VR headsets can be hacked with an Inception-style attack
In the Christoper Nolan movie Inception, Leonardo DiCaprio’s character uses technology to enter his targets’ dreams to steal information and insert false details into their subconscious.
A new “inception attack” in virtual reality works in a similar way. Researchers at the University of Chicago exploited a security vulnerability in Meta’s Quest VR system that allows hackers to hijack users’ headsets, steal sensitive information, and—with the help of generative AI—manipulate social interactions.
The attack hasn’t been used in the wild yet, and the bar to executing it is high, because it requires a hacker to gain access to the VR headset user’s Wi-Fi network. However, it is highly sophisticated and leaves those targeted vulnerable to phishing, scams, and grooming, among other risks. Read the full story.

How rerouting planes to produce fewer contrails could help cool the planet
What’s happening: A handful of studies have concluded that making minor adjustments to the routes of a small fraction of airplane flights could meaningfully reduce global warming. Now a new paper finds that these changes could be pretty cheap to pull off as well.
How it works: Jets release heat, water vapor, and particulate matter that can produce thin clouds in the sky, known as “contrails”. When numerous flights pass through such areas, these contrails can form clouds that absorb radiation escaping from the surface, acting as blankets floating above the Earth.
Why it matters: A small fraction of overall flights, between 2% and 10%, create about 80% of the contrails. So the growing hope is that simply rerouting those flights could significantly reduce the effect, presenting a potentially high leverage, low cost and fast way of easing warming. Read the full story.

LLMs become more covertly racist with human intervention
The news: Since their inception, it’s been clear that large language models like ChatGPT absorb racist views from the millions of pages of the internet they are trained on. Developers have responded by trying to make them less toxic. But new research suggests that those efforts are only curbing racist views that are overt, while letting more covert stereotypes grow stronger and better hidden. And it’s a problem that grows as these models get bigger and bigger.
How they did it: Researchers asked five AI models to make judgments about speakers who used African-American English (AAE). The race of the speaker was not mentioned in the instructions. Even when the two sentences had the same meaning, the models were more likely to apply adjectives like “dirty,” “lazy,” and “stupid” to speakers of AAE than speakers of Standard American English.

The big story
The quest to learn if our brain’s mutations affect mental health
Scientists have so far been unable to link brain disorders, such as autism and Alzheimer’s disease, to an identifiable gene.
But a University of California, San Diego study published in 2001 suggested a different path. What if it wasn’t a single faulty gene—or even a series of genes—that always caused cognitive issues? What if it could be the genetic differences between cells?
The explanation had seemed far-fetched, but researchers are belatedly starting to take it seriously. Read the full story.
