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.
Poor quality sleep may bolster a person's genetic susceptibility to asthma, potentially doubling their risk of being diagnosed with the condition, suggests a large UK Biobank study, published in the open access journal BMJ Open Respiratory Research.
Cold activates a cellular cleansing mechanism that breaks down harmful protein aggregations responsible for various diseases associated with aging.
A small nucleus in the brainstem called locus coeruleus (literally the "blue spot,") is the primary source of a major neuromodulator, norepinephrine (NE), an important mediator of the 'fight or flight' response in animals. However, very little is known about the local connections of this small albeit critically important group of neurons.
When it comes to oxygen, you can have too much of a good thing. Breathing air that contains higher levels of oxygen than the usual 21 percent found in Earth's atmosphere can cause organ damage, seizures, and even death in people and animals, particularly if it's in excess of the body's oxygen needs. Until now, however, scientists have mostly speculated about the mechanisms behind this phenomenon, known as oxygen toxicity, or hyperoxia.
The asthma medication theophylline can be used to treat the movement disorder ADCY5-related dyskinesia. A recent study conducted by Martin Luther University Halle-Wittenberg (MLU), University Medicine Halle, and the University of Leipzig Medical Center demonstrated this.
A tiny worm called the C. elegans is enabling scientists to explore the emerging theory that Parkinson's disease starts in the gut.
Whether we're night owls or morning larks, our body clocks are set by the sun. Theoretically, changing day length and light exposure over the course of the year could affect the duration and quality of our sleep.
The daily rotation of Earth and its yearly voyage around the Sun marks the natural rhythm of life on the planet.
Notalgia paresthetica-;a nerve disorder characterized by a persistent itch in the upper back-;is a common and underdiagnosed condition worldwide.
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.
Night owls may be looking forward to falling back into autumn standard time but a new study from the University of Ottawa has found Daylight Saving Time may also suit morning types just fine.
When exposed to starvation and stress, certain bacteria enter a dormant state in which life functions cease. These cells, known as spores, can resist punishing extremes of heat, pressure, and even the extreme conditions of outer space by entering a profound hibernation.
According to a recent study, brain cells with the same “birthdate” are more likely to connect into cooperative signaling circuits that perform a variety of tasks, including memory storage.
Scientists from the University of California, Irvine, have defined how the circadian clock impacts cell growth, metabolism, and tumor progression in a new study.
For backyard gardeners, mild droughts and water ban restrictions common during the summer months can be a cause for concern.
Science might be a step nearer to comprehending where consciousness is located in the brain. A new research study demonstrates the significance of particular types of neural connections in locating consciousness.
A team of researchers from Chula Faculty of Science in cooperation with the Faculty of Medicine, Khon Kaen University has developed the "Jelly Nata Probiotics" jelly drink made from pineapple to benefit the mental wellbeing of the elderly, add value to pineapple while also solving the oversupply of pineapples.
A research team discovered that interruption of a circadian clock gene may be implicated in the formation of autism spectrum disorder.
In a comprehensive study involving one of the largest-ever samples of post-mortem brains, scientists at the Lieber Institute for Brain Development, in collaboration with researchers at the Johns Hopkins School of Medicine and Bloomberg School of Public Health, have pinpointed significant differences in gene expression in two specific regions of the brains of hundreds of patients who had bipolar disorder.
Medicine has a broad repertoire of anesthetics at its medication allows patients to better endure painful treatments or even sleep through them.
