For many of with impaired hearing, their hearing is so damaged that a standard hearing aid is no longer enough. A new device will improve patients' hearing and can be implanted during outpatient surgery.

Of all the transhumanist technologies coming in the near future, one stands out that both fascinates and perplexes people. It's called ectogenesis: raising a fetus outside the human body in an artificial womb.

It has the possibility to change one of the most fundamental acts that most humans experience: the way people go about having children. It also has the possibility to change the way we view the female body and the field of reproductive rights.

Naturally, it's a social and political minefield...

The most frequent philosophical issue brought up about ectogenesis is how it might change the way society views women. Will the feminine mystique be lost by such an artificial process replacing what's been long a mainstay of the female domain? My short answer is no; rather, ectogenesis could further unchain women from the home, spare them and extend the age at which women can have children.

A malaria vaccine has become the first to provide 100% protection against the disease, confounding critics and far surpassing any other experimental malaria vaccine tested. It will now be tested further in clinical trials in Africa.

The technique, which is still in experimental stages, takes advantage of a rare mutation that makes one percent of people of European descent resistant to HIV.

Using a new "genome editing" tool, researchers are hoping to be able to insert the mutation into the cells of other people - and they've already proved the basic principles work using induced pluripotent stem cells (iPSCs), Peter Aldhous reports for New Scientist.

The new genome editing technique is much more precise than tradition forms of genetic engineering, as it places a sequence of gene into a pre-designated area of the genome, rather than at random locations. By using this technique, researchers led by Yuet Kan from the University of California, San Francico, have managed to alter the genome of iPSCs, which can turn into any cell in the body. As predicted, when the scientists grew these iPSCs into white blood cells, they were resistant to HIV.

A fungus living in the soils of Nova Scotia could offer new hope in the pressing battle against drug-resistant germs that kill tens of thousands of people every year, including one considered a serious global threat.

A team of researchers led by McMaster University has discovered a fungus-derived molecule, known as AMA, which is able to disarm one of the most dangerous antibiotic-resistance genes: NDM-1 or New Delhi Metallo-beta-Lactamase-1, identified by the World Health Organization as a global public health threat.

A monster virus comes back from ancient times to wreak havoc on mankind. That may sound like a blurb from a science fiction novel, but as scientists have known for some time, it's not at all impossible. And thanks to the recent revival of a 30,000-year-old giant virus in Siberia, there's increasing concern that it might describe our future.

But before you go diving into your hermetically sealed fallout shelters, it's important to note that, at least thus far, this and every other virus we've found sleeping deep beneath the surface hasn't been of any threat to mankind. So why's everybody talking about this discovery like it's the opening of the seventh seal? In proving that dormant viruses this ancient can, in fact, be revived, we've just opened up a Pandora's box of pandemic proportions.
