Generative AI ‘fools’ scientists with artificial data, bringing automated data analysis closer

Posted by in categories: materials, robotics/AI

The same AI technology used to mimic human art can now synthesize artificial scientific data, advancing efforts toward fully automated data analysis.

Researchers at the University of Illinois Urbana-Champaign have developed an AI that generates artificial data from microscopy experiments commonly used to characterize atomic-level material structures. Drawing from the technology underlying art generators, the AI allows the researchers to incorporate and experimental imperfections into the generated data, allowing material features to be detected much faster and more efficiently than before.

The study, “Leveraging generative adversarial networks to create realistic scanning transmission electron microscopy images,” was published in the journal npj Computational Materials.

Revealing the invisible: Detecting variations in extragalactic magnetic fields

Posted by in categories: cosmology, evolution, particle physics

Magnetic fields are common throughout the universe but incredibly challenging to study. They don’t directly emit or reflect light, and light from all along the electromagnetic spectrum remains the primary purveyor of astrophysical data. Instead, researchers have had to find the equivalent of cosmic iron filings—matter in galaxies that is sensitive to magnetic fields and also emits light marked by the fields’ structure and intensity.

In a new study published in The Astrophysical Journal, several Stanford astrophysicists have studied infrared signals from just such a material—magnetically aligned dust grains embedded in the cold, dense clouds of star-forming regions. A comparison to light from cosmic ray electrons that has been marked by magnetic fields in warmer, more diffuse material showed surprising differences in the measured magnetic fields of .

Stanford astrophysicist and member of the Kavli Institute for Particle Acceleration and Cosmology (KIPAC) Enrique Lopez-Rodriguez explains the differences and what they could mean for galactic growth and evolution.

Doctors re-attach boy’s head post-car accident with ‘amazing’ surgery

Posted by in category: biotech/medical

Doctors in Israel have re-attached a boy’s head after he was hit by a car while riding his bike.

Twelve-year-old Palestinian Suleiman Hassan, from the West Bank, suffered an internal decapitation — where the base of the skull and the top of the spine become detached, but the skin is still intact.

Decapitation is the total separation of the head from the body. Internal decapitation occurs when sudden impact to the head causes the ligaments and muscles holding the skull in position on the top vertebrae of the spine to tear.

We can’t predict the future, but appreciating its uncertainties will make us happier

In it, he explores how we can make better, scientifically informed predictions about the world around us, using maths. “Mathematics can provide us with the objective tools to bypass the foibles of our own biology – the limitations imposed by our own thought processes, the compulsions that ultimately make us human, but let us down when it comes to making inferences about the world around us,” he writes. “They are humanity’s shortcuts: the preconceptions and cognitive biases, refined over millennia of evolution, that all too often lead us astray when we try to apply our brain’s old rules to our society’s new environments.”

No matter how tempting it is to think, “Ooh, that’s a bit spooky” when faced with a completely random coincidence or chance occurrence, we should all be expecting unusual things to happen all the time, he says.

Yates describes a person who, when browsing in a secondhand bookshop far from where they grew up, opens a copy of their favourite children’s book, only to find their own name inscribed inside. Yet, he says, “the law of truly large numbers” dictates that, just as someone wins the lottery almost every week, with enough opportunities, such extraordinary coincidences are far more likely to happen than you might think. “There are so many different types of coincidences that make us say: ‘Well, that’s extraordinary.’ But it’s not unlikely that some of them happen to us every so often.”

PPP fraud is ‘worst in history’: $200B stolen and blown on Lamborghinis, beach houses and bling

Posted by in categories: biotech/medical, robotics/AI

When people say there s no money for advanced AI research, robotics research, energy research, etc… etc… take a close look at who was rollin in money and buyin below items.


“The fraud was so easy to commit. All of the information was self-reported and none of it was verified or checked,” Haywood Talcove of LexisNexis Risk Solutions told The Post.

“During the height of the pandemic, it was really hard to purchase [luxury] items like a Rolls-Royce, or a high-end Mercedes because you had people walking in with cash from the PPP program to purchase those items for whatever the dealer was asking,” Talcove said.
