This new AI system from UC Riverside and Google can detect manipulations even when faces aren’t visible. By analyzing motion, background, and subtle inconsistencies, it tackles a growing challenge in misinformation and digital trust.

Should this approach be used in social media platforms, or are there limitations we should consider?
For example, PET plastic (used in bottles) is made of many units of ethylene glycol and terephthalic acid. The enzyme breaks the bonds linking these units, releasing the original molecules.
Why is this a good idea?
Recycling
Reduced Waste and Pollution
Reduces reliance on fossil fuels for new plastic production.
Researchers at MIT have used AI to design enzymes from scratch that can break down common plastics like PET in just hours at room temperature. This could revolutionize recycling and reduce plastic pollution dramatically.
What challenges remain for scaling this technology?
This genome sequencing uncovers unexpected Mesopotamian ancestry, shedding new light on cultural and genetic exchanges in antiquity. It’s a reminder of how interconnected ancient civilizations were, challenging common narratives of isolated populations.
How might this change our understanding of human history in the ancient world?
This discovery that newly synthesized DNA remains accessible for hours after replication opens up fascinating possibilities. Targeting this ‘hyperaccessible’ state could allow for more precise cancer treatments that selectively attack rapidly dividing cells.
It also raises questions about whether other diseases could be treated using this technology.
What challenges do you foresee in developing this into a practical therapy?
Astronomers have just detected 3I/ATLAS, only the third known interstellar comet to pass through our solar system. Discovered July 1 by the ATLAS survey in Chile, its trajectory confirms it came from beyond our solar system, following in the footsteps of ‘Oumuamua (2017) and Borisov (2019). Early estimates suggest 3I/ATLAS could be much larger than Borisov—possibly 10 km across. As it approaches the sun in October, scientists are racing to study its composition and behavior. Each interstellar visitor is a rare chance to directly sample material from another star system.
Researchers have discovered that the cowpea mosaic virus (from black-eyed peas) can activate the human immune system to attack cancer cells, without infecting human tissue.
Unlike other plant viruses, CPMV triggers a strong interferon response, making it a promising, low-cost immunotherapy. The team is moving toward clinical trials, and the approach could open a new front in cancer treatment using plant-based biotechnology.
Is this a viable treatment and can we one day stop using Chemotherapy?
No I don't even use a dew heater because it's warm here. I am imaging from Turkey where skies are blue and it does tend to be windy as I'm near the sea.
Very true mate. Fortunately, I have a very clear sky and maybe 300 plus days when it's crystal clear. It is a rabbit hole I was warned but didn't listen!
This looks like a huge step forward. Researchers from DeepMind and UCL used AI to find a more accurate 'density functional,' solving a problem that has challenged chemists for decades. The AI didn't just find a black-box solution; it discovered a new mathematical form that humans can understand and learn from. This could dramatically speed up simulations for everything from new battery materials to drug design.
As with most technology there is both a potential for harm and a potential for the positive. Knowledge can be incredibly dangerous in the wrong hands but we can't exactly unlearn things.
Hey HN, I wanted to share a video on three hardware modifications I made to my telescope that have made a night-and-day difference in my astrophotography. For a while, I felt like I'd hit a plateau with my image quality, and the issues weren't things I could fix in software. The video walks through the 'why' and 'how' of each mod:
3d printing a Bahtinov mask: To get much sharper, more consistent focus across the frame.
Flocking the tube: To dramatically increase contrast by killing stray light reflections inside the scope.
Adding light shield and baffle: To reduce stray light from entering my telescope and spoiling the images.
I tried to show the real-world results with before-and-after image comparisons. These were all relatively low-cost, DIY-friendly projects that had a much bigger impact than I expected. Happy to answer any questions about the process or the gear here!"
This is a non-invasive approach from researchers at the University of Texas at Austin that uses fMRI scans and a language model to reconstruct the 'gist' of what a person is hearing or thinking. It doesn't get a word-for-word transcript, but it captures the essence. The interesting part is that it worked even when participants were told to actively resist by thinking of other things. Raises some pretty significant privacy implications for the future.
Hi, I saw this update on NASA's EELS (Exobiology Extant Life Surveyor) robot and the engineering behind it is fascinating. It's a snake-like robot designed to explore terrain that is impossible for wheeled vehicles.
The robot will explore the icy vents on Saturn's moon Enceladus and search for signs of life. The robot has to navigate independently, using a combination of slithering and corkscrew-like movements to travel through hazardous environments deep beneath the ice.
The level of autonomy required here is what really stands out. This isn't just a remote-controlled vehicle; it's a true robotic explorer that will be light-hours away from any human intervention. It's a massive challenge in both hardware and software, especially for a mission where the stakes are this high.
