EU Struggles to Agree 2030 Climate Targets for October Summit

European Union leaders face difficult negotiations to agree a package of climate change targets for 2030 at an end-of-October summit, with coal-reliant Poland leading objections, sources said Friday.

Plans to cut greenhouse gases by 40 percent, make renewables account for 27 percent of energy use and set an energy savings target of 30 percent appear in draft guidelines for the summit conclusions, seen by Agence France Presse.

Methane Hot Spot in U.S. is 3x Expected Size

One area in the southwestern United States is spewing vast amounts of methane, a potent greenhouse gas, into the atmosphere far faster than expected, U.S. space agency researchers said Thursday.

Satellite data show more than triple the previously estimated amount of methane is coming from the hot spot located near the Four Corners intersection of Arizona, Colorado, New Mexico and Utah.

Days of Heavy Air Pollution Blight Northern China

Days of heavy smog shrouding swathes of northern China pushed pollution to more than 20 times safe levels on Friday, despite government promises to tackle environmental blight.

Visibility dropped dramatically as measures of small pollutant particles known as PM2.5, which can embed themselves deep in the lungs, reached more than 500 micrograms per cubic meter in parts of Hebei, a province bordering Beijing.

Step Toward Artificial Hand with a Sense of Touch

Scientists are moving closer to an artificial hand that can feel: Implanted electrodes allowed some amputees to tell by touch how gently to grasp, letting them pluck fruit without crushing it.

The two men told researchers at Case Western Reserve University that wiring some of their remaining nerves to a robotic arm — albeit only during visits to a lab — felt more like grasping objects with their own hand than with a tool.
