Scientists have already devised systems that allow electronic devices to
scavenge power from ambient electromagnetic energy sources such as radio waves. While the technology has generally been limited to small devices such as wireless sensors,
a research team has recently created a scavenging system that charges a
smartphone's battery, letting it last up to 30 percent longer per
charge – and the system does so using radio signals emanating from the
As we approach the fifth anniversary of the Deepwater Horizon oil spill, scientists are still trying to develop better ways of removing oil from water
. Now, researchers at The Ohio State University believe that they may be onto something. They've developed a stainless steel mesh that allows water to pass through, but that stops oil.
People running outdoors speed up and slow down without thinking about it – it just happens. On a treadmill, however, they have to manually adjust the speed of the machine. Perhaps they won't have to for too longer, however. Scientists at The Ohio State University have developed a prototype treadmill that detects when its user's running speed changes, and adjusts its own speed accordingly.
Just two days after opening, The London Millennium Footbridge was closed to eliminate its sway. Turns out staying with the sway would have had its benefits, as researchers have found that it reduces the amount of energy expended when walking across the bridge.
Signs of Duchenne muscular dystrophy (DMD) can start to appear in boys as young as six, leading to deterioration of the heart muscles and ultimately death. Pharmaceuticals aimed at controlling high blood pressure have been used to treat the one in 3,500
young males suffering from the condition, but a new study suggests that a novel combination of these drugs could slow the decline in heart function earlier on, and in promising new ways.
With video games having previously been found to improve decision making speeds
and the brain's capacity to learn
, scientists have now created challenging computer games with a fun element that significantly improved depth perception and binocular vision in people with a lazy eye. Unlike the traditional patch used to treat the condition, the video games encourage both eyes to work together.
When you hurt a muscle, it's usually advisable to lay off extensive use of it, until it's had a chance to heal. Well, your heart is a muscle. Although you can't just stop using it altogether when it's damaged, you can make its job easier. That's what Sunshine Heart's C-Pulse system was designed to do, and a current study suggests that it does indeed help victims of heart failure recover more quickly.
We don't hear from boutique automotive manufacturer Venturi very often, but when we do, it's always interesting news. The creator of the world's first production electric sports car
revealed an updated version of its 2010 America
electric dune buggy at this year's Paris Motor Show. The new concept car combines the high performance and handling of a sports car with the ever-fun design of a sand-hungry dune buggy.
Researchers at Ohio State University (OSU) have created a dye-sensitized solar cell that stores its own power by "breathing" air to decompose and re-form lithium peroxide. Its creators believe the device, which effectively combines a battery and a solar cell in one, could reduce renewable energy costs by 25 percent.
While they may not be quite as well-known as migraines, cluster headaches are even more painful, and can occur several times a day. There's presently no cure, although a new "neurostimulator" is claimed to help control them. A US clinical trial of the device has just begun, with a test subject recently having had one implanted beneath his cheekbone.
