In Africa, the spread of parasitic worms known as Loa loa is seriously hindering the efforts of health care workers to cure particular rampant diseases. Though there are drugs available to treat both river blindness and lymphatic filariasis, if they are administered to a patient who also happens to also be infected with Loa loa the consequences can be lethal. This is complicated further by the inherent difficulties in screening for the worms, but a newly developed mobile phone microscope needing only a drop of blood to automatically detect the parasite promises to make things a whole lot simpler.

Scientists at the Lawrence Berkeley National Laboratory and the University of California, Berkeley have created a hybrid system of bacteria and semiconducting nanowires that mimics photosynthesis. According to the researchers, their versatile, high-yield system can take water, sunlight and carbon dioxide and turn them into the building blocks of biodegradable plastics, pharmaceutical drugs and even biofuel.

Bedsores are more than a pain in the backside for bedridden folk, they can develop into dangerous infections and heighten the chances of a patient dying. While swollen ulcers on the skin are a pretty sure sign of their presence, by this point it is often too late for some of their effects to be reversed. But a team of researchers have developed what could function as an early warning system, a smart bandage containing flexible electronics that detects tissue damage before it becomes visible on the surface of the skin.

Studying insects in flight can be difficult. They're usually tethered in place, although this may affect the manner in which they fly. That's why scientists from the University of California, Berkeley and Singapore’s Nanyang Technological University (NTU) took a different approach – they installed an electronic backpack on giant flower beetles, allowing them to be remotely controlled while in free flight. The technology not only gave the researchers a better insight into how the insects fly, but it could also find use in areas such as search-and-rescue. Read More
A thin and flexible chameleon-like material developed by engineers at the University of California, Berkeley changes color when stretched or bent even tiny amounts. With potential applications in camouflage, structural fatigue sensors, display technologies, and more, the material's color changes reliably as it gets flexed thanks to rows of ridges that are precisely etched onto a silicon film one thousand times thinner than a human hair.

We've already seen a number of technologies developed for capturing carbon dioxide emissions from smokestacks or other sources, but many of them have a limitation – in order to reclaim the captured CO2 for disposal, a considerable amount of energy is needed. Now, however, scientists at the University of California, Berkeley have developed a new carbon-capture material that requires far less energy in order to give up its payload. Read More
3D printing looks set to become very important in architecture, but we've yet to see exactly how the future of large-scale click-and-print construction will play out. A potential step forward comes via a team of UC Berkeley researchers led by Associate Professor of Architecture Ronald Rael, who recently created a free-standing pavilion called Bloom to demonstrate the precision of their powder-based cement method of 3D-printed construction.

The growing number of biological structures being grown on chips in various laboratories around the world is rapidly replicating the entire gamut of major human organs. Now one of the most important of all – a viable functioning heart – has been added to that list by researchers at the University of California at Berkeley (UC Berkeley) who have taken adult stem cells and grown a lattice of pulsing human heart tissue on a silicon device.

Maintaining a steady blood oxygen level is critical for the body to stave off breathing problems and organ trouble. For those needing to keep a close eye on things, there's no shortage of monitoring systems and dedicated pulse oximeters available, but these can be somewhat unwieldy. Scientists at the University of California (UC) Berkeley are looking to make the process a little less cumbersome with the development of a thin, blood-oxygen sensor that can be worn much like a Band-Aid.

A new genetic therapy that helped blind mice and dogs respond to light stimulus could restore sight to people who suffer from diseases such as retinitis pigmentosa (a gradual loss of vision from periphery inwards). The therapy uses chemicals known as photoswitches, which change shape when hit with light, to open the channels that activate retinal cells. Treated mice can distinguish between steady and flashing light, while dogs with late-stage retinal degeneration also regain some sensitivity to light. Read More
