New Video Shows Beverly Hills Cops Playing Beatles to Trigger Instagram Copyright Filter

Posted by in category: media & arts

In comments to City Council last year about APD’s intellectual property enforcement grant, I warned council that one thing I was concerned about was that APD might try to confiscate/remove activist videos by issuing takedown notices for copyrighted music playing in the background of the videos. Looks like I was right to be worried.


In at least three cases, Beverly Hills Cops have started playing music seemingly to prevent themselves from being filmed by an activist.

The Case (or Not) for Life in the Venusian Clouds

Posted by in category: alien life

The case (or not) for life in the clouds of Venus, re-evaluated 7 months after the initial claimed detection of phosphine in its atmosphere.


The possible detection of the biomarker of phosphine as reported by Greaves et al. in the Venusian atmosphere stirred much excitement in the astrobiology community. While many in the community are adamant that the environmental conditions in the Venusian atmosphere are too extreme for life to exist, others point to the claimed detection of a convincing biomarker, the conjecture that early Venus was doubtlessly habitable, and any Venusian life might have adapted by natural selection to the harsh conditions in the Venusian clouds after the surface became uninhabitable. Here, I first briefly characterize the environmental conditions in the lower Venusian atmosphere and outline what challenges a biosphere would face to thrive there, and how some of these obstacles for life could possibly have been overcome.

First collaborative robot to work with vehicles in motion

Posted by in categories: robotics/AI, transportation

The Ph.D. thesis by Daniel Teso-Fernández de Betoño of the UPV/EHU Faculty of Engineering in Vitoria-Gasteiz has resulted in a mobile, collaborative platform capable of performing tasks in motion at the Mercedes-Benz plant in the capital of Alava. The research opens up a new field for improving the ergonomics of these workstations and for the robot and human to collaborate by performing tasks together.

The idea of collaborative robotics with autonomous navigation to perform screwdriving tasks in motion emerged at the Mercedes-Benz plant in Vitoria-Gasteiz. To develop his Ph.D. thesis, Daniel Teso-Fernández de Betoño sought to investigate, develop and implement an adequate, efficient technology within the lines of work, and which would cooperate with the workers.

On the Mercedes-Benz final assembly lines, the vast majority of tasks require manual operations. It is also an area where everything is in motion, which means that not all types of people can opt to work in these spaces.

Solving ‘barren plateaus’ is the key to quantum machine learning

Posted by in categories: information science, mathematics, quantum physics, robotics/AI

Many machine learning algorithms on quantum computers suffer from the dreaded “barren plateau” of unsolvability, where they run into dead ends on optimization problems. This challenge had been relatively unstudied—until now. Rigorous theoretical work has established theorems that guarantee whether a given machine learning algorithm will work as it scales up on larger computers.

“The work solves a key problem of useability for . We rigorously proved the conditions under which certain architectures of variational quantum algorithms will or will not have barren plateaus as they are scaled up,” said Marco Cerezo, lead author on the paper published in Nature Communications today by a Los Alamos National Laboratory team. Cerezo is a post doc researching at Los Alamos. “With our theorems, you can guarantee that the architecture will be scalable to quantum computers with a large number of qubits.”

“Usually the approach has been to run an optimization and see if it works, and that was leading to fatigue among researchers in the field,” said Patrick Coles, a coauthor of the study. Establishing mathematical theorems and deriving first principles takes the guesswork out of developing algorithms.

WHO thinks it knows where COVID-19 originated

Posted by in categories: biotech/medical, food, government

The report said the wildlife farms were part of a project the Chinese government has been promoting for 20 years.

Daszak said: “They take exotic animals, like civets, porcupines, pangolins, raccoon dogs and bamboo rats, and they breed them in captivity,” NPR cited. He added that the project was a means to “alleviate rural populations out of poverty,”

These biodegradable face masks turn into flowers when you plant them

Posted by in categories: food, sustainability

What a beautiful idea.


A woman from the Netherlands has come up with an innovative alternative design for a face mask. Marianne de Groot-Pons, a graphic designer living and working in Utrecht, has created 100% biodegradable masks made out of rice paper and embedded with flower seeds. Once you’ve gotten enough wear out of it, you simply plant the mask and wait for the flowers to grow.

What a lovely take on an object which has become a daily essential in our lives.

Facebook’s upcoming AR wrist controllers will hijack your nerves

Posted by in categories: augmented reality, computing, cyborgs, ethics, mobile phones, space, virtual reality

All of which would be nice and handy, but clearly, privacy and ethics are going to be a big issue for people — particularly when a company like Facebook is behind it. Few people in the past would ever have lived a life so thoroughly examined, catalogued and analyzed by a third party. The opportunities for tailored advertising will be total, and so will the opportunities for bad-faith actors to abuse this treasure trove of minute detail about your life.

But this tech is coming down the barrel. It’s still a few years off, according to the FRL team. But as far as it is concerned, the technology and the experience are proven. They work, they’ll be awesome, and now it’s a matter of working out how to build them into a foolproof product for the mass market. So, why is FRL telling us about it now? Well, this could be the greatest leap in human-machine interaction since the touchscreen, and frankly Facebook doesn’t want to be seen to be making decisions about this kind of thing behind closed doors.

New research provides evidence that a single dose of psilocybin can boost brain connections

Posted by in category: neuroscience

Scientists in Denmark believe the psychedelic substance psilocybin might produce rapid and lasting antidepressant effects in part because it enhances neuroplasticity in the brain. Their new research, published in the International Journal of Molecular Sciences, has found evidence that psilocybin increases the number of neuronal connections in the prefrontal cortex and hippocampus of pig brains.

Psilocybin — the active component in so-called “magic” mushrooms — has been shown to have profound and long-lasting effects on personality and mood. But the mechanisms behind these effects remain unclear. Researchers at Copenhagen University were interested in whether changes in neuroplasticity in brain regions associated with emotional processing could help explain psilocybin’s antidepressant effects.

“Both post-mortem human brain and in vivo studies in depressed individuals have shown a loss of synapses through the down-regulation of synaptic proteins and genes,” the authors of the study wrote. “Hence, upregulation of presynaptic proteins and an increase in synaptic density may be associated with the potential antidepressive effects of psychedelics.”

Study shows stronger brain activity after writing on paper than on tablet or smartphone

Posted by in categories: mobile phones, neuroscience

A study of Japanese university students and recent graduates has revealed that writing on physical paper can lead to more brain activity when remembering the information an hour later. Researchers say that the complex, spatial and tactile information associated with writing by hand on physical paper is likely what leads to improved memory.

“Actually, paper is more advanced and useful compared to electronic documents because paper contains more one-of-a-kind information for stronger memory recall,” said Professor Kuniyoshi L. Sakai, a neuroscientist at the University of Tokyo and corresponding author of the research recently published in Frontiers in Behavioral Neuroscience. The research was completed with collaborators from the NTT Data Institute of Management Consulting.
