PNNL researchers develop new battery design for tracking salmon through rivers
AUNG THIHA's insight:
Graphene microbatteries for biotelemetry
"The battery has what's called a “jelly-roll” structure, in which layer after layer are laid on top of another and then rolled up into a cylindrical shape, like a jelly roll. The three layers are a separating material sandwiched on either side by a fluorinated graphene cathode and a lithium-based anode. This design enabled a significant increase in the surface area of the electrodes without increasing the overall size of the battery. Measurements indicate that the capacity of the material to store a charge is about double that of traditional microbatteries previously used in acoustic fish tags. The researchers claim that the battery can power a 744-microsecond signal sent every three seconds for about three weeks, or about every five seconds for a month. With these numbers, the researchers believe it’s the smallest battery with enough energy capacity to maintain that level of signaling."
(Medical Xpress)—Nanoparticles carrying a toxin found in bee venom can destroy human immunodeficiency virus (HIV) while leaving surrounding cells unharmed, researchers at Washington University School of Medicine in St.
It's not quite Rise of the Planet of the Apes, but it may not be too far off, either. By grafting human glial cells into the brains of mice, neuroscientists were able to "sharply enhance" their cognitive capacities.
LONDON (Reuters) - Scientists from a British cancer charity are teaming up with technology gurus from the likes of Amazon, Facebook and Google to design and develop a mobile game aimed at speeding the...
From a spit test for cancer to a shot that helps your body re-grow nerves along your spinal cord, these new advances in the world of medicine blur the line between biology and technology—to help restore, improve and extend our lives.
The first bionic hand that allows an amputee to feel what they are touching will be transplanted later this year in a pioneering operation that could introduce a new generation of artificial limbs with sensory perception.
