Tomorrow in Brief
Metal Theft on the Rise?
As the value of metals increases, so does the likelihood of theft. But it isn’t just the local thugs ripping gold chains off our necks that we’ll have to worry about.
Metal theft may become one of the biggest criminal activities of the twenty-first century, warns University of Indianapolis criminologist Kevin Whiteacre. Targets may include construction sites, vehicle parts, plumbing and electrical equipment, and public infrastructure, where thieves see value not just in the manufactured goods themselves but also in their component metals.
“This has redefined theft to me,” says Whiteacre. “You’re no longer stealing a specific item for its value as an item. You’re stealing it for its constituent parts.” Whiteacre has created a Web site, Metaltheft.net, as a repository of news and research on the phenomenon.

Virtual Lab Rats
The use of laboratory animals has long helped researchers study complex systems, such as the interplay of genetics and environmental factors in disease formation. But these animals need to be fed and housed.
Now, researchers may use computer models with integrated data sets to simulate animal physiology. A project to create a “virtual physiological rat” is under way at the Medical College of Wisconsin in Milwaukee. The project will allow computational biologist Daniel Beard and his team to predict the interaction of a variety of factors within an entire physiological system.
While it won’t eliminate the need for laboratory animals entirely, the project aims to make more efficient use of animal research, to improve understanding of disease, and to advance the goal of creating a virtual physiological human.

Solar Ivy for Walls
The ivy-covered walls adorning university buildings may soon be powering those buildings as well.
Solar Ivy, developed by Sustainably Minded Interactive Technology in New York, is made of small photovoltaic panels that can be created in different shapes and colors to suit the architecture.
Pioneering the application of Solar Ivy is the University of Utah, which used funds raised by students to install the panels in late 2011. The goal is to generate enough electricity for the ivy-covered building to offset the amount of power it buys from the utility company.

Need a lift up from bed to chair? The task is awkward and difficult for most humans, and sometimes results in caregivers wrenching their backs. Not so for robots.
As the population of older people needing nursing care begins to soar in Japan and other graying societies, robots are being developed to provide more of the necessary physical support. This may be as many as 40 lifts a day for individual patients.
Japan’s latest RIBA II (Robot for Interactive Body Assistance), developed by researchers at RIKEN and Tokai Rubber Industries, has improved functionality, more power, and greater sensitivity. Sheets of sensors lining the robot’s arms and chest allow it to detect a patient’s weight accurately, and thus provide gentler and safer lifts.

Aquariums as Farms
Future homeowners, college campuses, and other nontraditional “farmers” may soon be growing their own fish and vegetables while recycling waste.
An experimental food production system is being tested by SUNY ecological engineering graduate student Michael Amadori. The system is a variation on aquaponics (combining traditional aquaculture and hydroponic farming) that incorporates the use of post-consumer food waste.
Instead of being composted (or thrown out), the wasted food is fed to the fish. Then, the fish waste is used for growing vegetables. The goal is to reduce the amount of food waste and lower the cost of raising fish.

March 6, 2014 - I am finally back from Florida and once again sifting through the content my web crawlers and affiliations with social networks that provide me with the fodder I turn into 21st Century Tech blog.
Seth MacFarlane, the multitasking comedian and creator of Family Guy, and other raunchy fare, happens also to be the driving force behind the new version of Carl Sagan's classic science show COSMOS, which will appear Sunday on Fox and simultaneously on other networks, hosted by Neil deGrasse Tyson. I know a number of the writers and producers who have striven to create something stunning, vivid and updated for the 21st Century.
The crisis in Ukraine shows the continued relevance of soft power. Weak in soft power, Russia turned to less effective means to get its way.
I’ve always loved ideas and I think it stems from the fact that I’ve had so many to choose from. But it wasn’t about the sheer number of ideas I got to play with. Rather it was finding that one truly remarkable gem, the golden epiphany, hiding in amongst the others.
Pundits have been wondering aloud what’s going to happen next in the Russia-Ukraine fiasco. For the answer, they might want to look beyond the two countries. What happened in Crimea could happen in many more hotspots throughout the 14 republics that once lived under Moscow rule.
Synthetic Biology and Other Benign Technologies that Could Have a Dark Side: Interview with Seán Ó hÉigeartaigh
Interview with Seán Ó hÉigeartaigh, Academic Project Manager at the Oxford Martin Programme on the Impacts of Future Technology
How do you see the future in fifty years?
Fifty years is a long time frame. If we looked forward to the present day from 50 years in the past, there are some things that we could have predicted. For instance, global population growth and pressure on natural resources, water in particular. However, we couldn’t have predicted the global impact of the internet. My view is that there is likely to be something like that which will change things so predominantly – a potential technological wildcard.
I care about the environment just as greens are supposed to, but I see dogmatic, poorly thought through green policies as a big part of the problem facing the environment. With the greens as its friends, the Earth needs no enemies. Today, I read that solar companies are leaving Spain, where it is usually sunny, to come to the UK, where it usually isn’t, because our previous and existing governments were very keen to demonstrate their green credentials by subsidising solar power. This is obviously counter-productive, as are many other policies thought up by the green community.
