Four-dimensional printing unfolding as technology that takes 3D printing to an entirely new level Posted: 23 Apr 2015 06:35 PM PDT The fourth dimension is time, shape shifting in fact, and scientists are already working on the next revolution in additive manufacturing.

Second possible specimen of 'pocket shark' ever found Posted: 23 Apr 2015 03:27 PM PDT An extraordinarily rare ocean discovery of an inches-long 'pocket shark' has been made. Sharks come in all shapes and sizes and are best known as a dominant predator in the marine food web. Understanding their movements, behaviors and anatomies gives fishery managers a better idea of their diets and relationships with other species.

Astronomers find runaway galaxies Posted: 23 Apr 2015 12:47 PM PDT We know of about two dozen runaway stars, and have even found one runaway star cluster escaping its galaxy forever. Now, astronomers have spotted 11 runaway galaxies that have been flung out of their homes to wander the void of intergalactic space.

Revolutionary discovery leads to invention of new 'building blocks' Posted: 23 Apr 2015 11:28 AM PDT Taking a revolutionary 'building blocks' approach, a research team has invented a new thinking pathway in the design and synthesis of macromolecules by creating an original class of giant tetrahedra. Through a reaction called 'click chemistry,' these tetrahedron building blocks can then be precisely manipulated to unite with other tetrahedrons.

Scientists see deeper Yellowstone magma Posted: 23 Apr 2015 11:27 AM PDT Seismologists have discovered and made images of a reservoir of hot, partly molten rock 12 to 28 miles beneath the Yellowstone supervolcano, and it is 4.4 times larger than the shallower, long-known magma chamber. The hot rock in the newly discovered, deeper magma reservoir would fill the 1,000-cubic-mile Grand Canyon 11.2 times.

A focus on flight: Birds use just two postures to avoid obstacles during flight Posted: 23 Apr 2015 10:03 AM PDT A new study shows birds use two highly stereotyped postures to avoid obstacles in flight. The study could open the door to new ways to program drones and other unmanned aerial vehicles to avoid similar obstacles.

Differences in personality influence survival in field crickets Posted: 23 Apr 2015 10:03 AM PDT An individual's behaviour in risky situations is a distinct personality trait both in humans and animals that can have an immediate impact on longevity. Researchers have now found differences in personality types for the first time in a population of free living field crickets. Risk-prone individuals showed a higher mortality as they stayed more often outside their burrow where they can be easily detected by predators, compared to risk averse individuals. Moreover, shy individuals are not encountered so often by researchers, causing potential bias in collected scientific data. This methodological problem has been a neglected in many personality studies but has been accounted for uniquely in the present study.

In search of tinnitus, that phantom ringing in the ears Posted: 23 Apr 2015 09:58 AM PDT About one in five people experience tinnitus, the perception of a sound -- often described as ringing -- that isn't really there. Now, researchers have taken advantage of a rare opportunity to record directly from the brain of a person with tinnitus in order to find the brain networks responsible.

Looking to fossils to predict tooth evolution in rodents: Ever-growing molars in the future? Posted: 23 Apr 2015 09:58 AM PDT Fifty million years ago, all rodents had short, stubby molars -- teeth similar to those found in the back of the human mouth, used for grinding food. Over time, rodent teeth progressively evolved to become taller, and some rodent species even evolved continuously growing molar teeth. A new study predicts that most rodent species will have ever-growing molars in the far distant future.

Can sound help us detect 'earthquakes' on Venus? Posted: 23 Apr 2015 09:58 AM PDT Detecting an 'earthquake' on Venus would seem to be an impossible task. But conditions in Venus' atmosphere are much more hospitable, and it is here that researchers hope to deploy an array of balloons or satellites that could detect Venusian seismic activity -- using sound.

Crime scene discovery: Scientist separates the DNA of identical twins Posted: 23 Apr 2015 09:57 AM PDT Since its first use in the 1980s -- a breakthrough dramatized in recent crime-solving dramas -- DNA profiling has been a vital tool for forensic investigators.  Now researchers have solved one of its few limitations by successfully testing a technique for distinguishing between the DNA -- or genetic fingerprint -- of identical twins.

Entire genomes of woolly mammoths mapped: Clues to extinction, possibility of bringing mammoths back Posted: 23 Apr 2015 09:48 AM PDT An international team of researchers has sequenced the nearly complete genome of two Siberian woolly mammoths -- revealing the most complete picture to date -- including new information about the species' evolutionary history and the conditions that led to its mass extinction at the end of the Ice Age.

Scientists create the sensation of invisibility Posted: 23 Apr 2015 07:23 AM PDT The power of invisibility has long fascinated man and inspired the works of many great authors and philosophers. A team of neuroscientists now reports a perceptual illusion of having an invisible body, and show that the feeling of invisibility changes our physical stress response in challenging social situations.

Ultra-sensitive sensor detects individual electrons Posted: 23 Apr 2015 05:52 AM PDT Scientists have created an electronic device so accurate that it can detect the charge of a single electron in less than one microsecond. It has been dubbed the 'gate sensor' and could be applied in quantum computers of the future to read information stored in the charge or spin of a single electron.
