Phys.org / Scientists build 'cell villages' to map the genetics of brain cell fitness

How readily a cell divides and how well it survives are fundamental to life, shaping everything from organ size to the body's ability to withstand disease. That combination, known as cell fitness, isn't the same for everyone. ...

Dialog / How to keep the Earth habitable when the sun dies

In a billion years, the sun will start to run out of fuel and expand to become a red giant. Earth's oceans and atmosphere will be burned away, and Earth will likely be engulfed by the sun altogether. The sun will then shrink ...

Phys.org / Simulations hint at a hidden population of companionless black holes

So far, almost all stellar-mass black holes detected by astronomers have been found in binary systems. However, astronomers have long suspected that these binary black holes are the exception and that, within the Milky Way, ...

Phys.org / New quantum encryption method prevents ciphertext from being cloned

Digital security currently relies on difficult equations to protect data. For example, when you use a credit card online, the information is locked inside a math problem that would take a modern computer thousands of years ...

Phys.org / New models shed light on how an exotic phase of hydrogen in Earth's core may behave

While Earth's core consists mostly of iron, its density implies that lighter elements are also mixed in. Because hydrogen is abundant in the universe and can mix with iron under certain conditions, scientists suspect it makes ...
