A bioplastic made from chitin in the shells of crustaceans and insects is mixed with so-called meat glue, a culinary ingredient, to create a glue that bonds with living tissue. The development at Harvard University's Wyss Institute is seen as a solution for quick battlefield treatment of gaping wounds and for securing biomedical implants and microfluidic devices in the body.
Penetrating a living cell by cutting through its outer wall without destroying the cell has been a long-standing challenge for scientists. A solution is at hand in the form of a nanoblade consisting of a glass pipette with a thin surface layer of titanium powered by a brief laser burst.
A modular, unmanned ground vehicle capable of a variety of missions assisting or replacing troops has passed early field tests. The tracked UGV from Milrem and ST Kinetics runs on a hybrid diesel-electric system for up to 10 hours and can be controlled remotely or programmed to operate autonomously.
Nanocarriers are promising in their ability to deliver cancer-killing drugs to tumors but encounter difficulties getting the drugs past the pressure zone between the tumor and nearby tissue to reach the key low-oxygen parts of the tumor. Researchers are working on an alternative based on a bacterium that thrives in deep, oxygen-scarce waters by maneuvering along local magnetic field lines.
Automated, robotic maintenance may be on the way for the world's roads. A Georgia Tech team is developing a system that uses stereo camera technology and LEDs somewhat like the beam of a flashlight cast at different angles to detect road cracks, which are then filled by a multinozzle system that projects pressurized, heated asphalt.
Toyota says it will be able to bring a new and improved electrically powered car to market in "several years," thanks to a complex method it has developed to track the path of ions in lithium-ion batteries. The development will allow Toyota to efficiently test new battery materials and structures and produce what the company anticipates will be a 10% to 15% improvement in vehicle range.
Lower maintenance needs and greater efficiency are among the merits of General Electric's new management suites for digital power plants. The Predix-based software for power producers, energy managers and grid operators is said to pare unplanned downtime as much as 5% for gas, steam and nuclear plants and cut 25% from operations and maintenance costs.
Aging infrastructure and newly budget-conscious governments and businesses mean that maintenance and repair work across Australia will grow twice as fast as the overall economy, said Chris Sutherland, CEO of labor hire firm Programmed. The driving element is a low-growth environment forcing governments and companies to squeeze more life out of existing assets, Sutherland said.
The University of Idaho and Inergy, a marketer of portable solar generators, are working on a bigger generator that would produce 5 kilowatts of power, enough for a home, and still be portable. The key, they believe, will be using gallium nitride in place of silicon to keep down size and heat production for a unit that homeowners could simply plug into their home's solar panel circuitry.
If you want to build a real connection with your team, you need to be honest about your emotional state and admit that you don't always have the answers, writes executive coach Nozomi Morgan. Strive to be approachable, she advises.
