Data Shows 2010 Amazon Megadrought Caused Serious Devastation

A new study indicates that the megadrought that struck the Amazon in 2010 devastated millions of hectares of rainforest, shedding a new light over the debate over the effects of recent climatic events. The initial findings were presented at the fall meeting of the American Geophysical Union. They indicate that as many as one in […]

Pressure Can Revert and Stop the Growth of Cancer Cells

New research showed that applying physical pressure to malignant breast cancer cells guided them back to a normal growth pattern. This research could lead to new treatments. Berkeley — Researchers at the UC Berkeley and the Lawrence Berkeley National Laboratory have put the squeeze — literally — on malignant mammary cells to guide them back […]

Why People Like Watching the Same Thing Over and Over Again

reconsumption-mind

There’s a reason why people are spending money on television show DVDs and Blu rays that are essentially reruns, but this behavior is more complicated than previously thought. Cristel Antonia Russell, a marketing professor at American University, and Sidney J. Levy, a marketing professor at the University of Arizona, published their findings in the Journal […]

Hubble Data Reveals That Globular Clusters Age at Different Rates

Using data from the Hubble Space Telescope, scientists discovered that globular clusters of the same age can have dramatically different distributions of blue straggler stars within them, suggesting that clusters can age at substantially different rates. Some people are in great shape at the age of 90, while others are decrepit before they’re 50. We […]

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

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 […]

New Cassini Image of Saturn and its Rings

NASA’s Cassini spacecraft has delivered new backlit image of the Saturn and its rings. Pasadena, California — Just in time for the holidays, NASA’s Cassini spacecraft, in orbit around Saturn for more than eight years now, has delivered another glorious, backlit view of the planet Saturn and its rings. On October 17, 2012, during its […]

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

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 […]

Liquid Metal Used in Ultra-Stretchable Conducting Wires

Researchers at the North Carolina State University have created conductive wires that are made out of liquid metal, with the ability to stretch eight times their original length, without compromising their basic functionality. These wires could be used in headphones as well as phone chargers. The scientists published their findings in the journal Advanced Functional […]
