Consider a material that doesn’t just “have” a certain property, but spontaneously creates it out of total chaos. That is the essence of what researchers found in a recent study on a specific metal called CeRu4Sn6.
This isn’t just a lab curiosity. By proving that quantum fluctuations (the tiny, frantic jitters of atoms) can work together with a material’s symmetry to create new phases, the researchers have provided a new “treasure map.”
Key Takeaway: You don’t always need solid building blocks (quasiparticles) to build a structure; sometimes, the “jitter” of quantum physics is enough to weave a new reality.
Examples of materials with non-trivial band topology in the presence of strong electron correlations are rare. Now it is shown that quantum fluctuations near a quantum phase transition can promote topological phases in a heavy-fermion compound.
RCT: Among adults with mTBI, targeted multidomain interventions and usual care behavioral management resulted in similar improvements in overall symptom severity and patient-perceived recovery over 4 weeks.
Question Is a targeted multidomain (T-MD) intervention more effective than a standardized behavioral management intervention in adults with mild traumatic brain injury (mTBI)?
Findings In this randomized clinical trial of 162 patients, both the T-MD and behavioral management groups experienced similar improvements in mTBI symptom severity and perceived improvement in primary outcomes over 4 weeks.
Meaning The findings suggest that both T-MD and behavioral management are effective for improving global mTBI symptoms.
David B. Frank & team now report BRD4 regulates gene expression and cell differentiation of lung endodermal progenitors into epithelial cells of the lung airways:
The figure shows mutant lungs exhibit fewer and dilated airways with diminished SOX2 expression in distal airways in addition to the formation of cystic distal airway structures.

Tumor angiogenesis, the formation of new blood vessels within the tumor microenvironment, is considered a hallmark of cancer progression and represents a crucial target for therapeutic intervention.

What skills will matter when AI can do almost everything?
Here is the framing principle that governs my answer:
The skills that will matter most are not the skills AI does best. They are the skills AI cannot replicate — and the ones that become more valuable precisely because AI makes everything else cheap.
When answers are free, questions become priceless.
When content is infinite, context becomes everything.
Southwest Research Institute was part of an international team that demonstrated how complex organic molecules (COMs), key chemical precursors to life, could have been incorporated into Jupiter’s Galilean moons during their formation. The team’s findings have resulted in complementary studies published in The Planetary Science Journal and Monthly Notices of the Royal Astronomical Society, offering new insights into the potential for life in the Jovian system.
How complex organics can form Carbon-rich compounds containing oxygen, nitrogen and other elements are necessary for living matter to form. Laboratory experiments have shown that COMs can form when icy grains containing methanol or mixtures of carbondioxide and ammonia are exposed to either ultraviolet radiation or moderate heating under conditions found in protoplanetary disks. These disks of gas and dust surround newly formed stars that eventually form planets.
“By combining disk evolution with particle transport models, we could precisely quantify the radiation and thermal conditions the icy grains experienced,” said Dr. Olivier Mousis of SwRI’s solar system science and exploration division, who is lead author of one of the two studies. “Then we directly compared our simulations with other laboratory experiments that produce COMs under realistic astrophysical conditions. The results showed that COM formation is possible in both the protosolar nebula environment and Jupiter’s circumplanetary disk.”
Delve into the groundbreaking world of CRISPR gene editing – a technology rapidly reshaping medicine and offering unprecedented hope for treating previously incurable diseases. This video explores the remarkable journey from basic scientific curiosity about bacterial defense mechanisms to the first-ever personalized gene therapies being administered in Germany and beyond.
Discover how scientists uncovered CRISPR, an ancient bacterial immune system that functions as a precise molecular “cut-and-paste” tool for DNA. Learn about the astonishing speed at which this discovery transitioned from laboratory research to clinical applications, culminating in FDA approval of treatments for sickle cell disease and beta thalassemia – conditions once considered devastatingly difficult to manage.
We’ll examine the details of these revolutionary therapies, including how they work to correct genetic defects and provide lasting relief for patients. Beyond current successes, explore the exciting potential of CRISPR to address a wide range of inherited disorders, from hereditary angioedema to various cancers.
The video highlights the extraordinary case of KJ, an infant who received a custom-designed CRISPR base editing therapy to treat a rare metabolic disorder – demonstrating the feasibility of truly personalized medicine tailored to individual genetic profiles. Understand how this breakthrough compresses years of research into mere months, paving the way for treating countless other rare diseases.
Finally, look ahead to the future with the emergence of TIGR systems, an even more advanced class of gene-editing tools discovered in viruses that infect bacteria. These next-generation technologies promise enhanced precision, broader targeting capabilities, and potentially safer therapeutic applications. Join us as we unpack this complex science and reveal how fundamental research continues to unlock the secrets of life and offer hope for a healthier future.
Anthropic CEO Dario Amodei says in an interview that the company doesn’t know whether its artificial intelligence (AI) models are conscious.
In an episode of the Interesting Times podcast with New York Times columnist Ross Douthat, Amodei explained a number of technical aspects of Anthropic’s work before Douthat asked specifically whether Anthropic would believe an AI model if it said it was conscious.
“We don’t know if the models are conscious,” Amodei admitted.
“We are not even sure that we know what it would mean for a model to be conscious, or whether a model can be conscious. But we’re open to the idea that it could be.”
Anthropic releases a document called a “model card” along with its models, which puts into writing the, “capabilities, safety evaluations and responsible deployment decisions for Claude models.”
Douthat pointed out that in a model card released for Anthropic’s Claude Opus 4.6, the model, “did find occasional discomfort with the experience of being a product.”
* A “Bouncer” Made of Motion: New high-resolution microscopy and computational modeling (notably a study from late 2025) reveal that the NPC’s function is driven by this very flexibility. The disordered tails constantly rearrange themselves, creating a dynamic barrier that recognizes and ushers through specific molecules while blocking harmful enzymes or misfolded RNA.
* Scientific Breakthrough: By moving beyond static “snapshots” of the pore to observing it in motion at millisecond resolution, researchers have realized that disorder, not order, is the secret to the nuclear pore’s speed and precision.
In essence, the article highlights a paradigm shift in biology: the realization that one of life’s most complex and essential machines functions not like a rigid mechanical valve, but like a flexible, chaotic filter that uses “wiggle room” to maintain the integrity of the genetic code.
Every second, hundreds to thousands of molecules move through thousands of nuclear pores in each of your cells. A new high-definition view reveals the machine in action.
Lodi et al. create a pan-cancer single-cell atlas characterizing immune cell heterogeneity within the tumor microenvironment (TME). They identify 70 shared cell subtypes, some of which are spatially co-localized to form two distinct immune reactive TME hubs. Both hubs associate with improved checkpoint immunotherapy outcome across different cancer types.
