Gene against bacterial attack unravelled

A Dutch researcher from AMC Medical Centre in Amsterdam has unravelled a genetic defence mechanism against the lethal bacteria Burkholderia pseudomallei.

Discoloured buildings due to bacteria

Bacteria are also responsible for the ageing of buildings and monuments - a process known as bio deterioration, where organisms change the properties of materials through their vital activities.

Biosolids microbes pose risk to workers

A new study published in the November-December issue of Journal of Environmental Quality examines the health hazards of treated sewage sludge application to land.

Contact lenses home to pathogens

New research shows that a high percentage of contact lens cases in Tenerife are contaminated with Acanthamoeba that cannot be killed by...

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.

Bacteria helps control weight

A single molecule in the intestinal wall, activated by the waste products from gut bacteria, plays a large role in controlling whether the host animals are lean or fatty.

Turning to nature for new drugs

One of the best places to seek novel compounds for pharmaceutical drugs is within natural systems that have evolved over millions of years....

Nanotechnology boosts war on superbugs

Scientists are using a novel nanomechanical approach to investigate the workings of vancomycin, one of the few antibiotics that can be used to combat increasingly resistant infections such as MRSA.

New virus could combat malaria

A team of researchers, led by Dr. Jason Rasgon, have identified a previously unknown virus that is infectious to Anopheles gambiae. ...

Atomic resolution hints at enzyme function

An atomic-resolution view of an enzyme found only in the eye has given researchers clues about how this enzyme, essential to vision, is activated.

Protection for stressed-out bacteria

An international team of researchers is a step closer to understanding the spread of deadly diseases such as listeriosis, after observing for the first time how bacteria respond to stress.

Living nanotechnology factories

Bypassing limitations on raw materials, a researcher has managed to use cells as factories to make DNA based nanostructures inside a living cell.

Novel cell modification in cancer

A research team at Cold Spring Harbor Laboratory is clarifying a previously unappreciated way that cellular processes are disrupted in cancer.

Disinfectants may aid bacteria resistance

Low levels of biocides can make Staphylococcus aureus remove toxic chemicals from the cell even more efficiently, potentially making it resistant to some antibiotics.

Bacteria prevents some cancers

Some bacteria may help protect against the development of a type of esophageal cancer, known as adenocarcinoma, according to a new review of the medical literature.

Bacterial crisis command centre

A bacteria cell's 'crisis command centre' has been observed for the first time swinging into action to protect the cell from external stress and danger, according to new research.

Eel cells suggest electrifying possibilities

Researchers argue that artificial cells could be built that not only replicate the electrical behaviour of electric eel cells but in fact improve on them.

Some bacteria fight infection

A new study shows that the DNA of so-called "good bacteria" that normally live in the intestines may help defend the body against infection.

Gene regulation: Simple twists of fate

Using state-of-the art tools, researchers observed the shape and behaviour of individual DNA molecules bent into tight loops by Lac repressor.

TB sugar coat aids survival

Common strains of tuberculosis-causing bacteria have hijacked the human body's immune response to play tricks on cells in the lungs, scientists say.
