ALMA Reveals the Mystery of Missing Massive Galaxies

Starburst Data Sheds New Light on the Mystery of Missing Massive Galaxies

Using data from the ALMA telescope, astronomers shed new light on galaxy formation, finding evidence that some growing galaxies spew out more gas than they take in. New observations from the ALMA telescope in Chile have given astronomers the best view yet of how vigorous star formation can blast gas out of a galaxy and […]

Astrophysicists Document the Immense Power of Quasar Radiation

Dartmouth Researchers Shed New Light on Quasars

Using data from the Southern African Large Telescope and NASA’s WISE, astrophysicists documented the immense power of quasar radiation, seeing for the first time the actual extent to which these quasars and their black holes can affect their galaxies. Quasars are among the brightest, oldest, most distant, and most powerful objects in the universe. Powered […]

New Research Explains Acceleration of Greenland’s Inland Ice

Surprising Acceleration of Greenlands Inland Ice

By developing a new model investigate the effects of meltwater on Greenland glaciers, researchers discovered that meltwater warms the ice sheet, which then softens, deforms, and flows faster. This animation shows how ice is naturally transported from interior topographic divides to the coast via glaciers. The colors represent the speed of ice flow, with areas […]

Enhanced Hollow-Core Fiber Features Performance-Enabling Properties

Hollow Core Optical Fiber to Enable High Power Sensors

Researchers from Honeywell International have modified hollow-core fiber, dramatically improving performance and making it the first hollow-core fiber to demonstrate single-spatial-mode, low-loss and polarization control. The intensity of light that propagates through glass optical fiber is fundamentally limited by the glass itself. A novel fiber design using a hollow, air-filled core removes this limitation and […]

Researchers Link Genetic Mutation to Severe Obesity

Genetic Mutation Linked to Severe Obesity

Researchers have identified a genetic cause of severe obesity, finding that mice with the genetic mutation gained weight even while eating the same amount of food as their normal counterparts. Harvard Medical School researchers at Boston Children’s Hospital have identified a genetic cause of severe obesity that, though rare, raises new questions about weight gain […]

Spitzer Views Gas Emissions From Comet ISON

Spitzer Views Gas Emission From ISON

Using NASA’s Spitzer Space Telescope, astronomers observed gas emissions from Comet ISON, estimating that ISON is emitting about 1 million kilograms of what is most likely carbon dioxide gas and about 54.4 million kilograms of dust every day. Pasadena, California — Astronomers using NASA’s Spitzer Space Telescope have observed what most likely are strong carbon […]

Martian Valleys Likely Caused by Ancient Snowfall or Rain

Ancient Snowfall Likely Caused Water Carved Valley on Mars

In a new study, scientists from Brown University suggest that certain valleys on Mars appear to have been caused by runoff from orographic precipitation. Providence, Rhode Island (Brown University) — Valley networks branching across the Martian surface leave little doubt that water once flowed on the Red Planet. But where that ancient water came from […]

Hubble’s View of Stephan’s Quintet

Hubble Views Hickson Compact Group 92

This popular image from the Hubble Space Telescope shows Stephan’s Quintet. NGC 7320 is 40 million light-years from Earth and the other four members of the quintet reside 290 million light-years away in the constellation Pegasus. A clash among members of a famous galaxy quintet reveals an assortment of stars across a wide color range, […]

New Technique Allows Researchers to Control Genes with Light

New Technique Can Rapidly Turn Genes On and Off

A team of researchers from MIT and the Broad Institute have developed new technology based on optogenetics that allows scientists to start or stop the expression of any genes by simply shining light on the cells. Although human cells have an estimated 20,000 genes, only a fraction of those are turned on at any given […]

Resveratrol Blocks the Positive Effects of Exercise Training

Resveratrol Blocks the Positive Effects of Exercise Training

A new study from the University of Copenhagen revealed that eating a diet rich in antioxidants may actually counteract many of the health benefits of exercise, including reduced blood pressure and cholesterol in older men. In older men, a natural antioxidant compound found in red grapes and other plants – called resveratrol – blocks many […]

GERDA Experiment Phase I Results – No New Evidence That Neutrinos Are Their Own Antiparticles

GERDA Experiment Supplies No New Evidence That Neutrinos Are Their Own Antiparticles

The phase I results from the GERDA experiment have revealed no signal of neutrino-less double beta decay in Ge-76, ruling out an earlier claim for a signal by others. Neutrinos are the most elusive particles having extremely weak interactions with all other particles. They have rather unusual properties and are even expected to be identical […]

Planets Orbiting Cooler Stars May Be More Likely to Remain Ice Free

New Climate Model Research Suggests Planets Orbiting Cooler Stars Are Likely to Remain Ice Free

New climate model research from astronomers at the University of Washington suggests that planets orbiting cooler stars may be more likely to remain ice-free than planets around hotter star due to the interaction of a star’s light with ice and snow on the planet’s surface. Stars emit different types of light. Hotter stars emit high-energy […]
