Researchers have discovered a universal mathematical formula that can describe any bird's egg existing in nature -- a significant step in understanding not only the egg shape itself, but also how and why it evolved, thus making widespread biological and technological applications possible.

Cutting 20 percent of sugar from packaged foods and 40 percent from beverages could prevent 2.48 million cardiovascular disease events (such as strokes, heart attacks, cardiac arrests), 490,000 cardiovascular deaths, and 750,000 diabetes cases in the U.S. over the lifetime of the adult population, according to a new study.

A new analysis of 2.5-billion-year-old rocks from Australia finds that volcanic eruptions may have stimulated population surges of marine microorganisms, creating the first puffs of oxygen into the atmosphere. This would change existing stories of Earth's early atmosphere, which assumed that most changes in the early atmosphere were controlled by geologic or chemical processes.

A human space mission would be viable if it doesn't exceed four years, an international research team concludes in new research.

A new class of exoplanet very different to our own, but which could support life, has been identified by astronomers, which could greatly accelerate the search for life outside our Solar System.

Researchers have found that blood flow in the brain capillaries, which is important for oxygen/nutrient delivery and waste removal, was increased during rapid eye movement sleep in mice. Adenosine A2a receptors might be at least partially responsible for this increased blood flow. These findings bring new hope for understanding the function of sleep and developing treatments for neurodegenerative diseases that involve the buildup of waste products in the brain, such…

There's been an age-old question going back to Darwin's time about the relationships among the world's five living rhinoceros species. One reason answers have been hard to come by is that most rhinos went extinct before the Pleistocene. Now, researchers have helped to fill the gaps in the rhino evolutionary family tree by analyzing genomes of all five living species together with the genomes of three ancient and extinct species.

At certain sites in the Grand Canyon, more than one billion years' worth of rocks have gone missing from the geologic record. Scientists are trying to figure out why.

Scientists have unraveled the enigma of inheritance of coat color patterns in dogs. The researchers discovered that a genetic variant responsible for a very light coat in dogs and wolves originated more than two million years ago in a now extinct relative of the modern wolf.

A new kind of neural interface system that coordinates the activity of hundreds of tiny brain sensors could one day deepen understanding of the brain and lead to new medical therapies.

A new study has uncovered the engineering secrets behind what makes fish fins so strong yet flexible. The research could one day lead to new designs for robotic surgical tools or even airplane wings that change their shape with the push of a button.

Global warming begets more, extreme warming, new paleoclimate study finds. Researchers observe a 'warming bias' over the past 66 million years that may return if ice sheets disappear.

Scientists are observing changes in the Earth's climate in every region and across the whole climate system, according to the latest IPCC Report. Many of the changes observed in the climate are unprecedented in thousands, if not hundreds of thousands of years, and some of the changes already set in motion -- such as continued sea level rise -- are irreversible over hundreds to thousands of years.

A major Atlantic ocean current -- the Atlantic Meridional Overturning Circulation, or AMOC -- may have been losing stability in the course of the last century, according to new research. A potential collapse of this ocean current system could have severe consequences.

Eating a plant-centered diet during young adulthood is associated with a lower risk of heart disease in middle age, according to a long-term study with about 30 years of follow-up. A separate study with about 15 years of follow-up found that eating more plant-based foods that have been shown to lower cholesterol, called the 'Portfolio Diet', is associated with lower risk of cardiovascular disease in postmenopausal women.

New research has revealed the solution to Jupiter's 'energy crisis', which has puzzled astronomers for decades. Astronomers have created a detailed global map of the gas giant's upper atmosphere, confirming that Jupiter's powerful aurorae are responsible for delivering planet-wide heating.

Scientists have discovered evidence that giraffes are a highly socially complex species.

Astronomers have uncovered evidence of water vapor in the atmosphere of Jupiter's moon Ganymede. This water vapor forms when ice from the moon's surface sublimates -- that is, turns from solid to gas. Astronomers re-examined Hubble observations from the last two decades to find this evidence of water vapor.

Researchers have discovered that spontaneous impulses of dopamine, the neurological messenger known as the brain's 'feel good' chemical, occur in the brain of mice. The study found that mice can willfully manipulate these random dopamine pulses for reward.

Researchers have recently identified a DNA region known as VNTR2-1 that appears to drive the activity of the telomerase gene, which has been shown to prevent aging in certain types of cells. Knowing how the telomerase gene is regulated and activated and why it is only active in certain cell types could someday be the key to understanding how humans age and how to stop the spread of cancer.

Researchers have been able to use seismic data to look inside Mars for the first time. They measured the crust, mantle and core and narrowed down their composition.

As a newborn mammal opens its eyes for the first time, it can already make visual sense of the world around it. But how does this happen before they have experienced sight?

Scientists have shown that cockatoos can learn from each other a unique skill -- lifting garbage bin lids to gather food. The research confirms that cockatoos spread this novel behavior through social learning.

