Researchers from Russia, Finland, and the U.S. have put a constraint on the theoretical model of dark matter particles by analyzing data from astronomical observations of active galactic nuclei. The new findings provide ...

Lizards can regrow entire limbs. Flatworms, starfish, and sea cucumbers regrow entire bodies. Sharks constantly replace lost teeth, often growing over 20,000 teeth throughout their lifetimes. How can we translate these n...

The findings support a continuous model of neurogenesis throughout development and adulthood.

When you think of an aerodynamic car, what comes to mind? Smooth curves, sharp points, images of smoke streaming over surfaces in a wind tunnel--but what if we didn't have to change something's shape to help it cut throu...

Molecular machinery to make synthetic proteins has been added to human cells in the lab. Next: animals and plants with artificial factories in every cell

The deadly disease caused by chytrid fungus is now thought to have driven nearly 100 amphibian species to extinction and contributed to the decline of over 400 more

In the future, ultrahigh-speed spintronics will require ultrafast coherent magnetization reversal within a picosecond--one-trillionth of a second. Spintronics centers on an electron's spin and magnetic moment in solid-st...

Texas A&M University researchers are looking to nature for inspiration in developing a new method of underwater plasma generation using shrimp as a model--a discovery that could provide significant improvements for actio...

Lanthanum, diamond crushers and advanced computer models are changing the hunt for this extreme quantum mechanical effect.

Ali Atar's sword lives at the Toledo Army Museum in Spain, but you can now see it online in 3D

Lions in the important Kavango-Zambezi conservation area may be less able to adapt to climate change due to a loss of genetic variation over the past century

Video games and physics have more in common than you might think. Freya Blekman, a professor of physics at Vrije Universiteit Brussel in Belgium, has a special chair for when she plays Starcraft. "It's a designer chair,"...

EVERY DAY between 100 and 600 tonnes of rock hurtles into Earth's atmosphere. The reason so little of this bombardment makes it to the planet's surface is that much of it is burnt up by atmospheric friction, which create...

HIPPOCRATES, GALEN, Avicenna and other ancient physicians frequently used odour as a diagnostic tool. Although scent is not used nearly as often in modern medicine, it still has its place. Paramedics are routinely taught...

WHEN SOME plants are attacked by herbivores they fight back by producing irritants and toxins as their leaves get chewed up. Certain insects, however, can resist these defences. Among the best at doing this, and hence on...

EVEN THOUGH solar panels have improved over the years they are still not very efficient at doing their job. Standard panels using silicon-based solar cells typically convert 17-19% of the sun's energy into electricity. I...

The number of antidepressant prescriptions dispensed in England exceeded 70 million in 2018. This is almost double the number dispensed a decade ago

A team of researchers from JTEC Corporation and Osaka University developed a bimorph deformable mirror that allows for precise shape modification and usage under vacuum, a world first.

Service dogs for people with epilepsy can tell when their owners are having a seizure, but we don't know how. Now an experiment suggests they can smell seizures

A quasiparticle is a disturbance or excitation (e.g. spin waves, bubbles, etc.) that behaves as a particle and could therefore be regarded as one. Long-range interactions between quasiparticles can give rise to a 'drag,'...

Physicists recently investigated the behavior of particles in a dusty plasma at a temperature below 2 degrees K. The experiment showed that at extremely low temperatures, nanoclusters can form in the plasma, and the synt...

Human bodies have some built-in systems to care for themselves. The cells that line our lungs, nose, brain and reproductive system have cilia, which are tiny, hair-like structures designed to sweep out fluids, cells and ...
