Vaccine puts blood-sucking ticks off their food
A new solution to controlling tick-borne diseases of animals and humans is the development of vaccines against the ticks and not the microbes that cause the diseases.

Study confirms seasonal fluctuation in immunity-generating cells among MS patients
Through a first-ever longitudinal study, researchers have confirmed that T-cells (white blood cells that fight infection and disease in healthy individuals) show seasonal fluctuation in multiple sclerosis (MS) patients, and that the T-cells were at a high in the autumn months.

Fatty acid could offset postpartum depression and improve babies' development
Pregnant or nursing women may be able to reduce their chances of developing postpartum depression and improve the neurological development of their babies by increasing their consumption of the essential fatty acid DHA, an omega-3 fatty acid mostly found in fish like tuna and salmon and in algae.

Jefferson study shows low concentrations of chemotherapy drugs have antiangiogenic effects
New studies in mice indicate low doses of chemotherapy drugs given more frequently than usual and in tinier doses may target the process by which a new blood supply is created feeding tumor growth, called angiogenesis.

Designers and analysts often ask themselves questions such as:

Researchers link stroke patients' anger and aggression to brain injury
The anger and irritability stroke patients exhibit may have more to do with an injury to the brain during the stroke than it does post-stroke depression, according to a study published in Neurology, the scientific journal of the American Academy of Neurology.

Tool pinpoints acceptable pricing of combination vaccines
Four infant vaccines. One injection. How much will the industry charge?

People who drink tea may be doing more than soothing a weary stomach--they might be preventing cancer, according to researchers at the Keck School of Medicine of USC and colleagues.

Hydrogel nanoparticles provide foundation for tunable photonic crystals via controlled de-swelling
Researchers at the Georgia Institute of Technology have developed a family of hydrogel-based nanoparticles that can be used to form photonic crystals whose optical properties can be precisely tuned by thermally adjusting the particles' water content.

Cell Pathways' CP461 demonstrates multiple anti-cancer activities
CP461, an oral inhibitor of PDE1 and PDE5 now in Phase II clinical trials, increased survival in a rat model of human non-small cell lung cancer equivalent to that produced by injected Taxotere® (docetaxel), the currently approved chemotherapeutic for NSCLC.

The next generation of computers will be timeless
Faster, smaller computers are at an advanced stage of development in university research labs and will soon be replacing existing technology, claim scientists this week.
