There's nothing like a new pair of eyeglasses to bring fine details into sharp relief. For scientists who study the large molecules of life from proteins to DNA, the equivalent of new lenses have come in the form of an advanced method for analyzing data from X-ray crystallography experiments. The findings could lead to new understanding of the molecules that drive processes in biology, medical diagnostics, nanotechnology, and other fields.

The scientific and technological literature is abuzz with nanotechnology
and its manufacturing and medical applications. But it is in an area
with a
less glitzy aura—plant sciences—where nanotechnology advancements are
contributing dramatically to agriculture. Researchers at Iowa
State University
have now demonstrated the ability to deliver proteins and DNA into plant
cells,
simultaneously.

Researchers in Germany have for years been studying fire beetles of the genus <i>Melanophila</i>
and their sophisticated infrared sensors, which these pyrophilous
insects use to detect forest fires. They have unraveled the functional
principle of this photomechanical sensor and have started to work on a
technical reconstruction.

In
the course of its evolution, the architecture of the mouse brain may
have barely changed. In fact, researchers point to it as a “living
fossil” of brain development, preserving our ancestors’ neuronal
circuits’ architecture. Comparative analysis now shows where those
changes occurred after the extinction of dinosaurs and the growth of
mammals.

The
highly pathogenic hantavirus causes a condition known as hantavirus
pulmonary syndrome (HPS), which has a case fatality rate of 35-40%. To
help the fight against a disease that has no vaccine, U.S. Army
scientists and industry collaborators have successfully protected
laboratory animals from lethal hantavirus disease using a novel approach
that combines DNA vaccines and duck eggs.

The current method of removing the greenhouse gas carbon dioxide from the flues of coal-fired power plants uses so much energy that no one bothers to use it. So says Roger Aines, principal investigator for a team that has developed an entirely new catalyst for separating out and capturing carbon dioxide, one that mimics a naturally occurring catalyst operating in our lungs.

Getting a shot at the doctor's office may become less painful in the not-too-distant future. Massachusetts Institute of Technology researchers have engineered a device that delivers a tiny, high-pressure jet of medicine through the skin without the use of a hypodermic needle. The device can be programmed to deliver a range of doses to various depths—an improvement over similar jet-injection systems that are now commercially available.

A new collaboration between Oxford University
and the Lausanne Museum of Zoology will use the latest genetic
techniques to
investigate organic remains that some have claimed belong to the 'Yeti'
and
other 'lost' hominid species.
