The hidden mechanics of abrupt transitions: Superconducting networks show how tiny changes trigger system collapse

Why do some changes in nature unfold gradually, while others occur in the blink of an eye? Rust forming on metal is a slow, steady process that takes days or even weeks to become visible. By contrast, a power grid can collapse in mere seconds. What accounts for this difference?

A research team at Bar-Ilan University has uncovered a surprising mechanism behind these abrupt transitions, a hidden spontaneous sequence of micro-scale events that gradually destabilize a system until it snaps. Their discovery sheds new light on how behave near critical tipping points and offers a new way to anticipate and perhaps even prevent catastrophic failure.

In their study just published in Nature Communications, the team led by Professors Shlomo Havlin and Aviad Frydman—alongside BIU researchers Ira Volotsenko, Yuval Sallem, and Nahala Yadid, and postdoctoral collaborators Bnaya Gross (Northeastern University) and Ivan Bonamassa (CEU Vienna)—investigated a novel engineered experimental system: interdependent superconducting networks.

Questions to inspire discussion.

🏭 Q: How much LFP cell production capacity does Tesla have in Nevada? A: Tesla’s Nevada facility has equipment for 7–8 GWh of LFP cell production across two production lines, potentially for EVe and grid storage cells.

Tesla Business and Sales.

📊 Q: What are the expectations for Tesla’s Q2 PND report? A: Troy Teslike estimates 356,000 deliveries, while analyst consensus is 385,000, but PND reports are becoming less significant for Tesla’s business model.

💰 Q: What’s crucial for Tesla to become a multi-trillion dollar company? A: Unsupervised FSD rollout and Optimus sales at scale are key, not just increased car or megapack sales.

🇨🇳 Q: How are Tesla’s China sales performing? A: Latest week sales were 20,684 units, down 4.9% QoQ and 11% YoY, but year-to-date figures show Tesla China is closing the gap, down only 4.6% YoY.

Resonant frequencies reveal a map for optimizing single-atom catalysts

Using nuclear magnetic resonance, researchers at ETH Zurich have studied the atomic environments of single platinum atoms in solid supports as well as their spatial orientation. In the future, this method can be used to optimize the production of single-atom catalysts.

Mimicking the benefits of exercise with a single molecule

Capital Medical University, in collaboration with the Chinese Academy of Sciences, reports that betaine, a molecule produced in the kidney and enhanced through sustained exercise, operates as a potent inhibitor of inflammatory and aging-related pathways.

Regular physical activity boosts health across cardiovascular, metabolic, and neurological systems. Scientists have traced improvements in , , clearing of senescent cells and to consistent physical activity. Earlier animal studies suggested that long-term exercise can delay aging processes and reduce vulnerability to chronic disease.

Precise molecular explanations for how sustained exercise reshapes human biology remain incomplete. Many investigations have focused on single biomarkers or isolated tissues, leaving a need for systematic maps that can connect exercise to measurable physiological benefits. Specific factors capable of mimicking exercise’s protective effects without requiring continuous physical exertion have remained unclear.

Blood stem cell mutations linked to lower risk of late-onset Alzheimer’s disease

A study published in Cell Stem Cell reveals that some mutations in blood stem cells might help protect against late-onset Alzheimer’s disease.

A team led by researchers at Baylor College of Medicine discovered that both a mouse model and people carrying blood stem cells with mutations in the gene TET2, but not in the gene DNMT3A, had a lower risk of developing Alzheimer’s disease. Their study proposes a mechanism that can protect against the disease and opens new avenues for potential strategies to control the emergence and progression of this devastating condition.

“Our lab has long been studying blood stem cells, also called ,” said lead author Dr. Katherine King, professor of pediatrics— and a member of the Center for Cell and Gene Therapy and the Dan L Duncan Comprehensive Cancer Center at Baylor. She is also part of Texas Children’s Hospital.

Wearable X-ray-detecting fabric offers a flexible alternative to current imaging tech

Since their discovery by Wilhelm Roentgen in 1895, X-rays have become a staple of modern medical care, from imaging teeth and broken bones to screening for the early signs of breast cancer.

The most common type of X-ray detector used in medical imaging today utilizes materials known as scintillators, which are made of inorganic and rigid compounds. This inherent lack of flexibility limits their applications and often requires patients to contort their bodies to accommodate unyielding medical equipment.

This rigidity has created a demand among researchers and the for scintillating materials that are robust, efficient, and flexible. Past attempts to meet this demand, however, have had to sacrifice durability and efficiency for flexibility. An innovative fabric made of flexible inorganic fibers shows remarkable promise and may meet all three requirements.

Surprising discovery shows a strong link between Earth’s magnetic field and atmospheric oxygen levels

Every breath we take in contains 21% oxygen, the gas that makes life on Earth possible. Oxygen, in its combined oxide state, has always been abundant in Earth’s crust, but elemental diatomic oxygen became part of our atmosphere around 2.4 to 2.5 billion years ago as a gift from cyanobacteria, which triggered the Great Oxidation Event and breathed life into Earth.

A joint venture between NASA Goddard Space Flight Center and the University of Leeds discovered that the Earth’s magnetic field strength and atmospheric oxygen levels over the past 540 years have seemed to spike and dip at the same time, showing a strong, statistically significant correlation between the two.

This correlation could arise from unexpected connections between geophysical processes in Earth’s deep interior, redox reactions on Earth’s surface, and biogeochemical cycling.

Google just bought 200 megawatts of fusion energy that doesn’t even exist yet

Tech giant Google is investing money into a futuristic nuclear fusion plant that hasn’t been built yet but someday will replicate the energy of the stars. It’s a sign of how hungry big tech companies are for a virtually unlimited source of clean power that is still years away.

Google and Massachusetts-based Commonwealth Fusion Systems announced a deal Monday in which the tech company bought 200 megawatts of power from Commonwealth’s first commercial fusion plant, the same amount of energy that could power roughly 200,000 average American homes.

Commonwealth aims to build the plant in Virginia by the early 2030s. When it starts generating usable fusion energy is still TBD, though the company believes they can do it in the same timeframe.
