The findings suggest that over 6,000 genes – about 25 percent of the genome – help determine an individual’s [...]
Worms help Penn researchers explain the evolution of sleep
Hopefully they didn’t use gummies for the study.
The roundworm C. elegans, a staple of laboratory research, may be key in unlocking one of the central biological mysteries: why we sleep. Researchers at the University of Pennsylvania School of Medicine report in this week’s advanced online edition of Nature that the round worm has a sleep-like [...]
Synthetic DNA close to yielding new life forms
Scientists at LS9, Inc. hard at work
A recent recent article on The Washington Post went into detail about how the idea creating artificial life forms through artificial DNA may be soon turned reality. Up until recently, even the most advanced laboratories couldn’t really do much more than add a few extra genes to something [...]
Nasal spray may prevent sleepiness
This orangutan could probably use some
Coffee drinkers everywhere, rejoice! A nasal spray containing the naturally occurring hormone known as “orexin A” appears to reverse the effects of sleep deprivation in monkeys. These sleep deprived monkeys performed similarly to well-rested monkeys on cognitive tests, researchers said.
“Orexin A is a promising candidate to become a [...]
