American scientist Jeff Leach performed his own fecal transplant with stool borrowed from a hunter gatherer tribesman to better understand the changing nature of gut bacteria ecosystems. Mr Leach was working with the Human Food Project to study to Hadza tribe of Tanzania and the way their gut bacteria may differ from those of people in the West.  Read More

'The major question is, why would we not eat insects?' (Photo: Shutterstock)

Jiminy Cricket may be able to do more than guide our consciences: he, or his kin, may also provide food security solutions for a growing and hungry world. However, the notion of insects-as-food struggles to find widespread traction amid problems with standardization of food safety standards, government disinterest and only a small body of research. So is there a future for cricket sushi or fried silk worms?  Read More

A London-based label has created a line of clothing inspired by George Orwell's 1984 featuring pockets which can block all wireless transmissions, meaning your phone cannot be hacked or credit card details stolen.  Read More

London researchers have revealed that stroke patients in a pilot study all showed improvem...

A pilot study undertaken by researchers from Imperial College Healthcare NHS Trust and Imperial College London has shown promise in rapid treatment of serious strokes. The study, the first of its kind published in the UK, treated patients using stem cells from bone marrow.  Read More

Researchers with the Lawrence Berkeley National Laboratory and the University of California Berkeley have measured what is believed to be the smallest force yet recorded – 42 yoctonewtons, or a septillionth of a newton.  Read More

Upon approval for use by the US, a generic version of Gilead's HIV drug TAF will be made a...

Medicine Patent Pool (MPP), a not-for-profit organization, has partnered with pharmaceutical company Gilead Sciences to produce a generic version of a new HIV treatment drug in India and China that will be distributed in 112 countries.  Read More

By-products are common to most industries. Some are harmless, some dangerous and others useless. Others are simply under-utilized. VTT Technical Research Centre of Finland is using hydrogen generated as a by-product of the sodium chlorate production process in its pilot-scale power plant to produce electricity.  Read More

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 in permanently defeating the disease.  Read More

The camera uses diffused light instead of mirrors to see around corners

Peeking around a corner has long been a staple of spy films and TV, from Get Smart to 007. Researchers at the University of Bonn in Germany and the University of British Columbia in Vancouver, Canada have found a better way than poking a makeup mirror about, however: a camera system that can reconstruct the shape of objects using diffusely scattered laser light.  Read More

As nocturnal creatures, moths need to maximize how well they can see in the dark whilst remaining less visible to avoid predators. This ability to collect as much of the available light as possible and at the same time reflect as little as possible, has inspired Researchers at the Swiss Federal Laboratories for Materials Science and Technology (Empa) to design a new type of photoelectrochemical cell using relatively low cost materials.  Read More
