Los Angeles County supervisors voted unanimously Wednesday to phase out oil and gas drilling and ban new drill sites in the unincorporated areas of the nation's most populous county.

SpaceX aimed to blast a billionaire into orbit Wednesday night with his two contest winners and a health care worker who survived childhood cancer.

Nuclear war would cause many immediate fatalities, but smoke from the resulting fires would also cause climate change lasting up to 15 years that would threaten worldwide food production and human health, according to a study by researchers at Rutgers University, the National Center for Atmospheric Research and other institutions.

Federal officials have approved a plan that calls for cutting nontribal salmon fishing along the West Coast when the fish are needed to help the Northwest's endangered killer whales.

A textile-based implant containing cartilage derived from stem cells reduced pain and restored hip joint function to baseline levels in a study of dogs with symptoms of moderate osteoarthritis. The study, led by researchers at North Carolina State University, Washington University in St. Louis and Cytex Therapeutics Inc., could be a significant first step toward preventative, less invasive joint...

A new landmark study of over 300 sharks found that some species are extremely resilient to the stress of being caught and released in commercial longline fisheries while other species are much more likely to die.

Parents are more influenced by the atmosphere and how caring staff are than academic educational standards or the curriculum when choosing a special educational needs school, a study shows.

Researchers at Oregon State University have developed a method for forecasting up to three weeks in advance the locations where a distinct population of New Zealand blue whales is most likely to occur.

Children who have not committed a crime are likely to be admitting guilt and accepting cautions just to avoid prosecution, a new report warns.

Research on leadership has long recognized the importance of understanding how leaders are perceived, and past studies have used a variety of techniques to examine different aspects of leadership. In a new study, researchers developed a computational method to predict and identify the correlates of leadership perceptions. The researchers used the method to predict leadership perceptions for more...

Archeologists have long had a dating problem. The radiocarbon analysis typically used to reconstruct past human demographic changes relies on a method easily skewed by radiocarbon calibration curves and measurement uncertainty. And there's never been a statistical fix that works—until now.

Some volcanoes can produce eruptions so powerful they release oceans of dust and toxic gases into the air, blocking out sunlight and changing a planet's climate for decades. By studying the topography and mineral composition of a portion of the Arabia Terra region in northern Mars, scientists recently found evidence for thousands of such eruptions, or "super eruptions," which are the most violent...

Scientists have discovered how the Sardine Run, one of the world's biggest migration events, works.

When two substances are brought together, they will eventually settle into a steady state called thermodynamic equilibrium; examples include oil floating on top of water and milk mixing uniformly into coffee. Researchers at Aalto University in Finland wanted to disrupt this sort of state to see what happens—and whether they can control the outcome.

Devastating Australian wildfires released twice as much climate-warming C02 than previously thought—but also triggered vast algae blooms thousands of miles away that may have soaked up significant extra carbon, according to studies published Wednesday.

Neanderthals, our closest relatives, became extinct between 40,000 to 35,000 years ago. Since the discovery of the first Neanderthal fossil 165 years ago, scientists have learned more about Neanderthals—including their culture, sociality, ecology, diet, control of fire, production and use of tools, physiology, and even their genomic code—than about any other non-human hominin. Here, Spanish...

A new study, led by researchers at the University of Cambridge and reported in the journal Physical Review D, suggests that some unexplained results from the XENON1T experiment in Italy may have been caused by dark energy, and not the dark matter the experiment was designed to detect.

Often, the squeaky wheel, or at least the shiniest object, seems to get all the attention. In a new study led by PSI Research Scientist Eva Lilly, it is the inactive Centaurs that take center stage and illuminate why other Centaurs may be so flashy. Centaurs are icy objects out between the orbits of Neptune and Jupiter that in some cases display comet-like tails and jets. This somehow happens...

Coconut trees grow slowly and are difficult to clone. Scientists at KU Leuven and the Alliance multiplied seedlings faster and conserved coconut genetic resources for the long term. This will help to preserve coconut tree biodiversity and meet the increasing demand for coconuts and derived products. 

Looking down a hillside dotted with large stumps and nearly devoid of trees, a pair of retired U.S. Forest Service employees lamented logging policies they helped craft to deal with two harbingers of climate change—pine beetles and wildfires.

To realize precise diagnosis of early-stage cancer for effective treatment and better prognosis, high-resolution magnetic resonance imaging (MRI) is indispensable with the help of contrast agents. Iron-oxide-based T2 MR contrast agent (IOCA) is facing severe question of strong ferromagnetism and thereby weak T2 contrast ability. Although numerous efforts have been devoted to enhance the contrast...

Thousands of seabirds that wash up on Atlantic coasts every year could have been starved to death by cyclones that whip up "washing machine" waves, a new study says, with experts warning the phenomenon could worsen with climate change.

Researchers at McMaster University have developed a sophisticated new tool that could help provide early warning of rare and unknown viruses in the environment and identify potentially deadly bacterial pathogens which cause sepsis, among other uses.

The Australian summer of 2019–2020, also known as the "Black Summer," was characterized by a series of devastating wildfires. Researchers from VU University Amsterdam and SRON Netherlands Institute for Space Research have determined the amount of CO2 released by these fires using satellite data. The wildfires produced nearly twice as much CO2 as Australia's annual fossil fuel consumption. The...
