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.

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.
Next time just work with your body clock.

Eighty percent of North Americans can no longer see the Milky Way at night. But the problem with light pollution isn't just about stargazing.

Saturated fats are linked to metabolic disorders and heart disease. That may be because thes fats make some cells lose track of time, causing inflammation.
A podcast on time: telling it, perceiving it, doing it and travelling through it.
New research suggests disrupted sleep patterns could have more impact on some measures of women's performance than men's.

It might be that teaching people to reframe their thoughts about winter can help them overcome seasonal affective disorder year after year.
Sleep problems often occur just before an episode of mental illness.
What your sleep patterns may say about your risk of developing mental illness.
