Researchers have found new insights into how water from melting ice could have helped in the formation of ravine-like channels that cut down the sides of impact craters on Mars.Called Martian gullies, which look similar to gullies that form on Earth in the Dry Valleys of Antarctica, are caused by water erosion from melting glaciers. The researchers, published their paper in Science, found that when Mars tilts on its axis to 35 degrees, the atmosphere becomes dense enough for brief episodes of melting to occur at gully…

The East Anatolian fault zone was the site of two devastating earthquakes that occurred in Turkey and Syria in February 2023. While the University of Minnesota-led team's findings won't help predict timing or size of earthquakes, it allows geologists to learn more about how long the area has been seismically active and how major earthquakes have shaped the landscape over time.

A groundbreaking study from the University of Copenhagen has presented a fresh perspective on Earth’s formation, suggesting it occurred in a few million years, far quicker than the previously believed 100 million years. The research indicates that Earth was formed through the fast accumulation of small pebbles, and water’s existence is a byproduct of this formation process. This theory provides a promising outlook for the potential of habitable planets beyond our Solar System, given that water is a critical ingredient for…

Twitter Inc. has ceased to be an independent company after merging with a newly formed shell firm called X Corp., driving speculation about what Elon Musk intends for the social media platform.Twitter “no longer exists” after being merged with X Corp., according to an April 4 document submitted in a California court for a lawsuit filed against the company and its former chief executive officer, Jack Dorsey, last year by conservative activist Laura Loomer.It's unclear what the change means for Twitter, which has seen a…

Rochester researchers Wriju Chowdhury and Dustin Trail reveal information about early Earth using tiny zircon crystals, which are billions of years old and a fraction of a millimeter in size (scale bars are in micrometers, where 1 micrometer = 0.000001 meter). The researchers use an imaging technique called cathodoluminescence that fires electrons from a cathode at a sample. The holes in the crystals are from a laser that removed part of the grain to…

Given an array of positive integers arr. The task is to Find the minimum positive value which cannot be formed using OR operator on any subset of the array.Examples:Input: arr = {2, 3}Output: 1Explanation: Since 1 is missing from array and we cannot make it using OR for any other subset of this array, so it is the minimum positive value.Input: arr = {1, 2, 4}Output: 8Explanation: 1, 2 and 4 are already there in the array. Other numbers which can be formed are 3(1|2), 5(1|4), 6(2|4), 7(1|2|4) where “|” represents OR. So in…

Global crypto rules will be formed on a new synthesis paper to be based on the coming FSB The International Monetary Fund (IMF) and the Financial Stability Board (FSB) jointly produced a new synthesis paper that will serve as the foundation for future global crypto rules, announced India as the Group of 20 (G20) Presidency in Bangalore on Saturday. The announcement of global crypto rules will be formed came after three days of meetings in India among the world’s 20 largest economies, known collectively as the G20, with a…

Given N poles, each pole consists of hi number of vertices. Vertices on each pole are numbered from 1 to hi, the task is to find the longest simple chain formed by N poles, given the start and end point connections where the poles are connected in one graph in the following way:The first pole is ignoredAn edge connects the 1st vertex of the ith pole with the aith vertex of (i-1)-th pole.An edge connects the last vertex of the ith pole with the bith vertex of the (i-1)-th poleExamples:Input: N = 4H = {3, 4, 3, 3}  //Height…

The formation of the solar system remains one of the biggest mysteries in astronomy and planetary science. Scientists believe that the solar system formed around 4.6 billion years ago from a cloud of gas and dust known as the solar nebula. However, the exact process by which this happened and how the planets formed is still not fully understood.<span class="glossaryLink" aria-describedby="tt" data-cmtooltip="<div class=glossaryItemTitle>UCLA</div><div…
