Strains of E. coli and salmonella kill about 1,250 Americans and infect more than 2 million others each year. As a result, government researchers have expanded their testing program for slaughter houses, with the focus on methods to speed tests for the deadly bacteria. They may not have to look beyond a new testing device developed at Springfield (MA) College. Most existing food tests yield initial results in two to three days, sometimes letting bad meat reach consumers, threaten health, and force recalls. The Springfield College test, according to inventors Chun-Kwun Wun, a microbiologist, and Frank J. Torre, a chemist, can check for E. coli and salmonella within 8 to 24 hrs. The core of the test, performed in a specially designed petri dish, contains chemicals that encourage the bacteria to migrate toward a serum containing antibodies for the strain of microbe under test. When bacteria and antiserum collide, they clump together to form a visible, cream-colored line--the indicator of a positive result. The inventors say the test will cost considerably less than most others and be easier to use. "We can actually grab anybody from the street and train them within two to three hours to do the test," says Wun. The college hopes to license the patented test so that it will reach the market possibly by the end of the year. Phone (413) 748-3044.
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
