Ergodicity Breaking Provably Robust to Arbitrary Perturbations

Posted by in categories: law, quantum physics

We present a new route to ergodicity breaking via Hilbert space fragmentation that displays an unprecedented level of robustness. Our construction relies on a single emergent (prethermal) conservation law. In the limit when the conservation law is exact, we prove the emergence of Hilbert space fragmentation with an exponential number of frozen configurations. These configurations are low-entanglement states in the middle of the energy spectrum and therefore constitute examples of quantum many-body scars. We further prove that every frozen configuration is absolutely stable to arbitrary perturbations, to all finite orders in perturbation theory.

Cybergang DarkGate Uses CAPTCHA to Spread Malware

HP Wolf Security’s latest threat insights disclosure put a spotlight on DarkGate – a group of web-based criminals using legal advertising tools to enhance their spam-based malware attacks.

The security report claims DarkGate has been operating as a malware provider since 2018, with an apparent shift in tactics last year of using legitimate advertisement networks “to track victims and evade detection.” The claims are that by using ad services, threat actors can analyze which lures generate clicks and infect the most users – helping them refine campaigns for maximum impact.

Debate simmers over when doctors should declare brain death

Posted by in categories: bioengineering, biotech/medical, ethics, law, neuroscience

Benjamin Franklin famously wrote: “In this world nothing can be said to be certain, except death and taxes.” While that may still be true, there’s a controversy simmering today about one of the ways doctors declare people to be dead.


Bioethicists, doctors and lawyers are weighing whether to redefine how someone should be declared dead. A change in criteria for brain death could have wide-ranging implications for patients’ care.

Stem Cell and Bone Marrow Transplants for Cancer

Posted by in categories: biotech/medical, law

Whether or not you can work during a stem cell transplant may depend on the type of job you have. The process of a stem cell transplant, with the high-dose treatments, the transplant, and recovery, can take many months. You will be in and out of the hospital during this time. Even when you are not in the hospital, sometimes you will need to stay near it, rather than staying in your own home.

You will be more tired and your ability to concentrate on work may be affected. You will be visiting the hospital two or three times a week after discharge. You may need to spend a few hours in the hospital for blood or platelet transfusions or replacing minerals in your body.

So, if your job allows, you may want to arrange to work remotely part-time. Many employers are required by law to change your work schedule to meet your needs during cancer treatment. Talk with your employer about ways to adjust your work during treatment. You can learn more about these laws by talking with a social worker.

Physicists discover time can flow both ways in materials

Posted by in categories: law, life extension, physics

For example, a video of a swinging pendulum would look the same if you played it backward. We see time as irreversible because of another law of nature, the second law of thermodynamics. This law says that the disorder in a system always increases. If the broken glass reassembled itself, the disorder would decrease.

The same law applies to the aging of materials. But physicists from Darmstadt have found out that this is not the case. They have discovered that the motion of molecules in glass or plastic can be reversed in time if you look at it from a special angle.

Astrophysicist ‘Fixes’ General Relativity by Throwing Out a Major Law

Posted by in categories: law, quantum physics

Albert Einstein was one smart cookie; there’s no doubt about it. But even he knew his general theory of relativity – the 21st century’s answer to Newton’s universal theory of gravity – wasn’t perfect.

Like the second-hand car you bought using your first paycheck, it does the job for day-to-day errands. Push it too hard up a steep hill or park it near a quantum strip mall, and that engine shudders to a standstill.

Peoples’ Friendship University of Russia astrophysics grad student Hamidreza Fazlollahi’s solution is to dive under the hood and see which components aren’t as essential as they seem.

After AI’s summer: What’s next for artificial intelligence?

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

For example, the New York Times states: “The AI industry this year is set to be defined by one main characteristic: A remarkably rapid improvement of the technology as advancements build upon one another, enabling AI to generate new kinds of media, mimic human reasoning in new ways and seep into the physical world through a new breed of robot.”

Ethan Mollick, writing in his One Useful Thing blog, takes a similar view: “Most likely, AI development is actually going to accelerate for a while yet before it eventually slows down due to technical or economic or legal limits.”

The year ahead in AI will undoubtedly bring dramatic changes. Hopefully, these will include advances that improve our quality of life, such as the discovery of life saving new drugs. Likely, the most optimistic promises will not be realized in 2024, leading to some amount of pullback in market expectations. This is the nature of hype cycles. Hopefully, any such disappointments will not bring about another AI winter.

AI can copy HANDWRITING — can you tell it apart from the real thing?

Posted by in categories: law, robotics/AI

AI tools like ChatGPT can draft letters, tell jokes and even give legal advice – but only in the form of computerized text.

Now, scientists have created an AI that can imitate human handwriting, which could herald fresh issues regarding fraud and fake documents.

AI Image Generators Are Spitting Out Copyrighted Characters, Raising Possibility of Catastrophic Lawsuit

Posted by in categories: entertainment, internet, law, robotics/AI

Companies like OpenAI and Midjourney have opened Pandora’s box, opening them up to considerable legal trouble by training their chatbots on the vastness of the internet while largely turning a blind eye to copyright.

As professor and author Gary Marcus and film industry concept artist Reid Southen, who has worked on several major films for the likes of Marvel and Warner Brothers, argue in a recent piece for IEEE Spectrum, tools like DALL-E 3 and Midjourney could land both companies in a “copyright minefield.”

It’s a heated debate that’s reaching fever pitch. The news comes after the New York Times sued Microsoft and OpenAI, alleging it was responsible for “billions of dollars” in damages by training ChatGPT and other large language models on its content without express permission. Well-known authors including “Game of Thrones” author George RR Martin and John Grisham recently made similar arguments in a separate copyright infringement case.
