AMD Ryzen 5 7500F Allegedly Coming Soon, No iGPU Support

Posted by in category: computing

The product itself is an interesting one, and seems built to hit a sweet price/performance ratio for anyone that plans on using a discrete GPU solution. Of course, the absence of an integrated GPU does limit the users’ flexibility — I can’t count the number of times I used an integrated GPU to try and pinpoint issues with my systems (and graphics cards). But the fact remains that more consumer choice is best: users can make their own decision on whether that’s worth the extra $10 or not.

Most of this information comes courtesy of Harukaze (via Twitter), as well as a benchmark on PugetBench, where the Ryzen 5 7500F was paired with an X670E motherboard and 32 GB of DDR5-4800 memory.

Astronomers witness energetic switch on of black hole

Posted by in categories: cosmology, physics

A team of astronomers led by researchers from the University of Birmingham, University College London and Queen’s University Belfast have discovered one of the most dramatic ‘switches on’ of a black hole ever seen. They will present their findings on Tuesday 4 July at the 2023 National Astronomy Meeting in Cardiff. The work will also be published in Monthly Notices of the Royal Astronomical Society.

J221951-484240, known as J221951, is one of the most luminous transients—astrophysical objects that change their brightness over a short period of time—ever recorded. It was discovered by Dr. Samantha Oates, an astronomer at the University of Birmingham, and her team, in September 2019 while searching for the electromagnetic light from a gravitational wave event. The team were using the Ultra-Violet and Optical Telescope on board the Neil Gehrels Swift Observatory to look for a kilonova, the sign of a neutron star merging with another neutron star or a black hole. A kilonova typically appears blue, then fades and turns more red in color over a timescale of days. What they found instead something even more unusual: J221951. The transient appeared blue, but didn’t change color or fade rapidly as a kilonova would.

Multiple telescopes were used to follow-up J221951 and determine its nature, including NASA’s Swift/UVOT and Hubble Space Telescope, the South African Large Telescope, and ESO facilities such as the Very Large Telescope and the GROND instrument on the MPG/ESO 2.2-meter telescope at the La Silla Observatory.

AI combined with CRISPR precisely controls gene expression

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

Artificial intelligence can predict on-and off-target activity of CRISPR tools that target RNA instead of DNA, according to new research published in Nature Biotechnology.

The study by researchers at New York University, Columbia University, and the New York Genome Center, combines a with CRISPR screens to control the expression of human in different ways—such as flicking a light switch to shut them off completely or by using a dimmer knob to partially turn down their activity. These precise gene controls could be used to develop new CRISPR-based therapies.

CRISPR is a gene editing technology with many uses in biomedicine and beyond, from treating sickle cell anemia to engineering tastier mustard greens. It often works by targeting DNA using an enzyme called Cas9. In recent years, scientists discovered another type of CRISPR that instead targets RNA using an enzyme called Cas13.

Scientists Train New AI Exclusively on the Dark Web

Posted by in categories: internet, law enforcement, robotics/AI

OpenAI’s large language models (LLMs) are trained on a vast array of datasets, pulling information from the internet’s dustiest and cobweb-covered corners.

But what if such a model were to crawl through the dark web — the internet’s seedy underbelly where you can host a site without your identity being public or even available to law enforcement — instead? A team of South Korean researchers did just that, creating an AI model dubbed DarkBERT to index some of the sketchiest domains on the internet.

It’s a fascinating glimpse into some of the murkiest corners of the World Wide Web, which have become synonymous with illegal and malicious activities from the sharing of leaked data to the sale of hard drugs.

$300,000 flying car gets special certification from FAA

Posted by in category: transportation

SAN MATEO, Calif. — A flying car being developed for both roadways and vertical takeoff and landing capabilities is now one step closer to becoming a reality after receiving a special approval from the U.S. Federal Aviation Administration.

Alef Aeronautics, based in San Mateo, California, has been developing the Model A flying car, which is 100% electric and will carry one or two occupants.

The company envisions the car, which costs roughly $300,000, saving individuals time during the commutes with the ability to fly over stopped traffic and accidents on roadways.

NASA awards Space Act Agreement contract for commercial astronaut jetpack

Posted by in categories: robotics/AI, space

The US space agency continues to look toward the private sector as it plans for life beyond the International Space Station.

NASA has awarded a Space Act Agreement contract to Special Aerospace Services (SAS) to develop a commercial version of its Autonomous Maneuvering Unit (AMU) astronaut jetpack.

The move comes as the US space agency looks ahead to a future without the International Space Station (ISS), in which private companies will build and lift a series of commercial space stations to low Earth orbit.

China builds a ‘ground space station’ to simulate diverse conditions in space

Posted by in category: space

The ground-based space station comprises multiple chambers that simulate different environments, ranging from the lunar surface to microgravity.

China has developed first-of-its-kind space station simulators to conduct various experiments and test instruments on Earth, as per the South China Morning Post (SCMP)

Reportedly, the researchers have already begun the first experimental operations of this project, known as the ground space station.
