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 [...]
This summer, a small armada of vessels from all over the globe will converge in the Pacific Ocean. Their arrival is expected to herald what arguably can be called one of the more creative environmental cleanup projects. As many as fifty boats consisting of everything from research vessels to private cruisers, sailboats and commercial fishing vessels will track the Pacific’s Great Garbage Patch as it makes its rocky journey through currents between Hawaii and the California coastline.
The mega exploration, as the team at the nonprofit organization, The Ocean Cleanup, calls it, will help the organization close in on their efforts to clean up the [...]
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 [...]
Oral arguments were heard on Tuesday in a long-running lawsuit brought by two teenagers against the state of Oregon. The teens are seeking to force the state to take more aggressive action on climate change and thereby better protect the planet for future generations.
The suit is one of dozens of legal actions and petitions filed in virtually every state, along with federal courts, as part of a campaign spearheaded by the Oregon-based nonprofit Our Children’s Trust. “Our purpose is to protect earth’s natural systems for current and future generations,” the organization declares on its Web site. “We are here to empower and support youth as they stand up for their lawful [...]
