Scientists use chemical mapping to study the spiraling arms of the Milky Way

Posted by in categories: chemistry, evolution, mapping, space

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.

Hydrogen from sunlight: US researcher set conversion efficiency record

Posted by in categories: chemistry, energy, engineering, transportation

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 world’s fastest supercomputer with a processing power of 4 exaflops unveiled

Posted by in categories: business, robotics/AI, space, supercomputing

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.

Origami-inspired folding solar-powered light that charges your phone

Posted by in categories: mobile phones, sustainability

Innovative solar-powered light has helped earthquake victims around the world and now comes with phone-charging function.

As a little girl growing up in Seoul, Korea and then upstate New York, inventor Alice Min Soo Chun spent days with her mother learning origami and how a simple fold could become structured.

She went on to study Architecture at Penn State and earned her Masters at the University of Pennsylvania.

New GPS study shows promise for 2-hour earthquake prediction signal

Posted by in category: futurism

Scientists may have taken a significant step toward earthquake prediction, according to a recent study published in Science.

By analyzing GPS time-series data from almost 100 large earthquakes worldwide, they revealed evidence of a potential precursory phase that occurs 2 hours before a seismic rupture.

A ‘toolbox of biocatalysts’ improves control over free radicals

Posted by in category: chemistry

One of the central challenges for synthetic chemists is to impose control over free radicals. Highly reactive molecules with an unpaired electron, free radicals, may be familiar to you; these are the type of molecules we take antioxidant supplements for, in an effort to tame oxidative stress.

In the world of synthetic , however, hold a lot of promise.

“Free chemistry is very useful for the synthesis of both bioactive small molecules and everyday polymers,” said UC Santa Barbara chemistry professor Yang Yang, an author of a paper on the matter that appears in Nature Catalysis. “However, imposing stereocontrol over free-radical mediated reactions has eluded the asymmetric catalysis community for decades. We’re trying to develop biocatalytic strategies to further push the boundaries of free radical chemistry.”

Cerebras Systems signs $100 million AI supercomputer deal with UAE’s G42

Posted by in categories: robotics/AI, space, supercomputing

July 20 (Reuters) — Cerebras Systems on Thursday said that it has signed an approximately $100 million deal to deliver the first of what could be up to nine artificial intelligence (AI) supercomputers in a partnership with United Arab Emirates-based technology group G42.

The deal comes as cloud computing providers around the world are searching for alternatives to chips from Nvidia Corp (NVDA.O), the market leader in AI computing whose products are in short supply, thanks to the surging popularity of ChatGPT and other services. Cerebras is one of several startups looking to challenge Nvidia.

Silicon Valley-based Cerebras said that G42 has agreed to purchase three of what it calls its Condor Galaxy systems, all of which it will build in the U.S. to speed up the roll out. The first one will come online this year, with two more coming in early 2024.
