The aging human brain is fascinating, because in some ways, it improves with age – but we generally hear more about how it declines. That’s understandable!
After all, there are a host of neurodegenerative diseases that none of us want to end up with.
Previous research has shown that some of the seemingly inevitable declines in brain health, often seen in 70-and 80-year old brains, start in midlife.
Scientists just reversed a type of aging damage that was called permanent for 40 years. Revel Pharmaceuticals used an AI-designed enzyme called CMLase to strip decades of glycation and AGEs out of human tissue, taking 75-year-old skin below the level of 31-year-old skin on a key aging marker. Aging reversal, in real human tissue, this month.
And it landed days after Matt Kaeberlein, one of the most respected longevity scientists alive, called reversing biological aging a \.
Graphite, the carbon center of your humble #2 pencil, is also an essential component in technologies such as batteries, smartphones, laptops, and industrial power equipment. Today, nearly all of this critical mineral has to be mined and processed and, in the United States, imported.
But now, researchers at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab), UC Berkeley, and Estonia’s National Institute of Chemical Physics and Biophysics have shown a promising way to convert waste carbon pulled from the air into graphite, opening up a potential alternative to mining. The work was published recently in the journal Nature Communications.
Researchers built a custom microscope setup to watch a process known as molten-salt electrolysis, which uses electricity and hot liquid salts to turn carbon dioxide into solid carbon. For the first time, researchers were able to watch the process in real time inside the corrosive, 500-degree-Celsius molten salts while the system was running.
A total of 134 patients were included, with a median follow-up of 29.8 months. Median OS was 35 months (95% CI: 28.8–43), and median PFS was 20.9 months (95% CI: 14.5–27.4). Grade 2 tumors demonstrated significantly improved outcomes compared to grade 3 tumors (median OS 94.5 vs. 29.8 months; median PFS 50.6 vs. 15.3 months). Among grade 3 tumors, sequential radiation and chemotherapy yielded a median OS of 29.8 months versus 29.8 months with concurrent chemoradiation followed by chemotherapy (p = 0.17); median PFS was 22.2 months versus.
IDH-wt gliomas with grade 2–3 histology have heterogeneous outcomes. Grade 3 tumors show survival comparable to molecular glioblastoma, while a subset of grade 2 tumors exhibit prolonged survival. Concurrent chemoradiation did not confer a survival advantage over sequential therapy in grade 3 tumors, supporting reevaluation of treatment intensity in selected patients.
Engram cells are formed during learning and store memory information. However, little is known about the modulation of engram cells on time-dependent memory flexibility. Employing a male mouse model, we demonstrated that a temporal factor dictates the memory state, driving either pattern separation or pattern completion. Reengagement of engram cells in the dentate gyrus (DG) during memory retrieval in altered contexts was higher during pattern separation than during pattern completion, concomitant with a time-dependent reduction in synaptic transmission. Specific activation of DG engrams promoted pattern separation, whereas their inhibition accelerated pattern completion.
Artificial intelligence is not simply another chapter in the history of technology. It is becoming the cognitive infrastructure of modern civilization. Like electricity transformed the Industrial Age and the Internet transformed the Information Age, AI will define the Intelligence Age. Its true power will not come from replacing people, but from amplifying human ingenuity through the convergence of computing, cybersecurity, robotics, quantum science, biotechnology, and human creativity. The future will belong to societies that innovate boldly, secure wisely, govern responsibly, and never lose sight of the fact that technology should ultimately serve humanity—not the other way around.
