A bioengineered cornea can restore sight to blind people

Posted by in categories: bioengineering, humor

Sarcasm, and Hyperbole and a lot of general humor really hasn’t done well on the internet.

No matter how stupid, or off the wall an answer from a source is. There will be a bunch of people who believe it, and take action on it. When people take action on something the believe in, things can get very bad very quickly.

For some people just the spark of the idea is enough for them to put in the head the connecting pieces of some grand conspiracy, which they feel compelled to protect the world from.

The worst case Starlink scenario? We could be ‘right on the edge’ of Kessler syndrome

Posted by in categories: Elon Musk, internet, satellites

And cleaning up the resulting space debris would be like ‘collecting bullets’.

SpaceX’s Starlink mega-constellation is growing at rocket speed.

SpaceX CEO Elon Musk recently announced that the private space company expects over 4,200 Starlink satellites in operation within 18 months\.

A flexible, rod-driven soft robot for biomedical applications

Posted by in categories: biotech/medical, robotics/AI

Soft robots that can complete tasks with high efficiency, accuracy and precision could have numerous valuable applications. For instance, they could be introduced in medical settings, helping doctors to carry out complex surgical procedures or assisting elderly and vulnerable patients during rehabilitation.

Soft robots are more flexible and can deform more. This can result in an increased dexterity (i.e., better manual skills when completing tasks), as well as in a reduction of payload (i.e., the capacity to carry a load), because they can produce smaller forces than rigid robotic systems.

Researchers at National University of Singapore and Beijing Jiaotong University have recently developed a new rod-driven soft robot (RDSR) that operates through push and pull movements. This robot, presented in a paper published in the IEEE Robotics and Automation Letters, combines the mechanisms of two previously created by members of the research group.

Faked Crystallography

Posted by in categories: computing, transportation

I’ll admit that I didn’t see this one coming: Retraction Watch is reporting that the Cambridge Crystallographic Data Center (CCDC), the world’s main repository of small-molecule crystal data, is on the way to pulling nearly a thousand deposited crystal structures because they appear to have been faked. A preprint from earlier this year from David Bimler flagged what seems to be a paper-mill operation flooding out bogus papers on metal-organic frameworks: hundreds and hundreds of weirdly worded manuscripts on nonexistent MOFs and their imaginary applications, full of apparently randomly selected “references” to the rest of the literature. And these things depositited crystal data with the CCDC, which is the step that I really didn’t expect.

After all, anyone who studies the scientific literature has (especially in recent years) seen these auto-generated papers full of crap. But faked crystal structure files? That’s nasty. The record of these papers shows a sudden jump in 2020 and 2021, leading Bimler to wonder:

The dates paint a picture of accelerating publication, as if a small-scale cottage industry had been scaled up to a production line with a larger staff. One can imagine crystallographers initially ghostwriting manuscripts as a favour for friends, moonlighting from their day job, and becoming progressively more professional, though this must remain speculation.

We Might Already Speak the Same Language As ET

Posted by in categories: alien life, existential risks, mathematics, quantum physics

Alien communication could utilize quantum physics, so SETI needs a new way to listen.

The Fermi paradox, the “where is everybody?” puzzle, is a persistent question in the search for life in the universe. It asks why, if life is not exceedingly rare in the cosmos, it hasn’t shown up on our doorstep. Equally we might ask why we haven’t even heard from alien life, through radio signals or any other means. A part of the answer could be that our present work on the search for extraterrestrial intelligence is actually very limited. Estimates show that we’ve only examined the equivalent of a hot tub of water compared to all the world’s oceans in our combing through the electromagnetic information that rolls in from the cosmos.1

If you’re a glass-half-full kind of person you’ll see this as an opportunity, but the problem is that we don’t actually know what might be filling the glass in the first place. The vast majority of SETI studies look for structure in electromagnetic radiation, whether in amplitude or frequency modulations of radio waves, or regularity in pulses of light, or in multi-wavelength correlations. In other words, we assume that information might be sailing past us in representations built using classical physics. But what if that’s just wrong?

World’s Fastest 2-Qubit Gate: Breakthrough for the Realization of Ultrafast Quantum Computers

Posted by in categories: computing, particle physics, quantum physics

A research team succeeded in executing the world’s fastest two-qubit gate (a fundamental arithmetic element essential for quantum computing) using a completely new method of manipulating, with an ultrafast laser, micrometer-spaced atoms cooled to absolute zero temperature. For the past two decade.

Absolute zero is the theoretical lowest temperature on the thermodynamic temperature scale. At this temperature, all atoms of an object are at rest and the object does not emit or absorb energy. The internationally agreed-upon value for this temperature is −273.15 °C (−459.67 °F; 0.00 K).
