While the onion, garlic, scallion, shallot and chives have been on our plates for centuries, becoming staple foods around the world, their group, the genus Allium, seems to be a long way from running out of surprises. Recently, a group of…
Interviews with two dozen emergency medicine residents in academic medical center found most placed importance on learning to deliver high-quality care to diverse populations. However, many did not feel their programs made enough effort to…
Scientists have gained new insights into the diet, population density and social interactions of a group of Brazilian jaguars.
Researchers found that complex teeth, a hallmark of mammals, also evolved several times in reptiles, prompting the evolutionary success of plant-eating lizards. However, contrary to mammals their tooth evolution was not unidirectional.
When the brain stores memories of objects, it creates a characteristic pattern of activity for each of them. Stress changes such memory traces.
An EPFL scientist has pinpointed the signs of brain activity that make up our brain fingerprint, which -- like our regular fingerprint -- is unique.
In the early solar system, a 'protoplanetary disk' of dust and gas rotated around the sun and eventually coalesced into the planets we know today. A new study suggests that a mysterious gap existed within this disk around 4.567 billion years ago,…
A new data-driven system accelerates the process of discovering 3D printing materials that have multiple mechanical properties.
Researchers have created an atlas of metabolites in the mouse brain. The dataset includes 1,547 different molecules across 10 brain regions in male and female laboratory mice from adolescence through adulthood and into advanced old age. The complete…
Magnetic solids can be demagnetized quickly with a short laser pulse, and there are already so-called HAMR (Heat Assisted Magnetic Recording) memories on the market that function according to this principle. However, the microscopic mechanisms of…
A study involving some 11,000 dogs demonstrated that the gender, age and breed of the dog, as well as any behavioral problems and certain environmental factors, are connected to hyperactive and impulsive behavior and inattention (ADHD).
Patients who have cardiovascular disease are at increased risk of serious complications from the flu, according to a new study. The study found that not only are traditional flu-related outcomes worse among some patients with CVD, but infection in…
Ocean warming caused by anthropogenic greenhouse gas emissions will prompt many species of marine plankton to seek out new habitats, in some cases as a matter of survival. Researchers expect many organisms to head to the poles and form new…
Bacteria can store extra resources for the lean times. It's a bit like keeping a piggy bank or carrying a backup battery pack. One important reserve is known as cyanophycin granules, which were first noticed by an Italian scientist about 150 years…
Researchers have identified a protein that plays a key role in how the brain regulates appetite and metabolism. Loss of the protein, XRN1, from the forebrain, resulted in obese mice with an insatiable appetite, according to a new study.
Between 2016 and 2018, researchers studied wild boar and rat snakes across a range of radiation exposures in Fukushima. The team examined biomarkers of DNA damage and stress and did not find any significant adverse health effects.
