from the
Researchers studied cannibalism among commonly-found moths to test an evolutionary principle. The scientists concluded that moths with more sibling interaction were less selfish. The principle applies to humans and other animals. A common moth, found in pantries, could explain a crucial link between society and selfishness, according to a new study. Researchers showed that an increase in sibling

It is a theory decried by many scientists and rejected as "extremely unlikely" by at least one World Health Organization international expert. The former official, Dr. Robert Redfield emphasized that it was his opinion.
Scientists have tested a special vaccine intended to help the body fight brain cancers for the first time in humans. As detailed in a new paper published by the journal Nature , the team of researchers from the German Cancer Research Center (DFKZ) have created an early version of a vaccination that could trigger an immune response inside brain tumor tissues. Some usually incurable train tumors, c
American political discourse was not exactly harmonious five years ago, but over the course of Donald Trump's presidency, it corroded even further. What's called the national conversation is really just millions of people communicating with each other, and if you could tune out all the yelling, you might be able to detect some of the silences that have arisen when two people stopped talking entir
The extinct human lineage nicknamed "the hobbit" may not be a distant relative of modern humans as previously thought. Instead, hobbits may be members of the mysterious close relatives of modern humans known as Denisovans.
W hy did so many Republicans— 147 of them —object to the Electoral College result on January 6? Most voted to overturn the election out of fear. Not fear of the angry mob that had invaded the Capitol hours earlier, but fear of the voters who might threaten their reelection––specifically in their next party primary. This is the "primary problem" in the U.S. political system today: A small minority
The idea of the atom goes as far back as the ancient Greek philosopher Democritus in about 400 B.C.E. This led to his "theory of eidôla " to explain how our minds create the illusion of reality. Democritus was one of the first determinists, arguing that a world made only of atoms and controlled by the laws of physics left no room for free will. Philosophers love "The Matrix". It's the perfect int

Astronomers have investigated orbital and stellar parameters of an eclipsing binary known as 2M06464003+0109157. Results of the study shed more light on the nature of this peculiar system. The findings were presented in a paper published March 18 on the arXiv pre-print repository.
In order to truly end the pandemic, it will be essential to get vaccines to all parts of the world. The first part of that challenge involves boosting the supply and securing doses for all , but even if enough vaccines become ready, the next hurdles are storage and distribution. For some covid vaccines, that means shuttling through what's known as the "cold chain," a series of very well chilled e
President Joe Biden is promising the world that " America is back ," but his effort to reclaim global leadership shouldn't come at the expense of the country's closest friends. At a NATO foreign ministers' meeting last week, Secretary of State Antony Blinken sharply criticized Germany's efforts to get more natural gas from Russia through a pipeline project known as Nord Stream 2. The president, B
A Disturbing Trend In a move that'll have you saying, "Why the hell wasn't this already a thing," YouTube is putting a ban on staged animal rescue videos. The social media platform told The Times that there is a "disturbing trend" of videos showcasing animals put in deadly situations, only to have them be "rescued" by the filmmakers. Videos of these fake animal rescues include puppies being const

