Science shows that early starts can be bad for teenagers' health. Schools and universities would be better off starting at 10am.
Salting streets in Milwaukee.
A recent study shows plankton that have adapted to road salt have disrupted circadian rhythms. This finding suggests that environmental pollutants could also affect human circadian clocks.
Getting enough sleep can help our memory, waistline and our performance at work.
If you need an alarm to get up in the morning, you're probably not getting enough sleep.
We’re less able to burn fat and process carbs at night.
It comes down to what and how much you eat over the day, rather than when you eat most of your food.
Waking up is hard to do.
It's normal to feel a bit groggy when you wake up – parts of your brain are still asleep.
Managing sleep and time zones can take the fun out of Christmas travel.
Step-by-step travel tips - including how to use those fancy blue light goggles - if you're travelling East to West, or West to East these holidays.
Children with an irregular bedtime performed worse on cognitive tests, had worse behaviour and were more likely to be obese than others.
Though not this obvious from the outside, plants are keeping time.
Precisely calibrated timekeepers are found in organisms from all domains of life. Biologists are studying how they influence plant/pathogen interactions – what they learn could lead to human medicines.
There may be a very good reason for not wanting to get up in the morning when it’s still dark.
Evidence for a link between breast cancer and artificial light appears to be growing. Do studies showing higher risk of breast cancer the farther west a woman lives in a time zone add to the science?
Biological clocks set the pace for nearly all living things, and Jeffrey Hall, Michael Rosbash and Michael Young – awarded the Nobel Prize in Physiology or Medicine – helped us understand how.
‘The key fourth awardee here is … the little fly,’ Hall said.
Americans Jeffrey Hall, Michael Rosbash and Michael Young share the 2017 Nobel Prize in Physiology or Medicine for work that explained how our cells keep track of time.

The winners of the Nobel Prize in Physiology or Medicine discovered how our internal body clock works.
Bad night’s sleep? Blame your genes.

Whether you're a night owl or a morning lark, circadian rhythms control just about every aspect of your health.
Artificial light has transformed the night sky, a change researchers continue to link to health problems.
Fabio Falchi et al
Study uses satellite data to add to growing evidence that nighttime light exposure raises risk of breast cancer, with the strongest link among young women.
Color-changing cells in an Atlantic squid’s skin contain light-sensitive pigments.
We're used to thinking of our eyes detecting light as the foundation of our visual system. But what's going on in other cells throughout the body that can detect light, too?
How to eat yourself brighter.
All parents have probably struggled to get their kids to sleep at some point. This is even more difficult when a child has ADHD.
Children with ADHD are much more likely than other kids to struggle getting to sleep, and staying asleep. Up to 73% of Australian parents report their child with ADHD has problems sleeping.
Micro changes have macro results.

New research suggests our gut microbes have their own circadian rhythms that in turn influence our organ functions. Is this an explanation for how disrupting our daily patterns can cause health problems?
Time to get up.

Gaining a better sense of what genes are involved in regulating circadian clocks could put us on a path to find better treatments and therapies to help people adjust to time shifts.
What colour is your light?
The wrong kind of light can seriously impact your well-being.
