new discovery

A new discovery about a 2,000-year-old Chinese herbal remedy derived from the roots of the blue evergreen hydrangea may pave the way for a new generation of more targeted treatments for autoimmune disorders.

(University of Calgary) Researchers have uncovered a mechanism by which stress increases food drive in rats. This new discovery, published online this week in the journal Neuron, could provide important insight into why stress is thought to be one of the underlying contributors to obesity.

(Trudeau Institute) Researchers from Dr. Woodland's lab at the Trudeau Institute have now identified a previously unknown link between the migration of white blood cells to infected tissues and the ability of these cells to survive and become long-lived memory cells after the infection has been cleared.

The new data is featured on the cover of this month's the Journal of Experimental Medicine.

(Federation of American Societies for Experimental Biology) Are you genetically predisposed to tuberculosis? Scientists may now be able to answer this question and doctors may be able to adjust their therapeutic approach based on what they learn.

That's because new research presented in the Journal of Leukocyte Biology suggests that two frequent mutations in an immune system gene called TLR1 are responsible cellular changes that ultimately make us less likely to resist the disease.

(Trudeau Institute) Researchers from the Smiley lab at the Trudeau Institute have now identified a single component of the plague causing bacterium that can be used as a vaccine.

This single "subunit" could potentially be used to create a safer form of a T cell-stimulating plague vaccine.

The new data is featured in the July issue of the Journal of Immunology.

(Wake Forest Baptist Medical Center) A new discovery in mice by researchers at Wake Forest Baptist Medical Center may one day allow doctors to spare some patients with acute myeloid leukemia (AML) from toxic treatments, while also opening the door for new therapeutic research.

(Swiss Federal Laboratories for Materials Science and Technology (EMPA)) Nanosilver is not a new discovery by nanotechnologists -- it has been used in various products for over a hundred years, as is shown by a new Empa study.

The antimicrobial effects of minute silver particles, which were then known as "colloidal silver," were known from the earliest days of its use.

A new discovery may push back the earliest evidence of stone tool use by human ancestors another 800,000 years, to at least 3.2 million years ago

(Rutgers University) Nihal Altan-Bonnet, assistant professor of cell biology, Rutgers University in Newark, and her research team have made a significant new discovery about RNA (Ribonucleic acid) viruses and how they replicate themselves.Certain RNA viruses -- Poliovirus, Hepatitis C virus and Coxsackievirus -- and possibly many other families of viruses copy themselves by seizing an enzyme from their host cell to create replication factories enriched in a specific lipid.

A new discovery may help explain why the universe exists at all. Interested?
