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.

What implications do you see for content moderation, privacy, and fake video generation and detection?

Should this approach be used in social media platforms, or are there limitations we should consider?

Into its component molecules.

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?

Thanks for addin gthat, yes absolutely right!

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?
