The mammalian system for controlling bone remodelling also regulates fever The so-called RANK protein and the molecule that binds to it, the RANK ligand or RANKL, form a focus of the work of Josef Penninger, director of the Institute of Molecular Biotechnology (IMBA) in Vienna. In 1999 his group deleted the RANKL gene from mice and showed that the RANK/RANKL system was the "master regulator" governing bone loss (Kong et al. 1999 Nature 402, 304-309). The work provided the fist genetic proof...

The findings suggest new perspective on diabetes, metabolism and weight control A team led by scientists at The Scripps Research Institute have discovered a direct link between insulin"”a hormone long associated with metabolism and metabolic disorders such as diabetes"”and core body temperature. While much research has been conducted on insulin since its discovery in the 1920s, this is the first time the hormone has been connected to the fundamental process of temperature...

Scientists have discovered that one species of starfish has a remarkable strategy to avoid overheating in the sun, BBC News reported. Experts say the ochre starfish or sea star (Pisaster ochraceus) pumps itself up with cold seawater to lower its body temperature when exposed to the sun at low tide, something scientists say is equivalent to a person drinking seven liters of water before heading into the midday sun. But the researchers warn that global climate change may drastically interfere...

Marathon runners are famed for pasta packing in the days before a big run but when tiny passerine birds set out on their epic migrations, the distances are too great to cover on the energy reserves with which they embark. MichaÃ…“š Wojciechowski and Berry Pinshow explain that most birds stop off en route to their destination to refuel. One of the Eurasian blackcaps' preferred refueling stops is Midreshet Ben-Gurion, Israel, where the birds fill up on fruit and insects...

HARRISBURG, Pa., Aug. 10 /PRNewswire-USNewswire/ -- Health Secretary Everette James today reminded all Pennsylvanians to take necessary precautions to remain healthy and safe in extremely hot weather. "Many people do not understand just how dangerous hot weather can be. It's important to know what actions can be taken to prevent heat-related illness or death," said Secretary James. "The elderly, young children under the age of four, and people with mental illness and chronic diseases are...

Lizards are ectotherms -- animals whose body temperatures vary with surrounding temperatures. Ectotherms, which account for the largest population of animals on Earth, are found in the highest concentrations in tropical areas.Since the 1940s, scientists have known that lizards regulate their body temperatures by moving between sun and shade. Less well understood has been tropical lizards' adaptability to changes in the temperature and availability of shade in their environment.A study...

Have you ever covered yourself with a blanket to stave off the shivers? A new study shows that a blanket can also help alleviate shivering in patients who have been cooled to prevent brain damage.Patients with brain injuries or dangerously high fevers are often cooled to reduce their core body temperature to prevent further damage and aid healing. Unfortunately, cooling induces a natural and familiar response - shivering. This shivering counteracts efforts to keep the patient's temperature...

NEW YORK, July 2 /PRNewswire-USNewswire/ -- As we prepare for hotter, humid weeks ahead and temperatures reach well over 100 degrees in some parts of the country, older adults are at higher risk of health problems if they don't take the proper precautions to protect themselves from the sweltering heat. About 200 Americans die of health problems caused by high heat and humidity every year, most of them are 50 or older. Due to some of the physical changes that happen as we age, older adults...

A new study has found that as the climate continues to get warmer, the rate of molecular evolution in mammals could speed up as they attempt to regulate their body temperature. A study of the same species in different climates found that the DNA of those living in warmer conditions were changing at a faster rate, researchers told BBC News. According to the study published in the Proceedings of the Royal Society B, lead author Len Gillman from Auckland University of Technology and colleagues...

The common research worm, C. elegans, is able to use heat-sensing nerve cells to not only regulate its response to hotter environments, but also to control the pace of its aging as a result of that heat, according to new research at the University of California, San Francisco.The new findings have turned upside down a widespread assumption about how cold-blooded animals respond to and regulate heat, the researchers say. The study is reported in the online early edition of the journal "Current...
