Smart Defense: NFL Fans Will Help Test Earthquake Warning System
Tune in to a Seattle Seahawks game this NFL playoff season. Seismologists will be tracking the shimmies and shakes of Seattle's CenturyLink Field in order to test their earthquake early-warning system. "It's a silly experiment that gives us a chance to work on our equipment," said John Vidale, a professor at the University of Washington and director of the Pacific Northwest Seismic Network (PNSN). Vidale and his colleagues at the U.S. Geological Survey and other universities are developing a system called ShakeAlert, with the goal of giving residents in earthquake-prone areas a few seconds' warning before potentially deadly shaking starts.

Lizard Penises Evolve at Super-Speed
The study is the first to directly measure the evolution rate of the penis of any species, though researchers have long suspected that the male genitalia evolve faster than other body parts, said study researcher Julia Klaczko, a biologist at the University of Campinas in Brazil. "What we see is, sometimes, very close species have very different hemipenes or genitalia," Klaczko told Live Science. Hemipenes are the pair of organs that make up the version of a penis found in snakes and lizards. Anolis lizards are a well-studied group, and researchers have lots of information about the relationships between the species, as well as their habitats and body shapes, Klaczko said.

Japan reorients space effort to bolster security, drive exports
TOKYO (Reuters) - Japan is shifting its space program toward potential military uses in a new policy hailed on Friday as a "historic turning point" by Prime Minister Shinzo Abe, who wants to strengthen defence and boost exports. The move comes as emerging powers such as China and India join the United States to expand space activities for commercial and security purposes. Last year, Abe eased a postwar curb on arms exports and on allowing troops to fight overseas, as part of a more robust military and diplomatic posture for Japan. ... Read More »

10,000 Steps? New Trackers Go Beyond the Data Dump
"Lots of data from our wearables and beyond is just data," said Dr. Daniel Kraft, a pediatrician and the founding executive director of Exponential Medicine, at a talk here at the 2015 CES. For example, a wearable device called StoneCrysus, which will be available in February 2015, says it can calculate people's metabolic rate based on measures like their heart and respiration rates. StoneCrysus allows users to track the food they're eating with a user-friendly picture of their meal— they can place portions of common foods on an image of a plate, said Dr. David Landers, a cardiologist and co-founder of the Edgewater, N.J., company that makes the device.

Magnetic Pulses May Reboot Stroke Recovery (Op-Ed)
More than 750,000 Americans experience a stroke each year in the United States. When one side of the brain is damaged by stroke, the healthy side tends to generate much more activity to compensate for the immobile side. Often, stroke patients can have a rapid partial recovery in the first few months after a stroke, then the spontaneous healing process slows down after about three to six months, and then slows even further after a year. Up to this point, doctors have not known how to reset the brain back into the state of rapid recovery that we see in the initial months after a stroke. Read More »

The role of inflammatory cytokines as key modulators of neurogenesis
Neurogenesis is as a complex neurobiological process by which new neurons are generated from neural stem cells (NSCs) [1]. The ability of stem cells to self-renew and then differentiate into specific cell subtypes has been demonstrated both in vitro [2] and, more recently, in vivo [3]. For this reason, the term 'neural progenitor cells' (NPCs) is now used to loosely define all dividing cells with some ability to generate different neural units [3]. Current data have estimated that approximately 700 new neurons are added to the adult human hippocampus daily, suggesting that adult hippocampal neurogenesis has a critical role in mediating human brain functions, such as memory formation and cognition [4,5].
