Imagine this: a round, plump robot, like a giant bowling ball, that can roll on land, swim in water, and perform all sorts of high-tech operations. On October 9th, a team of scientists from Zhejiang University unveiled something called the RT-G spherical robot, claiming it’s a \.
Breaking oxygen out of a water molecule is a relatively simple process, at least chemically. Even so, it does require components, one of the most important of which is a catalyst. Catalysts enable reactions and are linearly scalable, so if you want more reactions quickly, you need a bigger catalyst. In space exploration, bigger means heavier, which translates into more expensive. So, when humanity is looking for a catalyst to split water into oxygen and hydrogen on Mars, creating one from local Martian materials would be worthwhile. That is precisely what a team from Hefei, China, did by using what they called an “AI Chemist.”
Unfortunately, the name “AIChemist” didn’t stick, though that joke might vary depending on the font you read it in. Whatever its name, the team’s work was some serious science. It specifically applied machine learning algorithms that have become all the rage lately to selecting an effective catalyst for an “oxygen evolution reaction” by utilizing materials native to Mars.

We’ve all been there. Moments after leaving a party, your brain is suddenly filled with intrusive thoughts about what others were thinking. “Did they think I talked too much?” “Did my joke offend them?” “Were they having a good time?”
In a new Northwestern Medicine study, scientists sought to better understand how humans evolved to become so skilled at thinking about what’s happening in other peoples’ minds. The findings could have implications for one day treating psychiatric conditions such as anxiety and depression.
RALEIGH, N.C. — Particle physicist Hitoshi Murayama admits that he used to worry about being known as the “most hated man” in his field of science. But the good news is that now he can joke about it.
Last year, the Berkeley professor chaired the Particle Physics Project Prioritization Panel, or P5, which drew up a list of multimillion-dollar physics experiments that should move ahead over the next 10 years. The list focused on phenomena ranging from subatomic smash-ups to cosmic inflation. At the same time, the panel also had to decide which projects would have to be left behind for budgetary reasons, which could have turned Murayama into the Dr. No of physics.

Even the biggest investors often make terrible trading decisions for their portfolios.
At an AI summit in Tokyo on Wednesday, Jensen Huang and Masayoshi Son joked about how SoftBank was once Nvidia’s largest shareholder before dumping its stake. The two billionaires are now joining forces on a Japanese supercomputer. SoftBank, which until early 2019 owned 4.9% of Nvidia, has secured a favorable spot in line for the chipmaker’s latest products.\r.

If you’ve recently scrolled through Instagram, you’ve probably noticed it: users posting AI-generated images of their lives or chuckling over a brutal feed roast by ChatGPT. What started as an innocent prompt – “Ask ChatGPT to draw what your life looks like based on what it knows about you” – has gone viral, inviting friends, followers, and even ChatGPT itself to get a peek into our most personal details. It’s fun, often eerily accurate, and, yes, a little unnerving.
The trend that started it all
A while ago, Instagram’s “Add Yours” sticker spurred the popular trend “Ask ChatGPT to roast your feed in one paragraph.” What followed were thousands of users clamouring to see the AI’s take on their profiles. ChatGPT didn’t disappoint – delivering razor-sharp observations on everything from overused vacation spots to the endless brunch photos and quirky captions, blending humour with a dash of truth. The playful roasting felt oddly familiar, almost like a best friend’s inside joke.

🧠 Neuromodulation through the eyes 👀
Neuroplasticity, also known as neural plasticity or brain plasticity, is a process that involves adaptive structural and functional changes to the brain.

Prefatory Note: Our usual policy at The Threepenny Review is to assign one book to one author. But in this case two of our longtime writers—P. N. Furbank, an essayist, critic, and biographer who lives in London, and Louis B. Jones, a novelist and essayist who lives in the Sierra foothills—both wanted to review the same book. So we let them. We think the results are instructive: not oppositional, not mutually contradictory, but very different approaches to the same subject. We are also pleased that neither Jones nor Furbank trained as a professional philosopher. (After all, philosophical theories, if they bear on reality, should be meaningful to the rest of us.) So here they are—first Jones, then Furbank—commenting on Thomas Nagel’s Mind and Cosmos: Why the Materialist Neo-Darwinian Conception of Nature Is Almost Certainly False, out in the fall of 2012 in both America and England from Oxford University Press.
My stranded trailer in the woods looks onto a clearing where wild sweet pea vies with starthistle, fescue with blue-eye grass and miner’s lettuce, all competing as they’ve done, possibly, since the Sierra first crumbled into soil and started inviting plants to colonize. It is a patch of ground, then, that existed through the geologic ages in the peculiar twilight oblivion of being unwitnessed—until the first Maidu people came along, probably climbing up from the creek below. Before the Maidu, the witnesses of the place were the animals. And now these days I’m here, to substantiate this little clearing’s existence. It’s almost a weary old joke in philosophy, but still a surefire, hard-to-retire joke—that I’m necessary to this clearing’s existence. My mind. The joke, however, is making a serious, small comeback in this century.
A recent study by UC San Diego researchers brings fresh insight into the ever-evolving capabilities of AI. The authors looked at the degree to which several prominent AI models, GPT-4, GPT-3.5, and the classic ELIZA could convincingly mimic human conversation, an application of the so-called Turing test for identifying when a computer program has reached human-level intelligence.
The results were telling: In a five-minute text-based conversation, GPT-4 was mistakenly identified as human 54 percent of the time, contrasted with ELIZA’s 22 percent. These findings not only highlight the strides AI has made but also underscore the nuanced challenges of distinguishing human intelligence from algorithmic mimicry.
