IceCube Collaboration Confirms Cosmic Neutrino Sighting

Evidence for Astrophysical Muon Neutrinos

Using data from the IceCube Neutrino Observatory, scientists have confirmed the existence of astrophysical neutrinos from our galaxy as well as cosmic neutrinos from sources outside the Milky Way. Researchers using the IceCube Neutrino Observatory have sorted through the billions of subatomic particles that zip through its frozen cubic-kilometer-sized detector each year to gather powerful […]

Harvard Researchers Explain the Reason for Genetic Obesity

Researchers Explain the Reason for Genetic Obesity

Researchers from Harvard Medical School and MIT reeval a genetic circuit that controls whether our bodies burn or store fat. Like many other conditions, obesity is caused by an interplay between genetic and environmental factors. While efforts to combat the obesity epidemic will need to include changes in diet and exercise, insights into the genes […]

Scientists Develop New Technique To Improve Kidney Research

Scientists Develop New Technique for Kidney Research

Scientists at Yale School of Medicine have developed a new 3D-imaging technique to better understand and to help treat kidney disease. One in four patients treated with the widely used anti-cancer drug cisplatin develop chronic kidney disease. To better understand how the treatment leads to kidney damage, and possibly prevent it, a team of researchers […]

Astronomers Observe a Long-Hypothesized Mechanism for Coronal Heating

Researchers Observe a Long-Hypothesized Mechanism for Coronal Heating

A team of astronomers has observed a long-hypothesized mechanism for coronal heating in which magnetic waves are converted into heat energy. Modern telescopes and satellites have helped us measure the blazing hot temperatures of the sun from afar. Mostly the temperatures follow a clear pattern: The sun produces energy by fusing hydrogen in its core, […]

UCLA Physicists Use Cold Atoms to Probe Dark Energy

Physicists Use Cold Atoms to Probe Dark Energy

A team of physicists reproduced the low-density conditions of space to precisely measure dark energy, helping to reveal how strongly dark energy interacts with normal matter. Besides the atoms that make up our bodies and all of the objects we encounter in everyday life, the universe also contains mysterious dark matter and dark energy. The […]

ESA’s Herschel Space Observatory Views Cosmic Cloud Mon R2

Herschel Space Observatory Views Feathery Filaments in Mon R2

This new image from ESA’s Herschel space observatory reveals fierce flashes of light rippling through delicate tendrils of gas in the heart of a large and dense cosmic cloud known as Mon R2. This cloud lies some 2700 light-years away and is studded with hot, newly-formed stars. Packed into the bright center of this region […]

ESO Views the Ghost of a Dying Star – Planetary Nebula ESO 378-1

New Image of Planetary Nebula ESO 378-1

A new image from ESO’s Very Large Telescope provides the best view to date of planetary nebula ESO 378-1. This extraordinary bubble, glowing like the ghost of a star in the haunting darkness of space, may appear supernatural and mysterious, but it is a familiar astronomical object: a planetary nebula, the remnants of a dying […]

Calprotectin Plays a Key Role in Blocking Pathogen Survival

Calprotectin Fends off Microbial Invaders

New research from MIT reveals the process by which human calprotectin prevents invading pathogens from obtaining iron. Invading microbial pathogens must scavenge essential nutrients from their host organism in order to survive and replicate. To defend themselves from infection, hosts attempt to block pathogens’ access to these nutrients. Now researchers at MIT have discovered the […]

Yale Engineers Believe Cornstarch Could Lead To Better Protective Gear

Cornstarch Could Lead To Better Protective Gear

New research from the Yale School of Engineering & Applied Science is examining how cornstarch could lead to better protective gear for police, military and athletes. A quick scan of Eric Brown’s laboratory finds all the requisite high-tech equipment and equation-filled whiteboards. More incongruous are the many containers of Argo cornstarch – the same kind […]

Physicists Work on New Approach to Detect Dark Matter

New Approach for Detecting Dark Matter

Physicists are working on a new theory to detect dark matter. They believe that dark matter particles annihilate into “dark radiation” when they collide and that they should be able to detect the signals from this radiation. The majority of the mass in the Universe remains unknown. Despite knowing very little about this dark matter, […]

Jakobshavn Glacier Sheds a Massive Chunk of Ice

Optical Image of Jakobshavn Glacier in Western Greenland Shows Massive Calving Event

New ESA satellite images show that the fastest moving glacier in the world (the Jakobshavn glacier) shed a massive chunk of ice measuring around 12.5 square kilometers – one of the most significant calving events on record. Radar images from Sentinel-1A captured the Jakobshavn glacier in western Greenland before and after the event, which took […]

Astronomers Study Textured Dust Storms on Mars

Dust Storms on Mars

A new analysis of textured dust storms from the Harvard-Smithsonian Center for Astrophysics examines data over eight years of MGS observations and finds that such storms account for about half of all the dust in the Martian atmosphere. In the 1870’s astronomers first noted the presence of yellow clouds on the surface of Mars and […]
