Astrocytes, traditionally non-immune cells within the central nervous system, possess the ability to develop an immune memory, responding more vigorously to subsequent immune challenges. This groundbreaking study reveals...

The idea of emergent gravity is still new and requires a lot of assumptions in its calculations to make it work. But if experimental evidence ever proves it real, we would need to totally rewrite the laws of physics.

The wooden vessels were likely used by Neolithic people for fishing and transport.

The turbulent motion of a tumbling river or the outflow from a jet engine is chaotic: that is, it contains no obvious pattern.

Researchers have incorporated a swept illumination source into an open-top light-sheet microscope to enable improved optical sectioning over a larger area of view. The advance makes the technique more practical for nonde...

Microglia, the central nervous system's immune cells, are crucial in helping the brain recover from anesthesia. By interacting directly with brain circuits and inhibitory synapses, microglia work to counteract sedation e...

In a new Nature study, Columbia Engineering researchers have built a photonic chip that is able to produce high-quality, ultra-low-noise microwave signals using only a single laser. The compact device--a chip so small, i...

Headaches are a common and recurring problem in space, even for astronauts that don't experience them on Earth.

The earliest settlers of Rapa Nui, also known as Easter Island, appear to have had some sort of contact with people from South America as early as 1,000 years ago, a new plant study finds.

A dolphin that lived in the Amazon 16 million years ago grew to a length of 3.5 metres - larger than any other freshwater dolphin

Italian canoes capable of transporting people and goods have been dated to the Neolithic period, suggesting there was a bustling trade across the Mediterranean Sea

What is all our screen use really doing to us? Pete Etchells's new book counters the scare stories by sticking to the science, says Chris Stokel-Walker

As DNA testing becomes routine, will life insurance companies start using our genetic code to inform their decisions, asks Jenny Kleeman

A recent paper packed with delightful acronyms digs into where people report having seen UFOs, but finds no evidence of alien visitors, says Annalee Newitz

Pieced together digitally from thousands of images, this shot of last October's annular eclipse, from Andrew McCarthy and Daniel Stein, is a curtain-raiser for next month's total solar eclipse in North America

Feedback is intrigued by new research into how major sports tournaments "were associated with increases in the number of babies born" nine months later - but only for supporters of the winning teams

Topological solitons can be found in many places and at many different length scales. For example, they take the form of kinks in coiled telephone cords and large molecules such as proteins. At a very different scale, a ...

Researchers upended traditional views on motor neurons through their groundbreaking study on fruit flies. Demonstrating that individual motor neurons can produce a variety of complex head movements rather than just simpl...

The already budget-friendly GermGuardian AC4825E air purifier is now even cheaper at Amazon.

Magnetic moment is an intrinsic property of a particle with spin, arising from interaction between the particle and a magnet or other object with a magnetic field. Like mass and electric charge, magnetic moment is one of...

Twin stars that were born together should have the same composition, and the fact that many don't suggests they have changed their chemistry by devouring planets

Evidence from an archaeological site in Ethiopia suggests ancient humans adapted their diet during a dry spell after the Toba volcano eruption 74,000 years ago