Earlier this month, the United States promised to send Canada and Mexico a total of 4 million doses of the AstraZeneca vaccine, which is not yet being used to inoculate Americans against COVID-19. The commitment of 2.5 million vaccines to Mexico represents the largest single pledge of vaccine doses from one country to another so far in this crisis. Those doses are going to a neighbor in great nee
In a Massachusetts home, a family gathers around the kitchen table. The parents tune in to the device that sits at the head of the table. Moments later, a cheery voice quiets the chatter as the whole family settles in to listen. No, this isn't a scene from the golden era of the wireless. This is the Daniels home during covid-19 lockdown, and the focus of the family's attention is Yoto , an audio
SO FAR, MORE THAN 87 MILLION AMERICAN adults have gotten at least one dose of a COVID-19 vaccine — and over half of those folks are already fully vaccinated. That means that for a rapidly growing chunk of the population, there's finally a light at the end of the tunnel, meaning the most restrictive aspects of life under lockdown may soon come to an end. That doesn't mean that the pandemic will mi
Secret Code On Monday, the US Strategic Command — that's the agency that controls the military's nukes — tweeted a bizarre string of characters that left the internet confused and perhaps mildly concerned. Not that there's anything wrong with occasionally firing up Twitter and broadcasting ";l;;gmlxzssaw" to the world, of course. But Stratcom helps oversee and manage the country's nuclear arsenal
Like many countries, China has a health care problem. Changing demographics and lifestyles mean demand for health care is outstripping growth in medical resources and its cost is rising faster than the insurance premium. With 250 million people over the age of 60, the world's most populous country is ageing. Diseases associated with more affluent societies, such as cardiovascular conditions and d
An international team of astronomers has carried out a comprehensive radio and X-ray monitoring of a black hole X-ray binary known as MAXI J1348–630. The observational campaign provided important insights into the evolution of the source's compact and transient jets. The study was presented in a paper published March 22 on arXiv.org.
A team of scientists from Heriot-Watt University has created an underwater observatory in the Faroe-Shetland Channel—and found its waters are teeming with oil-eating bacteria that could help deal with future oil spills.
The promising field of spintronics seeks to manipulate electron spin to make a new breed of small and low-power electronic devices. A recent study used Argonne's Advanced Photon Source to bring the widespread use of spintronics closer to reality.
In preparation for cell division, cells need to replicate the DNA that they contain. A team of researchers from TU Delft, collaborating with investigators from the Francis Crick Institute in London, has now shown that the protein building blocks involved in the initial steps of DNA replication are mobile but reduce their speed at specific DNA sequences on the genome. Their findings, which were pub
The news: A "real-world" study of 3,950 people in six states found that two doses of the Pfizer-BioNTech and Moderna vaccines cut the risk of infection by 90%. The findings are broadly in line with the 95% and 94% efficacy that the Pfizer and Moderna vaccines showed, respectively, in their clinical trials. The details: The US Centers for Disease Control and Prevention study recruited essential wo
Two separate clusters of UK variant spread in Brisbane when unvaccinated health workers contracted coronavirus The Queensland hospital system was already "stressed" before the latest Covid outbreak partly because everyone with the virus is moved from hotel quarantine into hospital, but not all hospital workers have been vaccinated yet, experts say. There are now two separate clusters of the infec
Our colleagues from The age of extinction , Phoebe Weston and Patrick Greenfield, are back with two new episodes. We often talk as if we know what species exist in the world – but we don't.

Prolonged and potentially destabilizing water shortages will become commonplace in Jordan by 2100, new research finds, unless the nation implements comprehensive reform, from fixing leaky pipes to desalinating seawater. Jordan's water crisis is emblematic of challenges looming around the world as a result of climate change and rapid population growth.
Physical activity is important in preventing heart and blood vessel disease in young people so long as they don't undertake very strenuous activity on days when air pollution levels are high, according to a nationwide study of nearly 1.5 million people published in the European Heart Journal.
A first-of-its-kind instrument that samples smoke from megafires and scans humidity will help researchers better understand the scale and long-term impact of fires—specifically how far and high the smoke will travel; when and where it will rain; and whether the wet smoke will warm the climate by absorbing sunlight.
Bullying at boarding schools has a negative impact on students' emotional health, but for male students, having a school staff member to rely on for support may mute the harmful effects of bullying, according to a new study. Support networks did not have the same effect for female students, the researchers say.
The recommendations are clear: physical activity is good for mental health. But it also depends on how varied it is. That's what a new study shows, pointing to one of the reasons why well-being suffers during the pandemic.
Derek Lowe Here's an ingenious new detection technique for biomolecules that builds on a number of reports over the last few years. People have been working on electrochemical detectors using DNA constructs on electrode surfaces, but this would appear to be an improved way to do it. A team from Toronto reports using a "molecular pendulum" attached to an electrode surface, as shown at right. An an
Scientists at MIPT have found a possible explanation for the anomalously fast release of gas from nuclear fuel. Supercomputer simulations have uncovered an unexpected mechanism for accelerating the escape of gas bubbles from the uranium dioxide crystal matrix to the surface. The result points the way to eliminate the paradoxical discrepancy of several orders of magnitude between existing theoretic
This image taken with the NASA/ESA Hubble Space Telescope features NGC 7678—a galaxy with one particularly prominent arm, located approximately 164 million light-years away in the constellation of Pegasus (the Winged Horse).
The SwRI-led Ultraviolet Spectrograph (UVS) orbiting Jupiter aboard NASA's Juno spacecraft has detected new faint aurora features, characterized by ring-like emissions, which expand rapidly over time. SwRI scientists determined that charged particles coming from the edge of Jupiter's massive magnetosphere triggered these auroral emissions.
New updates on the conservation status of sharks and rays released today by the International Union for Conservation of Nature (IUCN) show that 39 additional species are now facing a risk of extinction in the wild. This takes the total of all sharks and rays categorized as Vulnerable, Endangered, or Critically Endangered to 355.
Great apes do not pass on their behavior to the next generation. Unlike humans, they do not copy the specific knowledge of those around them, instead learning it anew in each generation. This is shown in a study by Dr. Alba Motes-Rodrigo and Dr. Claudio Tennie of the "Tools and Culture in Early Hominins" research group at the University of Tübingen. "Metaphorically speaking, apes constantly have t
For over a decade, a mining company allowed scientists to explore one of New Zealand's most spectacular fossil sites. When the site changed hands, it seemed the fossils would all be crushed to dust. But New Zealanders rallied behind the fossils. Has public resistance saved the site for science?
Zombies are supposed to be capable of asking any question about the nature of experience. It's worth wondering, though, how a person or machine devoid of experience could reflect on experience it doesn't have.