Scientists have successfully reversed age-related memory loss in mice and say their discovery could lead to the development of treatments to prevent memory loss in people as they age.

Scientists who study glacier ice have found viruses nearly 15,000 years old in two ice samples taken from the Tibetan Plateau in China. Most of those viruses, which survived because they had remained frozen, are unlike any viruses that have been cataloged to date.

Researchers have found a low-cost way to solve one half of the water-splitting equation to produce hydrogen as clean energy -- using sunlight to efficiently split off oxygen molecules from water. The finding represents a step forward toward greater adoption of hydrogen as a key part of our energy infrastructure.

New models of neutron stars show that their tallest mountains may be only fractions of millimeters high, due to the huge gravity on the ultra-dense objects.

Investigating how climate affects intense rainstorms across Europe, climate experts have shown there will be a significant future increase in the occurrence of slow-moving intense rainstorms. The scientists estimate that these slow-moving storms may be 14 times more frequent across land by the end of the century. It is these slow-moving storms that have the potential for very high precipitation accumulations, with devastating impacts, as we saw in Germany and…

Researchers have successfully developed a 'speech neuroprosthesis' that has enabled a man with severe paralysis to communicate in sentences, translating signals from his brain to the vocal tract directly into words that appear as text on a screen.

A decade after scientists discovered that lab rats will rescue a fellow rat in distress, but not a rat they consider an outsider, new research pinpoints the brain regions that drive rats to prioritize their nearest and dearest in times of crisis. It also suggests humans may share the same neural bias.

A team of physicists has developed a special type of quantum computer known as a programmable quantum simulator capable of operating with 256 quantum bits, or 'qubits.'

Researchers discovered that most bacteria in the gut microbiome are heritable after looking at more than 16,000 gut microbiome profiles collected over 14 years from a long-studied population of baboons in Kenya's Amboseli National Park. The team also found that several of the microbiome traits heritable in baboons are also heritable in humans.

The ability to focus on where we will be in the near future, rather than where we are at present, may be a key characteristic of the mammalian brain's built-in navigation system, suggests a new study. The researchers wirelessly tracked the brain activity of flying Egyptian fruit bats, finding that neural activity in the bats' hippocampuses more strongly represented future locations than current locations.

Scientists map the part of the brain that 'links' similar objects, leading to new insights about how the brain processes information out of context.

New research shows radioactive molecules are sensitive to subtle nuclear phenomena. The molecules might help physicists probe violation of the most fundamental symmetries of nature, including why the universe contains relatively little antimatter.

A study concludes that known geochemical processes can't explain the levels of methane measured by the Cassini spacecraft on Saturn's icy moon. While the paper by no means suggests that life exists on Enceladus, the results would be consistent with microbial activity similar to that known to occur at hydrothermal vents in Earth's oceans. 

Flies have discriminating taste. Like a gourmet perusing a menu, they spend much of their time seeking sweet nutritious calories and avoiding bitter, potentially toxic food. But what happens in their brains when they make these food choices? Researchers discovered an interesting way to find out. They tricked them.

Neuroscientists have demonstrated in new research that dopamine plays a key role in how songbirds learn complex new sounds.

A new study disputes the prevailing hypothesis on why Mercury has a big core relative to its mantle. For decades, scientists argued that hit-and-run collisions blew away much of Mercury's rocky mantle and left the big, dense, metal core inside. But new research reveals that collisions are not to blame -- instead, the density, mass and iron content of a rocky planet's core is influenced by its distance from the…

In COVID-19 patients whose symptoms were mild, researchers found that they were more likely than sicker patients to have signs of prior infection by similar, less virulent coronaviruses.

Current rates of plastic emissions globally may trigger effects that we will not be able to reverse, argues a new study. According to the authors, plastic pollution is a global threat, and actions to drastically reduce emissions of plastic to the environment are 'the rational policy response.'

A new species of the extinct genus Vishnuonyx has been identified from the 11.4-million-year-old lower jaw found at the Upper Miocene site of Hammerschmiede in the Allgäu region of Germany. Vishnuonyx is an extinct genus of mid-sized otters (10-15 kg) that lived between 14 and 12.5 million years ago in the major rivers of Southern

Paleontologists in China have identified a new species of pengornithid enantiornithine bird with a pair of elaborate tail feathers. Enantiornithes are the most successful group of Mesozoic birds, arguably representing the first global avian radiation. They are known exclusively from the Cretaceous period, predominantly from fossils discovered in Asia, and commonly resolved as the sister

The intermediate-mass black hole in question was caught in the act of swallowing a star, called a tidal disruption event. Dubbed 3XMM J215022.4-055108, the event occured in a star cluster associated with a lenticular galaxy at distance of almost 800 million light-years away. “The fact that we were able to catch this intermediate-mass black hole

Paleontologists have discovered tracks and trackways of newborns, calves and juveniles attributed to straight-tusked elephants (Palaeoloxodon antiquus) at the Upper Pleistocene site in Huelva, Spain. The straight-tusked elephant is a species of giant elephant that lived between 1.5 million and 100,000 years ago. This animal with very wide heads and extremely long tusks is among

