Methylene blue in combo with new malaria drugs curbs the spread of malaria parasites

New combinations of agents based on the oldest synthetic malaria drug, the methylene blue stain, can curb the spread of malaria parasites and make a significant contribution to the long-term eradication called for by the international "Roll Back Malaria Initiative."

Twins born after fertility treatment have a higher risk of problems at birth and in the first three years of life

Twins born as a result of assisted reproductive technology (ART) are more likely to be admitted to neonatal intensive care and to be hospitalised in their first three years of life than spontaneously conceived twins, according to new research published online today (Wednesday 20 May) in Europe’s leading reproductive medicine journal Human Reproduction.

Computer simulation captures immune response to flu

Researchers have successfully tested first the first time a computer simulation of major portions of the body's immune reaction to influenza type A, with implications for treatment design and preparation ahead of future pandemics, according to work accepted for publication, and posted online, by the Journal of Virology.

Late motherhood boosts family lifespan

Women who have babies naturally in their 40s or 50s tend to live longer than other women. Now, a new study shows their brothers also live longer, but the brothers' wives do not, suggesting the same genes prolong lifespan and female fertility, and may be more important than social and environmental factors.

Drugs needed to preserve eggs for reproduction need to be given in stages

Cryoprotectants needed to preserve eggs for reproduction need to be given in stages, albeit rapid ones, say scientists who have developed a mathematical model that predicts optimal time for loading and unloading these drugs.

Scientists challenge current views on how genes are controlled in mammals

Scientists at the Omics Science Center (OSC) of the RIKEN Yokohama Institute in Japan - along with researchers from McGill University and other institutions worldwide - are challenging current notions of how genes are controlled in mammals.

Move over, Y chromosome - it's time X got some attention

In the first evolutionary study of the chromosome associated with being female, University of California, Berkeley, biologist Doris Bachtrog and her colleagues show that the history of the X chromosome is every bit as interesting as the much-studied, male-determining Y chromosome, and offers important clues to the origins and benefits of sexual reproduction.

Discovery of a new target for novel HIV treatment strategy

The AIDS-causing HIV specifically counteracts the mechanisms of human cells that protect these against viral infections - a special viral protein marks protective cellular proteins for their rapid destruction and thus diminishes the cell's supply.

Rural AIDS and HIV expert comments on media campaign

A recent study revealed that the public's concern about the HIV/AIDS problem in the United States has lessened: In 1995, 44 percent of people surveyed considered HIV/AIDS the most urgent health problem, but only 5 percent of study participants reported feeling this way today, said William L. Yarber, senior director of the Rural Center for AIDS/STD Prevention at Indiana University.

Gene scan shows body's sleep cycle influences numerous physical functions

The pineal gland - integral to setting the body's sleep and wake cycles - may be involved in a broad range of bodily functions, according to a study by researchers at the National Institutes of Health and other institutions.

Single embryo transfer is the cheapest and most effective strategy for assisted reproduction

Transferring single embryos to women's wombs over several assisted reproduction cycles that use both fresh and frozen embryos is more effective and cheaper than transferring two or more embryos at one time, according to data from the world's longest running series of patients who choose to have only one embryo implanted per cycle - elective single embryo transfer (eSET).

Clotrimazole drug used to treat skin conditions is a marine pollutant

Clotrimazole is a common ingredient in over-the-counter skin creams. Recent results from the University of Gothenburg, Sweden, now show that it is associated with major environmental risks. "The pharmaceuticals and chemicals in everyday use form a mixture in the ocean that has a direct impact on the growth and reproduction of organisms", says scientist Tobias Porsbring.
