<strong>Fossil viruses hidden in our DNA thousands of years ago could be the cause of depression, study finds</strong>
"Ancient DNA present in humans may be linked to major psychiatric disorders like depression, researchers have said.
DNA sequences originating from ancient infections are found in the brain, with some contributing to susceptibility for conditions like schizophrenia, bipolar disorder, and depression, a study found"

<strong>Ancient genomes revealed the complex human interactions of the ancient western Tibetans</strong>
"_Outside the Tibetan Plateau, the western Tibetan Plateau populations interacted with both South and Central Asian populations at least 2,000 years ago, and the South Asian-related genetic influence, despite being very limited, was from the Indus Valley Civilization (IVC) migrants in Central Asia instead of the IVC populations from the Indus Valley._"

<strong>Mesmerising microbes: bacteria as you’ve never seen it before – in pictures</strong>
"_As a side hustle he manipulates and photographs the microbial world; his images are collected in a book, Beautiful Bacteria. Taking bacteria from substances such as wastewater, dental plaque or kimchi, Danino lets them multiply in a petri dish, adding dyes. The results are artworks differing from the digital enhancements often made in scientific photography to make images more informative._"

How to measure the Earth
"The first known calculation of the Earth’s circumference was made 2300 years ago by a man called Eratosthenes. I remember in school, how impressed I was by how accurately the Earth’s circumference was measured such long time ago. Today we’re going to take a closer look on how his calculation was made."

Backstabbing, bluffing and playing dead: has AI learned to deceive? – podcast

Thomas Willis (1621-1675) : Neurologist, Chemist, Physician
"Willis is not only credited to be the founder of neurology, but he is also seen as the father of comparative neuroanatomy, as his work, in particular Cerebri anatome and De anima brutorum, compare the human brain with that of other species in ‘search for specific human abilities in cognitive functions’ (Molnár, p. 334)."

AI deception: A survey of examples, risks, and potential solutions
"Large language models and other AI systems have already learned, from their training, the ability to deceive via techniques such as manipulation, sycophancy, and cheating the safety test. AI’s increasing capabilities at deception pose serious risks, ranging from short-term risks, such as fraud and election tampering, to long-term risks, such as losing control of AI systems."

A cubic millimeter of brain tissue may not sound like much. But considering that that tiny square contains 57,000 cells, 230 millimeters of blood vessels, and 150 million synapses, all amounting to 1,400 terabytes of data, Harvard and Google researchers have just accomplished something stupendous."

DeepMind’s AI can ‘predict how all of life’s molecules interact with each other’
"AlphaFold 3 is able to envision how the complex shapes and networks of molecules – present in every cell in the human body – are connected and how the smallest of changes in these can affect biological functions that can lead to diseases."

"...our data suggested that the Japanese population could be best modeled by admixtures of three ancestral components (hereafter K1 to K3). K1 to K3 were the highest in Okinawa, Northeast, and West, respectively (Fig. 1D and table S4). K1 (Okinawa) component maintains a relatively stable fraction of around 12% in Hondo subgroups, except for South (which is a region adjacent to Okinawa), with a higher proportion of 22%. K2 (Northeast) and K3 (West) components showed a cline from West to East."

The art of the bee
"As I set out to write a book on honey bee biology, I kept Humboldt as an aspirational model. Rather than write the typical biology text that reflected an excavation of levels of biological organization like taxonomy, biogeography, physiology, anatomy, etc., I built chapters around themes relating to honey bee impacts, behavior, and ecology."

"Infant mortality rates have plummeted over the last 50 years.
Globally, they’ve fallen by over two-thirds, from around 10% in 1974 to less than 3% today.
The study’s researchers estimate that 40% of this decline is due to vaccines."

Scientists are trying to get cows pregnant with synthetic embryos
