Using less power than a lightbulb. A team of engineers at the University of Illinois Chicago (UIC) has developed a relatively low-cost “artificial leaf” that can capture carbon dioxide at rates 100 times faster than existing systems, bringing us one step closer to the goal of engineering the process of photosynthesis by which plants convert sunlight, water, and carbon dioxide into energy.

Nuclear waste can be very harmful to humans and the ecosystem. Watch how it’s handled in our video.

Nuclear power could be essential to weaning the world off fossil fuels.

Nuclear power is a powerful form of energy that allows us to produce clean electricity. However, the waste it produces is difficult to tackle and is often the reason nuclear power has not become as popular as perhaps it should be. It is estimated that there are currently around 370,000 tonnes of spent nuclear fuel in temporary storage around the world, according to the International Atomic Energy Agency.

The company sold roughly one million cars in 2021.

The electric vehicle manufacturer announced yesterday that it made $5.5 billion in profits last year after selling nearly one million cars. That’s six times more than it did in 2020. But even those numbers weren’t enough to reassure investors that Tesla’s future success is a sure thing.

“This is not ‘SpaceX did something bad’—it’s perfectly standard practice to abandon stuff in deep orbit,” writes McDowell. “This is ‘none of the space agencies care about leaving stuff out beyond the Moon’.”

However, with the age of commercial space industry there’s going to be a lot more junk like this. Something needs to be done. “It’s time for the world to get more serious about regulating and cataloging deep space activity,” writes McDowell. ## Why we need to launch rockets and satellites.

There seems to be a swell of doubt around whether the carbon footprints of rocket launches can be justified in this age of rampant climate change. Attaching the term “space junk” and Elon Musk’s name instantly make it a big and negative story.

The talk about metaverse really went ballistic after Facebook changed its corporate name to Meta and CEO Mark Zuckerberg’s keynote at the Facebook Connect event touted the metaverse as the social networking future. But most of the talk is not really about the true metaverse as envisioned in science fiction and first described in in Neal Stephenson’s 1992 cyberpunk science fiction novel Snow Crash. A true metaverse needs to be an interconnected “Internet” of virtual spaces that are open to many different companies, not a walled garden. It will take an open platform offering access to a shared virtual space to create the true metaverse. And it will also require a level of standardization and interoperability that doesn’t exist today.

In Snow Crash, the Metaverse was a phrase coined by as a successor to the Internet. It was a vision of how a virtual-reality-based Internet might evolve and was heavily influenced by early video games. This version of the metaverse resembles a persistent massive multiplayer online game (MMO). Players would have user-controlled avatars, and there were a social hierarchy, but there was pervasive access and a global scale.

The closest we came to open 3D interoperability was VRML (Virtual Reality Markup Language) back in the 1990s. The HTML approach to creating a metaverse using the VRML standard attempted to create a virtual 3D markup language that could be used to create and link 3D spaces together into one that you could access through a VRML browser. It failed.

Developed in Spain, the Arca system integrates solar panels, power electronics, and energy storage. Arca Lite has a rated power of 490 Wp, and Arca Plus of 980 Wp.

From pv magazine Latam

The Spanish companies Solartia and IED — experts in energy and electronics, respectively — have launched Arca, an autonomous solar power generator described as a robust and low-maintenance system that aims to alleviate energy poverty.

Academics say the material could be used to create unclonable physical components suitable for supporting digital security.

There is nothing inevitable about aging, or about its rate. Californian bristlecone pines are believed to live for 5,000 years, and there are long-lived mammalian creatures as well. Some marine creatures do not display any signs of aging at all, including hydra, jellyfish, planarian worms, and coral. Certain human cells have immortal characteristics too. When a woman gives birth, she produces a baby which is “new”. Her “germline” (reproduction-related) cells produce a child with no signs of age.

These and many other considerations combine with the unreasonable effectiveness of modern AI to lead some people to believe that significant advances in longevity are imminent. These advances probably cannot happen without the active participation of the wider pharmaceutical industry, and the acceptance by policy makers and regulators that aging is a disease, not just an unfortunate and inevitable component of the human condition. There is still considerable reluctance among major pharmaceutical companies to contemplate specific anti-aging therapeutic developments. But there are encouraging signs of this reluctance being challenged, especially at Novartis and AstraZeneca.

Beyond the pharma giants, Mellon reckons there are 255 companies which claim to be specifically targeting aging, of which 35 are listed on stock markets. But he thinks that only a minority of them are genuinely working to tackle aging, as opposed to one of the diseases it causes, like cancer, dementia, or heart disease. He likens the state of the longevity industry today to the internet industry of 20 years ago, when it was still in its dial-up phase, and downloading information (or, heaven forbid, images) was like sucking jelly through a straw. And although longevity will have such a massive impact on all of us that you might expect progress to be expedited, Mellon points out that the internet did not have to go through lengthy and expensive FDA trials at every step.

Autophagy is often likened to the trash management system of the cell. And just as municipal waste services involve collection, transportation and ultimately disposal, so too must the cell’s autophagy system follow a coordinated, multistep process. It first requires cellular refuse to be bagged up inside sack-like structures known as phagophores. These then mature into cargo containers called autophagosomes, which fuse with degradation hubs called lysosomes. Only then do waste products get broken down.

Any part of that cell-cleaning process could go wrong, and they often do as cells age. But if researchers do not fully understand what aspects of autophagy are defective in any particular disease, drugs that modulate the wrong parts of the pathway could do more harm than good. A therapy could, for instance, help the cell to package more trash. “But if your trash compactor isn’t working properly, you’re just going to end up with a room full of trash bags,” says Tim Sargeant, who studies autophagy at the South Australian Health and Medical Research Institute in Adelaide. “That’s one of the dangers here.”

As a result, although some anti-ageing researchers and companies have gone all-in on targeting autophagy, others are more circumspect — especially given the lack of solid evidence in people or even mouse models for many of the proposed interventions.
