[ad_1] For decades, scientists believed the world’s tallest trees faced a fundamental disadvantage during drought. The higher a tree grows, the harder gravity makes it for water to travel from the roots to the leaves, leading researchers to assume that towering rainforest giants would be especially vulnerable as the climate becomes hotter and drier. A…

[ad_1] Some of the world’s most advanced robots are preparing for an extraordinary expedition to one of the planet’s most dangerous environments. Beginning this July, a fleet of autonomous drones, robotic boats, underwater vehicles and intelligent sensors will travel to Greenland to investigate how its glaciers are melting where they meet the ocean. The mission,…

[ad_1] For decades, astronomers have searched for the birthplace of globular clusters, the dense spherical collections of stars that orbit galaxies today. These ancient systems are among the oldest visible structures in the Universe, yet their earliest history remains surprisingly difficult to reconstruct. Most theories have focused on crowded regions inside young galaxies, where gas…

[ad_1] Australia’s renewable energy boom has reached a remarkable milestone. The country now generates so much electricity from rooftop solar panels that, during the middle of the day, wholesale power prices frequently fall to zero or even below zero. Instead of allowing surplus electricity to go to waste, eligible households in parts of Australia can…

[ad_1] Electricity generation from hydroelectric projects declined nearly 21%. (AI image) El Nino and the resultant weak monsoon has had an impact on India’s hydropower output, which has dropped by more than 20% in June. The dry weather, which is associated with El Nino, has meant that the water levels in reservoirs have gone down….

[ad_1] Football has a habit of borrowing the language of space. Players become stars, matches are described as astronomical, and careers are measured by how brightly they shine. Every so often, though, the comparison drifts into something more literal. More than a decade ago, astronomers studying one of the earliest known galaxies in the universe…

[ad_1] Archaeologists have deciphered a 1,700-year-old inscription at an ancient Roman temple in Turkey that offers rare written evidence of the shift from Mithraism to Christianity during the Roman period.The inscription was found at an underground Temple of Mithras inside Zerzevan Castle, a Roman fortification about 40 miles from the Syrian border. It was written…

[ad_1] Picture credit: True Anomaly For decades, space battles have belonged to the world of Star Wars and science fiction. But as more satellites fill Earth’s orbit, military powers are now preparing for a future where satellites may have to track, approach and respond to rival spacecraft in orbit.That idea moved a step closer to…
