Scripps research scientists model 3D structures of proteins that control human clock
In an Early Edition issue of The Proceedings of the National Academy of Sciences (PNAS) on April 9, 2009, the researchers report that they have been able to determine the molecular structure of a plant photolyase protein that is surprisingly similar to two cryptochrome proteins that control the "master clock" in humans and other mammals. view more (2009-04-13)
Plants grow bigger and more vigorously through changes in their internal clocks
Hybrid plants, like corn, grow bigger and better than their parents because many of their genes for photosynthesis and starch metabolism are more active during the day, report researchers from The University of Texas at Austin in a new study published in the journal Nature. view more (2008-11-24)
Researchers lay out vision for lighting 'revolution'
A "revolution" in the way we illuminate our world is imminent, according to a paper published this week by two professors at Rensselaer Polytechnic Institute. view more (2008-12-19)
Sodium, prostaglandin may be keys to successful treatment for some bedwetters
Children with a form of bedwetting that does not respond to a common medication have more sodium and urea in their nighttime urine, possibly because of an imbalance of prostaglandin, a hormone-like substance, a new study has found. view more (2006-12-01)
Heart rhythm genes possible factors in SIDS
Nearly 10 percent of sudden infant death syndrome (SIDS) victims have mutations or variations in genes associated with potentially lethal heart rhythms (arrhythmias), according to two newly published studies involving Vanderbilt researchers. view more (2007-01-16)
Body clock linked to diabetes and high blood sugar in new study
Diabetes and high levels of blood sugar may be linked to abnormalities in a person's body clock and sleep patterns, according to a genome-wide association study published today in the journal Nature Genetics. view more (2008-12-08)
Insights into activity-dependent neuronal growth through RSRF-supported research
Brain-derived neurotrophic factor (BDNF) has been a subject of keen interest in neuroscientific circles for several years, turning up in studies of conditions ranging from central hypoventilation syndrome to obsessive-compulsive disorder, depression, bipolar disorder and schizophrenia - a range of disorders uncannily parallel to those produced by... view more...

Acute Sleep Deprivation Leads To Changes In Nighttime Urine
Our body's production of urine follows a circadian rhythm. During the day, we experience greater urinary frequency; at night, urine production declines, enabling us to get uninterrupted sleep. view more (2007-08-09)
To sleep, perchance to dream: New insight into melatonin production
In the April 1 issue of G&D, a Korean research team led by Dr. Kyong-Tai Kim (Pohang University) describes how melatonin production is coordinated with the body's natural sleep/wake cycles. view more (2007-04-02)
New studies on cancer and schizophrenia, depression and heart disease, trauma and autism
The 2007 American College of Neuropsychopharmacology Annual Meeting will feature hundreds of new studies on brain and behavior from the world's leading scientists. Presentations include innovative research on potential new treatments for depression, post-traumatic stress disorder, autism and addiction. view more (2007-12-11)
TAU Researchers Discover Correlation Between Birth Month and Short-Sightedness
Planning for a summer delivery for your child? You might want to choose an ophthalmologist along with an obstetrician. view more (2007-08-27)
Not just humans benefit from animal biotechnology
Laboratory animals are the source of major discoveries and breakthroughs in biology, not just in tackling disease but also unravelling fundamental molecular processes. Delegates at a recent research conference organised by the European Science Foundation (ESF) and Wellcome Trust heard how technology capable of analysing animal genes across the... view more...

Reciting Ave Maria linked to a healthy heart
Reciting the rosary prayer or yoga mantras enhance some aspect of heart and lung function and might be viewed as a health practice as well as a religious practice, finds a study in this week's Christmas issue of the BMJ. view more (2001-12-19)
The first autism disease genes
The autistic disorder was first described, more than sixty years ago, by Dr. Leo Kanner of the Johns Hopkins Hospital (USA), who created the new label 'early infantile autism'. view more (2008-09-02)
Caltech researchers pinpoint neurons that control obesity in fruit flies
A team of scientists from the California Institute of Technology (Caltech) have pinpointed two groups of neurons in fruit fly brains that have the ability to sense and manipulate the fly's fat stores in much the same way as do neurons in the mammalian brain. view more (2009-08-19)
Gene that makes people 'early to bed and early to rise' demystified
The recent discovery that a mutant "clock" gene made some people "early to bed and early to rise," a condition known as familial advanced sleep phase syndrome (FASPS), offered one of the first glimpses into the genetic basis of sleep in humans. view more (2007-01-12)
No evidence that melatonin is effective in treating jet lag
There is no evidence that melatonin is effective in treating secondary sleep disorders or preventing jet lag, finds a study published online by the BMJ today. view more (2006-02-10)
Why missing out on a good night's sleep could give you ulcers
Missing out on a good night's sleep through long haul travel, shift work, or partying could increase the risk of ulcers. Research in Gut shows that levels of a chemical, produced by the stomach and small intestine to repair tissue damage, are highest at night, and are suppressed after a meal. Twelve healthy, 20 to 24 year old non-smokers were... view more... (2001-04-10)
Increase in childhood leukaemia may be part due to increased light at night
London, UK: International experts will (Wednesday 8 September) consider the evidence for a link between the rise in childhood leukaemia and increased light at night at an international scientific conference in London. The incidence of childhood leukaemia increased dramatically in the twentieth century. The increase has mainly affected the under... view more... (2004-09-06)
The hormone of darkness: melatonin could hurt memory formation at night
What do you do when a naturally occurring hormone in your body turns against you? What do you do when that same hormone - melatonin - is a popular supplement you take to help you sleep? A University of Houston professor and his team of researchers may have some answers. view more (2007-11-16)
