Scientists have accidentally discovered a particle that has mass when traveling in one direction, but no mass while moving in a different direction. Known as semi-Dirac fermions, particles with this bizarre behavior were first predicted 16 years ago.

Binge-drinking in early adult years fundamentally changes how brain neurons communicate, in what scientists equate to a faulty gas pedal in a car that needs more pressure applied to "go." This type of dysfunction is also seen in Alzheimer's disease.

Aliens might be able to detect us from the radio signals we beam to Mars to control our rovers there. Astronomers have now listened in on the nearby TRAPPIST-1 system to check whether aliens are chattering between their own neighboring planets.

When it comes to life expectancy in high-income English-speaking countries, a new study has found that America has sat in last place since 2001. Australia remains the best performer and, the researchers say, should serve as a model for how the US can do better.

Researchers have identified an enzyme that's key to updating existing memories with new information, a process that declines naturally with age. Blocking the enzyme reduced memory impairment, opening the door to developing treatments for age-related memory problems.

A new technique may make it easier to selectively breed crop plants for better, deeper roots. The non-destructive process involves quickly checking a plant's leaves to see how far down its roots go into the soil.

In many cases nature has better versions of our tech. The newest example comes from a common insect in your backyard, which makes nanoscale soccer balls that hide it from predators – inspiring new, better UV protection and maybe even cloaking tech.

In a world first, researchers have printed multi-layered, living skin directly onto significant injuries in rats for scar-free skin repair. It's not sci-fi – they're genuinely 3D-printing skin (and possibly hair) right into damaged areas.

While chocolate will likely never be an overall healthy food, it would be good if there could at least be a lower-sugar version of it that people liked just as much as the real thing. Well, it turns out that oat flour could help make that happen.

Smartphones versus personal computers. One tends to be used more for ‘play,’ while the other is favored for work. A new study has found that the way we process deceptive online information very much depends on the device we’re using to view it.

Researchers have uncovered a protein that facilitates the spread of breast cancer cells into healthy tissue. The discovery improves our understanding of the metastatic process and is the first step to developing treatments that target this mechanism.

Let's face it: food that tastes delicious is usually bad for us. But new research shows that a simple preparation trick can dramatically slash fat, sodium and added sugars while making foods like brownies and meatloaf taste just as good.
