Circadian Rhythm is the regular recurrence, in cycles of about 24 hours, of biological processes or activities, such as sensitivity to drugs and stimuli, hormone secretion, sleeping, feeding, etc. This rhythm seems to be set by a 'biological clock' which seems to be set by recurring daylight and darkness.
Dr Yin-Zheng Wang of the Chinese Academy of Sciences' Institute of Botany is the lead of the study team that discovered movement in the Chirita pumila stigma and established a link between the motion and water sensitivity.
A recent study supported by Tokyo Tech’s World Research Hub Initiative discovered that gene expression within the apicoplast, an organelle in the malaria parasite Plasmodium falciparum, is controlled by melatonin (the circadian signaling hormone) in host blood and intrinsic parasite cues via a factor called ApSigma.
University of Queensland-led research has revealed liver cells influence the body's internal circadian clock, which was previously believed to be solely controlled by the brain.
New research from a multidisciplinary team helps to illuminate the mechanisms behind circadian rhythms, offering new hope for dealing with jet lag, insomnia and other sleep disorders.
In space, the bone density of both the human astronauts and rodent variety decreases. Scientists published this study on April 19th, 2023, in the journal Cell Reports. It says that alterations to the gut microbiomes of space travelers may be linked to this bone loss.
The body’s biological clock is interfered with by abnormal sleep habits, such as those of night shift workers, which have been connected to lung health problems.
The daily rotation of Earth and its yearly voyage around the Sun marks the natural rhythm of life on the planet.
The first proof of 12-hour cycles of gene activity in the human brain is presented by researchers at the University of Pittsburgh School of Medicine in the United States.
The Neurobiology of miRNA team, headed by Davide De Pietri Tonelli of the Istituto Italiano di Tecnologia (IIT-Italian Institute of Technology), established a link between a family of small RNA molecules known as piRNAs and brain inflammation.
According to two studies conducted by researchers at Weill Cornell Medicine, the circadian clocks that keep the body and its cells synchronized to the 24-hour day-night cycle are severely disrupted.
According to a new study published May 24th, 2022, in the open-access journal PLOS Biology by Alena Sumová and coworkers of the Czech Academy of Sciences in Prague, genes within the fetus’s developing clock respond to rhythmic behavior in the mother during fetal development, first before the biological clock starts ticking on its own.
Researchers aim to learn more about circadian rhythms, which are the 24-hour internal clock cycles of sleeping and waking that happens in all species, including humans, plants, fungi, and bacteria.
According to research, the brain’s capacity to clear a protein closely associated with Alzheimer’s disease is tied to the circadian cycle.
Clemson researcher Chris Saski admits sending the University's iconic Tiger Paw to space aboard a SpaceX Dragon spacecraft is, quite literally, "an out-of-this-world experience."
What are the effects of eating during the nighttime instead of the daytime? New research, focused on a simulation of night shift work, may hold implications for people eating at atypical times -; like those experiencing jet lag, circadian rhythm sleep disorders, or who tend to sleep late during the weekends.
Almost all cells regulate their biological processes over a 24-hour period, otherwise called a cell's circadian rhythm. To do so, cells use a biological clock that cycles different genes on and off throughout the day and night.
Circadian clocks, which regulate most of the physiological processes of living beings over a rhythm of about 24 hours, are one of the most fundamental biological mechanisms.
Daily cycles in virtually every aspect of our physiology are driven by biological clocks (also called circadian clocks) in our cells.
Almost every living thing on Earth-;from bacteria to plants to people-;have a circadian rhythm, the biological clock that controls both physiology and behavior of organisms over a 24-hour period.
Whether intermittent fasting is called the 5:2 diet or the 16/8 method, celebrities swear that these eating regimens are a great way to lose weight. Fasting is now trendy, but real science backs up claims that fasting two days a week or restricting eating to an eight-hour window each day leads to weight loss.
