Climate model links higher temperatures to prehistoric extinction
Virginia Commonwealth University immunologists studying mast cells, known to play a central role in asthma and allergic disease, have identified a hormone-like molecule that can kill these cells by programming them to die in studies with mice. The findings move researchers another step closer to understanding the life cycle of mast cells, and may help researchers develop new treatments fo...Temperature regulates circadian clock in zebrafish
The biological clock controls the circadian rhythms of a wide range of physiological and behavioral processes, from fluctuating hormone levels to sleep-wake cycles and feeding patterns. While it's well known that circadian clock elements sense and respond to light cycles, much less is known about how daily temperature cycles affect the clock's timing mechanism in vertebrates. In the open-access...Elevated temperature enhances success of viral cancer therapy
A therapeutic approach for battling cancer that is based on infection with a specially designed virus similar to the one that causes the common cold has shown promise in clinical trials. Now, new research suggests that fever might be a useful weapon in the fight as well. The study, published in the July issue of Cancer Cell, demonstrates that tumor cells are even more sensitive to viral therapy a...Taking evolution's temperature: Researchers pinpoint the energy it takes to make a species
Comfortable living is not why so many different life forms seem to converge at the warmer areas of the planet. The finding - by researcher...Time of day tempers tadpoles' response to predators
To a tiny tadpole, life boils down to two basic missions: eat, and avoid being eaten. But there's a trade-off. The more a tadpole eats, the faster it grows big enough to transform into a frog; yet finding food requires being active, which ups the odds of becoming someone else's dinner. Scientists have known that prey adjust their activity levels in response to predation risk, but new res...pMIR-mU6, Mouse U6Template (Vector) from Mirus Bio Corporation
Description:The potential applications for the use of small interfering RNA (siRNA) molecules to silence gene expression via the RNA interference(RNAi) pathway have generated tremendous interest in the cellular and molecular biology fields. siRNA for experimental use can besynthesized in vitro, either chemically or enzymatically, and then transfected into the target cells in vitro or in vivo [1-4].

Problems with the amplification of a specific DNA fragment using the PCR* are an everyday occurrence in the lab. For example, unspecific secondary bands may form after the PCR reaction, which hinder, or even prevent, further analyses (cycle sequencing, mutation detection, etc.) or an unequivocal assessment of the PCR r...TripleMaster and Perfect gDNA Blood Mini Kit Team Up to Amplify Long gDNA Templates

Eppendorf 5 Prime, Boulder, CO, USA The polymerase chain reaction (PCR*) is a powerful and sensitive technique used by scientists to amplify large quantities of DNA. Although the reaction mix and thermal cycling conditi...Acne Drug linked to suicide attempts
One year ago the FDA issued a statement about the potential for depression and suicide in teens taking the acne drug, Accutane. And now, reports say that the 15-year-old pilot who crashed his plane into a skyscraper was prescribed the drug. At this point, investigators don't know whether or not the teen, Charles J. Bishop, was actually taking Accutane at the time of his death. Blood tests...Attempting Hypnosis for relaxation
According to researchers at the Mayo Clinic, promote a simple form of self-hypnosis to induce relaxation and deal with stress. Hypnotherapy can be a great way to break bad habits like smoking,// reduce stress and relieve pain. Its success depends upon why it is being used, and how readily the person can enter the altered awareness of the hypnotic state, say doctors at the Mayo Clinic. But...Brain Temperature Tunnel dicovered
Physician and scientist M. Marc Abreu, M.D., says he has uncovered an area of the brain called the brain temperature tunnel. In what he calls a remarkable discovery, he says this precise area of the brain controls the key function and critical factor for life preservation and human performance -- brain temperature. Through his research, he has discovered that a small area of skin near the...Contemplating the effects of the “Morning After“ Pill
A recent study has shown that the ''morning after'' contraceptive pills work// by interfering with ovulation thereby preventing fertilization and not by preventing implantation of a fertilized egg. Reproductive physiologists demonstrated the phenomenon in a controlled clinical trial published in the December 2004 . When the pills, also known as emergency contraception (EC) were given be...Anxiety Can Increase The Risk Of Attempting Suicide In Men
Swedish researchers had reported that men who report feeling nervous and anxious are nine times likely to attempt suicide than their counterparts who perceive themselves as relaxed. Their research findings were published // in the current issue of Journal of Epidemiology and Community Health. The findings are based on results from the Swedish Survey of Living Conditions, a representati...Temporal Approach Lid Speculum
