Using a modular construction kit of tailor-made cell systems, the researchers hope to simulate various properties of biological systems in the future. The idea is that cells react to their environment and learn to act independently.
The first applications are already on the horizon: In the long term, artificial cell assemblies can be deployed as mini-factories to produce specific biomolecules, or as tiny micro-robot sensors that process information and adapt to their environments.
It’s now possible to image an entire fly brain in just a few days, according to a new study—this might sound like a long time, but is in fact an incredible accomplishment, when you consider that the process would otherwise take weeks.
Brains aren’t easy to study—the human brain, for example, contains over 80 billion cells linked via 7,000 connections each, according to the new study published in Science. Even the far smaller fly brains are an incredible challenge to study comprehensively. The new research combines two microscopy methods to image and examine brains like never before.
CERN has revealed plans for a gigantic successor of the giant atom smasher LHC, the biggest machine ever built. Particle physicists will never stop to ask for ever larger big bang machines. But where are the limits for the ordinary society concerning costs and existential risks?
CERN boffins are already conducting a mega experiment at the LHC, a 27km circular particle collider, at the cost of several billion Euros to study conditions of matter as it existed fractions of a second after the big bang and to find the smallest particle possible – but the question is how could they ever know? Now, they pretend to be a little bit upset because they could not find any particles beyond the standard model, which means something they would not expect. To achieve that, particle physicists would like to build an even larger “Future Circular Collider” (FCC) near Geneva, where CERN enjoys extraterritorial status, with a ring of 100km – for about 24 billion Euros.
Experts point out that this research could be as limitless as the universe itself. The UK’s former Chief Scientific Advisor, Prof Sir David King told BBC: “We have to draw a line somewhere otherwise we end up with a collider that is so large that it goes around the equator. And if it doesn’t end there perhaps there will be a request for one that goes to the Moon and back.”
“There is always going to be more deep physics to be conducted with larger and larger colliders. My question is to what extent will the knowledge that we already have be extended to benefit humanity?”
The study, published Friday in JAMA Network Open, looked county by county across the United States between 2013 and 2015. It found that where pharmaceutical companies spent more on meals, travel and speaking fees for doctors, there were more opioid prescriptions — and more fatal overdoses.
Question To what extent is pharmaceutical industry marketing of opioids to physicians associated with subsequent mortality from prescription opioid overdoses?
Findings In this population-based, cross-sectional study, $39.7 million in opioid marketing was targeted to 67 507 physicians across 2208 US counties between August 1, 2013, and December 31, 2015. Increased county-level opioid marketing was associated with elevated overdose mortality 1 year later, an association mediated by opioid prescribing rates; per capita, the number of marketing interactions with physicians demonstrated a stronger association with mortality than the dollar value of marketing.
This was the first part in an interview series with Scott Aaronson — this one is on quantum computing — other segments are on Existential Risk, consciousness (including Scott’s thoughts on IIT) and thoughts on whether the universe is discrete or continuous.

Speakers from Amazon, MIT, UC Berkeley, NASA and Harvard are on the docket.
Amazon announces a new re: Mars conference that will gather experts in machine learning, robotics, automation and space in Las Vegas.
Mechanical tension between tethered cells cues developing tissues to fold. Researchers can now program synthetic tissue to make coils, cubes and rippling plates.
