Nano-Probes Stay Inside a Cell's Nucleus for Days
Researchers from the Lawrence Berkeley National Laboratory (LBL) have developed fluorescent and stable nano-probes which can stay inside a cell's nucleus for hours or even days. According to this
LBL news release, this will help biologists to better understand nuclear processes that evolve slowly, such as DNA replication, genomic alterations, and cell cycle control. This research was partially based on previous investigations about quantum dots. Now, the researchers want to tailor their quantum dots, which emit different colors depending on their sizes, to check specific chemical reactions inside nuclei, such as how proteins help repair DNA after irradiation.
Zopa: eBay for money
Zopa is a place where creditworthy consumers who'd like to borrow money can get together with other consumers who are happy to lend it to them. Cutting out the middleman, lenders set their own rate of return and choose which borrowers they want to lend to.
To reduce overall risk, an individual lender doesn't actually lend to an individual borrower; instead a lender lends money across at least fifty Zopa borrowers, and similarly a borrower borrows from a group of Zopa lenders.
