Tuberculosis: Daily antibiotics recommended to prevent resistant strains

November 24, 2015 10:00 am | by Kate McAlpine, Univ. of Michigan | News | Comments

A computer model of tuberculosis has shown that approved treatments prescribing antibiotic doses once or twice a week are more likely to lead to drug resistant strains than are daily antibiotic regimens. The finding, from a Univ. of Michigan study, could help inform the treatment of the roughly 10 million people worldwide who fall ill with tuberculosis each year.


Hairy Dark Matter

November 24, 2015 9:41 am | by Greg Watry, Digital Reporter | Articles | Comments

If dark matter were visible, the Earth would be in need of a haircut. A researcher from NASA’s Jet Propulsion Laboratory (JPL) published a new study in the Astrophysical Journal proposing the existence of long filaments of dark matter, or hairs, near planetary bodies.


Chemical design made easier

November 24, 2015 7:44 am | by Mike Williams, Rice Univ. | News | Comments

Rice Univ. scientists using an efficient metal-free process have synthesized dozens of small-molecule catalysts, tools that promise to speed the making of novel chemicals, including drugs. The lab of synthetic chemist László Kürti made elusive chiral biaryl compounds in a single-flask process that does not require the use of transition metals.


A new way to make x-rays

November 24, 2015 7:35 am | by David L. Chandler, MIT News Office | News | Comments

The most widely used technology for producing x-rays has remained essentially the same for more than a century. But based on a new analysis by researchers at Massachusetts Institute of Technology, that might potentially change in the next few years.


Supercomputer simulations enhance understanding of protein motion, function

November 24, 2015 7:27 am | by Morgan McCorkle, Oak Ridge National Laboratory | News | Comments

Supercomputing simulations at Oak Ridge National Laboratory could change how researchers understand the internal motions of proteins that play functional, structural and regulatory roles in all living organisms.


An eagle-eye, real-time view of neural activity

November 24, 2015 7:20 am | by Ken Kingery, Duke Univ. | News | Comments

Researchers at Duke and Stanford Univs. have devised a way to watch the details of neurons at work, pretty much in real time. Every second of every day, the 100 billion neurons in your brain are capable of firing off a burst of electricity called an action potential up to 100 times per second.


NOAA Global Warming Study Under Fire

November 23, 2015 4:07 pm | by Greg Watry, Digital Reporter | Articles | Comments

Following criticism from the chairman of the House of Representative’s Committee on Science, Space, and Technology regarding a global warming study published in Science in June, a spokeswoman from the publication recently said the journal did not rush to publish the National Oceanic and Atmospheric Administration (NOAA) study.


The Garden Rose: Marrying the Electronic and Organic

November 23, 2015 4:04 pm | by Greg Watry, Digital Reporter | Articles | Comments

The garden rose, or Rosa floribunda, has ingrained itself into public consciousness as the symbol for love. But in the science world, the rose is now the first plant to marry the electronic and organic within its body. Researchers from Linköping Univ.’s Laboratory of Organic Electronics used the rose’s vascular system to manufacture analog and digital organic electronic circuits and devices.


Martian Moon’s Demise May Create Planetary Ring

November 23, 2015 1:01 pm | by Greg Watry, Digital Reporter | Articles | Comments

The death throes of a moon may signal the birth of something else. Remember Phobos? The Martian moon being ripped apart by tidal forces. Well, it turns out that 20 to 40 million years from now, the disintegrating moon may add a new feature to Mars’ aesthetic: a ring system.


Tandem solar cells are simply better

November 23, 2015 12:00 pm | by Swiss Federal Laboratories for Materials Science and Technology (EMPA) | News | Comments

What's true for double-blade razors is also true for solar cells: two work steps are more thorough than one. Stacking two solar cells one on top of the other, where top cell is semi-transparent, which efficiently converts large energy photons into electricity, while the bottom cell converts the remaining or transmitted low energy photons in an optimum manner. This allows a larger portion of the light energy to be converted to electricity.


Bestowing the World’s Oldest Tattoo Title

November 23, 2015 11:16 am | by Greg Watry, Digital Reporter | Articles | Comments

It was an accidental discovery. In 1991, hikers stumbled upon a mummified corpse in the Ötzal Alps, which straddles the border between Italy and Austria. Naturally preserved by a combination of glacial meltwater and cold weather, Ötzi, the Tyrolean Iceman, boasted 61 tattoo markings across his weathered body.


Nanomagnets: Creating order out of chaos

November 23, 2015 10:49 am | by Helmholtz-Zentrum Dresden-Rossendorf | News | Comments

Miniaturization is the magic word when it comes to nanomagnetic devices intended for use in new types of electronic components. Scientists  have proposed the use of ion beams for their fabrication. An ultra-fine beam consisting of around 10 neon ions suffices to bring several hundred atoms of an iron-aluminum alloy into disarray and thereby generate a nanomagnet embedded directly in the material.


Wireless sensor enables study of traumatic brain injury

November 23, 2015 10:37 am | by Emil Venere, Purdue Univ. | News | Comments

A new system that uses a wireless implant has been shown to record for the first time how brain tissue deforms when subjected to the kind of shock that causes blast-induced trauma commonly seen in combat veterans.


The R&D Index Market Pulse, November 23, 2015: High Tax Rates Inspire More Inversions

November 23, 2015 9:45 am | by Tim Studt | Articles | Comments

The R&D Index: Market Pulse for the week ending November 20, 2015, closed at 1,563.85 for the 25 companies in the R&D Index. The R&D Index was up 3.71% (or more than 55 basis points) over the previous week ending November 6, 2015—almost the identical amount that the R&D Index was down the previous week (November 13 from November 6, so zero net change over the past two weeks).


NASA Taps SpaceX to Send Americans to Space

November 23, 2015 9:36 am | by Greg Watry, Digital Reporter | Articles | Comments

NASA called Elon Musk’s SpaceX to the plate recently by giving the company a mission order to send astronauts to space from U.S. soil. “The authority to proceed with (SpaceX Crew Dragon’s) first operational crew missions is a significant milestone in the Commercial Crew Program and a great source of pride for the entire SpaceX team,” said Gwynne Shotwell, SpaceX’s president and chief operating officer.
