The spores of the Bacillus subtilis (pictured above) have been implemented into a vaccine ...

Taking the “ouch” out of injections is a worthy endeavor, but what if they could be avoided entirely? New research conducted at Royal Holloway, University of London offers the hope of achieving just this, by using a bacterium to deliver a vaccine which can be administered via nasal spray, oral liquid, capsule, or small soluble film placed under the tongue, thus reducing the risk of spreading infectious diseases like HIV.  Read More

Gravity waves are the big ticket item of physics. Predicted by Albert Einstein in 1916 as part of his general theory of relativity, these waves could help scientists solve many mysteries about the origin of the universe – if they could detect them. In an attempt to do this, researchers at Stanford University and NASA’s Goddard Space Flight Center are developing a new atomic interferometry technique that may be sensitive enough to record gravity waves for the first time.  Read More

For many of us, pointing a device at an object and retrieving data about it has become part of our daily lives. The vast majority of our purchases will sport the ubiquitous barcode; an increasing number of printed magazine adverts, online articles and even television shows are using QR codes for access to more information; and most recently, near field communication technology is opening up new ways to interact with the world around us. A team of researchers from the Human-Computer Interaction Institute and Heinz College Center for the Future of Work Carnegie Mellon University has been looking into an alternative object tagging system called acoustic barcodes. The system takes the sound of a finger, pen or phone scraping across a series of parallel notches etched, embossed or cut into a surface or object, and converts it into a unique binary ID.  Read More

Work being conducted on the renal organoids, at the Mario Negri Institute for Pharmacologi...

While it may not be possible to grow functional human kidneys in a lab just yet, scientists at Italy’s Mario Negri Institute for Pharmacological Research have definitely come a step closer. In a paper published last week, they reported that they have created kidney-like “organoids,” that perform the same functions as kidneys when implanted in rats.  Read More

Artist's concept of a servicing satellite (Image: NASA)

Geostationary satellites cost a fortune and, despite their sophistication, they break down or eventually run out of propellant to keep them oriented. This is unfortunate when the nearest garage is back on Earth, so NASA wants to remedy this with an orbital version of roadside service. The space agency is developing a service robot that can visit ailing satellites and refuel or even repair them on the spot.  Read More

Though often associated with exposure to war, Post-Traumatic Stress Disorder (PTSD), is a severe anxiety disorder which can arise following exposure to any event which has caused psychological trauma. Those who suffer from PTSD are often subjected to re-living the source of their despair through nightmares and flashbacks, and current treatment results in only occasional success. However, researchers at Stanford University appear to have alleviated PTSD in mice while the rodents slept, by using a new technique which may prove applicable for humans in the future.  Read More

Schematic of titanium pipes being formed

Titanium is a tremendously useful metal and very abundant, yet only 186,000 tonnes (205,030 tons) of it are produced a year and it’s not used very much outside of the aerospace field because it’s so expensive and difficult to forge. To correct this, a team led by André Albert at the Fraunhofer Institute for Surface Engineering in partnership with Thin Films (IST) in Braunschweig, Germany have developed a new process for hydroforming titanium at high temperatures in a single step that promises to make titanium more of an everyday material.  Read More

The ribbon-like material being wound onto a spool, while being sprayed with polymer and st...

When people need a material that’s strong yet lightweight, they usually look to carbon fiber. In the near future, however, they may instead choose to go with composite materials made from stretched carbon nanotubes. These materials could theoretically offer the same strength as carbon fiber at one-tenth the weight, or the same weight at ten times the strength. Researchers from North Carolina State University have recently succeeded in creating such a composite.  Read More

The GeS 'nanoflowers' have petals only 20-30 nanometers thick, and provide a large surface...

Researchers have already turned to the humble sunflower for inspiration to design more efficient Concentrating Solar Power (CSP) plant layouts, and now a team from North Carolina State University has developed a “nanoflower” structure out of germanium sulfide (GeS) that shows great promise for use in energy-storage devices and more efficient solar cells. The secret is the material's ultrathin petals that provide a large surface area in only a small amount of space.  Read More

The AquatiCo ROV prototype

“People will protect what they love, and they love what they know,” says robotics engineer Eduardo Labarca, paraphrasing Jacques Cousteau. That’s why he and his team at Mountain View, California-based 9th Sense Robotics want to start up an online marine exploration project known as AcquatiCo. If it reaches fruition, it will allow computer users anywhere in the world to control an actual ocean-based submarine, while watching a real-time feed from its onboard video camera.  Read More