Why do some people with cold sores around their lips experience painful lesions, while others have no symptoms at all, yet still spread the virus? A new study finds that these differences could be due to variations in the way certain strains of herpes simplex (HSV-1) — the virus that causes cold sores, as well as genital herpes — activate gene expression in neurons.
Girlhood, Melissa Febos writes in her new essay collection of the same name, is "a darker time for many than we are often willing to acknowledge." The overall impression she creates is a collage of discomfitingly familiar rites of passage, all distinct and yet all tied together by a thread of learned self-abnegation. The book reads at moments like a meme built from various half-buried abuses and

Last spring, Jared Kushner predicted that the coronavirus pandemic would soon end and that the United States would be " really rocking again " by July. Some critics saw his statement, which proved so fatally wrong, as a form of deceit. I saw evidence of something more pitiful: Kushner had fallen prey to optimism bias and availability bias. Optimism clouded his judgment. He wanted things to be bet
A new type of universal computer memory – ULTRARAM™ – has taken a step closer towards development with a successful experiment.

While Western countries spar over access to the world's vaccine supply, China and Russia have been busy giving away theirs. This distribution of millions of doses, either for free or cheaply, to low- and middle-income nations has been met with skepticism by leaders in the United States and Europe, many of whom have raised concerns over the safety of the jabs, as well as Beijing's and Moscow's mot
Astronomers found a number of stellar eggs containing baby stars around the center of the Milky Way using the Atacama Large Millimeter/submillimeter Array (ALMA). Previous studies had suggested that the environment there is too harsh to form stars. These findings indicate that star formation is more resilient than researchers thought.
Scientists have developed a diagnostic test, which makes use of CRISPR, that can detect the virus that causes COVID-19 even after it has gone through mutations. Since viruses have the ability to evolve over time, a diagnostic test robust against potential mutations is a crucial tool for tracking and fighting the pandemic.
A research group developed a game application for smartphones that estimates the possibility of carpal tunnel syndrome with machine learning. The program acquires the trajectory of the thumb during a game play in 30 sec — 1 minute, and detects the possibility of the disease.
About 50km outside South Africa's biggest city, Johannesburg, lies one of the most important sites in human prehistory: the Cradle of Humankind.

Humans are simply not adapted to space. We evolved in 1G, the amount of gravity near the surface of the Earth, and are well suited to that environment. Spending a lot of time in microgravity, such as aboard the ISS, has a number of physiological effects. Now that some astronauts have been spending long periods of time aboard the ISS, researchers have been better able to understand these effects.
Scientists discover one of the first black holes of its kind. Intermediate mass black holes (100 to 100,000 times the mass of the sun) have only been directly detected once before (LIGO, last year). They form an important link between the smaller black holes left behind after the deaths of stars, and the supermassive black holes which lurk in the hearts of every galaxy. The astrophysicists also fi
In less than three years, astronauts will return to the moon for the first time since the Apollo Era. As part of the Artemis Program, the purpose is not only to send crewed missions back to the lunar surface to explore and collect samples.

Climate labels informing us of a meat product's carbon footprint cause many people to opt for climate-friendlier alternatives. This applies to people who are curious about a product's carbon footprint, as well as to those who actively avoid wanting to know more.
The young doctor was desperate. 'I need to talk to my patients,' she said, 'and give them time to ask questions." "Some of them are foreign-born and struggle with the language, and all of them are in distress! But I hardly have the time to explain the essentials to them. There's all the paperwork, and we're constantly understaffed.' Such grievances have become sadly familiar – not only in medicin
One specific protein may be a master regulator for changing how cancer cells consume nutrients from their environments, preventing cell death and increasing the likelihood the cancer could spread, a study has shown.
It's not uncommon for people who experience a concussion to have moderate to severe headaches in the weeks after the injury. A new study has found a combination of two drugs, both common anti-nausea medications, given intravenously in the emergency room may relieve those headaches better than a placebo.
A combination of esophageal brushing and extensive genetic sequencing of the sample collected can detect chromosome alterations in people with Barrett's Esophagus, identifying patients at risk for progressing to esophageal cancer, according to a new study.
Scientists have highlighted the key role of a protein called paxillin, which enables cells to perceive their environment and anchor at the right place with the help of cellular 'crampons'. Indeed, without functional paxillin, the cell is unable to attach properly and slips continuously. These results shed new light on how cells adhere or migrate, mechanisms essential to the good functioning of our

