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.

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, and likely shaped the composition of the solar system's infant planets.

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 communities -- with unforeseeable consequences for marine food webs.

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 dataset is publicly available online.

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 ultrafast demagnetization remain unclear. Now, a team has developed a new method at BESSY II to quantify one of these mechanisms and applied it to the...

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 those patients also is associated with an increased risk of cardiovascular events. Getting the influenza vaccine, however, substantially reduces...
