Researchers contributed to a deeper understanding of free electron laser physics by evaluating the interaction between an ultraviolet laser and a relativistic electron beam in a pure dipole magnet. The team used a 266-nm laser at the soft x-ray FEL test facility to modulate an 800-MeV electron beam....The results showed that a short dipole magnet can serve as an effective tool for introducing...

The extent of vaccine nationalism, wherein countries stockpile vaccines to prioritize access for their citizenry over equitable vaccine sharing, may strongly impact global trajectories of COVID-19 case numbers and increase the potential emergence of novel variants, according to a new study.

For decades, there has been an accepted definition of dieting in academia, and in society as a whole. Researchers recently reevaluated the decades of dieting research to redefine the way researchers and the public define -- and therefore understand - dieting and the culture of weight loss.

Scientists have developed a bioprocess using engineered yeast that completely and efficiently converted plant matter consisting of acetate and xylose into high-value bioproducts.

Ecologists show that 1,330 nurseries, garden centers and online retailers are still offering hundreds of invasive plant species as ornamental garden plants. This includes 20 species that are illegal to grow or sell nationwide.

While other simulations have modeled black hole growth, new model is the first single computer simulation powerful enough to comprehensively account for the numerous forces and factors that play into the evolution of supermassive black holes. Simulation shows that galaxies' spiral arms 'put the brakes on gas,' enabling it to fall into the black hole and as gas heats up while falling into a black...

Researchers have found that the delta variant of the virus that causes COVID-19 is largely unable to evade antibodies elicited by vaccination. The findings help explain why vaccinated people have been at low risk of getting seriously ill with COVID-19 despite a surge in cases caused by the delta variant.

Violent activity on our Sun leads to some of the most extreme space weather events on Earth, impacting systems such as satellites, communications systems, power distribution and aviation. The roughly 11 year cycle of solar activity has three 'seasons', each of which affects the space weather felt at Earth differently: (i) solar maximum, the sun is active and disordered, when space weather is...

A previously healthy infant who suffered aborted sudden cardiac death was found to have a de novo genetic mutation in the SOS1 gene. Such mutations are typical of Noonan syndrome and suggests the syndrome may be a cause of unrecognized sudden death in infancy.

Scientists have designed a 3D-bioprinted model of a blood vessel that mimics its state of health and disease, thus paving the way for possible cardiovascular drug advancements with better precision.

Recent research has found that changes in the gut microbiota -- the trillions of bacteria and other microbes that live in the intestines -- can alter the brain and behavior. A new study could elucidate how and why that phenomenon occurs.

New research suggests that officials should prioritize contact tracing and quarantine.

Scientists have developed a novel strategy using brain-wide genome-editing technology that can reduce Alzheimer's disease(AD) pathologies in genetically modified AD mouse models. This advanced technology offers immense potential to be translated as a novel long-acting therapeutic treatment for AD patients.

A survey of more than 17,000 pregnant and lactating women who received the COVID-19 vaccine showed that they did not experience symptoms any more severe than their non-pregnant counterparts.

Time-restricted eating (TRE), a dietary regimen that restricts eating to specific hours, has garnered increased attention in weight-loss circles. A new study further shows that TRE confers multiple health benefits besides weight loss. The study also shows that these benefits may depend on sex and age.

Researchers describe a simple model that captures the key mechanics of hand-washing, estimating the time scales on which particles, like viruses and bacteria, were removed. Particles are trapped on the rough surfaces of the hand in potential wells, as though they are at the bottom of a valley and the energy from the water flow must be high enough to get them up and out of the valley.

To fully harness the potential of sunlight, scientists have been trying to maximize the amount of energy that can be extracted from the sun. Researchers now describe how pairing metal halide perovskites with conventional silicon leads to a more powerful solar cell that overcomes the 26% practical efficiency limit of using silicon cells alone. Perovskites fulfill all the optoelectronic requirements...

If you're a male chimp looking for love -- or offspring -- it pays to make friends with other males. A study examined why male chimpanzees form close relationships with each other, and found that male chimpanzees that build strong bonds with the alpha male of the group, or with a large network of other males, are more successful at siring offspring.

An international research team may have found that a protein implicated in tumor growth may be able to help regulate awry cellular translation and protect against neuronal decay.

Researchers have, with the help of cryogenic electron microscopy, succeeded in producing a high-resolution image of photosystem II - the central complex of photosynthesis - of the model plant Arabidopsis. The enormous complex is responsible for the vital oxygen production in photosynthesis that once made life possible on our planet.

New research has uncovered considerable class differences in the gender revolution of who holds the purse strings among British couples. Low-earning and high-earning women are taking more control of the finances in their relationships, but in different ways, says the research.

New research has found that the habitats of West African (western) chimpanzees are threatened due to inadequate legislative protection from human development.

Researchers address some of the questions surrounding these massive and enigmatic features of the universe by using new, high-powered simulations.

Bodily inflammation dampens levels of a 'feel-good molecule' and antidepressants' ability to boost them, according to new research in mice.
