- llama-sleep reduced model swap time to 1.7 seconds
llama-sleep preserves prompt cache in RAM instead of GPU, reducing model swap time from 10.3 to 1.7 seconds using transparent huge pages.
- Sleep-time compute allows AI agents to consolidate memory
Researchers at Letta and UC Berkeley proposed using idle time between interactions to consolidate memory, similar to the brain's sleep consolidation process.
- AI Frontiers group is over
Researcher John Langford announced the closure of the AI Frontiers group, which focused on building reliable AI agents like Autogen and Fara.
- Genetically engineered muscles power water-swimming robot
MIT engineers developed a thin robot with fins covered in genetically engineered muscle cells that twitch in response to light. This biological layer provides enough force for the device to swim and maneuver through water.
- RL Judge improves models' reasoning
The study demonstrates that using agentic judges in reinforcement learning enables models to learn efficient reasoning processes, not just correct outcomes, contrasting with traditional methods.
- Participants with prediabetes lost weight faster after falling asleep
A study from New York University found that falling asleep earlier, rather than sleeping longer, is a key factor for weight loss and metabolic health. Participants with prediabetes showed this connection between early sleep onset and improved outcomes.
- Phase 3 trial showed no difference in outcomes
The pelacarsen drug successfully reduced Lp(a) levels, yet the HORIZON trial showed no reduction in heart attacks, strokes, or deaths over nearly five years.
- New model Arete-27B reinforces Western values
The Arete-27B model is a post-trained version of Alibaba's Qwen3.8-27B, adapted to promote Western values on a Chinese base model. Authors highlight the risk of viewpoint homogeneity in current AI labs.
- 72 men with sleep apnea had lower semen volume
A study found that men with obstructive sleep apnea had lower semen volume and reduced sperm motility due to nighttime hypoxia. Treatment of 25 participants improved these reproductive metrics.
- The Semtech LR2021 chip now supports custom firmwares
Researchers extracted a hidden microcontroller from the Semtech LR2021 chip and successfully updated its firmware, enabling on-chip FFT processing and mesh network node control.
- New drug failed to reduce heart attack deaths
The ZEUS study found that ziltivekimab reduced interleukin-6 levels without decreasing heart attacks, strokes, or deaths. Novo Nordisk halted two additional trials, yet cardiologists plan to pursue anti-inflammatories for cardiovascular and metabolic disease.
- Two experts demonstrated how proteomics measures aging pace
The study showed that semaglutide caused cardiometabolic and inflammatory protein changes that persisted after the drug was stopped.
- Astronomers detect toxic hydrogen chloride on Mars
Astronomers identified noxious hydrogen chloride (HCl) near Alba Mons, suggesting the planet's interior is still undergoing igneous processes.
- SmolLM2 forecast works on Kindle processor
A custom Alpine Linux distribution was installed on the 7th generation Kindle PaperWhite 3, featuring a local SmolLM2 chatbot running on the device's processor.
- Each robot will get a tamper-proof digital ID card
China's Ministry of Industry and Information Technology has drafted rules requiring a tamper-proof, lifetime identification code for every complete robot made in China. Manufacturers must register each product's components and software on a ministry-overseen platform before the robot leaves the factory.
- Google Messages turns off notifications for old apps
Google Messages enables features that may hinder convenience: auto-responders, hiding sender names, and new chat notifications. The article lists specific settings to disable for better control over message flow.
- Solar panel efficiency could reach 43 percent
A new method developed by ICFO researchers overcomes energy loss through emission, enabling a projected efficiency of approximately 43 percent, surpassing the 33.16 percent Shockley-Queisser limit.
- Furnaces found at Great Zimbabwe were arm-span wide
Researchers reconstructed the method for smelting iron at 2,100°F using natural-draft furnaces that required no human labor.
- Amazon's new Kindle lineup is $40 more expensive
New Kindle Paperwhite and Colorsoft models cost $40–$50 more due to AI-driven chip shortages, while the entry-level device remains the most affordable option.
- The YAP1 protein promotes cell migration when activated in cancer cells
MIT researchers identified the YAP1 pathway, triggered by ceramides produced from a high-fat diet, as essential for colorectal cancer cells to metastasize to the liver.
