Scientists Create New Bio-Ink for 3D Printing

Scientists from University of Bristol have found a new bio-ink for 3D printing with stem cells that allows printing of living tissue known as bio-printing. The new bio-ink contains two different polymer components: a natural polymer extracted from seaweed and a sacrificial synthetic polymer used in the medical industry. “Designing …

MIT Develops AI-Based System That Adds Sound to Silent Videos

MIT researchers have developed a computer system that independently adds realistic sounds to silent videos. Although the technology is nascent, it’s a step toward automating sound effects for movies. In a series of videos of drumsticks striking things – including sidewalks, grass and metal surfaces – the computer learned to …

Hands-Free Phone Use by Drivers Is Just as Distracting as Holding It: Study

Drivers using a hands-free phone get just as distracted as those holding it in their hand, British researchers have found. Scientists at the University of Sussex found telephone conversations while driving can cause the driver to visually imagine what they are talking about. This uses a part of the brain …

Violent Young Sun May Have Seeded Life on Earth: Study

Life on Earth may have sprung from bombardment by a youthful Sun lashing out with flares as potent as a thousand trillion exploding atomic bombs, a study suggested on Monday. Such violence may explain how Earth became hospitable to life about four billion years ago, when the planet, and its …

Curiosity Measures Seasonal Patterns in Mars Atmosphere

The local atmosphere in Mars is clear in winter, dustier in spring and summer, and windy in autumn, show measurements by Nasa’s Curiosity rover that has completed recording environmental patterns through two full cycles of Martian seasons. Curiosity this week completed its second Martian year since landing inside Gale Crater …

Astronomers Find a Tailless Comet, First of Its Kind

Astronomers have found a first-of-its-kind tailless comet whose composition may offer clues into long-standing questions about the solar system’s formation and evolution, according to researchpublished on Friday in the journal Science Advances. The so-called “Manx” comet, named after a breed of cats without tails, was made of rocky materials that …

Scientists Record Heat Moving Through Materials at Speed of Sound

Providing unprecedented insight into roles played by individual atomic and nano-scale features, researchers have recorded the first-ever videos showing how heat moves through materials at the nano-scale travelling at the speed of sound. The groundbreaking videos were made using a state-of-the-art ultrafast electron microscope called FEI Tecnai Femto, which is …

Scientists Discover Hot Super-Earths Being Stripped by Host Stars

Using data from Nasa’s Kepler space telescope, astrophysicists from the University of Birmingham have discovered extra-solar planets whose atmospheres have been stripped away by their host stars. According to them, planets with gaseous atmospheres that lie very close to their host stars are bombarded by a torrent of high-energy radiation. …
