Using mock burglaries, researchers investigate a way to catch criminals using the microbes they leave behind. Could your microbiome give you away?

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;

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.

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!

You may have forgotten about the nucleolus since you took biology class, but scientists think this structure inside every cell in your body may play an important role in aging.

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.

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.

As humans, we are defined by, among other things, our desire to transcend our humanity. Mythology, religion, fiction and science offer different versions of this dream. Transhumanism – a social movement predicated on the belief that we can and should leave behind our biological condition by merging with technology – is a kind of feverish amalgamation of all four. Though it’s oriented toward the future, and is fuelled by excitable speculation about the implications of the latest science and technology, its roots can be glimpsed in ancient stories like that of the Sumerian king Gilgamesh and his quest for immortality.

Will humans ever conquer mortality by merging with technology? The 2018 Wellcome prize winner shares his favourite books on transhumanism, from a cyborg manifesto to a Don DeLillo novel.
