Tackling the brain's barrier (w/video)

The blood-brain barrier protects the brain so effectively that it also prevents helpful drugs and therapeutic agents from reaching diseased areas of the brain. And because scientists know very little about the blood-brain barrier, discovering ways to overcome the blockade has been a challenge.

Self-charging power cell converts and stores energy in a single unit

Researchers have developed a self-charging power cell that directly converts mechanical energy to chemical energy, storing the power until it is released as electrical current. By eliminating the need to convert mechanical energy to electrical energy for charging a battery, the new hybrid generator-storage cell utilizes mechanical energy more efficiently than systems using separate generators and batteries.

Space-time symmetry renders optical systems invisible

For the first time ever, physicists from Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have succeeded in proving that an optical system can be 'invisible' from one side and act like a mirror from the other side.

Batteries made from graphene could power tomorrow's electric cars

Engineering researchers at Rensselaer Polytechnic Institute made a sheet of paper from graphene and then zapped the paper with a laser or camera flash to blemish it with countless cracks, pores, and other imperfections. The result is a graphene anode material that can be charged or discharged 10 times faster than conventional graphite anodes used in today's lithium (Li)-ion batteries.

Scientists examine effects of manufactured nanoparticles on soybean crops

Sunscreens, lotions, and cosmetics contain tiny metal nanoparticles that wash down the drain at the end of the day, or are discharged after manufacturing. Those nanoparticles eventually end up in agricultural soil, which is a cause for concern, according to a group of environmental scientists that recently carried out the first major study of soybeans grown in soil contaminated by two manufactured nanomaterials.
