Discovery of Magnetic Field That Can Flip Heat Flow

Josephson-heat-interferometer

Scientists discovered a magnetic field that can control the flow of heat from one body to another. It was first predicted 50 years ago, and its effect could someday lead to a new generation of electronic devices that use heat rather than charge to carry information. The scientists published their findings in the journal Nature. […]

H5N1 Work Will Probably Continue

h5n1-virus-wu

After a high-level meeting this week, work on the avian influenza H5N1 virus will probably continue by people who are not NIH funded. This is in the wake of a global debate about the risks and benefits of such research and a voluntary moratorium on the experiments lasting nearly a year. Experts met on Monday […]

Physicists Induce Electric Currents in Insulating Dielectric Materials

nanometric thin silica-glass film

A team of physicists at the Max Planck Institute have shown that ultrashort light pulses of extremely high intensity can induce electric currents in otherwise insulating dielectric materials, turning fused silica (quartz) from an insulator to a conductor and back again within quadrillionths of a second. Semiconductor components form the backbone of all kinds of […]

Higgs Duality: Contradictory Results At LHC

ATLAS-higgs-boson-CERN

The latest data presented by scientists on Higgs boson shows that separate measurements of its properties are showing two slightly different masses. The scientists at the LHC, CERN, presented their latest data with this duality problem. Since last July, when evidence indicating that the Higgs boson had been discovered was revealed, scientists have been probing […]

Fracking Wastewater Injection Wells Linked to Earthquakes

hydrofracking-USA

Scientists presented evidence tying the disposal of wastewater from shale gas hydrofracking to an increased occurrence of earthquakes. The scientists presented their findings at the American Geophysical Union fall meeting. Some US states, like Oklahoma, Texas, and Colorado have experienced a significant rise in seismic activity in the last few years, coinciding with a recent […]

Zeta Ophiuchi, 80,000 Times Brighter Than the Sun and Traveling at 54,000 MPH

Zeta Ophiuchi

NASA’s Spitzer Space Telescope captured an image of Zeta Ophiuchi, a star that is traveling at 54,000 mph and is about six times hotter, eight times wider, 20 times more massive, and 80,000 times brighter than the Sun. The giant star Zeta Ophiuchi is having a “shocking” effect on the surrounding dust clouds in this […]

Spider Building Spider Decoys Discovered in Peruvian Amazon

cyclosa-building-decoy-spider-torres

Discovered at the Tambopata Research Center in the Peruvian Amazon, a spider belonging to the genus Cyclosa is capable of producing elaborate, fake spider decoys. It hangs them in its own web and shakes the web, furthering the illusion. The spider is believed to be a new species, and crafts a larger spider from leaves, debris […]

“Iron-Rich Blobs” Penetrate Deep into Earth’s Mantle

penetration of molten iron into the mantle caused by a morphological instability

In a lab experiment, Yale researchers discovered that molten iron can deeply penetrate single crystals of magnesium iron oxide, resulting in “metal-rich blobs” that penetrate Earth’s mantle in larger amounts and deeper than previously thought possible. New research by Yale University scientists suggests an explanation for the amount of iron in the Earth’s largest interior […]

Survey Reveals “Ultramassive” Black Holes Weighing 40 billion Times the Mass of the Sun

A galaxy cluster about 1.3 billion light years from Earth with a large elliptical galaxy in its center.

A new survey of 18 giant black holes shows that biggest black holes may be even bigger than previously thought, with several weighing between 10 and 40 billion times the mass of the sun. The black hole at the center of this galaxy is part of a survey of 18 of the biggest black holes […]
