Astronomers discover massive galaxy cluster 8.5 billion light-years from Earth

Astronomers have discovered a massive galaxy cluster located an impressive 8.5 billion light-years from Earth. It is hoped that further analysis of the cluster, which has been imaginatively named Massive Overdense Object (MOO) J1142+1527 (MOO J1142+1527), will allow scientists to shed some light on the evolution of some of the largest structures in our Universe.Read More

Fraunhofer device could be a surgeon's third arm

Being a surgeon is a pretty high-stress job, and relies heavily on surgical assistants for things like setting clamps and holding tools. Researchers from Germany's Fraunhofer Institute are looking to lighten the load a little, by developing a metal hand that lets surgeons more directly control what's happening on the operating table.Read More

AirBolt travel lock offers smart features and keyless access

To some, air travel is a carefree jaunt without a single ripple in the experience. But to others, it can feel like rushing through a gauntlet of checklists, lines, and gates, with the potential for impromptu anxiety at any given moment. One company is looking to make the luggage-laden travel process a little bit easier with the AirBolt smart travel lock, which is designed with Bluetooth connectivity and a host of useful functions to keep bags secure and accounted for.Read More

NASA releases stunning 30 minute 4K video of the Sun

NASA has released a half hour video of our Sun in breathtaking 4K detail. The video was created from images and data captured by the agency's Solar Dynamics Observatory (SDO) as it continues its mission to observe solar activity and unlock the mysteries surrounding the interior mechanics of our parent star.Read More

Boron-doped graphene to enable ultrasensitive gas sensors

As an atom-thick, two-dimensional material with high conductivity, graphene is set to enable a stream of new electronic devices, including particularly sensitive sensors for the detection of various gases, such as those produced by explosives. Now an international team of researchers led by Pennsylvania State University (Penn State) has created a graphene-boron amalgam that can detect particular gases down to mere parts per billion, and may eventually lead to detectors with such sensitivity that they could detect infinitesimally tiny amounts of gas in the order of parts per quadrillion.Read More

Material that could revolutionize memory storage is magnetic, but not as we know it

Using a type of magnetic insulator material that normally doesn’t conduct electricity, scientists working at Stanford University and the Department of Energy’s SLAC National Accelerator Laboratory have shown that electric currents can still be made to flow along the borders of the grains within the material. This latest research not only validates a long-held belief that magnetic insulators could be used to conduct electricity, but offers a more tantalizing possibility of creating highly-efficient magnetic memory devices.

Claimed darkening of ice sheet could actually be down to aging satellite sensors

In recent years, satellite photos of Greenland's ice sheet have shown what appears to be a darkening of the ice's surface. A number of scientists have suggested that this could be due to settled soot particles from fossil fuel production and/or forest fires, and that their presence could result in accelerated melting of the ice. Now, however, researchers from Dartmouth College believe that the ice may still still be relatively clean, and that its darkness in the photos could just be due to faulty sensors on the satellites.Read More
