Geologists Solve a 620-Mile Mystery: The Forgotten History of the Denali Fault’s

Posted by in category: mathematics

New research on the Denali Fault reveals three geologic sites were once united in a suture zone, marking the integration of Wrangellia into North America. The study uses inverted metamorphism and monazite analysis to trace tectonic history.

New research has revealed that three sites along a 620-mile segment of Alaska’s Denali Fault were once part of a smaller, unified geologic structure, marking the final connection of two ancient land masses. Over millions of years, this structure was torn apart by tectonic forces.

The study, led by Sean Regan, an associate professor at the University of Alaska Fairbanks (UAF) Geophysical Institute and the UAF College of Natural Science and Mathematics, is featured on the cover of the December issue of Geology, the journal of the Geological Society of America.

Antihyperhelium-4: How scientists got a glimpse into the first seconds of the Universe

Posted by in categories: cosmology, particle physics

Scientists at the Large Hadron Collider (CERN), the world’s most powerful elementary particle booster, have discovered the heaviest form of antimatter ever observed. This discovery is as significant as previous achievements at CERN, in particular the discovery of the Higgs boson and studies of B-meson decay.

The ALICE (A Large Ion Collider Experiment) has discovered an antimatter particle, antihyperhelium-4. It is the “evil twin” of another exotic particle, hyperhelium-4. This form of antimatter consists of two antiprotons, an antineutron, and an unstable antilambda particle, which in turn contains quarks.

“WWI Fighter Plane Hack” Inspires Breakthrough in Cancer Treatment

Posted by in categories: bioengineering, biotech/medical, cybercrime/malcode, military

Researchers at the University of Massachusetts Amherst have developed an innovative technology inspired by the synchronization mechanism of WWI fighter aircraft, which coordinated machine gun fire with propeller movement. This breakthrough allows precise, real-time control of the pH in a cell’s environment to influence its behavior. Detailed in Nano Letters, the study opens exciting possibilities for developing new cancer and heart disease therapies and advancing the field of tissue engineering.

“Every cell is responsive to pH,” explains Jinglei Ping, associate professor of mechanical and industrial engineering at UMass Amherst and corresponding author of the study. “The behavior and functions of cells are impacted heavily by pH. Some cells lose viability when the pH has a certain level and for some cells, the pH can change their physiological properties.” Previous work has demonstrated that changes of pH as small as 0.1 pH units can have physiologically significant effects on cells.

Quantum Computing 2025 — Is it Turning the Corner?

Posted by in categories: computing, quantum physics

It’s time to stop doubting quantum information technology.

Are we there yet? No. Not by a long shot. But the progress on a number of key challenges, the sheer number of organizations fighting to succeed (and make a buck), the no-turning-back public investment, and nasty international rivalry are all good guarantors.

It feels like quantum computing is turning an important corner, maybe not the corner leading to the home stretch, but likely the corner beyond the turning back point. We now have quantum computers able to perform tasks beyond the reach of classical systems. Google’s latest break-through benchmark demonstrated that. These aren’t error corrected machines yet, but progress in error correction is one of 2024’s highlights.

Brain-wide cell-type-specific transcriptomic signatures of healthy ageing in mice

Posted by in categories: biotech/medical, food, life extension, neuroscience

Sensitive cells: Scientists discovered dozens of specific cell types, mostly glial cells, known as brain support cells, that underwent significant gene expression changes with age. Those strongly affected included microglia and border-associated macrophages, oligodendrocytes, tanycytes, and ependymal cells.

Inflammation and neuron protection: In aging brains, genes associated with inflammation increased in activity while those related to neuronal structure and function decreased.

Aging hot spot: Scientists discovered a specific hot spot combining both the decrease in neuronal function and the increase in inflammation in the hypothalamus. The most significant gene expression changes were found in cell types near the third ventricle of the hypothalamus, including tanycytes, ependymal cells, and neurons known for their role in food intake, energy homeostasis, metabolism, and how our bodies use nutrients. This points to a possible connection between diet, lifestyle factors, brain aging, and changes that can influence our susceptibility to age-related brain disorders.
