U.S. Soil Grows Wind Power Garden
by Michael Keller
Wind farms have proliferated across the American landscape over the last four decades. According to the U.S. Energy Information Administration, one wind farm existed California in 1975. It produced enough electricity to power around 4,100 homes. By 2012, 815 wind farms were pumping out enough power for 15 million homes.

A PET Prototype
This device from the 1960s is an early prototype of a positron emission tomography (PET) scanner. Scientists at the Department of Energy’s Brookhaven National Lab built this circular version of the PET scanner to image small brain tumors and nicknamed it the Head-Shrinker.
PET scans work after radioisotope tracers are introduced into the patient. The imaging equipment picks up gamma rays emitted as a result of the isotope’s decay. The system allows for functional imaging of processes throughout the body. The device is now used for research and to diagnose certain cancers, brain diseases and heart problems.[[MORE]]

Are Focused Sound Waves Medicine’s Next Big Thing?

by Michael Keller

The pictures on the left above show a patient with a benign bone tumor called an osteoid osteoma. The images on the right show the patient after doctors treated the tumor with focused ultrasound, a therapy that delivers high frequency sound waves inside the body without surgery.

Advocates for the technology say it is proving to be a useful and cost-effective treatment for a number of afflictions, from various cancers to neurological diseases.

“Focused ultrasound is increasingly being considered a game-changing technology,” said Kim Butts Pauly, a Stanford University professor of radiology.

Software Accurately Predicts Faces As Babies Age Over Lifetime

Computer scientists can now predict how a person’s face ages from a baby to an older adult.

University of Washington researchers have developed software that automatically morphs a face through a lifetime of growing and changing no matter the lighting, expression or pose of the subject in the starting picture.

“Aging photos of very young children from a single photo is considered the most difficult of all scenarios, so we wanted to focus specifically on this very challenging case,” said study coauthor Ira Kemelmacher-Shlizerman, an assistant professor of computer science and engineering, in a university statement. “We took photos of children in completely unrestrained conditions and found that our method works remarkably well.”

See a comparison of their morphing software and the real person at different ages below.
