Cuckoo eggs are crafted to look nearly identical to those of their hosts. From background color to the placement of tiny speckles, the mimicry is so exact that it often fools even the most attentive parents.

From National Park Conservation Association
Earlier this week, Senator Mike Lee introduced an amendment that would have removed protections against selling America’s national parks. Of course, you absolutely REFUSED. And it’s working. 💪
Thanks to rapid fire pressure from advocates like you, Sen. Lee reversed his attempt to remove these national park protections from the Interior Appropriations bill. But the deal isn’t done. The Senate went on recess before voting on the bill. We need to stay vigilant. 👀 Read More…

Mediterranean dolphins have coastal and inshore ecotypes that pass each other by without interacting, like ships in the night, new study finds.
A new study challenges a long-held theory about bottlenose dolphins in the Mediterranean, revealing that they are divided by offshore and coastal ecotypes rather than being split into east and west populations.

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

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.

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.

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!

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.
