Can tablet computers make greater inroads in the PC market?

This week’s question concerns tablet computers. Apple Computer is strongly rumored to soon unveil a tablet computer able to play music and video, read E-books, and provide Internet access. Several PC makers, including Motorola and Hewlett-Packard, also demonstrated tablet computers at the recent Consumer Electronics Show. While tablet computer proponents believe these devices can carve out a market niche, skeptics say tablet computers will have difficulty competing in a market crowded with netbooks and smartphones as well as laptops and PCs.

What do you think? Can tablet computers make greater inroads in the PC market? Yes or no?

Oil Refineries Could Improve Energy Efficiency With New Method

Chemical plants spend from 50 to 70 percent of their energy in "separations," which are usually distillation steps required to separate a raw material into various products. An energy-efficient Purdue University method rearranges the distillation sequence needed to separate crude petroleum into products.

Should whole body imaging be used for airport security?

The first Question of the Week for 2010 concerns airline security. The recent foiled attempt by a Nigerian terrorist to set off a bomb aboard a Northwest Airlines flight landing in Detroit has renewed concerns that current X-ray technology is insufficient in detecting concealed weapons and substances. The Transportation Security Administration (TSA) already has a pilot program in place at six airports deploying millimeter-wave machines, which produce a 3-D image of the body, in place of X-ray machines. But some government officials worry these machines violate the privacy of individuals such as women and children.

What do you think? Should whole body imaging be used for airport security? Yes or no?

Bacteria Turns Carbon Dioxide Into Liquid Fuel

Researchers from the UCLA Henry Samueli School of Engineering and Applied Science have genetically modified a cyanobacterium to consume carbon dioxide and produce the liquid fuel isobutanol, which has great potential as a gasoline alternative. The reaction is powered directly by energy from sunlight, through photosynthesis.
