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.

Memory Successfully Boosted In Humans

Posted by in categories: biotech/medical, cyborgs, mathematics, neuroscience

Scientists from Wake Forest Baptist Medical Center partnered with researchers from the University of Southern California to develop an innovative procedure to give hope to people struggling with remembering important information. A new implant uses a person’s own memory patterns in order to boost the brain’s natural ability to encode those memories and recall them quickly. There has been a reported 35 to 37 % increase in short-term memory performance.

“This is the first time scientists have been able to identify a patient’s own brain cell code or pattern for memory and, in essence, ‘write in’ that code to make existing memory work better, an important first step in potentially restoring memory loss,” said the study’s lead author Robert Hampson, Ph.D., professor of physiology/pharmacology and neurology at Wake Forest Baptist.

Epilepsy patients from Wake Forest Baptist were surgically implanted with electrodes in the various parts of their brains. The electronic prosthetic system is based on a multi-input-multi-output (or MIMO) mathematical model to influence the patterns of neurons firing within the hippocampus.

Mad Scientists Want to 3D Print Every Dead Person Back to Life

Posted by in categories: 3D printing, life extension, mathematics, quantum physics, transhumanism

This major religious site suggests I’m part of a group of mad scientists, but Quantum Archaeology is a very interesting idea that more people should ponder. The article also highlights the challenge of #transhumanism vs. religion and conservative attitutes: http://www.lifenews.com/2018/03/12/mad-scientists-want-to-3-…k-to-life/ #transhumanism


But the self-described secular transhumanist is perfectly serious in his posturing about the future of technology, life and death. Within 50 years, he believes scientists may be able to bring back people from the dead.

“After all, everything is matter and energy. And human life, human thoughts and human existence are mathematical, determinable calculations of that subatomic world of matter and energy,” Istvan writes.

At least 200 candidates with previous careers in science, technology, engineering and math announced bids for some of the nation’s roughly 7,000 state legislature seats as of Jan. 31, according to data that 314 Action, a political action committee, shared exclusively with HuffPost.


This comes at a time when there’s only one Ph.D. scientist in Congress.

Real-world intercontinental quantum communications enabled by the Micius satellite

Posted by in categories: encryption, internet, mathematics, quantum physics, security, space

A joint China-Austria team has performed quantum key distribution between the quantum-science satellite Micius and multiple ground stations located in Xinglong (near Beijing), Nanshan (near Urumqi), and Graz (near Vienna). Such experiments demonstrate the secure satellite-to-ground exchange of cryptographic keys during the passage of the satellite Micius over a ground station. Using Micius as a trusted relay, a secret key was created between China and Europe at locations separated up to 7,600 km on the Earth.

Private and secure communications are fundamental for Internet use and e-commerce, and it is important to establish a secure network with global protection of data. Traditional public key cryptography usually relies on the computational intractability of certain mathematical functions. In contrast, quantum key distribution (QKD) uses individual light quanta (single photons) in quantum superposition states to guarantee unconditional security between distant parties. Previously, the quantum communication distance has been limited to a few hundred kilometers due to optical channel losses of fibers or terrestrial free space. A promising solution to this problem exploits satellite and space-based links, which can conveniently connect two remote points on the Earth with greatly reduced channel loss, as most of the photons’ propagation path is through empty space with negligible loss and decoherence.

A cross-disciplinary multi-institutional team of scientists from the Chinese Academy of Sciences, led by Professor Jian-Wei Pan, has spent more than 10 years developing a sophisticated satellite, Micius, dedicated to quantum science experiments, which was launched on August 2016 and orbits at an altitude of ~500 km. Five ground stations in China coordinate with the Micius satellite. These are located in Xinglong (near Beijing), Nanshan (near Urumqi), Delingha (37°22’44.43’‘N, 97°43’37.01” E), Lijiang (26°41’38.15’‘N, 100°1’45.55’‘E), and Ngari in Tibet (32°19’30.07’‘N, 80°1’34.18’‘E).

This Captivating Sci-Fi Short Film Was Randomly Generated By a Computer

Posted by in categories: alien life, computing, mathematics

We wouldn’t blame you for thinking that Julius Horsthuis spent weeks designing and animating his sci-fi short, Fraktaal, using 3D software. But as the artist reveals, “It so happens that I’m a lazy animator.” So he instead relied on complex mathematical fractal patterns to automatically generate the alien worlds and cities visited in his film.

Mathematics, rejuvenation, and immortality walk into a bar…

Posted by in categories: biotech/medical, life extension, mathematics

I often hear the claim that death is a statistical certainty. This is my mathematical take at why this is not true, assuming the defeat of ageing, and no, being immortal is not required.


If a fully rejuvenated person was hit by a train at full speed, I can promise you they would stand the same pathetically low chances of ever being reassembled into a single, barely functional piece as any non-rejuvenated person of any age. Keeping that in mind, if anyone tried to sell me rejuvenation as ‘immortality’, rest assured I would demand to see the manager right away.

On a different yet unexpectedly related note, if I had a nickel for every time I heard or read something along the lines of ‘death is inevitable because probability’, I could donate so much money to LEAF the IRS would start thinking they’re a bit too well off for a charity.
