ESO's VISTA telescope spies hidden Milky Way component

An international team of astronomers has discovered a previously unknown component of the Milky Way – a thin disk of variable stars hidden in the galactic bulge. The observations, made using the ESO's Visible and Infrared Survey Telescope for Astronomy (VISTA) telescope conflict with current theories regarding the composition of the center of our galaxy.Read More

Sonic tractor beam forms acoustic holograms to lift objects

Last year, researchers at the University of Dundee revealed an acoustic tractor beam that used ultrasonic energy to pull macroscopic objects in. Now researchers in the UK have developed a sonic tractor beam that generates acoustic holograms through the manipulation of high-amplitude sound waves. These acoustic holograms, which can take various shapes, such as fingers, cages and vortexes, are able to pick up and move small objects like polystyrene beads.Read More

Luxor 2 flashlight automatically detects targets, adjusts beam for ideal illumination

Although most modern flashlights provide the means to adjust beam focus and brightness, very few are equally effective at both flood- and spot-lighting. You could own one of each flashlight type, but the latest from PLX Devices takes a different approach. Not only is the Luxor 2 designed for optimal light delivery, it does so automatically by detecting where it's being pointed in order to adjust the beam accordingly. Read More

Dawn begins transitioning to its fourth and final mapping orbit

NASA's Dawn spacecraft has begun the process of transferring to its fourth and final mapping orbit, as it continues its mission around the dwarf planet Ceres. Dawn initially made orbit around Ceres on Mar. 6, and since then has provided us with increasingly detailed images and data, unlocking many of the mysteries harbored by the enigmatic celestial body.Read More

Study suggests an even distribution of elements throughout the universe

A new study carried out by the Japan Aerospace Exploration Agency (JAXA) suggests that when the universe was between two to four billion years old, the elements used to create everything from the largest star to the human race were evenly spread across a vast area of the cosmos. The study focused on an enormous structure of galaxies known as the Virgo Galaxy Cluster, which sits roughly 54 million light years from Earth and harbors over 2,000 galaxies.Read More

New and unusual phase of matter could shed light on high-temperature superconductivity

Physicists working at the California Institute of Technology (Caltech) have discovered a new phase of matter with a highly unusual arrangement of electrons that could see the creation of innovative electronic devices with novel functionalities never before considered. Not quantifiable as a conventional metal, an insulator, or a type of magnet, this previously unknown state may also help answer a range of fundamental questions in the field of "high-temperature" superconductivity.Read More

Insulin releasing patch draws oral diabetes treatments closer

Of the hundreds of million people around the world that suffer from diabetes, a sizeable portion need to subject themselves to daily insulin injections. But a more palatable way of keeping blood glucose levels in check may be on the way, with scientists developing a patch that attaches to the intestinal wall and releases the hormone after being swallowed in the form of a capsule.

Boozy comet Lovejoy houses building blocks for life

Astronomers have discovered large quantities of alcohol and sugar, as well as the presence of complex organic molocules, on the comet Lovejoy. The observations, made by the 30 meter (98 ft) radio telescope at Pico Veleta, Spain, support the theory that comets may have played an important role in the formation of life on Earth.
