A new study by researchers at St. Jude Children’s Research Hospital and the University of California Irvine shows that the conformation of proteins can be significantly distorted by the practice of freezing with liquid nitrogen preparatory to analysis by X-ray crystallography.
Nature is full of repeating patterns that are part of the beauty of our world. An international team, including a researcher from the University of Washington, used modern tools to explain repeating patterns of stones that form in cold landscapes.
Lund University has issued the following press release: Our DNA is very similar to that of the chimpanzee, which in evolutionary terms is our closest living relative.
Scientists studying probiotics, beneficial bacteria that show promise for their ability to treat inflammatory bowel disease and other intestinal disorders, continue to face a problem: how to keep probiotics from getting obliterated in the gut before they can be helpful.
Researchers at the Universities of Helsinki and Lyon and the Geological Survey of Finland found that complex teeth, a hallmark of mammals, also evolved several times in reptiles, prompting the evolutionary success of plant-eating lizards. However, contrary to mammals their tooth evolution was not unidirectional.
Researchers have shed new light on evolutionary processes in the last 50,000 years that have allowed some disease-causing genes to persist in human populations.
With future space exploration in mind, a Cornell-led team of astronomers has published the final maps of Titan’s liquid methane rivers and tributaries – as seen by NASA’s late Cassini mission – so that may help provide context for Dragonfly’s upcoming 2030s expedition.
Discovery is similar to fossils from Devonian period
Plants know winter is coming. But exactly how they detect this seasonal change has never been clear.
Recent advances in the development of monoclonal antibodies have shown promise in the treatment of infectious diseases.
A new blood assay, designed to detect four different antibodies associated with SARS-CoV-2 infection, promises to increase diagnostic accuracy and to help researchers understand the spread of COVID-19.
How should we think about historical figures who continue to be relevant to philosophical, scientific and political thinking today?
An automated framework can help scientists in predicting the properties of materials from molecular simulations and are important in making it faster and easier to to understand biological and chemical phenomena, according to a research team.
How natural selection eliminates harmful mitochondrial DNA mutations in mammalian egg cells (oocytes) is a subject of current scientific debate and is under examination by a London university research team.
Researchers at the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) and Colorado School of Mines are applying a new technique to identify defects in silicon solar cells that cause a drop in efficiency.
In the past few years, suitably engineered stacks of two-dimensional materials have emerged as a powerful platform for studying quantum correlations between electronic states. ETH physicists now demonstrate how key properties of such systems can be conveniently tuned by changing an applied electrical field.
Over time, concrete cracks and crumbles. Well, most concrete cracks and crumbles. Structures built in ancient Rome are still standing, exhibiting remarkable durability despite conditions that would devastate modern concrete.
Latest scientific findings suggest the ancestral Native American population does not originate in Japan, as believed by many archeologists
Psychology increasingly characterizes cognition as the process of an individual acting in the environment in which he or she develops, instead of a kind of computational processing of information in the brain.
Child psychiatric disorders, such as oppositional defiant disorder and attention-deficit/hyperactivity disorder (ADHD), can feature outbursts of anger and physical aggression. A better understanding of what drives these symptoms could help inform treatment strategies.