New fundamental physics research provides insights on the process of diffusion in complex systems such as living organisms. This new theoretical framework has broad implications for active surfaces, such as ones found in bacterial biofilms, active coatings, and pathogen-clearance mechanisms for human health.
The creation of genes with new functions is a major driver of developmental innovation in all living organisms. How these genes acquire new functions over evolutionary time scales, however, is unclear.
When I was a teenager, I volunteered in the rainforest exhibit at an aquarium. A few times a week, we'd get a phone call from someone looking to donate a pet that they could no longer care for. Mostly turtles and frogs. The occasional parrot. Once, a retired dancer wanted to find a new home for two boa constrictors that had been part of her act.
The vast majority of the world's largest meat and dairy companies have not made an explicit commitment to achieving net-zero emissions by 2050, finds a new analysis by researchers at New York University.
While bionic devices are very safe, there has been no standard test for moisture leakage into the devices – until now. Researchers say a standard test will be increasingly important as bionic implants become more common.
EU imports of products including palm oil, soybeans, and beef contribute significantly to deforestation in other parts of the world. In a new study, researchers evaluated over a thousand policy proposals for how the EU could reduce this impact, to assess which would have the largest potential to reduce deforestation – while also being politically feasible.
Scientists have decoded the genomes of the deep-sea clam (Archivesica marissinica) and the chemoautotrophic bacteria (Candidatus Vesicomyosocius marissinica) that live in its gill epithelium cells. Through analysis of their genomic structures and profiling of their gene expression patterns, the research team revealed that symbiosis between the two partners enables the clams to thrive in extreme de
Limited water availability, population growth, and climate change have resulted in freshwater crises in many countries. Jordan's situation is emblematic, compounded by conflict-induced population shocks. Integrating knowledge across hydrology, climatology, agriculture, political science, geography, and economics, we present the Jordan Water Model, a nationwide coupled human–natural-engineered syst
Climate change is altering the world we share with all living things. But it's surprisingly difficult to single out climate change as an extinction threat for any one particular species protected under the Endangered Species Act. A new analysis of population data shows that climate change represents a specific extinction threat for an endangered coastal lupine plant.
Younger trees take up and release less water than mature trees 10 years or older, researchers from North Carolina State University found in a new study that tracked how water moves through wetland pine forests near the North Carolina coast.
Six women of Asian descent were among eight people tragically killed in a targeted shooting on March 16 in Atlanta. The initial denial by the Atlanta police that this was a hate crime, along with some news reports highlighting the offender's version of the incident, evoked a swift reaction by communities all over North America. Many spoke of the invisibility of anti-Asian racism.
In the Arctic, climate change and pollution are the biggest threats to top predators like narwals. Studying the animals' tusks reveals that diet and exposure to pollution have shifted over the past half century in response to sea-ice decline. Human emissions have also led to a sharp rise in the presence of mercury in recent years, according to an international team of researchers.
Nitrogen dioxide, an air pollutant emitted by fossil fuel-powered cars and gas-burning stoves is not only bad for the climate—it's bad for our health. Long-term exposure to NO2 has been linked to increased heart disease, respiratory diseases such as asthma, and infections.
Despite the enormous amount of research over the decades into lasers and their applications, there have been few ways to accurately, efficiently, and directly observe fine details of their interactions with materials. For the first time, researchers have found a way to acquire such data from a production laser using low-cost equipment that could vastly improve the accuracy of items cut or etched w
Until now, historians have treated accounts of extreme weather events that might indicate climate change, or more specifically an increase in rainfall, with suspicion. Too many purely cultural factors, they argue, might have influenced one author or another to write about rains, droughts or floods.
Nanowires are vital components for future nanoelectronics, sensors, and nanomedicine. To achieve the required complexity, it is necessary to control the position and growth of the metal chains on an atomic level. A research team has introduced a novel approach that generates precisely controlled, helical, palladium-DNA systems that mimic the organization of natural base pairs in a double-stranded
Our linear model of time may be holding back scientific progress. Spacekime theory can help us better understand the development of diseases, financial and environmental events, and even the human brain. This theory helps us better utilize big data, develop AI, and can even solve inconsistencies in physics. We take for granted the western concept of linear time. In ancient Greece, time was cyclic
