Got the time?
Plant cells signal between each other in order to agree what time it is.
Is a bottle of morning milk at night the equivalent of turning on all the lights at bedtime?
Breast milk contains ingredients in concentrations that change over the course of the day. Researchers think milk is chrononutrition, carrying molecular messages to help set a baby's internal clock.
Sikhumbuzo Notshe of the Stormers (L) is tackled by Waisake Naholo of the Highlanders (R) during a Super Rugby match between New Zealand’s Highlanders and South Africa’s Stormers.
Travel is commonly perceived as "the" major factor affecting a team's performance.
How many times do you hit snooze before getting out of bed?
You are tired. Would nine more minutes really hurt? Is hitting the snooze button a good idea? Should you just get out of bed? Or is snoozing a sign of a more serious medical issue?
Can’t sleep: these cloned macaque monkeys are missing a gene involved in regulating the sleep/wake cycle.

Researchers in China have produce a world first: gene edited, cloned macaque monkeys. They say such animals will be vital for research on human health – but ethical concerns remain.
Our study found that the performance of “night owls” and “morning larks” varied considerably on both cognitive and physical tasks.
The old saying 'the early bird catches the worm' might be especially fitting when it comes to peak mental and physical performance.
The circadian rhythm is present in every single cell of your body, guided by the central clock that resides in the brain.
Everybody has a personal internal clock in their brain that dictates when we feel like eating, waking and sleeping. But what happens when our life doesn't match our body clock? And how do we read it?
You've heard the adage, you are what you eat. But a new study suggests that you are 'when' you eat may be more accurate. Restricting eating times can keep chronic diseases at bay and ward off obesity.
When you eat is as important as what you eat. The mounting evidence for chrononutrition.
Largest study to date finds link between disturbed circadian rhythm and mood disorders.
Circadian clocks regulate the timing of hundreds of processes in the cell, suggesting that matching medications with your biological clock could improve the outcome
Children need different amounts of sleep but should aim to wake feeling rested, without an alarm.
The shift from daylight saving time will leave kids' body clocks an hour "out of sync", in a similar way to jet lag. Here are some evidence-based strategies to deal with this.
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.
