Extreme weather decides distribution of insects
As climate change is progressing, the temperature of our planet increases. This is particularly important for the large group of animals that are cold-blooded (ectothermic), including insects. Their body ...
Magnesium oxide: From Earth to super-Earth
The mantles of Earth and other rocky planets are rich in magnesium and oxygen. Due to its simplicity, the mineral magnesium oxide is a good model for studying the nature of planetary interiors. New work from ...
The heat is on for sodium-manganese oxide rechargeable batteries
(PhysOrg.com) -- By adding the right amount of heat, researchers have developed a method that improves the electrical capacity and recharging lifetime of sodium ion rechargeable batteries, which could be a ...
Tiny generators turn waste heat into power
The second law of thermodynamics is a big hit with the beret-wearing college crowd because of its implicit existential crunch. The tendency of a closed systems to become increasingly disordered if no energy is added or removed ...
'Smart' high-tech dog collar goes on sale in Japan
A high-tech collar attachment that will allow pet owners to monitor their dogs at a distance, checking how much they sleep and how many calories they are burning, was unveiled Thursday in Japan.
A hot new look at working fuel cells
Measuring a fuel cell's overall performance is relatively easy, but measuring its components individually as they work together is a challenge. That's because one of the best experimental techniques for investigating ...
Gravitational tide the secret of Saturn's weird moon
Enceladus, a white moon of Saturn with ice-spewing volcanoes, owes its strangeness to tides of gravitational forces exerted by its mother, a study in Nature said on Wednesday.
Researchers create artificial mother of pearl, pave way for tough coatings
(Phys.org) -- Mimicking the way mother of pearl is created in nature, scientists have for the first time synthesised the strong, iridescent coating found on the inside of some molluscs. The research was published ...
Researchers find elephants cannot handle exercise on hot days
Shifts in physiological mechanisms let male bats balance the need to feed and the urge to breed
A forthcoming article in Physiological and Biochemical Zoology reveals shifts in the mechanisms bats use to regulate metabolism throughout their seasonal activity period.
Crystal clear research
(PhysOrg.com) -- Scientists have successfully created synthetic crystals whose structures and properties mimic those of naturally occurring biominerals such as seashells.
Cocaine-related deaths rise in warm weather
Researchers in the United States have discovered that accidental overdose deaths involving cocaine rise when the average weekly ambient temperature passes 24 degrees Celsius (75 degrees Fahrenheit).
Artificially controlling water condensation leads to 'room-temperature ice'
Earth's climate is strongly influenced by the presence of particles of different shapes and origins -- in the form of dust, ice and pollutants -- that find their way into the lowest portion of the atmosphere, the troposphere. ...
New insights into boron's chemistry at room temperature
(Phys.org) —Livermore researchers have described in detail the properties of the room temperature form of the element boron.
