We may not yet have the liquid metal depicted in the Terminator movies, but scientists have now developed something that’s vaguely along the same lines. German materials scientist Dr. Jörg Weißmüller and Chinese research scientist Hai-Jun Jin have created a metallic material that can change back and forth between being strong but brittle and soft but malleable, via electrical signals.  Read More

A new type of stem-cell-seeded bandage, designed to heal torn meniscal cartilage such as  ...

Every year, approximately 1.7 million people in the U.S. and Europe tear a meniscus – children and athletes are especially prone to such injuries. But first, just what is a meniscus? It’s one of two pieces of cartilage located inside each knee, that provide a cushion between the tibia and the femur. While smaller tears can heal on their own, larger tears often require a partial or complete removal of the meniscus. Within several years, this can result in the early onset of osteoarthritis. Recently, a new type of stem cell-seeded bandage, developed at the University of Bristol, has been approved for a clinical trial on meniscal tears. It may greatly reduce the need for menisectomies.  Read More

The Golf Ball Wrangler is a device that lets entrepreneurs harvest golf balls from the bot...

When most golfers hit a ball into the middle of a water trap, they probably just assume that the ball is destined to remain underwater for all eternity. Various enterprising individuals, however, regularly ply the depths of such ponds and lakes to retrieve those lost balls, for resale to golfers. While some of these entrepreneurs reach out into the water as far as they can with rake-like contraptions, most of them don scuba gear and go treasure-hunting. A new invention, the Golf Ball Wrangler, can now be added to their arsenal – and it has advantages over both rakes and diving.  Read More

At its Worldwide Developers Conference today, Apple officially unveiled iOS 5, the latest version of its mobile operating system for iPhone, iPad and iPod touch. The new system reportedly includes over 200 new features, one of the more noteworthy of which is the iCloud online data storage service. iCloud includes 5GB of internet-based memory space, and it automatically syncs all of a user's iDevices whenever new files are added to any one of them. iOS 5 will be available to consumers as of this Fall.  Read More

Researchers involved in the ALPHA experiment at Switzerland’s CERN complex announced yesterday (June 5) that they have succeeded in using the facility's antiproton decelerator to trap antimatter atoms for 1,000 seconds – or just over 16 minutes. This was reportedly enough time to begin studying their properties in detail, which has been the goal of ALPHA since the project began in 2005.  Read More

A scientist has proposed that ships could move through the ocean with less friction, if th...

Want to make a ship move faster through the water? Well, one thing that you can do is paint its hull with low-friction or anti-biofouling paint, to keep barnacles and other marine organisms from growing on it. According to Prof. Derek Chan, from the University of Melbourne's Department of Mathematics and Statistics, another approach that should work is to heat that hull up to a temperature of over 100C (212F). His proposed method is based on a 255 year-old principle known as the Leidenfrost effect.  Read More

Brain-implanted polymer-coated electrodes could be used to detect and prevent seizures (Im...

In the future, people who are prone to seizures may get an array of electrodes implanted in their brains. These electrodes would be capable of detecting the onset of a seizure, and then releasing medication to prevent it from happening. While it might sound far-fetched, scientists at the University of Pittsburgh have already demonstrated the technology on lab rats.  Read More

Researchers have harnessed the energy generated by heavy machines, and used it to cut thei...

Many hybrid cars feature regenerative braking – they harness the energy generated when they brake, and store it in the battery for later use. This helps maximize the amount of time that the car can run on one charge. One can’t help but wonder, then, how much energy could be harvested from heavy-duty construction, mining and agricultural machines, as they go about their business. A group of researchers from Finland’s Aalto University decided to find out, and reportedly ended up cutting those machines’ fuel consumption by 50 percent.  Read More

After spending 70 days driving through 14 countries on four continents, three Mercedes-Benz hydrogen cell vehicles have successfully completed their 30,000-kilometer (18,641-mile) F-CELL World Drive. The trio of B-Class F-CELL automobiles left Stuttgart on January 30th, along with an entourage of support vehicles. After traversing a variety of highways, city streets and even some unpaved country roads, they crossed the finish line in front of Stuttgart’s Mercedes-Benz Museum this Wednesday (June 1st).  Read More

If there was one thing that last year's Gulf of Mexico oil spill showed us, it was that there were no particularly good systems in place for containing and removing such spills while the oil is still out at sea. One year later, although many companies and individuals have come forward with their concepts for such systems, little has actually been developed to the point of being ready for deployment. In order to generate some incentive, and provide financial support to the cream of the crop, the X PRIZE Foundation is now in the midst of its US$1.4 million Wendy Schmidt Oil Cleanup X CHALLENGE. Although the competition has been under way since January, the ten finalist teams were announced just last week.  Read More
