Key enzyme unlocked using 'cool' method

A team of scientists - using a new cooling method they created - has uncovered the inner workings of a key iron-containing enzyme, a discovery that could help researchers develop new medicines or understand how enzymes repair DNA.

Flightless mosquitoes fight dengue fever

A new strain of mosquitoes in which females cannot fly may help curb the transmission of dengue fever, according to UC Irvine and British scientists.

Gene regulation: Can we stomach it?

Using a newly developed sequencing technique, the researchers discovered 60 small ribonucleic acids in the genome of the Helicobacter pylori human pathogen.

Facing the corn nematode problem

Nematodes can cause above-ground symptoms similar to those caused by almost any stress and can intensify expression of specific symptoms due to nutrient deficiency, herbicide injury and other causes.

GE Healthcare Launches Biacore 4000

GE Healthcare is launching Biacore 4000, a powerful solution for large-scale, label-free molecular interaction analysis in drug discovery, from early screening to characterisation.

The Seward Stomacher 80 microBiomaster

At Analytica 2010 in Munich, Germany, Seward Limited will be demonstrating its small tissue processing solutions in Hall B2, Stand 130.

How the cholera bacteria becomes infectious

In a new study, researchers describe the structure of a protein called ToxT that controls the virulent nature of Vibrio cholerae, the bacteria that causes cholera.

Unique family of anti-cancer compounds

Scientists have streamlined the process for synthesising a family of compounds with the potential to kill cancer and other diseased cells, and have found that they represent a unique category of anti-cancer agents.

Limiting the spread of antibiotics

Research by scientists at the University of Missouri Center for Agroforestry suggests that buffer strips of grasses and other plants can...

Proteins cover blood type blind spot

A set of proteins found in our intestines can recognise and kill bacteria that have human blood type molecules on their surfaces, scientists have discovered.

The almond tree's secret weapon

Researchers speculate that the toxin called amygdalin that is found in almond tree nectar is in fact an evolutionary development intended to give that tree an advantage over others in its surroundings.

Advance in imaging of cell death

A new paper describes important progress in using a synthetic probe to target dead and dying cells in mammary and prostate tumors in living animals.

Fighting deadly staph infections

Researchers have found that two antibiotics working together might be more effective in fighting pathogenic bacteria than either drug on its own.

Hope for effective Salmonella vaccine

Research from Malawi, Birmingham and Liverpool has renewed hope that an effective vaccine could be developed against nontyphoidal strains of Salmonella.

Enzyme triggers switch in glucose processing

A study investigating how a cellular enzyme affects blood glucose levels in mice provides clues to pathways that may be involved in processes including the regulation of longevity and the proliferation of tumour cells.

Prevent life-threatening bloodstream infections

Paediatric hospitals can significantly decrease the number of bloodstream infections from central venous catheters by following some low-tech rules.

Potential way to reverse cancer cell metabolism

A team of scientists has discovered molecular factors in cancer cells that boost the production of an enzyme that helps alter the cells' glucose metabolism.

Bacterial membrane-coat proteins

A group of related bacteria in the superphylum Planctomycetes-Verrucomicrobia-Chlamydiae have remained in relative obscurity ever since they were first described about a decade ago.

Understanding bacteria's thinking

Researchers show that bacteria are more capable of complex decision-making than previously known.

Genome advances peril for pests

Parasitic wasps kill pest insects, but their existence has been largely overlooked by the public - until now.
