We all know how babies are made: sperm meets egg, molecular magic happens, and an entire human comes to life from a single cell. But is that the only way? For a decade, scientists have been in a heated race to redefine r...

The next time you're at a hospital, you might want to think twice before touching the privacy curtains that hang around patient beds, a small new study finds.

The remarkable discoveries and theories of physicists since the 1930s have shown that all matter in the universe is made from a small number of basic building blocks called fundamental particles. However, this isn't the ...

A technique using umbilical cord blood stem cells could be a promising new approach for repair of cleft palate in infants, researcher report.

In an innovative study that promises to reduce production costs for the most potent form of vitamin K, Menaquinone-7, researchers have developed a novel method to enhance the fermentation process that creates the supplem...

Researchers describe a new means of searching vast repositories of compounds produced by microbes. By analyzing the mass spectra of the compounds, they were able to identify known compounds within the repository and elim...

Together, genetics and years of education can influence whether or not someone becomes obese, a new study finds.

Heart experts have long believed that weekday mornings -- and especially Mondays -- were the danger zones for unexpected deaths from sudden cardiac arrests. But a new study shows those peak times have disappeared and now...

A new cost-effectiveness study estimates that nearly one million cardiovascular and diabetes events could be prevented and $42 billion could be saved in healthcare costs by including food incentives and disincentives for...

Human milk oligosaccharides (HMOs) are complex carbohydrates that are highly abundant and unique to human milk. Accumulating evidence indicates that exposure to HMOs in the postnatal period has both immediate and long-te...

Studies on red and processed meat consumption with breast cancer risk have generated inconsistent results. A new analysis has now examined all published studies on the topic. Comparing the highest to the lowest category ...

Preliminary findings from a pilot study suggest that cognitive behavioral therapy for insomnia (CBT-I) may slow or even reverse the atrophy of cortical gray matter in patients who have co-morbid fibromyalgia.

The study showed that the increased presence of a protein responsible for sensing infection -- called NLRP1 -- meant there were fewer good bacteria and anti-inflammatory molecules in the gut, leading to higher levels of ...

Previous research showed it was possible to reduce the burden of damaged cells, termed senescent cells, and extend lifespan and improve health, even when treatment was initiated late in life. They now have shown that tre...

By venturing beyond the lab mouse to study the eyes of diurnal small mammals, scientists have uncovered a difference in the composition of rod and cone cell membranes that may explain how a genetic form of macular dystro...

Cancer researchers have just discovered a way to make immunotherapy viable to thousands by using the body's own natural killer (NK) cells in a new way.

(Graz University of Technology) Researchers from Graz University of Technology have described for the first time the dynamics which takes place within a trillionth of a second after photoexcitation of a single atom insid...

At its core, physics is the study of matter and energy--the fundamental fabric of the universe. It's a field seemingly full of paradoxes: accelerator rings 15 miles around help us examine the smallest things imaginable. ...

When Canadian scientist Donna Strickland got the early morning call informing her she just won the Nobel Physics Prize, she could barely hide her amazement.

The U.S. Department of Energy's Critical Materials Institute has taken a major step toward printed, aligned anisotropic magnets via additive manufacturing processes.

Arthur Ashkin, Gérard Mourou and Donna Strickland shared the Nobel Prize for finding ways to control and enhance laser light, leading to numerous common applications. --

Researchers report those with dark triad personality traits tend to dream more about aggression and sex.
