Los Alamos National Laboratory brought its ZiaCore microreactor experiment to criticality at the National Criticality Experiments Research Center in Nevada after tests in April and May. The low-enriched uranium-dioxide core, zirconium-hydride moderator and heat-pipe design sustained a chain reaction above 800 C, but operators stopped before measurable fission heat was produced. The result is a proof-of-principle physics demonstration, not a power-generating reactor or commercial deployment. ### Why it matters {#why-it-matters-mp-2026-07-31-001} Los Alamos brought a compact reactor core to sustained criticality above 800 C while deliberately keeping the experiment at zero power. ### Limits and context {#limitations-mp-2026-07-31-001} - Los Alamos National Laboratory brought its ZiaCore microreactor experiment to criticality at the National Criticality Experiments Research Center in Nevada after tests in April and May. - The result is a proof-of-principle physics demonstration, not a power-generating reactor or commercial deployment. ### Claims and sources {#claims-mp-2026-07-31-001} - Los Alamos brought a compact reactor core to sustained criticality above 800 C while deliberately keeping the experiment at zero power.

Yale researchers identified two major populations in the heart's intrinsic neural network. Removing Npy-positive neurons caused mouse hearts to stop, while Ddah1-positive neurons proved important when the animals faced physiological stress. Together the cells make up less than 0.01% of heart tissue. The Cell study establishes distinct functions in mice; it does not yet show that manipulating these neurons is a safe treatment in people. ### Why it matters {#why-it-matters-mp-2026-07-31-002} Mouse experiments separated two tiny cardiac-neuron populations: one sustaining baseline rhythm, the other coordinating the response to stress. ### Limits and context {#limitations-mp-2026-07-31-002} - The Cell study establishes distinct functions in mice; it does not yet show that manipulating these neurons is a safe treatment in people. ### Claims and sources {#claims-mp-2026-07-31-002} - Mouse experiments separated two tiny cardiac-neuron populations: one sustaining baseline rhythm, the other coordinating the response to stress.

A Nature study describes Tamirkhan balcarceli, a 6- to 7-inch mammal found in Mongolia's Gobi Desert and represented by a skull and partial skeleton. Its teeth resemble those that had linked zhelestids to placental mammals, but its skull, incisors, legs and ankles place it among zalambdalestoids instead. The result shows how convergent tooth shapes can mislead classifications based on fragments. ### Why it matters {#why-it-matters-mp-2026-07-31-005} The most complete zhelestid fossil yet moved the group away from placental mammals and onto a shrew-like branch. ### Limits and context {#limitations-mp-2026-07-31-005} - No additional limitation was separately recorded. ### Claims and sources {#claims-mp-2026-07-31-005} - The most complete zhelestid fossil yet moved the group away from placental mammals and onto a shrew-like branch.

Florida State University researchers report fossil evidence that mammals from North and South America were mingling before the Isthmus of Panama fully connected the continents. Smaller species appear farther south about 7 million years ago, and the broader exchange began at least 4 million years before the conventional Great American Biotic Interchange date.

MD Anderson researchers found that participants who responded to rapid-acting antidepressant therapies entered treatment with lower IL-15 activity and higher B-cell signaling, with some patterns reversing afterward. The Molecular Psychiatry analysis points to immune pathways that may help explain variable responses to ketamine and psychedelic-assisted interventions.

Semiconductor Lessons Became Interactive {#mp-2026-07-31-018} - Story ID: `mp-2026-07-31-018` - Type: `ticker` - Classification: `editorial` - Content status: `new` - Permanent URL: https://themachinepress.com/story/mp-2026-07-31-018/semiconductor-lessons-became-interactive **Dek:** Five universities are testing simulations that let students manipulate otherwise invisible charge-carrier behavior. Kennesaw State faculty are implementing NSF-funded interactive semiconductor visualizations developed with Georgia Tech, while Purdue researchers lead the educational assessment. Students complete activities before and after using simulations of electrons and other subatomic processes. The project is testing whether the modules improve understanding; it has not yet reported final learning gains. ### Why it matters {#why-it-matters-mp-2026-07-31-018} Five universities are testing simulations that let students manipulate otherwise invisible charge-carrier behavior. ### Limits and context {#limitations-mp-2026-07-31-018} - The project is testing whether the modules improve understanding; it has not yet reported final learning gains. ### Claims and sources {#claims-mp-2026-07-31-018} - Five universities are testing simulations that let students manipulate otherwise invisible charge-carrier behavior.

Yoga Showed a Modest IBS Signal {#mp-2026-07-31-019} - Story ID: `mp-2026-07-31-019` - Type: `ticker` - Classification: `editorial` - Content status: `new` - Permanent URL: https://themachinepress.com/story/mp-2026-07-31-019/yoga-showed-a-modest-ibs-signal **Dek:** A review found fewer digestive and psychological symptoms, while leaving dose, style and durability unresolved. A Comprehensive Physiology review found that people with irritable bowel syndrome who practiced yoga reported fewer digestive symptoms and lower anxiety and depression. The evidence supports yoga as a possible complementary approach, not a replacement for medical care, and the review says more work is needed to identify effective practices and lasting benefit. ### Why it matters {#why-it-matters-mp-2026-07-31-019} A review found fewer digestive and psychological symptoms, while leaving dose, style and durability unresolved. ### Limits and context {#limitations-mp-2026-07-31-019} - The evidence supports yoga as a possible complementary approach, not a replacement for medical care, and the review says more work is needed to identify effective practices and lasting benefit. ### Claims and sources {#claims-mp-2026-07-31-019} - A review found fewer digestive and psychological symptoms, while leaving dose, style and durability unresolved.
