(Phys.org)—When humans eventually travel to the Red Planet, the voyage will be long and difficult. The simulated Mars500 mission showed that every detail must be planned, including diet and sleep. The findings will also benefit those of us who stay behind. http://phys.org/news277553314.html Space & Earth Wed, 16 Jan 2013 10:08:52 EST news277553314 In the first study of its kind, a team of researchers led by faculty at the Perelman School of Medicine at the University of Pennsylvania and the Baylor College of Medicine, has analyzed data on the impact of prolonged operational confinement on sleep, performance, and mood in astronauts from a groundbreaking international effort to simulate a 520-day space mission to Mars. The findings, published online-first in the Proceedings of the National Academy of Sciences, revealed alterations of life-sustaining sleep patterns and neurobehavioral consequences for crew members that must be addressed for successful adaption to prolonged space missions. http://phys.org/news276774913.html Space & Earth Mon, 07 Jan 2013 15:00:05 EST news276774913 Sex can trigger remarkable female responses including altered fertility, immunity, libido, eating and sleep patterns—by the activation of diverse sets of genes, according to research from the University of East Anglia. http://phys.org/news266598496.html Biology Tue, 11 Sep 2012 19:00:01 EST news266598496 How does a plant know when to sprout a leaf, fold its petals or bloom?

The proteins, CLOCK and BMAL1, bind to each other to regulate the activity of thousands of genes whose expression fluctuates throughout the course of a day. Knowing the structure of the CLOCK:BMAL1 complex will help researchers understand the intricacies of how this regulation is carried out and how mutations in each protein lead the biological clock to go awry. http://phys.org/news257694800.html Biology Thu, 31 May 2012 14:57:05 EST news257694800 (AP) -- British officials have given their word: "We won't read your emails." http://phys.org/news256551659.html Technology Fri, 18 May 2012 09:21:08 EST news256551659 The blind Mexican cavefish (Astyanax mexicanus) have not only lost their sight but have adapted to perpetual darkness by also losing their pigment (albinism) and having altered sleep patterns. New research published in BioMed Central's open access journal BMC Evolutionary Biology shows that the cavefish are an example of convergent evolution, with several populations repeatedly, and independently, losing their sight and pigmentation. http://phys.org/news246460362.html Biology Sun, 22 Jan 2012 19:00:01 EST news246460362 If your New Year's resolution was to get more exercise and you're slipping already how about a digital personal trainer? http://phys.org/news245693362.html Electronics Fri, 13 Jan 2012 17:10:01 EST news245693362 Wireless earpiece maker Jawbone is once again blending fashion and technology to help people make healthier choices with a little help from their beloved Apple gadgets. http://phys.org/news239518235.html Electronics Thu, 03 Nov 2011 05:50:47 EST news239518235 Combined with increasingly hectic work, school and extracurricular schedules, the advent of wireless technology has led to less quality time between parents and children.

Their study, which appears in the journal Current Biology, may shed light on how genetic makeup contributes to sleep variation and disruption in humans. http://phys.org/news221398785.html Biology Thu, 07 Apr 2011 12:40:11 EST news221398785 (PhysOrg.com) -- A sleepless night can make us cranky and moody. But a lesser known side effect of sleep deprivation is short-term euphoria, which can potentially lead to poor judgment and addictive behavior, according to new research from the University of California, Berkeley. http://phys.org/news220080247.html Medicine & Health Wed, 23 Mar 2011 06:24:36 EST news220080247 (PhysOrg.com) -- Scientists in Canada noticed pond snails spent around 10 percent of their time attached to the side of their tank with their tentacles partly withdrawn, their shells hanging away from their bodies, and with their feet symmetrical and relaxed. The researchers decided to do some experiments to find out if the snails were asleep or just resting, and their results provide the first evidence that gastropods sleep. http://phys.org/news217238192.html Biology Fri, 18 Feb 2011 07:56:51 EST news217238192 New research from Warwick Medical School published today in the European Heart Journal shows that prolonged sleep deprivation and disrupted sleep patterns can have long-term, serious health implications. Leading academics from the University have linked lack of sleep to strokes, heart attacks and cardiovascular disorders which often result in early death. http://phys.org/news216371815.html Medicine & Health Tue, 08 Feb 2011 07:30:04 EST news216371815 A study in the Dec. 1 issue of the journal Sleep found that deployment to Iraq and Afghanistan significantly influenced sleep quality and quantity in a population of 41,225 military service personnel.
