Understanding how oncogenes affect the body clock may help create better cancer treatments The Myc oncogene can disrupt the 24-hour internal rhythm in cancer cells. Postdoctoral fellow Brian Altman, PhD, and graduate student Annie Hsieh, MD, both from the in the lab of Chi Van Dang, MD, PhD, director of the Abramson Cancer Center, Abramson Family Cancer Research Institute, Perelman School of Medicine, University of Pennsylvania, present their data in the "Metabolic Pathway Regulation in...

Brett Smith for redOrbit.com - Your Universe Online Lack of sleep has long been known to have a negative impact on a person’s physiology, but a new study from researchers at the University of Surrey in the UK has found wide-ranging genetic implications that are associated with sleep deprivation. According to the team’s report, which appeared in the journal Proceedings of the National Academy of Sciences (PNAS), the function of over 700 genes were affected by sub-standard levels of...

Windows 8 opens up more opportunities for developers to offer educational apps that serve a wide variety of purposes. Jujuba Software recently released a Modern UI app for Windows 8 that provides convenient access to scientific information. (PRWEB) February 23, 2013 A Periodic Table of Elements can sometimes be tricky to follow and time consuming to locate the needed scientific information. Jujuba Software has unveiled the Windows 8 Periodic Table of Chemical Elements Modern UI app for...

When Thomas Edison tested the first light bulb in 1879, he could never have imagined that his invention could one day contribute to a global obesity epidemic. Electric light allows us to work, rest and play at all hours of the day, and a paper published this week in Bioessays suggests that this might have serious consequences for our health and for our waistlines. Daily or "circadian" rhythms including the sleep wake cycle, and rhythms in hormone release are controlled by a molecular clock...

Disruptions to the circadian rhythm can affect the growth of blood vessels in the body, thus causing illnesses such as diabetes, obesity, and cancer, according to a new study from Linköping University and Karolinska Institutet. The circadian rhythm is regulated by a “clock” that reacts to both incoming light and genetic factors. In an article now being published in the scientific journal Cell Reports, it is demonstrated for the first time that disruption of the circadian rhythm...

HONG KONG, July 29, 2012 /PRNewswire-Asia/ -- Financial Highlights for 2012 interim results: Revenue rose 13% year-on-year to approximately RMB2,031 million. Net profit attributable to owners of the parent increased 2.5-fold year-on-year to approximately RMB175 million. Overall gross profit margin advanced six percentage points to 18% from a year ago. Net cash inflows from operating activities more than tripled to RMB337 million when compared with the same period last year....

Women trying to have babies also need to think about circadian clock A new Northwestern University study shows that the biological clock is not the only clock women trying to conceive should consider. The circadian clock needs attention, too. Epidemiological studies have shown female shift workers, such as nurses, and female flight attendants who work on long-distance east-west routes (i.e., those with constant jet lag) have fertility and menstrual issues. They are habitually out of...

It's no secret that long-distance, west-to-east air travel – Seattle to Paris, for example – can raise havoc with a person's sleep and waking patterns, and that the effects are substantially less pronounced when traveling in the opposite direction. Now researchers, including a University of Washington biologist, have found hints that differing molecular processes in an area of the brain known as the suprachiasmatic nucleus might play a significant role in those jet lag differences....

LA JOLLA, Calif., Sept. 30, 2011 /PRNewswire-USNewswire/ -- Ever wondered why you wake up in the morning ---- even when the alarm clock isn't making jarring noises? Wonder no more. Researchers at the Salk Institute for Biological Studies have identified a new component of the biological clock, a gene responsible for starting the clock from its restful state every morning. The biological clock ramps up our metabolism early each day, initiating important physiological functions that tell our...

Do animals that have evolved for millions of years underground, completely isolated from the day-night cycle, still "know" what time it is? Does a normal circadian clock persist during evolution under constant darkness? A new study directly tackles these fundamental questions by investigating a species of cavefish, Phreatichthys andruzzii, which has lived isolated for 2 million years beneath the Somalian desert. Many fish species have evolved in the absence of sunlight in cave systems around...
