Fun Science FRIEDay – Cell Hijack!

Happy Fun Science FRIEDay!!

This week we bring you work from researchers at the Massachusetts Institute of Technology (MIT), where they discovered a new method to “hijack” cells. Think about it, if we could make our own cells do our bidding, we could reprogram them to do all sorts of wonderful things for us, such as manufacture insulin, attack tumors, etc. But hijacking a cell is no easy venture. In nature viruses can be quite efficient at hijacking cells, and because of this current methods employed by researchers to hijack cells entails penetrating the cell’s wall with a virus. The biggest issue with this method is that it tends to inflict permanent damage on cell.

Fun Science FRIEDay – Fasting Fights Cancer?

Happy Fun Science FRIEDay to everyone. FSF is back and with a new name!

After a brief hiatus to sort out some legal issues regarding the title of FSF, and a trip to the World Cup, I am hopefully back into the swing of providing you with mostly weekly, fun, and interesting science facts!

Up this week is cancer, and what we as a species are doing to kick its ass! … along w/ the involuntary help of the Mus musculus species.

Relatively recent work by Dr. Longo, of the University of Southern California, and his colleagues, has shown that a simple dietary adjustment may help combat the negative influence of chemotherapy and age on immune cell function! In short, their findings suggest that fasting, yes you heard right, FASTING, may provide benefits for cancer patients and the elderly by replenishing stem cells in the blood.
