Dousing Flames with Low-Frequency Sound Waves

A new type of extinguisher that uses sound waves to put out fires has been built by two engineering students in the US. Both chemical- and water-free, the invention offers a relatively non-destructive method of fire control, which could find applications in fighting small fires in the home, and the researchers now hold a preliminary patent application for their device.

While the concept of using sound waves to extinguish flames is not new, previous attempts to realize the principle – including efforts by teams at West Georgia University and the US Defense Advanced Research Projects Agency (DARPA) – had not been successful.

Undeterred by this, as well as initial [...]

Scientists Found a Way to Turn Deadly Female Mosquitoes into Harmless Males

A global team of scientists have found a way to turn female mosquito embryos into males at a genetic level, according to a paper published in Science Express. The finding could really come in handy, since females are the ones that bite, constantly hunting for blood to develop their eggs.

For some of us, mosquitoes are merely an annoyance we can solve with a simple swat or two. But in many parts of the world they carry deadly diseases and are major threat to the health of a population. There are about 200,000 cases of yellow fever each year. And of these, 30,000 result in death. There has been a number of efforts over the years to solve this problem, but the process usually [...]
