NASA Shows Arctic Sea Ice Is Losing Its Bulwark Against Warming Summers

How Arctic Sea Ice Is Losing Its Bulwark Against Warming Summers

New research shows that the Arctic sea ice has been hit with a double whammy over the past decades: as its extent shrunk, the oldest and thickest ice has either thinned or melted away, leaving the sea ice cap more vulnerable to the warming ocean and atmosphere. “What we’ve seen over the years is that […]

Hubble Admires Youthful Globular Star Cluster NGC 362

Hubble Views Star Cluster NGC 362

This newly released Hubble image shows globular cluster NGC 362. Globular clusters offer some of the most spectacular sights in the night sky. These ornate spheres contain hundreds of thousands of stars, and reside in the outskirts of galaxies. The Milky Way contains over 150 such clusters — and the one shown in this NASA/ESA […]

NASA GRAIL Mission Provides Insights into Moon Impacts

New Research on Lunar Impacts

Astronomers are using data from NASA’s Gravity Recovery and Interior Laboratory mission to provide new insights into the huge impacts that dominated the early history of Earth’s moon and other solid worlds, like Earth, Mars, and the satellites of the outer solar system. In two papers, published this week in the journal Science, researchers examine […]

Astronomers Discover a Young Triple Protostar System

A Triple Protostar System

A team of astronomers has seen a dusty disk of material around a young star fragmenting into a multiple-star system for the first time. Observations with the Atacama Large Millimeter/submillimeter Array and the Karl G. Jansky Very Large Array revealed the process in action. “This new work directly supports the conclusion that there are two […]

A Promising New Form of Immunotherapy for Cancer

New Approach to Cancer Treatment

New research suggests a way to increase the staying power of CAR T cells, a promising form of immunotherapy for cancer. In people with chronic infections or cancer, disease-fighting T cells tend to behave like an overworked militia — wheezing, ill-prepared, tentative, in a state of “exhaustion” that allows disease to persist. In a paper […]

Hubble Sees the Eerie Glow of a Dead Star

New Hubble Image of the Crab Nebula

This newly released Hubble image of the Crab Nebula shows the eerie glow of a dead star, which exploded long ago as a supernova. But don’t be fooled; this ghoulish-looking object still has a pulse. Buried at its center is the star’s tell-tale heart, which beats with rhythmic precision. The “heart” is the crushed core […]

Yale Develops New Gene Editing Strategy to Correct Mutations

New Gene Editing Strategy to Correct Mutations

Using a new gene editing strategy, researchers from Yale University can correct mutations that cause thalassemia, a form of anemia. Their gene editing technique provided corrections to the mutations and alleviated the disease in mice, the researchers said. The finding could lead to studies of a similar gene therapy to treat people with inherited blood […]

Astronomers Find Unexpected Giant Glowing Halos around Distant Quasars

Unexpected Giant Glowing Halos around Distant Quasars Discovered

A new survey by the MUSE instrument on ESO’s Very Large Telescope indicates that halos around quasars are far more common than expected. The properties of the halos in this surprising find are also in striking disagreement with currently accepted theories of galaxy formation in the early Universe. An international collaboration of astronomers, led by […]

Harvard Engineers Create the First Fully 3D-Printed Heart-on-a-Chip

The First 3D-Printed Heart on a Chip

Engineers from Harvard University have made the first entirely 3D-printed organ-on-a-chip with integrated sensing. Using a fully automated, digital manufacturing procedure, the 3D-printed heart-on-a-chip can be quickly fabricated and customized, allowing researchers to easily collect reliable data for short-term and long-term studies. This new approach to manufacturing may one day allow researchers to rapidly design […]

Scientists Generate the Fastest Electric Current Ever Measured Inside a Solid Material

Scientists Generate the Fastest Electric Current to Date Inside a Solid Material

Using ultrafast laser flashes, physicists from the Max Planck Institute have generated the fastest electric current that has ever been measured inside a solid material. In the field of electronics, the principle ‘the smaller, the better’ applies. Some building blocks of computers or mobile phones, however, have become nearly as small today as only a […]

10 Years of Revolutionary Solar Views from NASA’s STEREO Mission

STEREO 10 Years of Revolutionary Solar Views

Ten years ago the twin STEREO spacecraft joined a fleet of NASA spacecraft monitoring the sun and its influence on Earth and space – and they provided a new and unique perspective. Launched 10 years ago, on October 25, 2006, the twin spacecraft of NASA’s STEREO mission – short for Solar and Terrestrial Relations Observatory […]

Astronomers Discover Potential New Hunting Ground for Exoplanets

NASA, Citizen Scientists Discover Potential New Hunting Ground for Exoplanets

A group of citizen scientists and professional astronomers have discovered a star surrounded by the oldest known circumstellar disk — a primordial ring of gas and dust that orbits around a young star and from which planets can form as the material collides and aggregates. Led by Steven Silverberg of University of Oklahoma, the team […]

Two-Pronged Immune Response Destroys Tumors

New Treatment Elicits Two-Pronged Immune Response That Destroys Tumors in Mice

Using a combination of four different therapies, researchers from MIT reveal a new treatment that destroys tumors in mice. Harnessing the body’s own immune system to destroy tumors is a tantalizing prospect that has yet to realize its full potential. However, a new advance from MIT may bring this strategy, known as cancer immunotherapy, closer […]

Cassini Views Saturn’s Dynamic Atmosphere

Astronomers Study Saturn's Fluid Dynamics

Astronomers are using Saturn’s clouds to study fluid dynamics, which seeks to understand the motion of gases and liquids. Saturn’s lack of a solid planetary surface (as on Earth, Mars or Venus) means that its atmosphere is free to flow around the planet essentially without obstruction. This is one factor that generates Saturn’s pattern of […]

Hubble Image of the Red Spider Nebula

This newly released Hubble image shows the Red Spider Nebula, which is located some 3,000 light-years away in the constellation of Sagittarius. Huge waves are sculpted in this two-lobed nebula called the Red Spider Nebula. This warm planetary nebula harbors one of the hottest stars known and its powerful stellar winds generate waves 100 billion […]

Astronomers Reveal That Uranus May Have Two Undiscovered Moons

New Study Suggests Uranus May Have Two Undiscovered Moons

New research suggests that there could be two previously undiscovered moonlets orbiting near Uranus’ rings. Rob Chancia, a University of Idaho doctoral student, spotted key patterns in the rings while examining decades-old images of Uranus’ icy rings taken by Voyager 2 in 1986. He noticed the amount of ring material on the edge of the […]

Neuroscientists Identify Two Key Groups of Neurons That Help Regulate Appetite

Scientists Identify Two Key Groups of Neurons That Help Regulate Appetite

In a newly published study, Scientists from MIT have identify two key groups of neurons within the hypothalamus that help regulate appetite. MIT neuroscientists have discovered that brain cells called glial cells play a critical role in controlling appetite and feeding behavior. In a study of mice, the researchers found that activating these cells stimulates […]
