Harvard Rewinds the Biological Clock of Time
Posted by Nicholi Avery in categories: bioengineering, biological, DNA, health, life extension, science, transhumanism
Investigators at Harvard Medical School have identified the key cellular mechanisms behind vascular aging and its effects on muscle health, and they have successfully reversed the process in animals.
The scientists used a chemical compound that’s an NAD+ booster called NMN which plays a critical role in repairing cellular DNA as well as maintaining cell vitality to test what would happen.
Could reversing the aging of blood vessels hold the key to restoring youthful vitality? If the old adage “you are as old as your arteries” reigns true then the answer is yes, at least in mice.

‘Til Deletion Do Us Part’: Discovering Love in a Virtual Future
Posted by B.J. Murphy in categories: biological, robotics/AI, virtual reality
What does it mean to fall in love in the 21st century? Originally, the number of people you could fall in love with were limited to the amount that lived within relative close proximity of you (a few miles, at best). In today’s world, however, it isn’t that uncommon for people to fall in love online.
As we move forward into a future of VR and AI, how might our abilities to fall in love change in a world where non-biological life is teeming just as much as biological life?

The Neurogenesis Debate
Written by Nicholi Avery
On March 7 2018, a study was published in the highly esteemed journal Nature by an international team of scientists claiming that #neurogenesis starts to rapidly decline in the #human brain as early as 13 years old and becomes undetectable in adults. This rocked the scientific community as there has been a long-established theory that neurogenesis takes place throughout the course of life in the mammalian #brain. Until the 1990s, neurologists were practicing their profession under the doctrine established in the late 19th to early 20th century by the prominent histologist Ramon y Cajal, often referred to as a god of neuroscience;

Best of last week: Flux capacitor invented, a better 3D printer and the true benefits of vitamins
Posted by Shane Hinshaw in categories: 3D printing, biological, cosmology, genetics, health, quantum physics, space travel
It was a good week for physics as a team with members from Australia and Switzerland invented a flux capacitor able to break time-reversal symmetry. They proposed a device based on quantum tunneling of magnetic flux around a capacitor. And another team with members from across the U.S. reported on a gravitational wave event that likely signaled the creation of a black hole—the merger of two neutron stars.
In biology news, a team of engineers led by Sinisa Vukelic invented a noninvasive technique to correct vision. Like LASIK, it uses lasers but is non-surgical and has few side-effects. And an international team of researchers found what they describe as the mother of all lizards in the Italian Alps, the oldest known lizard fossil, from approximately 240 million years ago. Also, a team at the University of Sydney found that walking faster could make you live longer. People do not even need to walk more, the team reported, they just need to pick up the pace of their normal stride to see an improvement in several health factors. And a team from Cal Poly Pomona discovered how microbes survive clean rooms and contaminate spacecraft—and it involved the cleaning agents themselves.
In other news, a team of researchers from the University of California and the University of Southern Queensland announced that they had identified 121 giant planets that may have habitable moons. And a team at Stanford University found that wars and clan structure might explain a strange biological event that occurred 7,000 years ago—male genetic diversity appeared to collapse for a time. Also, a team of researchers from MIT and Harvard University report the development of a 3D printer that can print data sets as physical objects—offering far more realistic, nearly true-color renderings.

Heroes of Innovation: Zoltan Istvan
Posted by Zoltan Istvan in categories: biological, geopolitics, transhumanism
I’ll be speaking at the exciting Future Flux Festival on the Heroes of Innovation program section on June 15 in the Netherlands. Come join me! https://www.futurefluxfestival.nl/…/heroes-of-innovation-z…/ #transhumanism
Transhumanism is the field of merging human beings with machines and radical science. The field has grown from fringe to a nearly mainstream social movement. Today, there are tens of millions of transhumanists around the world, many who are scientists and technologists focusing on overcoming biological death with innovation. The movement got a major push when Zoltan Istvan, a former journalist for National Geographic, published his bestselling philosophical novel The Transhumanist Wager. In 2016 Zoltan ran for the Presidency of the United States as the nominee of the Transhumanist Party. His campaign was broadly covered in major media for nearly two years, and it helped spearhead the transformation of transhumanism into a thriving worldwide phenomenon. Always wanted to know more about transhumanism? See you at the Future Flux Festival!
Zoltan Istvan is also part of our Heroes of Innovation panel. After their presentations you can ask our panel anything. Take a deep dive into the minds of these great innovators!

Eco-friendly water treatment works best with experienced bacterial flora
Posted by Bill Kemp in categories: biological, sustainability
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 sand filters 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.

Biological and Artificial Intelligence
Posted by Peter Morgan in categories: biological, neuroscience, robotics/AI, transhumanism
We all feel overwhelmed by the speed at which new computing technologies are being thrown at us, but we haven’t seen anything yet. With the upcoming breakthroughs in Artificial Intelligence technology, today’s computers will look like prehistoric tools, within just a few years. Systems are likely to follow suit, bringing us closer to strong AI, a moment when machines will be as smart as any human being. The question many fear is what will happen if and when machines become much brighter than us? In “What’s on their mind?” system consultant Serge Van Themsche describes through an engaging discussion with his driverless car, the main AI issues any concerned citizen should know about. This conversation resorts to hard and soft disciplines to better explain AIn this book you will get to understand: — What are biological and artificial knowledge, intelligence, and self-consciousness? — Which new neuroscience evidence shows how our brain programs data coming from our senses? — How can simple formulas, such as 2 power of i −1, explain how our neurons connect? — Can emotions be computable? — Can machines already create knowledge without any human interference? — Why must the computer industry mimic as closely as possible the brain functionalities to develop intelligent androids? — Why will AI be based on a discrete world rather than a digital one? — Will humans become super beings? This book will enable every reader, with or without a scientific or philosophical background, to grasp the similarities and differences between brains and computers. By doing so, he or she will not only figure out the likely paths AI will follow but also how humans will use these new technologies to transform themselves into super beings. Even though not all readers might be looking forward to Transhumanism, the movement that apprehends these modifications, they can get prepared for this future co-existence with smart robots. In the meantime, they will at least, gain a clear understanding of how their own mind works and why they become knowledgeable, intelligent, and self-aware.
