Everyone has their own daily rhythm of digital activity, shows study

On October 8, 2015, Posted by , In Buzz, By ,,,,,,, , With No Comments

Over the past decade, there has been a surge of scientific studies on the digital activity of people, such as making mobile calls, texting, e-mailing, and posting on social media. Because nearly all human behavior leaves a digital footprint, scientists can use such digital activity as a proxy to track…

Cell's waste disposal system regulates body clock proteins

On October 7, 2015, Posted by , In Buzz, By ,,,,,,, , With No Comments

New way to identify interacting proteins could identify potential drug targets Rhythmic expression of key genes is essential for maintaining proper timekeeping of the body’s clock. In addition, rhythmic degradation of clockwork proteins is also crucial. However, surprisingly, researchers know little about these specific processes. A new Penn-led…

Scientists discover body clock switch

On October 5, 2015, Posted by , In Buzz, By ,,,, , With No Comments

Circadian rhythms enable all living beings to coordinate with the daily cycle, but how the body clock keeps accurate time, or how its malfunction affects people with sleep disorders, is not fully understood. Now, scientists say that a molecular “phosphoswitch” may provide the key. New clues to the body clock…

Tick tock. Tick tock. A team of scientists from Duke-NUS Graduate Medical School Singapore (Duke-NUS) and the University of Michigan at Ann Arbor have discovered a molecular switch that regulates the body’s circadian clock and allows it to keep time. This switch could be a potential drug target to treat…

Molecular switch keeps the circadian clock running on time

On October 3, 2015, Posted by , In Buzz, By ,,,,,, , With No Comments

Circadian rhythms help everything from plants to humans coordinate with the daily light-dark cycle, but how this natural clock keeps accurate time, or why it goes awry in people with sleep disorders, is still under investigation. New findings, published October 1 in Molecular Cell, suggest that a molecular switch balances…

UCD researcher's findings may lead to therapeutic targets for heart diseases associated with obstructive sleep apnoea

Dr Silke Ryan, a University College Dublin (UCD) medical researcher, has delivered the flagship Cournand lecture at European Respiratory Society’s (ERS) 2015 international congress. The congress, the largest annual respiratory meeting in the world, took place earlier this week in Amsterdam, the Netherlands, and was attended by over 20,000…