Until now, it has been unclear what created gamma-rays that appear in patches of seemingly ‘empty sky.’ “It’s a significant milestone to finally discover the origins of this gamma-ray emission, solving a mystery of the Universe astronomers have been trying to decipher since the 1960s,” said Dr. Matt Roth, an astronomer in the Research School

Using high-resolution images from NASA’s Mars Reconnaissance Orbiter, planetary scientists have discovered 4-billion-year-old layered deposits containing minerals consistent with altered volcanic ash throughout a region of northern Mars called Arabia Terra. They estimate that the volcanic ash observed in this region is the result of between 1,000 and 2,000 individual explosive eruptions over 500 million

Some unexplained results from the XENON1T dark-matter detector — a 1,300-kg vat of super-pure liquid xenon shielded from cosmic rays in a cryostat submerged in water deep 1.5 km beneath the Gran Sasso mountains of Italy — may have been caused by dark energy particles produced in a region of the Sun with strong magnetic

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have found thousands of dense gas clumps but, surprisingly, no star formation, in a circumnuclear disk around Sagittarius A*, the 4-million-solar-mass black hole at the center of our Milky Way Galaxy. Every large galaxy has a central supermassive black hole that dominates and is fed by nearby

A new species of large-sized penguin being named Kairuku waewaeroa has been identified from the fossilized bones found in Kawhia Harbour on the North Island of New Zealand. Kairuku waewaeroa roamed Earth during the Oligocene epoch, between 27 and 35 million years ago. “The penguin is similar to the Kairuku giant penguins first described from

Entomologists have described a new species in the window fly genus Scenopinus from Finland. Window flies are members of Scenopinidae, a small family of primitive flies belonging to the superfamily Asiloidea. They have a cosmopolitan distribution, with more than 420 described species in 25 genera. The greatest diversity is in the arid regions of the

When two substances are brought together, they will eventually settle into a steady state called the thermodynamic equilibrium. In new research, a team of physicists at Aalto University wanted to disrupt this state to see what happens; they subjected combinations of oils with different dielectric constants and conductivities to an electric field. “When we turn

A series of previously unreported hand and foot impressions from the Tibetan Plateau dates to between 169,000 and 226,000 years ago (middle Pleistocene period) and may be the oldest work of art. “The question is: What does this mean? How do we interpret these prints? They’re clearly not accidentally placed,” said co-author Dr. Thomas Urban,

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have mapped out 18 organic and inorganic molecules in protoplanetary disks around five young stars: IM Lup, GM Aur, AS 209, HD 163296, and MWC 480. The new ALMA maps reveal that the chemicals in protoplanetary disks are not located uniformly throughout each disk; instead, each disk

According to a new study in mice, a probable cause of Alzheimer’s disease is the leakage from blood into the brain of fat-carrying particles transporting toxic proteins. “We identified the probable ‘blood-to-brain pathway’ that can lead to Alzheimer’s disease, the most prevalent form of dementia globally,” said study’s senior author Professor John Mamo, director of

About 66 million years ago, a massive asteroid crashed into Earth near the site of the small town of Chicxulub in what is now Mexico. The impact eradicated roughly 75% of the animal and plant species on Earth, including whole groups like non-avian dinosaurs and ammonites. New research from the Universities of Bath, Bristol, and

Impact bombardment has played a significant role in the evolution of the Earth-Moon system. However, it is suggested from different perspectives, including impact crater dating, asteroid dynamics, lunar samples, impact basin-forming simulations, and lunar evolution modeling, that the Moon could be missing evidence of its earliest cratering record. New research shows that many ancient impact

Using spectral data from the Sloan Digital Sky Survey (SDSS), the Chandra Source Catalog 2.0, and the Chandra COSMOS Legacy survey, astronomers have found that X-ray and ultraviolet luminosities of quasars are so tightly correlated that these objects can be used as new ‘standard candles’ to help determine cosmic distances and probe other fundamental cosmological

A new genus and species of palaeoscolecid worm has been identified from two specimens found in the Burgess Shale-type deposits in Utah, the United States. Palaeoscolecida is a group of extinct ecdysozoan worms that existed from the Ealy Cambrian to the Late Silurian period. These ancient creatures were narrow and long, up to tens of

A new community-dwelling study from Sweden suggests that the lunar cycle affects sleep in humans, with more pronounced sleep alterations in men than women. “Both the new and full moons represent significant turning points during the lunar cycle,” said lead author Dr. Christian Benedict, a researcher in the Department of Neuroscience at Uppsala University, and

A new study published in the journal Scientific Reports provides empirical evidence for deliberate self-care tooling in a species of bird. “Most reports of tooling in birds revolve around foraging,” said study lead author Amalia Bastos, a Ph.D. candidate in the School of Psychology at the University of Auckland, and colleagues from the University of
