PH3c A Low Mass Planet with a Highly Inconsistent Orbit

Yale astronomers and the Planet Hunter program have discovered a low-mass, low-density planet that has a highly inconsistent orbit time around its sun. The new planet, called PH3c, is located 2,300 light years from Earth and has an atmosphere loaded with hydrogen and helium. The elusive orb nearly avoided detection. This is because PH3c has […]

Existence of Quiet Quasars Confirmed

Using the GTC telescope, astronomers were able to confirm that, apart from the highly energetic and rapidly evolving quasars, there is another population of quasars that evolves slowly. Aeons ago, the universe was different: mergers of galaxies were common and gigantic black holes with masses equivalent to billions of times that of the Sun formed […]

Isolation May Be the Most Effective Way to Reduce Transmission of Ebola

New research led by the Yale School of Public Health shows that isolating 75% of infected individuals in critical condition within four days of symptom onset has a high chance of eliminating the spread of Ebola. Isolating the most severely ill Ebola patients before the fifth day of their illness may be the most effective […]

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, […]

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 […]

Fermi Discovers Signs of Starquakes in Magnetar Storm

Using data from NASA’s Fermi Gamma-ray Space Telescope, astronomers have discovered underlying signals related to the rapid-fire “storm” of high-energy blasts detected in 2009 from a highly magnetized neutron star. Such signals were first identified during the fadeout of rare giant flares produced by magnetars. Over the past 40 years, giant flares have been observed […]

Study Reveals Black Holes Can Block the Formation of New Stars

A new study from Johns Hopkins University reveals that massive black holes spewing out radio-frequency-emitting particles at near-light speed can block formation of new stars in aging galaxies, providing crucial new evidence that it is these jets of “radio-frequency feedback” streaming from mature galaxies’ central black holes that prevent hot free gas from cooling and […]

Yale Engineers Develop a Chip Scale Device That Uses Interaction Free Measurement

Engineers at the Yale School of Engineering & Applied Science have developed a chip-scale device that uses the wave-particle duality of single photons to sense the presence of an object without interacting with it – a technique known as “interaction-free measurement.” “Our device uses silicon photonics to create interaction-free measurement on an integrated chip—something previously […]

Saturn Moon Mimas May Have a Fossil Core or an Ocean

New data from NASA’s Cassini Spacecraft reveal that Saturn’s moon Mimas may have a liquid water ocean beneath the moon’s impact-battered surface. A new study focused on the interior of Saturn’s icy moon Mimas suggests its cratered surface hides one of two intriguing possibilities: Either the moon’s frozen core is shaped something like a football, […]

Study Questions 21 Day Quarantine For Ebola

A new study from Drexel University suggests that 21 days might not be enough to completely prevent spread of Ebola, revealing that there could be up to a 12 percent chance that someone could be infected even after the 21-day quarantine. As medical personnel and public health officials are responding to the first reported cases […]

APEX Reveals Star Formation in Unexpected Places

A team of astronomers used the APEX telescope to probe the Spiderweb Cluster, revealing that much of the star formation taking place is hidden by dust and occurring in unexpected places. Galaxy clusters are the largest objects in the Universe held together by gravity but their formation is not well understood. The Spiderweb Galaxy (formally […]

Herschel Views the Debris Disc of Solar Analogue Tau Ceti

Astronomers from the Harvard-Smithsonian Center for Astrophysics studied the debris disc around τ Ceti, revealing that a Jupiter-mass planet could not be present in this system – making it less than ideal as a Solar system analog. Although thousands of exoplanets and hundreds of planetary systems (stars with multiple exoplanets) are now known, astronomers still […]
