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.

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.

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
year-long evaluation of the effect of quantum dots in primates has
found the nanoparticles to be safe, encouraging doctors and scientists
who are hoping to use them to battle diseases like cancer. Cadmium
selenide quantum dots were the variety used in the study.

The
U.S. government has been pushing doctors to e-prescribe, in part
because it can be safer for patients. Now, more than a third of the
nation's prescriptions now are electronic, and starting this year,
holdouts will start to see cuts in their Medicare payments.

Instead of building a better mousetrap, a team of Rice University freshmen took a mousetrap and built a better way to treat dehydration among children in the developing world. The device, designed by the IV DRIP (Dehydrated Relief in Pediatrics) team, is inexpensive and regulates the amount of fluid delivered to children to prevent dehydration.

Researchers have created an ultrasensitive biosensor that could open up new opportunities for early detection of cancer and "personalized medicine" tailored to the specific biochemistry of individual patients. The device, which could be several hundred times more sensitive than other biosensors, combines the attributes of two distinctly different types of sensors.

Scientists
at Weill Cornell Medical College have discovered that the single
protein, alpha 2 delta, exerts a spigot-like function that controls the
volume of neurotransmitters and other chemicals that flow between the
synapses of brain neurons. The surprising finding tells us not only how
brain cells communicate, but also how a certain pain drug works.

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.

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.
