Why our immune system worsens with age

Scientists at the Vaccine and Gene Therapy Institute at Oregon Health & Science University have made a discovery that helps explain why our immune system worsens with age. The work was led by Janko Nikolich-Zugich, M.D., Ph.D., a senior scientist at the VGTI.

Tofu-based biomaterial that can help mend broken bones

A new Tofu-based biomaterial that can help mend broken bones and damaged tissues is being developed thanks to an investment of £149,000 from NESTA (the National Endowment for Science, Technology and the Arts), the organization that champions UK creativity and innovation.

Scientists create world’s smallest test tube

Oxford scientists have made it into the Guinness Book of World Records by making the world’s smallest test tube – so tiny that around 300 billion would fit onto a full stop on this page.

Scientists have determined the crystal structure of a protein kinase C (PKC) isozyme

This structure should prove extremely useful in the rational design of small molecule inhibitors of PKCÈ, which has been implicated in T-cell mediated disease processes including inflammation and autoimmunity.

Transport route explain why peanuts are one of the most allergenic foods

A UK scientist has discovered the route and type of transport taken by peanut proteins through the gut to the immune system. This route favours an immune response, which helps explain why peanuts are one of the most allergenic foods.

Sex genes of infectious fungus closely resemble human Y chromosome

Fungi and animals, including humans, have a lot in common when it comes to the arrangement of genes that determine their sex, according to new work by Howard Hughes Medical Institute geneticists at the Duke University Medical Center.

Stem cell gene linked to a portion of one of the most common childhood brain cancers

Scientists at Johns Hopkins have linked a stem-cell gene to a portion of one of the most common childhood brain cancers, opening the door to tailored therapies that block the gene's tumor-promoting ability.

Scientists have developed a fast and safe method for collecting heart stem cells from small amounts of biopsied heart tissue

In human and animal studies, scientists at Johns Hopkins have developed a fast and safe method for collecting heart stem cells from remarkably small amounts of biopsied heart tissue (15 mg or less), and growing the cells in the lab to get more.
