Physicists create powerful magnets to de-freeze quantum computing

Posted by in categories: computing, health, quantum physics

Quantum computing has the potential to revolutionize the world, allowing massive health and science computation problems to be solved exponentially faster than by classic computing. But quantum computers have a big drawback—they can only operate in subzero temperatures.

“In order to make quantum computers work, we cannot use them at room temperature,” said Ahmed El-Gendy, Ph.D., an associate professor of physics at The University of Texas at El Paso. “That means we will need to cool the computers and cool all the materials, which is very expensive.”

Now, physicists at The University of Texas at El Paso believe they have made a in that regard. Led by El-Gendy, the team has developed a highly magnetic quantum computing material—100 times more magnetic than pure iron—that functions at regular temperature. The material is described in a summer issue of the journal Applied Physics Letters.

Pig kidney works a record 2 months in donated body, raising hope for animal-human transplants

Posted by in category: biotech/medical

For a history-making two months, a pig’s kidney worked normally inside a brain-dead man. And while the dramatic experiment ended this week, it’s raising hope for eventually testing pig kidneys in living patients.

We’ve Been Misreading a Major Law of Physics For The Past 300 Years

Posted by in categories: mathematics, physics

When Isaac Newton inscribed onto parchment his now-famed laws of motion in 1,687, he could have only hoped we’d be discussing them three centuries later.

Writing in Latin, Newton outlined three universal principles describing how the motion of objects is governed in our Universe, which have been translated, transcribed, discussed and debated at length.

But according to a philosopher of language and mathematics, we might have been interpreting Newton’s precise wording of his first law of motion slightly wrong all along.

A linear path to efficient quantum technologies

Posted by in categories: computing, engineering, quantum physics

Researchers at the University of Stuttgart have demonstrated that a key ingredient for many quantum computation and communication schemes can be performed with an efficiency that exceeds the commonly assumed upper theoretical limit—thereby opening up new perspectives for a wide range of photonic quantum technologies.

Quantum science has not only revolutionized our understanding of nature—it is also inspiring groundbreaking new computing, communication and sensor devices. Exploiting in such “quantum technologies” typically requires a combination of deep insight into the underlying quantum-physical principles, systematic methodological advances, and clever engineering.

And it is precisely this combination that researches in the group of Prof. Stefanie Barz at the University of Stuttgart and the Center for Integrated Quantum Science and Technology (IQST) have delivered in a recent study, in which they have improved the efficiency of an essential building block of many quantum devices beyond a seemingly inherent limit. The work is published in the journal Science Advances.

‘We Saw So Many Doctors’: A Mother Says ChatGPT Accurately Diagnosed Her Son’s Medical Condition After 17 Doctors Couldn’t

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

I hope this isn’t a duplicate but that’s amazing! I dunno if I shared the latest Google cloud security conference? It’s an hour and they’re using advanced AI and even collaborating with Israel I think.


After 17 medical consultations led to dead ends, a mother turned to ChatGPT for help. Then, AI came up with a diagnosis.

Certain proteins in breast milk found to be essential for a baby’s healthy gut

Posted by in categories: biotech/medical, evolution, health

Researchers have shown that high concentrations of key proteins in human breast milk, especially osteopontin and κ-casein, are associated with a greater abundance of two species of bacteria in the gut of babies: Clostridium butyricum and Parabacteroides distasonis, known to be beneficial for human health and used as probiotics. These results suggest that proteins in breast milk influence the abundance of beneficial gut microbes in infants, playing an important role in early immune and metabolic development

More than 320 million years of mammalian evolution has adapted breast milk to meet all the physiological needs of babies: it contains not only nutrients, but also hormones, antimicrobials, digestive enzymes, and growth factors. Furthermore, many of the proteins in breast milk, for example casein and milk fat globule membrane proteins, aren’t just sources of energy and molecular building blocks, but also directly stimulate immunity, at least under preclinical conditions.

Google has a new tool to outsmart authoritarian internet censorship

Posted by in categories: encryption, government, internet

Its Outline VPN can now be built directly into apps—making it harder for governments to block internet access, particularly during protests.

Google is launching new anti-censorship technology created in response to actions by Iran’s government during the 2022 protests there, hoping that it will increase access for internet users living under authoritarian regimes all over the world.

Jigsaw, a unit of Google that operates sort of like an internet freedom think tank and that creates related products, already offers a suite of anti-censorship tools including Outline, which provides free, open, and encrypted access to the internet through a VPN. Outline uses a protocol that makes it hard to… More.

This driverless car company is using chatbots to make its vehicles smarter

Posted by in categories: robotics/AI, transportation

Self-driving car startup Wayve can now interrogate its vehicles, asking them questions about their driving decisions—and getting answers back. The idea is to use the same tech behind ChatGPT to help train driverless cars.

The company combined its existing self-driving software with a large language model, creating a hybrid model it calls LINGO-1. LINGO-1 synchs up video data and driving data (the actions that the cars take second by second) with natural-language descriptions that capture what the car sees and what it does.

AI just beat a human test for creativity. What does that even mean?

Posted by in category: robotics/AI

Large language models are getting better at mimicking human creativity. That doesn’t mean they’re actually being creative, though.

AI is getting better at passing tests designed to measure human creativity. In a study published in Nature Scientific Reports today, AI chatbots achieved higher average scores than humans in the Alternate Uses Task, a test commonly used to assess this ability.

This study will add fuel to an ongoing debate among AI researchers about what it even means for a computer to pass tests devised for humans. The findings do not necessarily indicate that AIs are developing an ability to do something uniquely human. It could just be that AIs can pass creativity tests, not that… More.
