One step closer to nanobiorobots

August 21, 2014 11:51 pm | News | Comments

This small step towards creating efficient nanobiorobots opens up great vistas for further research, similar to the creation of the first nanobiocomputers and the creation of the first diodes and transistors, which resulted in the rapid development of electronic computers.

Engineers take major step toward photonic circuits

August 21, 2014 11:42 pm | News | Comments

Electrical engineering researchers at UAlberta are designing nano-optical cables small enough to replace the copper wiring on computer chips. This could result in radical increases in computing speeds and reduced energy use by electronic devices.


Solar energy that doesn't block the view

August 21, 2014 11:28 pm | News | Comments

Past efforts in the production of energy from solar cells have yielded poor results; the energy production was inefficient and the materials were highly-colored. MSU researchers have developed a new type of solar concentrator that when placed over a window creates solar energy while allowing people to actually see through the window.


NASA's RXTE satellite decodes the rhythm of an unusual black hole

August 21, 2014 12:09 am | News | Comments

Astronomers have uncovered rhythmic pulsations from a rare type of black hole 12 million light-years away by sifting through archival data from NASA's Rossi X-ray Timing Explorer (RXTE) satellite. By going over past RXTE observations, the astronomers found specific changes in brightness that helped them determine M82 X-1 measures around 400 solar masses.

Raytheon and UMass Lowell establish joint research facility for advanced materials

August 20, 2014 11:45 pm | News | Comments

Initial research will focus on future technologies for radar and communication systems. The institute will leverage UMass Lowell’s strengths in printed electronics and nanotechnology that align with Raytheon’s strategic technology needs including high-frequency printed conformal antennas, carbon-based transistors and photonic devices.


Sun Pharma unit recalls cephalexin capsules from US

August 20, 2014 4:47 pm | News | Comments

Citing a notification by the USFDA, the report says that the recall of the 3,40,553 units of 500 mg and 1,13,677 units of 250 mg bottles is voluntarily initiated by the company through a letter to the regulator in June under 'Class-II' classification.  


Promising ferroelectric materials reveal quirky habit

August 20, 2014 3:26 pm | News | Comments

Electronic devices with unprecedented efficiency and data storage may someday run on ferroelectrics—materials that use built-in electric polarizations to read and write digital information, outperforming the magnets inside most popular data-driven technology. But ferroelectrics must first overcome a few key stumbling blocks, including a curious habit of "forgetting" stored data.


Graphene rubber bands could stretch limits of healthcare

August 19, 2014 9:11 pm | News | Comments

Although body motion sensors already exist in different forms, they have not been widely used due to their complexity and cost of production. Researchers have for the first time treated common elastic bands with graphene, to create a flexible sensor that is sensitive enough for medical use and can be made cheaply.


Organic photovoltaic cells show promise for energy conversion

August 19, 2014 9:09 pm | News | Comments

 A team of researchers in Japan has developed a method to determine the absolute value of the charge formation efficiency. The secret of their method, as they report in Applied Physics Letters, is the combination of two types of spectroscopy.

Chip makers skip summer break to meet smartphone demand

August 19, 2014 8:19 pm | News | Comments

While much of Japan relaxed during the Bon summer holiday period, its top semiconductor makers kept their factories running to meet fierce demand from China for the technology that runs smartphones. Demand is expected to heat up even more next month.


NASA tests green fuel in orbit

August 19, 2014 11:38 am | News | Comments

Milestone progress is being made in readying NASA’s Green Propellant Infusion Mission (GPIM) for launch in 2016, a smallsat designed to test the unique attributes of a high-performance, non-toxic, “green” fuel on orbit. The GPIM marks the first time the U.S. will use a spacecraft to test green propellant technology. 


FDA warns about fraudulent Ebola treatment products

August 18, 2014 11:56 pm | News | Comments

The U.S. FDA is advising consumers to be aware of products sold online claiming to prevent or treat the Ebola virus. Since the outbreak of the Ebola virus in West Africa, the FDA has seen and received consumer complaints about a variety of products claiming to either prevent the Ebola virus or treat the infection.

European nutraceuticals market expected to reach $845.84M

August 18, 2014 12:36 pm | News | Comments

The nutraceuticals market in Europe is estimated to grow from around $558.55 million in 2012 to $845.84 million by 2018, at a CAGR of 7.2%, from 2013 to 2018. Consumer willingness to spend premium amounts on quality nutraceuticals has further caused a spur in the demand for mineral ingredients.


Seven tiny grains captured by Stardust likely visitors from interstellar space

August 18, 2014 12:27 am | News | Comments

Since 2006, when NASA’s Stardust spacecraft delivered its aerogel and aluminum foil dust collectors back to Earth, a team of scientists has combed through the collectors in search of rare, microscopic particles of interstellar dust. The team now reports that they have found seven dust motes that probably came from outside our solar system, perhaps created in a supernova explosion millions of years ago and altered by eons. 

Chemists uncover powerful click chemistry reactivity

August 18, 2014 12:13 am | News | Comments

The findings open a doorway on an unexplored chemical galaxy containing vast numbers of new molecules for making drugs, plastics and unprecedented smart materials. The new SuFEx reactions enable chemists to link molecules of their choice together using derivatives of a common commercial chemical considered essentially inert.
