'Stunning' Discovery: Metals Can Heal Themselves

Researchers announce the first observation of a self-healing metal. If harnessed, the newly discovered phenomenon could someday lead to engines, bridges and airplanes that reverse damage caused by wear and tear, making them safer and ...

'Mind Controlling' Parasitic Worms Are Missing Genes Found in Every Other Animal

Parasitic hairworms manipulate the behavior of their hosts in what's sometimes called 'mind control.' A new study reveals another strange trait shared by different hairworm species: they're missing about 30% of the genes that researchers expected ...

Unusual Fossil Shows Rare Evidence of a Mammal Attacking a Dinosaur

Scientists have described an unusual fossil from around 125 million years ago in China that shows a dramatic moment in time when a carnivorous mammal attacked a larger plant-eating dinosaur. The two animals are locked in mortal combat, and it's among the first evidence to show actual predatory ...

Surgical and Engineering Innovations Enable Unprecedented Control Over Every Finger of a Bionic Hand

The Sound of Silence? Researchers Demonstrate People Hear It

Silence might not be deafening but it's something that literally can be heard, concludes a team of philosophers and psychologists who used auditory illusions to reveal how moments of silence distort people's perception of ...

Medical 'Microrobots' Could One Day Treat Bladder Disease, Other Human Illnesses

Engineers have designed a new class of 'microrobots' several times smaller than the width of a human hair that may be able to treat human illnesses like interstitial cystitis -- a painful bladder disease that affects millions of ...

Skin Patch Shows Promise for Toddlers With Peanut Allergy

A global phase 3 clinical trial found that a year-long immunotherapy through a skin patch safely desensitized toddlers with peanut allergy, lowering the risk of a severe allergic reaction from accidental ...

Homo Sapiens Likely Arose from Multiple Closely Related Populations

In testing the genetic material of current populations in Africa and comparing against existing fossil evidence of early Homo sapiens populations there, researchers have uncovered a new model of human evolution -- overturning previous beliefs that a single African population gave rise to all ...

First 'Ghost Particle' Image of Milky Way

Scientists have revealed a uniquely different image of our galaxy by determining the galactic origin of thousands of neutrinos -- invisible 'ghost particles' which exist in great quantities but normally pass straight through Earth undetected. The neutrino-based image of the Milky Way is the first ...

Earliest Strands of the Cosmic Web

Galaxies are not scattered randomly across the universe. They gather together not only into clusters, but into vast interconnected filamentary structures with gigantic barren voids in between. This 'cosmic web' started out tenuous and became more distinct over time as gravity drew matter ...

Gravitational Waves from Colossal Black Holes Found Using 'Cosmic Clocks'

You can't see or feel it, but everything around you -- including your own body -- is slowly shrinking and expanding. It's the weird, spacetime-warping effect of gravitational waves passing through our galaxy. New results are the first evidence of the gravitational wave background -- a sort of soup ...

Air Pollution Particles May Be Cause of Dramatic Drop in Global Insect Numbers

Researchers report that an insect's ability to find food and a mate is reduced when their antennae are contaminated by particulate matter from industry, transport, bushfires, and other sources of air ...

The Ocean's Color Is Changing as a Consequence of Climate Change

The ocean's color has changed significantly in 20 years, and the trend is likely a consequence of human-induced climate change, report ...

Crawford Lake, Canada, Chosen as the Primary Marker to Identify the Start of the Anthropocene Epoch

An international team of researchers has chosen the location which best represents the beginnings of what could be a new geological epoch, the Anthropocene. The Anthropocene Working Group have put forward Crawford Lake, in Canada, as a Global ...

The Ground Is Deforming, and Buildings Aren't Ready
