A brain-computer interface that works with—not against—the brain
It might soon be “game over” for the video game controller. Yale researchers have developed a new kind of brain-computer interface (BCI) that lets humans play video games directly with their brains. Using real-time fMRI (functional MRI), they confirmed that the technology could help humans control a computer with their brain activity in a highly efficient way. The study appears in the journal Nature Neuroscience.
A BCI is technology that allows a human to control a computer with brain activity. Historically, they have not been effective. BCIs built using real-time neurofeedback from fMRI—a type of MRI scan showing which areas of the brain are most active over time—require up to 10 long training sessions per person, and even then the learning effects are modest. About a third of users never gain control, regardless of how many hours they practice.
Space Plants Could Be Future Pharmacies for Astronauts
Scientists have successfully tested a non-destructive method to harvest life-saving medicines from plants under simulated space conditions, enabling on-demand drug production for long-duration missions.

How can plants help produce pharmaceuticals for future astronauts? This is what a recent study published in npj Science of Plants hopes to address as a team of scientists from the University of California San Diego (UCSD) investigated using plants to produce drugs for astronauts to treat a variety of ailments. This study has the potential to help scientists, mission planners, and astronauts develop new methods for addressing medical concerns on long-term space missions.
For the study, the researchers examined how cowpea mosaic virus (CPMV) could be produced under space-like conditions, including a vacuum environment, microgravity, using a centrifuge, the latter of which is commonly used in space for science experiments. CPMV is a plant virus-based compound that has been found to treat cancer while also possessing immunotherapy characteristics. The primary motivation behind the study was to address how to provide medical treatments to astronauts on long-term space missions without relying on Earth supplies. In the end, the researchers found that CPMV could successfully be extracted without harming the plants.
The study notes, “The combination of process-level and host-level optimization facilitates sustainable CPMV production under the constrained conditions of long-duration space missions while also offering practical advantages for terrestrial biomanufacturing.”
Peak Protocol: Mountain Longevity Retreat
Science-first longevity retreat in Colorado.
Hey friends, we’re running a longevity retreat in the CO mountains this August!
Peak Protocol is a 4-day science-first retreat at SageStone Adventure Lodge in Granite, CO (August 6–9).
The idea is to bring together people who want to get serious about their health, put them in a gorgeous venue with longevity doctors and scientists, and give everyone a personalized longevity plan to leave with.

Why this $10 spectrometer chip could bring real-time chemical sensing to wearables
Researchers from the University of Cambridge and GlitterinTech, a startup founded by the same research group, have unveiled a fundamentally new type of optical spectrometer that delivers laboratory-grade precision in a device small enough to be embedded in portable and wearable technologies. By rethinking how spectra are measured and processed, the team has demonstrated a spectrometer costing only around $10, operating at a centimeter scale, and capable of applications ranging from industrial quality control to real-time health care monitoring.
Optical spectrometers underpin countless technologies, from chemical analysis and manufacturing to environmental sensing and medicine. Yet shrinking these instruments has historically involved painful trade-offs: Miniaturized devices typically sacrifice bandwidth, resolution or accuracy, limiting them to rough identification rather than true metrological measurements. The newly reported convolutional spectrometer overcomes these barriers by introducing a conceptually elegant operating principle grounded in the convolution theorem, offering unprecedented performance metrics compared with existing dispersive, Fourier-transform and reconstructive spectrometers.
Satellites reveal cities’ ‘urban pulse,’ tracking neighborhood growth in near real time
For over a century, doctors have used electrocardiograms (EKGs) to render the invisible electrical activity of the human heart visible, using the pulse to diagnose disease before it becomes fatal. Now, scientists have invented a way to do the exact same thing for the places where most of humanity lives: cities.
In a recent study published in the Proceedings of the National Academy of Sciences, researchers introduced the concept of the “Urban Pulse.” By using dense, high-frequency satellite imagery, the team successfully tracked the dynamic, real-time metabolic activity of urban environments, effectively measuring the heartbeat of a city.
Zhe Zhu, director of the Global Environmental Remote Sensing (GERS) Laboratory and associate professor of natural resources and the environment in the College of Agriculture, Health and Natural Resources (CAHNR), was the first author. He worked in close collaboration with senior author Karen C. Seto, the Frederick C. Hixon Professor of Geography and Urbanization Science at the Yale School of the Environment, alongside Michail Fragkias of Boise State University and a multi-institutional team of researchers.
Chemists unlock first total synthesis of rare plant alkaloid tied to anticancer activity
Plants are undeniably one of nature’s most promising sources of new medicines, with monoterpenoid indole alkaloids (MIAs) being a great example. Some intricate compounds are built from multiple-linked chemical units that form highly complex three-dimensional structures. Because of their size and shape, scientists believe such oligomeric MIAs may be able to interfere with specific protein–protein interactions inside cells—a biological target that conventional small-molecule drugs often struggle to reach.
This unusual capability could make MIAs uniquely suited to combat various diseases. Such is the case for bisleuconothine A, an MIA isolated from plant bark in 2010 that has shown strong activity against breast cancer and lung cancer.
Despite their therapeutic potential, these compounds are extremely difficult to produce synthetically in the laboratory. Their structures contain multiple interconnected rings and several precisely arranged stereocenters, meaning their atoms must be assembled in the correct three-dimensional orientation to preserve their biological activity. Because of this, drug development research involving oligomeric MIAs remains limited.
The Universe Is About to Wake Up
Ray Kurzweil’s Six Epochs of Intelligence maps the entire history of the universe as a story of accelerating information processing, from subatomic particles to a future merger of human and artificial intelligence.
Each epoch operates on a dramatically compressed timescale compared to the one before, driven by what Kurzweil calls the Law of Accelerating Returns.
We trace the journey from atoms forming after the Big Bang, through the emergence of DNA and the Cambrian Explosion, to the rise of brains, technology, and what Kurzweil predicts comes next.
By 2029, he believes AI will pass the strong Turing test, opening the door to brain-computer interfaces that link our neocortices directly to the cloud.
The final epoch envisions intelligence spreading throughout the cosmos, though critics like Michael Shermer argue this collides with the laws of physics.
