Mother Finch Controls Baby’s Sex to Increase Survival Odds

Most mothers-to-be must simply hope for healthy offspring. But female house finches tip the odds in their babies’ favor by pre-determining their gender, a new study suggests. According to a report published in the current issue of the journal Science, enterprising mother house finches adjust the sex and growth of their offspring to account for the order in which the eggs are laid, thereby reducing the mortality of their sons and daughters by 10 to 20 percent.

Over 40,000 Lives Lost Worldwide Every Year

The ‘humble’ aspirin, which has been known for at least a decade to prevent heart attacks and strokes in thousands of people at high risk of cardiovascular disease, is still massively underused, according to new research published today (Fri Jan 11) in the British Medical Journal.

Previous studies show that aspirin (and other antiplatelet drugs) could prevent around 100,000 premature deaths worldwide every year, including at least 7,000 per year in Britain alone. As a result, aspirin is almo

Giving patients more information reduces antibiotic use

General practitioners prescribe antibiotics to three-quarters of UK adults with acute bronchitis each year, even though there is little evidence to justify it. Yet, a study in this week’s BMJ finds that reassuring these patients and sharing the uncertainty about prescribing in an information leaflet reduces antibiotic use.

In this study, over 250 adults with acute bronchitis were divided into two groups. In group A, 212 patients were judged by their general practitioner not to need antibioti

Depression As A Cause Of Stroke

Middle-aged men are over three times more likely to suffer a fatal stroke if they suffer from depression, according to latest research published in `Stroke`.
The results are taken from an on-going study, funded by The Stroke Association, of 2,124 men aged between 49-64 years old, living in Caerphilly, South Wales. The men were studied for over 14 years after an initial medical check up and a history of mood, smoking, blood pressure levels and other risk factors were collected.

Abstaining Smokers Fare Better After Surgery

Authors of a study in this week’s issue of THE LANCET conclude that smokers should avoid smoking for around two months before surgery to reduce the risk of cardiovascular or wound-healing complications.

Smokers are at higher risk of cardiopulmonary and wound-related postoperative complications than non-smokers due to the adverse effects of tobacco smoke on the body’s cardiopulmonary function and immune system. Ann Moller and colleagues from Bispebjerg University Hospital, Copenhagen, Denmar

Natural Cataclysms Predict Glaciations

Not only geologists are interested in giant canyons of Kursk Magnetic Anomaly, but also soil scientists. There is very convenient place to watch old soils, which earlier were on the surface. As the canyons grew wider, details of ancient landscapes and their changes appear. While studying one of those canyons, Svetlana Sycheva from the Institute of Geography Russian Academy of Sciences has found that earlier there was a system of large ravines, now buried under a thick layer of sediments.
