NASA’s Chandra Views Supernova Remnant G299

Chandra Views Supernova Remnant G299

This new image from NASA’s Chandra X-ray Observatory shows supernova remnant G299.2-2.9. Because the debris fields of exploded stars, known as supernova remnants, are very hot, energetic, and glow brightly in X-ray light, NASA’s Chandra X-ray Observatory has proven to be a valuable tool in studying them. The supernova remnant called G299.2-2.9 (or G299 for […]

Astronomers View the Formation of a Quadruple Star System

The Formation of a Quadruple Star System

A newly published study details the discovery of a wide-separation quadruple system composed of a young protostar and three gravitationally bound dense gas condensations. Amherst, Massachusetts – This week an international team of astronomers reports the first multiple-star system to be observed during the earliest stage of formation. This finding supports model predictions about how […]

Inkjet-Printing System Could Enable Mass-Production of Large-Screen OLED Displays

Inkjet-Printing System Could Enable Mass-Production of OLED Displays

Based on years of Institute research, MIT spinout Kateeva has developed an “inkjet printing” system that could cut manufacturing costs enough to pave the way for mass-producing flexible and large-screen OLED displays. Flexible smartphones and color-saturated television displays were some highlights at this year’s Consumer Electronics Showcase, held in January in Las Vegas. Many of […]

Nano-Antioxidants Quickly Neutralize Superoxides

Study Shows How Particles Quench Damaging Superoxides

A new Rice-led study reveals how nanoparticles can quickly neutralize superoxides that are overexpressed by the body’s cells in response to an injury. Injectable nanoparticles that could protect an injured person from further damage due to oxidative stress have proven to be astoundingly effective in tests to study their mechanism. Scientists at Rice University, Baylor […]

Study Reveals Oceanic Carbon Release Helped End the Ice Age

Carbon Release from Ocean Helped End the Ice Age

New research shows that high concentrations of dissolved carbon dioxide in ocean water coincides with rises in atmospheric carbon dioxide and global temperatures at the end of the last ice age, giving scientists valuable insights into how the ocean can affect the carbon cycle and climate change. New techniques are allowing scientists to understand how […]

Astronomers Discover a New Class of Binary Stars

Astronomers Identify 18 Extreme Mass-Ratio Binary Stars

Astronomers from the Harvard-Smithsonian Center for Astrophysics have discovered a new class of binary stars; one star is fully formed while the other is still in its infancy. Cambridge, Massachusetts – The majority of stars in our galaxy come in pairs. In particular, the most massive stars usually have a companion. These fraternal twins tend […]

VLA Reveals Unexpected “Storm” in Teacup Galaxy

VLA Finds Storm in Teacup Galaxy

Astronomers used VLA data, combined with VIMOS IFU data and HST imaging to reveal that a supermassive black hole is explosively heating and blasting around the gas the Teacup Galaxy, transforming it from an actively star-forming galaxy into one devoid of gas that can no longer form stars. Astronomers using the National Science Foundation’s Very […]

Barb Geometry of Asymmetrical Feathers Sheds Light on Evolution of Flight

Feathers Shed Light on Evolution of Flight

By taking a closer look at feathers representing the evolutionary transition from dinosaurs to modern birds, Yale researchers demonstrate a better understand of how feathers facilitate flight in modern birds. The asymmetrical flight feathers of their wings are among the most distinctive features of living birds. But how are these feathers actually constructed, and when […]

A Closer Look at the Icy Conditions of Comets

Study-Helps-Explain-Comet-Composition

New research from NASA’s Jet Propulsion Laboratory used a cryostat instrument, nicknamed “Himalaya,” to study the icy conditions under which comets form. Astronomers tinkering with ice and organics in the lab may have discovered why comets are encased in a hard, outer crust. Using an icebox-like instrument nicknamed Himalaya, the researchers show that fluffy ice […]

Evidence for the Presence of Dark Matter in the Innermost Part of the Milky Way

Researchers Find Evidence for Dark Matter in the Inner Milky Way

A new study from astrophysicists at Stockholm University provides evidence for the presence of dark matter in the innermost part of the Milky Way, including in our own cosmic neighborhood and the Earth’s location. The study demonstrates that large amounts of dark matter exist around us, and also between us and the Galactic center. The […]

Engineered Insulin Stays in Bloodstream, Offers Better Diabetes Control

Engineered Insulin Offers Better Diabetes Control

Engineers from MIT have developed insulin that can circulate in the bloodstream for hours, responding rapidly to changes in blood-sugar levels. For patients with diabetes, insulin is critical to maintaining good health and normal blood-sugar levels. However, it’s not an ideal solution because it can be difficult for patients to determine exactly how much insulin […]
