- 1Mantis shrimp packs bullet-speed punchβThe ocean's hardest-hitting boxer. A mantis shrimp's punch accelerates as fast as a .22-caliber bullet β enough force to
The mantis shrimp is drawing attention for its extraordinary strike: its punch accelerates as fast as a .22-caliber bullet, with enough force to shatter aquarium glass. The crustacean also has remarkable vision, with 12 to 16 color receptors compared with three in humans, allowing it to detect polarized light people cannot see. Science fans are sharing the facts as a striking example of extreme biology in the ocean.
- 2Simple question: how does light reach the retina's rods and cones?βEmbarrassing # question about vision and # biology of the human # eye : How does light get to rods & cones past all the
A question about basic eye biology is circulating online: how does light reach the rods and cones at the back of the retina when other cells sit in front of them? The person asking admits limited biology knowledge but understands the retina contains photoreceptors, bipolar cells and ganglion cells. The discussion highlights a genuine anatomical oddity of the vertebrate eye, where light passes through several neural layers before hitting photoreceptors.

A Nautilus essay argues that human vision has distinctive quirks and capabilities that current artificial intelligence systems cannot replicate. It examines how perception differs from machine vision models, a topic gaining attention as AI image systems become widespread.
- 4Amnesty Researcher Accuses Sudan Rebels of Child Recruitment, Sexual ViolenceβΌAmnesty Researcher Accuses Sudan Rebels Of Recruiting Children, Sexual Violence
An Amnesty International researcher has accused rebel groups in Sudan of recruiting children and committing sexual violence, according to reporting by Pan African Visions. The allegations add to mounting documentation of human rights abuses in Sudan's conflict, where armed groups have repeatedly faced accusations of exploiting minors and committing abuses against civilians.
- 5The Internet Stops: Forster's Dystopia Feels TimelyβThe Internet Stops Some thought on the slowing internet, after reading E.M. Forster's The Machine Stops https://www. ide
A Dutch blog post titled 'The Internet Stops' draws on E.M. Forster's 1909 novella The Machine Stops to reflect on the slowdown of the internet. The essay compares today's degraded, congested online experience with Forster's vision of humanity dependent on a failing machine. It is a modest, literary take on widely shared concerns about the state of the web.
- 6Documentary 'Purpose' imagines a better economy but offers no roadmapβΌDocumentary Review: βPurposeβ dreams of a better economy, but struggles to show a path to get there
A new review of the documentary "Purpose" says the film offers an inspiring vision of a more humane, purpose-driven economy, but falls short when it comes to explaining how societies could actually get there. The reviewer praises the film's ideals while criticizing its lack of concrete policy steps or practical pathways for change.
- 7UN expert urges Mozambique to avoid fossil fuel lock-inβΌMozambique needs integrated human rights vision for climate resilience and international cooperation to avoid fossil fuel lock-in, says UN expert
A UN human rights expert says Mozambique needs an integrated human rights vision to build climate resilience, coupled with international cooperation, so the country avoids becoming locked into fossil fuel dependence. The warning frames development choices around gas and other extractives as human rights and climate issues, urging partners to support alternatives that protect vulnerable communities.
- 8New font confuses AI while looking normal to humansβThis font looks perfectly normal to humans but wreaks havoc on AI
A newly designed typeface appears ordinary to human readers but causes artificial intelligence systems to misread or fail to process text set in it. The font exploits weaknesses in how AI models recognize characters, raising questions about the robustness of machine vision and text recognition, and about potential adversarial uses against automated systems.
- 9SocialVLA turns human reactions into robot intervention signalsβSocialVLA converts spontaneous human reactions into runtime intervention signals for VLA manipulation. Source: arXiv cs.
A new paper on arXiv introduces SocialVLA, a vision-language-action model that reads spontaneous human reactions and converts them into runtime intervention signals for robot manipulation. The aim is to let robots respond to natural human cues, like flinches or gestures, while working alongside people. Details of performance and real-world testing remain in the paper itself.
- 10Visual illusion exposes blind spots in AI visionβΌVisual illusion reveals what today's AI vision is missing
A visual illusion is being used to demonstrate gaps in how today's artificial intelligence systems process images. The finding suggests that machines perceive the trick differently from humans, highlighting limits in current computer vision models. Researchers and science outlets are discussing what this means for the reliability of AI vision systems.

AI ethics researcher Timnit Gebru is being praised for challenging an artificial intelligence industry that concentrates enormous power in a handful of companies while presenting its vision of the future as inevitable. Supporters say her work puts human agency back at the centre of technological development, arguing that the direction of technology remains a choice rather than a foregone conclusion, and that her critique resonates as AI firms grow more influential.

A widely shared optical illusion is being used to demonstrate a surprising gap in how artificial intelligence systems see, mirroring the way the human visual system fills in blind spots. The test shows AI vision models can miss what people perceive, highlighting differences between machine and biological perception and prompting discussion about the limits of current computer vision technology.
- 13US School Leaders Push Human-Centered Public EducationβΌReimagining Public Education: Leadership, Learning, and the Shift Toward Human-Centered Schools
AASA, The School Superintendents Association, has put forward a vision for reimagining public education centered on leadership, learning, and human-centered schools. The initiative calls on district leaders to move beyond traditional models and focus on student wellbeing and community engagement in how schools are run. The framework is being shared with superintendents across the United States as districts weigh post-pandemic changes in teaching and school culture.
- 14Cassowary casques found to glow under ultraviolet lightβMoment of Science: Cassowary headgear glows under UV light, study finds
A new study has found that the cassowary's headgear, or casque, glows under ultraviolet light, revealing fluorescent properties in the large flightless bird native to New Guinea and northern Australia. Researchers say the discovery adds to growing evidence that birds may perceive light beyond human vision, and it is attracting attention from science outlets and nature enthusiasts alike.
- 15Thunderbirds was a strikingly optimistic view of humanity, writer arguesβThunderbirds was far more than puppets on strings β it was a strikingly optimistic view of humanity
A Guardian essay argues that Thunderbirds, the classic British puppet series created by Gerry and Sylvia Anderson, deserves to be remembered as more than a technical curiosity about marionettes. The piece contends the show offered a strikingly optimistic vision of humanity, celebrating international cooperation, rescue and ingenuity in the face of disaster rather than cynicism or fear.
