Synthetic bone graft recruits stem cells

A new study shows how particles of a ceramic called calcium phosphate have the ability to stimulate promising bone regrowth by attracting stem cells and 'growth factors' to promote healing and the integration of the grafted tissue.

Why MRC said no to in vitro fertilisation

An intriguing paper published in Europe's leading reproductive medicine journal Human Reproduction reveals for the first time the reasoning behind the MRC's much-criticised decision.

Key enzyme repairs sun-damaged DNA

Researchers have long known that humans lack a key enzyme - one possessed by most of the animal kingdom and even plants - that reverses severe sun damage.

Blocking key pathway in prostate cancer

Prostate cancer advances when tumors become resistant to hormone therapy, which is the standard treatment for patients, and begin producing their own androgens.

Unique parallel peptide synthesizer

The Syro Wave peptide synthesis system is the only system on the market that offers both microwave and parallel peptide synthesis capabilities.

Antibody response trigger discovered

Researchers have discovered a trigger that induces B cells to produce effective and long-lived antibodies early in the immune response.

Neuronal remote control

Clusters of heated, magnetic nanoparticles targeted to cell membranes can remotely control ion channels, neurons and even animal behavior, according to a paper.

How T cells make a commitment

When does a cell decide its particular identity? In the case of T cells-immune system cells that help destroy invading pathogens-the answer is when the cells begin expressing a particular gene called Bcl11b.

Original HIV Infection Lurks Within

Scientists have been surprised to learn that, despite thousands of changes that viruses like HIV undergo in rapid fashion to evade the body's immune system, the original version that caused the infection is still present in the body months...

Deaths in the family cause bacteria to flee

Exposure to the extracellular DNA released by dying neighbours stops the sticky holdfasts of living Caulobacter from adhering to surfaces, preventing cells from joining bacterial biofilms.

Component helps plants go green

A team of researchers from Duke University and the Salk Institute for Biological Studies has found a central part in the machinery that turns plants green when they sense light.

Campaign for elimination of lymphatic filariasis

Researchers identified barriers to compliance with India's MDA program for LF, and suggest that timely educational and lymphedema management programs can reverse this trend.

Degenerative disease trigger identified

A mechanism that regulates stem-cell differentiation in mice testes suggests a similar process that may trigger degenerative disease in humans, according to a physiologist.

Viral protein structure study offers HIV hope

The UK's National Physical Laboratory is involved in a collaborative project that is helping to further the understanding of HIV viral protein structure which could lead to new molecular medicines.

Vascular malformations in the brain

Benign vascular malformations known as cavernomas can occur in many tissues of the body. Researchers are investigating how blood vessels and lymphatic vessels are newly formed in tumour diseases.

Septet controls platelet clotting

In what is believed to be the largest review of the human genetic code to determine why some people's blood platelets are more likely to clump faster than others, scientists have found a septet of overactive genes, which they say likely...

Key Enzyme in Melanoma Cell Development

Researchers have discovered a mechanism by which an enzyme regulates gene expression and growth in melanoma cells, a finding that could someday lead to more effective drugs to attack cancers and make them more treatable.

Therapeutic potential of embryonic stem cells

The therapeutic potential of embryonic stem cells has been an intense focus of study and discussion in biomedical research and has resulted in technologies to produce human induced pluripotent stem cells.

New strategy to fight cancer drug resistance

Scientists at Dana-Farber Cancer Institute have found a way to disable a common protein that often thwarts chemotherapy treatment of several major forms of cancer.

Flu's Evolution Strategy Strikes Perfect Balance

Scientists have uncovered the flu's secret formula for effectively evolving within and between host species. The key lies with the flu's unique replication process.
