Could help scientists track paleoclimate, determine whether dinosaurs and other species were warm- or cold-bloodedWas Tyrannosaurus rex cold-blooded? Did birds regulate their body temperatures before or after they began to grow feathers? Why would evolution favor warm-bloodedness when it has such a high energy cost?Questions like these"”about when, why, and how vertebrates stopped relying on external factors to regulate their body temperatures and began heating themselves internally"”have...
ATLANTA, May 11 /PRNewswire/ -- Hothead Technologies has executed an agreement with Shafer Medical Devices, a Division of Shafer Enterprises, LLC to develop and distribute a medical application of the H.O.T.(TM) System that supports the Shafer Medical Devices Hypo/Hyperthermic Pad in managing normothermia in patients, during pre-op, surgery, and post op. The H.O.T.(TM) System, created by Hothead Technologies, wirelessly monitors body temperature, sending warning signals if the individual's...
SALZBURG, Germany, April 13 /PRNewswire/ -- Many people suffer from underarm wetness. Special pads from COSMEA now offer an effective protection. These adhesive pads ensure hygienically dry skin, protect clothing from those unwanted sweat stains, and work against perspiration odor without losing that safe feeling.

That bracing morning shower and soothing bedtime soak in the tub are potentially important but until now unrecognized sources of the hormones, antibiotics, and other pharmaceuticals that pollute the environment, scientists reported yesterday at the 239th National Meeting of the American Chemical Society. The first-ever evaluation, they said, could lead to new ways to control environmental pollution from active pharmaceutical ingredients (APIs), which has been the source of growing...
People in seven European countries have positive attitudes toward a new eco-friendly toilet that could substantially reduce pollution problems and conserve water and nutrients, scientists in Switzerland are reporting. Their article, which calls on authorities to give wider support for the innovative toilet technology, is in ACS' Environmental Science & Technology, a semi-monthly journal.Judit Lienert and Tove Larsen note in the article that the so-called NoMix toilet collects urine...
New study shows wild female bats' temperature regulation strategy is flexibleIn order to regulate their body temperature as efficiently as possible, wild female bats switch between two strategies depending on both the ambient temperature and their reproductive status. During pregnancy and lactation, they profit energetically from clustering when temperatures drop. Once they have finished lactating, they use torpor* to a greater extent, to slow their metabolic rate and drop their body...
In a surprising finding, researchers at North Carolina State University have discovered the critical importance of a protein previously believed to be a redundant "on switch" for certain immune-system responses.Scientists previously understood that the protein called TAB2Â activates inflammation, an important biological process that stimulates wound-healing and prevents invasion of harmful organisms. But scientists considered TAB2 nonessential to the process due to the redundant function...
QUAKERTOWN, Pa., Jan. 15 /PRNewswire-USNewswire/ -- Does excessive sweating at the airport make you a potential terrorist? Last week's news that more airports are considering training officials to examine a passenger's body language and behavior in an attempt to help identify potential threats is welcome news that will help strengthen travel safety measures. However, including 'excessive sweating' as a warning sign of potential criminal activity may add to the confusion instead of...
We all have at one time or another experienced the typical signs of an infection: the fever, the listlessness, the lack of appetite. They are orchestrated by the brain in response to circulating cytokines, the signaling molecules of the immune system. But just how cytokines' reach extends beyond the almost impenetrable blood-brain barrier has been the topic of much dispute.In their latest study, researchers at the Salk Institute for Biological Studies describe how, depending on the nature of...
The International Space Station's $250 million water recycling system is facing a problem as the astronauts' urine is clogging the system that turns it into drinkable clean water, according to NASA scientists.The engineers trouble-shooting the problem think the clog is a result of high concentrations of calcium in the astronaut's urine, reported Reuters.Scientists are now trying to determine if the high concentration of calcium is because of bone-loss from living without gravity, or some...
