Regular training improves maximal oxygen uptake (VO2max), which is a well-established measure of physical fitness. However, just how much exercise, and how intense that exercise should be to deliver the biggest benefit remains to be defined. Now, researchers from the KG Jebsen – Centre of Exercise in Medicine at the Norwegian University of Science and

Research could guide business and political decisions as well as charity work A business may build a better reputation as a good corporate citizen by donating $100,000 to ten charities, as opposed to $1 million to one charity, suggested University of Missouri anthropologist Shane Macfarlan. Contrary to earlier assumptions in theoretical biology, Macfarlan’s research found

In culmination of a decade’s work, RoboBees achieve vertical takeoff, hovering, and steering Last summer, in a Harvard robotics laboratory, an insect took flight. Half the size of a paper clip, weighing less than a tenth of a gram, it leapt a few inches, hovered for a moment on fragile, flapping wings, and then sped

Researchers at Université Laval’s Faculty of Science and Engineering and its Center for Optics, Photonics, and Lasers have created a smart T-shirt that monitors the wearer’s respiratory rate in real time. This innovation, the details of which are published in the latest edition of Sensors, paves the way for manufacturing clothing that could be used

Researchers at UCL have developed a new antibacterial material which has potential for cutting hospital acquired infections. The combination of two simple dyes with nanoscopic particles of gold is deadly to bacteria when activated by light – even under modest indoor lighting. And in a first for this type of substance, it also shows impressive

On Monday, NASA announced that its advanced ion propulsion engine operated for 48,000 hours, or five and a half years – and that’s without stops for fuel or coffee. Developed under NASA’s Evolutionary Xenon Thruster (NEXT) project, the engine now holds the record for the longest test duration of any type of space propulsion system. NEXT is

Two types of raw materials are currently used for biorefining and biofuel production: carbohydrates and lipids. Biofuels like ethanol are derived from carbohydrate raw materials such as sugars and lignocellulose, while biodiesels are derived from another raw material, lipid-rich vegetable oil. In a study published online March 6 in the journal Nature Biotechnology,researchers at the UCLA

This breakthrough highlights new possibilities for integrating high-definition full color displays in wearable electronics. The scientific team, from the Institute for Basic Science (IBS) and Seoul National University, has developed an ultra-thin wearable quantum dot light emitting diodes (QLEDs). The electronic tattoo is based on current quantum dot light emitting diode (QLED) technology. Colloidal quantum
