Novel nanoparticles could save soldiers’ lives after explosions

April 16, 2015 8:11 am | by American Chemical Society | News | Comments

Soldiers who suffer internal trauma from explosions might one day benefit from a new treatment now under development. Researchers report in ACS Macro Letters that injecting a certain type of nanoparticle helped reduce lung damage in rats experiencing such trauma. The potential treatment, which could be given at the most critical moment immediately after a blast, could save lives.

BPA exposure in pregnant mice affects fertility in three generations

April 16, 2015 8:03 am | by Diana Yates, Life Sciences Editor, Univ. of Illinois | News | Comments

When scientists exposed pregnant mice to levels of bisphenol A (BPA) equivalent to those considered safe in humans, three generations of female mouse offspring experienced significant reproductive problems, including declines in fertility, sexual maturity and pregnancy success, the scientists report in Toxicology and Applied Pharmacology.

Cobalt film a clean-fuel find

April 16, 2015 7:51 am | by Mike Williams, Rice Univ. | News | Comments

A cobalt-based thin film serves double duty as a new catalyst that produces both hydrogen and oxygen from water to feed fuel cells, according to scientists at Rice Univ. The inexpensive, highly porous material may have advantages as a catalyst for the production of hydrogen via water electrolysis. A single film far thinner than a hair can be used as both the anode and cathode in an electrolysis device.

Packing heat: New fluid makes untapped geothermal energy cleaner

April 16, 2015 7:43 am | by Frances White, PNNL | Videos | Comments

More American homes could be powered by the Earth's natural underground heat with a new, nontoxic and potentially recyclable liquid that is expected to use half as much water as other fluids used to tap into otherwise unreachable geothermal hot spots. The fluid might be a boon to a new approach to geothermal power called enhanced geothermal systems.

Discovery changes how scientists examine rarest elements of periodic table

April 16, 2015 7:34 am | by Kathleen Haughney, Florida State Univ. | News | Comments

A little-known element called californium is making big waves in how scientists look at the periodic table. According to new research by a Florida State Univ. professor, californium is what's known to be a transitional element, meaning it links one part of the Periodic Table of Elements to the next.

Study: Many Medicare cataract patients given needless tests

April 15, 2015 6:05 pm | by Marilynn Marchione, AP Chief Medical Writer, Associated Press | News | Comments

Millions of older people are getting tests they don't need to prove they are healthy enough to have cataracts removed, a new study finds. The excess testing before this quick, ultra-safe eye procedure is costing them and Medicare a bundle, and many patients don't know they can question it, doctors say.

Making injections less painful

April 15, 2015 10:45 am | by Mike Williams, Rice Univ. | Videos | Comments

If the Rice Univ. freshman engineering design team Comfortably Numb has it their way, children will be less fearful and feel less pain when they go to the doctor’s office for a shot. The trio of freshmen has created a device to ease the pain of an injection. Their device numbs the skin prior to a shot by producing a rapid chemical reaction to cool the patient’s skin.

A camera that powers itself

April 15, 2015 10:03 am | by Holy Evarts, Columbia Univ. School of Engineering and Applied Science | News | Comments

A Columbia Engineering research team has invented a prototype video camera that is the first to be fully self-powered: It can produce an image each second, indefinitely, of a well-lit indoor scene. They designed a pixel that can not only measure incident light but also convert the incident light into electric power.

Researchers create bio-inspired flame retardants

April 15, 2015 9:53 am | by NIST | News | Comments

After devising several new and promising "green" flame retardants for furniture padding, NIST researchers took a trip to the grocery store and cooked up their best fire-resistant coatings yet. As important, these protective coatings can be made in one straightforward step.

Shape-shifting molecule tricks viruses into mutating themselves to death

April 15, 2015 9:36 am | by Steve Koppes, Univ. of Chicago | News | Comments

A newly developed spectroscopy method is helping to clarify the poorly understood molecular process by which an anti-HIV drug induces lethal mutations in the virus’ genetic material. The findings from the Univ. of Chicago and the Massachusetts Institute of Technology could bolster efforts to develop the next generation of anti-viral treatments.

Nano-coated mesh could clean oil spills

April 15, 2015 9:24 am | by Pam Frost Gorder, Ohio State Univ. | News | Comments

The mesh coating is among a suite of nature-inspired nanotechnologies under development at Ohio State and described in two papers in Nature Scientific Reports. Potential applications range from cleaning oil spills to tracking oil deposits underground.

NMR “fingerprinting” for monoclonal antibodies

April 15, 2015 8:49 am | by NIST | News | Comments

NIST researchers have demonstrated the most precise method yet to measure the structural configuration of monoclonal antibodies, an important factor in determining the safety and efficacy of these biomolecules as medicines. Monoclonal antibodies are proteins manufactured in the laboratory that can target specific disease cells or antigens (proteins that trigger an immune reaction) for removal from the body.

New “cool roof time machine” will accelerate cool roof deployment

April 15, 2015 8:36 am | by Julie Chao, Lawrence Berkeley National Laboratory | News | Comments

Cool roofs can help keep buildings cool, thus lowering the building’s energy use, while also mitigating the urban heat island effect by reflecting sunlight away from buildings and cities. But as cool roofs age and get soiled, how much of their reflectance do they lose?

Spitzer, OGLE spot planet deep within our galaxy

April 15, 2015 7:44 am | by Christine Pulliam, Harvard-Smithsonian Center for Astrophysics | News | Comments

NASA's Spitzer Space Telescope has teamed up with a telescope on the ground to find a remote gas planet about 13,000 light-years away, making it one of the most distant planets known. The discovery demonstrates that Spitzer can be used to help solve the puzzle of how planets are distributed throughout our flat, spiral-shaped Milky Way galaxy. Are they concentrated heavily in its central hub, or more evenly spread throughout its suburbs?
