Where and when you form new memories affects where they are stored in the brain's hippocampus, which is the memory center in our brain, researchers at Ohio State University found in a new study. They saw evidence that a particular part of the hippocampus stores memories relative to time over durations of at least a month and space over distances of up to 30 km (18.6 mi).
"Ignorance is bliss," so the old saying goes, but who wouldn't give their brainpower a boost if they had the chance? By altering a single gene to inhibit the activity of an enzyme called phosphodiesterase (PDE4B), researchers have given mice the opportunity to see what an increase in intelligence is like. While many people would welcome such a treatment, the scientists say their research could lead to new treatments for those with cognitive disorders and age-related cognitive decline.
A head trauma can be difficult to diagnose and destroy a life years after the event. Being able to tell immediately if the force someone has suffered is sufficient to result in a traumatic brain injury can make all the difference in limiting the damage. A team from the University of Pennsylvania has developed a material that could one day be incorporated into headgear to instantly gauge the severity of blows and provide a clearly visible indication of injury.
If you offer someone "a penny for their thoughts," how good a deal might you be getting? A study conducted at the University of Leicester has sought to shed some light on the value of our brainpower, finding a single penny to be worth to precisely three hours, seven minutes and 30 seconds worth of thinking.
Fusion power can seem a bit like the last bus at night; it's always coming, but never arrives. MIT is working to change that with a new compact tokamak fusion reactor design based on the latest magnetic superconductor technology. The ARC (affordable, robust, compact) reactor design promises smaller, cheaper reactors that could make fusion power practical within 10 years.
Researchers have created printable solid-state batteries that can be printed in any conceivable shape and can be seamlessly embedded into a variety of surfaces. To demonstrate the technology, the scientists printed a working heart-shaped battery onto a cup, another onto a paper eyeglass and even one in the form of the letters "PRISS", all of which were capable of powering LEDs.
A suspect says it on every forensics TV show ... "Of course my
fingerprints were at their house, I delivered a package to them earlier
this week!" Soon, though, that excuse may not be enough. Using a new
technique, investigators could be better able to determine how many days
ago fingerprints were left at a crime scene.
Unlike most other sea creatures, sea lions use their forelimbs
instead of a tail for propulsion. They also leave virtually no wake as
they travel through the water. With an eye towards applying this design
to human technology, George Washington University professor of
mechanical and aerospace engineering Megan Leftwich has developed a
robotic sea lion flipper.
Scientists have developed a new hydrogel that stretches and contracts just like an artificial muscle. The team created an L-shaped object made out of the hydrogel and immersed it in a water bath. When the water’s temperature was varied, it slowly "walked" forward.
