Possibly the Fastest Moving Pulsar Ever Detected – Traveling at Roughly 6 Million MPH

IGR J11014-6103

Using three different telescopes, scientists found evidence of a pulsar moving at a speed between 5.4 million and 6.5 million miles per hour at a distance of about 30,000 light years away from Earth in the constellation Carina. The evidence for this potentially record-breaking speed comes, in part, from the features highlighted in this composite […]

Ash Preserved Fossils of Rangeomorphs Discovered in Newfoundland

Juvenile example of the rangeomorph fossil Charnia

Found in rocks at the Mistaken Point Ecological Reserve, researchers discovered over 100 fossils of what are believed to be “baby” rangeomorphs that lived 580-550 million years ago. A volcanic eruption around 579 million years ago buried a “nursery” of the earliest-known animals under a Pompeii-like deluge of ash, preserving them as fossils in rocks […]

Immune Response to Heart Attack Can Worsen Atherosclerosis

Heart attack worsens atherosclerosis

A new study explains possible reasons why heart attack patients are at an increased risk for a second heart attack or a stroke, finding that the immune response to the infarct can accelerate the underlying disease by actually increasing the size and inflammation of the atherosclerotic plaque. A heart attack doesn’t just damage heart muscle […]

Spray Paint Battery Can be Painted on Virtually Any Surface

Paintable battery concept

By using spray-painted layers, each representing the components in a traditional battery, researchers at Rice University have developed lithium-ion batteries with consistent capacities that can be painted on almost any surface. Researchers at Rice University have developed a lithium-ion battery that can be painted on virtually any surface. The rechargeable battery created in the lab […]

Near Miss Asteroid – An Opportunity to Test a Rapid Response Program

What to do in the event of an asteroid streaking toward Earth

As an international team of astronomers continues to monitor the skies for approaching asteroids, the recent approach of a 23 foot wide asteroid gave scientists an opportunity to test a rapid-response program. On May 29, an asteroid the size of a bus came whizzing past Earth at 10 times the speed of a fired bullet. […]

A Vapor of Stars from Galaxy DDO 82

DDO 82, also known by the designation UGC 5692

A new image made up of exposures taken in visible and infrared light by Hubble’s Advanced Camera for Surveys shows galaxy DDO 82, which is found in the constellation of Ursa Major approximately 13 million light-years away. Relatively few galaxies possess the sweeping, luminous spiral arms or brightly glowing center of our home galaxy the […]

Cassini Data Reveals Likely Subsurface Ocean on Titan

possible scenario for the internal structure of Titan

By using data from NASA’s Cassini spacecraft to measure variations in the gravitational pull of Titan, researchers were able to determine Titan’s internal structure, finding that Titan likely harbors a layer of liquid water under its ice shell. PASADENA, California — Data from NASA’s Cassini spacecraft have revealed Saturn’s moon Titan likely harbors a layer […]

New Planet Weighing Technique Measures Non-Transiting Planet’s Mass

A New Planet-weighing Technique Found

Using a new method that involves studying the carbon monoxide signature of a planet’s atmosphere, scientists were able to measure the exact mass of a non-transiting planet for the first time. Washington, D.C. — Although there have been about 800 extra-solar planets discovered so far in our galaxy, the precise masses of the majority of […]

A Low-Glycemic Diet is More Effective at Burning Calories

When a calorie is not just a calorie

A new study from Boston Children’s Hospital found that all calories are not created equal, suggesting that a low-glycemic load diet is more effective than conventional approaches at burning calories (and keeping energy expenditure) at a higher rate after weight loss. Published Tuesday in the Journal of the American Medical Association (JAMA), the study challenges […]

Extinctions Due to Habitat Loss are Proportional to the Area Destroyed

Extinction threat due to habitat loss greater than believed

While studying extinction threat due to habitat loss, scientists found that the relationship between geographic area and richness of species primarily depends on the mean size of species’ geographic ranges. As human encroachment continues to shrink the habitable area for other animal species, a new study suggests that associated extinctions may be more severe than […]

Using Chitosan to Remove Arsenic from Water Supplies

chitosan beads impregnated with titanium dioxide and aluminum oxide remove heavy metals

By turning chitosan into beads and impregnating them with nanoparticles of titanium dioxide and aluminum oxide, scientists developed a technique that removes both arsenite and arsenate with the same efficacy as the nanopowders, but without the post-treatment filtration requirements. Inorganic arsenic, which can contaminate water supplies via runoff from industrial manufacturing and mining processes, is […]

Searching for Molecular Oxygen in the Orion Nebula

Hubble image of a region of the Orion Nebula

Using the Herschel Space Observatory, CfA astronomers led a team in search of molecular oxygen in the Orion Nebula, reporting that they still did not find O2, but reached preliminary conclusions about several issues. Searches for interstellar molecular oxygen, O2, have a long history, and the motivation for these searches has evolved. Prior to the […]

NASA Data Reveals Significant Changes in Exoplanet’s Atmosphere

rendering illustrates the evaporation of HD 189733b's atmosphere

Similar to Jupiter, exoplanet HD 189733b is a gas giant that circles its star, named HD 189733A, at a distance of only 3 million miles and completes an orbit every 2.2 days. Using Hubble, scientists were able to show that at least 1,000 tons of hydrogen gas was escaping from the planet’s upper atmosphere every […]
