Gas stoves can emit climate pollution, even when they are off: Research

One form of pollution from gas stoves is methane, the main component of natural gas. Although methane does not pose a direct threat to human health, it is a greenhouse gas 80 times more potent than carbon dioxide during its first 20 years in the atmosphere.

When researchers measured emissions in 53 stoves across California, they found that all but one of them leaked methane when the burners and oven were turned off. (Representational Image)

How dengue-carrying mosquitoes evolve to become resistant to insecticides

Japanese scientist Shinji Kasai and his team examined mosquitos from several countries in Asia as well as Ghana and found a series of mutations had made some virtually impervious to popular pyrethroid-based chemicals like permethrin.

Health authorities commonly fog mosquito-infested areas with clouds of insecticide, and resistance has long been a concern, but the scale of the problem was not well understood.(AFP/ Representative image)

Researchers suggest how brain games predict risk of viral infection

Subtle variations in every day cognitive performance can signal changes in brain states that are known to increase the risk of illness such as stress, fatigue and poor sleep. The team wanted to measure cognitive function and explore whether it was predictive of immune performance after exposure to a respiratory virus.

Cognitive variability, measured with an at-home, digital self-test, turned out to be very predictive.(Reuters)

‘Ionocaloric cooling’: New method of refrigeration technique developed

Researchers hope that the method could one day provide efficient heating and cooling, which accounts for more than half of the energy used in homes, and help phase out current "vapor compression" systems, which use gases with high global warming potential as refrigerants.

Ionocaloric refrigeration would eliminate the risk of such gases escaping into the atmosphere by replacing them with solid and liquid components.(Unsplash)

Study finds important clues to dispersal of giant rhinos across Asia

According to a study published in the journal "Communications Biology," the giant rhino, Paraceratherium, was dispersed across South and Central Asia via the Tibetan Plateau.

Up to the Late Oligocene, the evolution and migration from P. bugtiense to P. linxiaense and P. lepidum show that the "Tibetan Plateau" was not yet a barrier to the movement of the largest land mammal.
