the radiocarbon dating that is restricted to samples less than 50,000 years.
The half-life of Beryllium-10 is 1.4 million years.
So, it is enabling it to be applied to dating geological events over millions of years.
World's sea-ice falls
The frozen oceans present in the world that contribute towards cooling the planet are now having less ice than ever before.
This most recent sea-ice low seems to have been powered by a mixture of warm air, warm seas, and winds shredding the ice.
The total area of the Arctic and the Antarctic sea-ice was 15.76 million sq km (6.08 million sq miles).
This is the lowest 5 days since January-February 2023, when it was 15.93 million sq km (6.15 million sq miles).
Arctic sea-ice is now at its lowest area ever recorded at this time of year.
Antarctic sea-ice is near a historic low in satellite history dating back to the late 1970s.
Mass Nesting 2025
After two years, the biggest number of the endangered Olive Ridley Sea turtles, 6.5 lakh of them, has arrived at the Rushikulya beach in the Ganjam district of Odisha to go nesting in large numbers.
This is so far the most turtles that has ever arrived at the Rushikulya beach.
In 2023-24 and 2024-24, some rare nestings were observed along Rushikulya.
The final big congregation occurred in 2022-23.
The Indian Coast Guard has been extending a round-the-clock aid to the Central and State authorities since 1991, in the protection of endangered species under the Wildlife Act, 1972.
Iraq's Zagros Mountains
The area around the Zagros mountains in the north of Iraq is sinking.
The Researchers has discovered that a sinking oceanic slab beneath the surface of the earth is dragging the northern part of Iraq towards it.
There is a developing tear in an area between the Arabian and Eurasian continental plates called Neo Tethys oceanic slab.
The slab that made the floor of an ancient ocean over 66 million years ago is tearing apart between southeast Turkey and northwest Iran.
Now the slab is sinking into the mantle of the earth.
This is a complicated process requiring tens of millions
