Researchers found that sperm whales blowing bubbles while asleep release air, making them less buoyant in the process. This helps them stay underwater without popping to the surface like a cork as they sleep.
Researchers at Osaka Metropolitan University have developed polyethylene rafts that are about five times more durable than traditional bamboo rafts used in oyster farming. The new rafts are designed to be affordable and can withstand harsh weather conditions, reducing damage from typhoons.
Researchers at the Universiteit van Amsterdam triggered mini-earthquakes in a lab by applying a small seismic wave to a granular material. The study shows that these events can be understood using laboratory-scale frictional experiments, and its findings are relevant for understanding remote earthquake triggering in larger faults.
Researchers at the Laureate Institute for Brain Research found significant effects of floatation-therapy on body image and anxiety in patients with anorexia nervosa. The study showed immediate and sustained reductions in body image dissatisfaction and improved anxiety, which remained after treatment and lasted up to six months.
Researchers at Helmholtz-Zentrum Dresden-Rossendorf have developed a new procedure to optimize water usage in mineral beneficiation technology. By using process simulation, the team was able to significantly reduce water consumption, from 4,000 litres per tonne of ore to below 1,000 litres per tonne. This innovation has the potential t...
Researchers used X-ray studies to investigate the floating properties of pumice rocks, finding that surface tension plays a key role in trapping gases within the rock's pores. The study provides new insights into the longevity of these rocks, which can travel thousands of miles on ocean currents.
Researchers develop a new collector technology using water-repelling nanoparticles to recover gold, silver, and copper from waste rock. The process achieves near-100% recovery rate in laboratory experiments.
A new study by Johns Hopkins researchers found that helicopters servicing the Gulf of Mexico experience an average of 5 deaths per year due to mechanical failures and bad weather. Pilot error was a major contributor to 83 crashes, highlighting concerns about safety in oil and gas operations.
