Unlocking the Secrets of Planet Formation: First Observations with the James Webb Space Telescope

Posted by in categories: alien life, evolution, physics

Can planets form under extreme conditions, such as high levels of ultraviolet radiation? This is something a recent study published in The Astrophysical Journal Letters hopes to find out as a team of international researchers used data obtained from NASA’s James Webb Space Telescope (JWST) as part of the eXtreme Ultraviolet Environments (XUE) JWST program to study the formation and evolution of young planetary systems. This particular study, known as XUE 1, focuses on the star cluster Pismis 24, with the team identifying some key ingredients for life as we know it.

“We find that the inner disk around XUE 1 is remarkably similar to those in nearby star-forming regions,” said Dr. Rens Waters, who is a professor of astrophysics at Radboud University in the Netherlands and a co-author on the study. “We’ve detected water and other molecules like carbon monoxide, carbon dioxide, hydrogen cyanide, and acetylene. However, the emission found was weaker than some models predicted. This might imply a small outer disk radius.”

AI Can Recreate Images From Human Brain Waves With ‘Over 75% Accuracy’

Posted by in categories: quantum physics, robotics/AI

Scientists were reportedly able to use artificial intelligence (AI) to reconstruct images solely from people’s brain activity with over 75% accuracy for the first time ever.

According to Japanese newspaper The Mainichi, recreating images from brain activity is usually only possible when a subject is actually seeing the images with their own eyes, or when the type of images, such as faces, letters or simple figures, were specified.

However, a team of researchers at the National Institutes for Quantum Science and Technology (QST) in Japan have now demonstrated that it’s possible to accurately reconstruct complex images with AI — based almost solely from a person’s thoughts.

Can Palmer Luckey Reinvent the U.S. Defense Industry?

Posted by in category: military

Military tech startup Anduril Industries is shaking up the U.S. defense industry as it is one of the few privately held technology companies finding success as a Defense Department contractor. But what makes the company’s software so unique that it is being used across multiple branches of the U.S. military and in both the Russia-Ukraine War and Israel-Hamas War?

WSJ explains how this startup is operating in order to disrupt the U.S. defense industry.

AI experts are roasting the NYT list of ‘who’s who’ in AI for having zero women

Posted by in category: robotics/AI

The New York Times’ profile of “who’s who” in AI, published Sunday, has drawn criticism for featuring zero women.

The article gives credit to a list of twelve men — most of them are the leaders of AI companies and tech giants — for fuelling the rise of the modern AI movement.

“You could come up with no women ⁦@nytimes⁩? I have binders of them starting with @drfeifei,” wrote tech journalist Kara Swisher in an X post on Sunday, referring to Stanford professor Fei-Fei Li.

Zhurong rover detects mysterious polygons beneath the surface of Mars

Posted by in categories: robotics/AI, space

China’s Zhurong rover was equipped with a ground-penetrating radar system, allowing it to peer beneath Mars’s surface. Researchers have announced new results from the scans of Zhurong’s landing site in Utopia Planitia, saying they identified irregular polygonal wedges located at a depth of about 35 meters all along the robot’s journey.

The objects measure from centimeters to tens of meters across. The scientists believe the buried polygons resulted from on Mars billions of years ago, but they could also be volcanic, from cooling lava flows.

The Zhurong rover landed on Mars on May 15, 2021, making China the second country ever to successfully land a rover on Mars. The cute rover, named after a Chinese god of fire, explored its , sent back pictures—including a selfie with its lander, taken by a remote camera—studied the topography of Mars, and conducted measurements with its ground penetrating radar (GPR) instrument.

New algorithm finds lots of gene-editing enzymes in environmental DNA

Posted by in categories: biotech/medical, food, genetics, information science

CRISPR—Clustered Regularly Interspaced Short Palindromic Repeats—is the microbial world’s answer to adaptive immunity. Bacteria don’t generate antibodies when they are invaded by a pathogen and then hold those antibodies in abeyance in case they encounter that same pathogen again, the way we do. Instead, they incorporate some of the pathogen’s DNA into their own genome and link it to an enzyme that can use it to recognize that pathogenic DNA sequence and cut it to pieces if the pathogen ever turns up again.

The enzyme that does the cutting is called Cas, for CRISPR associated. Although the CRISPR-Cas system evolved as a bacterial defense mechanism, it has been harnessed and adapted by researchers as a powerful tool for genetic manipulation in laboratory studies. It also has demonstrated agricultural uses, and the first CRISPR-based therapy was just approved in the UK to treat sickle-cell disease and transfusion-dependent beta-thalassemia.

Now, researchers have developed a new way to search genomes for CRISPR-Cas-like systems. And they’ve found that we may have a lot of additional tools to work with.
