- Toxic chemicals from microplastics can be absorbed through skin April 19, 2024Toxic chemicals used to flame-proof plastic materials can be absorbed into the body through skin, via contact with microplastics, new research shows.
- When thoughts flow in one direction April 18, 2024Contrary 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 […]
- A common pathway in the brain that enables addictive drugs to hijack natural reward processing April 18, 2024Researchers have uncovered a mechanism in the brain that allows cocaine and morphine to take over natural reward processing systems.
- Metacognitive abilities like reading the emotions and attitudes of others may be more influenced by environment than genetics April 18, 2024Twin 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 […]
- Quick decisions in soccer enhanced by brain's ability to suppress actions April 18, 2024Superior decision-making in sports such as soccer could come down to the process of inhibiting a motor response, according to a new study.
- Perfect balance: How the brain fine-tunes its sensitivity April 18, 2024A 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.
- Scientists uncover 95 regions of the genome linked to PTSD April 18, 2024In 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 […]
- AI tool predicts responses to cancer therapy using information from each cell of the tumor April 18, 2024Most 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.
- How data provided by fitness trackers and smartphones can help people with MS April 18, 2024Monitoring 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.
