Early to bed, early to rise
In an upcoming G&D paper, a team of German scientists presents a genetic basis for understanding human morning lark behavior. Dr. Achim Kramer (Charité Universitaetsmedizin Berlin) and colleagues have uncovered a genetic cause for the human familial advanced sleep phase syndrome (FASPS), which causes people to both go to sleep and wake up... view more...

Light-induced hormone surge points to benefits of light therapy
A report in the November Cell Metabolism reveals powerful effects of light on the adrenal glands, a finding that might explain the broad benefits of bright light therapy for a variety of conditions, including sleep and depressive disorders, according to researchers. view more (2005-11-09)
WUSTL research finds individual cells isolated from the biological clock can keep daily time, but are unreliable
Alexis Webb enters a small room at Washington University in St. Louis with walls, floor and ceiling painted dark green, shuts the door, turns off the lights and bends over a microscope in a black box draped with black cloth. Through the microscope, she can see a single nerve cell on a glass cover slip glowing dimly. view more (2009-09-10)
More evidence mammals, fruit flies share make-up on function of biological clocks
A study by researchers at New York University and the University of London offers additional evidence that mammals and fruit flies share a common genetic makeup that determines the function of their internal biological clocks. The study appears in the latest issue of Current Biology. view more (2006-03-07)
High rates of skin cancer among airline pilots
Rates and types of cancer were assessed in 458 pilots, 265 of whom flew the national Icelandic airline across European and transAtlantic routes. These were then compared with the rates of cancer expected to develop in the population as a whole, gathered from data supplied by the national cancer registry, according to age. view more (2000-02-14)
Seasonal Affective Disorder May Be Linked to Genetic Mutation, Study Suggests
With the days shortening toward winter, many people will begin to experience the winter blahs. For some, the effect can be devastating. view more (2008-11-04)
When neurons fire up: Study sheds light on rhythms of the brain
In our brains, groups of neurons fire up simultaneously for just milliseconds at a time, in random rhythms, similar to twinkling lightning bugs in our backyards. New research from neuroscientists at Indiana University and the University of Montreal provides a model -- a rhyme and reason -- for this random synchronization. view more (2008-08-06)
Kidney disease increases risk of sudden cardiac death for ICD patients
End-stage kidney disease significantly increases the risk of life-threatening heart rhythm abnormalities in patients with implantable cardioverter defibrillators (ICDs). view more (2006-09-19)
UNC study supports role of circadian clock in response to chemotherapy
For years, research has hinted that the time of day that cancer patients receive chemotherapy can impact their chances of survival. But the lack of a clear scientific explanation for this finding has kept clinicians from considering timing as a factor in treatment. view more (2009-01-13)
First molecular evidence of body's internal clock in controlling blood pressure
It has been known for decades that heart attacks and strokes occur most frequently in the early-morning hours. Now, researchers at the University of Pennsylvania School of Medicine have provided the first evidence for the role of our body's internal molecular clock in controlling blood pressure and a mechanism by which this occurs. view more (2007-02-20)
The first autism disease genes
The autistic disorder, a neurodevelopmental disease first described in 1943, represents a challenge for treatment and a puzzle for research. Alongside Asperger syndrome, a milder form of the disorder, autism is classified in the continuum of various Autism Spectrum Disorders (ASD), all of which are characterized by deficits in language, social... view more...

New Evidence on How our Eyes use Light to Manage our Body Clock - University of Surrey Groundbreaking Study Results
A new study published this week shows for the first time that the human eye is sensitive to short wave length visible light and transmits information to the body clock in a way that may make it possible to manipulate waking and sleeping rhythms. This new data, gained from a study carried out at the University of Surrey, might enable this type of... view more... (2001-08-20)
ESC Congress 2003: Spirolactone may normalize the circadian non-dipper blood pressure rhythm in salt-sensitive black hypertensives
IMPORTANT: This press release accompanies a poster or oral session given at the ESC Congress 2003. Written by the investigator himself/herself, this press release does not necessarily reflect the opinion of the European Society of Cardiology ESC Congress 2003: We have shown that spironolactone (a drug that is able to antagonise the effects of... view more...

Genetic pathway responsible for link between body clock disturbance and worsening arthritis
The genes that regulate human circadian rhythm, or 'the body clock', are significantly disturbed in individuals with arthritis. view more (2009-06-11)
Are you my mother? Transference more pronounced when we are tired.
Sigmund Freud hailed the phenomenon of transference as fundamental to the process of dynamic psychotherapy. Freud depicted transference as a false connection between patient's memories of a past relationship and the therapeutic context. He noted it as an integral part in the psychoanalytic cure. view more (2008-04-01)
The Jetlag of a Glowing Fish and More: Press Release from PLoS Biology
What Does an Airline Traveler Have in Common with a Glowing Fish? In William Gibson's novel Pattern Recognition, the protagonist posits a theory of jet lag: "Souls can't move that quickly, and are left behind, and must be awaited, upon arrival, like lost luggage." Science has yet to address the issue of a spiritual speed limit,... view more... (2005-01-25)
When a child's heart stops, onset time of abnormal rhythms is crucial
Ventricular fibrillation, the life-threatening disordered heart rhythms that may accompany full cardiac arrest, occurs more frequently in children than commonly believed, according to a large national pediatric study. view more (2006-06-01)
Light-sensing cells in retina develop before vision
Investigators at Washington University School of Medicine in St. Louis have found that cells making up a non-visual system in the eye are in place and functioning long before the rods and cones that process light into vision. view more (2005-12-22)
Multitasking is hardest in the early morning
Multitasking seems to come easier for some and is virtually impossible for others, however new research shows that it is difficult for all in the late night and early morning. view more (2007-05-07)
Networking around the clock
A Brandeis University study published in Cell this week shows for the first time experimentally that the circadian cells in fruit flies function as a network that enables the insects to adapt their behavior according to seasonal changes. view more (2007-04-09)
