Revealed: How sticky egg captures sperm
Revealed: How sticky egg captures sperm
Researchers have uncovered exactly how a human egg captures an incoming sperm to begin the fertilisation process, in a new study published this week in the journal Science . The research identifies the sugar molecule that makes the outer coat of the egg 'sticky', which is vital for enabling the sperm and egg to bind together.

Modified Ectsasy holds promise as potent blood cancer treatment
Modified Ectsasy holds promise as potent blood cancer treatment
Scientists at the University of Birmingham have discovered a modified form of the drug MDMA - commonly known as Ecstasy - which has 100 times more cancer-busting properties than the popular recreational drug itself and which they hope may be able to be produced in a safe form to treat patients. Research results published online today (18 August 2011) in the journal Investigational New Drugs show significant success in 'redesigning the designer drug' for potential use as a cancer-killing agent in the treatment of leukaemia, lymphoma and myeloma.

A new function for vitamin C in Alzheimer´s
A new function for vitamin C in Alzheimer´s
Researchers at Lund University have discovered a new function for vitamin C. Treatment with vitamin C can dissolve the toxic protein aggregates that build up in the brain in Alzheimer's disease. The research findings are now being presented in the Journal of Biological Chemistry. The brains of people with Alzheimer's disease contain lumps of so-called amyloid plaques which consist of misfolded protein aggregates.

Want to keep your exercise resolutions? New research offers pointers
New research reveals factors that helped some commit to a yearlong exercise program. Photo by Edward McCauley CHAMPAIGN, lll. Sticking with an exercise routine means being able to overcome the obstacles that invariably arise. A key to success is having the confidence that you can do it, researchers report.

Study sheds light on late phase of asthma attacks
Study sheds light on late phase of asthma attacks
New research led by scientists from Imperial College London explains why around half of people with asthma experience a 'late phase' of symptoms several hours after exposure to allergens. The findings, published in the journal Thorax , could lead to better treatments for the disease. An estimated 300 million people suffer from asthma, and the prevalence is rising.

Childhood maltreatment & depression
People who have experienced maltreatment as children are twice as likely to develop both multiple and long-lasting depressive episodes as those without a history of childhood maltreatment, according to a new study. The research, led by a team at King's College London Institute of Psychiatry, also found that maltreated individuals are more likely to respond poorly to pharmacological and psychological treatment for depression.

UW Medicine study finds caffeine guards against certain ultraviolet-induced skin cancers at molecular level
UW Medicine study finds caffeine guards against certain ultraviolet-induced skin cancers at molecular level
Caffeine guards against certain skin cancers at the molecular level, according to a study appearing online August 15, 2011, in the Proceedings of the National Academy of Sciences (PNAS) that explains how the process likely works. Senior author Paul Nghiem , associate professor of dermatology and pathology at the University of Washington School of Medicine, and colleagues genetically modified mice so the rodents would have diminished function of a protein enzyme in their skin known as ATR.

New treatment option for advanced prostate cancer
Prostate cancer that has become resistant to hormone treatment and that does not respond to radiation or chemotherapy requires new methods of treatment. By attacking stem cell-like cells in prostate cancer, researchers at Lund University are working on a project to develop a new treatment option.

Number of genes associated with MS doubles
Number of genes associated with MS doubles
Scientists have identified 29 new genetic variants linked to multiple sclerosis, providing key insights into the biology of a very debilitating neurological disease. Many of the genes implicated in the study are relevant to the immune system, shedding light onto the immunological pathways that underlie the development of multiple sclerosis.

Research on TB tests prompts first-ever WHO negative policy
McGill / RI MUHC-led teams publish on inaccuracy and poor cost-effectiveness of widely used TB antibody tests No policy has ever recommended serological (antibody) tests to detect active tuberculosis (TB) yet dozens of these blood tests are currently marketed and sold in developing countries where regulation is weak or non-existent.

TB antibody detection tests fail to diagnose tuberculosis accurately
TB antibody detection tests fail to diagnose tuberculosis accurately
Commercially available serological tests fail to accurately diagnose active tuberculosis (TB) and they are not as cost effective as other recommended TB tests, according to two papers published Aug. 9 in the Public Library of Science (PLoS) Medicine. The researchers note that these tests often provide misleading results that may harm patients.

Genetic link to human intelligence
Scientists have provided the first direct biological evidence for a genetic contribution to people's intelligence. Previous studies on twins and adopted people suggested that there is a substantial genetic contribution to thinking skills, but this new study - published in the journal Molecular Psychiatry - is the first to find a genetic contribution by testing people's DNA for genetic variations.

Simple physics predicts how the gut forms
Simple physics predicts how the gut forms
Growing embryos face a tight squeeze when it's time to pack internal organs. A new study published in Nature Aug. 4 shows how simple mechanical forces between neighboring types of tissue help organs take shape and grow. The work is among the first to uncover how an embryo develops from groups of cells into distinctly shaped organs.

A natural food preservative that kills food-borne bacteria
Researchers have discovered and received a patent for a naturally occurring lantibiotic — a peptide produced by a harmless bacteria — that could be added to food to kill harmful bacteria like salmonella, E. coli and listeria. The U of M lantibiotic is the first natural preservative found to kill gram-negative bacteria, typically the harmful kind.

Eating disorders and fertility research
Eating disorders and fertility research
Eating disorders such as anorexia and bulimia are associated with fertility problems and negative attitudes to pregnancy, according to a study from King's scientists. The research also revealed high rates of unplanned pregnancies in women with a history of anorexia, suggesting they may be underestimating their chances of conceiving.

New method for early detection of Alzheimer's disease
New method for early detection of Alzheimer’s disease
Scientists at The University of Manchester have discovered that measurements of brain activity could be used to predict Alzheimer's disease in people with mild memory problems. It's hoped the study, which was part-funded by Alzheimer's Research UK, will help improve clinical trials to find new treatments for the disease.

New research challenges our understanding of cell communication
New research challenges our understanding of cell communication
Cells often communicate with one another using pulsatile signals, where information is conveyed in pulse frequency as well as amplitude. This raises the question of how cells decode pulsatile signals, a question that lies at the core of our understanding of how the brain controls reproduction.

Researchers map minority microbes in the colon
Researchers map minority microbes in the colon
CHAMPAIGN, lll. They make up less than one-hundredth of 1 percent of the microbes that live in the colon, but the bacteria and archaea that sop up hydrogen in the gut are fundamental to colon health. In a new study, researchers take a first look at these "hydrogenotrophic" microbes, mapping where they live and how abundant they are in different parts of the lower intestine.

New method for the diagnosis of cancer
New method for the diagnosis of cancer
Researchers have developed a new breast cancer diagnostic method, and is now carrying out first tests on non-preserved human tissue. This new method should be able to reveal structures that cannot be seen using conventional mammography. Standard procedures only determine the extent to which X-rays are attenuated by various tissue structures.
