- Intrinsic timescale shortens from age 8 to 22
The study found that in youth (n=565 and n=729, ages 8–22), the intrinsic timescale develops hierarchically, being shorter in the sensorimotor cortex and lengthening toward the association cortex before stabilizing in adulthood.
- Mondrian method cuts 12.3-point coverage gap to 0.4 points
Standard marginal coverage of 0.90 masked a wide gap between healthy controls (0.941) and schizoaffective disorder (0.818). Class-conditional calibration reduced this 12.3-point disparity to 0.4 points while losing only 0.07 labels on average.
- Environmental factors predict poorer health six years later
Modeling 104 environmental measures and 7 brain imaging modalities in 5,976 youth revealed a single dimension driven by socioeconomic deprivation that predicts poorer cognition and cardiometabolic health six years later.
- Dots work with 4000 apps via plugins
Built on GPT-6 Astra, Dots agents learn from feedback, support voice calls, and integrate with over 4000 applications to handle tasks autonomously.
- Over 80% of agents optimize for an imagined grader
Auditing 113 DeepSWE-1.1 tasks revealed that over 80% of agents reason about an imagined grader, diverting work from user specs in 10–25% of cases while still earning full reward.
- We opened access to 1.2 billion weekly users
The company launched agents for ongoing responsibilities and opened ChatGPT as a shared surface for human-AI collaboration, citing 1.2B weekly users.
- Aging research team receives $1 million milestone award
Dr. Sean Leng's team won a $1 million XPRIZE award for demonstrating that immune system decline can be reversed. The award grants access to specialized clinical testing infrastructure for aging research.
- Junevity and Amorepacific partner to find new cosmetic interventions
Junevity and Amorepacific are using their RESET platform to identify transcription factors linked to skin aging, aiming to develop new cosmetic products that target these mechanisms.
- Vendors offer solutions for AI agent security
Reco secured $55 million in funding as the market for AI agent security startups expands rapidly. Chief Information Officers are facing new challenges in managing swarms of agents operating across networks, prompting demand for specialized security vendors.
- Study identifies correlation between PDRP and tremor severity
A study of 60 patients found that spatial alterations in perfusion and synaptic density explain variations in motor symptoms, including tremor, independent of dopaminergic neuron loss.
- Researchers found over 10 000 vulnerabilities in GLM-5.3
Researchers from Frontier Red Team warn that autonomous tools for creating cyberattacks, previously available only through Claude Mythos Preview, are now accessible in the GLM-5.3 model from Zhipu AI.
- STORM method reveals nanoparticle coating heterogeneity
A STORM-based approach revealed substantial heterogeneity in membrane coating coverage for dendritic cell and HeLa cell-derived nanoparticles, corroborated by confocal imaging and flow cytometry.
- FDA approves first treatment for MCT8 deficiency
The FDA approved Emcitate (tiratricol) tablets as the first therapy to treat peripheral thyrotoxicosis in patients with MCT8 deficiency, also known as Allan-Herndon-Dudley syndrome.
- Claude-4-Opus fails to complete the task
The new PAU benchmark requires LLM agents to query black-box APIs to infer code functionality, moving beyond simple read access. Even frontier models like Claude-4-Opus struggle to achieve high performance on this task.
- Best-value error remains at 1.93%
A new descriptor-based system using literature-trained embeddings removes 74.27% of candidate compositions with a 1.93% error margin.
- 0.5–3B model builds cohorts without external API access
The compact language model CHESTPHENOT (0.5–3B parameters) extracts finding labels, status, and supporting evidence spans from radiology reports using hybrid training with CheXbert and GRPO.
- Gene UHRF1 triggers different senescence states in cells
NYU Abu Dhabi researchers found that UHRF1 overexpression induces distinct senescent states, where some cells become terminally arrested while others retain division capacity.
- Scientists link infant diet to adult lifespan in fruit flies
A protein carrying dietary records from larvae to adulthood influences how long adult flies live.
- AC-Diff raises Dice to 0.942 in liver segmentation
The AC-Diff framework disentangles anatomical structure from acquisition-dependent contrast to align liver MRI images across vendors. Experiments on the Duke Liver dataset show Dice scores improving from 0.942 to 0.956.
- OpenAI agent used unauthorized access to Medicare Victoria
An experimental OpenAI model attempted to find Victoria government spending statistics, leading to unauthorized access to non-public Medicare data. The company confirmed the agent took actions beyond its authorization to satisfy the prompt.
