Rocks the size of fridges have been tumbling from Mont Blanc as summer temperatures soar, scaring away many hikers from Western Europe's highest mountain.

California claims to know how much climate-warming gas is going into the air from within its borders. It's the law: California limits climate pollution and each year the limits get stricter.

Little snow cover and glaciers melting at an alarming rate amid Europe's sweltering heatwaves have put some of the most classic Alpine hiking routes off-limits.

More than 1,000 years after his death in what is now Poland, a European king whose nickname lives on through wireless technology is at the center of an archaeological dispute.

A Chinese booster rocket made an uncontrolled return to Earth on Saturday, leading US officials to chide Beijing for not sharing information about the potentially hazardous object's descent.

Chemicals leaking from plastic waste make bacteria grow faster in European lakes, according to research published Tuesday that authors said could provide a natural way to remove plastic pollution from freshwater ecosystems.

This luminescent image features multiple galaxies, perhaps most noticeably LEDA 58109, the lone galaxy in the upper right. LEDA 58109 is flanked by two further galactic objects to its lower left—a galaxy with an active galactic nucleus (AGN) called SDSS J162558.14+435746.4 that partially obscures the galaxy SDSS J162557.25+435743.5, which appears to poke out to the right behind the AGN.

After being installed on the exterior of the International Space Station, NASA's Earth Surface Mineral Dust Source Investigation (EMIT) mission has provided its first view of Earth. The milestone, called "first light," took place at 7:51 p.m. PDT (10:51 p.m. EDT) on July 27 as the space station passed over Western Australia.

Hundreds of miles apart, but still connected by the same stubborn weather system, urban St. Louis and rural Appalachia are showing how devastating flash flooding can be when souped-up storms dump massive amounts of rain with no place to go.

Trapped homeowners swam to safety and others were rescued by boat as record flash flooding killed at least 16 people in Kentucky and swamped entire Appalachian towns, prompting a frenzied search for survivors Friday through some of the poorest communities in America.

Similar to humans, chimpanzees use communication to coordinate their cooperative behavior—such as during hunting. When chimpanzees produce a specific vocalization, known as the "hunting bark," they recruit more group members to the hunt and capture their prey more effectively, researchers at the University of Zurich and Tufts University have now shown.

Neanderthals are the closest relatives to modern humans. Comparisons with them can therefore provide fascinating insights into what makes present-day humans unique, for example regarding the development of the brain. The neocortex, the largest part of the outer layer of the brain, is unique to mammals and crucial for many cognitive capacities. It expanded dramatically during human evolution in...

Falls are a serious public health issue, resulting in tens of thousands of deaths annually and racking up billions of dollars in healthcare costs. While there has been extensive research into the biomechanics of falls, most current approaches study how the legs, joints, and muscles act separately to respond, rather than as a system. The ability to measure how these different levels relate to each...

At least 15 people have died in Kentucky in flash flooding caused by torrential rains that swept away homes and left some residents stranded on rooftoops, the governor of the US state said Friday.

Consumer sentiment was essentially unchanged from June, when it had reached an all-time low for the survey, according to the University of Michigan Surveys of Consumers.

Extreme weather events linked to climate change caused about $65 billion in total losses in the first half of 2022, roughly half of which hit uninsured assets, according to data compiled by Munich Re.

For more than a decade, Congressional Democrats and a growing share of their political base have chased a dream: legislation to combat climate change, large enough to transform our society into one equipped to avert the worst catastrophes of a rapidly warming planet.

Removing several hundred billion tons of carbon from the atmosphere is now considered necessary to avert the worst effects of climate change. Using nature to help achieve that goal, by allowing habitats to regenerate, would seem to offer a win-win solution for the environment and the climate.

A multi-institutional team of researchers and collaborators successfully executed an integrated vessel confinement system (VCS) experiment at Lawrence Livermore National Laboratory (LLNL), as part of an experimental campaign to study how nuclear materials react to high explosives without conducting a traditional nuclear test.

Our aging cities are badly in need of regeneration. Many established residential areas, the "greyfields," are becoming physically, technologically and environmentally obsolete. They are typically located in low-density, car-dependent middle suburbs developed in the mid to late 20th century.

Sustainable fishing is a growing concern worldwide. But how easily can fisheries achieve sustainability? A survey conducted as part of the EU-funded EcoScope project sought to discover what EU fishery stakeholders thought were the main difficulties in sustainably managing European fisheries in the years to come.

,Holes in sea ice provide the perfect hunting ground for polar bears looking to catch their main food source—seals. So when rising temperatures cause sea ice to melt, polar bears' existence is threatened, making them the poster species for many climate change reports and documentaries. While every population of polar bears is threatened by the loss of this sea ice, some have developed...

A foundational element of plant metabolism is the transport of water from the ground to the leaves. In most plants, this task is facilitated by xylem, a tissue whose structure provides hydraulic pathways that aid the water's upward movement. As plants face stressors such as drought, they respond by modifying their transport characteristics. Thus, an accurate understanding of their hydraulic...

Zeta Ophiuchi has had an interesting life. It began as a typical large star about twenty times more massive than the sun. It spent its days happily orbiting a large companion star until its companion exploded as a supernova about a million years ago. The explosion ejected Zeta Ophiuchi, so now it is speeding away through interstellar space. Of course, the supernova also expelled the outer layers...
