A new study of thousands of people reveals a wide range in the amount of water people consume around the globe and over their lifespans, definitively spilling the oft-repeated idea that eight, 8-ounce glasses meet the human body's daily needs. Differences in environment, body composition and activity level contribute to daily water turnover of as little as 1 liter and as much as 10 liters.

Researchers have shown -- for the first time -- that less intensively managed British grazed grasslands have on average 50% more plant species and better soil health than intensively managed grassland. The new study could help farmers increase both biodiversity and soil health, including the amount of carbon in the soil of the British countryside.

Earth is about 29% land and 71% oceans. How significant is that mix for habitability? What does it tell us about exoplanet habitability?

A research team has demonstrated that, in a population of macaque monkeys, females with a higher social status had younger, more resilient molecular profiles, providing a key link between the social environment and healthy brains.

A team of researchers with the Yellowstone Wolf Project at the Yellowstone Center for Resources, in Yellowstone National Park, in Wyoming, has found that wolves in the park who become infected with Toxoplasma gondii, a common parasite, are much more likely to become leaders of their pack. In their study, reported in the journal Communications Biology, the group analyzed data from studies of the...

The Correctional Service of Canada (CSC) recently ended its longstanding relationship with the meatpacking company, Wallace Beef.

The Very Large Telescope (VLT) at Cerro Paranal in northern Chile, is undoubtedly one of the premier ground-based observatories. But a new infrared instrument recently installed on the telescope has made the VLT even better.

The Plant Physiology and Biochemistry research team at the University of Konstanz has discovered previously unknown molecular mechanisms by which plants adapt to their environment—important basic knowledge in times of climate change

As UN climate talks close in Egypt and biodiversity talks begin in Montreal, attention is on forest restoration as a solution to the twin issues roiling our planet. Forests soak up atmospheric carbon dioxide and simultaneously create habitat for organisms. So far, efforts to help forests bounce back from deforestation have typically focused on increasing one thing—trees—over anything else.

An international team of astronomers has conducted a double-telescopic study of the zone where the Wow! signal originated and failed to detect any signal. In their paper published in Research Notes of the American Astronomical Society, the group describes their study and what they learned from it.

Fertilization of an egg by sperm is the beginning of new life. The maternal and paternal genetic information, that collectively store the body plan of the living being, are combined after fertilization.

The vast majority of vertebrate species living today, including humans, belong to the jawed vertebrate group. The development of articulating jaws during vertebrate evolution was one of the most significant evolutionary transitions from jawless to jawed vertebrates, taking place at least 423 million years ago. The lower and upper jaws were initially connected by the primary jaw joint. However,...

Global assessments of historical oyster reef distribution have estimated that over 85% of oyster reefs have been lost to overfishing and coastal development. In recent decades, enormous effort has been put into developing and implementing different methods for restoring oyster reefs globally.

Delegates at a global summit on trade in endangered species on Friday approved a plan to protect 54 more shark species, a move that could drastically reduce the lucrative and cruel shark fin trade.

Researchers from the University of St Andrews have shown for the first time that not only do wild chimpanzees tend to look like their family members, but also some relationships are easier to detect than others.

For anyone with arachnophobia, the only thing worse than finding a lone spider dangling in a doorway or resting on your rear-view mirror is finding a whole cluster. 

On Friday, November 18, a test using collisions of lead ions was carried out in the Large Hadron Collider (LHC) and provided an opportunity for the experiments to validate the new detectors and new data-processing systems ahead of next year's lead-lead physics run.

A look at history often provides some context for the present and might even inform the future, so it's not surprising two Penn State faculty members' review of Cold War-era print and television advertisements about flying saucers and UFOs prompted some themes—and one overarching business reality—that informs television and internet ads these days.

Andrew Nelson studies bioarchaeology, in part, because it allows him to understand how people lived thousands of years ago. And while he has traveled the world investigating ancient mummies, his latest adventure with King Tut is one for the ages.

A proposed measure in Switzerland would have made that country the first to ban medical and scientific experimentation on animals. It failed to pass in February 2022, with only 21% of voters in favor. Yet globally, including in the United States, there is concern about whether animal research is ethical.

Nurseries for new planets, protostellar disks are oblate swathes of gas and dust that rotate about newly formed stars. The Earth and the other planets in the solar system were birthed from such a disk.

Low-traffic neighborhoods (LTNs) reduce traffic and air pollution without displacing the problem to nearby streets, new research has shown.

Researchers from the Quadram Institute and the University of East Anglia have uncovered how resistance has helped drive the emergence of dominant strains of Salmonella. In addition to antimicrobial resistance, resistance to bacteriophages may give these bugs a boost, in the short-term at least.

Widespread corruption is preventing Asian countries from effectively implementing measures to reduce carbon dioxide (CO2) emissions that are known to contribute to global warming, new research suggests.
