Sleep is a physiological behavior that is common in all animal species. It forms around one third of a human life. It is not known clearly the exact functions of sleep but it seems to be essential for survival as prolonged sleep deprivation leads to severe physical impairment followed by cognitive loss and eventually death.
A new analysis of the entire genetic makeup of more than 53,000 people offers a bonanza of valuable insights into heart, lung, blood and sleep disorders, paving the way for new and better ways to treat and prevent some of the most common causes of disability and death.
Researchers from the University of Minnesota Twin Cities College of Science and Engineering and Medical School have developed a unique head-mounted mini-microscope device that allows them to image complex brain functions of freely moving mice in real time over a period of more than 300 days.
In a new study published in JAMA Pediatrics, researchers at Children's Hospital Colorado have found that tetrahydrocannabinol (THC), the psychoactive component of marijuana, stays in breast milk for up to six weeks, further supporting the recommendations of the American Academy of Pediatrics, the American College of Obstetricians and Gynecologists and the Academy of Breastfeeding Medicine to abstain from marijuana use during pregnancy and while a mother is breastfeeding.
A new study has demonstrated how plants exploit their metabolism to identify time and know when to develop.
According to a recent study, sufficient rest during vacation time restored functions linked to DNA regulation in shift workers deprived of sleep.
Coffee, cola, or an energy drink: caffeine is the world's most widely consumed psychoactive substance. Researchers from the University of Basel have now shown in a study that regular caffeine intake can change the gray matter of the brain. However, the effect appears to be temporary.
A tiny population of neurons known to be important to appetite appear to also have a significant role in depression that results from unpredictable, chronic stress, scientists say.
How often a person takes daytime naps, if at all, is partly regulated by their genes, according to new research led by investigators at Massachusetts General Hospital (MGH) and published in Nature Communications.
Researchers at the University of Maryland School of Medicine (UMSOM) and their colleagues published a new analysis today in the journal Nature from genetic sequencing data of more than 53,000 individuals, primarily from minority populations.
The Institute for Scientific Information on Coffee (ISIC) published a new report today, titled 'Coffee and sleep in everyday lives', authored by Professor Renata Riha, from the Department of Sleep Medicine at the University of Edinburgh.
A typical trait of all stem cells is their potential to renew on their own; however, scientists are unsure about how this ability is sustaining throughout life.
A new study exploring the impact of repeated sleep loss during a simulated working week has found that consuming caffeinated coffee during the day helps to minimize reductions in attention and cognitive function, compared to decaffeinated coffee.
Just like us, many insects need a decent night's sleep to function properly, but this might not be possible if they have been exposed to neonicotinoid insecticides, the most common form of insecticide used worldwide, suggests research by academics at the University of Bristol.
In a large-scale study of Danish children and young people, researchers from Aarhus University have for the first time found genetic variants that increase the risk of nocturnal enuresis - commonly known as bedwetting or nighttime incontinence. The findings provide completely new insights into the processes in the body causing this widespread phenomenon.
Researchers at University of California San Diego School of Medicine, in collaboration with Dutch scientists, have found that certain metabolites -- small molecules produced by the process of metabolism -- may be predictive indicators for persons at risk for recurrent major depressive disorder.
On a late summer day in 1953, a young man who would soon be known as patient H.M. underwent experimental surgery.
As wind power generation becomes more important, experts in Australia are examining whether wind 'farm' turbine background noise in the environmental can affect sleep and wellbeing of nearby residents.
The cell membrane is the cell's outermost line of defense against SARS-CoV-2, the novel coronavirus responsible for COVID-19 disease.
When air quality worsens, either from the smoke and ozone of summer or the inversion of winter, most of us stay indoors. But for individuals experiencing homelessness, that's not always an option.
The question of sleep apnea as the risk factor for COVID-19 arose in a study conducted by the Turku University Hospital and the University of Turku on patients of the first wave of the pandemic.
