Alcohol’s hidden shortcut lets gut bacteria wreck the liver

Alcohol-associated liver disease is becoming a massive health and economic burden, but researchers at UC San Diego may have uncovered a new way forward. They discovered that chronic alcohol use blocks a crucial protein that normally helps keep gut bacteria from leaking into the liver, worsening damage. Restoring this protein’s function, using drugs already in development, could not only reduce liver disease but also have implications for treating alcohol addiction itself.

Wildfires are no longer a seasonal nuisance but a deadly, nationwide health crisis. Fueled by climate change, smoke is spreading farther and lingering longer, with new research warning of tens of thousands of additional deaths annually by mid-century. The health costs alone could surpass all other climate damages combined, revealing wildfire smoke as one of the most underestimated threats of our warming world.

Microplastics have been detected in human blood, brain tissue, and even bones, where they may weaken skeletal structure and accelerate cell aging. Recent studies suggest that these particles could worsen metabolic bone diseases like osteoporosis, a risk that’s especially concerning as fractures are projected to rise sharply in the coming decades.

MIT scientists have unraveled the hidden energy balance of earthquakes by recreating them in the lab. Their findings show that while only a sliver of energy goes into the shaking we feel on the surface, the overwhelming majority is released as heat—sometimes hot enough to melt surrounding rock in an instant.

A new study challenges the dream of water-rich “Hycean” planets like K2-18b, suggesting that most sub-Neptunes lose their water deep into their interiors during formation. Instead of vast oceans, these worlds likely retain only a few percent of water at the surface.

Scientists at Rutgers and collaborators have traced the invisible dark matter scaffolding of the universe using over 100,000 Lyman-alpha emitting galaxies. By studying how these galaxies clustered across three eras shortly after the Big Bang, they mapped dark matter concentrations, uncovering cosmic “fingerprints” that reveal how galaxies grow and evolve.

Astronomers have long relied on supercomputers to simulate the immense structure of the Universe, but a new tool called Effort.jl is changing that. By mimicking the behavior of complex cosmological models, this emulator delivers results with the same accuracy — and sometimes even finer detail — in just minutes on a standard laptop. The breakthrough combines neural networks with clever use of physical knowledge, cutting computation time dramatically while preserving reliability.

Why Alaska’s salmon streams are suddenly bleeding orange

September 22, 2025 0 Comments Earthquakes, Ecology, Ecosystems, Environmental Issues, Environmental Science, Forest, Global Warming, Mining

Warming Arctic permafrost is unlocking toxic metals, turning Alaska’s once-clear rivers into orange, acid-laced streams. The shift, eerily similar to mine pollution but entirely natural, threatens fish, ecosystems, and communities that depend on them—with no way to stop the process once it starts.
