Sean Carroll, a physicist at Johns Hopkins University, spoke at the Bell House in Brooklyn, New York, in an event presented by New York City’s Secret Science Club. He talked about quantum field theory, which is now considered the definitive explanation of what reality is made of. So, pretty important stuff.

His new book The Biggest Ideas in the Universe: Quanta and Fields was released this week. It’s the second in a three-book series in which he goes through the important ideas of Physics for non-academics, but actually using and carefully explaining the equations that physicists use.

The planet is only a little smaller than Earth, but is 40 light years away.

A former Facebook director is praising AI’s prowess, likening the technology’s co-pilot coding ability to a religious experience.

In a Thursday post on X, Aditya Agarwal attempted to describe the feeling of coding alongside a large language model co-pilot.

Some think the reason fundamental scientific revolutions are so rare is because of groupthink. It’s not; it’s hard to mess with success.

Prime editing, a mightier version of CRISPR/Cas9 technology, has been part of rigorous research and development in recent years. Now, U.S. regulators have greenlit the first-ever clinical trial for this technology.

Massachusetts-based Prime Medicine received the go-ahead from the U.S. Food and Drug Administration (FDA) after preclinical data showed that its candidate was able to correct mutations in chronic granulomatous disease (CGD).

CGD is a rare condition and affects around one in 200,000 people worldwide. It is caused by mutations in any of the six genes that code for the molecule nicotinamide adenine dinucleotide phosphate (NADPH), which is responsible for carrying electrons within cells. White blood cells called phagocytes don’t function properly, and as a result, they fail to protect the body from bacterial and fungal infections.

The ability to genetically modify haematopoietic stem cells would allow the durable treatment of a diverse range of genetic disorders but gene delivery to the bone marrow has not been achieved. Here lipid nanoparticles that target and deliver mRNA to 14 unique cells within the bone marrow are presented.

The human genome consists of around 3 billion base pairs and humans are all 99.6% identical in their genetic makeup. That small 0.4% accounts for any difference between one person and another. Specific combinations of mutations in those base pairs hold important clues about the causes of complex health issues, including heart disease and neurodegenerative diseases like schizophrenia.

Although this is still an emerging area of research, a new study has announced a leap. Researchers from the Center for Neuromorphic Engineering at the Korea Institute of Science and Technology (KIST) have implemented an integrated hardware system consisting of artificial neurons and synaptic devices using hexagonal boron nitride (hBN) material.

They aimed to construct building blocks of neuron-synapse-neuron structures that can be stacked to develop large-scale artificial neural networks.

Autonomous and AI-enabled systems increasingly rely on optical and radio frequency sensors and significant computer power. They face growing vulnerabilities from directed-energy laser and microwave weapons.

In May the U.S. secretary of the Air Force flew in an F-16 that engaged in a mock dogfight over the California desert while controlled by artificial intelligence. Carmakers from San Francisco to Boston are jousting to deliver driverless cars. In Norway a crewless cargo ship carries fertilizer from port to port. On the land, sea and in the air, we face the coming of such autonomous platforms—some envisioned to benefit humanity, and others meant for destruction—available to everyone, to governments, businesses and criminals.
