Pong-in-a-Dish
Ever hear of the Turk—the 19th-century mechanism topped by a turbaned head that played chess against all comers? In fact, hidden inside was a diminutive chessmaster, one you might imagine deadpanning, “Eh, It’s a living.”Then there’s its n.....»»
Hunt for deep sea minerals draws scrutiny amid green push
High demand for metals ranging from copper to cobalt is pushing the mining industry to explore the world's deepest oceans, a troubling development for scientists who warn that extracting minerals from critical ecosystems that help regulate climate co.....»»
Study probes physiological mechanism of treeline formation from carbon allocation
Subalpine larch (Larix chinensis) is an endemic coniferous tree distributed above 3,100 m above sea level and forms treeline ecotone at the elevation of 3,450 m above sea level in the Qinling Mountains of north-central China. However, two prevailing.....»»
Capturing and analyzing subtle combination tones produced by violins
When two musical notes are played simultaneously, the human ear can perceive weak additional tones called combination tones. These subjective tones result from the nonlinearity of the inner ear and are attributed to the amplification mechanism of the.....»»
Clean hydrogen fuel is easier to produce from seawater with stable hierarchical electrocatalysts
Seawater, which comprises more than 95% of the Earth's water, could become a key resource in the sustainable production of clean hydrogen fuel with use of water-splitting catalysts developed by a KAUST-led team......»»
New cellular protective mechanism discovered
A vast number of biological reactions occur inside cells, generating various byproducts. Some of these can be highly reactive molecules, and if they build up inside cells they can cause stress and damage. One class of these molecules, reactive sulfur.....»»
