Rapid diagnosis of severe kidney damage

How does a doctor determine whether or not an emergency-room patient has acute kidney injury? Using tests currently available in the hospital, this question is often difficult to answer. A large multicenter study by clinicians in Berlin, Germany and two hospitals in the US has now shown that a urine test for proteins excreted by a damaged kidney helps to swiftly identify high-risk patients.

Reports from trial registries are indispensable for systematic reviews

Different formats are available for reporting the results of clinical trials. In an article just published in the British Medical Journal, IQWiG employees investigated to what extent journal publications, reports posted in trial results registries, and clinical study reports submitted to regulatory authorities provide sufficient information to evaluate clinical trials.

Researchers quantify the damage of alcohol by timing and exposure during pregnancy

Prenatal exposure to alcohol is associated with a spectrum of abnormalities in the offspring. A new study has examined patterns of drinking specific to timing of exposure during pregnancy, collecting the information while the mother was still pregnant instead of after delivery.Numerous specific associations were found, the most significant ones during the second half of the first trimester of...

Revolutionary surgical technique for perforations of the eardrum

A revolutionary surgical technique for treating perforations of the tympanic membrane (eardrum) in children and adults has been developed at the Sainte-Justine University Hospital Centre, an affiliate of the University of Montreal, by Dr. Issam Saliba. The new technique, which is as effective as traditional surgery and far less expensive, can be performed in 20 minutes at an outpatient clinic...

Some breast cancer spread may be triggered by a protein, study shows

Cancers rarely are deadly unless they evolve the ability to grow beyond the tissues in which they first arise. Normally, cells -- even early-stage tumor cells -- are tethered to scaffolding that helps to restrain any destructive tendencies. But scientists from the University of Helsinki, Finland, and from UCSF have identified a cleaver-wielding protein that frees some tumor cells, allowing them to...

Study provides new insights into antibiotics and pig feeds

Antibiotics in pig feed increased the number of antibiotic resistant genes in gastrointestinal microbes in pigs, according to a study conducted by Michigan State University and the US Department of Agriculture's Agricultural Research Service. Published in the current edition of the Proceedings of the National Academy of Sciences, the comprehensive study focused on understanding the effects of...

U of A researcher says good wingmen will fib for a friend

It could be called the wingman theory or the Barney Stinson principle (after the character played by Neil Patrick Harris on hit TV show "How I Met Your Mother"). A University of Alberta researcher says that -- like Barney, who spends much of his time trying to find his single friend a mate -- people are generally willing to help a friend protect or enhance his reputation or help him otherwise save...

Vitamin D could help combat the effects of aging in eyes

Researchers funded by the Biotechnology and Biological Sciences Research Council have found that vitamin D reduces the effects of aging in mouse eyes and improves the vision of older mice significantly. The researchers hope that this might mean that vitamin D supplements could provide a simple and effective way to combat age-related eye diseases, such as macular degeneration, in people.

Wood-burning stoves - harmful or safe?

Wood-burning stoves are a popular source of heating in many countries. However in recent years there has been much debate about the potential negative health effects associated with wood smoke. A Norwegian researcher has studied the influence of combustion conditions on the emissions and their health effects.

Engineering team completes ambitious Antarctic expedition in the 'deep-field'

A team of four British engineers has returned to the UK after completing a grueling journey to one of the most remote and hostile locations on the planet to put in place equipment and supplies for an ambitious project later this year. Enduring temperatures of minus 35 C the Subglacial Lake Ellsworth "Advance Party" has successfully paved the way to explore an ancient lake buried beneath 3 km of...

AP - A Russian space probe designed to boost the nation's pride on a bold mission to a moon of Mars has come down in flames, showering fragments into the south Pacific west of Chile's coast, officials...

Science Weekly podcast: Playing God with nature

Alok Jha meets Dr Adam Rutherford to discuss his BBC Horizon documentary Playing God, which explores the exciting industrial potential and worrying moral dilemmas posed by synthetic biology. This new field's radical aim is "to break down nature into spare parts so that we can rebuild it however we please". Alok is joined in the studio by Observer science editor Robin McKie to rake over some of...
