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.
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.
Scientists say naked mole rats - a rodent native to West Africa - may hold the key to new treatments for degenerative diseases such as cancer and dementia.
Several biological processes are subject to rhythmic variations. Popular examples of this include the supposed circadian rhythm.
News-Medical speaks to Dr. Beheshti from NASA about his latest research that investigated whether changes in mitochondria could cause health problems in Space.
Researchers have identified a new protein that makes it possible to repair DNA. The protein in question is called cryptochrome.
Irina Shtangeeva is a researcher at the Department of Soil Science and Soil Ecology, St Petersburg University. She has studied the ability of wheat and couch grass to accumulate toxic substances.
A new study from McGill University shows that increases in the concentrations of blood sodium can have an influence on the biological clock of mice, opening new research avenues for potentially treating the negative effects associated with long-distance travel or shift work.
As the world wrestles with the coronavirus (COVID-19) pandemic, which arose after the virus jumped from an animal species to the human species, University of Delaware researchers are learning about new ways other pathogens are jumping from plants to people.
Older men who have a weak or irregular circadian rhythm guiding their daily cycles of rest and activity are more likely to later develop Parkinson's disease, according to a new study by scientists at the UC San Francisco Weill Institute for Neurosciences who analyzed 11 years of data for nearly 3,000 independently living older men.
Researchers analyzed 13,000 tumors, highlighting two formerly overlooked genes as promising new therapeutic targets for treating cancer.