New modeling identifies country-specific human and human-influenced environmental factors associated with disease outbreaks. A country's land area, human population density, and area of forest are associated with zoonotic diseases, like COVID-19. Human development index, average annual temperature, and health expenditure predict other kinds of disease.
A reproducibility crisis is ongoing in scientific research, where many studies may be difficult or impossible to replicate and thereby validate, especially when the study involves a very large sample size. Now researchers have developed a statistical tool that can accurately estimate the replicability of a study, thus eliminating the need to duplicate the work and effectively mitigating the reprod
Researchers have revealed the necessary conditions for the robust transport of entangled states of two-photon light in photonic topological insulators, paving the way the towards noise-resistant transport of quantum information.
A doctoral student has identified a long-overlooked pattern in how plants evolved their equivalent of lungs — tiny pores on the surfaces of leaves called stomata. Using specialized imaging techniques and a plant species not often found in laboratories, researchers say this discovery reveals a key difference in the evolution of plants that live on land versus those that can grow in water.
Because Taspase 1 dysregulation is increasingly implicated in the genesis and metastasis of various cancers, it has become an attractive candidate for drug development. But before this can happen, researchers will need a highly detailed blueprint of the structure of this protease. In a new study appearing in the Cell Press journal Structure, researchers from Arizona State University describe their
When stars are born, large clouds of gas and dust form that are known as circumstellar discs. Research by Ph.D. candidate Francisca Concha-Ramírez shows that strong radiation from neighboring stars soon evaporates the dust in these discs, which can prevent planet formation at an early stage. Ph.D. defence on 6 April.
In the summer of 2020, hundreds of Larch Budmoths were observed on Vize Island, in the Russian High Arctic, likely transported over 1,200 km by air currents from Siberia. This is the first and only terrestrial invertebrate to ever be discovered on the island. This finding could mean that Vize island is less isolated from insect migrants than was commonly thought.
The ongoing COVID-19 pandemic has significantly reduced the number of people willing to fly due to safety concerns, and to ease fears, some airlines have opted to leave middle seats open to increase the amount of space for social distancing.
Adrop of food coloring slowly spreading in a glass of water is driven by a process known as diffusion. While the mathematics of diffusion have been known for many years, how this process works in living organisms is not as well understood.
A new peer review paper offers one of the most comprehensive reviews of advancements to come in contact lenses, catapulting the commonly-used medical device to applications well beyond refractive error correction, e.g., disease detection and treatment, theranostics and shape shifting for real-time vision enhancement.
The childhood memories we retain most searingly tend to involve shame. When I was 6, after being chided twice for talking too loudly during lunch, I was made to stand in the cafeteria by myself until the other kids finished their food. I can't even type that sentence without flushing at how conspicuously bad I felt, and how alone. Humiliation is a kind of trauma; when we experience it, our nervou
The longest corridor in ESA's largest establishment was turned into a test site for one of the Agency's most ambitious future missions, Proba-3. The two satellites making up this mission will line up so that one casts a shadow onto the other, revealing inner regions of the Sun's ghostly atmosphere. But such precision formation flying will only be possible through a vision-based sensor system allow
Editor's Note: Every Tuesday, Abby Freireich and Brian Platzer take questions from readers about their kids' education. Have one? Email them at email@example.com. Dear Abby and Brian, Our 11-year-old son has been in virtual learning since March 2020. It's been a daily struggle, to say the least. He is an only child who is incredibly social, and we can see the isolation taking its toll on h
Many experts believe that the Moon was formed when a protoplanet named Theia crashed into the Earth 4.5 billion years ago. One flaw in the theory has been that there's no remaining sign of Theia. New research suggests that Theia's mantle was subsumed by Earth and that large anomalous blogs of rock deep within the Earth are its remains. They're called "large low-shear-velocity provinces" (LLSVPs),
A team of researchers has developed a new early warning system for vehicles that uses artificial intelligence to learn from thousands of real traffic situations. The results show that, if used in today's self-driving vehicles, it can warn seven seconds in advance against potentially critical situations that the cars cannot handle alone – with over 85% accuracy.
At the start of March, NASA's Curiosity Mars rover began approaching an impressive rock formation that scientists dubbed "Mont Mercou," a nickname taken from a mountain in France. Standing about 20 feet (6 meters) tall, the outcrop is captured in all its majesty in a new selfie, as well as in a pair of panoramas that offer a 3D view. The selfie shows Curiosity in front of Mont Mercou with a new dr
