Physicists have simulated a black hole in a lab. Then it started glowing.
This allowed the team to realise that their black hole analogue may help explain so-called “Hawking radiation”, theorised to be emitted by black holes in nature.
Their analysis of the black hole in a bottle is presented in a paper published in the Physical Review Research journal.
You can’t discuss fulfillment robots without mentioning Amazon. Over the past decade, the retail juggernaut has become the 800-pound gorilla in the category, courtesy of several key acquisitions and seemingly endless resources. And while warehouse robotics and automation have been accelerated amid the pandemic and resulting employment crunch, Amazon Robotics has been driving these categories for years now.
This week at its annual Re: Mars conference in Las Vegas, the company celebrated a decade of its robotics division, which was effectively born with its acquisition of Kiva Systems. Over the course of its life, Amazon Robotics has deployed more than 520,000 robotic drive units, across its fulfillment and sort centers. From the outside, it’s been a tremendous success in the company’s push toward same-and next-day package delivery, and its driven the competition to look for their own third-party robotics solutions, bolstering startups like Locus, Fetch and Berkshire Grey.
Summary: The adult brain contains millions of “silent synapses”, or immature connections between neurons that remain inactive until they are required for learning new information and storing new memories.

MIT neuroscientists have discovered that the adult brain contains millions of “silent synapses” — immature connections between neurons that remain inactive until they’re recruited to help form new memories.
We then tested the new algorithms, called DQN with Proximal updates (or DQN Pro) and Rainbow Pro on a standard set of 55 Atari games. We can see from the graph of the results that the Pro agents overperform their counterparts; the basic DQN agent is able to obtain human-level performance after 120 million interactions with the environment (frames); and Rainbow Pro achieves a 40% relative improvement over the original Rainbow agent.
Further, to ensure that proximal updates do in fact result in smoother and slower parameter changes, we measure the norm differences between consecutive DQN solutions. We expect the magnitude of our updates to be smaller when using proximal updates. In the graphs below, we confirm this expectation on the four different Atari games tested.
Overall, our empirical and theoretical results support the claim that when optimizing for a new solution in deep RL, it is beneficial for the optimizer to gravitate toward the previous solution. More importantly, we see that simple improvements in deep-RL optimization can lead to significant positive gains in the agent’s performance. We take this as evidence that further exploration of optimization algorithms in deep RL would be fruitful.

The breakthrough could suggest a way to study ‘quantum gravity,’ the missing link between quantum physics and Einstein’s general relativity in the lab.
The treatment caused neurological changes, including a decrease in inflammation and an increase in functionality, according to the researchers.
A recent Tel Aviv University study found that pressure chamber therapy greatly improved social skills and the condition of the autistic brain. The research was carried out on autism animal models. The researchers discovered changes in the brain, including a decrease in neuroinflammation, which has been linked to autism. Furthermore, the social functioning of the animal models treated in the pressure chamber improved significantly. The success of the research has significant implications for the applicability and understanding of pressure chamber therapy as a treatment for autism.
Inbar Fischer, a Ph.D. student in Dr. Boaz Barak’s lab at Tel Aviv University’s Sagol School of Neuroscience and School of Psychological Sciences, led the team that made the discovery. The findings were recently published in the International Journal of Molecular Sciences.

The universe is going to end. But of all the possible ends of the universe vacuum decay would have to be the most thorough — because it could totally rewrite the laws of physics. Today I hope to help you understand exactly how terrified you should be.

Scientists may have found an answer to a unique issue people who can pee standing up face daily. After extensive research, scientists have found a urinal toilet design they say eliminates splashing and mess — you know, when you’re peeing and all of the sudden your pants have caught some strays, too.
Using modified MRI machines, physicists may have found quantum entanglement between the heart and brain If someone were to (theoretically) throw a wrench at your head, you might be able to catch it just in time to avoid a concussion. But how? Typically, for split-second reactions, we do not consciously decide to catch.
