While just about everyone knows that bats locate prey in the dark using echolocation, one thing that many people may not
realize is the fact that horseshoe bats are particularly good at it.
With this in mind, engineers at Virginia Tech are now developing a sonar
system that emulates the system used by those bats. Once perfected, it
could be a much more compact and efficient alternative to traditional
manmade sonar arrays.
Hydrogen is the ideal gas for use in low-emissions combustion engine or fuel cell-powered vehicles, due to its almost non-existent greenhouse gas emissions. Production costs, however, are higher compared to gasoline and around 95 percent of it is currently produced, somewhat counter-intuitively, from fossil fuels. Now researchers at Virginia Tech claim to have created a method to produce hydrogen fuel using a biological technique that is not only cheaper and faster, but also produces hydrogen of a much higher quality ... and all from the leftover stalks, cobs, and husks of corn.
Further to a list of side effects ranging from mildly unpleasant to just plain awful, the scattergun nature of chemotherapy often sees healthy tissue damaged along with the cancerous cells. Attacking these cancer cells
with better precision
would lead to more effective treatments and reduce harmful side effects, and has been a primary objective for researchers. Among this group is a team of scientists that has developed a way of administering cancer-fighting chemicals using an electric field that is claimed to enable a highly-targeted form of treatment.
If there's one job that a person would probably prefer to lose to a robot, it would be fighting fires aboard ships. To help make such a vision a reality, the US Navy and the Office of Naval Research (ONR) released details of demonstration exercises conducted by their Shipboard Autonomous Firefighting Robot (SAFFiR) aboard the fire training ship USS Shadwell last November.
In a small taste of things to come
in military operations, the US Marine Corps has tested a self-driving
mini-truck as part of the 2014 RIMPAC international naval exercise.
So first of all ... yes, flying snakes do exist. Disappointingly, though, they don't have scaly dragon-like wings. Instead, they're able to flatten out their bodies after launching themselves from tree branches, proceeding to glide through the air for up to 100 feet (30.5 m). Recently, scientists figured out why that technique works as well as it does. Their findings could have some major applications for us humans.
An important element to the notion of self-driving cars is that they are able to communicate between each other and surrounding infrastructure. While automotive manufacturers have begun to explore this technology
and even banded together
to hasten its emergence, the Virginia Tech Transportation Institute has been quietly working toward a similar goal. With the an award of US$1 million in funding courtesy of the US Department of Transportation, its researchers hope to develop a framework to facilitate a safe future for autonomous vehicles.
Even today's best rechargeable lithium batteries do lose their ability to hold a charge after a while, and are considered toxic waste once discarded. In just a few years, however, they may be replaced by batteries that are refillable and biodegradable, and that will also have a higher energy density yet a lower price ... and they'll run on sugar.
Although the causes of world hunger are numerous, it certainly doesn’t help that factors such as arid conditions and limited land space make it difficult to grow food crops in certain places. If people in those areas could eat foods derived from plants that are hardy to the region, but that aren’t considered nutritious, it would go a long way towards addressing the problem. Well, that may soon be a reality, thanks to a newly-developed process that allows cellulose to be converted into starch.
Last year, a team of researchers from the Virginia Tech College of Engineering unveiled RoboJelly
– a robotic jellyfish in development since 2009, that’s about the size of a man’s hand. While the squishy little robot is certainly an impressive feat of engineering, the same team has now created a bigger, better jellybot, known as Cyro.
