Molecule-making machine simplifies complex chemistry Posted: 12 Mar 2015 11:29 AM PDT A new molecule-making machine could do for chemistry what 3-D printing did for engineering: Make it fast, flexible and accessible to anyone. Chemists built the machine to assemble complex small molecules at the click of a mouse, like a 3-D printer at the molecular level. The automated process has the potential to greatly speed up and enable new drug development and other technologies that rely on small molecules.

High-tech gas sensing capsules for better gut health Posted: 12 Mar 2015 10:07 AM PDT High-tech gas sensing capsules that can send data from inside the gut direct to a mobile phone have been developed by scientists, opening new possibilities for diagnosis, treatment and health analysis.

Database on healthy immune system developed Posted: 12 Mar 2015 09:36 AM PDT An extensive database identifying immune traits, such as how immune cell function is regulated at the genetic level in healthy people, has been developed by researchers. While many genetic risk factors have been linked to various diseases, including autoimmune disorders, how a genetic change causes susceptibility to a disease is not always clear. By studying healthy people, researchers have created a reference resource for other scientists.

In pursuit of the perfectly animated cloud of smoke: Simulations more realistic than ever Posted: 12 Mar 2015 07:07 AM PDT Simulations of impressive landscapes and alien creatures have become commonplace, especially in fantasy and science fiction films. But simulations are also appearing in ever more medical and engineering applications. However, the road to a perfect illusion is complex and time-intensive. Scientists have now developed a methodology that could accelerate these calculations.

Developers neglect privacy, security in health apps Posted: 12 Mar 2015 06:22 AM PDT Telemedicine researchers have proposed a series of recommendations to programmers to improve the security of health applications on mobile devices. According to these specialists, it is a rapidly growing area, but the insecure handling of clinical and medical data can be critical for users. Health applications are enjoying a boom. There are already some 100,000 on the market on iOS (Apple) and Android platforms, generating 4.5 billion dollars’ worth (around 3.3 billion euros) of business, researchers note.

Large gains with new chip design for medical devices Posted: 12 Mar 2015 05:28 AM PDT Systems-on-a-chip for extremely critical applications would use 28 percent less energy and 48 percent less chip area while offering nine times lower hardware failure rate, if designed with the completely novel architecture. This would drastically reduce hospital costs and replacement rate of medical devices.
