Scientists reveal the important role of early experience in shaping neuronal development

Scientists at New York University School of Medicine reveal the important role of early experience in shaping neuronal development and brain plasticity in a new study published in the July 14 issue of the journal Nature.

Carbon nanotubes may change the way doctors treat broken bones

Scientists have shown for the first time that carbon nanotubes make an ideal scaffold for the growth of bone tissue. The new technique could change the way doctors treat broken bones, allowing them to simply inject a solution of nanotubes into a fracture to promote healing.

Scientists discover how an HIV protein fragment shuts down an immune response

The HIV virus hides out in the very immune system cells that are meant to protect the body from viral infection. But how does it prevent these cells from mounting a full-scale attack against the invader?

Scientists discover identifying markers for primitive blood-forming stem cells - simplifies cell identification

Scientists at the University of Michigan Medical School have discovered the biological equivalent of a grocery store bar code on the surface of primitive, blood-forming stem cells in mice. Called hematopoietic stem cells, they give rise to all the different types of specialized cells found in blood.

Protein that was thought to simply turn genes on and off now looks to be more like a cellular dimmer switch

The scientists showed for the first time that when certain parts of a protein molecule are modified - flexible, randomly structured regions believed to be only minor players in the protein world - they become important in turning genes on and off, but in a way that resembles a dimmer switch rather than an on-off switch.

Rain forest tree gives new hope for psoriasis sufferers

A team of scientists at University of Newcastle upon Tyne have discovered that an ointment, dithranol, used to soothe psoriasis actually kills the cells that cause the problem.

Scientists aim to mislead malaria mosquitoes with odours

An international team of scientists will in the coming five years set up a research project on developing diversions to mislead malaria mosquitoes with odours.

Adult, or post-natal, stem cells have the same ability as embryonic stem cells to multiply

In a ground-breaking study, scientists at Children's Hospital of Pittsburgh have discovered that adult, or post-natal, stem cells have the same ability as embryonic stem cells to multiply, a previously unknown characteristic indicating that post-natal stem cells may play an important therapeutic role.

Scientists have discovered how C-reactive protein is able to access endothelial cells

For the first time, scientists have discovered how C-reactive protein, or CRP, is able to access endothelial cells. The UC Davis researchers' findings will be published in the July issue of Arteriosclerosis, Thrombosis, and Vascular Biology, one of the American Heart Association's leading journals.

Scientists solve structure of a critical innate immune system protein

Scientists at The Scripps Research Institute have solved the structure of a crucial human immune system molecule called TLR3, an acronym for Toll-like receptor three. In an upcoming issue of the journal Science, the protein is described as a large horseshoe-shaped coil composed of 23 leucine-rich repeats (LRRs).

If you know how viruses get into cells, you know how to better design drugs to keep them out

When it comes to gaining entry into cells, size matters. A team from Brown University and the Max Planck Institute for Metals Research has created a model that explains how viruses and other bioparticles slip inside cells without a special protein coating called clathrin.

Scientists successfully isolate stem cells from human skin

Scientists at Wake Forest University School of Medicine have successfully isolated stem cells from human skin, expanded them in the laboratory and coaxed them into becoming fat, muscle and bone cells.

Light used to regulate protein synthesis

Proteins are the puzzle-pieces of life, involved in how organisms grow and flourish, but studying their complex biological processes in living systems has been extremely difficult.

Scientists identify inhibitors of the anthrax toxin

A collaborative team of scientists led by The Burnham Institute's Maurizio Pellecchia, Ph.D., has identified inhibitors of the anthrax toxin, termed lethal factor ("LF") that could be developed into an emergency treatment for exposure to inhalation anthrax.

Finding may impact understanding of mechanical facets of many diseases

An international team led by Jeffrey J. Fredberg, professor of bioengineering and physiology at the Harvard School of Public Health, has found that the cell modulates its mechanical properties in much the same way as a glassblower shapes fine glassware.

Early embryos with abnormal chromosomes are capable of returning to normal when grown in culture in the laboratory

While such embryos are not capable of developing into normal foetuses if implanted in a woman's womb, the discovery has important implications for stem cell production, especially in countries where the creation of embryos for stem cell research is discouraged or even banned.
