New insight into the controls on a vital enzyme
Scientists at St. Jude Children’s Research Hospital have gained new insights into regulation of one of the body’s enzyme workhorses called calpains.

Study helps clarify role of vitamin D in cancer therapy
A colon cancer cell isn’t a lost cause. Vitamin D can tame the rogue cell by adjusting everything from its gene expression to its cytoskeleton.

Open access pilot in FP7
The European Commission has launched an open access pilot in the Seventh Framework Programme (FP7).
17 November 2008
New bacteria discovered in raw milk
Raw milk is illegal in many countries as it can be contaminated with potentially harmful microbes.
14 November 2008
A single gene leads yeast cells to cooperate against threats
An ingenious social behaviour that mobilizes yeast cells to cooperate in protecting each other from stress and other dangers is driven by the activity of a single gene, reports this week’s Cell.
13 November 2008
Rheumatoid arthritis breakthrough
Rheumatoid arthritis is a painful, inflammatory type of arthritis that occurs when the body’s immune system attacks itself.

Without enzyme, biological reaction essential to life would take 2.3 billion years
All biological reactions within human cells depend on enzymes. Their power as catalysts enables biological reactions to occur usually in milliseconds.
11 November 2008
Can we mutate viruses to death?
It sounds like a science fiction film: a killer contagion threatens the Earth, but scientists save the day with a designer drug that forces the virus to mutate itself out of existence.
10 November 2008
HIV’s disguises no match for ‘bionic assassins’
HIV is a master of disguise, able to rapidly change its identity and hide undetected in infected cells.
7 November 2008
Is stuttering in our DNA?
Stuttering afflicts 5% of all children — and a childhood blighted by stuttering can be traumatic, producing educational, social, and career disadvantages.
6 November 2008
Death by hyperdisease
It took less than a decade for native rats to become extinct on the Indian Ocean’s previously uninhabited Christmas Island once Eurasian black rats jumped ship onto the island at the turn of the 20th century.
5 November 2008
Tree of knowledge
A new web site makes it easier for researchers to keep track of the latest developments in their field; the latest people, papers and talks.
4 November 2008
New research could be the ‘holy grail’ for predicting pre-eclampsia
New research funded by the British Heart Foundation could pave the way for developing a test to predict pre-eclampsia in pregnant women and save the lives of mothers and babies across the world.
3 November 2008
New method provides panoramic view of protein-RNA interactions in living cells
Methodological problems have historically plagued the study of RNA regulation in living cells, limiting not only the accuracy of results but also the understanding of RNA’s role in human disease.

New mouse mutant contains clue to progressive hearing loss
Researchers have defined a mutation in the mouse genome that mimics progressive hearing loss in humans.
30 October 2008
Researchers find new chemical key to hundreds of new antibiotics
Researchers at The University of Warwick and the John Innes Centre, have found a novel signalling molecule that could be a key that will open up hundreds of new antibiotics unlocking them from the DNA of the Streptomyces family of bacteria.
29 October 2008
New cell division mechanism discovered
A novel cell division mechanism has been discovered in a micro-organism that thrives in hot acid.
28 October 2008
How proteins are made and placed
Stanford University School of Medicine researchers have uncovered what appears to be an extensive, but until now barely noticed, network of regulatory interactions that influence what proteins are made inside a cell, and when and where.
27 October 2008
First comprehensive genomic study of common cold
Scientists from Procter & Gamble (P&G), the University of Calgary and the University of Virginia have announced results from the first study to examine the entire human genome's response to the most common cold virus, human rhinovirus.
24 October 2008
Worms live longer if they can’t smell
Many animals live longer when raised on low calorie diets. But now researchers have shown that they can extend the life spans of roundworms even when the worms are well fed — it just takes a chemical that blocks their sense of smell.
23 October 2008
How antibiotic sets up road block to kill bacteria
Scientists have taken a critical step toward the development of new and more effective antibacterial drugs by identifying exactly how a specific antibiotic sets up a road block that halts bacterial growth.
22 October 2008
European researchers harness unique properties of boron for new drugs and diagnostics
Researchers are on the verge of unleashing the power of the element boron in a new generation of drugs and therapies, as decades of research begins to bear fruit.
21 October 2008
Getting to grips with the complexity of disease proteins
Drug molecules seldom act simply on one protein but on protein complexes and networks. A deeper understanding of these 'cooperative assemblies' should lead to better targeting of drugs.
20 October 2008
Researchers successfully generate stem cells from a single hair
The first attempts to reprogram adult human cells back into so-called induced pluripotent stem (iPS) cells were woefully inefficient: only one out of 10,000 cells could be persuaded to turn back the clock.
17 October 2008
Gene therapy restores vision to mice with retinal degeneration
Massachusetts General Hospital (MGH) researchers have used gene therapy to restore useful vision to mice with degeneration of the light-sensing retinal rods and cones, a common cause of human blindness.
16 October 2008
PEER review
A new collaboration between publishers, repositories and the research community has been launched to look at the effects of the systematic depositing of authors’ final peer-reviewed manuscripts.
15 October 2008
Compound that stabilizes p53
A study performed by IRB Barcelona and ICIQ on the p53 protein opens up a new strategy for the development of anti-tumour drugs.
14 October 2008
Lack of vitamin D linked to Parkinson's disease
A majority of Parkinson's disease patients had insufficient levels of vitamin D in a new study from Emory University School of Medicine.
13 October 2008
Pectin power
Scientists at the Institute of Food Research have found a new possible explanation for why people who eat more fruit and vegetables may gain protection against the spread of cancers.
