Will humans be extinct in 100 years?

This week's question concerns the world-renowned Australian scientist Professor Frank Fenner - who helped to wipe out smallpox - and his prediction that humans will probably be extinct within 100 years. His reasoning includes overpopulation, environmental destruction, and climate change. Fenner stated that homo sapiens will not be able to survive the population explosion and "unbridled consumption," and will become extinct, perhaps within a century, along with many other species.

What do you think? Will humans be extinct in 100 years?

Does your online persona accurately reflect who you are in the real world?

This week's question concerns our online "personas". While social networking sites such as Twitter and Facebook encourage members to use their real identities, a recent study on the usage habits on these sites has shown there's little correlation between how people act on the Internet and how they are in person. For example, if you're the type who is overly chatty or arrogant on Twitter, this doesn't necessarily reflect on how you may act in the real world.

What do you think? Does your online persona accurately reflect who you are in the real world?

Yes or no?

Promise for Hydrogen-Fueled Cars

A new process for storing and generating hydrogen to run fuel cells in cars has been invented by chemical engineers at Purdue University. The process uses a powdered chemical called ammonia borane, which has one of the highest hydrogen contents of all solid materials.

Should CO2 emissions be regulated?

This week’s question concerns the EPA’s regulation of greenhouse gas emissions. Last Thursday, the US Senate failed to pass legislation that would have prevented the Environmental Protection Agency (EPA) from regulating CO2 emissions from large factories, electric power companies, and automobiles.

What do you think? Should CO2 emissions be regulated? Yes or no?

Scientists Use Nanoscale Architecture to Make Efficient Solar Cell

A thin film solar cell must be thick enough to collect a sufficient amount of light, yet it needs to be thin enough to extract current. Boston College physicists found a way to resolve the "thick & thin" challenge through a nanoscale solar architecture based on the coaxial cable.

Should Google be liable for "bad" directions that lead to injury?

This week's question concerns a recent news item about how a Utah woman injured by a motorist while following a Google Maps route has filed a lawsuit claiming Google supplied unsafe directions (the motorist is also named in the lawsuit). The woman used her phone to download directions from one end of Park City, UT, to the other. Google Maps led her to a four-lane boulevard without sidewalks that was "not reasonably safe for pedestrians," according to the lawsuit. The woman believed she could reach a sidewalk on the other side of the boulevard and therefore tried to cross. A car struck her before she even reached the median. The woman received multiple bone fractures that required six weeks of rehabilitation.

What do you think? Should Google be liable for "bad" directions that lead to injury? Yes or no?

Formula for the Removal and Remediation of Polychlorinated Biphenyls in Painted Structures

An activated metal treatment system (AMTS) removes and destroys polychlorinated biphenyls (PCBs) found in painted structures or within the binding or caulking material on structures. It may be applied using a “paint-on and wipe-off” process that leaves the structure PCB-free and virtually unaltered in physical form.
