redOrbit Staff & Wire Reports - Your Universe Online A group of US pediatricians is encouraging middle schools and high schools to delay their start times by as much as an hour to avoid the physical and mental issues that can arise as a result of sleep deprivation. According to Andrew M. Seaman of Reuters Health, a new policy statement issued Monday by the American Academy of Pediatrics (AAP) said that schools should start no earlier than 8:30am, as previous research suggested that...

circadian rhythm
2014-08-21 03:00:40

UT Southwestern Medical Center Researchers at UT Southwestern Medical Center have found a new way that internal body clocks are regulated by a type of molecule known as long non-coding RNA. The internal body clocks, called circadian clocks, regulate the daily “rhythms” of many bodily functions, from waking and sleeping to body temperature and hunger. They are largely “tuned” to a 24-hour cycle that is influenced by external cues such as light and temperature. “Although we...

redOrbit Staff & Wire Reports - Your Universe Online Astronauts tend to suffer from a significant amount of sleep deficiency in the weeks leading up to liftoff and throughout the duration of their missions, the authors of a 10-year research project being hailed as the largest-ever analysis of sleep habits before and during space flight report in Friday’s edition of The Lancet Neurology. As part of the study, experts from the Brigham and Women's Hospital (BWH) Division of Sleep and...

Clone collection supports design of more robust plants for future food security LOS ANGELES, July 17, 2014 /PRNewswire-USNewswire/ -- Researchers have created the first comprehensive library of genetic switches in plants, setting the stage for scientists around the globe to better understand how plants adapt to environmental changes and to design more robust plants for future food security. The collection, which took more than 8 years and $5 million to create, contains about 2,000...

Sedentary Behaviors Keep Night Owls From Regular Exercise Routines
2014-06-04 08:14:54

Lawrence LeBlond for redOrbit.com - Your Universe Online A recent study published in the journal Evolutionary Psychology found that persons who stay up all night are bigger risk takers than those who get a regular night’s sleep. While that research looked at the financial aspect of taking risks, it is likely that another risky move associated with night owls is not getting regular exercise. A new study published in the journal Sleep, and to be presented June 4 in Minneapolis,...

FECYT - Spanish Foundation for Science and Technology A possible pharmacology objective for chemotherapy Patients receiving chemical treatment for cancer often suffer fatigue and body weight loss, two of the most worrying effects of this therapy linked to the alteration of their circadian rhythms. The circadian system, better known as our biological clock, is responsible for coordinating all the processes that take place in our organism. If it does not function correctly, what is...

Texas A&M AgriLife Communications A team of Texas A&M University System scientists have investigated how "body clock dysregulation" might affect obesity-related metabolic disorders. The team was led by Dr. Chaodong Wu, associate professor in the department of nutrition and food sciences of Texas A&M's College of Agriculture and Life Sciences, and Dr. David Earnest, professor in the department of neuroscience and experimental therapeutics, Texas A&M Health Science Center....

All organisms, from mammals to fungi, have daily cycles controlled by a tightly regulated internal clock, called the circadian clock. The whole-body circadian clock, influenced by the exposure to light, dictates the wake-sleep cycle. At the cellular level, the clock is controlled by a complex network of genes and proteins that switch each other on and off based on cues from their environment. Most genes involved in the regulation of the circadian clock have been characterized, but Akihiro...

Brett Smith for redOrbit.com - Your Universe Online Whether it’s during a hum-drum work trip or the vacation of a lifetime, jet lag can disrupt daytime activities and make sleeping at night extremely difficult. A new app based on previous research and mathematical modeling claims to cure or prevent jet lag in three days by guiding a traveler’s exposure to light. Described by a paper in the journal PLOS Computational Biology, the new program applies the concept of...

A Good Dose Of Morning Sunlight Keeps Off The Pounds: Study

Brett Smith for redOrbit.com - Your Universe Online By most accounts, a healthy lifestyle should include a balanced diet, regular exercise, and – according to a new study published in the journal PLOS ONE – a long dose of bright light in the morning. In the study, researchers from Northwestern University found that the time, strength and duration of light exposure is directly linked to body mass index (BMI), even after considering confounding factors. "The earlier this light...
