A Sleepy Science: Will Humans Hibernate Their Way Through Space? - Space.com  Biggiogera and his colleagues were able to create a hibernation-like state in cell cultures using a substance called DADLE, which has opium-like properties and is similar to a family of molecules produced in the human brain. In cells, DADLE reduced proliferation and the transcription of genetic material, effectively putting the cells to sleep. Biggiogera and his colleagues are now studying the effects of DADLE in laboratory rats, with results anticipated by the end of 2004.

Blaine's BMI was 21.6 when he emerged from the box - which would normally be classed as healthy - but it had fallen from 29.

Gene switch can 'turn off cancer'  - BBC  Myc controls cell division. Unlike the normal version of the gene, the modified version stayed permanently switched on, meaning cells were constantly dividing and some became cancerous. The researchers engineered mice so that the Myc gene could be switched off by a common antibiotic called doxycycline. Feeding the mice doxycyline turned the faulty Myc gene off so cancer growth was blocked. When the researchers stopped the doxycycline the mice developed aggressive liver cancer. Reintroducing doxycycline into their feed not only turned Myc back off, blocking further cancer growth, but it also turned the cancer cells back to normal.
