Gullies on the slopes of Martian craters were likely created by the “very recent” flow of water, according to a new study that sheds more light on whether life could exist on the Red Planet.
The presence of life on a planet, as it is seen on Earth, goes hand in hand with the existence of liquid water.
Researchers have previously shown that there may have been past periods on Mars when liquid water likely formed gullies if Mars tilted enough on its axis.
When black holes and other enormously massive, dense objects whirl around one another, they send out ripples in space and time called gravitational waves. These waves are one of the few ways we have to study the enigmatic cosmic giants that create them.
Astronomers have observed the high-frequency “chirps” of colliding black holes, but the ultra-low-frequency rumble of supermassive black holes orbiting one another has proven harder to detect. For decades, we have been observing pulsars, a type of star that pulses like a lighthouse, in search of the faint rippling of these waves.
Today, pulsar research collaborations around the world – including ours, the Parkes Pulsar Timing Array – announced their strongest evidence yet for the existence of these waves.
Scientists have witnessed something extraordinary. According to new reports and research, scientists watched healing metal, where cracked metal fused back together without any kind of human intervention. The discovery is one that could completely change how machines work, because machines are often victims of what we call fatigue damage.
Fatigue damage is essentially one of the main ways that machines wear out, causing them to break over time. This is a natural condition that happens as machines go through repeated stress and motion, which causes microscopic cracks to form in the metal. Over time those cracks grow more, eventually spreading until the entire device breaks or fails.
The scientists say that this latest discovery only showcases that metals have their own “intrinsic, natural ability to heal,” at least when it comes to fatigue damage at a nanoscale. For other, much larger cracks, the healing process may be unlikely or slow. It’s unclear.
Americans’ belief in God, the devil and other spiritual entities has fallen to a new low, according to a Gallup poll released on Thursday.
Seventy-four percent of Americans said they believe in God, while 69 percent said they believe in angels and 67 percent said they believe in heaven, the poll found. Slightly smaller shares — 59 percent and 58 percent — said they believe in hell and the devil.
Belief in all five spiritual entities has fallen between 3–5 points since 2016, the last time that Gallup polled Americans on the topic.

New work suggests four distinct star system types—and finds our own in the rarest category.
A researcher has used the technique of chemical mapping to study the spiral arms of our home galaxy: the Milky Way. According to Keith Hawkins, assistant professor at The University of Texas at Austin, chemical cartography might help us better grasp the structure and evolution of our galaxy.
“Much like the early explorers, who created better and better maps of our world, we are now creating better and better maps of the Milky Way,” mentioned Hawkins in an official release.

Built using inexpensive semiconductors, the device packs all components to make hydrogen and can be scaled.
A research team led by Aditya Mohite, a professor of chemical and biomolecular engineering at Rice University in the US, has designed a device that can use sunlight to generate hydrogen, with a record efficiency of 20.8 percent, a press release said.
Hydrogen is being touted as the future of clean energy due to its high energy density that could be deployed even to fly large planes. However, the process of generating hydrogen is currently heavily dependent on fossil fuels. For hydrogen to herald a new future in clean energy, it needs to be produced sustainably and without carbon emissions.
Will journalists and reporters soon run out of jobs?
Google is meeting with organizations under the Murdoch-owned News Corp umbrella — The New York Times, The Washington Post, and The Wall Street Journal — to pitch them its AI tool, which can produce and write news stories.
The tool’s name is reportedly Genesis, and it is being pitched by Google to enhance journalism productivity, according to an exclusive report by The New York Times.
The supercomputer is part of the larger constellation of inter-connected supercomputers with a combined capacity of 36 exaFLOPS.
Abu Dhabi-based technology holding group G42 has unveiled the world’s fastest supercomputer, the Condor Galaxy-1 (CG-1), which has 54 million cores and a processing capacity of four exaflops, a press release said. The supercomputer is located in Santa Clara, California, and will be operated by Cerebras, a US-based AI firm under US laws.
As artificial intelligence (AI) technology takes center stage, there is a strong demand for supercomputers to help businesses train their own models. Companies like Microsoft have offered to build the extremely expensive infrastructure and rent it out for companies to work on them.
