A new typing model simulates the typing process instead of just predicting words.

The first health impact study of coal train pollution centers on the San Francisco Bay Area, with scientists finding communities near passing coal trains suffer worse health outcomes.

Contrary to previous assumptions, nerve cells in the human neocortex are wired differently than in mice. The study found that human neurons communicate in one direction, while in mice, signals tend to flow in loops. This increases the efficiency and capacity of the human brain to process information. These discoveries could further the development of artificial neural networks.

The energy density of supercapacitors -- battery-like devices that can charge in seconds or a few minutes -- can be improved by increasing the 'messiness' of their internal structure. Researchers used experimental and computer modelling techniques to study the porous carbon electrodes used in supercapacitors. They found that electrodes with a more disordered chemical structure stored far more energy than electrodes with a highly ordered structure.

Land subsidence is overlooked as a hazard in cities, according to new research. Scientists used satellite data that accurately and consistently maps land movement across China.

Researchers have uncovered a mechanism in the brain that allows cocaine and morphine to take over natural reward processing systems.

Researchers have identified a potential new treatment for persistent neurological symptoms of Lyme disease, commonly seen even after antibiotic use. The study found that fibroblast growth factor receptor inhibitors, previously studied in cancer, significantly reduced inflammation and cell death in infected brain and nerve tissues.

The annual influenza vaccine has become less effective on average over time. One reason may be reduced vaccine efficacy in people with obesity than those with a healthier body mass index (BMI), while the number of people with high BMI grows. Findings showed switching mice to a healthy diet four weeks before influenza vaccination protected 100% from a later flu exposure, despite still having a high BMI.

Twin studies have proven invaluable for teasing out the effects of both genetics and the environment on human biology. Researchers studied pairs of twins to look at how the interplay of genetics and environment affect cognitive processing -- the way that people think. They found that some cognitive abilities appear to be regulated more by environmental factors than by genetics.

Superior decision-making in sports such as soccer could come down to the process of inhibiting a motor response, according to a new study.

A sensitive perception of the environment is crucial for guiding our behavior. However, an overly sensitive response of the brain's neural circuits to stimuli can lead to neurodevelopmental disorders such as epilepsy. Researchers now report how neuronal networks in the mouse brain are fine-tuned.

In posttraumatic stress disorder (PTSD), intrusive thoughts, changes in mood, and other symptoms after exposure to trauma can greatly impact a person's quality of life. About 6 percent of people who experience trauma develop the disorder, but scientists don't yet understand the neurobiology underlying PTSD. Now, a new genetic study of more than 1.2 million people has pinpointed 95 loci, or locations in the genome, that are associated with risk of developing PTSD, including 80 that had not been previously identified.

Most cancer patients do not benefit from early targeted therapies. Scientists now describe a new computational pipeline to systematically predict patient response to cancer drugs at single-cell resolution.

Companies can't simply walk away from old oil and gas wells. They have to be capped in a way that protects the environment and prevents leaks. A new approach to today's solution could be better for the environment and cheaper, too.

Monitoring and treating a case of multiple sclerosis requires reliable and long-term data on how the disease is progressing in the person in question. Fitness trackers and smartphones can supply this data, as a research team has now shown.

Two siblings who have the only known mutations in a key gene anywhere in the world have helped scientists gain new insights that could help progress the search for new treatments in type 1 diabetes.

Autism spectrum disorder has yet to be linked to a single cause, due to the wide range of its symptoms and severity. However, a recent study suggests a promising new approach to finding answers, one that could lead to advances in the study of other neurological conditions.

AI developments in chemical biology could unlock new types of disease treatments.

Thought emerges and is controlled in the brain via the rhythmically and spatially coordinated activity of millions of neurons, scientists argue in a new article. Understanding cognition and its disorders requires studying it at that level.

Scientists created four cannabis-derived CBN analogs (chemical look-a-likes) with enhanced neuroprotective properties and potential for therapeutic application in neurological disorders like Alzheimer's, Parkinson's, and traumatic brain injury. Their findings reveal novel aspects of CBN's neuroprotective activity and demonstrate the clinical potential of CBN and value of studying its analogs.

The harder your brain works at your job, the less likely you may be to have memory and thinking problems later in life, according to a new study. This study does not prove that stimulating work prevents mild cognitive impairment. It only shows an association.

In the long history of recommendations for nutritional intake, current research is trending toward the concept of 'food as medicine' -- a philosophy in which food and nutrition are positioned within interventions to support health and wellness.

It's not a single pesticide or virus stressing honey bees, and affecting their health, but exposure to a complex web of multiple interacting stressors encountered while at work pollinating crops, found new research. Scientists have been unable to explain increasing colony mortality, even after decades of research examining the role of specific pesticides, parasitic mites, viruses or genetics. This led the research team to wonder if previous studies were missing something by focusing on one stressor at a time.

In a new study, researchers show that elevated levels of proteins related to cellular senescence, or aging, in the blood and the placenta are linked to this form of heart failure.
