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.

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.

Catching
a crocodile or alligator to obtain a blood sample for testing is often
done at night by a boat or a canoe. A snout snare eases the process, but
it’s still a nerve-wracking experience. The samples are for the first
mapping project for crocodile and alligator genomes, and it’s also the
among the first such efforts to be done on a reptile species.

Blood
tests convey vital medical information, but the sight of a needle often
causes anxiety and results take time. A new device developed by a team
of researchers in Israel, however, can reveal much the same information
as traditional blood test in real-time, simply by shining a light
through the skin.

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?

A team from Tel Aviv University and the Hebrew University of Jerusalem has married biology and engineering to produce a biosensor device called the Dip Chip, which detects toxicity quickly and accurately, generating low false positive and false negative readings. The technology contains microbes designed to exhibit a biological reaction to toxic chemicals, emulating the biological responses of humans or animals.

A
research team at Rutgers University has been able to take a new
pharmacological approach to activate the immune cells to prevent cancer
growth through stimulation of the opiate receptors found on immune
cells.

The superbugs have met their match. Conceived at Nanyang Technological University, it comes in the form of a coating which has a magnetic-like feature that attracts bacteria and kills them without the need for antibiotics.

In
order to reactivate silenced genes, a cell needs to remove certain
“off” markers called methyl groups from the DNA. Scientists have
recently shown that this process involves an intermediate step and an
enzyme that also plays a role in the development of blood cancer. The
finding could lead to new ideas for cancer-fighting therapies.

A
pill that has long been used to treat HIV has moved one step closer to
becoming the first drug approved to prevent healthy people from becoming
infected with the virus that causes AIDS. The Food and Drug
Administration said Tuesday that Gilead Sciences' Truvada appears to be
safe and effective for HIV prevention.
