How people die vs. media coverage of death
Data collection and analysis by Hasan Al-Jamaly, Maximillian Siemers, Owen Shen, and Nicole Stone.
Notes on Resonance
Resonance occurs when two sources of excitation fall completely in sync, and reinforce one another endlessly. In this state, the sources convey an unbounded amount of energy over time.
Bret Victor Redesigns Classic Strogatz Paper (2011)
This page presents a scientific paper that has been redesigned as a sequence of illustrations with captions. This comic-like format, with tightly-coupled pictures and prose, allows the author to depict and describe simultaneously — show and tell.
How to Be a Systems Thinker
At the moment, I’m asking myself how people think about complex wholes like the ecology of the planet, or the climate, or large populations of human beings that have evolved for many years in separate locations and are now re-integrating. To think about these things, I find that you need something like systems theory…
Interactive computational neuroscience – part 1, spiking neurons
An interactive introduction to spiking neuron models -- all in the browser. Learn about modeling neurons as dynamical systems and the computational properties of neurons.
Progress on longstanding open problems
For those who haven’t seen it: Aubrey de Grey, better known to the world as a radical life extension researcher, on Sunday posted a preprint on the arXiv claiming to prove that the chromatic …
Breakthrough Announced in Dark Matter Detection Technology
This week, the Axion Dark Matter Experiment (ADMX) announced that it has achieved the necessary sensitivity to “hear” the telltale signs of dark matter axions.
A new JPEG format
The Joint Photographic Experts Group (JPEG), an international committee headed by an EPFL professor, has just unveiled JPEG XS. With this new format, the image-compression process uses less energy, and higher-quality images can be sent with low latency over broadband networks like 5G. JPEG XS will have applications in…
Before cancer kills, it cheats
Evolutionary biologist Athena Aktipis of Arizona State University delivered a lecture titled “Why Cancer is Everywhere” at the Harvard Museum of Natural History.
Berkeley offers its data science course online for free
Data science is increasingly popular at Berkeley because the world is increasingly data-driven
Planets evenly spaced on log scale
The distances to the planets are fairly evenly distributed on a logarithmic scale, not only in our solar system but in extrasolar systems as well.
Adult Neurogenesis – A Pointed Review
[I am not a neuroscientist and apologize in advance for any errors in this article. A recent study came out contradicting some of the claims mentioned here. See here for study, this comment for som…
The differences between tinkering and research (2016)
Some of us have academic degrees and fancy university jobs, and publish peer-reviewed papers in prestigious journals. Let's call these peopl...
Biologist E.O. Wilson suggests ‘moon shot’ conservation effort
Biologist E.O. Wilson suggests conserving half of the Earth to save species. He and former National Park Service Director Jonathan Jarvis discuss how to do that.
Nicotinamide riboside effects on aging similar to caloric restriction
Nicotinomide riboside (NR) mimics caloric restriction, kick-starting the same pathways responsible for reducing cardiovascular aging.
Poor Grades Tied to Class Times That Don’t Match Our Biological Clocks
Schedules of night owls, morning larks and daytime finches may predict their educational outcomes

Hubble finds first galaxy in the local universe without dark matter
An international team of researchers using the NASA/ESA Hubble Space Telescope and several other observatories have, for the first time, uncovered a galaxy in our cosmic neighbourhood that is missing most — if not all — of its dark matter. This discovery of the galaxy NGC 1052-DF2 challenges currently-accepted…
Gravitational attraction of stars and cows
One attempt at rationalizing astrology is to say that the gravitational effects of celestial bodies impact our bodies. To get an idea how hard the stars and planets pull on us, let's compare their gravitational attraction to that of cows at various distances. Newton's law of gravity says that the gravitational…
Applied Category Theory
It just became a lot easier to learn about applied category theory, thanks to this free book: • Brendan Fong and David Spivak, Seven Sketches in Compositionality: An Invitation to Applied Cate…
In field tests, device harvests water from desert air
You really can extract clean drinking water right from the air, even in the driest of deserts, MIT researchers have found. They’ve demonstrated a real-world version of a water-harvesting system based on metal organic frameworks, or MOFs, that they first described last year.
Hennessy and Patterson win Turing Award
Hennessy and Patterson pioneered a systematic, quantitative approach to the design and evaluation of computer architectures that has had enduring impact on the microprocessor industry. Their reduced instruction set computer (RISC) approach has led to lasting and repeatable principles that generations of architects…
Death of the sampling theorem?
tl;dr: A team from Columbia University led by Ken Shepard and Rafa Yuste claims to beat the 100 year old Sampling Theorem [1,2]. Apparently anti-aliasing filters are superfluous now because one can…
