Universal Method For Detection Of Circadian State From Gene Expression

The first simple blood test to identify your body's precise internal time clock as compared to the external time has been developed by Northwestern Medicine scientists. The test, TimeSignature which requires only two blood draws can tell physicians and researchers the time in your body despite the time in the external world. For instance, even if it's 8 a.m. in the external world, it might be 6 a.m. in your body.

This is a much more precise and sophisticated measurement than identifying whether you are a morning lark or a night owl. They can assess a person's biological clock to within 1.5 hours Various groups have tried to get at an internal circadian time from a blood test, but nothing has been as accurate or as easy to use as TimeSignature.

Previously, measurements this precise could only be achieved through a costly and laborious process of taking samples every hour over a span of multiple hours. The study was published in the journal PNAS.

Astronauts Emergencies In Space Station

We’ve been looking up at the stars for centuries, but it’s only in the last few decades that we’ve been able to actually think about exploring them. Space is still one of the harshest environments that we’ve ever discovered colder than most people can imagine, with no oxygen and plenty of radiation to increase the risk of cancer and other dangerous diseases. When an emergency happens in space, there’s no one to come to the rescue. 

The History of Space Emergencies

There are plenty of emergencies for us to pick from in science fiction movies and novels, but there are harrowing incidents to pick from in the real world, too. First, let’s take a look at the history of space travel and outer space emergencies.
