Organisms that aren't closely related may evolve similar traits as they adapt to similar challenges. It's called convergent evolution, and familiar examples include the wings of birds, bats, and insects, and echolocation in bats and dolphins. Now, molecular biologists have found evidence of convergent evolution in an important mechanism of gene regulation in humans and mice.
The most urgent course of action to safeguard coral reefs is to reduce global greenhouse gas emissions, but concurrently there is also a need to consider novel management techniques and previously over-looked reef areas for protective actions under predicted climate change impacts. The conclusions were reached following a comprehensive review of the literature on the mechanisms of potential coral resistance and recovery across scales from global reef areas to the microbial level within individual corals.
New researcher shows how Zika virus infection in five pregnant rhesus monkeys caused placental tissues to become thickened and inflamed, resulting in less oxygen being transported across the placenta and to the baby.
It is easier to spread the influenza virus (flu) than previously thought, according to a new study released today. People commonly believe that they can catch the flu by exposure to droplets from an infected person's coughs or sneezes or by touching contaminated surfaces. But, new information about flu transmission reveals that we may pass the flu to others just by breathing.
Columbia University researchers have identified two new breast cancer genes that also cause Lynch syndrome.
Major beer companies have rolled out marketing campaigns and products -- such as 'fan cans,' store displays, and billboard ads -- that pair beer with university colors, mascots, and logos. Research published in the January 2018 issue of Psychological Science shows that such campaigns may enhance the motivational significance of marketed beer brands, especially for students who identify strongly with their university. The researchers conclude that this effect could potentially increase underage students' alcohol consumption.
Beneficial bacteria on the skin of lab mice work with the animals' immune systems to defend against disease-causing microbes and accelerate wound healing, according to new research from scientists at the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health. Researchers say untangling similar mechanisms in humans may improve approaches to managing skin wounds and treating other damaged tissues. The study was published online today in Cell.
Researchers at the University of New Hampshire used high-tech tools to more precisely view where these cleared sites were and how much lasting impact they had on the rainforest in the Amazon Basin in South America.
Dust is everywhere -- not just in your attic or under your bed, but also in outer space. To astronomers, dust can be a tool to study the history of our universe, galaxy, and Solar System. For example, observations indicate that type II supernovae -- explosions of stars more than ten times as massive as the Sun -- produce copious amounts of dust, but how and when they do so is not well understood.
The paper ball-like graphene particles stack into a porous scaffold to suppress filament growth of lithium metal that degrades the battery.
