Nanoreactor Mimics Living Cells To Supercharge Artificial Photosynthesis

A biomimetic nanoreactor combines cellular design principles to produce hydrogen peroxide efficiently under visible light.

Inside a hollow nanoscale structure, researchers have recreated two strategies that living cells use to control chemical reactions. The resulting CdS@polydopamine nanoreactor offers a synthetic way to reproduce some of the organization and efficiency found in biological systems.

The work was published in the Journal of the American Chemical Society. Can Li of the Dalian Institute of Chemical Physics (DICP), part of the Chinese Academy of Sciences (CAS), led the research with Jian Liu’s group at Inner Mongolia University.

The global biogeography of passerine songs

Although bird songs are classic models for understanding the evolution of vocal communication, their global diversity has long made the development of a unifying framework challenging. By analyzing the acoustic architecture of songs from more than 3,000 passerine species worldwide, we show that this acoustic space can be structured around eight elemental motifs. The differential use of these motifs is driven by a combination of species’ biological traits (social organization, morphology, and mating system) and the physics of sound propagation. In tropical rainforests, environmental filtering for transmission efficiency favors structurally simple motifs, such as flat whistles.

Brain waves once seen as noise could help build a biological model of reality

Your brain has something surprising in common with the ocean: waves. Electrical activity washes over the brain’s surface, creating what are called traveling brain waves, or neural traveling waves. These waves cause real differences in your behavior and attention and—again, like ocean waves—can have variable causes, from intrinsic activity to environmental inputs.

A new review article by Salk Institute neuroscientists synthesizes physiological and computational information about these neural traveling waves and draws a new conclusion: Neural traveling waves are a computational engine in the visual cortex. These waves allow the visual cortex (and likely other areas of the brain) to build representations of the external world, enabling our capacity to predict, reconstruct and perceive the world around us.

The piece was published in Neuron on July 21, 2026.

Twisted laser light distinguishes mirror-image molecules by their fragment counts

Many molecules exist in two mirror-image forms—like left and right hands—that look identical but can behave very differently, especially in biological systems and pharmaceuticals. Distinguishing between these enantiomers (also called chiral molecules) is a longstanding challenge in science and technology. A useful analogy is that of a screw and a nut: A right-handed screw fits only into a right-handed thread, while a left-handed one will not engage properly.

Researchers from Tata Institute of Fundamental Research, Indian Institute of Technology Bombay and Indian Institute of Technology Hyderabad illustrate how light itself can be engineered to behave like such a threaded probe, selectively interacting with molecules depending on their handedness.

The study, published in Science Advances, shows that light can be shaped not only to spin but also to twist as it travels. When such twisted light interacts with chiral molecules, the outcome depends sensitively on how the “twist” of the light matches the intrinsic handedness of the molecule.

Aspirin reverses diet-driven depression-like behavior in mice

Depression is among the most common psychiatric disorders, estimated to affect between 280 million and 332 million people worldwide. This disorder is characterized by persistent sadness and hopelessness, low energy, a loss of interest in everyday activities and sometimes changes in appetite or sleep.

Several factors can contribute to the onset of depression, including genetics, chronic stress, traumatic or challenging life events and biochemical imbalances in the brain. Recent studies suggest that people’s diets can also sometimes influence their mental health and may play a role in the emergence of depressive symptoms.

Some research findings suggest that the long-term consumption of foods rich in fat is linked to an increased risk of depression. The biological processes underpinning this relationship, however, have not yet been clearly elucidated.

Protein excess tips the balance of cellular health

For cells to function properly, they must produce the right amount of each protein. It is a delicate balance: both too little and too much can compromise essential cellular functions. A research team has now shown that even a modest excess of tubulin – the protein that assembles into microtubules, the cell’s internal scaffolding – is enough to disrupt tissue architecture and reduce cell viability. Published in Nature Communications, the study demonstrates that the quantity of a protein is just as important as its function.

Microtubules, built from tubulin, form the cell’s internal skeleton. They help cells maintain their shape, transport molecules, divide, and remain firmly attached to neighbouring cells. Rather than being rigid structures, microtubules are constantly assembled and disassembled to adapt to the cell’s changing needs. This dynamic behavior depends directly on the amount of tubulin available.

For more than forty years, biologists have known that cells possess a mechanism that slows tubulin production when its levels become too high. However, the biological purpose of this regulatory pathway remained unknown. To address this question, the team used three-dimensional spheroids. “These 3D cell culture models behave like tissues and reproduce cell-cell interactions much more faithfully than conventional two-dimensional cultures,” the author explains.

Charlie Stross: The World is Complicated. Elegant Narratives Explaining Everything Are Wrong!

Fifteen years ago, I interviewed Charlie Stross about a short story called “Lobsters.”

This spring, a thousand people queued outside Tencent’s Shenzhen headquarters to raise one.

June 2011, Singularity 1 on 1. Back then, “singularity” was a word most people filed under astrophysics, not #AI. Charlie’s 2001 story “Lobsters,” which grew into Accelerando, was one of the sharpest early maps of what happens when intelligence stops being exclusively biological. Uploaded minds. Post-scarcity economics. Legal personhood for software. An economy run by optimization processes no human fully follows.

He wrote it six years before the iPhone.

Now look at 2026. OpenClaw, the open source agent built by Austrian developer Peter Steinberger, now at OpenAI, became the fastest-growing project in GitHub history. In China, installing it is called 养龙虾, “raising lobsters,” after the red logo. Shenzhen, Wuxi and Changshu rushed out subsidy packages. Retirees, schoolkids and office workers lined up for help. A grey market of house-call technicians appeared within days.

Any connection to Charlie’s story? None. The logo is a claw pun on Claude.

Advancing NeuroAI through developmental alignment

Ayzenberg et al. describe how principles from child development can be used to improve the capacities and biological plausibility of AI models. These principles can be incorporated into every stage of the modeling process, from the architectures to the benchmarks.
