The Wolfram Institute will pursue opportunities in scientific research based on a new multicomputational paradigm found during a project to develop a fundamental theory of physics.
A new study from the Blavatnik Institute finds that intense exercise and fasting activate hormones that boost cells’ capacity to dispose of defective proteins, which clog up the cell, interfere with its functions, and, over time, precipitate diseases including neurodegenerative conditions such as ALS and Alzheimer’s.
In case you hadn’t heard, the universe is governed by four fundamental forces. But when it comes to understanding nature at almost any level larger than a nucleus and smaller than a planet, …
In an important step for open science, CERN has been selected to host a new phase of Open Research Europe (ORE) , an initiative supported by the European Commission and a new funding consortium of European national funding agencies and research organisations. Aligned with the Action Plan for Diamond Open Access (2022)…
The long view of economic history says we're in the midst of a huge, unsustainable acceleration. What happens next?
That’s an easy go: energy is the amount of (on) my electricity bill, or maybe of (on) my natural gas bill. If I am very concentrated, I might add that it is also the money I spend at the gasoline pump, and if I am even more concentrated I will suggest that it might have something to do with the filling up of my…
A guide to the operating principles, techniques and technology in lidar systems for self driving cars.
Dissing Fourier, exploring the Hadamard-Walch transform, and making square-wave spectrograms.
AI and the ruliad in the Wolfram Physics Project provide a new way to consider how alien minds might perceive the world. Stephen Wolfram explains how this artificial neuroscience experiment works.
A new type of vaccine developed by researchers at the University of Chicago’s Pritzker School of Molecular Engineering (PME) has shown in the lab setting that
People disabled by a stroke demonstrated substantial recovery long after the event when modified adult stem cells were injected into their brains.
The NASA/ESA Hubble Space Telescope has captured the sharpest and biggest image ever taken of the Andromeda galaxy — otherwise known as Messier 31. The enormous image is the biggest Hubble image ever released and shows over 100 million stars and thousands of star clusters embedded in a section of the galaxy’s…
This article was originally written in 2014, but has had some minor improvements in December 2017 and January 2018 when I received some useful feedback after the article had unexpectedly been posted on Hacker News in December 2017.
According to one estimate, there are around 25 blimps worldwide. What will it take to bring back these majestic beasts of the sky?
In recent years there has been a noticeable uptick in publicized incidents of turbulence affecting commercial aircraft. These events, sometimes unexpected and severe, have led to passenger injuries, emergency landings, and a recent rare fatality. Turbulence can be caused by a variety of factors, from the mixing of air…

The first scientific pictures from the Euclid satellite mission have revealed more than 1,500 billion orphan stars scattered throughout the Perseus cluster of galaxies.
More than 60 percent of the United States is experiencing drought conditions, with more than 20 percent in an extreme drought. Andrew Ellis, a climatologist at Virginia Tech said the current conditions are among the worst in decades because the combination of intensity and aerial coverage is rare. He explained why…
A light-by-light scattering candidate event measured in the ATLAS detector. (Image: ATLAS Collaboration/CERN) Geneva, 14 August 2017. Physicists from the ATLAS experiment at CERN have found the first direct evidence of high energy light-by-light scattering, a very rare process in which two photons – particles of light…
Research Highlights: An analysis of data from a long-running study of more than 11,000 adults from four diverse communities in the United States has found that adults who had high blood pressure while both seated upright and lying supine (flat on ...
New research from the University of Kentucky’s Sanders-Brown Center on Aging shows compelling evidence that the cognitive impairments observed in long COVID patients share striking similarities with those seen in Alzheimer’s disease and related dementias.
On December 24th, AES Andes, a subsidiary of the US power company AES Corporation, submitted a project for a massive industrial complex for environmental impact assessment. This complex threatens the pristine skies above ESO’s Paranal Observatory in Chile’s Atacama Desert, the darkest and clearest of any astronomical…

a cheap and bloody experiment
I once heard a saying – “Don’t feel pity on plants because they can’t move. Feel pity on us, because we have to”. I really didn’t have an appreciation for what this meant until the COVID pandemic hit, which restricted my movement for a couple of years, and I decided to spend some of my new-found time at home learning…
You probably that planets go around the sun in elliptical orbits. But do you know why? In fact, they’re moving in circles in 4 dimensions. But when these circles are projected down to 3-dimen…
