Scientists used high-performance TEM to image the process of gold atoms assembling into nanocrystals. It was discovered that the atoms undergo a spontaneous transition between disordered and crystalline states.

When their manhood is threatened, some men respond more aggressively than others. New research suggests who may be most triggered by such threats - younger men whose sense of masculinity depends heavily on other people's opinions.

A new study uncovers intriguing genetic similarities between PTSD and other mental health disorders such as anxiety, bipolar disorder, and schizophrenia. The findings also suggest that existing drugs commonly used for other disorders might be modified to help treat individual symptoms of multiple disorders.

Chemists have identified new details of the reaction mechanism that takes place in batteries with lithium metal anodes. The findings are a major step towards developing smaller, lighter, and less expensive batteries for electric vehicles.

Although loggerhead sea turtles return to the same beach where they hatched to lay their eggs, a new study finds individual females lay numerous clutches of eggs in locations miles apart from each other which increases the odds that some of their offspring will survive.

Researchers detail the mechanism that allows propofol, a common anesthetic, to halt the movement of kinesin proteins that deliver cargoes to the far reaches of cells.

When thick, the surface layer of the ocean acts as a buffer to extreme marine heating -- but a new study shows this 'mixed layer' is becoming shallower each year. The thinner it becomes, the easier it is to warm. The new work could explain recent extreme marine heatwaves, and point at a future of more frequent and destructive ocean warming events as global temperatures continue to climb.

A genetic engineering method makes it possible to observe how woody cell walls are built in plants. The new research in wood formation opens up the possibility of developing sturdier construction materials and perhaps more climate efficient trees.

A study has found that adolescents who frequently use cannabis may experience a decline in Intelligence Quotient (IQ) over time. The findings of the research provide further insight into the harmful neurological and cognitive effects of frequent cannabis use on young people.

A new type of rocket thruster that could take humankind to Mars and beyond has been proposed by a physicist. The device would apply magnetic fields to cause particles of plasma to shoot out the back of a rocket and propel the craft forward.

Seawater is abundant and cheap, making it a tempting resource to meet the world's growing need for clean drinking water and carbon-free energy. Now researchers have reported a new catalyst that can be made quickly and inexpensively, bringing the technology closer to commercial reality.

The origin of flowering plants famously puzzled Charles Darwin, who described their sudden appearance in the fossil record from relatively recent geological times as an 'abominable mystery'.

Malaria is an ancient scourge, but it's still leaving its mark on the human genome. And now, researchers have uncovered recent traces of adaptation to malaria in the islanders of Cabo Verde -- thanks to a genetic mutation, inherited from their African ancestors, that prevents a type of malaria parasite from invading red blood cells. The findings represent one of the speediest, most dramatic...

Scientists discovered that AIM2 is important for the proper function of regulatory T cells, or Treg cells, and plays a key role in mitigating autoimmune disease. Treg cells are a seminal population of adaptive immune cells that prevents an overzealous immune response, such as those that occurs in autoimmune diseases.

When a water droplet interacts with a surface to form a contact angle, the interfacial molecular forces determine the geometry of a droplet resonator. Dramatic mechanical changes at the interface play a significant role in the optical oscillation of droplet resonators.

Researchers recently demonstrated a novel technique: plasma-grating-induced breakdown spectroscopy (GIBS).

A study of a giant impact crater on Venus suggests that its lithosphere was too thick to have had Earth-like plate tectonics, at least for much of the past billion years.

Global circulating winds can carry bacteria, fungal spores, viruses and pollen over long distances and across national borders, but the United States is ill-prepared to confront future disease outbreaks or food-supply threats caused by airborne organisms, says a new article.

Ceramic matrix composites (CMCs) are incredibly strong materials used in jet engines, gas turbines, and cutting tools for nickel superalloys. Aluminum oxide (Al2O3) is hard and chemically inert, and tungsten carbide (WC) is used as a superhard material, but past efforts to create an Al2O3-WC CMC yielded unsatisfactory results. Recently, a study by Japanese scientists shows that adding zirconium...

Researchers find a disproportionate number of inmates with violent offenses suffer from post-traumatic stress disorder, panic disorder and alcohol use disorder.

They may be the youngest astronomers to make a discovery yet. This week, a 16-year-old and an 18-year-old have co-authored a peer-reviewed paper describing the discovery of four new exoplanets about 200-light-years away from Earth.

When males have to fight for reproductive rights, having larger weapons such as horns gives them an edge. However, this can also limit their mobility, making them more vulnerable to predators. In a recent study, scientists demonstrated that males of a species adopt different anti-predator tactics -- tonic immobility or escape -- based on the size of their weapons, opening doors to a better...

Scientists have discovered how a protein called Tip60 plays a vital role in the renewal of blood cells in the body. Without it, the stem cells that make new blood suffer catastrophic damage. This discovery could lead to better treatments for life-threatening blood-related diseases like leukemia.

Expert computer programmers show higher proficiency in certain behavioral and attention skills than their novice peers. To identify the responsible brain regions, scientists used fMRI to analyze the brain activities of 30 programmers of different skill level, finding that seven regions of the frontal, parietal and temporal cortices in expert programmers' brains are fine-tuned for programming. The...
