Human ancestors may have almost died out after ancient population crash

Posted by in categories: biotech/medical, existential risks

Almost 99% of all human ancestors may have been wiped out around 930,000 years ago, a new paper has claimed.

The new research, published in the journal Science, used DNA from living people to suggest that humans went through a bottleneck, an event where populations shrink drastically. The paper estimates that as few as 1,300 humans were left for a period of around 120,000 years.

While the exact causes aren’t certain, the near-extinction has been blamed on Africa’s climate getting much colder and drier.

OpenAI unveils newest AI model, GPT-4o

Posted by in category: robotics/AI

ChatGPT is about to become a lot more useful.

OpenAI on Monday announced its latest artificial intelligence large language model that it says will make ChatGPT smarter and easier to use.

The new model, called GPT-4o, is an update from the company’s previous GPT-4 model, which launched just over a year ago. The model will be available to unpaid customers, meaning anyone will have access to OpenAI’s most advanced technology through ChatGPT.

Researchers publish largest-ever dataset of neural connections

Posted by in categories: biotech/medical, information science, robotics/AI

Scientists have published the most detailed data set to date on the neural connections of the brain, which was obtained from a cubic millimeter of tissue sample.


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.

Led by Jeff Lichtman, the Jeremy R. Knowles Professor of Molecular and Cellular Biology and newly appointed dean of science, the Harvard team helped create the largest 3D brain reconstruction to date, showing in vivid detail each cell and its web of connections in a piece of temporal cortex about half the size of a rice grain.
