Oil spills could be soaked up by a new floating substance that combines waste from the petroleum industry and cooking oil. The new polymer acted like a sponge to remove crude oil and diesel from seawater. The polymer can be squeezed to remove the oil and then reused.
Diamonds are flexible when made into nanoscale needles
Superionic ice has been created in the lab for the first time. The ultra-conductive version of ice, which accounts for 60% of Uranus and Neptune, was formed by compressing ice to 25,000 times the atmospheric pressure felt at sea level. The resulting ice was sixty times denser than regular water.
Cold Temp Exposure Causes Epigenetic Changes in Fat Cells
Researchers found that simply being told that a performer is a professional or a student changes the way the brain responds to music. They also found that overcoming this bias took a deliberate effort.
Americans waste 150,000 tons of food each day – equal to a pound per person. USDA research shows people with healthy diets rich in fruit and vegetables are the most wasteful.

Strong carbon fiber artificial muscles can lift 12,600 times their own weight - The new muscles are made from carbon fiber-reinforced siloxane rubber and have coiled geometry, supporting up to 60 MPa of mechanical stress, providing tensile strokes higher than 25% and specific work of up to 758 J/kg.
Drowning caused 80% of deaths from Hurricane Harvey. Study finds 78% of those deaths occurred outside zones designated as being at higher risk for flooding. US authorities outline floodplains for 100 and 500 year floods that had a 1% and 0.2% probability respectively of occurring in any given year.
Machine Learning algorithm can predict evolution of chaotic models without knowing the equations. This may improve weather prediction some day.
'Exploding Ant' Rips Itself Apart To Protect Its Own
Marijuana's effects on young brains diminish 72 hours after use, research says. Findings could be an indication that some of the negative cognitive effects found in previous studies may be due to the residual effects of cannabis or potentially from withdrawal effects in heavy cannabis users.
