How to shelter from a nuclear explosion

There is no good place to be when a nuclear bomb goes off. Anything too close is instantly vaporized, and radiation can pose a serious health threat even at a distance. In between, there is another danger: the blast wave ...

Acetone experiences Leidenfrost effect, no hotplate needed

In doing his due diligence, cleaning his lab equipment, fluid physicist Stoffel Janssens from the Mathematical Soft Matter Unit in the Okinawa Institute of Science and Technology (OIST), Okinawa, Japan, took notice of the ...

Does living near wind turbines negatively impact human health?

Wind turbines are a source of clean renewable energy, but some people who live nearby describe the shadow flicker, the audible sounds and the subaudible sound pressure levels as "annoying." They claim this nuisance negatively ...

MEMS nanoinjector for genetic modification of cells

The ability to transfer a gene or DNA sequence from one animal into the genome of another plays a critical role in a wide range of medical research—including cancer, Alzheimer's disease, and diabetes.

Acoustic levitation made simple

A team of researchers at the University of São Paulo in Brazil has developed a new levitation device that can hover a tiny object with more control than any instrument that has come before.

Droplet spread from humans doesn't always follow airflow

The World Health Organization has warned that aerosol transmission of COVID-19 is being underestimated. If aerosol spread is confirmed to be significant, as suspected, we will need to reconsider guidelines on social distancing, ...

A bar magnet creates chaos in plasma

Placing a magnet on your refrigerator might hold up your calendar, but researchers from India's Saha Institute of Nuclear Physics found that placing one outside a plasma chamber causes a localized, fireball-like structure. ...

New bubbling mechanism discovered in physics

A group of researchers at Zhejiang University's State Key Laboratory of Fluid Power and Mechatronic Systems, in Hangzhou, China, recently discovered that a new bubbling mechanism may exist within the realm of physics.

Modeling Amazonian transitional forest micrometeorology

What can mathematical modeling teach us about the micrometeorology of the southern Amazonian 'transitional' forest? Quite a lot, it turns out. This particular forest is located between the rain forest of the Amazon Basin ...
