Rutgers Study Shows Previous Climate Change Was Caused by the Ocean and the Atmosphere

Past Climate Change Was Caused by the Ocean and Atmosphere

New research from Rutgers University provides a deeper understanding of the mechanisms of climate change, revealing that circulation of the ocean plays an important role in regulating the climate. Most of the concerns about climate change have focused on the amount of greenhouse gases that have been released into the atmosphere. But in a new […]

Dietary Cocoa Flavanols Reverse Age-Related Memory Decline in Older Adults

Dietary Cocoa Flavanols Reverse Age-Related Memory Decline in Healthy Older Adults

A new study from Columbia University Medical Center shows that dietary cocoa flavanols reverse age-related memory decline in healthy older adults. New York, New York — Dietary cocoa flavanols—naturally occurring bioactives found in cocoa—reversed age-related memory decline in healthy older adults, according to a study led by Columbia University Medical Center (CUMC) scientists. The study, […]

Chemists Reveal How Synthetic Collagen Fibers Self-Assemble

How Synthetic Collagen Fibers Self-Assemble

Two new researcher papers from Rice University detail how synthetic collagen fibers self-assemble via their sticky ends. Collagen is the most common protein in mammals, a major component of bone and the fibrous tissues that support cells and hold organs together. Discovering its secrets may lead to better synthetic collagen for tissue engineering and cosmetic […]

Physicists Produce New Evidence for an Exotic Superconducting State

New Evidence for an Exotic Superconducting State

A newly published study led by Brown University reveals new evidence for an exotic superconducting state that can arise when a superconductor is exposed to a strong magnetic field. Providence, Rhode Island (Brown University) — Superconductors and magnetic fields do not usually get along. But a research team led by a Brown University physicist has […]

Cassini Identifies a High-Altitude Methane Ice Cloud on Titan

Researchers Identify an Unexpected High Altitude Methane Ice Cloud on Titan

Using data from NASA’s Cassini spacecraft, astronomers have identified an unexpected high-altitude methane ice cloud on Saturn’s moon Titan that is similar to exotic clouds found far above Earth’s poles. This lofty cloud, imaged by NASA’s Cassini spacecraft, was part of the winter cap of condensation over Titan’s north pole. Now, eight years after spotting […]

Hubble Image of the Week: A Galaxy on the Edge

Hubble Views Galaxy NGC 4762

This Hubble image of the week shows lenticular galaxy NGC 4762, which is located roughly 58 million light-years away. This spectacular image was captured by the NASA/ESA Hubble Space Telescope’s Advanced Camera for Surveys (ACS). The bright streak slicing across the frame is an edge-on view of galaxy NGC 4762, and a number of other […]

Astronomers Discover Two Distinct Families of Exocomets Around Beta Pictoris

Tthe Most Complete Census of Comets Around Another Star

Astronomers make the most complete census of comets around another star, revealing that individual comets orbiting the star Beta Pictoris belong to two distinct families of exocomets. The HARPS instrument at ESO’s La Silla Observatory in Chile has been used to make the most complete census of comets around another star ever created. A French […]

NASA Maps of Titan Reveal Large Patches of Trace Gases

New Maps of Saturn's Moon Titan Reveal Large Patches of Trace Gases

Researchers investigating the chemical make-up of Titan’s atmosphere have discovered large patches of trace gases shining brightly near the north and south poles Saturn’s moon Titan. New maps of Saturn’s moon Titan reveal large patches of trace gases shining brightly near the north and south poles. These regions are curiously shifted off the poles, to […]

Astronomers Create 3D Map of the Distant Universe

A 3D Map of the Adolescent Universe

Using a new technique similar to x-ray computer-tomographic imaging, a team of astronomers has created the first three-dimensional map of the adolescent Universe – just 3 billion years after the Big Bang. Using extremely faint light from galaxies 10.8-billion light years away, scientists have created one of the most complete, three-dimensional maps of a slice […]

Yale Scientists Reveal Ebola Epidemic in Africa Poised to Explode

Yale Study Shows Ebola Epidemic in Africa Poised to Explode

An international team of scientists has developed a new mathematical transmission model of the Ebola disease and applied it to Liberia’s most populous county, revealing that tens of thousands of new Ebola cases and deaths are likely by December 15 if the epidemic continues on its present course. The Ebola virus disease epidemic already devastating […]

New TLP Coating Repels Blood and Bacteria

New Coating for Medical Devices Repels Blood and Bacteria

Using materials already approved by the FDA, Harvard engineers have developed a new surface coating for medical devices that repels blood and suppresses biofilm formation. Most any medical device implanted in the body — or one that comes into contact with flowing blood, such as a dialysis machine — may also present two critical challenges […]
