Human brains light up for chimp voices in a way no one expected

Humans may carry ancient neural traces that let us recognize the voices of our primate cousins.

Humans don’t just recognize each other’s voices—our brains also light up for the calls of chimpanzees, hinting at ancient communication roots shared with our closest primate relatives. Researchers found a specialized region in the auditory cortex that reacts distinctly to chimp vocalizations, but not to those of bonobos or macaques, revealing an unexpected mix of evolutionary and acoustic influences.

Today is cloudy and cold with copious snow. This has wiped out our plans to visit a holiday market. :(

I fed the birds. I've seen a large mixed flock of sparrows and house finches, at least one female and four male cardinals, a mourning dove, and a tiny wren clinging to the bathroom window as it probed the edges for hibernating insects.

I put out water for the birds.

EDIT 12/13/25 -- I did a bit of work around the patio.

Ground Zero: Los Angeles and the Endgame of the Growth Ponzi Scheme

Los Angeles didn’t mismanage its way into crisis. It built its way here.

I disagree. If a city does not track all of its liabilities, such as the maintenance costs of roads and utilities, that is mismanagement. You can't run a budget when you don't know where your money is going. That ought to be obvious.

People have expressed interest in deep topics, so this list focuses on philosophical questions.

Is the human tendency to create groups an overall positive or a negative trait in terms of general human flourishing?

Necessary. Insofar as we know, Homo like most primates is a troop animal, evolved to live in groups rather than alone. Individuals may choose to live alone, but it is much more difficult. Of course, humans can choose to create groups that are themselves positive or negative in structure and behavior, but that's a personal choice.

Scientists find hidden rainfall pattern that could reshape farming

Where rain comes from may decide the future stability of global food production.

New research shows that crops are far more vulnerable when too much rainfall originates from land rather than the ocean. Land-sourced moisture leads to weaker, less reliable rainfall, heightening drought risk. The U.S. Midwest and East Africa are particularly exposed due to soil drying and deforestation. Protecting forests and improving land management could help stabilize rainfall and crop yields.

Allow me to point out that the Midwest used to have copious fencerows of trees and bushes, more pocket forests, and more farmhouse yards. People cut down most of those to clear a few more acres of farmland. The results have been poor across multiple areas including wildlife losses, soil erosion, worsening winds with less interruption, and of course the aforementioned droughts.

'It is the most exciting discovery in my 40-year career': Archaeologists uncover evidence that Neanderthals made fire 400,000 years ago in England

Neanderthals were the world's first innovators of fire technology, tiny specks of evidence in England suggest. Flecks of pyrite found at a more than 400,000-year-old archaeological site in Suffolk, in eastern England, push back archaeologists' evidence for controlled fire-making and suggest that key human brain developments began far earlier than previously thought.

It's exciting to see such concrete evidence.
