Researchers develop computational model to accurately simulate complex twists of RNA

A computational model developed by researchers at Rensselaer Polytechnic Institute is the first to accurately simulate the complex twists of a short sequence of RNA as it folds into a critical hairpin structure known as a "tetraloop."

Scientists develop antibiotic whose activity can be controlled using light

Scientists at the University of Groningen have developed an antibiotic whose activity can be controlled using light. It is possible to 'switch on' the substance immediately before use, after which it will slowly lose its activity.

Study evaluates effectiveness of new meningitis serogroup A vaccine in sub-Saharan Africa

Evaluation of the effectiveness of a mass vaccination campaign with a new meningitis serogroup A vaccine, PsA-TT, in sub-Saharan Africa found that it had a dramatic impact on cases of serogroup meningitis and on carriage of the disease-causing bacteria in the throat, according to new research published in The Lancet.

Funding for antimicrobial resistance research projects in the UK unacceptably small, say researchers

Study of funding awarded to antimicrobial resistance research projects in the UK calls for political leadership and sustained and targeted spending.

Domestic animals less likely to be major source of antibiotic resistant Salmonella in humans

A new study has shown that, contrary to popular belief, local domestic animals are unlikely to be the major source of antibiotic resistant Salmonella in humans. The result comes from a detailed study of DNA from more than 370 Salmonella samples collected over a 22-year period.

Researchers develop new ways of preventing septic shock

The body's immune system is set up much like a home security system; it has sensors on the outside of cells that act like motion detectors — floodlights — that click on when there's an intruder rustling in the bushes, bacteria that seem suspect.

Microbes living in unexpected environments can generate highly toxic methylmercury

Microbes that live in rice paddies, northern peat bogs and other previously unexpected environments are among the bacteria that can generate highly toxic methylmercury, researchers at Oak Ridge National Laboratory and the Smithsonian Environmental Research Center have learned.

Research: New pathway plays role in fighting gut infection

The researchers found virulent E. coli bacteria blocked a pathway that would normally protect the gut from infection. These infections are particularly serious in young children and can result in diarrhoea and other complications such as kidney damage.

Scientists discover that copper alloys shut down highly infectious norovirus

Scientists from the University of Southampton have discovered that copper and copper alloys rapidly destroy norovirus - the highly-infectious sickness bug.

Better ways to combat mosquitoes

In an advance toward providing mosquito-plagued people, pets and livestock with an invisibility cloak against these blood-sucking insects, scientists today described discovery of substances that occur naturally on human skin and block mosquitoes’ ability to smell and target their victims.

Three rapid diagnostic tests could be used to diagnose drug resistance in TB

Results of a new study suggest that three new diagnostic tests could each be used to successfully diagnose drug resistance in tuberculosis (TB) patients in a quarter of the time taken by the current method.

Artificial nose: New device to diagnose blood infections and finger specific microbe

Disease-causing bacteria stink - literally - and the odor released by some of the nastiest microbes has become the basis for a faster and simpler new way to diagnose blood infections and finger the specific microbe, scientists reported here today at the 246th National Meeting & Exposition of the American Chemical Society (ACS), the world's largest scientific society.

PaxVax commences phase 3 clinical trial for single-dose oral cholera vaccine candidate

PaxVax Inc, which develops and commercializes innovative vaccines against infectious diseases in a socially responsible manner, today announced that it has commenced its Phase 3 clinical trial program for its single-dose oral cholera vaccine candidate, PXVX0200 (also known as CVD 103-HgR). Approximately 3,000 participants will be enrolled in this pivotal program, which is comprised of cholera challenge, safety, and immunogenicity studies.

Researchers find safety mechanism in immune system in people with autoimmune diseases

Monash University researchers have found an important safety mechanism in the immune system that may malfunction in people with autoimmune diseases, such as Multiple Sclerosis, potentially paving the way for innovative treatments.

Scientists reveal structure of protein essential for triggering necroptosis

Scientists in Melbourne, Australia, have revealed the structure of a protein that is essential for triggering a form of programmed cell death called necroptosis, making possible the development of new drugs to treat chronic inflammatory diseases such as Crohn's disease and rheumatoid arthritis.

Disease Twofer: Parkin Problem Leads To Parkinson’S And Impairs Response To TB

University of California, San Francisco researchers report that a key protein associated with Parkinson's disease also plays a major role in the destruction of the bacteria that cause tuberculosis.

Researchers explore seas and oceans to discover novel antibiotics and other medical compounds

The life that inhabits the world's oceans has almost infinite variety. It remains an untapped source of diversity. "The oceans can be deep or shallow, they can be more or less tidal, and they can include unique environments such as volcanic vents," says Brian McNeil ofStrathclyde University in Scotland, UK.

Research into 'personalised' medicine is being led by Greenwich team

Research into 'personalised' medicine is being led by a University of Greenwich team. Currently, many medicines which are prescribed to patients either do not work properly or have some significant side effects. The aim of personalised medicine, sometimes called 'precision' medicine, is to ensure that the most appropriate medicine is given to each patient and that the medicine is both effective and safe.

High-income and better hygiene countries exhibit much higher rates of Alzheimer's

New research has found a "very significant" relationship between a nation's wealth and hygiene and the Alzheimer's "burden" on its population. High-income, highly industrialised countries with large urban areas and better hygiene exhibit much higher rates of Alzheimer's.

Parkin protein plays key role in destruction of bacteria that cause tuberculosis

A protein at the center of Parkinson's disease research now also has been found to play a key role in causing the destruction of bacteria that cause tuberculosis, according to scientists led by UC San Francisco microbiologist and tuberculosis expert Jeffery Cox, PhD.
