According to the current dominant theory, if there are other universes out there, they’re not likely to have life. But now an international team of researchers has demonstrated that the Multiverse is more hospitable than we thought.

The Multiverse hypothesis — wherein our observable Universe is just one of many universes — is a proposed explanation for the not-large-enough amount of dark energy in the empty space in our Universe.

We don’t really know what dark energy is — it’s the name we give to the force that drives the expansion of our Universe, which, contrary to pretty much everything else we observe, accelerates over time instead of slowing down.

Superconductors are among the most bizarre and exciting materials yet discovered. Counterintuitive quantum-mechanical effects mean that, below a critical temperature, they have zero electrical resistance. This property alone is more than enough to spark the imagination.

A current that could flow forever without losing any energy means transmission of power with virtually no losses in the cables. When renewable energy sources start to dominate the grid and high-voltage transmission across continents becomes important to overcome intermittency, lossless cables will result in substantial savings.

What’s more, a superconducting wire carrying a current that never, ever diminishes would act as a perfect store of electrical energy. Unlike batteries, which degrade over time, if the resistance is truly zero, you could return to the superconductor in a billion years and find that same old current flowing through it. Energy could be captured and stored indefinitely!

An interview on rejuvenation science, advocacy, and more with Reason from the blog Fight Aging!.


Most people interested in rejuvenation and life extension are familiar with Fight Aging!, one of the very first rejuvenation advocacy blogs dating back all the way to the early 2000s; if you’re one of them, then you certainly are familiar with Reason, the man behind FA!.

Over the years, Reason has been a patient yet relentless advocate, acting not only as an information provider for the public but also helping out innumerable organizations and companies in the field of rejuvenation biotechnology in financial and other ways. Back in the day when SRF didn’t exist yet, Reason was a volunteer for Methuselah Foundation; eventually, he helped fund companies such as Oisìn Biotechnologies, CellAge, and LysoCLEAR; and, earlier this month, Reason and Bill Cherman co-founded Repair Biotechnologies, a company focused on gene therapy for rejuvenation, as announced on FA!.

Bill Cherman is an investor in the rejuvenation community who, just like Reason, has contributed to development of many ventures in the field. He is a holder of a gold medal in the Brazilian Mathematics Olympiad, a BA in economics, and a candidate in the Master of Biotechnology Enterprise and Entrepreneurship program at Johns Hopkins. He founded Front Seat Capital, a venture capital firm looking to invest in startups with the potential to change the world.

Billionaire Elon Musk says he’s almost completed a tunnel under a Los Angeles suburb to test a novel transportation system that would scoot commuters underground on electric sleds called skates.

Musk tweeted Thursday that, pending regulatory approvals, free rides will be offered to the public in a few months. He also posted an Instagram video of the interior of the tunnel.

Last year, the Hawthorne City Council approved an approximately 2-mile (3.2-kilometer) test tunnel from Musk’s SpaceX rocket plant to a point east of Los Angeles International Airport.

Australia’s recycling crisis needs us to look into waste management options beyond just recycling and landfilling. Some of our waste, like paper or organic matter, can be composted. Some, like glass, metal and rigid plastics, can be recycled. But we have no immediate solution for non-recyclable plastic waste except landfill.

At a meeting last month, federal and state environment ministers endorsed an ambitious target to make all Australian packaging recyclable, compostable or reusable by 2025. But the ministers also showed support for processes to turn our into energy, although they did not specifically discuss plastic waste as an energy source.

The 100% goal could easily be achieved if all packaging were made of paper or wood-based materials. But realistically, plastic will continue to dominate our packaging, especially for food, because it is moisture-proof, airtight, and hygienic.

Sustainable biological filters called slow sand filters have been used to filter drinking water since the 1800s. They don’t use any chemicals, create no waste and use very little energy. However, technologies that meet modern requirements for control, monitoring and time-efficiency have become popular, while biological water treatment has been less favoured, since little has been understood about how it works. New research from Lund University in Sweden shows that not only are the older filters more efficient cleaners – they could be making a comeback soon with the help of new technology.

Older are more effective than new ones, a unique field study at a water treatment facility in southern Sweden shows. This is because the old filters have had the time to develop a specific ecosystem of hungry bacteria that purify the water. The water is cleaned not only by mechanical filtering by the grains of sand, but by considerably smaller helpers as well.

The fact that sand filters contain microorganisms was already known. However, it was believed that sand filters helped to reduce the number of bacteria, which is not the case.
