Drone show accidents highlight the challenges of maintaining safety in what engineers call “multiagent systems” — systems of multiple coordinated, collaborative, and computer-programmed agents, such as robots, drones, and self-driving cars.

Now, a team of MIT engineers has developed a training method for multiagent systems that can guarantee their safe operation in crowded environments. The researchers found that once the method is used to train a small number of agents, the safety margins and controls learned by those agents can automatically scale to any larger number of agents, in a way that ensures the safety of the system as a whole.

Thermoelectric generators played a major role in this experiment.


An experimentator has used waste heat of his body to turn humans into batteries. Nick Zetta, who runs Basically Homeless YouTube channel, turned himself into a battery using thermoelectric generators.

Zetta followed a simple approach that aimed at capturing the waste heat from the human body and turning that into electricity.

In today’s AI news, When rivals take a different approach and succeed, it sometimes pays to change course. This is what Sam Altman said OpenAI will do, according to a Reddit AMA session on Friday. Altman was asked about DeepSeek, which has taken the tech world by storm after rolling out top-performing AI models that are relatively cheap to use.

Then, Andreessen Horowitz general partner and Mistral board member Anjney “Anj” Midha first spied DeepSeek’s jaw-dropping performance six months ago. That’s when DeepSeek introduced Coder V2, which rivaled OpenAI’s GPT4-Turbo for coding-specific tasks, according to a paper it released last year.

S V3 and R1 models. These efforts “achieved significant bypass rates, with little to no specialized knowledge or expertise being necessary.” ‘ + And, MLCommons, a nonprofit AI safety working group, has teamed up with AI dev platform Hugging Face to release one of the world’s largest collections of public domain voice recordings for AI research. The dataset, called Unsupervised People’s Speech, contains more than a million hours of audio spanning at least 89 languages.

In videos, in this episode of “How To Build The Future,” YC President and CEO Garry Tan sits down with Bob to discuss the lessons learned from his time at OpenAI, scaling laws, his advice for startups, and what all of this means for the jobs of the future.

Then, “Maybe I Got Carried Away” is an experimental short film that fuses playful visuals with a surreal narrative. It was created by [@panaviscope](https://www.youtube.com/@panaviscope) using Sora generated shots. The story follows a protagonist who begins releasing vibrant balloons into the sky as a personal act of rebellion against her city’s monotony.

Scientists have harnessed many-body physics to transform quantum dots into scalable, stable quantum nodes. By entangling nuclear spins into a ‘dark state,’ they created a quantum register capable of storing and retrieving quantum information with high fidelity. This leap forward brings quantum networks closer to reality, unlocking new possibilities for communication and computing.

Treating hair loss may be as simple as developing therapies to flip a molecular “switch,” according to a new study by researchers from Penn State; the University of California, Irvine; and National Taiwan University.

The researchers reviewed the biological and social evolution of human scalp hair. Based on their analysis, they proposed a novel theory that points to a molecular basis underlying the ability to grow long scalp hair.

In short, human ancestors may have always had the ability to grow long scalp hair, but the trait remained dormant until certain environmental and biological conditions — like walking upright on two legs — turned on the molecular program. The team published their findings, which they said could serve as the basis for future experimental work, in the British Journal of Dermatology.

Researchers at the University of Oxford and their collaborators, including the Serum Institute of India, have developed an innovative method to identify falsified vaccines without opening the vaccine vial.

The new method, published in npj Vaccines, analyzes the vial label and its adhesive and therefore allows the vaccine vials to be retained in the supply chain. Furthermore, the study has shown that the technique can also differentiate genuine COVID-19 vaccine liquid from falsified vaccine surrogates, using a recently published method developed using non-COVID vaccines.

The World Health Organization (WHO) estimates that 10.5% of medicines worldwide in low and middle-income countries are substandard or are falsified medicines made by criminals. This threatens global health since the medicines and vaccines fail to prevent and treat the diseases for which they were intended, and they risk additional adverse health consequences if the ingredients used by criminals in the falsified products are harmful.
