The uBot-5 is dynamically stable, using two wheels in a differential drive configuration for mobility. Dynamically stable robots are well suited to environments designed for humans where both a high center of mass and a small footprint are often required.

Baby boomers are set to retire, and robots are ready to help, providing elder care and improving the quality of life for those in need.

The uBOT-5 carries a Web cam, a microphone, and a touch-sensitive LCD display that acts as an interface for communication with the outside world. “Grandma can take the robot’s hand, lead it out into the garden and have a virtual visit with a grandchild who is living on the opposite coast,” says Grupen, who notes that isolation can lead to depression in the elderly.

Grupen studied developmental neurology in his quest to create a robot that could do a variety of tasks in different environments. The uBot-5’s arm motors are analogous to the muscles and joints in our own arms, and it can push itself up to a vertical position if it falls over. It has a “spinal cord” and the equivalent of an inner ear to keep it balanced on its Segway-like wheels.

A team led by MIT students this week successfully tested a prototype of what may be the most cost-efficient solar power system in the world - one team members believe has the potential to revolutionize global energy production.

The system consists of a 12-foot-wide mirrored dish that team members have spent the last several weeks assembling. The dish, made from a lightweight frame of thin, inexpensive aluminum tubing and strips of mirror, concentrates sunlight by a factor of 1,000 - creating heat so intense it could melt a bar of steel.

To demonstrate the system’s power, Spencer Ahrens, who just received his master’s in mechanical engineering from MIT, stood in a grassy field on the edge of the campus this week holding a long plank. Slowly, he eased it into position in front of the dish. Almost instantly there was a big puff of smoke, and flames erupted from the wood. Success!

Burning sticks is not what this dish is really for, of course. Attached to the end of a 12-foot-long aluminum tube rising from the center of the dish is a black-painted coil of tubing that has water running through it. When the dish is pointing directly at the sun, the water in the coil flashes immediately into steam.

Someday soon, Ahrens hopes, the company he and his teammates have founded, called RawSolar, will produce such dishes by the thousands. They could be set up in huge arrays to provide steam for industrial processing, or for heating or cooling buildings, as well as to hook up to steam turbines and generate electricity. Once in mass production, such arrays should pay for themselves within a couple of years with the energy they produce.

“This is actually the most efficient solar collector in existence, and it was just completed,” says Doug Wood, an inventor based in Washington state who patented key parts of the dish’s design–the rights to which he has signed over to the student team.

So far, the signs are good. The bill commits $500 million for research facilities, infrastructure improvements, and other capital projects; $250 million for tax credits; and $250 million for research grants. The plan is flexible enough to support research at private institutions while making major investments at public universities. Patrick and legislators fended off the most flagrant attempts to divert money into political pet projects with little direct relevance to the biotech industry, such as $49.5 million for a science building at a state college with no graduate science programs.

The tech industry is facing an energy crisis. The cost of power consumption by data centers doubled between 2000 and 2006, to $4.5 billion, and could double again by 2011, according to the U.S. government. With energy prices spiking, the challenge of powering and cooling these SUVs of the tech world has become a major issue for corporations and utilities.

The modern data center is like a vast refrigerator with hundreds or thousands of ovens blazing away inside. Six-foot-tall metal racks stacked with pizza box-size computers, storage devices, and network-routing machines are lined up in rows. Chilled air blows through the equipment from vents in the floors of “cold aisles.” Hot air blows out of the back ends into “hot aisles” and is drawn off and vented out of the building. Inside the centers, there’s a dull roar as large quantities of air shoot through ducts, vents, and computers.

So intense is the competition among tech companies to lower their costs of processing data that some treat information about their energy use like state secrets.

The $4.5 billion spent in the U.S. in 2006 is the equivalent of the electric bills for 5.8 million U.S. households.

“Education in the composites industry is haphazard at best,” admits Gregor Welpton, president of Black Feather Boats (Douglas, Alaska). Although a number of training programs for both engineers and technicians have been spawned over the years, they are essentially independent and, therefore, largely unrelated efforts. The product of universities, community colleges, regional training centers, technical institutes, private training companies and composites vendors, these offerings run a wide gamut from undergraduate and advanced degrees and technical certifications to short courses and periodic seminars. A variety of teaching methods are employed by these programs, including classroom instruction and/or video-based training, video-interactive training and, least likely, hands-on lab work.

“Currently, composites education is being driven by the individual institution,” explains Andre Cocquyt, president of GRPGuru (Brunswick, Maine) and one of the architects of a new composites training curriculum being developed in Brunswick. “There is no consistent approach, no consistent level of education, no qualification,” he adds. The unintended consequence is a dramatic variation in the competency levels of program graduates.

Speaking for many industry business owners, Welpton says the time has come for a coordinated industrywide education effort: “The industry needs an education initiative,” he says, “so that the employers know what they’re getting out of the institutions and the employees know what is expected of them when they show up to work.”

Merck and Harvard just signed an agreement to develop treatments for the bone disease osteoporosis. On Apr. 25 rival Pfizer (PFE) invested $14 million in an alliance with four universities to study diabetes and obesity.

Drugmakers are counting on these deals to solve a persistent problem: underperforming product pipelines. Merck, Pfizer, and others have been losing sales of one blockbuster drug after another as patents expire and competitors charge in with generics. Big drug companies have fought back by spending more on research, yet the number of new medicines approved each year is falling. In the last week of April alone, the U.S. Food & Drug Administration rejected two of Merck’s experimental drugs, prompting the company to lay off 1,200 salespeople.

Past deals between industry and academia have been hampered by patent disputes and tussles over publication rights, as companies tried to thwart academics who want to share their discoveries with colleagues around the world. So now the companies have devised policies allowing their Ivory Tower partners to patent and publish their discoveries, even as they draw the professors more deeply into corporate affairs.

Since the late 1990s, the United States had a modest increase in bachelor’s degree output, from just over 103,000 in 1998–99 to more than 137,000 in 2003–04 before declining slightly to about 129,000 in 2005–06, a growth of nearly 25 percent since 1998–99. India’s expansion at the bachelor’s level was more rapid, with four-year degree holders in engineering, CS, and IT more than tripling in the last seven years, from just over 68,000 in 1998–99 to nearly 220,000 in 2005–06. The fastest growth in bachelor’s degrees, however, appears to be occurring in China. According to the Chinese MoE, the number of bachelor’s degrees awarded has more than doubled in the last four years, from 252,000 in 2001–02 to 575,000 in 2005–06.

While engineering, CS, and IT degree production in the United States has been stable or increasing at all degree levels over the past ten years, a sizable percentage of these degrees are indeed being
awarded to foreign nationals. Statistics collected by the ASEE on bachelor’s, master’s and Ph.D. degrees in engineering indicate that during the 2005–06 academic year, 7.2 percent, 39.8 percent and 61.7 percent of these degrees, respectively, were awarded to foreign nationals (Figure 4). As these figures indicate, the percentage of foreign nationals is significantly higher at the graduate level, especially for Ph.D. degrees.
