Eerie Video of Bizarre Sheep Phenomenon Has The World Running in Circles
To be a sheep is to blindly follow the crowd. But is a sheep’s sheepiness really enough to make an entire flock walk around in a circle non-stop for days on end?
That’s a mystery the internet has pondered for about a week now and solving it has proved more difficult than you’d expect.
On 17 November, a news outlet run by the Chinese state, called People’s Daily, shared an eerie video on Twitter of dozens of sheep in China’s Inner Mongolia Autonomous Region a strolling around in tight, almost perfect concentric circles.
Hackers modify popular OpenVPN Android app to include spyware
A threat actor associated with cyberespionage operations since at least 2017 has been luring victims with fake VPN software for Android that is a trojanized version of legitimate software SoftVPN and OpenVPN.
Researchers say that the campaign was “highly targeted” and aimed at stealing contact and call data, device location, as well as messages from multiple apps.
Inspired by Manta Ray Biomechanics: “Butterfly Bot” Is Fastest Swimming Soft Robot Ever
Researchers have developed an energy-efficient soft robot that can swim more than four times faster than previous swimming soft robots by taking inspiration from the biomechanics of the manta ray. Developed at North Carolina State University.
Founded in 1,887 and part of the University of North Carolina system, North Carolina State University (also referred to as NCSU, NC State, or just State) is a public land-grant research university in Raleigh, North Carolina. It forms one of the corners of the Research Triangle together with Duke University in Durham and The University of North Carolina at Chapel Hill.
Like a human? Artificial neural networks need to sleep to learn better
It’s time to go to bed for artificial neurons.
According to a recent study by the University of California, San Diego, neural networks can imitate the sleep patterns of the human brain in order to tackle catastrophic forgetting.
“The brain is very busy when we sleep, repeating what we have learned during the day,” said Maxim Bazhenov, Ph.D., professor of medicine and a sleep researcher at the University of California San Diego School of Medicine in the press release. “Sleep helps reorganize memories and presents them in the most efficient way.”
Sleep strengthens rational memory, the capacity to recall arbitrary or illogical associations between objects, people, or events, and guards against forgetting previous memories, according to research by Bazhenov and colleagues.
Artificial neural network: Here’s everything you need to know about black box of AI
They were created to imitate neural networks within the human brain.
Artificial neural networks (ANNs) mimic biological neural networks in the human brain. ANN consists of an input layer, a hidden layer, and an output layer.
Also called neural nets, ANNs are used daily in healthcare, social media when suggesting people you might know, and in marketing when recommending products to consumers.
Artificial neural networks (ANNs), also known as neural nets, are computing systems that are inspired by the way biological neural networks work in the human, or other animals, brain.

AI tailors artificial DNA for future drug development
With the help of an AI, researchers at Chalmers University of Technology, Sweden, have succeeded in designing synthetic DNA that controls the cells’ protein production. The technology can contribute to the development and production of vaccines, drugs for severe diseases, as well as alternative food proteins much faster and at significantly lower costs than today.
How genes are expressed is a process that is fundamental to the functionality of cells in all living organisms. Simply put, the genetic code in DNA is transcribed to the molecule messenger RNA (mRNA), which tells the cell’s factory which protein to produce and in which quantities.
Researchers have put a lot of effort into trying to control gene expression because, among other things, it can contribute to the development of protein-based drugs. A recent example is the mRNA vaccine against COVID-19, which instructed the body’s cells to produce the same protein found on the surface of the coronavirus.
San Francisco police consider letting robots use ‘deadly force’
The San Francisco Police Department is proposing a new policy that would give robots the license to kill, as reported earlier by Mission Local (via Engadget). The draft policy, which outlines how the SFPD can use military-style weapons, states robots can be “used as a deadly force option when risk of loss of life to members of the public or officers is imminent and outweighs any other force option.”
As reported by Mission Local, members of the city’s Board of Supervisors Rules Committee have been reviewing the new equipment policy for several weeks. The original version of the draft didn’t include any language surrounding robots’ use of deadly force until Aaron Peskin, the Dean of the city’s Board of Supervisors, initially added that “robots shall not be used as a Use of Force against any person.”
However, the SFPD returned the draft with a red line crossing out Peskin’s addition, replacing it with the line that gives robots the authority to kill suspects. According to Mission Local, Peskin eventually decided to accept the change because “there could be scenarios where deployment of lethal force was the only option.” San Francisco’s rules committee unanimously approved a version of the draft last week, which will face the Board of Supervisors on November 29th.
