Researchers have successfully developed a 'speech neuroprosthesis' that has enabled a man with severe paralysis to communicate in sentences, translating signals from his brain to the vocal tract directly into words that appear as text on a screen.

Domestic dogs show many adaptations to living closely with humans, but they do not seem to reciprocate food-giving according to a new study.

Keeping your brain active in old age has always been a smart idea, but a new study suggests that reading, writing letters and playing card games or puzzles in later life may delay the onset of Alzheimer's dementia by up to five years.

An environmental sciences professors explain why naming new species may be a never-ending journey.

Having no children who completed college is negatively associated with parents' self-rated health and positively associated with depressive symptoms. Additionally, among parents with the highest propensity for having no children who complete college, the consequences on depressive symptoms are greatest.

Scientists and engineers have devised a new method for making urea that is more environmentally friendly than today's process and produces enough to be competitive with energy-intensive industrial methods.

Roadless national forests in the American West burn more often and at a slightly higher severity than national forests with roads, but the end result for the roadless forests is greater fire resilience, researchers say.

Researchers have created a novel analysis tool that seeks to protect the millions of people living on urban river deltas, while preserving the environmental and commercial viability of these landscapes.

Researchers have discovered that the cell adhesion protein IgSF11 determines the layer-specific synaptic connectivity of a distinct class of cortical interneurons.

Firefighters battling wildfires in the western United States use a variety of suppression tactics to get the flames under control. Prescribed burns, or controlled fires intentionally set to clear shrubs and forest litter before a wildfire ever ignites, can make fire suppression operations almost three times as effective in limiting wildfire severity, according to a new study.

New research illustrates the disparity between the narrow origins and far-reaching impacts of greenhouse emissions responsible for disrupting the global climate system.

A preclinical study offers hope for treatment of uveal melanoma, a rare and deadly cancer of the eye. A small molecule inhibitor has been identified that dampens the potent drivers of this tumor. In mouse models, the inhibitor strongly limited primary disease in the eye and metastatic tumor dissemination to the liver, and animals survived longer, without overt side effects.

With few additional targeted tests and non-invasive surveys, public health agencies can better estimate disease occurrence and trends, changes in transmission, rates of hospitalization and death and effectiveness of vaccines and other control measures.

A previously unknown kind of human brain cell appears to help people center themselves in their personal maps of the world, according to a new study from neuroscientists. This discovery shed light on the cellular mechanisms underlying navigation and memory in humans, as well as what parts of the brain might get disrupted during the kinds of memory impairments common in neurodegenerative diseases...

The quantum movements of a small glass sphere could be controlled for the first time in Vienna by combining microscopy with control engineering, setting the course for future quantum technologies.

A team of scientists has uncovered how heavy, motorized objects climb steep slopes -- a newly discovered mechanism that also mimics how rock climbers navigate inclines.

People with diabetes and depression who take antidepressants may have a lower risk of death and of serious diabetes complications, according to a new study.

Researchers have shown in a brain organoid study that exposure to a common pesticide synergizes with a frequent autism-linked gene mutation.

As temperatures rise, the risk of devastating forest fires is increasing. Researchers are using artificial intelligence to estimate the long-term impact that an increased number of forest fires will have on forest ecosystems. Their simulations show how Yellowstone National Park in the USA could change by the end of the century.

Scientists find that short chain fatty acids can be used to reduce susceptibility to SARS-CoV-2 infection and mortality from COVID-19.

Researchers are working on an easily understood, science-backed way to visually represent hurricane danger to the general public. They contend that the cone of uncertainty creates a false sense of security for people who live outside the boundary of the cone and that there are better ways to signal likely impacts.

Heart attack, or myocardial infarction, is one of the leading causes of death worldwide. Although modern surgical techniques, diagnostics and medications have greatly improved early survival from these events, many patients struggle with the long-term effects of permanently damaged tissue, and the 5-year mortality rate remains high. Now, researchers have developed a minimally invasive exosome...

More and more companies are using chatbots in customer services. Due to advances in artificial intelligence and natural language processing, chatbots are often indistinguishable from humans when it comes to communication. But should companies tell customers they are communicating with machines and not with humans? Researchers investigated. Their research found that consumers tend to react...

Electroconvulsive therapy, which may be effective at lowering long-term risks of suicide and death among patients with certain mood disorders, may result in longer hospital stays and increased health care costs, according to researchers. They said delivering the therapy in outpatient settings may make the treatment more cost-effective.
