NASA sheds light on a massive supernova dating back to Middle Ages

The supernova is so old that it is believed to have been described in a passage of Shakespeare’s “Hamlet.”

A group of scientists has shed new light on a star that exploded in a supernova more than 450 years ago, blasting particles out into space at close to the speed of light.

Now, astronomers have used NASA’s Imaging X-ray Polarimetry to study the incredibly long-lasting aftereffects of the supernova called Tycho.

The Tycho supernova blast released as much energy as the Sun would emit over ten billion years, NASA pointed out in a statement. The blast was visible to many humans on Earth way back in 1572.

Physically active men at work are more fertile, a Harvard study confirms

Men who regularly lift heavy objects at work have almost 50 percent higher sperm concentration and count.

As infertility is becoming a common problem of late, and medical professionals are scrambling to find solutions to nullify this rising trend. Researchers have found a link between male fertility and occupational factors, such as physical demands and work schedules.

The Harvard Medical School (HMS) and Brigham and Women’s Hospital collaborative effort found that men who “regularly lift heavy objects at work have higher sperm counts than men whose work is less physically demanding,” a press release said.

Here is the perfect 11-minute rule for a long-lasting healthy life

Give at least 11 minutes to your body, and it could do wonders for you.

Cambridge University researchers propose that people can reduce their risk of early death from heart disease, cancer, and various other health problems — just by doing 11 minutes of brisk walking or any other moderate-intensity physical activity daily.

This is half the effort that National Health Service (NHS) recommended in the past to lead a long and healthy life. According to NHS, a person between 19 to 64 years of age should spend at least 150 minutes a week (about 21 hours a day) doing moderate-intensity exercise.

Elon Musk plans chatbot to combat Microsoft ‘controlled’ ChatGPT

The business magnet is trying to hire an AI expert who recently left Alphabet, Google’s parent company.

Elon Musk is working on a “new research lab to develop an alternative to ChatGPT,” OpenAI’s chatbot, which he co-founded earlier and later “cut ties” with.

The tech billionaire has reached out to AI researchers in recent weeks to develop a ChatGPT “alternative,” The Information, a technology news website, reported on Monday, citing sources close to the matter.

Tesla Superchargers will now charge non-Tesla electric vehicles

It took a while, but better late than never.

Tesla has now begun to provide non-Tesla electric vehicle owners in the U.S. with access to some Supercharger stations and has also explained how the stations work, Electrek.

The Superchargers stations are outfitted with an integrated CCS adapter that works with non-Tesla EVs. However, the stations are not available on the app. Nor have the owners of electric vehicles been onboarded.

Tesla is expanding production capacity of power electronics components that convert alternating current to direct current, charging cabinets, posts, and cables.

Generative AI ChatGPT As Masterful Manipulator Of Humans, Worrying AI Ethics And AI Law

Those masterful manipulators. We’ve all dealt with those manipulative personalities that try to convince us that up is down and aim to gaslight us into the most unsettling of conditions. They somehow inexplicably and unduly twist words. Their rhetoric can be overtly powerful and overwhelming. You can’t decide what to do. Should you merely cave in and hope that the verbal tirade will end? But if you are played into doing something untoward, acquiescing might be quite endangering. Trying to verbally fight back is bound to be ugly and can devolve into even worse circumstances.

It can be a no-win situation, that’s for sure.

Now that I’ve covered some of the principle modes of AI and human manipulation, we can further unpack the matter. In today’s column, I will be addressing the gradually rising concern that AI is increasingly going to be manipulating us. I will look at the basis for these qualms. Furthermore, this will occasionally include referring to the AI app ChatGPT during this discussion since it is the 600-pound gorilla of generative AI, though do keep in mind that there are plenty of other generative AI apps and they generally are based on the same overall principles.

Meanwhile, you might be wondering what in fact generative AI is.

Let’s first cover the fundamentals of generative AI and then we can take a close look at the pressing matter at hand.

ChatGPT Won’t Fix Healthcare, But It Might Save Doctors Some Time

In a healthcare industry still burdened with 1960s technology, generative AI may offer a little relief — but companies are still working to overhaul a broken system that’s keeping doctors and nurses more focused on paperwork than patients.

Every week, Eli Gelfand, chief of general cardiology at Beth Israel Deaconess Medical Center in Boston, wastes a lot of time on letters he doesn’t want to write — all of them to insurers disputing his recommendations. A new drug for a heart failure patient. A CAT scan for a patient with chest pain. A new drug for a patient with stiff heart syndrome.

Classiq, Microsoft Team on Quantum Computing for Academia

In an interview with EE Times, Classiq CEO Nir Minerbi said Classiq’s academic program is an essential part of its broader strategy to expand the platform’s reach and promote the quantum computing business.

“We believe that offering this program will give students the tools and knowledge they need to learn practical quantum software-development skills while also providing researchers with a streamlined means of developing advanced quantum computing algorithms capable of taking advantage of ever more powerful quantum hardware,” he said. “In addition, our program enables students and researchers to test, validate and run their quantum programs on real hardware, providing valuable real-world experience. Ultimately, we think that our academic program will have a significant impact on the quantum computing community by promoting education and research in the field—and helping to drive innovation and progress in the industry.”

Classiq and Microsoft are among the top companies developing quantum computing software. The quantum stack developed by the firms advances Microsoft’s vision for quantum programming languages, which was published in the 2020 issue of Nature.

People can learn to detect AI writing

Another week, another AI chatbot.

This week Snapchat launched My AI, a customised version of OpenAI’s ChatGPT and Elon Musk signalled his intentions to build one.

Artificial intelligence (AI) writing technology underpinned by large language models are certainly impressive. And they are creating a great deal of anxiety among writers, academics and people concerned about intellectual property rights.

A “runaway” supermassive black hole is hurtling through the universe at an astonishing speed

For the last 50 years, astronomers have speculated that some supermassive black holes might “run away” from their home galaxies given the right conditions. Now, astronomers believe they have discovered a strong candidate for a supermassive black hole that has done just that, according to new research published on the preprint server arXiv.org, which has been accepted for publication in The Astrophysical Journal.
