Can we observe Earth-like exoplanets from our own planet?

Finding Earth-like planets orbiting sun-like stars and identifying signs of life such as oxygen or water is a major goal in astronomy and a key interest for the public. Addressing this challenge speaks directly to one of humanity's most fundamental questions: Are we alone in

A new 'molecular switch' for inborn immunity identified

Innate immune sensors—known as pattern recognition receptors (PRRs)—detect specific molecular components of bacterial or viral intruders. The PRRs forward the signals which results in the production of interferons, which in turn guide the immune cells. However, until now the

Meet 'Tous'—an entirely new genus of mammal

Mammals are not especially diverse. Roughly 6,800 mammal species are known to exist, compared with about 8,800 species of amphibian, 11,000 species of bird and 12,500 of reptile. Yet when most people picture biodiversity, they often think of charismatic mammals first: pandas,

NASA rules out asteroid smashup on the moon in 2032

Here's one less thing to worry about—or to look forward to: NASA has ruled out any chance that an asteroid called 2024 YR4 will hit the moon in 2032. Last year, the uncertainty surrounding the space rock's orbital path held out a slight chance of impact, but fresh observations

X-raying rocks reveals their carbon-storing capacity

To avoid the worst effects of climate change, many billions of metric tons of industrially generated carbon dioxide will have to be captured and stored away by the end of this century. One place to store such an enormous amount of greenhouse gas is in Earth itself. If carbon

The secret to guessing more accurately with maths

What do a 20th-century physicist, an 18th-century statistician and an ancient Greek philosopher have in common? They all knew how to extrapolate with incredible accuracy. Columnist Jacob Aron explains how to combine their methods to improve your ability to guess
