Autonomous medical AI outperforms doctors in simulated EHR cases
MIRA, an autonomous AI agent tested in a sandboxed electronic health record, diagnosed 574 real emergency department cases with 88.9% accuracy and outperformed physicians in a matched 311-case comparison. The system ordered tests, generated medication plans, and made admission decisions in simulation, but the authors stress that prospective validation, governance, and physician oversight are still essential.
Light-controlled microgripper bridges the gap between precision and force
For some time, researchers have used optical tweezers to manipulate tiny objects with incredible precision, using carefully controlled beams of laser light. So far, however, this technique has always come with strict limits on how much force it can exert.
Through new research published in Nature, a team led by Dong Wu at Anhui University, China, has unveiled an improved design: a miniature mechanical gripper controlled by light signals through an optical fiber.
Combining the precision of light-based tools with the gripping strength of mechanical devices, the device could make it far easier for researchers to manipulate and assemble objects at the microscale.
Pan-cancer neurotransmitter receptor alterations define neuroregulatory subtypes with prognostic significance
Luo et al. characterize a comprehensive molecular portrait of neurotransmitter receptor genes across 33 cancer types using multidimensional omics data from The Cancer Genome Atlas and other independent cohorts. They identify clinically relevant neuroregulatory subtypes with distinct molecular features, advancing the emerging field of cancer neuroscience.
Tracy R. Atkins on Aeternum Ray: Don’t Wait For The Singularity
“Don’t Wait For The Singularity.”
That was Tracy R. Atkins’ message when I sat down with him 14 years ago, and it lands harder now than it did then.
While almost every story about #ArtificialIntelligence was busy imagining the apocalypse, Tracy wrote a novel that flatly refused to. Aeternum Ray is unapologetically utopian: a series of letters from a 240-year-old father to his newborn son, looking back across centuries of love, loss, and a world watched over by an AI named Ray.
In our conversation, we get into what the #Singularity actually means to him, why he chose to write utopia when dystopia sells, whether humanity’s future is digital or whether biology still matters, and the uncomfortable question of whether we even survive the road to get there.
Fourteen years on, the technology has caught up to much of what we talked about. The harder question is whether our reasons for building it have, and that is the part I keep coming back to.
So is openly imagining a good future naive, or is it the most radical thing a #futurist can do? Watch the interview and decide for yourself.
Red Mars to Green — Giving the Planet a Touch of Terraforming
GOLDEN, Colorado – Scientists are engaged in research with an eye toward transforming the cold climes of Mars into a far more humane place for Earthlings in the future.
One notion proposed is dispersion of an aerosol meant to motivate the warming of Mars’s atmosphere. The idea is projected to be a first step toward terraforming the Red Planet.
Emerging recently as a new field of study is “applied astrobiology” – to appraise what would be needed to create sustainable habitats and biospheres beyond Earth.

SpaceX may have just dropped its biggest hint yet about what comes after Starship Flight 13. Indeed, FINALLY! Starship’s Next Giant Leap may be here as the new filings point toward an Orbital Return Demo that could mark the next major milestone on the road to full reusability. With that work continues at Starbase on Pads 1 and 2, the Gigabay, and future launch infrastructure. Elsewhere this week, we cover Falcon 9 launches carrying BlueBird satellites, Starlink, and another classified NRO mission, Cargo Dragon’s return from the International Space Station, Astrobotic’s Griffin lunar lander preparing for launch, Ariane 6’s impressive upgraded debut with its heaviest payload yet, and the dramatic demolition of historic structures at Space Launch Complex 6.

The goal is to have at least one Flyover each week. However, Flyovers are dependent on two things.
1. The amount of support that viewers and Starship lovers provide.
2. Weather.
Flyover costs include pilot fees, plane rental fees, fuel and more. So, we genuinely appreciate you for not only joining us for these reviews, a perk of being a tiered team member, but also for your generosity!
The RGV Aerial Team greatly appreciate and feel thrilled to have such a supportive space community! THANK YOU FOR YOUR SUPPORT!
AI-designed universal vaccine clears first human trial, targets future coronavirus threats with needle-free delivery
The first human clinical trial of a universal Sarbeco coronavirus vaccine, developed by the University of Cambridge and spin-out DIOSynVax (DVX) Ltd, has shown that the vaccine is safe and has no significant side effects.
The trial, involving 39 healthy volunteers, tested a vaccine designed to provide protection against multiple Sarbeco coronaviruses—the large group of viruses that occur in nature including SARS-CoV-2, which caused the COVID pandemic.
The vaccine triggered immune responses in the volunteers not only to SARS-CoV-2 and SARS, but to related bat viruses that could potentially jump from animals to humans and cause future pandemics.
