Birth control shot may impair a person's memory

The birth control shot Depo Provera offers a convenient alternative for women who don't want to remember to take a daily pill. Ironically, research from Arizona State University has shown the shot actually may impair a person's memory.

Protective response to starvation may promote heart failure

A protective response to starvation may promote heart failure, according to a study just published in Cell Metabolism. Two proteins that team up to conserve energy when food is scarce also limit energy production in the heart—a situation that can prove fatal when the heart is stressed and in need of an energy boost.

Massive clotting can destroy placenta and cause miscarriages

Researchers at St. Michael's Hospital have identified a potential new cause for unexplained miscarriages in mice.

First study to show how H. pylori toxin can spur apoptosis

Researchers report they have figured out how the cancer-causing bacterium Helicobacter pylori attacks a cell's energy infrastructure, sparking a series of events in the cell that ultimately lead it to self-destruct.

Researchers develop new 3D bone marrow culture systems

Stromal cells, as distinct from hematopoietic cells, are an essential component of the bone marrow microenvironment and are necessary for the long-term maintenance of hematopoietic stem cells (HSCs) in vitro.

Scientists discover additional Alzheimer's proteins in the tangles

Scientists from the National Institutes of Health in the United States have made an important discovery that should forever change the scope and direction of Alzheimer's research. Specifically, they have discovered that the protein tangles which are a hallmark of the disease involve at least three different proteins rather than just one.

$Adiponectin linked to osteoporosis and increased risk of fractures$

Adiponectin linked to osteoporosis and increased risk of fractures

While obesity is a well-known cause of cardiovascular disease, research from the Sahlgrenska Academy at the University of Gothenburg, Sweden, has now revealed that the body's obesity hormones - adiponectin - are also linked to osteoporosis and an increased risk of fractures.

Potential drug therapy for Hutchinson Gilford Progeria Syndrome

Researchers have identified a potential drug therapy for a premature ageing disease that affects children causing them to age up to eight times as fast as the usual rate.

Glyphosine can prevent development of type 1 diabetes

Researchers at the University of Colorado School of Medicine have found a specific molecule that can prevent the development of type 1 diabetes in mice and has a similar effect on human cells from diabetic patients.

New protein microarray technology could eradicate malaria

A new research technology is revealing how humans develop immunity to malaria, and could assist programs aimed at eradicating this parasitic disease.

Interleukin Genetics commences two new PST test clinical studies in China

Interleukin Genetics, Inc. announced today that the Company has initiated two clinical studies to demonstrate the utility of its new PST genetic test in the ethnic Chinese population. The programs are being conducted in collaboration with Professor Chi-Cheng Tsai of Kaohsiung Medical University and Professor Dong Chen at Shanghai Stomatological Disease Center.

Hippocampus supports both recollection and familiarity memories

Human memory has historically defied precise scientific description, its biological functions broadly but imperfectly defined in psychological terms. In a pair of papers published in the November 2 issue of The Journal of Neuroscience, researchers at the University of California, San Diego report a new methodology that more deeply parses how and where certain types of memories are processed in the brain, and challenges earlier assumptions about the role of the hippocampus.

Drinking cherry juice improves quality and duration of sleep

Drinking cherry juice significantly improves both the quality and duration of sleep, according to new findings from Northumbria University.

GSK, Alnylam collaborate to apply VaxiRNA technology for influenza vaccine production

Alnylam Pharmaceuticals, Inc., a leading RNAi therapeutics company, announced today it has formed a collaboration with GlaxoSmithKline (GSK) focused on Alnylam's VaxiRNATM technology for certain GSK vaccine products, including influenza. VaxiRNA is a new RNAi technology for the enhanced production of viruses used in the manufacture of vaccine products. GSK, a leading vaccine manufacturer, is the first company to form a collaboration accessing this new platform.

GM mosquitoes show promise in tackling insect-borne diseases, study shows; some concerned over possible unintended consequences

"Genetically modified mosquitoes could prove effective in tackling dengue fever and other insect-borne diseases," according to the results of a study by a U.K.-based scientific team published in the journal Nature Biotechnology on Sunday, BBC News reports.

Restoration of dopamine levels could potentially prevent drug abuse

Portuguese researchers have discovered that rats exposed before birth to glucocorticoids not only show several brain abnormalities similar to those found in addicts, but become themselves susceptible to addiction (the glucorticoids, which are stress hormones, were used to mimic pre-natal stress).

Scientists identify genetic mutation that causes rare childhood disease

An international collaboration of scientists, including researchers at the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), a part of the National Institutes of Health, has identified a genetic mutation that causes a rare childhood disease characterized predominantly by inflammation and fat loss.

Peroxiredoxin enzyme holds key to ageing process

By consuming fewer calories, ageing can be slowed down and the development of age-related diseases such as cancer and type 2 diabetes can be delayed. The earlier calorie intake is reduced, the greater the effect. Researchers at the University of Gothenburg have now identified one of the enzymes that hold the key to the ageing process.

Knife-edge scanning microscopy rapidly maps new blood vessels in organs

Like normal tissue, tumors thrive on nutrients carried to them by the blood stream. The rapid growth of new blood vessels is a hallmark of cancer, and studies have shown that preventing blood vessel growth can keep tumors from growing, too. To better understand the relationship between cancer and the vascular system, researchers would like to make detailed maps of the complete network of blood vessels in organs. Unfortunately, the current mapping process is time-consuming: using conventional methods, mapping a one-centimeter block of tissue can take months.

Ultra-sensitive techniques for early detection of breast cancer

A team of scientists at Tufts University will develop ultra-sensitive techniques at the single-molecule and single-cell levels designed to detect breast cancer earlier, and treat it with greater precision, through a $6.6 million Innovator Award from the Department of Defense Breast Cancer Research Program made to Tufts chemist David R. Walt, Ph.D.
