Yale Scientists Reveal Ebola Epidemic in Africa Poised to Explode

Yale Study Shows Ebola Epidemic in Africa Poised to Explode

An international team of scientists has developed a new mathematical transmission model of the Ebola disease and applied it to Liberia’s most populous county, revealing that tens of thousands of new Ebola cases and deaths are likely by December 15 if the epidemic continues on its present course. The Ebola virus disease epidemic already devastating […]

New TLP Coating Repels Blood and Bacteria

New Coating for Medical Devices Repels Blood and Bacteria

Using materials already approved by the FDA, Harvard engineers have developed a new surface coating for medical devices that repels blood and suppresses biofilm formation. Most any medical device implanted in the body — or one that comes into contact with flowing blood, such as a dialysis machine — may also present two critical challenges […]

Hubble Views Comet Siding Spring Passing Mars

Hubble Views Comet Siding Spring Near Mars

This new composite image of comet Siding Spring was captured by NASA’s Hubble Space Telescope as Sliding Spring made its never-before-seen close passage of Mars. Siding Spring, officially designated Comet C/2013 A1, made its closest approach to Mars at 2:28 p.m. EDT on October 19, at a distance of approximately 87,000 miles. That is about […]

New Evidence of a Possible Link Between Diabetes and the Hardening of Heart Valves

Study Shows High Blood Sugar Levels May Harden Heart Valves

By directly viewing the effect of high blood-sugar levels on heart-valve cell metabolism for the first time, bioengineers have found new evidence of a possible link between diabetes and the hardening of heart valves. Rice University bioengineers have found new evidence of a possible link between diabetes and the hardening of heart valves. A Rice […]

Research Shows Ancient Kangaroos Likely Preferred Walking to Hopping

Ancient Family of Sthenurine Kangaroos Likely Preferred Walking to Hopping

Based on a rigorous comparative analysis of kangaroo anatomy, biologists at Brown University reveal that the ancient family of sthenurine kangaroos likely preferred walking to hopping. Imagine that a time machine has transported you to the Australian outback 100,000 years ago. As you emerge, you see a huge kangaroo with a round rabbit-like face foraging […]

New Target Finding Mechanism Allows Microscopic Devices to Autonomously Find Their Way

New Technology Allows Microscopic Devices to Autonomously Find Their Way

Researchers from MIT have developed a new target-finding mechanism that allows microscopic devices to autonomously find their way to areas of a cell surface. Nature has developed a wide variety of methods for guiding particular cells, enzymes, and molecules to specific structures inside the body: White blood cells can find their way to the site […]

Chandra X-ray Observatory Image of PSR B1509-58: Illusions in the Cosmic Clouds

Chandra Xray Observatory Image Illusions in the Cosmic Clouds

First released in 2009, this Chandra image shows PSR B1509-58 – a spinning neutron star surrounded by a cloud of energetic particles. Pareidolia is the psychological phenomenon where people see recognizable shapes in clouds, rock formations, or otherwise unrelated objects or data. There are many examples of this phenomenon on Earth and in space. When […]

Ultra-Black Nano-Coating Applied to New 3D Solar Coronagraph

New Super Black Carbon Nanotube Coating for 3D Solar Coronagraph

NASA scientists have applied new super-black carbon-nanotube coating to a 3-D component critical for suppressing stray light in a new solar coronagraph. An emerging super-black nanotechnology that is to be tested for the first time this fall on the International Space Station will be applied to a complex, 3-D component critical for suppressing stray light […]

New Spitzer Image: Galactic Wheel of Life Shines in Infrared

Spitzer Views Galaxy NGC 1291

A newly released image from the Spitzer Space Telescope shows galaxy NGC 1291, which is located about 33 million light-years away in the constellation Eridanus. It might look like a spoked wheel or even a “Chakram” weapon wielded by warriors like “Xena,” from the fictional TV show, but this ringed galaxy is actually a vast […]

A New Self-Assembly Method for Fabricating Graphene Nanoribbons

New Method for Fabricating Graphene Nanoribbons Brings Scientists Closer to Revolutionizing Electronics

Scientists from UCLA and Tohoku University have discovered a new self-assembly method for producing defect-free graphene nanoribbons, bringing them one step closer to revolutionizing electronics. First characterized in 2004, graphene is a two-dimensional material with extraordinary properties. The thickness of just one carbon atom, and hundreds of times faster at conducting heat and charge than […]

Small-Scale Jets from the Solar Chromosphere Are Possible Sources of the Solar Wind

Astronomers Detect Sources of the Solar Wind

In a newly published study, astronomers from the Harvard-Smithsonian Center for Astrophysics reveal the detection of intermittent, small-scale jets from the solar chromosphere and their possible contribution to the stellar wind. The solar chromosphere is the region between the Sun’s surface and its hot, million-degree corona. Within this complex interface zone, only a few thousand […]
