Providing auxiliary hydrogen power to docked or anchored ships may soon be added to the list of ways in which hydrogen fuel cells can provide efficient, emissions-free energy. Hydrogen fuel cells are already powering mobile lighting systems, forklifts, emergency backup systems and light-duty trucks, among other applications. Now, researchers at Sandia National Laboratories have found that hydrogen

When it comes to the “smell test,” the nose isn’t always the best judge of food quality. Now in a study appearing in ACS’ journal Nano Letters, scientists report that they have developed a wireless tagging device that can send signals to smartphones warning consumers and food distributors when meat and other perishables have spoiled. They

Purdue researchers have created a transparent polymer film that also conducts electricity, introducing an inexpensive organic material for applications such as the screens of electronic devices. While some polymers can already conduct electricity with the help of a process called chemical doping, none have yet been made that conduct just as well in a transparent

An international competition to pave the way for a new generation of rescue robots was dominated by a team of Japanese roboticists who were students in the laboratory of a pioneer in the design of intelligent humanoid machines. The early roboticist, Hirochika Inoue, began work in the field almost a half-century ago at the University of

Monitoring oxygen levels in water has applications for oil spills, fish farming, brewing beer and more – and a professor at Michigan State University is poised to help supply that need. The concept of oxygen sensors isn’t new. The challenge, however, has been manufacturing one that can withstand fluctuations in temperature, salinity, carbon dioxide, phosphates

A way to make imperfectly ripe fruit a thing of the past Have you ever been disappointed by a cantaloupe from the grocery store? Too ripe? Not ripe enough? Luckily for you, researchers from the University of California, Davis might have found a way to make imperfectly ripe fruit a thing of the past. The

National University of Singapore’s (NUS) Faculty of Engineering has invented a novel robotic walker that helps patients carry out therapy sessions to regain their leg movements and natural gait Survivors of stroke or other neurological conditions such as spinal cord injuries, traumatic brain injuries and Parkinson’s disease often struggle with mobility. To regain their motor

FDA approval for pharmaceuticals being developed and tested that treat–and prevent–radiation sickness is years away. Despite the wide availability of potassium iodine to mitigate ingestion exposure to radioactive iodine in the air, food or beverages, there is still no magic medicine to give to people who have been—or will be—exposed to high levels of direct
