A Billionaire-Backed Startup Wants to Grow ‘Organ Sacks’ to Replace Animal Testing
As the Trump administration phases out the use of animal experimentation across the federal government, a biotech startup has a bold idea for an alternative to animal testing: nonsentient “organ sacks.”
Bay Area-based R3 Bio has been quietly pitching the idea to investors and in industry publications as a way to replace lab animals without the ethical issues that come with living organisms. That’s because these structures would contain all of the typical organs—except a brain, rendering them unable to think or feel pain. The company’s long-term goal, cofounder Alice Gilman says, is to make human versions that could be used as a source of tissues and organs for people who need them.
For Immortal Dragons, a Singapore-based longevity fund that’s invested in R3, the idea of replacement is a core strategy for human longevity. “We think replacement is probably better than repair when it comes to treating diseases or regulating the aging process in the human body,” says CEO Boyang Wang. “If we can create a nonsentient, headless bodyoid for a human being, that will be a great source of organs.”
The depths of Neptune and Uranus may be ‘superionic’
The interiors of ice giant planets like Uranus and Neptune could be home to a previously unknown state of matter, according to new computational simulations by Carnegie’s Cong Liu and Ronald Cohen. Their work, published in Nature Communications, predicts that a quasi-one-dimensional superionic state of carbon hydride exists under the extreme pressures and temperatures found deep inside these outer solar system bodies.
More than 6,000 exoplanets have been discovered. As this number grows, astronomers, planetary scientists, and Earth scientists are crossing disciplinary boundaries—combining observation, experimentation, and theory—to define and probe the factors that help us understand the dynamic processes that shape them, including the generation of magnetic fields.
As such, interest has grown in understanding the processes that are occurring deep beneath the surfaces of planets and moons in our own solar system, which can inform our understanding of planetary dynamics, and even planetary habitability in more-distant neighborhoods.
Netta Engelhardt: Puzzles in the Black Hole Interior: Past, Present and Future (April 22, 2026)
In this Presidential Lecture, Netta Engelhardt will (metaphorically!) dive straight into the black hole interior to explain the origin of this puzzle and its significance in modern physics. The lecture will then turn to the recent revolution in physicists’ understanding of the black hole information paradox and the current state of the resolution. She will conclude with a discussion of where these new insights may lead, what questions remain outstanding and how this may all fit into the universe at large.

The Singular Mind: All Conscious Beings Are One
What if there is only one mind in the universe… and everything you call “yourself” is just a fragment of it? What if the sense that you are separate—from others, from the world, from everything—is not a truth… but an illusion? The physicist Erwin Schrödinger, one of the founding figures of quantum mechanics, proposed something that goes far beyond science: that consciousness is not divided. Not split between individuals. Not generated separately in billions of brains. But singular. One. The same awareness looking through countless perspectives. And if that is true, then the deepest question becomes unavoidable: are you truly an individual consciousness… or are you the universe itself, experiencing itself from one point of view?

A Mercury rover could explore the planet by sticking to the Terminator
The closest planet to our sun, Mercury, experiences extreme temperature variations. Since the planet has no atmosphere to speak of, it is in a constant cycle where one side is extremely hot and the other extremely cold. On the sun-facing side, temperatures reach a scorching 427°C (800°F), enough to melt tin and lead, and the surface is exposed to extremely lethal levels of radiation. On the night side, temperatures plunge)] to a chilling −173°C (−279.4°F), cold enough to freeze most liquids, including those used in battery manufacturing.
All of this makes exploring Mercury’s surface very challenging. On the one hand, a rover would be subject to interference from the sun’s radiation on the sun-facing side and would likely melt down. On the other hand, a solar-powered rover cannot operate on the night side, and a battery-powered vehicle would likely lose power quickly as its batteries die. But in the Terminator, the region between night and day on Mercury, temperatures are stable enough, and there is sufficient light for a solar-powered rover to study surface features and conduct science operations.
This is the proposal put forth by a research team from the Hawai’i Institute of Geophysics and Planetology (0HIGP) at the University of Hawai’i at Mānoa. The team included Mari Murillo, a Planetary Science Ph.D. Student at HIGP, and Paul G. Lucey, a prominent researcher with HIGP and Murillo’s Ph.D. advisor. The paper detailing their proposal was presented at the 2026 Lunar and Planetary Science Conference (2026 LPSC).
These AI-powered guide dogs don’t just lead, they talk
Guide dogs are powerful allies, leading the visually impaired safely to their destinations, but they can’t talk with their owners—until now. Using large language models, a team of researchers at Binghamton University, State University of New York has created a talking robot guide dog system that determines an ideal route and safely guides users to their destination, offering real-time feedback along the way.
The paper, “From Woofs to Words: Towards Intelligent Robotic Guide Dogs with Verbal Communication,” was presented at the 40th Annual AAAI Conference on Artificial Intelligence (AAAI 2026), held January 20–27 in Singapore. It is also available on the arXiv preprint server.
“For this work, we’re demonstrating an aspect of the robotic guide dog that is more advanced than biological guide dogs,” said Shiqi Zhang, an associate professor at the Thomas J. Watson College of Engineering and Applied Science’s School of Computing. “Real dogs can understand around 20 commands at best. But for robotic guide dogs, you can just put GPT-4 with voice commands. Then it has very strong language capabilities.”
