After a time-shift, mixed signals from the circadian clock

...lock requires several days to adjust. This results temporarily in bimodal patterns of electrical activity that are generated by the clock within the SCN. Because electrical activity is the output of the circadian clock, the findings suggest that after a significant shift in light schedule, the rest of the brain ...

Doing a spin with DNA

...unds the double-stranded DNA like a clamp and then temporarily cuts through one of the two DNA strands. The accumulated torsional forces in the DNA are then spun out around the intact strand. After a number of turns the topoisomerase ones again firmly grabs the spinning DNA and 'glues' (ligates) the broken stand...

It's electric: Cows show promise as powerplants

...rganisms where much of the food that a cow eats is temporarily held and is continuously churned until it can be completely digested. This liquid mass is what scientists call rumen fluid. The researchers collected the fluid through a cannula, a surgically implanted tube that leads directly from the cow's hide in...

They also report something that was unexpected: Water plays a key role in the process, by regulating how long the donated electron stays inside the damage site before returning to the photolyase molecule.

Team led by Carnegie Mellon University scientist finds first evidence of a living memory trace

They also found that honeybees lost their working memory of a re-enforced odor if they were cooled down and then revived, suggesting that the memory wasn't permanently stored.

Depression model leaves mice with molecular scar
