NeuroXess, a Chinese startup, has made two major breakthroughs in brain-computer interface (BCI) technology, coming to the aid of a brain-damaged patient. The first was its ability to decode thoughts to speech in real time, and the other was remotely controlling a robot arm using thoughts alone.

Testing of the startup’s new BCI also enabled the user to talk to an artificial intelligence (AI) model and operate a digital avatar. These tests are result of an experiment undertaken in August 2024 at Huashan Hospital, where neurosurgeons implanted a 256-channel, high-throughput flexible BCI device into the patient’s brain.

A computational account of how schemas are learned through experience is lacking. In this Perspective, Bein and Niv synthesize schema theory and reinforcement learning research to derive computational principles that might govern schema learning and then propose their mediation via dimensionality reduction in the medial prefrontal cortex.

Summary: While humans share over 95% of their genome with chimpanzees, our brains are far more complex due to differences in gene expression. Research shows that human brain cells, particularly glial cells, exhibit higher levels of upregulated genes, enhancing neural plasticity and development.

Oligodendrocytes, a glial cell type, play a key role by insulating neurons for faster and more efficient signaling. This study underscores that the evolution of human intelligence likely involved coordinated changes across all brain cell types, not just neurons.

A recent study found that human brains process emotional expressions from humans and dogs similarly, with empathy enhancing attention to emotional cues. Aggressive faces elicited stronger neural responses, highlighting our sensitivity to emotionally significant stimuli across species.

An ancient brain circuit, which enables the eyes to reflexively rotate up as the body tilts down, tunes itself early in life as an animal develops, a new study finds.

Led by researchers at NYU Grossman School of Medicine, the study revolves around how vertebrates, which include humans and animals spanning evolution from primitive fish to mammals, stabilize their gaze as they move. To do so, they use a brain circuit that turns any shifts in orientation sensed by the balance (vestibular) system in their ears into an instant counter-movement by their eyes.

The research is published in the journal Science.

As computer chips continue to get smaller and more complex, the ultrathin metallic wires that carry electrical signals within these chips have become a weak link. Standard metal wires get worse at conducting electricity as they get thinner, ultimately limiting the size, efficiency, and performance of nanoscale electronics.

In a paper published in Science, Stanford researchers show that niobium phosphide can conduct electricity better than copper in films that are only a few atoms thick. Moreover, these films can be created and deposited at sufficiently low temperatures to be compatible with modern computer chip fabrication. Their work could help make future electronics more powerful and more energy efficient.

“We are breaking a fundamental bottleneck of traditional materials like copper,” said Asir Intisar Khan, who received his doctorate from Stanford and is now a visiting postdoctoral scholar and first author on the paper.

Sarah Cohen and two others will pioneer a method to view these molecular structures and their interactions in live stem cells.

In this interview, I sit down with Simon Critchley, Hans Jonas Professor of Philosophy at The New School for Social Research in New York, to explore his provocative new book, On Mysticism. Drawing on medieval Christian figures like Julian of Norwich and Marguerite Porete, Critchley argues that ecstatic experience, intense love, and a willingness to be “outside oneself” can offer a counterbalance to the narrowly rational outlook dominant in modern philosophy. Throughout our conversation, he probes the boundaries of faith and reason, discuss the possibility of maintaining mysticism alongside science, and question the role of philosophy itself in shaping our cultural consciousness. What follows is only a short, edited extract from Critchley’s call for more openness, both in our thinking and our collective search for meaning. Link to the full interview.
