Swatting at mosquitoes can teach them to stay away

Mosquitoes Target Delicious-Smelling Individuals – But Swatting Teaches Them To Stay Away (For Days)

A study at Virginia Tech has found that mosquitoes can rapidly learn and remember the smells of hosts. Delicious-smelling individuals are usually the preferred targets, but swatting at them or performing other defensive behaviours – can teach them to stay away, researchers say. "Unfortunately, there is no way of knowing exactly what attracts a mosquito … Continue reading Mosquitoes Target Delicious-Smelling Individuals – But Swatting Teaches Them To Stay Away (For Days)

Pollution Kills More People Annually Than All Wars And Violence Combined

Pollution Kills More People Annually Than All War And Violence Combined, Study Finds

Environmental pollution - from filthy air to contaminated water - is causing more deaths annually than all war and violence combined. According to a study published in the journal the Lancet, pollution around the world now contributes to at least one out of every six premature deaths (roughly 9 million), which is more than smoking, hunger or natural disasters, and more than AIDS, tuberculosis and malaria combined.

Earth's Mantle Holds As Much Water As Oceans

Study Claims Earth’s Mantle Holds As Much Water As Oceans

Researchers affiliated with several institutions in Japan and Germany have found evidence that suggests the middle of Earth's mantle holds as much water as the planet's oceans. In the study published in the journal Science Advances, researchers write that the uppermost part of the mantle and lower part closest to the core are relatively “water free” because their dominant minerals, “olivine and bridgmanite,” have limited water storage capacity. However, the layer in between (the mantle transition zone [MTZ] at 410 to 660 kilometers below the surface) could harbor massive amounts of water because it is dominated by the minerals "wadsleyite and ringwoodite," which are known to be able to hold a lot of water.
