Data from NASA's Magellan spacecraft and Pioneer Venus Orbiter is used in an undated composite image of the planet Venus. Its thick and noxious atmosphere is dominated by carbon dioxide - 96.5% - with lesser amounts of nitrogen and trace gases. In fact, with Venus getting far less scientific attention than other planets such as Mars, the direct detection of its oxygen has remained difficult. They noted that this atomic oxygen, which consists of a single oxygen atom, differs from molecular oxygen, which consists of two oxygen atoms and is breathable. "The Venus atmosphere is very dense.

V. Knowing and UnknowingIt’s tempting to decide that all this seeing amounts to knowing. But some of Webb’s observations challenge fundamental assumptions in our timeline of the universe. ‘‘In general, star formation is very inefficient,’’ says Erica Nelson, assistant professor of astrophysics at the University of Colorado Boulder. In the latest models of cosmology, these unobserved phenomena make up 95 percent of the universe. Webb helps us know but also to “unknow”: It gives us stunning new discoveries while simultaneously challenging us to rethink and rebuild our understanding of the past.

New York CNN —Sam Altman thinks the technology underpinning his company’s most famous product could bring about the end of human civilization. As many as 300 million full-time jobs around the world could eventually be automated in some way by generative AI, according to Goldman Sachs estimates. Challenges aheadWhen starting OpenAI, Altman told CNN in 2015 he wanted to steer the path of AI, rather than worrying about the potential harms and doing nothing. OpenAI CEO Sam Altman addresses a speech during a meeting at Station F in Paris on May 26.

☆ Why we don't have fusion power plants yet, and what it'll take to get clean, limitless energy to market
▼ + stars: | 2023-10-29 | by ( Jenny Mcgrath | ) www.businessinsider.com time to read: +9 min

Two experts explain how long it could take until fusion power plants are possible. Fusion plants could theoretically produce almost 4 million times as much energy as burning coal or oil — with none of the carbon emissions. It's what Andrew Christlieb, who is part of a US Department of Energy fusion project at Michigan State University, calls "step zero." The US Department of Energy's Fusion Energy Sciences program has a $763 million budget for 2023, which could grow to over $1 billion next year. Achieving commercial fusion power in two decades won't be quick enough to address many countries' goals of adapting clean energy and limiting global warming by 2035.

They wanted to investigate the rocks that may contain insights about the contents locked within Earth’s core and mantle, the mostly solid layer of Earth’s interior located beneath its surface. Helium inherited from the solar nebula likely became locked in Earth’s core as the planet formed, making the core a reservoir of noble gases. “So, the helium we measured in these rocks would have escaped the core perhaps 100 million years ago or possibly much earlier.”Helium leaking from Earth’s core doesn’t affect our planet or have any negative implications, he said. If so, have fluxes of these elements from the core over (Earth’s) history influenced planetary evolution? I am excited to investigate links between helium and other light elements,” Horton said.

It's an old Silicon Valley philosophy packaged anew: Growth without guardrails. Silicon Valley enters the age of e/accAndreessen and other prominent Silicon Valley figures such as Y Combinator president Garry Tan have quietly added the term e/acc to their social media profiles. In his manifesto, Andreessen calls it "techno-optimism." To some extent, it's a repackaging of what Silicon Valley has always peddled — let us build, grow, and make money without limitations. "Techno-optimists believe growth is progress," Andreessen argues, adding that growth is driven by the progress of technology without hindrance.

There are 118 elements that make up the Periodic Table, organized by their atomic number — the number of protons in the element's atomic nucleus. For their new study, researchers from the University of Arizona, suggest that asteroid 33 Polyhymnia might contain never-before-seen material that reaches that exact threshold. It "would have a density between 36.0 and 68.4 g/cm3: a range that approaches the expected value for asteroid Polyhymnia," according to a press release. The densest element on Earth can't compareAsteroid 33 Polyhymnia might be what's called a compact ultradense object, or CUDO. These objects are thought to have densities far greater than the density of anything on Earth and therefore contain elements scientists have yet to discover.

STOCKHOLM (AP) — Swedish media say the Royal Swedish Academy of Sciences may have announced the winners of this year’s Nobel Prize in chemistry prematurely. Public broadcaster SVT said the academy sent a press release by mistake early Wednesday that contained the names of the winners. The press release said the prize went to three U.S.-based scientists for the “discovery and synthesis of quantum dots,” according to SVT. On Monday, Hungarian-American Katalin Karikó and American Drew Weissman won the Nobel Prize in medicine for discoveries that enabled the creation of mRNA vaccines against COVID-19. The chemistry prize means Nobel season has reached its halfway stage.

Only the fifth woman to win a Nobel physics prize, French-born L'Huillier works at Lund University in Sweden, while Agostini, who was also born in France, is a emeritus professor at Ohio State University in the United States. Agostini and Krausz then demonstrated how this could be used to create shorter light pulses than previously possible. These experiments all showed that attosecond pulses could be observed and measured, and could be used in new experiments. While the award for peace can take the limelight, the physics prize has also often taken centre stage with winners such as Albert Einstein and awards for science that has fundamentally changed how we see the world. Announced on consecutive weekdays in early October, the physics prize announcement will be followed by ones for chemistry, literature, peace and economics, the latter a later addition to the original line-up.

CNN —The 2023 Nobel Prize in physics has been awarded to a team of scientists who created a ground-breaking technique using lasers to understand the extremely rapid movements of electrons, which were previously thought impossible to follow. “An attosecond is to one second as one second is to the age of the universe,” the committee explained. Pierre Agostini, Ferenc Krausz and Anne L'Huillier shared this year's physics prize. Rapid movements blur together, making extremely short events impossible to observe. Electrons’ movements in atoms and molecules are so rapid that they are measured in attoseconds.

Antimatter is the enigmatic twin of ordinary matter, possessing the same mass but with an opposite electrical charge. Under current theory, the Big Bang explosion that initiated the universe should have produced equal amounts of matter and antimatter. However, antimatter can be synthesized under controlled conditions, as in the ALPHA experiment, which used antihydrogen created at CERN. "The nearly complete absence of naturally occurring antimatter is one of the great questions facing physics," Wurtele said. "No matter how pretty the theory, physics is an experimental science," Fajans said.

But just seven years after dropping the atomic bombs, the United States detonated an even more powerful nuclear weapon: the hydrogen bomb. A hydrogen bomb, also known as a thermonuclear bomb, can create explosive force hundreds or even thousands of times greater than an atomic bomb. That extra challenge is why it took scientists longer to build a hydrogen bomb than the atomic bomb. Some physicists, including Oppenheimer, who were concerned about the far greater destructive potential of hydrogen bombs compared to atomic bombs, opposed their development. Hydrogen bomb tests were incredibly powerfulOn November 1, 1952, the US detonated the first hydrogen bomb at Enewetak atoll in the Marshall Islands.
