The development of AI models is an overlooked climate culprit. Computer scientists have created a recipe book for designing AI models that use much less energy without compromising performance. They argue that a model's energy consumption and carbon footprint should be a fixed criterion when designing and training AI models.

A routine blood test that measures a patient's inflammation levels could improve the early diagnosis and management of a wide range of debilitating autoimmune diseases. The Systemic Inflammation Index (SII) uses information from routine laboratory data to measure inflammation in the body and examining this index in a new way could provide vital answers.

Researchers have used a genetic learning algorithm to identify optimal pitch profiles for the blades of vertical-axis wind turbines, which despite their high energy potential, have until now been vulnerable to strong gusts of wind.

Drawing inspiration from the way plants breathe, a group of researchers has created a paper-based magnesium-air battery that can be used in GPS sensors or pulse oximeter sensors. Taking advantage of paper's recyclability and lightweight nature, the engineered battery holds promise for a more environmentally friendly source of energy.

Researchers have made a groundbreaking advancement in battery technology, developing a novel cathode material for rechargeable magnesium batteries that enables efficient charging and discharging even at low temperatures.

California, a state known for its aggressive greenhouse gas reduction policies, is ironically the nation's greatest emitter of one: sulfuryl fluoride. As much as 17% of global emissions of this gas, a common pesticide for treating termites and other wood-infesting insects, stem from the United States. The majority of those emissions trace back to just a few counties in California, finds a new study.

Researchers investigate the influence of social relationships on our bodily responses to the presence of other persons in the interpersonal space.

A new study has found that birds that are more social are more likely to use novel sources of food.

Researchers show that using magnetic fields can boost electrocatalysis for sustainable fuel production by enhancing the movement of the reactants, which improves the efficiency of energy-related reactions.

To better understand COVID-19's spread during the pandemic, public health officials expanded wastewater surveillance. These efforts track SARS-CoV-2 levels and health risks among most people, but they miss people who live without shelter, a population particularly vulnerable to severe infection. To fill this information gap, researchers tested flood-control waterways near unsheltered encampments, finding similar transmission patterns as in the broader community and identifying previously unseen viral mutations.

Until now, groundwater -- a critical water resource around the globe, especially in dry regions -- has been largely unstudied in its importance and role in sustaining ecosystems. New groundbreaking research examines the relationship between groundwater and ecosystems across California.

A new study finds that universities scoring strongly on measures of sustainability are associated with innovation and economic growth in their surrounding communities. However, the study did not find similar connections between university sustainability performance and environmental sustainability in their home communities.

Researchers have developed a programmable meta-fluid with tunable springiness, optical properties, viscosity and even the ability to transition between a Newtonian and non-Newtonian fluid. The first-of-its-kind meta-fluid uses a suspension of small, elastomer spheres -- between 50 to 500 microns -- that buckle under pressure, radically changing the characteristics of the fluid. The meta-fluid could be used in everything from hydraulic actuators to program robots, to intelligent shock absorbers that... Читать дальше...

A genomic study of human and selected nonhuman primate centromeres has revealed their unimaginable diversity and speed of evolutionary change. Although centromeres are vital to proper cell replication by assuring faithful transmision of genetic materials when cells divide, the complexity of their genomic organization had been almost impossible to study. The lack of centromere sequences hindered exploration of how these regions help maintain genetic integrity. Now, advanced technologies have shown... Читать дальше...

Scientists have discovered that bacterial populations remain stable on factory floor despite cleaning efforts in ready-to-eat food production facilities.

As any surfer will tell you, waves pack a powerful punch. Now, we are one step closer to capturing the energy behind the ocean's constant ebb and flow with an improved 'blue energy' harvesting device. Researchers report that simply repositioning the electrode -- from the center of a see-sawing liquid-filled tube to the end where the water crashes with the most force -- dramatically increased the amount of wave energy that could be harvested.

One of the great mysteries of modern science is dark matter. We know dark matter exists thanks to its effects on other objects in the cosmos, but we have never been able to directly see it. And it s no minor thing currently, scientists think it makes up about 85% of all the mass in the universe.

Study reveals that newly hatched chicks can instantly recognize objects with their vision, even if they've only ever experienced them by touch.

Windows welcome light into interior spaces, but they also bring in unwanted heat. A new window coating blocks heat-generating ultraviolet and infrared light and lets through visible light, regardless of the sun's angle. The coating can be incorporated onto existing windows or automobiles and can reduce air-conditioning cooling costs by more than one-third in hot climates.

Adolescents with high positive affect may have improved physical and mental health as adults, according to a new study.

Researchers have found that even low to moderate alcohol use by pregnant patients may contribute to subtle changes in their babies' prenatal development, including lower birth length and a shorter duration of gestation.
