Suppressing activity of common intestinal bacteria

Researchers has discovered that common intestinal bacteria appear to promote tumour growths in genetically susceptible mice, but that tumorigenesis can be suppressed if the mice are exposed to an inhibiting protein enzyme.

Viruses against cancer

Particular parvoviruses do not cause any disease symptoms in humans, but kill infected tumours cells without causing any damage to healthy tissue.

Supplements induce stem cell genetic abnormalities

High doses of antioxidant nutritional supplements, such as vitamins C and E, can increase genetic abnormalities in cells, which may predispose supplement-takers to developing cancer, according to a new study.

Unmasking anthrax for immune destruction

Anthrax-causing bacteria can be engineered to shed their invisibility cloaks, making it easier for the immune system to eradicate it, according to a new study.

Fighting fungal infections with bacteria

A bacterial pathogen can communicate with yeast to block the development of drug-resistant yeast infections, say Irish scientists.

A molecular fishing trip

Scientists went on a molecular fishing trip and netted a catch of new mediators that not only can explain how omega-3 fatty acids reduce inflammation, but also hint at novel treatments for a host of diseases linked to inflammatory...

'Junk DNA' drives cancer growth

Recent studies have identified how 'junk' DNA promotes the growth of cancer cells in patients with Hodgkin's lymphoma.

Rapid Chagas disease diagnosis

A reliable and rapid diagnosis is the key in the battle against Chagas disease infection but until now, this has been next to impossible.

Brain-like computing on an organic molecular layer

In our brains, information processing circuits-neurons-evolve continuously to solve complex problems. An international research team has created a similar process of circuit evolution in an organic molecular layer that can solve complex...

Structure of inner-ear protein dictates disease

A team of researchers has discovered how the structure of a vital region of cadherin-23, one of two proteins that join to form each tip link, relates to the hearing process.

Biting Back Against the Tetse Fly

Researchers at the University of St Andrews are one step closer to breaking the tetse fly's grip on Africa's health and economy.

Variation in those infected by H1N1

An analysis of blood samples taken before, during and after an epidemic wave of influenza A in Singapore in 2009 finds variation in...

Progress in understanding protein architecture

Researchers in Singapore are reporting this week that they have gleaned key insights into the architecture of a protein that controls iron levels in almost all organisms.

Harnessing viruses to split water

A team of researchers has found a novel way to mimic the process by which plants use the power of sunlight to split water and make chemical fuel to power their growth.

Building a better flu vaccine

Vaccines likely would work better in protecting children from flu if they included both strains of influenza B instead of just one, Saint Louis University research has found.

Novel class of antibodies inhibits HIV infection

Scientists have identified a set of naturally occurring antibodies that can block one of the key ways the AIDS virus gains entry into certain blood cells.

Defective protein is a double hit for ataxia

Researchers now report that the defective protein responsible for spinocerebellar ataxia type 5 cuts the number of synaptic terminals and snarls traffic inside neurons.

Better way to track stem cells

Using Indocyanine Green to label human embryonic stem cell-derived cardiomyocytes substantially improved efforts to optically track stem cells after transplanting them into heart tissues.

Structure of key protein in common HIV subgroup

Scientists have provided the first-ever glimpse of the structure of a key protein-gp120-found on the surface of a specific subgroup of the...

Fat clue to TB awakening

The factors instrumental in triggering latent tuberculosis infection to progress into active disease have long remained elusive to researchers.
