Sneezing produces complex fluid cascade, not a simple spray

Here's some incentive to cover your mouth the next time you sneeze: New high-speed videos captured by MIT researchers show that as a person sneezes, they launch a sheet of fluid that balloons, then breaks apart in long filaments ...

Cracking open diamonds for messages from the deep earth

Geochemist Yaakov Weiss deals in diamonds. Not the brilliant jewelry-store kind, but the flawed, dirty-looking ones used more for industry than decoration. Gem-grade diamonds are generally pure crystallized carbon, ...

Liquid crystal research, future applications advance

Contributing geometric and topological analyses of micro-materials, University of Massachusetts Amherst mathematician Robert Kusner aided experimental physicists at the University of Colorado (UC) by successfully explaining ...

Bubble study could improve industrial splash control

(Phys.org)—For the first time, scientists witnessed the details of the full, ultrafast process of liquid droplets evolving into a bubble when they strike a surface. Their research determined that surface wetness affects ...

Mosquitos fail at flight in heavy fog

Mosquitos have the remarkable ability to fly in clear skies as well as in rain, shrugging off impacts from raindrops more than 50 times their body mass. But just like modern aircraft, mosquitos also are grounded when the ...

Ingredients involved in splashing revealed

"Splashing" plays a central role in the transport of pollutants and the spread of diseases, but while the sight of a droplet striking and splashing off of a solid surface is a common experience, the actual physical ingredients ...

Using light to build nanoparticles into superstructures

Scientists in the Center for Nanoscale Materials and Argonne's Biosciences Division have demonstrated a remarkably simple, elegant, and cost-effective way of assembling nanoparticles into larger structures of any desired ...

Researchers kick-start ancient DNA

Binghamton University researchers recently revived ancient bacteria trapped for thousands of years in water droplets embedded in salt crystals.
