World first trial grows blood vessels from patient's own skin

A team of American scientists have successfully implanted blood vessels grown entirely from a patient's own cells.

Circadian rhythm - two key groups of neurons control morning and evening activity

A Brandeis University study published in Nature shows for the first time that a molecular signal maintains coherence among brain clock cells that regulate daily activity of Drosophila melanogaster (fruit flies).

Cellular signal may determine life or death for damaged brain cells

Scientists at the Universities of Heidelberg and Ulm and a unit of the European Molecular Biology Laboratory (EMBL) in Monterotondo, Italy, have discovered that a specific signal within brain cells may determine whether they live or die after a stroke.

Scientists discover why lung, but not skin, anthrax infections are lethal

Scientists from the Max Planck Institute for Infection Biology in Berlin discovered why lung, but not skin, anthrax infections are lethal. As reported in the newest issue of PloS Pathogen (November 2005) Neutrophils, a form of white blood cells, play a key role in anthrax infections.

Tiny worms provide clues to new treatments for diabetes, asthma and hay fever

University of Edinburgh scientists, who have discovered that helminth parasites can exploit an 'Achilles heel' in our immune system, now hope to mimic the worms' survival tactics in a bid to beat infection.

Gene doping is a real danger - but anti-doping science is making progress

Gene therapy research has reached a critical phase. Already practised on humans as part of strictly controlled experiments, gene therapy promises to become a widely available form of treatment for injury and disease.

Scientists find new mechanism by which brain cells can be damaged during chronic neurodegenerative diseases

Scientists at the University of Rochester Medical Center have targeted a new culprit and method of attack on neurologic functions in diseases such as Alzheimer's and dementia associated with HIV.

Gene silencing and microRNA discovery

One of the body's primary strategies for regulating its genome is a kind of targeted gene silencing orchestrated by small molecules called microRNAs, or miRNAs.

New way to generate genetically altered influenza virus

In the event of an influenza pandemic, the world's vaccine manufacturers will be in a race against time to forestall calamity.

How the brain tracks time is essential to understanding all its functions

The brain is a "time machine," assert Duke neuroscientists Catalin Buhusi and Warren Meck. And understanding how the brain tracks time is essential to understanding all its functions. The brain's internal clocks coordinate a vast array of activities from communicating, to orchestrating movement, to getting food, they said.

Analytical method to trace the lineage trees of cells

Some fundamental outstanding questions in science - "Where do stem cells originate?" "How does cancer develop?" "When do cell types split off from each other in the embryo?" - might be answered if scientists had a way to map the history of the body's cells going back to the fertilized egg.

Cichlid fish provide better understanding of the genetic factors that regulate bone shape

Researchers at the Forsyth Institute have discovered that the genes that influence the jaws of cichlid fish, tropical freshwater fish renowned for head shape diversity, offer insight into overall vertebrate diversity.

Trigger discovered that causes stem cells embryos to start developing into organs

They have apparently discovered the chemical trigger that causes stem cells from embryos to start developing into organs, raising the possibility of parts of the body being able to repair their own damage.

HapMap will give clues to many common diseases

Researchers say that they have completed a map that charts patterns of human genetic variation in the world population, to better understand human biology, evolution and how to diagnose diseases.

New understanding of how neurogenesis occurs

Scientists at the Salk Institute for Biological Studies have identified a crucial cellular signal that controls the fate of stem cells in the brains of adult mice.

Scientists have identified the gene which explains why eggs fail to produce a zygote

Scientists have identified the gene responsible for controlling a first key step in the creation of new life, according to new research published in the journal Nature.

Mechanisms of evolution may be associated with disease

By comparing the human genome with that of the chimpanzee, man's closest living relative, researchers have discovered that chunks of similar DNA that have been flipped in orientation and reinserted into chromosomes are hundreds of times more common in primates than previously thought.

Gold nanorods injected into the bloodstream may be used to develop an advanced medical imaging tool

Researchers at Purdue University have taken a step toward developing a new type of ultra-sensitive medical imaging technique that works by shining a laser through the skin to detect tiny gold nanorods injected into the bloodstream.

New technique reveals the strength of bones

Scientists have developed a technique which can be used to reveal the strength of bones, allowing doctors to more accurately estimate the risk of bone fracture.

How cells use very slow biological flows to signal and organize

An EPFL (Ecole Polytechnique Federale de Lausanne) team led by professor Melody Swartz has demonstrated for the first time that the presence of very slow biological flows affects the extracellular environment in ways that are critical for tissue formation and cell migration.
