All 5 Key Ingredients of OUR DNA have been Found in Meteorites that came from Outer Space

Posted by in categories: biotech/medical, chemistry

The study was undertaken by Yasuhiro Oba’s team from Hokkaido University in Japan and astrochemists at NASA. A few years ago, Oba developed a technique to delicately excavate and separate different chemical compounds found in meteorite dust.

Using their mild extraction technique that uses cold water instead of acids, scientists found life-creating bases and compounds in four meteorite samples from Australia, US state of Kentucky, and Canadian province of British Columbia.

The discovery of these compounds in meteorites means that it is possible life on Earth as it stands today was created by compounds that came from outer space.

Bill Gates proposal to monitor disease outbreaks could cost $1 billion a year

Posted by in categories: biotech/medical, surveillance

Bill Gates, the Microsoft founder turned philanthropist, has called for a global response team to be set up to carry out surveillance for pathogens that can potentially ring in the next pandemic, Financial Times reported.

Long before COVID-19 struck, Gates warned the world of an imminent pandemic and the need to prepare ourselves to face it. Gates has been vocal about the long delays involved in the vaccine development process and the lack of equity in vaccine distribution in the world. So far, he has also been right about how the COVID-19 pandemic will play out and has pandemic avoiding strategies in his new book.

ChatGPT may be coming for our jobs. Here are the 10 roles that AI is most likely to replace

Posted by in categories: employment, robotics/AI

Media jobs across the board — including those in advertising, technical writing, journalism, and any role that involves content creation — may be affected by ChatGPT and similar forms of AI, Madgavkar said. That’s because AI is able to read, write, and understand text-based data well, she added.

“Analyzing and interpreting vast amounts of language based data and information is a skill that you’d expect generative AI technologies to ramp up on,” Madgavkar said.

Economist Paul Krugman said in a New York Times op-ed that ChatGPT may be able to do tasks like reporting and writing “more efficiently than humans.”

Google invests $300 million in Anthropic as race to compete with ChatGPT heats up

Posted by in categories: robotics/AI, security

Check out all the on-demand sessions from the Intelligent Security Summit here.

According to new reporting from the Financial Times, Google has invested $300 million in one of the most buzzy OpenAI rivals, Anthropic, whose recently-debuted generative AI model Claude is considered competitive with ChatGPT.

According to the reporting, Google will take a stake of around 10% and Anthropic will be required to use the money to buy computing resources from Google Cloud. The new funding will value the San Francisco-based company at around $5 billion.

Coming soon: A tabletop chiral attosecond laser

Posted by in category: particle physics

When molecules form from many atoms, the atoms can combine in different ways. Two forms of the same molecule can have the same composition but have different arrangements of atoms, giving rise to isomers. Some isomers may have structures that are mirror images of each other. Such molecules are called chiral molecules. Scientists are interested in studying such molecules, for example, penicillin, because one arrangement can be a lifesaver while the other could be fatal!

Researchers shine extremely short pulses of light on molecules to take their videos during the processes of interest so that they can study the structure or formation of the molecule. The pulses are so short that they are measured in attoseconds. An attosecond is a billionth of a billionth of a second.

The light needs to be what is called circularly polarised to study chiral molecules. Different arrangements of a chiral molecule respond differently to circularly polarised light, making it possible to distinguish each arrangement. Though polarised attosecond pulses are a great tool for studying chiral molecules, generating such light pulses can be daunting, expensive, and needs bulky apparatus.
