When the immune system defeats HIV

Experts at Johns Hopkins report compelling evidence that some asymptomatic people with HIV and remain symptom free without treatment do so because of a strong immune system.

Newly discovered molecular switch

Researchers have discovered a central molecular switch in fruit fly embryos that opens new avenues for studying the causes of birth defects and cancer in humans.

Reservoir of mitochondrial DNA mutations identified

An international team of researchers has revealed a large reservoir of mitochondrial DNA mutations present in the general population.

Common forebrain formation

Scientists have identified one of the molecular mechanisms underlying the genetic brain malformation called holoprosencephaly.

Reversing organ function decline

As people age, their cells become less efficient at getting rid of damaged protein - resulting in a buildup of toxic material that is...

Genetic basis for anxiety

Genetics may play a role in explaining why trauma causes some people to have bad memories while in others it causes post-traumatic stress disorder.

Recipe for cell reprogramming

A drug-like molecule called Wnt can be substituted for the cancer gene c-Myc, one of four genes added to adult cells to reprogram them to an embryonic-stem-cell-like state.

Faster genetic analysis of E. coli

Scientists have devised a novel method that allows rapid and large-scale studies of the E. coli genes.

Genetic variations in European Americans

Researchers have identified 200 positions in the DNA of European Americans that are responsible for the genetic diversity of one of the most diverse populations on Earth.

Cocaine damages foetal brains

Scientist Live spoke with Dr. Chun-Ting Lee about his research into the mechanism of how cocaine damage to foetal brains occurs.

Key to virulence protein discovered

Researchers have identified the region of a large family of virulence proteins in oomycete plant pathogens that enables the proteins to enter the cells of their hosts.

Gene found to protect liver

Researchers have discovered that a protein called FOXA2 controls the maintenance of proper levels of bile in the liver.

Alcohol tolerance influenced by miRNA

A new study now indicates that microRNA may influence the development of alcohol tolerance, a hallmark of alcohol abuse and dependence.

DNA change during depression and suicide

Autopsies usually point to a cause of death but now a study of brain tissue collected during these procedures, may explain an underlying cause of major depression and suicide.

Increasing crop efficiency

Scientists are genetically modifying plant root systems to improve their ability to find the water essential to their survival as a means of compensating for inefficient irrigation methods.
