“A majority of the country now knows that he’s the old man behind the curtain and not the wizard,” he said. “He still has control over Maga and Republicans in Congress but he doesn’t have the persuasive capacity any longer to keep his hold on the broad majority of the country.
“This is a sign of his weakness and that he’s not as strong as he believes he is. It’s one of the reasons why he’s looking for these avenues to re-establish his strength and power and have there be a perception that people are bending the knee.
“Every time he tries to do this, it fails and he grows more distant to the American people. That has to give us hope we have the tools in the coming months to start winning elections and building a more successful pro-democracy movement that can contain the damage that Trump and Maga are doing to the country in the coming years.”

Asynchronous Collective Tree Exploration: a Distributed Algorithm, and a new Lower Bound
We study the problem of collective tree exploration in which a team of $k$ mobile agents must collectively visit all nodes of an unknown tree in as few moves as possible. The agents all start from the root and discover adjacent edges as they progress in the tree. Communication is distributed in the sense that agents share information by reading and writing on whiteboards located at all nodes. Movements are asynchronous, in the sense that the speeds of all agents are controlled by an adversary a…

Long-term independent use of an intracortical brain-computer interface for speech and cursor control https://www.biorxiv.org/content/10.1101/2025.06.26.661591v1
I just checked: at least one of the congenitally blind users of The vOICe has been using The vOICe for over…

Long-term independent use of an intracortical brain-computer interface for speech and cursor control
Brain-computer interfaces (BCIs) can provide naturalistic communication and digital access to people with severe paralysis by decoding neural activity associated with attempted speech and movement. Recent work has demonstrated highly accurate intracortical BCIs for speech and cursor control, but two critical capabilities needed for practical viability were unmet: independent at-home operation without researcher assistance, and reliable long-term performance supporting accurate speech and cursor…

An Effective Equivalence Model of Analyzing PLS of Multiple Eavesdroppers Facing Low-altitude Communication Systems
In low-altitude wireless communications, the increased complexity of wireless channels and the uncertainty of eavesdroppers (Eves)--caused by diverse altitudes, speeds, and obstacles--pose significant challenges to physical layer security (PLS) technologies based on fixed-position antennas (FPAs), particularly in terms of beamforming capabilities and spatial efficiency. In contrast, movable antennas (MAs) offer a flexible solution by enabling channel reconstruction through antenna movement, eff…

Alignment Phase Transition in Socially Driven Motion
Collective human movement is a hallmark of complex systems, exhibiting emergent order across diverse settings, from pedestrian flows to biological collectives. In high-speed scenarios, alignment interactions ensure efficient flow and navigation. In contrast, alignment in low-speed, socially engaged contexts emerges not from locomotion goals but from interpersonal interaction. Using high-resolution spatial and orientation data from preschool classrooms, we uncover a sharp, distance-dependent tra…
