New research by an environmental scientist reveals that deforestation in the U.S. does not always cause planetary warming, as is commonly assumed; instead, in some places, it actually cools the planet.

Astrocytes -- star-shaped cells in the brain that are actively involved in brain function -- may play an important role in stuttering, a study led by an expert on stuttering has found. The study also suggests that treatment with the medication risperidone leads to increased activity of the striatum in persons who stutter.

Fast and energy-efficient future data processing technologies are on the horizon after an international team of scientists successfully manipulated magnets at the atomic level.

In your quest for true love and that elusive happily ever after, are you waiting for the 'right' person to come along, or do you find yourself going for the cutest guy or girl in the room, hoping things will work out? Do you leave your options open, hoping to 'trade-up' at the next opportunity, or do you invest in your relationship with an eye on the cost-benefits analysis?

The 10-member team made discoveries about a specific area of the brain tied to recollection and the desire to seek and consume food. It could lead to a way to inhibit the desire to overeat.

A new study is directly contradicting the widely accepted cultural transmission hypothesis suggesting that whales learn their songs from other whales. 'Our findings indicate that neither cultural transmission nor social learning contributes significantly to how humpback whales change their songs over time.', says one of the researchers.

The rise of significant variants of SARS-CoV-2 has attracted the attention of health and science experts worldwide. In a new editorial, experts outline how these variants have arisen, concerns about whether vaccines currently authorized for use will continue to protect against new variants, and the need for a global approach to fighting SARS-CoV-2 as it spreads and acquires additional mutations.

A new analysis of thousands of native and nonnative Michigan bees shows that the most diverse bee communities have the lowest levels of three common viral pathogens.

In Huntington's disease, a faulty protein aggregates in brain cells and eventually kills them. Such protein aggregates could, in principle, be prevented with a heat shock protein. However, it is not well known how these proteins interact with the Huntington's disease protein. New research has partially resolved the structure of heat shock proteins that bind to such aggregating proteins.

A new study has identified early risk factors that predicted heightened anxiety in young adults during the coronavirus (COVID-19) pandemic. The findings from the study could help predict who is at greatest risk of developing anxiety during stressful life events in early adulthood and inform prevention and intervention efforts.

An interdisciplinary team of scientists has for the first time used dried flowers of St. John's Wort (genus Hypericum) as an active catalyst in various photochemical reactions.

Birdwatchers get excited when 'rare' migratory birds makes landfall having been blown beyond their normal range. But these are rare for a reason; most birds that have made the journey before are able to correct for large displacements and find their final destination. Now new research shows how birds displaced in this way are able to navigate back to their migratory route and gives us an insight...

An international team of scientists has determined how harmless E. coli gut bacteria in chickens can easily pick up the genes required to evolve to cause a life-threatening infection. Their study warns that such infections not only affect the poultry industry but could also potentially cross over to infect humans.

An active lifestyle is linked with a lower chance of dying immediately from a heart attack, according to a new study. Heart disease is the leading cause of death globally and prevention is a major public health priority.

A study has now been presented that boosts the evidence for using AI solutions in skin cancer diagnostics. With an algorithm they devised themselves, scientists show the capacity of technology to perform at the same level as dermatologists in assessing the severity of skin melanoma.

Scientists have discovered the genes involved in autoimmune Addison's disease.

A new brain-and-behavior study clarifies how the 'anomalous-is-bad' stereotype manifests, and implicates a brain region called the amygdala as one of the likely mediators of this stereotype.

New research shows that hurricane maximum wind speeds in the subtropical Atlantic around Bermuda have more than doubled on average over the last 60 years due to rising ocean temperatures in the region.

Scientists use many different tests to investigate what happens in the brain in people experiencing stress. It is unclear to what extent the various methods with which subjects are placed under stress are comparable to each other. In a meta-analysis, researchers compared 31 previous studies that had investigated stress using functional magnetic resonance imaging. The team worked out which regions...

Knowledge on how cells communicate is an important key to understanding many biological systems and diseases. A research team has now used a unique combination of methods to map the mechanism behind cellular communication. Their findings can potentially improve understanding of the underlying mechanism behind type 2 diabetes.

In Sweden, upper-secondary schools moved online while lower-secondary schools remained open during the spring of 2020. A comparison of parents with children in the final year of lower-secondary and first year of upper-secondary school shows that keeping the former open had limited consequences for the overall transmission of the virus. However, the infection rate doubled among lower-secondary...

In chronic infections, the immune system can become exhausted. Researchers have looked into how this works.

Researchers show that the light emitted by a single molecule can be detected with a low-cost optical setup. Their prototype could facilitate medical diagnostics.

When we listen to speech sounds, our brain needs to combine information from both hemispheres. How does the brain integrate acoustic information from remote areas? In a neuroimaging study, a team of researchers applied electrical stimulation to participants' brains during a listening task. The stimulation affected the connection between the two hemispheres, which in turn changed participants'...
