Statement on the Re-election of Richard Stallman to the FSF Board

We at EFF are profoundly disappointed to hear of the re-election of Richard Stallman to a leadership position at the Free Software Foundation, after a series of serious accusations of misconduct led to his resignation as president and board member of the FSF in 2019. We are also disappointed that this was done despite no discernible steps taken by him to be accountable for, much less make amends for, his past actions or those who have been harmed by them. Finally, we are also disturbed by the secretive process of his re-election, and how it was belatedly conveyed to FSF’s staff…

Pubs that check Covid status may be allowed to drop social distancing

Exclusive: plan under consideration as Boris Johnson tells MPs landlords should set criteria for entry Coronavirus – latest updates See all our coronavirus coverage Pubs could be allowed to ditch social distancing rules and allow people to crowd together as long as they check customers’ Covid status on entry, the Guardian understands. Details of the proposed incentive emerged as Boris Johnson told MPs he believed landlords should be able to set the criteria for entering their establishments. Continue reading… Source: The Guardian: Pubs that check Covid status may be allowed to drop social distancing ———

Suez Canal container ship accident is a worst-case scenario for global trade

It’s estimated that 90% of the world’s trade is transported by sea. As consumers, we rarely give much thought to how the things we buy make their way across the planet and into our homes. That is, until an incident like the recent grounding of a huge container ship, the Ever Given, in the Suez Canal exposes the weaknesses in this global system. High winds have been blamed for the container ship blocking the narrow strait, which serves as a trade artery that connects the Mediterranean and the Red Sea. But with shipping so heavily reliant on such narrow channels,…

Adjuvants: the unsung heroes of vaccines

Gaston Ramon, a French vet, discovered vaccine adjuvants. Wellcome Collection/Wikimedia Commons, CC BY-SA Emerging from vague familiarity into the spotlight as the only route out of the pandemic, vaccines have become an everyday topic of conversation. Most of us now understand the principle of vaccination: our immune system is presented with a part of a pathogen and instructed to create a lasting immune response to it, safeguarding us against future infection. But few people know about vaccine ingredients that can be essential for inducing a potent immune response: adjuvants. Named from the Latin “adiuvare” meaning “to help”, adjuvants have been…

Petition EU to ban biometric mass surveillance practices

Civil society initiative for a ban on biometric mass surveillance practices We call on the European Commission to strictly regulate the use of biometric technologies in order to avoid undue interference with fundamental rights. In particular, we ask the Commission to prohibit, in law and in practice, indiscriminate or arbitrarily-targeted uses of biometrics which can lead to unlawful mass surveillance.

Dual-responsive biohybrid neutrobots for active target delivery

Swimming biohybrid microsized robots (e.g., bacteria- or sperm-driven microrobots) with self-propelling and navigating capabilities have become an exciting field of research, thanks to their controllable locomotion in hard-to-reach areas of the body for noninvasive drug delivery and treatment. However, current cell-based microrobots are susceptible to immune attack and clearance upon entering the body. Here, we report a neutrophil-based microrobot (“neutrobot”) that can actively deliver cargo to malignant glioma in vivo. The neutrobots are constructed through the phagocytosis of Escherichia coli membrane-enveloped, drug-loaded magnetic nanogels by natural neutrophils, where the E. coli membrane camouflaging enhances the efficiency of phagocytosis and also…

Reinforcement learning with artificial microswimmers

Artificial microswimmers that can replicate the complex behavior of active matter are often designed to mimic the self-propulsion of microscopic living organisms. However, compared with their living counterparts, artificial microswimmers have a limited ability to adapt to environmental signals or to retain a physical memory to yield optimized emergent behavior. Different from macroscopic living systems and robots, both microscopic living organisms and artificial microswimmers are subject to Brownian motion, which randomizes their position and propulsion direction. Here, we combine real-world artificial active particles with machine learning algorithms to explore their adaptive behavior in a noisy environment with reinforcement learning. We…
