Scientists, including those from the University of Colorado Boulder, have finally scaled the solar system's equivalent of the Rocky Mountain range.
In a study published today in Nature Astronomy, researchers from the United States and Japan unveil the possible origins of our cosmic neighborhood's "Great Divide." This well-known schism may have separated the solar system just after the sun first formed.
A 2 degrees Celsius rise in temperatures could result in around 2,100 additional deaths from injuries every year in the United States.
This is the finding of research from Imperial College London, Columbia University and Harvard University, published in the journal Nature Medicine.
The strength of the immune system in response to respiratory infections is constantly changing, depending on the history of previous, unrelated infections, according to new research from the Crick.
There are two types of immunity to infections. Adaptive immunity provides immune "memory", allowing a fast and strong immunological response when the same disease is encountered more than once. In contrast, innate immunity provides a broad and less specific first line of defence against all pathogens, and is vital to controlling infections the body has not experienced previously.
A single bright star in the constellation of Indus, visible from the southern hemisphere, has revealed new insights on an ancient collision that our galaxy the Milky Way underwent with another smaller galaxy called Gaia-Enceladus early in its history.
Research carried out by the University of Kent has shown that diets are changing in complex ways worldwide. International food supply patterns are supporting healthier diets in parts of the world, but causing underweight and obesity elsewhere. They are also having important effects on environmental sustainability, with potentially worrying consequences.
CORVALLIS, Ore. - Marijuana use among college students has been trending upward for years, but in states that have legalized recreational marijuana, use has jumped even higher.
An Oregon State University study published today in Addiction shows that in states where marijuana was legalized by 2018, both occasional and frequent use among college students has continued to rise beyond the first year of legalization, suggesting an ongoing trend rather than a brief period of experimentation.
When it comes to the biggest and brightest explosions seen in the Universe, University of Warwick astronomers have found that it takes two stars to make a gamma-ray burst.
New research solves the mystery of how stars spin fast enough to create conditions to launch a jet of highly energetic material into space, and has found that tidal effects like those between the Moon and the Earth are the answer.
Global warming, a major aspect of climate change, is already causing a wide range of negative impacts on many habitats of our planet. It is thus of the utmost importance to understand how rising temperatures may affect animal health and welfare. A research group from Department of Biology, University of Copenhagen has just shown that tardigrades are very vulnerable to long-term high temperature exposures. Animals, which in their desiccated state are best known for their extraordinary tolerance to extreme environments.
Even though hepatitis E causes over three million infections and about 70,000 deaths each year, the virus has been little studied as yet. This may be about to change, because a research team from Bochum and Hanover has developed a robust and improved cell model of the pathogen. It produces about 100 times more infectious virus particles than previous models. "As a result, we are finally able to study the virus in depth," says Professor Eike Steinmann, Head of the Department for Molecular & Medical Virology at Ruhr-Universität Bochum (RUB).
In the cover article of the Cell Press journal Structure, the authors - among them Dr. Manuel Etzkorn (HHU/FZJ) and Prof. Dr. Michael Famulok (Bonn) - now describe how the interface functions and what substances can interact with it.
One of the things that control cell growth are proteins in the cell membrane. In this regard, EGF receptors ('EGF' stands for Epidermal Growth Factor) form a central interface between the cell and its environment. This is why disruption to this system is a frequent cause of cancers, which arise from incorrectly controlled cell growth.
A research team led by Profs. GAO Caixia and LI Jiayang from the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences have engineered five saturated targeted endogenous mutagenesis editors (STEMEs) and generated de novo mutations to facilitate the directed evolution of plant genes. Their study was published in Nature Biotechnology on Jan. 13.
Though leaded gas and lead-based paint were banned decades ago, the risk of lead exposure is far from gone. A new study led by Elizabeth Sowell, PhD, shows that living in neighborhoods with high risk of lead exposure is associated with differences in brain structure and cognitive performance in some children. Her findings, published by Nature Medicine, also show a deeper trend - children in lower income families may be at increased risk.
Tracking sugar in the blood is crucial for both healthy individuals and diabetic patients. Current methods to measure glucose requires needles and repeated fingerpicks over the day. Fingerpicks can often be painful, deterring patient compliance.
A new technique developed by researchers at the University of Warwick uses the latest findings of Artificial Intelligence to detect hypoglycaemic events from raw ECG signals, via wearable sensors
CHAMPAIGN, Ill. -- Luxury brands and corporate social responsibility initiatives make for unlikely bedfellows - the former with their self-enhancement values, the latter with its ethos of self-transcendence.
A lab goof with an enzyme taken from bacteria has led to the creation of the Leviathan of polymer brushes, emerging biocompatible materials with the potential to repel infectious bacteria.
Polymer brushes are surfaces normally covered with nanoscale bristles made of polymers, spaghetti-like molecular chains that are synthesized chemically. But in a new study, a team led by researchers at the Georgia Institute of Technology stumbled onto a biological technique to improve on the brushes by growing the bristles into giants 100 times the usual length.
