No wisdom in routinely pulling wisdom teeth, study says

No reliable studies exist to support removal of trouble-free impacted wisdom teeth, according to a systematic review of evidence. Despite this surprising lack of data, extraction of third molars has long been considered appropriate care in most developed countries.

“Watchful monitoring” of asymptomatic wisdom teeth may be a more appropriate strategy, suggest review authors led by Dr. Dirk Mettes of Radboud University Medical Centre Nijmegen in the Netherlands. Furthermore, they ad

Little evidence found for IVF as most effective infertility treatment

In vitro fertilization can improve pregnancy rates among couples with unexplained infertility, but there is little evidence to show whether IVF results in more live births than other treatments, according to a new review of recent studies.

Although expensive and invasive, IVF is a widely used treatment, despite potential complications, including a multiple pregnancy rate of about 25 percent.

According to the analysis by Dr. Zabeena Pandian of the University of Aberdeen,

‘Share it!’ – Watch What You Want, When You Want!

We will all soon be able to watch what we want on our televisions, when we want thanks to a project funded with the help of six million euros from the Information Society Technologies area of the EU’s Framework Programme.

Building on the communication technologies developed and improved in recent years, ‘Share it!’ developed an end-to-end system that provides seamless access to on-line, broadcast and personally stored content. It allows easy access and transfer of the content bet

Migration study finds that sweeping management changes are needed to protect Atlantic bluefin tuna

A team of marine scientists has mapped the undersea journeys of Atlantic bluefin tuna and concluded that tighter restrictions should be placed on commercial fishing to protect the feeding and breeding grounds of this top migratory predator–one of the most commercially valuable fish in the sea.

Researchers from Stanford University and the Monterey Bay Aquarium say that their new study, published in the April 28 edition of the journal Nature, offers substantial evidence that signi

Wisconsin researchers identify sleep gene

Zeroing in on the core cellular mechanisms of sleep, researchers at University of Wisconsin Medical School have identified for the first time a single gene mutation that has a powerful effect on the amount of time fruit flies sleep.

In its normal state, the Drosophila (fruit fly) gene, called Shaker, produces an ion channel that controls the flow of potassium into cells, a process that critically affects, among other things, electrical activity in neurons. A handful of recent

Children do well with shorter fast before surgery

Children facing surgery can be made more comfortable with little risk by allowing them to have certain liquids up to two hours before the operation, a new review of recent studies has found.

Like adults, children are often required to go without food or drink up to a half-day before surgery to prevent their stomach contents from being regurgitated or sucked into the lungs under general anesthesia. In the review of 43 randomized controlled trials involving 2,350 children, only one
