Scientists have shown that people are able to tell apart morning from evening depictions in paintings using simple and subtle color clues in the image.

A combination of cognitive and behavioral strategies, ideally delivered in person by a therapist, maximizes the benefits of cognitive behavioral therapy for insomnia (CBT-I), according to new research. CBT-I is a form of talk therapy, which can be delivered in person or through self-help guides. By analyzing 241 studies, involving over 30,000 adults, researchers identified the most beneficial components of CBT-I.

New algorithms close the gap in deepfake detectors' accuracy across races and genders.

A 10-month mission demonstrated three elements of the plan to beam solar power from space to Earth.

Scientists have made an insight into superlubricity, where surfaces experience extremely low levels of friction. This could benefit future technologies by reducing energy lost to friction by moving parts.

Scientists have successfully demonstrated new technologies that can obtain preserved tissue and high-resolution 3D images within minutes of encountering some of the most fragile animals in the deep ocean.

Researchers have linked the travels of a 14,000-year-old woolly mammoth with the oldest known human settlements in Alaska, providing clues about the relationship between the iconic species and some of the earliest people to travel across the Bering Land Bridge. Isotopic data, along with DNA from other mammoths at the site and archaeological evidence, indicates that early Alaskans likely structured their settlements to overlap with areas where mammoths congregated. Those findings, highlighted in the new issue of the journal Science Advances, provide evidence that mammoths and early hunter-gatherers shared habitat in the region. The long-term predictable presence of woolly mammoths would have attracted humans to the area.

Having more women in agriculture is associated with greater community well-being, according to researchers. Their work suggests that women farmers approach their operations in ways that positively impact their communities.

Just like a book can't be judged by its cover, a material can't always be judged by its surface. But, for an elusive conjectured class of materials, physicists have now shown that the surface previously thought to be 'featureless' holds an unmistakable signature that could lead to the first definitive observation.

Researchers report the development of a methodology to detect small amounts of potential tumor therapeutic targets, specificacally enzymes called kinases, that are present in biopsy samples. Therapies that directly inhibit cancer-promoting activities of some of these kinases have proven to be effective for patients in which individual driving kinases can be diagnosed.

Sustainable water management is an increasing concern in arid regions around the world, and scientists and regulators are turning to remote sensing tools like OpenET to help track and manage water resources. OpenET uses publicly available data produced by NASA and USGS Landsat and other satellite systems to calculate evapotranspiration (ET), or the amount of water lost to the atmosphere through soil evaporation and plant transpiration, at the level of individual fields. This tool has the potential to revolutionize water management, allowing for field-scale operational monitoring of water use, and a new study provides a thorough analysis of the accuracy of OpenET data for various crops and natural land cover types.

Scientists recently revealed the latest National Seismic Hazard Model, showing that nearly 75% of the United States could experience a damaging earthquake, emphasizing seismic hazards span a significant part of the country.

A mouse study designed to shed light on memory loss in people who experience repeated head impacts, such as athletes, suggests the condition could potentially be reversed. The research in mice finds that amnesia and poor memory following head injury is due to inadequate reactivation of neurons involved in forming memories.

Climate change is causing Western U.S. forests to be less effective carbon sinks, even as it boosts the productivity of forests in the Eastern U.S., according to new research.

Fossils of kelp along the Pacific Coast are rare. Until now, the oldest fossil dated from 14 million years ago, leading to the view that today's denizens of the kelp forest -- marine mammals, urchins, sea birds -- coevolved with kelp. A recent amateur discovery pushes back the origin of kelp to 32 million years ago, long before these creatures appeared. A new analysis suggests the first kelp grazers were extinct, hippo-like animals called desmostylians.

This month, a group of stroke survivors in British Columbia will test a new technology designed to aid their recovery, and ultimately restore use of their limbs and hands. Participants will wear a new groundbreaking 'smart glove' capable of tracking their hand and finger movements during rehabilitation exercises.

Supersulfides, many of which are produced by cysteinyl-tRNA synthetase (CARS), are essential compounds across many different lifeforms. However, the precise physiological roles of CARS-produced supersulfide are unclear. Now, using a strategically engineered yeast mutant with a deficient CARS gene, researchers from Japan have shown that supersulfides control cell longevity by mediating mitochondrial energy metabolism and regulating protein quality.

'Soft robots,' medical devices and implants, and next-generation drug delivery methods could soon be guided with magnetism -- thanks to a metal-free magnetic gel developed by researchers. Carbon-based, magnetic molecules are chemically bonded to the molecular network of a gel, creating a flexible, long-lived magnet for soft robotics.

New research shows the early lunar crust which makes up the surface of the Moon was considerably enriched in water more than 4 billion years ago, counter to previously held understanding.

A study exploring the mechanisms behind why cognitive performance improves in response to exercise, has found that dopamine plays a key role.
