How can we make the space sector more sustainable?

When talking about space, one might think about the stars one sees at night or a good sci-fi film. But space is also crowded with satellites, spacecrafts and astronauts, whose missions can last anywhere from several days to months. Meanwhile, 8,216 unmanned satellites revolve around Earth’s orbits to improve our daily lives. Communication satellites contribute to enhancing Internet access in regions deprived of infrastructure (so-called “white areas”); meteorology satellites have become essential for weather forecasts, while navigation satellites (including GPS) are crucial for current and future transportation needs such as automatic driving vehicles.

Technological advances in the sector have unlocked many new business opportunities. The industry can now launch constellations of thousand satellites to reach corners of the earth as it had never before (e.g., Starlink), while new markets such as space mining and space tourism are steadily growing. National champions (including the United States and France) have also framed the space sector as a top economic priority. It is thought the technological benefits accrued by companies such as SpaceX, Blue Origin or OneWeb, launched by billionaires such as Elon Musk, will also be able to trickle down to non-space sectors such as the energy or freight industries.

Researchers Have Developed an Incredible New Method of Producing Realistic Holograms

Posted by in categories: encryption, holograms

Researchers have developed a new method for creating realistic 3D holographic projections that are three orders of magnitude better than the current state-of-the-art technology. Previous attempts to improve the resolution of holograms have run into three basic roadblocks. However, this new ultrahigh-density method shows that two of those have now been solved, dramatically improving the overall quality, resolution, and appearance of holographic projections.

“Our new method overcomes two long-existing bottlenecks in current digital holographic techniques — low axial resolution and high interplane crosstalk — that prevent fine depth control of the hologram and thus limit the quality of the 3D display,” said Lei Gong, who led a research team from the University of Science and Technology of China. “Our approach could also improve holography-based optical encryption by allowing more data to be encrypted in the hologram.”

Limitations of Current Methods for Generating Holograms.

Generative AI will change the world—but won’t put creative jobs at risk

Posted by in categories: employment, robotics/AI

By allowing creators to explore more directions more quickly, generative AI will help them rather than displace them.

Scientists were able to enhance long-term memory storage in mice. Here’s how

Posted by in categories: neuroscience, virtual reality

Researchers in New York developed a virtual reality maze for mice in an attempt to demystify a question that’s been plaguing neuroscientists for decades: How are long-term memories stored?

What they found surprised them. After forming in the hippocampus, a curved structure that lies deep within the brain, the mice’s memories were actually rooted through what’s called the anterior thalamus, an area of the brain that scientists haven’t typically associated with memory processing at all.

“The thalamus being a clear winner here was very interesting for us, and unexpected,” said Priya Rajasethupathy, an associate professor at Rockefeller University and one of the coauthors of a peer-reviewed study published in the journal Cell this week. The thalamus “has often been thought of as a sensory relay, not very cognitive, not very important in memory.”

New AI model can “cut out” any object within an image—and Meta is sharing the code

Posted by in category: robotics/AI

On Wednesday, Meta announced an AI model called the Segment Anything Model (SAM) that can identify individual objects in images and videos, even those not encountered during training, reports Reuters.

According to a blog post from Meta, SAM is an image segmentation model that can respond to text prompts or user clicks to isolate specific objects within an image. Image segmentation is a process in computer vision that involves dividing an image into multiple segments or regions, each representing a specific object or area of interest.

Post: What Will Transformers Transform?

Posted by in category: futurism

Generative Pre-trained Transformer models (GPTs) are now all the rage and have inspired op-eds being written by everyone from Henry Kissinger (WSJ) to Noam Chomsky (NYTimes) in just the last month. That sure is some hype level.

Way back in the early history of GPTs, January 1st this year, I wrote briefly about them and said:

Italy became the first Western country to ban ChatGPT. Here’s what other countries are doing

Posted by in categories: food, robotics/AI

It seems some countries in Europe might ban ChatGPT due to privacy reasons.


Italy isn’t the only country reckoning with the rapid pace of AI progression and its implications for society. Other governments are coming up with their own rules for AI, which, whether or not they mention generative AI, will undoubtedly touch on it. Generative AI refers to a set of AI technologies that generate new content based on prompts from users. It is more advanced than previous iterations of AI, thanks in no small part to new large language models, which are trained on vast quantities of data.

There have long been calls for AI to face regulation. But the pace at which the technology has progressed is such that it is proving difficult for governments to keep up. Computers can now create realistic art, write entire essays, or even generate lines of code, in a matter of seconds.

Ex-Theranos executive headed to prison after losing appeal

Posted by in categories: biotech/medical, law enforcement

Anyone wonder why he might end up serving a longer sentence than Elizabeth Holmes?


Former Theranos executive Ramesh “Sunny” Balwani will be heading to prison later this month after an appeals court rejected his bid to remain free while he contests his conviction for carrying out a blood-testing hoax with his former boss and lover, Elizabeth Holmes.
