Meet Zoe - a virtual talking head capable of expressing human emotions

The University of Cambridge in the United Kingdom has unveiled a virtual “talking head” that is capable of expressing a range of human emotions. The team believes that the lifelike face, called Zoe, is the most expressive controllable avatar ever created, and could one day be used as a digital personal assistant.  Read More

Beer salvaged from a shipwreck will be reproduced using modern industrial methods (Photo: ...

Produced at least as far back as 5,000 BC, beer has been with us for a long time. But coming third only to water and tea in terms of worldwide popularity means that the lifespan of individual beers is more likely to be measured in days or weeks rather than years or decades. The exception is if they’re preserved at the bottom of the Baltic Sea in a shipwreck. One such shipwrecked beer that is about 170 years old has been salvaged and analyzed and will be reproduced using modern industrial techniques.  Read More

Scientists have replicated the flexible-but-tough internal structure of the sea sponge, to...

Chances are that if you were heading into battle, you wouldn’t wish that you were covered in sponges. It turns out that the sea sponge, however, has a unique structure that allows it to be flexible while remaining relatively impervious to predators. Scientists have now simulated this structure, in a lab-created material that may someday find use in body armor.  Read More

New research funded by the National Institute for Health Research (NIHR) Biomedical Research Centre and King's College London, UK, may result in bio-engineered replacement teeth which are generated from a person’s own gum cells. Though artificial whole-tooth implants are currently available to people who are missing a tooth, such implants are unable to fully reproduce the natural root structure of a tooth. This means that in time, friction caused by eating and other movement of the jaw can result in a loss of jaw bone.  Read More

An artist’s impression of the gastric-brooding frog that was cloned by scientists working ...

Australian scientists have successfully revived and reactivated the genome of an extinct frog. The "Lazarus Project" team implanted cell nuclei from tissues collected in the 1970s and kept in a conventional deep freezer for 40 years into donor eggs from a distantly-related frog. Some of the eggs spontaneously began to divide and grow to early embryo stage with tests confirming the dividing cells contained genetic material from the extinct frog.  Read More

Using the technique that created Dolly the sheep, researchers from the RIKEN Center for Developmental Biology in Kobe, Japan, have identified a way to produce healthy mouse clones that live a normal lifespan and can be sequentially cloned indefinitely. In an experiment that started in 2005, the team led by Dr. Teruhiko Wakayama has used a technique called somatic cell nuclear transfer (SNCT) to produce 581 clones of one original "donor" mouse through 25 consecutive rounds of cloning.  Read More

Artist's conception of WISE J1049-5319, with the brightly shining Sun 6.5 light years away...

In a day when we have examined astronomical objects shining forth from a time shortly after the Big Bang, one would think astronomers have a pretty good handle on what is in the immediate vicinity of the Solar System. That's why the recent report of a binary star lying only 6.5 light-years away came as rather a surprise to the astronomical community. The pair, called WISE J1049-5319 A and B, are brown dwarf stars and only two star systems – the triple star Alpha Centauri, and Barnard's Star – lie closer to our Sun.  Read More

The speed of entanglement dynamics is at least 10,000 times faster than light according to...

Quantum entanglement, one of the odder aspects of quantum theory, links the properties of particles even when they are separated by large distances. When a property of one of a pair of entangled particles is measured, the other "immediately" settles down into a state compatible with that measurement. So how fast is "immediately"? According to research by Prof. Juan Yin and colleagues at the University of Science and Technology of China in Shanghai, the lower limit to the speed associated with entanglement dynamics – or "spooky action at a distance" – is at least 10,000 times faster than light.  Read More

Researchers at Yale University have now found a molecular switch that can give an adult br...

It’s no secret that juvenile brains are more malleable and able to learn new things faster than adult ones – just ask any adult who has tried to learn a new language. That malleability also enables younger brains to recover more quickly from trauma. Researchers at Yale University have now found a way to effectively turn back the clock and make an old brain young again.  Read More

Scientists may someday be able to measure a person's stress levels by analyzing compounds ...

Most of us are able to let other people know that we’re stressed, simply by telling them. For people such as those suffering from Alzheimer’s, however, it can be difficult to express such a thought. That’s why UK scientists at Loughborough University and Imperial College London are developing a new test that can determine someone’s stress levels by analyzing their breath.  Read More
