FCC reveals additional details of its plan to blanket the country with broadband

BY:sammy 10 hours ago on Technology      

About a third of all Americans still lack broadband access to the Internet. At its Digital Inclusion Summit, held Tuesday in Washington, D.C., the Federal Communications Commission (FCC) provided a preview of its upcoming National Broadband Plan (NBP) to provide high-speed Internet access to the estimated 93 million people in the U.S. without it. The plan, mandated by Congress last year as p Read More

TB or Not TB?: Novel Detector Could Shorten Testing Times, Aid Treatment Efforts

BY:eminaaron 10 hours ago on Technology      

Tuberculosis is a serious public health challenge in the developing world, where the infection claims roughly two million lives each year, according to the World Health Organization (WHO) . Yet the disease, which is a leading killer of patients with HIV/AIDS, is cumbersome to detect, resulting in delayed or inappropriate treatment, greater spread of the infection and preventable deaths.

A need for new nukes? "Modular reactors" for energy attract interest

BY:jimbo 2 days ago on Technology      

The entire budget of the U.S. Department of Energy branch that covers today's energy mix--from cleaning up energy generation's environmental aftermath to energy efficiency programs and renewable energy development--is $10 billion. That's enough to "either build one supercollider on the basic end or one nuclear power plant on the applied end," said Kristina Johnson, the undersecretary i Read More

Seeing the Little Picture: Novel Nanocoating Gives Atomic Force Microscope Users a Better Look at Individual Molecules

BY:kathy 2 days ago on Technology      

Spotting a disease in its earliest stages can help to facilitate its treatment greatly, yet telltale clues are often hidden at a scale too small to study accurately. This hindrance has some researchers looking for ways to use high-powered atomic force microscopes (AFMs) to study individual molecules for disease markers [More] Atomic force microscope - Molecule - Microscope - Instr Read More

Can solid oxide fuel cells like the Bloom box remake the energy landscape?

BY:kathy 4 days ago on Technology      

The fuel cell has a long history. Various types of fuel cells have been part of the NASA space program, and the basic science of how fuel cells work--an energy carrier comes in, creates a flow of charge in the anode, which migrates to the cathode, creating a current, and separated by some form of electrolyte--has been known for more than a century. Yet, Bloom Energy believes the time is finall Read More

Impact Factor: Can a Scientific Retraction Change Public Opinion?

BY:sammy 6 days ago on Technology      

When science revises its stance, the field itself follows established protocol to adapt, but public opinion can be slow to catch up. Rather than wiping the slate clean, last month's retraction of a key paper proposing a link between childhood vaccines and autism seem only to have widened the societal divide on the issue. And the rising rate of retractions--roughly ninefold between 1990 and 2008 Read More

Sound Idea: Acoustic Technology Lets Small Planes "Listen" for Nearby Aircraft

BY:jamms 6 days ago on Technology      

 Dutch and U.S. researchers are testing new acoustics technology that could be mounted on the outside of small aircraft, listening for characteristic sounds that indicate the presence of other fliers. Called an acoustic vector sensor (AVS), the system uses nanoscale materials to alert pilots to other aircraft within about 10 kilometers, a system that may help prevent midair collisions such a Read More

Could Mini Labs and Plant-Based Vaccines Stop the Next Pandemic?

BY:jamms 8 days ago on Technology      

The H1N1 virus's rapid spread worldwide last year exposed the weaknesses in the global system for swiftly developing, manufacturing and distributing vaccines for newly identified strains of influenza. In Texas, researchers are attacking the first two of these problems through Project GreenVax , which will use a plant-based approach to vaccine development and a modular manufacturing environment Read More

Can greener gadgets save us from e-waste?

BY:jimbo 10 days ago on Technology      

One laptop per child seems a simple slogan, chock full of benefit. What could go wrong when you put the power of the Internet and solar cells into the hands of children in the developing world? After all, not only does it train the global underclass in the tools of modern production, it also unleashes a creativity that may allow them to leapfrog the old, dirty, industrial development that ha Read More

Will the Internet make us stupider?

BY:amy 14 days ago on Technology      

Few observers, in 2000, would have foreseen Facebook being a ubiquitous presence on the Internet in 2010. Even fewer would have felt comfortable predicting whether some phenomenon like it would be “good" or bad” for human interaction, or for society's use of the English (or any other) language, for that matter. Undaunted by the perils of prognostication, the Pew Research Center' Read More
