NSF’s LIGO Detects Gravitational Waves

LIGO Detects Gravitational Waves

Using the Laser Interferometer Gravitational-Wave Observatory (LIGO), the National Science Foundation has detected gravitational waves. Albert Einstein predicted the existence of gravitational waves in his general theory of relativity a century ago, and scientists have been attempting to detect them for 50 years. Einstein pictured these waves as ripples in the fabric of space-time produced […]

Yale Scientists Reveal Underlying Cause of Myeloma

Yale Scientists Discover Underlying Cause of Myeloma

Scientists from the Yale Cancer Center have identified what causes a third of all myelomas, a type of cancer affecting plasma cells. The findings, published February 10 in the New England Journal of Medicine, could fundamentally change the way this cancer and others are treated. Multiple myeloma is a cancer involving the growth of plasma […]

New Yale Study Pinpoints Key Protein in Severe Vascular Disease

Key Protein in Severe Vascular Disease Revealed

New research from Yale University investigates factors that squeeze, or narrow, the aorta in a common vascular disease, revealing a target for potential new treatments. Individuals who suffer from supravalvular aortic stenosis, a condition characterized by narrowing of the aorta, have only one copy instead of the usual two copies of the gene encoding elastin. […]

New Research Shows Long-Term Global Warming Needs External Drivers

New Study Shows Long-Term Global Warming Needs External Drivers

New research from NASA and Duke University provides new evidence that natural cycles alone aren’t sufficient to explain the global atmospheric warming observed over the last century. A study by scientists at NASA’s Jet Propulsion Laboratory in Pasadena, California, and Duke University in Durham, North Carolina, shows, in detail, the reason why global temperatures remain […]

Ices and Shadows – Cassini Views Saturn’s Moon Tethys

New Image of Saturn's Moon Tethys

NASA’s Cassini Spacecraft views Saturn’s moon Tethys. Saturn’s moon Tethys appears to float between two sets of rings in this view from NASA’s Cassini spacecraft, but it’s just a trick of geometry. The rings, which are seen nearly edge-on, are the dark bands above Tethys, while their curving shadows paint the planet at the bottom […]

Scientists Characterize Nerve Cells That Detect Motion by Light Changes

Neurobiologists Characterize Nerve Cells That Detect Motion by Light Changes

In a newly published study, neurobiologists from the Max Planck Institute reveal that (in fruit flies) four classes of nerve cell are involved in calculating directionally selective signals. The ability to see the direction in which something is moving is vital for survival. Only in this way is it possible to avoid predators, capture prey […]

Was Frozen Mammoth or Giant Ground Sloth Served for Dinner?

Yale Researchers Put Prehistoric Mystery Meat to the Test

A famous dinner for scientists in the 1950s supposedly served meat from a woolly mammoth that was discovered frozen in the arctic. Yale scientists obtained a preserved sample of the meat, which DNA analysis proves is actually from a modern green sea turtle. The green sea turtle is an endangered species, so the flesh sample […]

Preliminary Reference Earth Model Shows Earth-like Planets Have Earth-like Interiors

PREM Model Shows Mass-Radius Relation for Rocky Planets

New research from the Harvard-Smithsonian Center for Astrophysics reveals that rocky worlds share similar structures, with a core containing about a third of the planet’s mass, surrounded by a mantle and topped by a thin crust. Every school kid learns the basic structure of the Earth: a thin outer crust, a thick mantle, and a […]

Astronomers Observe Star Formation in the Outskirts of Galaxies

Star Formation in the Outer Spiral Regions of Galaxy NGC 4625

A newly published study from the Harvard-Smithsonian Center for Astrophysics finds that the star formation processes in the outer spiral regions of the galaxy NGC 4625 generally resemble the processes at work in more normal, denser regions where molecular gas abounds. Star formation environments can be roughly grouped into three types, categorized by the density […]

Biologists Extend Lifespan in Mice by 35 Percent

Researchers Extend Lifespan in Mice by as Much as 35 Percent

A team of biologists from the Mayo Clinic have shown that senescent cells – cells that no longer divide and accumulate with age – negatively impact health and shorten lifespan by as much as 35 percent in normal mice. The results, which appear today in Nature, demonstrate that clearance of senescent cells delays tumor formation, […]

New Energy-Friendly Chip Can Perform Powerful AI Tasks

Energy-Friendly Chip Can Perform Powerful AI Tasks

Engineers from MIT have designed a new chip to implement neural networks. It is 10 times as efficient as a mobile GPU, so it could enable mobile devices to run powerful artificial-intelligence algorithms locally, rather than uploading data to the Internet for processing. In recent years, some of the most exciting advances in artificial intelligence […]
