Anti-diabetic drug springs new hope for tuberculosis patients

Singapore, Date - A more effective treatment for tuberculosis (TB) could soon be available as scientists have discovered that Metformin (MET), a drug for treating diabetes, can also be used to boost the efficacy of TB medication without inducing drug resistance.

This discovery was made by a team of international scientists led by the Singapore Immunology Network (SIgN), a research institute under the Agency for Science, Technology and Research (A*STAR), Singapore.

Asteroid that wiped out dinosaurs may have nearly knocked off mammals, too

The extinction of the dinosaurs 66 million years ago is thought to have paved the way for mammals to dominate, but a new study shows that many mammals died off alongside the dinosaurs.

Metatherian mammals--the extinct relatives of living marsupials ("mammals with pouches", such as opossums) thrived in the shadow of the dinosaurs during the Cretaceous period. The new study, by an international team of experts on mammal evolution and mass extinctions, shows that these once-abundant mammals nearly followed the dinosaurs into oblivion.

Regulation of maternal miRNAs in early embryos revealed

The Center for RNA Research at the Institute for Basic Science (IBS) has succeeded in revealing, for the first time, the mechanism of how miRNAs, which control gene expression, are regulated in the early embryonic stage.

Hugs help protect against stress and infection, say Carnegie Mellon researchers

PITTSBURGH--Instead of an apple, could a hug-a-day keep the doctor away? According to new research from Carnegie Mellon University, that may not be that far-fetched of an idea.

Combining social media and behavioral psychology could lead to more HIV testing

Social media such as Twitter and Facebook can be valuable in the fight against HIV in the United States, where research has demonstrated they can prompt high-risk populations to request at-home testing kits for the virus that causes AIDS, suggesting a way to potentially boost testing rates.

Growing shortage of stroke specialists seen

MAYWOOD, Ill. - Although stroke is the No. 4 cause of death and a leading cause of disability in the United States, there's an increasing shortage of neurologists who specialize in stroke care.

In the December issue of the journal Stroke, two prominent neurologists propose a bold program to increase the number of stroke specialists. Their proposals include encouraging more young physicians to specialize in stroke, increasing stroke specialists' pay and opening the subspecialty to physicians who are not neurologists.

Predicting antibiotic resistance

Treating bacterial infections with antibiotics is becoming increasingly difficult as bacteria develop resistance not only to the antibiotics being used against them, but also to ones they have never encountered before. By analyzing genetic and phenotypic changes in antibiotic-resistant strains of E. coli, researchers at the RIKEN Quantitative Biology Center (QBiC) in Japan have revealed a common set of features that appear to be responsible for the development of resistance to several types of antibiotics.

Unraveling the light of fireflies

Fireflies used rapid light flashes to communicate. This "bioluminescence" is an intriguing phenomenon that has many potential applications, from drug testing and monitoring water contamination, and even lighting up streets using glow-in-dark trees and plants. Fireflies emit light when a compound called luciferin breaks down. We know that this reaction needs oxygen, but what we don't know is how fireflies actually supply oxygen to their light-emitting cells.

Combining images and genetic data proves gene loss behind aggressive ovarian cancers

Cancer Research UK scientists have shown that loss of a gene called PTEN triggers some cases of an aggressive form of ovarian cancer, called high-grade serous ovarian cancer, according to a study published in Genome Biology today (Wednesday)*.

In a revolutionary approach the researchers from the Cancer Research UK Cambridge Institute made the discovery by combining images from cancer samples with genetic data. They proved conclusively that loss of PTEN was commonly found only in the cancerous cells and not the 'normal' cells that help make up the tumour mass.

Herd mentality: Are we programmed to make bad decisions?

A natural desire to be part of the 'in crowd' could damage our ability to make the right decisions, a new study has shown.

Research led by the University of Exeter has shown that individuals have evolved to be overly influenced by their neighbours, rather than rely on their own instinct. As a result, groups become less responsive to changes in their natural environment.

Nationwide project paves way for clinical genetic diagnosis

The first nationwide project to genetically diagnose rare diseases will pave the way for translating advances in genomics into patient care in the NHS. Deciphering Developmental Disorders (DDD), a collaboration between the Wellcome Trust Sanger Institute, the UK Department of Health and regional genetics services, is working with 12,000 families to diagnose their child's developmental disorder, demonstrating the feasibility and value of introducing large-scale sequencing diagnostics into health care.

BJOG release: New study outlines research priorities to improve the care of women with FGM

Further evidence on how to improve the care of women living with Female Genital Mutilation (FGM) is urgently needed, suggests a new study, published today (17 December) in BJOG: An International Journal of Obstetrics and Gynaecology (BJOG).

FGM comprises all procedures involving partial or total removal of the external genitalia for non-therapeutic reasons. It violates the human rights of women and girls, has no health benefits and can have significant, negative, psychological and health outcomes.

Research shows Jaws didn't kill his cousin

New research suggests our jawed ancestors weren't responsible for the demise of their jawless cousins as had been assumed. Instead Dr Robert Sansom from The University of Manchester believes rising sea levels are more likely to blame. His research has been published in the journal Proceedings of the Royal Society B.

Is a Nintendo a safe Christmas present?

Following reports of Nintendo related injuries and other problems, ranging from mild to life threatening, a team of Dutch researchers decided to gather all reported cases of Nintendo related problems to see whether a Nintendo is safe to give as a Christmas present

They searched two large medical databases and found 38 relevant articles. Injuries and problems ranged from neurological and psychological to surgical. They report their findings in The Christmas issue of The BMJ.

Healthy eaters: Ignore glycemic index

Good news for people who are already following a diet rich in fruits, vegetables and whole grains, and low in sweets: New research suggests these heart-healthy eaters don't need to worry about choosing low glycemic index foods to lower the risk of diabetes and heart disease. Though the study was not designed to test the effects of low glycemic index foods on weight control, its lead researchers looked at studies that did focus on weight and found no clear proof of a benefit.
