Why some ant colonies get tricked into killing their own queens
NPR reported
Biologist E.O. Wilson once wrote that “ants are the most warlike of all animals,” noting that clashes between ant colonies dwarfed the human battles at Waterloo and Gettysburg. But sometimes ant colonies get conquered not by outright warfare, but by stealth and deceit.
In fact, sometimes the members of an ant colony can get tricked into murdering their own precious queen

New Research Shows Redwoods Stand Strong Amid Wildfires—But Management Matters
Save the Redwoods News Release
Cal Poly Humboldt study in partnership with Save the Redwoods League reveals how second-growth forests respond to modern wildfires and what managers can do to protect them.
California’s coast redwoods have stood for centuries, weathering a changing climate, logging, and time itself. But in an era of hotter, more frequent wildfires, their future resilience depends on how we care for them, according to new research published in Forest Ecology and Management.
The study sought to understand the effects of wildfire on coast redwoods—the tallest trees in the world. Results revealed that redwoods in second-growth forests largely survived extreme wildfires in 2020 and quickly resprouted from their trunks and bases. Researchers also discovered that forest structure—how dense the trees are and which species are present—strongly influences fire severity, highlighting the importance of management efforts such as thinning, reducing fuel loads, and encouraging fire-resistant species.

Wild chimps consume more alcohol than anyone expected
ScienceDaily reported
Chimpanzees naturally ingest surprising amounts of alcohol from ripe, fermenting fruit. Careful measurements show that their typical fruit diet can equal one to two human drinks each day. This supports the idea that alcohol exposure is not a modern human invention but an ancient primate habit. The work strengthens the “drunken monkey” hypothesis and opens new questions about how animals use ethanol cues in their environment.

Our solar system is moving faster than expected
EureakAlert! reported
How fast and in which direction is our solar system moving through the universe? This seemingly simple question is one of the key tests of our cosmological understanding. A research team led by astrophysicist Lukas Böhme at Bielefeld University has now found new answers, ones that challenge the established standard model of cosmology. The study’s findings have just been published in the journal Physical Review Letters.
“Our analysis shows that the solar system is moving more than three times faster than current models predict,” says lead author Lukas Böhme. “This result clearly contradicts expectations based on standard cosmology and forces us to reconsider our previous assumptions.”Read more Our solar system is moving faster than expected | EurekAlert!

Coho salmon are making a comeback in the Russian River for the first time in 30 years
From the Office of the Governor
Governor Gavin Newsom today celebrated a monumental achievement for California as salmon are making a comeback in Northern California. This summer, several juvenile coho salmon were spotted in the Russian River’s upper basin – a first in more than 30 years. California has recently marked significant progress in its comprehensive strategy to help these threatened and endangered salmon species recover — while the Trump administration has rolled back protections and turned its back on preserving endangered species and the precious ecosystems we all rely on.

Annual Wild Mushroom Advisory in East Bay Regional Parks
Due to this year’s early rainy season, wild mushrooms are popping up in great numbers throughout East Bay Regional Parks. Mushrooms are an ecologically important part of the parklands and can look beautiful—but some of them contain dangerous toxins. The death cap (Amanita phalloides) and western destroying angel (Amanita ocreata) are two of the world’s most toxic mushrooms, and both can be found in Regional Parks during the rainy season.
Read more Annual Wild Mushroom Advisory in East Bay Regional Parks | East Bay Parks
The death cap and western destroying angel mushrooms contain amatoxins, molecules that are deadly to many animals. Symptoms may not appear until up to 12 hours after consumption, beginning as severe gastrointestinal distress and progressing to liver and kidney failure if treatment is not sought immediately.
Both of these mushrooms can be lethal to humans and pets if consumed. Pet owners should contact a veterinarian immediately if they suspect their pet may have eaten a toxic mushroom. They are mainly associated with oak trees and can be found growing anywhere oak roots are present. Collecting any mushrooms in East Bay Regional Parks is not allowed.
