Beyond our own Milky Way galaxy, there are physical limits on our access to the Universe. In this new video from PBS Space Time, we explore the absolute limit of our future view of the Universe, and of the Universe’s ability to influence us.

We humans have always been explorers. The great civilisations that have arisen across the world are owed to our restless ancestors. These days, there’s not much of Earth left to explore. But if we look up, there’s a whole Universe out there waiting for us. Future generations may one day explore the cosmos and could even settle entire other galaxies.

However, there is a fundamental limit to how much of the Universe we can expand into. So, just how big could humanity get? Matt O’Dowd, astrophysicist and host of PBS Space Time, looks at the obstacles that our descendants could face in the very distant future.

This work rests on our non-viral tissue nanotransfection (TNT) platform to deliver MyoD (TNTMyoD) to injured tissue in vivo. TNTMyoD was performed on skin and successfully induced expression of myogenic factors. TNTMyoD was then used as a therapy 7 days following volumetric muscle loss (VML) of rat tibialis anterior and rescued muscle function. TNTMyoD is promising as VML intervention.

Our civilization has leveraged humanism, science, technology, and a can-do attitude to make our world radically better than it ever has been before. Yet unimaginable tragedies still happen on a continuous basis. We will keep seeking solutions, improving the world, and making progress. Data support the idea that we are on the way. I urge us all to not lose faith in the power of progress. It is vital for the future of every living creature that we keep using science to change the world for the better.

From the article: “It is wrong to think that these three statements contradict each other. We need to see that they are all true to see that a better world is possible.”


The world is much better. The world can be much better. All three statements are true at the same time.

Discussions about the state of the world too often focus on the first statement: The news highlights what is going wrong, rarely mentioning any positive development.

A pushback on this narrative takes it to the other extreme, which is equally damaging. Solely communicating the progress that the world has achieved becomes unhelpful, or even repugnant, when it glosses over the problems that are real today.

In his book “A Brief History of AI,” Michael Wooldridge, a professor of computer science at the University of Oxford and an AI researcher, explains that AI is not about creating life, but rather about creating machines that can perform tasks requiring intelligence.

Wooldridge discusses the two approaches to AI: symbolic AI and machine learning. Symbolic AI involves coding human knowledge into machines, while machine learning allows machines to learn from examples to perform specific tasks. Progress in AI stalled in the 1970s due to a lack of data and computational power, but recent advancements in technology have led to significant progress. AI can perform narrow tasks better than humans, but the grand dream of AI is achieving artificial general intelligence (AGI), which means creating machines with the same intellectual capabilities as humans. One challenge for AI is giving machines social skills, such as cooperation, coordination, and negotiation.

The path to conscious machines is slow and complex, and the mystery of human consciousness and self-awareness remains unsolved. The limits of computing are only bounded by imagination.

Sony has announced that it intends to integrate its Aitrios edge computing (on-chip) AI platform into future iterations of the Rasberry Pi.

The highly popular Rasberry Pi will soon get artificial intelligence (AI) functions, according to an announcement from Sony. In what it has called a “strategic investment,” Sony decided to bring its AI technology to a broader market.

This announcement comes hot off the heels of other news that Raspberry Pi Limited, the UK-based company and creators of the Raspberry Pi, secured an undisclosed investment from Sony Semiconductor Solutions, a subsidiary of Sony Corporation.

Scientists have identified a new circuit element known as a meminductor. A circuit element is an electrical component used to help direct and control the flow of electricity through an electrical circuit. The classical three are known as the resistor, capacitor and inductor. Two additional circuit elements, the memristor and the memcapacitor, were only discovered in the past 15 years.
