A systematic review found that ear thermometry is not a reliable method for measuring infants' body temperature, with wide individual differences and potential overestimation or underestimation of temperatures. This raises concerns about the accuracy of fever detection and precise temperature measurement in clinical settings.
Scientists found that warmer surface temperatures can splinter an ice shelf and prime it for a major collapse. The process is triggered by the added pressure from surface water filling crevasses, which can crack the ice entirely through.
A study by Stanford researchers reveals that global warming is causing a significant shift in marine species distribution, with many vulnerable intertidal creatures already struggling to cope. Rising temperatures are pushing species over their thermal tolerance range, leading to declines and potential extinctions.
A study suggests that disposable nappies lined with plastic can increase scrotal temperature in boys, potentially leading to impaired normal testicular cooling mechanisms and increased risk of male infertility. The research found that rectal temperatures were significantly lower than scrotal temperatures when cotton nappies were worn.
Scientists have discovered a cellular mechanism in hibernating ground squirrels that allows them to survive extreme cold and hypothermia. The study found changes in the cell membrane, specifically slits on neurons and glia, which enable proteins to function within selected lipid domains.
Researchers have discovered a metal wire with 'memory' that can help compress broken bones, leading to quicker healing times and better fusion of the bone. The alloy, Nitinol, resists loosening even after being absorbed by the bone, applying consistent pressure to promote proper healing.
A University of Illinois professor warns that decreasing sulfur dioxide emissions could exacerbate global warming by enhancing temperature changes in North America, Europe, and Asia. The studies used climate/ocean models to calculate the potential effects of reduced sulfur dioxide emissions on global-mean surface temperatures.
The US Navy has developed a new hot water suit with a layer of foam containing bits of wax inside tiny plastic beads to prevent heat loss in cold ocean depths. The wax absorbs warmth from the diver's body and melts, then freezes in icy waters, radiating latent heat back to the diver.
Researchers have identified a receptor protein in rodents and humans that can detect temperatures above 120 degrees Fahrenheit, expanding the range of temperatures for which nerve receptors are known. The discovery holds promise for better understanding pain and developing drugs to block pain.
A new ultrasonic scanner developed by Penn State researchers can image the interior of a material as it responds to temperature changes. The device was used to study a laminate material called PEEK, which is widely used in various consumer products, and demonstrated its ability to detect defects and monitor internal structure changes.
Researchers reconstruct past temperature changes using high-precision equipment, revealing a 4.5F warmer climate 5000 years ago and a 2F colder Little Ice Age. The region surrounding the North Atlantic Ocean is particularly sensitive to climatic changes due to ocean circulation patterns.
Io's volcanic hot spots reach surface temperatures of over 2,200 degrees Fahrenheit, more than double previous measurements. The extreme temperatures suggest a unique process of differentiation and heavy element composition, shedding light on the moon's geological history.
Maintaining a surgical patient's normal body temperature has been shown to reduce infections, speed healing and shorten hospital stays. Results of a clinical trial suggest a 55% risk reduction in cardiac complications when near-normal body temperatures are maintained.
