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.

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.

Happy birthday to dr. aubrey de grey bigsmile


How many biologists does it take to make nontrivial progress on an unsolved mathematical problem for the first time in nearly 70 years? The answer is one, at least if the biologist is Dr. Aubrey de Grey, the pioneer of the repair approach to aging.

Yes, you read that right. Today, in occasion of Dr. de Grey’s birthday, we’ve decided to take a short break from biology and rejuvenation to tell our readers about the recent scientific achievement of one of the world’s most famous biogerontologists—unexpectedly, but pleasantly so, in the field of mathematics.

The chromatic number of the plane

Don’t worry if mathematics is not really your thing; we’ll keep it simple. Imagine that you have an infinitely large plane, where all points located at distance 1 from one another are connected by a straight line; any number of so-connected points, finitely or infinitely many, is called a graph. Further suppose that, for some reason, you wanted to color each point in such a fashion that no two connected points have the same color. How many different colors would you need to do this for the entire plane?

MIT engineers have developed a continuous manufacturing process that produces long strips of high-quality graphene.

The team’s results are the first demonstration of an industrial, scalable method for manufacturing high-quality that is tailored for use in membranes that filter a variety of molecules, including salts, larger ions, proteins, or nanoparticles. Such membranes should be useful for desalination, biological separation, and other applications.

“For several years, researchers have thought of graphene as a potential route to ultrathin membranes,” says John Hart, associate professor of mechanical engineering and director of the Laboratory for Manufacturing and Productivity at MIT. “We believe this is the first study that has tailored the manufacturing of graphene toward membrane applications, which require the graphene to be seamless, cover the substrate fully, and be of high quality.”

Researchers in the US and UK examined an existing enzyme which had occurred naturally in landfill sites and was able to slowly digest man-made plastics.

But in the course of testing the enzyme’s origins, the researchers made biological changes to it that turbo-charged its ability to digest plastics, according to Britain’s University of Portsmouth.

According to The Guardian, the enzyme starts breaking down plastic in a matter of days, a process which would take centuries under normal conditions.
