Google DeepMind’s New AI Matches Gold Medal Performance in Math Olympics

After cracking an unsolvable mathematics problem last year, AI is back to tackle geometry.

Developed by Google DeepMind, a new algorithm, AlphaGeometry, can crush problems from past International Mathematical Olympiads—a top-level competition for high schoolers—and matches the performance of previous gold medalists.

When challenged with 30 difficult geometry problems, the AI successfully solved 25 within the standard allotted time, beating previous state-of-the-art algorithms by 15 answers.

Scientists discover hidden army of lung flu fighters

Scientists have long thought of the fluid-filled sac around our lungs merely as a cushion from external damage. Turns out, it also houses potent virus-eating cells that rush into the lungs during flu infections.

Not to be confused with phages, which are viruses that infect bacteria, these cells are macrophages, immune cells produced in the body.

“The name macrophage means ‘big eater.’ They gobble up bacteria, viruses, , and dying cells. Really, anything that looks foreign, they take it up and destroy it,” said UC Riverside virologist Juliet Morrison, who led the discovery team. “We were surprised to find them in the lungs because nobody has seen this before, that these cells go into the lung when there’s an infection.”

Promising new therapeutic approach for treating metastatic pancreatic cancer

A research paper published in Nature Cancer details new insights into the role of efferocytosis—the burying of dead cells—in pancreatic cancer that spreads to the liver.

Liver metastasis occurs in 40–50% of people with pancreatic ductal adenosarcoma (PDAC), and there are currently no effective therapies to cure patients that have .

Led by University of Liverpool’s Professor Michael Schmid and colleagues, this study found PDAC metastases to show high levels of immunosuppressive macrophages, a type of white blood cell that promotes .

OpenAI is reportedly investing in humanoid robots

Microsoft and OpenAI are reportedly in talks to invest $100 million into robotics startup Figure — suggesting that they might hope to combine their tech with its humanoid robot.

The background: A lot of humanoid robots can look impressive in demos but turn out to be highly limited in reality.

To have a big impact in the workforce, these machines need to be not only physically capable of doing a job — a tricky enough engineering challenge — but also smart enough to tackle a huge variety of tasks with minimal training and supervision.

New Non-Opioid Drug Blocks Pain Signals Before They Can Reach Brain

As the opioid crisis worsens, one Boston-based pharmaceutical company has used some impressive biology to create what it says amounts to a non-addictive, non-opioid painkiller.

As the New York Times reports, Vertex Pharmaceuticals seems to have shown some promising results in Phase 3 clinical trials, announced earlier this week in a statement, for patients who experienced “moderate-to-severe acute pain” after getting surgery.

Whereas opioids generally target both the brain and the body, which ultimately leads to their addictiveness, non-opioid drugs like Vertex’s VX-548 focus on peripheral nerves, or those outside of the brain and spine, the NYT explains. By blocking pain at the source, the logic goes, it can be averted before reaching the brain and developing the kind of feedback loop that lends itself to dependency.

Zuckerberg slams Apple Vision Pro, says Quest 3 is better in every way

Apple’s Vision Pro may have dazzled the world with its stunning display and sleek design, but not everyone is convinced it’s the best headset on the market. One of its biggest rivals, Meta CEO Mark Zuckerberg, has some pinching words for the device and its maker.

So why is Quest 3 a better overall product according to Zuck?

Zuckerberg took to Instagram on Tuesday to share his thoughts on the Vision Pro, which he tried out for himself. He compared it to Meta’s Quest 3, the latest version of the popular standalone VR headset. He filmed the video using the Quest 3’s video passthrough feature, which lets users see the real world in color through the headset’s cameras.
