An international team of scientists has identified a long-sought protein that causes liver fibrosis (scarring), paving the way for new treatments. The research was published in the journal Nature Genetics. Stages of liver disease. Image credit: National Institute of Diabetes and Digestive and Kidney Diseases. The team, led by Professor …

An international team of researchers from the United States and Italy has identified new genetic variants associated with extreme survival and reduced risks for cardiovascular and Alzheimer’s diseases. Schematic of the analyses conducted to discover longevity associated variants (LAV), LAV with significant joint effect on extreme longevity (jLAV), and LAV …

An international team of scientists led by the Rockefeller University has discovered that a variant of the human gene CRY1 (cryptochrome circadian clock 1) slows the internal biological clock, which dictates rhythmic behavior such as sleep/wake cycles. The study was published in the April 6 issue of the journal Cell. …

Title tags are a meaningful on-page ranking factor and are among the most influential factors in determining click-through rate (CTR) from search engine results pages. Higher CTR not only drives more traffic immediately, it also improves organic rankings when combined with good on-site metrics. Title tag CTR is also difficult …

A duo of researchers at Columbia University has identified two genes (TMEM106B and GRN) that greatly impact normal brain aging, starting at around age 65. This drawing shows several of the most important brain structures. Image credit: National Institute for Aging. “If you look at a group of seniors, some …

A research team led by Scripps Research Institute scientist Dr. Supriya Srinivasan has identified a brain hormone that appears to trigger fat burning in the gut. Model depicting the FLP-7/NPR-22 neuroendocrine axis that underlies the 5-HTergic control of body fat loss. In the nervous system, an integrated 5-HT and octopaminergic …

A team of researchers at the University of Warwick, UK, has identified Connexin26 (Cx26) as a key molecule that reacts to carbon dioxide (CO2) in our bodies and activates breathing. The study is published in the journal Proceedings of the Royal Society B. CO2-dependent dye loading of HeLa cells expressing …

An international team of scientists has identified a second gravitational wave event in the data from the twin detectors of the Laser Interferometer Gravitational-Wave Observatory (LIGO). This image depicts two black holes just moments before they collided and merged with each other, releasing energy in the form of gravitational waves. …

A group of researchers in the United Kingdom has identified a set of gene families whose sizes are positively associated with an expanded neocortex — the region of the brain that is involved in higher cognitive behaviors such as language and decision-making, providing new insights into neocortex evolution. An anatomical …

Astronauts on long-duration flights experience visual impairments due to volume changes in cerebrospinal fluid, the clear fluid that helps cushion the brain and spinal cord while circulating nutrients and removing waste materials, according to a study led by Noam Alperin, professor of radiology and biomedical engineering at the University of …
