Ponderosa pine forests in the Sierra Nevada that were wiped out by western pine beetles during the 2012-2015 megadrought won't recover to pre-drought densities, reducing an important storehouse for atmospheric carbon.

Eating lots of fats increases the risk of metabolic disorders, but the mechanisms behind the problem have not been well understood. Now, biologists have made a key finding about how to ward off harmful effects caused by a high-fat diet.

Placing levies on the profits made in the renewable energy industry could hinder the UK's ability to meet its 2050 net zero carbon reduction targets, an expert has said.

Whether you're afraid of dogs, needles or enclosed spaces, one of the most effective interventions for this type of anxiety disorder is exposure therapy in which you confront your fear in a safe environment. A new study finds that exposure therapy is also a promising treatment for adolescents with eating disorders. They found that exposure to feared foods -- such as candy bars and pizza -- helped...

Researchers have developed a way to create photonic time crystals and shown that these bizarre, artificial materials amplify the light that shines on them. These findings could lead to more efficient and robust wireless communications and significantly improved lasers.

A new study provides a complete design overhaul for IMCs by creating a broadly applicable strategy that solves key challenges in the design of ear tubes and other 'implantable medical conduits.' The approach enables IMCs with predictable and effective uni- and bi-directional fluid transport at the millimeter scale that resist various contaminations.

It's the spines. New research shows that the spiny pollen from plants in the sunflower family (Asteraceae) both reduces infection of a common bee parasite by 81 -- 94% and markedly increases the production of queen bumble bees. The research provides much-needed food for thought in one of the most vexing problems facing biologists and ecologists: how to reverse the great die-off of the world's...

The early universe was a rambunctious place where galaxies often bumped into each other and even merged together. Using NASA's Hubble Space Telescope and other space and ground-based observatories, astronomers investigating these developments have made an unexpected and rare discovery: a pair of gravitationally bound quasars, both blazing away inside two merging galaxies. They existed when the...

About 12% of the total global energy demand comes from heating and cooling homes and businesses. A new study suggests that using underground water to maintain comfortable temperatures could reduce consumption of natural gas and electricity in this sector by 40% in the United States. The approach, called aquifer thermal energy storage (ATES), could also help prevent blackouts caused by high power...

Scientists have found that human ribosomes decode mRNA slower than bacteria, with implications for drug development.

Solid-state Lithium-Sulfur batteries offer the potential for much higher energy densities and increased safety, compared to conventional lithium-ion batteries. However, the performance of solid-state batteries is currently lacking, with slow charging and discharging being one of the primary causes. Now, a new study shows that sluggish lithium ion transport within a composite cathode is the cause...

Natural disasters can devastate a region, abruptly killing the species that form an ecosystem's structure. But how this transpires can influence recovery. While fires scorch the landscape to the ground, a heatwave leaves an army of wooden staves in its wake. Storm surges and coral bleaching do something similar underwater.

Researchers are studying the genes of superbugs to aid the development of new and effective treatments for drug-resistant bacterial infections. Superbugs are characterized as infection-causing bacteria resistant to treatment with antibiotics.

Feeling like we have a degree of control makes us tolerate pain better. In the case of fibromyalgia, however, this simply doesn't work. A study provides clues as to why.

Chemotherapy treatments produce strong side effects. A new agent that accumulates in the tumour tissue and is activated there by ultrasound waves does not have this problem.

Unlocking the secrets of magnetic materials requires the right illumination. Magnetic x-ray circular dichroism makes it possible to decode magnetic order in nanostructures and to assign it to different layers or chemical elements. Researchers have succeeded in implementing this unique measurement technique in the soft-x-ray range in a laser laboratory. With this development, many technologically...

A framework has been developed to test disgust and its associated disease avoidance behaviors across various animal species, social systems, and habitats. Over 30 species have been predicted to exhibit disease avoidance strategies in the wild. With these predictions, the team accounts for models of specific ecological niches, sensory environments and social systems for a number of species...

A recent study sheds light on the mechanisms of neural plasticity induced by the antidepressant fluoxetine.

Researchers have found people have more efficient conversations, use more positive language and perceive each other more positively when using an artificial intelligence-enabled chat tool.

A warmer Arctic has been linked to extreme winter weather in the midlatitude regions. But, it is not clear how global warming affects this link. In a new study, researchers show, using weather data and climate models, that while the 'Warm Arctic-Cold Continent' pattern will continue as the climate continues to warm, Arctic warming will become a less reliable predictor of extreme winter weather in...

Ice sheets can retreat up to 600 meters a day during periods of climate warming, 20 times faster than the highest rate of retreat previously measured. An international team of researchers used high-resolution imagery of the seafloor to reveal just how quickly a former ice sheet that extended from Norway retreated at the end of the last Ice Age, about 20,000 years ago.

In a twist on the question, 'Which came first, the chicken or the egg?', scientists have long faced a similar question about how human adenovirus replicates: 'Which comes first, assembly of the viral particle, or packaging of the viral genome?' Now, in a new study, scientists have answered that question, showing that viral proteins use a process called phase separation to coordinate production of...

By observing the night sky, medieval monks unwittingly recorded some of history's largest volcanic eruptions. An international team of researchers drew on readings of 12th and 13th century European and Middle Eastern chronicles, along with ice core and tree ring data, to accurately date some of the biggest volcanic eruptions the world has ever seen. Their results uncover new information about one...

Investigators found AI proved superior in assessing and diagnosing cardiac function when compared with echocardiogram assessments made by sonographers.
