University of Michigan researchers have proven that a special surface, free of biological contaminants, allows adult-derived stem cells to thrive and transform into multiple cell types. Their success brings stem cell therapies another step closer.

Researchers
at the U.S. Air Force Research Laboratory have invented a simple,
inexpensive dip-and-dry treatment can convert ordinary silk into a
fabric that kills disease-causing bacteria—even the armor-coated spores
of microbes like anthrax—in minutes.

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.

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.

Biomedical engineers at University of California, Davis have
developed a microfluidic chip to test for latent tuberculosis. They hope
the
test will be cheaper, faster, and more reliable than current testing for
the
disease.

A biomedical informatics researcher who tracks dangerous viruses as they spread around the globe has restructured his innovative tracking software to promote even wider use of the program around the world.

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.

Hundreds
of tiny hollow needles stick out of the membrane of a bacteria that
causes cholera. These are treacherous tools that makes bacterial
pathogens so dangerous. Researchers in the U.S. and Germany have now
seen this structure in 3D detail at atomic resolution. The images may
help drug researchers.

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.
