When a vehicle travels over a wet or flooded road, water builds up in front of the tire and generates a lift force. In a phenomenon known as hydroplaning, this force can become large enough to lift the vehicle off the ground.
Water issuing from an ordinary faucet tells a complex tale of its journey through a pipe. At high velocities, the faucet's gushing stream is turbulent: chaotic, disorderly—like the crash of ocean waves.
Researchers at The University of Manchester in the UK have discovered that the Hall effect—a phenomenon well known for more than a century—is no longer as universal as it was thought to be.
(Phys.org)—A trio of researchers affiliated with the University of Ulm in Germany and the Smithsonian Tropical Research Institute in Panama has found that one species of bat has a method of collecting nectar that has never ...
For more than a decade, mathematicians and computational scientists have been collaborating with earth scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) to break new ground in the modeling of complex flows ...
A new study is highlighting a need for widespread use of better face masks and the importance of good ventilation to mitigate the spread of COVID-19 indoors.
(Phys.org) —Researchers at the Georgia Institute of Technology have discovered that mammals above a certain size appear to conform to what they have dubbed, the "law of urination"—that is, mammals of all sizes, they report, ...
One way to reduce the damage caused by avalanches in the mountains is to place obstacles in their path. These obstacles can be artificial barriers or natural forests. Knowing how the avalanche interacts with obstacles is ...
Researchers have developed an adaptive liquid lens based on a new electrically responsive fluid called dibutyl adipate (DBA) that changes focal length when a voltage is applied. The lens is lightweight, compact and simple ...
The Venus's flower basket sponge could inspire the buildings, bridges and even aircraft of tomorrow, thanks to its performance under pressure and ability to go with the flow—literally.
