Active optical clock
Institute of Quantum Electronics, School of Electronics Engineering and Computer Science, Peking University, has proposed the concept, principles and techniques of active optical clock. view more (2009-04-13)
Genes linked to daily flux in drug toxicity
New findings in the July, 2006, Cell Metabolism, published by Cell Press, may help to explain daily fluctuations in the ability to detoxify chemical substances, including chemotherapy drugs and sedatives. view more (2006-07-06)
Ytterbium gains ground in quest for next-generation atomic clocks
An experimental atomic clock based on ytterbium atoms is about four times more accurate than it was several years ago, giving it a precision comparable to that of the NIST-F1 cesium fountain clock, the nation's civilian time standard, scientists at the National Institute of Standards and Technology (NIST) report in Physical Review Letters. view more (2009-08-12)
Prenatal alcohol exposure can alter circadian rhythms in offspring
Children with fetal alcohol spectrum disorders (FASD) suffer from a variety of behavioral alterations. For example, they may exhibit alterations in sleeping and eating patterns, which may indicate that their circadian systems - which control biological rhythms - have been affected by alcohol exposure during development. view more (2006-04-24)
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)
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)
Study shows more genes are controlled by biological clocks
The tick-tock of your biological clock may have just gotten a little louder. Researchers at the University of Georgia report that the number of genes under control of in living things than suspected only a few years ago. view more (2008-08-29)
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)
Researchers publish first working model that explains how biological clocks work
Science has known for decades that biological clocks govern the behavior of everything from humans to lowly bread mold. These ticking timekeepers hold the key to many diseases, annoy passengers on intercontinental flights and can mean life or death for small creatures trying to survive in nature. view more (2007-02-13)
Different Processes Govern Sight, Light Detection
A Johns Hopkins University biologist, in research with implications for people suffering from seasonal affective disorder and insomnia, has determined that the eye uses light to reset the biological clock through a mechanism separate from the ability to see. view more (2008-04-28)
OHSU primate center research suggests multiple 'body clocks'
Research conducted at Oregon Health & Science University suggests that contrary to popular belief, the body has more than one "body clock." view more (2006-05-23)
FLYING THROUGH TIME
UK scientists demonstrate Einstein's theories of relativity and 'travel' through time view more (1999-12-22)
Racing against the clock to distribute H1N1 flu vaccine
Drug companies are sprinting ahead in a race against the clock to deliver millions of doses of vaccine for the H1N1 influenza virus before cooler weather ushers in the 2009-2010 flu season. view more (2009-10-01)
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)
Atomic clock signals may be best shared by fiber-optics
Time and frequency information can be transferred between laboratories or to other users in several ways, often using the Global Positioning System (GPS). But today's best atomic clocks are so accurate—neither gaining nor losing one second in as long as 400 million years—that more stable methods are needed. view more (2007-03-05)
Artificial light at night stimulates breast cancer growth in laboratory mice
Results from a new study in laboratory mice show that nighttime exposure to artificial light stimulated the growth of human breast tumors by suppressing the levels of a key hormone called melatonin. view more (2005-12-20)
Bright lights, not-so-big pupils
A team of Johns Hopkins neuroscientists has worked out how some newly discovered light sensors in the eye detect light and communicate with the brain. The report appears online this week in Nature. view more (2009-01-05)
Melatonin improves mood in winter depression
Researchers at Oregon Health & Science University(OHSU) have found that melatonin, a naturally occurring brain substance, can relieve the doldrums of winter depression, also known as seasonal affective disorder, or SAD. view more (2006-05-02)
NIST atomic fountain clock gets much better with time
The world's best clock, NIST-F1, has been improved over the past few years and now measures time and frequency more than twice as accurately as it did in 1999 when first used as a national standard, physicists at the National Institute of Standards and Technology (NIST) report. view more (2005-09-26)
'Suction climbing' and Vertical Cycling at TU Delft
Invitation to the final of the design contest at Mechanical Engineering 'Suction climbing' and Vertical Cycling at TU Delft Students that climb along walls and ceilings like geckos, or that ride a bike up a cable. This can be seen at TU Delft on 7 June 2002, during the annual design contest at the Faculty of Mechanical Engineering. "At this... view more... (2002-06-04)
