This Cheery Little Butterflyfish Has A Big Job. He’s Charged With Snacking On Tiny Nuisance Aiptasia

What we all need to understand about AI in a nutshell:

There’s an algorithm that can reliably predict, from aggregate facebook posts, the onset of a manic episode in a person suffering from bipolar disorder – more reliably even, than a trained psychotherapist, who only has access to the information a patient provides them in therapy sessions. 

“Won’t technology like that help people with bipolar disorder?”

Theoretically, it could. But this algorithm wasn’t designed to help people with bipolar disorder.

This algorithm was designed to sell plane tickets to Las Vegas.

The real difference between us and chimpanzees is the mysterious glue that enables millions of humans to cooperate effectively. This mysterious glue is made of stories, not genes. We cooperate effectively with strangers because we believe in things like gods, nations, money and human rights. Yet none of these things exists outside the stories that people invent and tell one another. There are no gods in the universe, no nations, no money and no human rights—except in the common imagination of human beings.

X-ray binary (black hole devouring a star)

X-ray binaries are a class of binary stars that are luminous in X-rays. The X-rays are produced by matter falling from one component, called the donor (usually a relatively normal star), to the other component, called the accretor, which is very compact: a neutron star or black hole. The infalling matter releases gravitational potential energy, up to several tenths of its rest mass, as X-rays. (Hydrogen fusion releases only about 0.7 percent of rest mass.) The lifetime and the mass-transfer rate in an X-ray binary depends on the evolutionary status of the donor star, the mass ratio between the stellar components, and their orbital separation.

An estimated 1041 positrons escape per second from a typical low-mass X-ray binary.

Today's Men Carry Traces of Ancient Wars in Their Genes

Modern men’s genes suggest that something peculiar happened 5,000 to 7,000 years ago: Most of the male population across Asia, Europe and Africa seems to have died off, leaving behind just one man for every 17 women.

This so-called population “bottleneck” was first proposed in 2015, and since then, researchers have been trying to figure out what could’ve caused it. One hypothesis held that the drop-off in the male population occurred due to ecological or climatic factors that mainly affected male offspring, while another idea suggested that the die-off happened because some males had more power in society, and thus produced more children.

Now, a new paper, published May 25 in the journal Nature Communications, offers yet another explanation: People living in patrilineal clans (consisting of males from the same descent) might have fought with each other, wiping out entire male lineages at a time. Read more.
