Researchers record sight neurons in jumping spider brain

October 22, 2014 | Videos | Comments

Though neurobiologists have tried for half a century to better understand the brains of jumping spiders, no one has succeeded. The liquid in spiders’ bodies is pressurized, and they move with hydraulic pressure and muscles. But with a new technique using a tiny tungsten recording electrode, researchers have made recordings of neurons associated with visual perception inside the poppy seed-sized brain the spider.

R&D 100 Award Video: Calcium Loop for Carbon Capture

October 20, 2014 9:07 am | by Lindsay Hock, Managing Editor Videos Comments

Carbon capture and sequestration isn’t only suitable for new power plants, but more essential in retrofitting existing ones. Because of this retrofitting nature, carbon capture and sequestration is regarded by the International Energy Agency as the single technology most capable of carbon dioxide reduction in the world and could account for more than 20% of global carbon dioxide abatement by 2050.

First observations of atoms moving inside bulk material

October 14, 2014 8:23 am | by Christopher R. Samoray, Oak Ridge National Laboratory Videos Comments

Researchers at Oak Ridge National Laboratory have obtained the first direct observations of atomic diffusion inside a bulk material. The research, which could be used to give unprecedented insight into the lifespan and properties of new materials, is published in Physical Review Letters.

DNA’s security system unveiled

October 13, 2014 9:04 am | by Bill Hathaway, Yale Univ. Videos Comments

As befitting life’s blueprint, DNA is surrounded by an elaborate security system that assures crucial information is imparted without error. The security is provided by a double membrane perforated by protein channels that block unwanted material from entering the nucleus and promote entry of key messengers.

Teams set new records for silicon quantum computing

October 13, 2014 8:55 am Videos Comments

Two research teams working in the same laboratories in Australia have found distinct solutions to a critical challenge that has held back the realization of super powerful quantum computers. The teams created two types of quantum bits, or "qubits", which are the building blocks for quantum computers, that each process quantum data with an accuracy above 99%. They represent parallel pathways for building a quantum computer in silicon.

New sensor uses radio waves to detect subtle changes in pressure

October 10, 2014 2:09 pm Videos Comments

Stanford Univ. engineers have invented a sensor that uses radio waves to detect subtle changes in pressure. Already used to monitor brain pressure in laboratory mice as prelude to possible use with human patients, this pressure-sensing technology relies on a specially designed rubber and could lead to touch-sensitive “skin” for prosthetic devices.

Snakes and snake-like robots show how sidewinders conquer sandy slopes

October 10, 2014 8:15 am | by John Toon, Georgia Tech and Byron Spice, Carnegie Mellon Univ. Videos Comments

The amazing ability of sidewinder snakes to quickly climb sandy slopes was once something biologists only vaguely understood and roboticists only dreamed of replicating. By studying the snakes in a unique bed of inclined sand and using a snake-like robot to test ideas spawned by observing the real animals, both biologists and roboticists have now gained long-sought insights, including how sidewinders effectively traverse sandy slopes.

Nanoparticles get a magnetic handle

October 9, 2014 10:50 am | by David L. Chandler, MIT News Office Videos Comments

A long-sought goal of creating particles that can emit a colorful fluorescent glow in a biological environment, and that could be precisely manipulated into position within living cells, has been achieved by a team of researchers at Massachusetts Institute of Technology and several other institutions. The new technology could make it possible to track the position of the nanoparticles as they move within the body or inside a cell.

“Bellhops” in cell walls can double as hormones

October 8, 2014 9:29 am | by SLAC Office of Communications Videos Comments

Researchers have discovered that some common messenger molecules in human cells double as hormones when bound to a protein that interacts with DNA. The finding could bring to light a class of previously unknown hormones and lead to new ways to target diseases—including cancers and a host of hormone-related disorders.

Two Japanese, one American win Nobel for LED lights

October 7, 2014 9:10 am | by Karl Ritter and Malin Rising, Associated Press Videos Comments

Isamu Akasaki and Hiroshi Amano of Japan and U.S. scientist Shuji Nakamura won the 2014 Nobel Prize in physics for the invention of blue light-emitting diodes, a breakthrough that spurred the development of light-emitting diode (LED) technology. Scientists had struggled for decades to produce the blue diodes that are a crucial component in producing white light from LEDs when the three laureates made their breakthroughs in the early 1990s.

Trying on clothes when a shop is closed could become a reality thanks to new research that uses semi-transparent mirrors in interactive systems. The innovation, which builds on a mirror’s ability to map a reflection to one unique point behind the mirror, independently of the observer’s location, could change the way people interact and collaborate in public spaces, such as museums and shop windows.

A team of Georgia Institute of Technology researchers has created speech-to-text software for Google Glass that helps hard-of-hearing users with everyday conversations. A hard-of-hearing person wears Glass while a second person speaks directly into a smartphone. The speech is converted to text, sent to Glass and displayed on its heads-up display.

Untangling how cables coil

October 6, 2014 7:57 am | by Jennifer Chu, MIT News Office Videos Comments

The world’s fiber-optic network spans more than 550,000 miles of undersea cable that transmits Email, Websites and other packets of data between continents, all at the speed of light. A rip or tangle in any part of this network can significantly slow telecommunications around the world. Now, engineers have developed a method that predicts the pattern of coils and tangles that a cable may form when deployed onto a rigid surface.

A rip or tangle in any part of world’s 550,000-mile fiber-optic network can significantly slow telecommunications around the world. Now engineers have developed a method that predicts the pattern of coils and tangles that a cable may form when deployed onto a rigid surface. The research combined laboratory experiments with custom-designed cables, computer-graphics technology used to animate hair in movies, and theoretical analyses.

Washington State University undergraduate Kellie Wall, 21, recently looked for evidence that water influenced crystal formation in basalt, the dark volcanic rock that covers most of eastern Washington and Oregon. She then compared this with volcanic rock observations made by the rover Curiosity on Mars’ Gale Crater, inventing a new method for detecting water on Mars.

Study: Lift weights, improve your memory

October 2, 2014 9:21 am Videos Comments

A new Georgia Institute of Technology study shows that an intense workout of as little as 20 min can enhance episodic memory, also known as long-term memory for previous events, by about 10% in healthy young adults. The research isn’t the first to find that exercise can improve memory. But the study took a few new approaches, including testing memory after just single period of exercise.
