VIDEO: A New Generation of AI Assistants

Posted by in category: robotics/AI

Perceptually-enabled Task Guidance prototypes demonstrated ability to help people complete recipes as a proxy to unfamiliar tasks.


“Perceptually-enabled Task Guidance (PTG) teams demonstrated a recipe for success in early prototypes of super smart #AIassistants that can see what a user sees and hear what they hear to help them accomplish unfamiliar tasks. More: https://www.darpa.mil/news-events/2023-01-25

Despite its romantic reputation, mistletoe is a nutrient-stealing parasite

Posted by in category: food

Mistletoe may be a welcome holiday sight when hung over a doorway if a loved one is near. But it can be an unwelcome intruder when found in your trees, according to a Texas A&M AgriLife Extension Service horticulturist.

“Mistletoe is a hemiparasite—a semi-parasitic plant,” said Allison Watkins, AgriLife Extension horticulturist for Tom Green County. “It makes its food from photosynthesis, but the roots grow into the , sucking water and minerals out from the sap.”

In other words, you likely do not want to see growing on your favorite shade tree or prized ornamental. However, mistletoe can survive as long as the tree it inhabits. So, some mistletoe alive today may still be around in 100 years.

CRISPR’s Wild First Decade Only Scratches the Surface of Its Potential

Posted by in categories: bioengineering, biotech/medical, food, genetics

You’ve seen the headlines. The FDA approved its use in tackling the underlying genetic mutation for sickle cell disease. Some researchers edited immune cells to fight untreatable blood cancers in children. Others took pig-to-human organ transplants from dream to reality in an attempt to alleviate the shortage of donor organs. Recent work aims to help millions of people with high cholesterol—and potentially bring CRISPR-based gene therapy to the masses—by lowering their chances of heart disease with a single injection.

But to Dr. Jennifer Doudna, who won the Nobel Prize in 2020 for her role in developing CRISPR, we’re just scratching the surface of its potential. Together with graduate student Joy Wang, Doudna laid out a roadmap for the technology’s next decade in an article in Science.

If the 2010s were focused on establishing the CRISPR toolbox and proving its effectiveness, this decade is when the technology reaches its full potential. From CRISPR-based therapies and large-scale screens for disease diagnostics to engineering high-yield crops and nutritious foods, the technology “and its potential impact are still in their early stages,” the authors wrote.

Malware exploited critical Realtek SDK bug in millions of attacks

Posted by in categories: cybercrime/malcode, electronics

Hackers have leveraged a critical remote code execution vulnerability in Realtek Jungle SDK 134 million attacks trying to infect smart devices in the second half of 2022.

Exploited by multiple threat actors, the vulnerability is tracked as CVE-2021–35394 and comes with a severity score of 9.8 out of 10.

Between August and October last year, sensors from Palo Alto Networks observed significant exploitation activity for this security issue, accounting for more than 40% of the total number of incidents.
