New blood test reveals body’s internal clock

A new blood test has been designed that can indicate the body’s internal clock in order to guide treatments and to improve health. The test is of potential use to the medical field as many diseases are linked to circadian misalignment.

Essential Science: Biological clocks and brain cancer treatment

Information is emerging about how our internal body clocks influence health and disease. A new study shows how circadian rhythms can help with cancer treatments, and that the time of treatment plays a critical role.

Temperature throws the body clock back and forth by one hour

New York - The internal body clock is finely tuned and disruptions are associated with a range of diseases, such as obesity, diabetes and heart disease (which is a concern for shift workers). Changes to temperature can also disrupt the fine balance.

Evening coffee readjusts your body clock

London - Drinking an amount of coffee equivalent to a double espresso three hours before going to sleep affects the body clock, sending it back by an hour. This has sleep implications.

How genes tune the internal body clock

The human body clocks are regulated by a type of molecule known as long non-coding RNA, according to new research. Understanding this promises new insights into human health.

Does the time we eat affect our health?

The ways in which the timing of eating can influence health is an area of debate. New research shows that the timing of meals affects the levels of lipids in the livers of mice.

High fat diet affects the body clock

Irvine - As well as other ill health effects, a new study shows that diets high in fat also alter circadian rhythms. This means that high fat diets can alter the body clock, leading to various sleep disruptions and body changes.

Do we have a stomach clock?

A science study suggests that the nerves in the stomach act as a circadian clock, limiting food intake to specific times of the day, and acting as a type of ‘stomach clock’.

Sleep, circadian rhythms and aging

Human sleeping and waking patterns are linked to the internal circadian clock that corresponds closely with the 24-hour cycle of light and darkness. New studies show that when the disruptions can lead to aging.

Severe depression linked to the body's clock

Michigan - New research suggests that patients with major depressive disorder appear to have a malfunctioning 'body clock'. This finding could lead to new types of treatment.

Does light or temperature affect the body clock?

Studies undertaken on fruit flies have shown how their body clocks are affected by changes in temperature. Fruit flies are often used to mimic studies in humans. The findings have implications for conditions like jet-lag.

Christmas indulgence can affect the ‘food clock’

San Francisco - Feeling a little tired and off-color after the Christmas excesses? One of the reasons may not be the simply the copious amounts of food and alcohol but rather the disruption to the body’s internal ‘food clock’.

NASA flight director's family now lives by Martian time zone

NASA flight director, David Oh, has taken his whole family to Mars - or more precisely synced their bodies with its time zone. Celebrating the Curiosity's landing, the clan of five rearranged their schedules to coincide with the red planet's clock.

Do plants have 'body clocks'? Why plants bloom in the spring

Edinburgh - Some recent scientific research suggests that, like people, plants have daily and seasonal rhythms. The results of the research, into a protein contained within many plants, could possibly lead to improvements for agricultural production.
