Beyond batteries: Storing power in a sheet of paper
...es into the body, Pushparaj said. The materials required
to create the paper batteries are inexpensive, Murugesan said, but the team has not yet developed a way to inexpensively mass produce the devices. The end goal is to print the paper using a roll-to-roll system similar to how newspapers are printed. ...

for the production of male hormones researchers have theorized that statins may reduce production of these hormones. A large, recent study found that men using statin drugs were at lowered risk of developing metastatic or fatal prostate cancer, espec...
