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...ThermoClamp-1 Temperature Control System (8 Ch.) from AutoMate Scientific, Inc

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...Rapid PCR* Using Active Tube Temperature Control On Thermo's PCR Machines
Solutions Note The time taken to complete a standard PCRprotocol is becoming increasingly important forresearchers today. Whilst many manufacturers ofthermal cyclers focus on pushing the limits of ramprates, in this article we highlight how Thermo's approach of focussing on ach...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...Evolution influenced by Temperature change
Professor Hunt and Roy from University of California, San Diego has published in the Journal Proceedings of the National Academy of Sciences// their views on evolution of bigger animals from small animals. Researchers found that evolution also occurred in deep sea animals and they found that over time transmission of animals from occurred mostly by increase in size and they found tha...98.6 degrees no longer the benchmark for normal temperature
Dr. Carl Wunderlich, a 19th-century German physician gave us the magic figure of 98.6 degrees. This was done by him after collecting and analysing over a million armpit temperatures for 25,000 patients.// This has been corrected by Harvard researchers and appears in the April issue of the Harvard Health Letter. The average normal temperature for adults is found to be 98.2 degr...Sensor Images Show Soaring Temperature and Pollution Levels in UK
Summer temperatures have been on an all time high in the United Kingdom, and space sensors have also been keeping tabs on the rising temperature and pollution levels. //According to the Met office reports, during the period from 15th to 19th July, the temperatures were a record high in UK along with nitrogen dioxide pollution, which is known to trigger a host of respiratory problems....Cooling Temperatures Help Crucian Carp
Crucian carp, which is a sort of cousin to a goldfish, is able to store vast amounts of glycogen in its brain, due to the cooling temperatures present in water. //This will allow it to keep its brain healthy despite there being no oxygen in ponds between February and April The study from Finland found that the amount of glycogen in the brain was at its peak in February, when the pond...I-Stat Low Temperature Cautery, Fixed
