Two eggs fertilized by two sperm coincided in a uterus and, instead of giving rise to two sisters, they fused to form a single person: Karen Keegan. When she was 52 years old, this woman from Boston suffered very serious kidney failure, but luckily she had three children willing to donate a kidney to her. The doctors did genetic tests to see which offspring was most compatible and they got a major surprise: the test said that two of them were not her children. The reality was even more astonishing: Karen Keegan had two different DNA sequences, two genomes, depending on the cell you looked at. Biologist Alfonso Martínez Arias maintains that this chimeric woman is conclusive proof that DNA does not define a person’s identity.

The most inspiring science book of all time is The Selfish Gene, according to a survey carried out by the Royal Society of the United Kingdom. In this famous work from 1976, British biologist Richard Dawkins defended that the DNA molecule uses the human being as a mere envelope in order to be transmitted to the next generation and become immortal. “We are survival machines, robot vehicles blindly programmed to preserve the selfish molecules known as genes,” Dawkins stated. Almost half a century later, Martínez Arias refutes this perspective of the selfish gene and proposes a much more romantic alternative: the altruistic cell. “An organism is the work of cells. Genes merely provide materials for their work,” he says in The Master Builder, a fascinating and provocative book from the London publisher Basic Books that will also be published in Spanish this year.

Martínez Arias, 68, argues that the DNA sequence of an individual is not an instruction manual or a construction plan for their body, but a box of tools and materials for the true architect of life: the cell. The Madrid-born biologist argues that there is nothing in the DNA molecule that explains why the heart is located on the left, why there are five fingers on the hand or why twin brothers have different fingerprints. Cells are what “control time and space,” he proclaims. They are the ones who know where right and left are, and where exactly a person’s foot or an elephant’s trunk should end.

Elon Musk has given an update with an outline for Tesla’s upcoming Full Self-Driving (FSD) software updates.

With FSD v12 and the upcoming launch of Tesla’s dedicated Robotaxi, there’s a lot of excitement around Tesla’s self-driving effort.

Musk is again in the too-familiar position of predicting that the automaker is close to releasing a true self-driving system, but the path to get there is still far from clear.

Two OpenAI employees who worked on safety and governance recently resigned from the company behind ChatGPT.

Daniel Kokotajlo left last month and William Saunders departed OpenAI in February. The timing of their departures was confirmed by two people familiar with the situation. The people asked to remain anonymous in order to discuss the departures, but their identities are known to Business Insider.

A new paper suggests diminishing returns from larger and larger generative AI models. Dr Mike Pound discusses.

Microsoft has given a customized version of ChatGPT-4 to United States intelligence agencies, and it has one big differentiating feature.

EA CEO Andrew Wilson says developers have a ‘real hunger’ for generative AI, so expect the next Battlefield to include some form of AI.

Inspired by the tetromino shapes in the classic video game Tetris, researchers in the US have designed a simple radiation detector that can monitor radioactive sources both safely and efficiently. Created by Mingda Li and colleagues at the Massachusetts Institute of Technology, the device employs a machine learning algorithm to process data, allowing it to build up accurate maps of sources using just four detector pixels.

Wherever there is a risk of radioactive materials leaking into the environment, it is critical for site managers to map out radiation sources as accurately as possible.

The Church of Jesus Christ of Latter-day Saints published some statements about artificial intelligence (AI). The Church is by far the largest Mormon denomination – and that of which I’m a member. Its statements influence the perspectives and actions of millions of Mormons worldwide. Friends called the Church’s statements to my attention, asking for my thoughts.
