Efficiently producing and storing energy – such as for implanted medical systems – is a challenge for our society. A biocatalyst-polymer system could take on both tasks at once. “We see this work as a starting point for future strategies in the development of new, highly functional and also affordable electrical sources of energy on

Without prompt care, a badly wounded soldier can easily bleed to death while being transported to a distant medical station. Two traditional treatments—tourniquets and medicated gauze pads—often cannot stop the blood loss from a deep wound at the neck, shoulder or groin. To give these soldiers a fighting chance at survival, Johns Hopkins undergraduates have

The discovery has applications in signage, posters, writing tablets, billboards and anti-counterfeit technology Chemists at the University of California, Riverside have constructed liquid crystals with optical properties that can be instantly and reversibly controlled by an external magnetic field. The research paves the way for novel display applications relying on the instantaneous and contactless nature

New research from the University of Liverpool has identified the role of a specific protein in the human body that can help prevent the survival and spread of eye cancer, by initiating cancer ‘cell-suicide’. The new findings may help revolutionise the approach to metastatic uveal melanoma (UM) – a cancer that arises from the pigment

Administering antiparalytics topically via a nasal spray A team of researchers led by Dr. Matt Lewin of the California Academy of Sciences, in collaboration with the Department of Anesthesia at the University of California, San Francisco, has pioneered a novel approach to treating venomous snakebites — administering antiparalytics topically via a nasal spray. This new,

Pirated goods cost German industry billions, and expensive industrial goods like machining systems are becoming a growing target. Scientists are turning the tables on the forgers by studying their methods and developing anti-counterfeit solutions. The annual cost to industry of illegal copies of branded products is estimated at a staggering 650 billion U.S. dollars worldwide,

Using a new class of artificial materials, scientists at Duke University have designed a sensor that compresses images far more efficiently than existing technologies like JPEG. The materials, called metamaterials, have exotic qualities that bend light, X-rays and radio waves in unusual ways. While they are barely a decade old, they are fast falling in cost and

Ocean health index provides first global assessment combining natural and human dimensions of sustainability Using a new comprehensive index designed to assess the benefits to people of healthy oceans, scientists have evaluated the ecological, social, economic, and political conditions for every coastal country in the world. Their findings, published today in the journal Nature, show that

For a newborn giraffe or wildebeest, being born can be a perilous introduction to the world—predators lie in wait for an opportunity to make a meal of the herd’s weakest member. This is why many species have evolved ways for their juveniles to find their footing within minutes of birth. It’s an astonishing evolutionary feat
