Jackdaws recognise each other’s voices and respond in greater numbers to warnings from familiar birds than strangers, new research shows.

The renewable energy industry employs 10.3 million people worldwide, according to new data from the International Renewable Energy Agency (IRENA). And the sector is growing rapidly, adding more than 500,000 jobs last year alone, an increase of 5.3 percent from 2016, PV Magazine reported.

Placing giant mirrors in orbit to reflect sunlight before it reaches Earth and launching millions of tons of sulfur into the stratosphere to simulate the effects of a major volcanic eruption are among the mind-boggling climate geoengineering projects that are starting to be considered as ways to mitigate the global warming caused by greenhouse gases.

A complex genetic analysis has biologists re-evaluating some long-held beliefs about the way societies evolved following the invention of agriculture — by six-legged farmers.

Connected cruise control uses vehicle-to-vehicle communication to let automated vehicles respond to multiple cars at a time in an effort to save energy and improve safety.

Mixed forests are more productive than monocultures. This is true on all five continents, and particularly in regions with high precipitation. These findings from an international overview study, in which the Technical University of Munich (TUM) participated, are highly relevant for forest science and forest management on a global scale.

Dozens of potentially habitable planets have been discovered outside our solar system, and many more are awaiting detection.

Is anybody — or anything — there?

Hurricanes that intensify rapidly — a characteristic of almost all powerful hurricanes — do so more strongly and quickly now than they did 30 years ago, according to a study published recently in Geophysical Research Letters, a journal of the American Geophysical Union.

A new satellite that measures and provides detailed carbon balance information is one of the most important new tools in carbon measurement since infrared light, believe researchers from the University of Copenhagen. The researchers expect the satellite to be a valuable tool for the UN’s work on climate change related to the Paris climate accord.

NOAA’s National Weather Service is tapping technology to automate weather balloon launches in Alaska, a move that will allow staff to improve public service across the state while saving federal tax dollars.
