It seems there's almost nothing computers can't simulate these days: Now, a new computer program simulates human birth using 3D virtual reality.
The simulator is the first of its kind to take into account factors such as the shape of the mother's body, and the shape and position of the baby. It could help doctors and midwives prepare for unusual or dangerous births, according to the researchers in England who developed it.

A novel malaria vaccine developed at Oxford University has shown promising results in the first clinical trial to test whether it can protect people against the mosquito-borne disease. The trial was carried out in Oxford by researchers led by Professor Adrian Hill of the Jenner Institute at Oxford University, along with colleagues from the biotechnology company Okairos. Some of the adult volunteers were completely protected against malaria in this initial study of the vaccine’s efficacy.
El Informe sobre Desarrollo Humano (IDH) fue presentado por primera vez en 1990, con el objetivo único de situar nuevamente a las personas en el centro del proceso de desarrollo en términos de debates económicos, formulación de políticas y promoción.
X-rays transformed medicine a century ago by providing a noninvasive way to detect internal structures in the body. Still, they have limitations: X-rays cannot image the body’s soft tissues, except with the use of contrast-enhancing agents that must be swallowed or injected, and their resolution is limited.
But a new approach developed by researchers at MIT and Massachusetts General Hospital (MGH) could dramatically change that, enabling the most detailed images ever — including clear views of soft tissue without any need for contrast agents.
The new technology “could make X-rays ubiquitous, because of its higher resolution, the fact that the dose would be smaller and the hardware smaller, cheaper, and more capable than current X-rays,” says Luis Velásquez-García, a principal research scientist at MIT’s Microsystems Technology Laboratories and senior author of the PowerMEMS paper.
Velásquez-García says that while conventional X-ray systems show little or no structure in most soft tissues — including all of the body’s major organ systems — the new system would show these in great detail. A test the team performed with an eye from a cadaver using X-rays from a particle accelerator clearly shows “all the structures, the lens and the cornea,” he says. “In time we are confident our system will be able to achieve such resolution with a far simpler and cheaper device.”
The key is to produce coherent beams of X-rays from an array of micron-sized point sources, instead of a spread from a single, large point as in conventional systems, Velásquez-García explains. The team’s approach includes developing hardware that is an innovative application of batch microfabrication processes used to make microchips for computers and electronic devices.

This year, Sony filed a patent for what might seem to be a silly idea for a wearable device with built-in vital sign monitoring — a “SmartWig”.
The SmartWig is meant to cover ”at least a part of a head of a user” and the patent offers use cases for the wig that span from general health tracker to a presentation aid.
Because the technology is on the head, Sony plans for it to monitor health factors such as brain waves, temperature, pulse, blood pressure, sweat. The company also wants the SmartWig to track environmental information like image, sound, humidity, temperature, and density of CO2. Sony specifies that the wig could also help blind people with navigating and understanding when there is an obstacle behind them.
A camera in the wig, Sony says, could be a way for users to communicate with each other and a laser pointer within the wig could help users present information before audiences.
Unlike other head-worn trackers that MobiHealthNews has covered in the past, Sony emphasizes the fact that the SmartWig’s sensors will be hidden, making the device more appealing to users. Another advantage of the SmartWig, Sony says, is that ”users instinctively protect their heads more than other body parts”, which the company believes is “advantageous” because it reduces the risk of the device being damaged during use. Sony also plans to potentially integrate the wig with other computing devices, such as “computer glasses,” by which Sony is probably referring to products like Google Glass.
Many mobile health device makers have tried to appeal to the potential user’s fashion sense, and naturally, Sony’s SmartWig would too:
“The wig itself may have a fancy or funny appearance, but may also have an inconspicuous appearance so that other people in the surrounding of the user may not even take notice of the wearable computing device,” the patent says. “In contrast to wearable computing devices known from the art, the wearable computing device proposed in this disclosure thus has the potential to become very popular and commonly used. The proposed device could even be used as a kind of combined technically intelligent item and fashion item at the same time.”
Maybe it goes without saying, but big companies, like Sony, are always filing patents for what seem to be weird product ideas and most never come to market.
