60-Second Astro News: Light Pollution, Birds, and Zambuto Mirrors

    From: - Sky & Telescope  By :- Camille M. Carlisel   Edited by :- Amal Udawatta Constant Contact Use. Please leave this field blank. A male northern cardinal makes its voice heard. Cardinals are one of hundreds of species included in a recent study of light pollution's effects on when diurnal birds begin and end their days. Shiva Shenoy / Wikimedia Commons / CC-BY-2.0 In this roundup of recent news, birds react to light pollution and a respected mirror maker calls it a day. Light Pollution Is for the Birds A study of the songs from hundreds of diurnal bird species indicates that, on average, birds in light-polluted areas wake up earlier and stay up later.  Scientists had already documented such activity for specific species , but Brent Pease (Southern Illinois University, Carbondale) and Neil Gilbert (Oklahoma State University) say their study is unique because it combines data across species, spaces, and seasons. The researchers used millions of observa...

Is Earth the only planet in the solar system with plate tectonics?

       From  - Live Science    By - Skyler Ware   Edited by - Amal Udawatta Earth is the only body in the solar system that currently exhibits plate tectonics, whose movements explain this surface crack along the San Andreas Fault.   (Image credit: Bob Rowan via Getty Images) Plate tectonics give Earth its mountains, earthquakes, continental drift and maybe even helped give rise to life itself. But do other planets in the solar system have them too? Plate tectonics give rise to Earth's mountain ranges, earthquakes and the long-term movement of continents, and may even have  provided the right conditions for life on Earth . But as far as we know, no other bodies in the  solar system  exhibit plate tectonics today. Why is our world different? "We don't know for sure,"  Bradford Foley , a geodynamicist at Penn State, told Live Science. "I think it's still considered one of the great unsolved problems in geophysics today." Ear...

From a Trump presidency to 'game-changing' lawsuits: Seven big climate and nature moments coming in 2025

      From -BBC World News   By-  Jocelyn Timperley and Isabelle Gerretsen   Edited by - Amal Udawatta Getty Images Some key events coming up in 2025 have game-changing potential for our planet. Here, two of the BBC's environment journalists analyse what they could mean for the climate and nature. As countries unveil new climate targets, Donald Trump enters the White House for a second term and a potentially game-changing ruling for future climate lawsuits unfolds – 2025 is set to be a big year for climate and nature.  Speaking in his  New Year's message  in late December, secretary-general of the United Nations  António Guterres said that the world is witnessing "climate breakdown – in real time".  "We must exit this road to ruin. In 2025, countries must put the world on a safer path by dramatically slashing emissions and supporting the transition to a renewable future," he said, stressing that "it is essential – and it is possible...
