"In the best world, evening people should just get up later and work later to better live in agreement with their own biological rhythm," he says.

But even if you sat in a dark room all day, your biological rhythm and your circadian rhythms would still run—our brains have a kind of internal clock to mediate this.

"(The three scientists') discoveries explain how plants, animals, and humans adapt their biological rhythm so that it is synchronized with the Earth's revolutions," the Nobel Assembly at Sweden's Karolinska Institute said in a statement.

The laureates used fruit flies to isolate a gene that controls the normal daily biological rhythm and showed how this gene encodes a protein that accumulates in the cell during the night and degrades during the day.

Dr. Hall, Dr. Rosbash and Dr. Young were "able to peek inside our biological clock," helping "explain how plants, animals and humans adapt their biological rhythm so that it is synchronized with the Earth's revolutions," the Nobel Prize committee said.

Then, in the mid-1980s, the three laureates used fruit flies to isolate a gene called period that controls the normal daily biological rhythm and showed how it encodes a protein called PER that accumulates in cells during the night and degrades during the day.

Studies of shift workers, who work unusual hours and live out of sync with their normal biological rhythm, show that they are at increased risk for heart disease, ulcers, depression, obesity and certain cancers, as well as a higher rate of workplace accidents and injuries due to a slower reaction rate and poor decision-making. 8.

There are perks to steering clear of your smartphone or skipping TV in the evening: you automatically go to sleep sooner because the artificial light doesn't keep you awake (or perhaps you just fall asleep because you have nothing to do?)Our body follows a biological rhythm that's centered around daylight and this rhythm can vary from person to person — and even from animal to animal and plant to plant.

The 2017 Nobel Prize in physiology or medicine has been awarded to Jeffrey Hall, Michael Rosbash and Michael Young for their work on the genetic and cellular mechanisms that govern biological clocks and circadian rhythms, per AP. "Their discoveries explain how plants, animals and humans adapt their biological rhythm so that it is synchronized with the Earth's revolutions," said Thomas Perlmann, secretary of the Nobel Committee for Physiology or Medicine, when he announced the prize.

It has been suggested that, like the 24-hour circadian rhythm, the body also has a yearly "circannual" biological rhythm. Vaiserman et al. have suggested that the climatic conditions at birth act as a zeitgeber that triggers internal stress and increases the chance of death.

The biological rhythm can vary from nocturnal in smaller lemurs to diurnal in most larger lemurs. Diurnality is not seen in any other living strepsirrhine. Cathemerality, where an animal is active sporadically both day and night, occurs among some of the larger lemurs. Few if any other primates exhibit this sort of activity cycle, either regularly or irregularly under changing environmental conditions.

Early growth response protein 3 is a protein in humans, encoded by the EGR3 gene. The gene encodes a transcriptional regulator that belongs to the EGR family of C2H2-type zinc-finger proteins. It is an immediate-early growth response gene which is induced by mitogenic stimulation. The protein encoded by this gene participates in the transcriptional regulation of genes in controlling biological rhythm.

To be called circadian, a biological rhythm must meet these three general criteria: # The rhythm has an endogenous free-running period that lasts approximately 24 hours. The rhythm persists in constant conditions, (i.e., constant darkness) with a period of about 24 hours. The period of the rhythm in constant conditions is called the free-running period and is denoted by the Greek letter τ (tau).

In its simplest form, this refers to two neurons capable of rhythmogenesis when firing together. The generation of a biological rhythm, or rhythmogenesis, is done by a series of inhibition and activation. For example, a first neuron inhibits a second one while it fires, however, it also induces slow depolarization in the second neuron. This is followed by the release of an action potential from the second neuron as a result of depolarization, which acts on the first in a similar fashion.

In 2005, Kondo succeeded in reconstituting the circadian oscillation of cyanobacterial kaiC phosphorylation in vitro. Kondo's seminal 2005 discovery was the first example of a recapitulated biological rhythm in a test tube, mimicked rhythms observed in eukaryotic cells, and disproved the universal necessity of the transcription-translation autoregulatory feedback loop. Kondo's characterization of kaiABC behavior provided a molecular mechanism by which proteins respond to changes in time and enabled the fields of bacterial genetics and quantitative biochemistry to aid investigation of the biological clock.

Biological Rhythm Research is a peer-reviewed academic journal that publishes articles about research into the broad topic of biological rhythms. The areas covered range from studies at the genetic or molecular level to those of behavioural or clinical topics involving ultradian, circadian, infradian, or annual rhythms. The journal publishes original scientific research papers, review papers, short notes on research in progress, book reviews and summaries of activities, symposia and congresses of national and international organizations dealing with rhythmic phenomena. The current editors are W. J. Rietveld, A. A. Putilov, and D. Weinert.

Domesticated guinea pigs thrive in groups of two or more; groups of sows, or groups of one or more sows and a neutered boar are common combinations, but boars can sometimes live together. Guinea pigs learn to recognize and bond with other individual pigs, and testing of boars shows their neuroendocrine stress response is significantly lowered in the presence of a bonded female when compared to the presence of unfamiliar females. Groups of boars may also get along, provided their cage has enough space, they are introduced at an early age, and no females are present. Domestic guinea pigs have developed a different biological rhythm from their wild counterparts, and have longer periods of activity followed by short periods of sleep in between.

In 2008, Truman went on to discover that eclosion rhythms, which are mediated by the circadian release of the neurohormone EH, can be masked. In chronobiology, masking refers to the apparent coupling of an observable biological rhythm with an external environmental time cue, without affecting the underlying circadian clock that mediates the observed rhythm. Truman and colleagues observed increased eclosion in adult Drosophila flies immediately following a lights-on signal, which lead to their subsequent discovery that light triggers rapid eclosion in Drosophila on the condition that there was prior EH release. This occurs through the convergence of parallel neurosecretory pathways, both of which are activated by EH. These two EH activated pathways oppose each other; one is an excitatory behavioral pathway and one is inhibitory.

The Tropenhaus () in Frutigen, Switzerland, is a commercial project using geothermal energy from hot water flowing out of the Lötschberg base tunnel for the production of exotic fruit, sturgeon meat, and caviar in a tropical greenhouse in the Swiss alps. In 2007, the project received the Prix Evenir, the Swiss petroleum industry's CHF 50,000 award for sustainable development. The idea for the greenhouse began in 2002 when it became apparent that the water continuously flowing out of the Lötschberg Base Tunnel could not be directly diverted to the local river, the Kander, as its temperature of would disrupt the biological rhythm of the endangered trout there. Rather than cooling the water artificially, wasting its thermal energy, tunnel engineers founded a start-up company to use the warm water to heat a greenhouse.
