Yale University engineers have developed a novel automated system for generating strong, flexible, transparent coatings with promising uses in lithium-ion battery and fuel cell production, among other applications. The system, called spin-spray layer-by-layer, cuts process time and produces films with both nanolevel precision and improved function.

A
group of scientists took to the skies in a slow-moving airship Thursday
in search of meteorites that rained over California's gold country last
month. It's the latest hunt for extraterrestrial fragments from the
April 22 explosion that was witnessed over a swath of Northern
California and Nevada.

A
new look at a 425-year-old map has yielded a tantalizing clue about the
fate of the Lost Colony, the settlers who disappeared from North
Carolina's Roanoke Island in the late 16th century. Researchers are
focusing on he "Virginea Pars" map of Virginia and North Carolina
created by explorer John White in the 1580s. It was intended to be an
accurate map, but what interests scientists are the two patches attached
to it.

Researchers at Massachusetts Institute of Technology and Georgia Institute of Technology have developed a way to automate the process of finding and recording information from neurons in the living brain. The researchers have shown that a robotic arm guided by a cell-detecting computer algorithm can identify and record from neurons in the living mouse brain with better accuracy and speed than a human experimenter.

A team of scientists has been working to develop nanocrystallography techniques that can be used in ordinary science settings. They have shown how a powerful method called atomic pair distribution function (PDF) analysis can be carried out using a transmission electron microscope.

Long before freeways and parking lots, a naturally occurring asphalt first appeared on roads in about 600 B.C. You can still see patches of it in the ancient city of Babylon. Under the onslaught of 21st century traffic, modern asphalt isn’t likely to hold up for anywhere near 2,700 years. But at Michigan Technological University, Zhanping You is paving the way for brand-new asphalt blends to fight off cracks, rutting, and potholes.

An
international team of researchers has discovered how adding trace
amounts of water can tremendously speed up chemical reactions—such as
hydrogenation and hydrogenolysis—in which hydrogen is one of the
reactants, or starting materials. Previous research had indicated this
phenomenon, but until now the true importance of water to its effect has
eluded chemists.

While many are focusing on atmospheric solutions to reduce greenhouse gases, some researchers are setting their sights on the ground—deep underground. Li Li, an assistant professor of energy and mineral engineering at Penn State University, is investigating geologic carbon sequestration as a way to reduce the amount of carbon dioxide in the atmosphere.

Condensed-matter physicists the world over are in hot pursuit of a comprehensive understanding of high-temperature superconductivity, not just for its technological benefits but for the clues it holds to strongly correlated electron systems. One important avenue of investigation is pairing symmetry.

Researchers at Massachusetts Institute of Technology, NASA, and elsewhere have detected a possible planet, some 1,500 light years away, that appears to be evaporating under the blistering heat of its parent star. The scientists infer that a long tail of debris is following the planet, and that this tail may tell the story of the planet's disintegration.

In
a recent project that has challenged the notion that the best chip is
the most accurate one, a research team has unveiled this week its
prototype “inexact” computer chip. By allowing the chip to make a few
mistakes, developers were able to slash the power consumption of the
chip dramatically. The result is a chip at least 15 times more efficient
than today’s technology.

Plants
rely on photoreceptors to activate internal chemical processes like
germination and leaf growth. Theorizing that the light-absorbing
component of the photoreceptor may be replaced by a chemically similar
synthetic substance, scientist have for the first time shown that full
growth of plants is possible in the complete absence of light.

The U.S. Food and Drug Administration (FDA)
generally approves drug therapies faster and earlier than its
counterparts in Canada and Europe,
according to a new study by Yale University School of Medicine
researchers. The
study counters perceptions that the drug approval process in the U.S. is
especially slow.

Not
long after a partially paralyzed man in Switzerland used his mind to
remotely control a small robot, a Massachusetts woman paralyzed for 15
years used only her thoughts to direct a robotic arm to pick up a bottle
of coffee and bring it to her lips But will the experimental
brain-controlled technology ever help paralyzed people in everyday life?

Technology is helping
communication companies merge telephone, television, and Internet
services, but
a push to deregulate may leave some customers on the wrong side of the
digital
divide during this convergence, according to a Penn State University
telecommunications
researcher.
