Australian bionic eye successfully implanted

“These results have fulfilled our best expectations” In a major development, Bionic Vision Australia researchers have successfully performed the first implantation of an early prototype bionic eye with 24 electrodes. Ms Dianne Ashworth has profound vision loss due to retinitis pigmentosa, an inherited condition. She has now received what she calls a ‘pre-bionic eye’ implant … Continue reading

Experimental device may keep trucks from jack-knifing

If there’s one thing that truck drivers don’t want their articulated tractor/trailer rigs to do, it’s jack-knifing. This typically occurs when the tractor skids on the road, and the momentum of the trailer causes it to swing out from behind, ultimately resulting in the tractor and trailer being folded up against one another – not … Continue reading

Shading Earth: Delivering Solar Geoengineering Materials to Combat Global Warming May Be Feasible and Affordable

The basic feasibility of SRM with current technology is still being disputed A cost analysis of the technologies needed to transport materials into the stratosphere to reduce the amount of sunlight hitting Earth and therefore reduce the effects of global climate change has shown that they are both feasible and affordable. Published August 31, 2012, … Continue reading

Smallest Antenna Can Increase Wi-Fi Speed 200 Times

Can support wireless speed of 20 Gbps Researchers from A*A*STAR’s Institute of Microelectronics (IME) have developed the first compact high performance silicon-based cavity-backed slot (CBS) antenna that operates at 135 GHz. The antenna demonstrated 30 times stronger signal transmission over on-chip antennas at 135 GHz. At just 1.6mm x 1.2mm, approximately the size of a … Continue reading

Print yourself an airplane with MakerPlane

We firmly believe that everything should be 3D printable. That is, if you’re in the market for some sort of new widget or piece of furniture or you just need to fix something, you should be able to order up a schematic and print it out in your living room. And if you’re in the … Continue reading

New Antibacterial Coating for Sutures Could Reduce Infections After Surgery

Responding to an urgent need for better antibacterial coatings on surgical sutures, scientists are reporting the discovery of a new coating that is almost 1,000 times more effective than the most widely used commercial coating. Their report appears in ACS’ journalLangmuir. Professor Gregory Tew, who is from UMass-Amherst, and colleagues explain that infection at the … Continue reading

Study offers new hope for increasing global food production, reducing environmental impact of agriculture

Just-released Nature paper shows more strategic use of nutrients and water on a global scale could boost production 45 to 70 percent for most crops Can we have enough to eat and a healthy environment, too? Yes—if we’re smart about it, suggests a study published in Nature this week by a team of researchers from … Continue reading

The Chemical Threat to America

It would not take an elaborate plot by Al Qaeda to endanger many lives. SINCE Sept. 11, 2001, the American government, under two presidents, has taken unprecedented steps to ensure the safety of its citizens. Unfortunately, more than a decade later, a major flaw in our national security remains, leaving millions of Americans at risk. … Continue reading

Would You Infect Yourself With Worms For Better Health?

The death of important gut-dwelling parasites that we co-evolved with may be causing the rise in food allergies and other diseases. Now scientists are working on finding ways to have us and our worms live in harmony again. Jim Lahey, founder of in New York, fosters an obsession with microorganisms. Yeasts and bacteria give rise … Continue reading

‘Nano machine shop’ shapes nanowires, ultrathin films

The process could be scaled up for an industrial roll-to-roll manufacturing process A new “nano machine shop” that shapes nanowires and ultrathin films could represent a future manufacturing method for tiny structures with potentially revolutionary properties. The structures might be tuned for applications ranging from high-speed electronics to solar cells and also may have greater … Continue reading
