Meningitis bacteria dress up as human cells

The way in which bacteria that cause bacterial meningitis mimic human cells to evade the body's innate immune system has been revealed by researchers.

Standardised language for describing microbes

Scientists make progress in developing a universal language to describe the genes involved in the complex interplay between microbes and the hosts that they colonise.

Software speeds enzyme design

Computer scientists and biochemists have developed and laboratory-tested a computer program that can show experimentalists how to change the machinery that bacteria use to make natural antibiotics.

5 million atoms in viral coat

An image indicates that a viral capsid contains some 5 million atoms and it could help scientists find better ways to both fight viral infections and design new gene therapies.

Chronic infection cripples developing world

New research from MIT indicates that underlying, low-level undiagnosed infection may greatly add to the severity of a significant number of these cases.

Deathly awakening by interferon

Hematopoietic stem cells remain dormant throughout their lives and are only awakened to activity in case of injury and loss of blood. Then they immediately start dividing to make up for the loss of blood cells.

Major step for drug discovery and diagnostics

Researchers have developed a method that can be used to screen several thousand proteins and will reduce the way from development to useful drugs substantially.

Genetic adaptations key to microbe's survival

The genome of a marine bacterium living 2,500 meters below the ocean's surface is providing clues to how life adapts in extreme thermal and chemical gradients, according to an article recently published.

Controlling intracellular protein delivery

Scientists have uncovered the Transformer like properties of molecules responsible for carrying and depositing proteins to their correct locations within cells.

Wireless drug control

Electronic implants that dispense medicines automatically or via a wireless medical network are on the horizon, but experts warn of security risks.

Protein hints at gene switch mechanism

The bacterium behind tuberculosis is helping researchers move closer to answering the decades-old question of what controls the switching on and off of genes that carry out all of life's functions.

Link between vitamin D and MS susceptibility

Researchers have found evidence that a direct interaction between vitamin D and a common genetic variant alters the risk of developing multiple sclerosis.

Potential new herpes therapy studied

A new therapy being developed could produce another weapon for the fight against herpes. The gene-targeting approach uses a specially designed RNA enzyme to inhibit strains of the herpes simplex virus.

Green tea blocks cancer drug

Researchers have found that green tea renders a cancer drug used to treat multiple myeloma and mantle cell lymphoma completely ineffective in treating cancer.

How a deadly fungus protects itself

A recent study may help scientists develop new therapies or vaccines against infections caused by Cryptococcus neoformans.

Molecular evolution of Q fever pathogen

Scientists have uncovered genetic clues about why some strains of the pathogen Coxiella burnetii are more virulent than others.

Single gene lets bacteria jump

With the help of a squid that uses a luminescent bacterium to create a predator-fooling light organ, scientists have found that gaining a single gene is enough for the microbe to switch host animals.

Human DNA repair process recorded

A key phase in the repair process of damaged human DNA has been observed and visually recorded by a team of researchers at the University of California, Davis.

Bacterial intestinal infections questions

A new study finds swimming, having a private well or septic system, and other factors not involving food consumption were major risk factors for bacterial intestinal infections not occurring in outbreaks.

Bacteria that increase plant growth

Through work originally designed to remove contaminants from soil, scientists have identified plant-associated microbes that can improve plant growth on marginal land.
