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 […]

Solar Dynamics Observatory Spots Giant Filament on the Sun

SDO Views Giant Filament on the Sun

This new image from NASA’s Solar Dynamics Observatory shows a giant filament on the Sun. A dark line snaked across the lower half of the sun on February 10, 2015, as seen in this image from NASA’s Solar Dynamics Observatory, or SDO. SDO shows colder material as dark and hotter material as light, so the […]

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 […]

Geologists Reveal Earth’s Inner Core Has an Inner Core of Its Own

Geologists Unlock Mysteries of Earth's Inner Core

New research from a team of geologists reveals that the Earth’s inner core has an inner core of its own, with crystals aligned in a different direction. Champaign, Illinois — Seismic waves are helping scientists to plumb the world’s deepest mystery: the planet’s inner core. Thanks to a novel application of earthquake-reading technology, a research […]

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 […]

Orbital Engineering, Yale Engineers Change Electron Trajectories

Engineers Change Electron Trajectories

In a newly published study, engineers demonstrate a novel approach to substantially modify orbital occupations and symmetries in electronically correlated oxides. How do you make nickel look and behave like copper? A team of scientists at Yale University has done just that by developing a novel technique to artificially alter a material’s atomic properties by […]

NASA’s Mars Reconnaissance Orbiter Completes 40,000 Mars Orbits

Mars Reconnaissance Orbiter Completes 40,000 Mars Orbits

Launched in 2005, the Mars Reconnaissance Orbiter has now orbited the Red Planet more than 40,000 times. NASA’s Mars Reconnaissance Orbiter passed a mission milestone of 40,000 orbits on February 7, 2015, in its ninth year of returning information about the atmosphere, surface and subsurface of Mars, from equatorial to polar latitudes. The mission’s potent […]

3D Vaccine Spontaneously Assembles to Fight Cancer, Infectious Diseases

3D Vaccine Delays Tumor Growth in Mice

Researchers have developed a new 3D vaccine that spontaneously assembles to provide a more effective way to harness the immune system to fight cancer as well as infectious diseases. The vaccine spontaneously assembles into a scaffold once injected under the skin and is capable of recruiting, housing, and manipulating immune cells to generate a powerful […]

Scientists Discover the Greatest Absence of Evolution Ever Reported

Scientists Discover Organism That Hasn’t Evolved

Scientists from UCLA have discovered an organism that hasn’t evolved in more than 2 billion years. An international team of scientists has discovered the greatest absence of evolution ever reported — a type of deep-sea microorganism that appears not to have evolved over more than 2 billion years. But the researchers say that the organisms’ […]

Energy Drinks Significantly Increase Hyperactivity and Inattention in Children

Study Shows Energy Drinks Significantly Increase Hyperactivity in Schoolchildren

New research from Yale University shows that middle-school children who consume heavily sweetened energy drinks are 66% more likely to be at risk for hyperactivity and inattention symptoms. The finding has implications for school success and lends support to existing recommendations to limit the amount of sweetened beverages schoolchildren drink. The authors also recommend that […]

Ultrasound Can Detect Cancers Missed by Mammography

Untapped Potential for Supplementing Mammography

New research shows that a supplementary screening with ultrasound can detect cancers missed by mammography, and reveals that women with dense breast tissue can benefit from this extra screening. The purpose of screening examinations for breast cancer is to detect tumors before they cause symptoms such as a lump, swelling or redness. Discovering tumors in […]

Astronomers Measure the Rotation Periods of Thirty Sun-Like Stars

Astronomers Measure the Rotation Periods of Sun-Like Stars

Using the precise data from the Kepler exoplanet mission, astronomers from the Harvard-Smithsonian Center for Astrophysics have determined the rotation period measurements for 30 cool stars in the 2.5- billion-year-old stellar cluster NGC 6819. The mass of a star is perhaps its most significant feature. It determines how brightly it shines (a star ten times […]

New Insight Into HIV Vaccination Strategies

New Research Yields Insight Into Generating Antibodies That Target Different Strains of HIV

New research yields insight into generating antibodies that target different strains of HIV, suggesting that sequentially administering several different forms of a potential HIV vaccine could stimulate a stronger immune response than delivering a cocktail of these variants all at once. Through an investigation of a fundamental process that guides the maturation of immune cells, […]
