First ab initio method for characterizing hot carriers

July 18, 2014 8:19 am | by Lynn Yarris, Lawrence Berkeley National Laboratory | News | Comments

One of the major road blocks to the design and development of new, more efficient solar cells may have been cleared. Researchers with the Lawrence Berkeley National Laboratory have developed the first ab initio method for characterizing the properties of “hot carriers” in semiconductors. Hot carriers are electrical charge carriers with significantly higher energy than charge carriers at thermal equilibrium.

Future electronics may depend on lasers, not quartz

July 18, 2014 8:09 am | by Jessica Stoller-Conrad, Caltech | News | Comments

Nearly all electronics require devices called oscillators that create precise frequencies. For nearly 100 years, these oscillators have relied upon quartz crystals to provide a frequency reference, much like a tuning fork is used as a reference to tune a piano. However, future high-end navigation systems, radar systems and even possibly tomorrow's consumer electronics will require references beyond the performance of quartz.

Nanocamera takes pictures at distances smaller than light’s wavelength

July 18, 2014 7:55 am | by Rick Kubetz, Engineering Communications Office | Videos | Comments

Researchers at the Univ. of Illinois at Urbana-Champaign have demonstrated that an array of novel gold, pillar-bowtie nanoantennas (pBNAs) can be used like traditional photographic film to record light for distances that are much smaller than the wavelength of light (for example, distances less than ~600 nm for red light). A standard optical microscope acts as a “nanocamera” whereas the pBNAs are the analogous film.

July 18, 2014 7:40 am | by Jennifer Chu, MIT News Office | Videos | Comments

Twisting a screwdriver, removing a bottle cap and peeling a banana are just a few simple tasks that are tricky to pull off single handedly. Now a new wrist-mounted robot can provide a helping hand—or rather, fingers. Researchers at Massachusetts Institute of Technology have developed a robot that enhances the grasping motion of the human hand.

Why airlines didn't avoid risky Ukraine airspace

July 18, 2014 3:22 am | by David Koenig - AP Airlines Writers - Associated Press | News | Comments

The possibility that the civilian jetliner downed over war-torn eastern Ukraine with nearly 300 people onboard was hit by a missile could have profound consequences for the world's airlines. Airlines might have to be more vigilant about avoiding trouble spots, making flights longer and causing them to burn more costly fuel. They may even be forced to reconsider many international routes.

National Xenopus Resource at MBL innovates new way to study proteins

July 17, 2014 10:45 am | by Laurel Hamers, Marine Biological Laboratory | News | Comments

Many organisms that hold potential for proteomic analysis do not yet have a completely sequenced genome because the costs are prohibitive. Xenopus laevis, the African clawed frog, is one such species. Researchers at the Marine Biological Laboratory have found a work-around. Instead of relying on DNA, they used mRNA sequences to more efficiently create a reference database that can be used for proteomic analysis of Xenopus.

Making a mental match: Pairing a mechanical device with stroke patients

July 17, 2014 9:36 am | by Jason Maderer, Georgia Institute of Technology | Videos | Comments

The repetitive facilitation exercise is one of the most common rehabilitation tactics for stroke patients attempting to regain wrist movement. Stroke hemiparesis individuals are not able to move that part of their body because they cannot create a strong enough neural signal that travels from the brain to the wrist.

Toward ultimate light efficiency on the cheap

July 17, 2014 9:27 am | by Kate McAlpine, Univ. of Michigan | News | Comments

Researchers have taken a major stride toward perfectly efficient lighting that is also relatively inexpensive and simple to make. The same material can also reveal the presence of water by changing color. Incandescent bulbs only turn 5% of the electricity they use into light, while fluorescent LEDs can produce light from up to 25% of the electrons that pass through them. Phosphorescent LEDs can turn every electron into a ray of light.

After hybrid success, Toyota gambles on fuel cell

Cell membrane proteins give up their secrets

July 17, 2014 8:03 am | Videos | Comments

Biological physicists at Rice Univ. have succeeded in analyzing transmembrane protein folding in the same way they study the proteins’ free-floating, globular cousins. They have applied energy landscape theory to proteins that are hard to view because they are inside cell membranes. The method should increase the technique’s value to researchers who study proteins implicated in diseases and possibly in the creation of drugs to treat them.

No-wait data centers

July 17, 2014 7:56 am | by Larry Hardesty, MIT News Office | News | Comments

Big Websites usually maintain their own “data centers,” banks of tens or even hundreds of thousands of servers, all passing data back and forth to field users’ requests. Like any big, decentralized network, data centers are prone to congestion: Packets of data arriving at the same router at the same time are put in a queue, and if the queues get too long, packets can be delayed.

Water molecules favor negative charges

July 17, 2014 7:52 am | News | Comments

Recent research shows that, in the presence of charged substances, water molecules favor associating with elements with a negative electrical charge rather than a positive electric charge. A study on the subject that employed advanced optical spectroscopy techniques could provide new insights on the processes of cell formation.
