  • Cable car planned for world's largest cave

    A Vietnamese resort company has been granted approval to begin surveys to build a 10.6 kilometer long cable car in the world’s largest cave, the UNESCO-listed Son Doong in north-central Quang Binh province in Vietnam.

  • Record efficiency for converting solar energy to hydrogen without rare metals

    Scientists from Ecole Polytechnique Federale de Lausanne (EPFL) in Switzerland have created a solar water splitting technique that uses common materials. They have also achieved a record solar energy to hydrogen conversion efficiency of 12.3% in the ...

  • Camera system sees around corners without using a mirror

    Researchers from the University of Bonn in Germany and the University of British Columbia in Vancouver, Canada have developed a camera that can see around corners without the aid of mirrors. The system can reconstruct the shape of objects using diffu...

  • Scientists eliminate HIV from cultured human cells

    Researchers from Temple University School of Medicine have discovered how to permanently extricate HIV-1 from human cells, possibly avoiding the need for lifelong drug treatment. Though in its very early stages, this may prove to be a critical step i...

  • By-product hydrogen used to power fuel cell pilot plant

    By-products are common to most industries. Some are harmless, some dangerous and others useless. Others are simply under-utilized. Finland's VTT is using hydrogen generated as a by-product of the sodium chlorate production process in its pilot-scale ...

Eye tracking technology based on watching music videos has been used to determine the loca...

Brain injuries are complicated things and even now not fully understood. Researchers at the NYU Langone Medical Center have completed a study that suggests eye tracking technology may be able to help locate and determine the extent of brain injuries as well as monitor recovery. The key to this method is its simplicity – the required eye tracking analysis can be achieved while patients watch music videos for a few minutes.  Read More

Hector, the stick insect-inspired robot built by a research team at Bielefeld University in Germany that we first covered in 2011, could be forgiven for feeling lonely as the only one of its kind in world, but has lately been too busy learning to walk to worry on its unique status. It is hoped that Hector, which stands for Hexapod Cognitive autonomously Operating Robot, will benefit not only roboticists but also biologists interested in animal movement.  Read More

Mouse kidneys, liver, and pancreas imaged after treatment with a variety of protocols: a s...

Japanese researchers have found a way to turn tissue transparent in mice, allowing them to see cellular networks and gain a better understanding of biological systems. Researchers say this may ultimately lead to deeper comprehension of autoimmune and psychiatric diseases given it can assist in 3D modelling of organs including the brain.  Read More

Bitcoins can now be exchanged to buy Microsoft apps and games (Photo: Shutterstock) Microsoft has quietly announced that its customers can now use bitcoin to purchase certain products through third party payment processor BitPay, which also supports tech sales site TigerDirect and Virgin’s space flight offshoot Virgin Galactic.  Read More

The Ethiopian government has rolled out a new phone service that farmers can call to get information on crops in their native languages. The 8028 service also “pushes” targeted information to people in certain areas. A press release from the government says that three million people have used the pilot project service since its inception in July.  Read More

Researchers have achieved a solar energy to hydrogen conversion efficiency of 12.3% using ...

Using solar energy to split water into its component parts, thereby allowing the solar energy to be stored as hydrogen fuel, generally involves one of two methods: using photoelectrochemical cells to directly split the water, or using solar cells to produce electricity to power an electrolyzer that separates the water molecules. One problem associated with the latter method is that it currently relies on rare metals. But now scientists from Ecole Polytechnique Federale de Lausanne (EPFL) in Switzerland have managed to do so using common materials, and have achieved a record solar energy to hydrogen conversion efficiency in the process.  Read More

Researchers at ANU have replicated the primary capture of energy from sunlight (Photo: Shu...

Researchers at the Australian National University are one step closer to creating an artificial photosynthesis system after replicating one of its crucial steps. The development may lead to an abundant source of hydrogen, a cheap and clean fuel that could replace all petroleum products.  Read More

Artist's rendering of synthetic platelets that mimic, and outperform, natural platelets (I...

The skin is the body's first line of defense against infection. And when this barrier is broken, or an internal organ is ruptured, it is the process of coagulation, or clotting, which relies largely on blood cells called platelets, that seals the breach and stems the flow of blood. Researchers at UC Santa Barbara have now synthesized nanoparticles that mimic the form and function of platelets, but can do more than just accelerate the body's natural healing processes.  Read More

The wearable DynePod

American startup Dynepic understands something every small child does: toys can, and do, talk to each other. And you can talk to them, too. Dynepic is aiming to develop an "Internet of Toys" architecture where toys and their controlling devices – the DynePods – are connected and controllable via an open source cloud system which can be programmed from an iPad.  Read More

Italian start-up Youbionic has created a functional, myoelectric bionic hand using 3D printing and Arduino components. While still at prototype stage, the company says that its research will result in a prosthetic hand that costs a tenth or less than other models on the market.  Read More
