By the time you reach the end of this sentence, RNA folding will have taken place in your body more than 10 quadrillion times. The folding of RNA is essential to life, yet because it happens so rapidly, researchers have difficulty studying the process.
A study's participants who were asked to think about their own death before taking to the basketball court scored more points than those in a control group.
An ability to delay immediate gratification is associated with less frequent consumption of fast food, research indicates. The study has public health significance since away-from-home eating, and fast food consumption in particular, contribute to obesity in the United States.
Researchers explore the delicate balance between coherence and control with a simple but complete platform for quantum processing.
A new, less invasive way has been developed to perform transcatheter aortic valve replacement (TAVR), a procedure widely used to treat aortic valve stenosis, a lethal heart condition. The new approach, called transcaval access, will make TAVR more available to high risk patients, especially women, whose femoral arteries are too small or diseased to withstand the standard procedure.
Scientists face many constraints when embarking on new projects. Often the biggest constraint is a small budget. This is why one team of scientists recently worked to make one aspect of genetic research cheaper and easier. They have provided guidelines for research projects using microsatellites and a resource of over five million microsatellites for use in a wide variety of plant species.
For as long as scientists have been listening in on the activity of the brain, they have been trying to understand the source of its noisy, apparently random, activity. In the past 20 years, "balanced network theory" has emerged to explain this apparent randomness through a balance of excitation and inhibition in recurrently coupled networks of neurons. A team of scientists has extended the balanced model to provide deep and testable predictions linking brain circuits to brain activity.
For the first time, research shows the final stages of how mitochondria, the sausage-shaped, power-generating organelles found in nearly all living cells, regularly divide and propagate.
The moon, Earth's closest neighbor, is among the strangest planetary bodies in the solar system. Its orbit lies unusually far away from Earth, with a surprisingly large orbital tilt. Planetary scientists have struggled to piece together a scenario that accounts for these and other related characteristics of the Earth-moon system. A new research paper, based on numerical models of the moon's explosive formation and the evolution of the Earth-moon system, comes closer to tying up all the loose ends than any other previous explanation.
A diet rich in antioxidants and carotenoids is linked to better outcomes for patients with amyotrophic lateral sclerosis, say investigators.
Most college and university students who use closed captions and transcripts on video and multimedia find them helpful as a learning tool, despite them not regularly being made available, according to new research.
Young adults with symptoms of alcohol dependence may see health effects late in life, even decades after conquering their problem drinking, according to a study. Researchers found that, of 664 U.S. male veterans, those who had symptoms of alcohol dependence for at least five years in young adulthood generally had poorer physical and mental health by the time they were in their 60s.
Most Americans under age 35 think that using electronic cigarettes does not cause as much damage lung health as compared with traditional cigarettes, according to the results of a new national consumer survey.
Shotgun marriages have faded in popularity overall, but are on the rise among some groups, shows new research. And not all shotgun marriages are as rocky as one might think.
A new theory regarding how the brain first learns basic math could alter approaches to identifying and teaching students with math learning disabilities. Now researchers offer a better understanding of how, when and why people grasp every day math skills.
A decades-old tax system may offer an economical solution to the problem of catastrophic climate change, according to a new study. A consumer tax levy on fossil fuels could provide a means of lowering their use or encouraging the adoption of cleaner alternatives, the research suggests.
Researchers have identified a mechanism that causes low clouds – and their influence on Earth’s energy balance – to respond differently to global warming depending on their spatial pattern and location.
Normal, healthy heart muscle is well-supplied with oxygen-rich blood. But now cardiologists have been able to regenerate heart muscle by placing mice in an extremely low-oxygen environment.
A new method for customizing ingredients that help oral medications dissolve in the body and be absorbed into the bloodstream has now been discovered by researchers. The materials discovered in this study could allow life-saving drugs to work faster and more efficiently.
Our brain has a tough task every time we experience something new – it must be flexible to take in new information instantly, but also stable enough to store it for a long time. And new memories may not be allowed to alter or overwrite old ones. Now researchers have investigated how different brain regions interact when long-term memories are formed.
