In 2018, Musk wanted to take charge of OpenAI to beat Google but others opposed the move, putting Altman at the helm.
March 21 (Reuters) — Two organic compounds essential for living organisms have been found in samples retrieved from the asteroid Ryugu, buttressing the notion that some ingredients crucial for the advent of life arrived on Earth aboard rocks from space billions of years ago.
Scientists said on Tuesday they detected uracil and niacin in rocks obtained by the Japanese Space Agency’s Hayabusa2 spacecraft from two sites on Ryugu in 2019. Uracil is one of the chemical building blocks for RNA, a molecule carrying directions for building and operating living organisms. Niacin, also called Vitamin B3 or nicotinic acid, is vital for their metabolism.
The Ryugu samples, which looked like dark-gray rubble, were transported 155 million miles (250 million km) back to Earth and returned to our planet’s surface in a sealed capsule that landed in 2020 in Australia’s remote outback for analysis in Japan.
In a mind-warping milestone experiment, scientists have been able to manipulate small numbers of individual photons of light, opening doors for the development of quantum technologies. This research, published in the journal Nature Physics on March 20, describes how the researchers were able to make two photons of light interact and measure the difference between these interacting photons and a single photon.
A treatment that enables human beings to live to the age of 150 could be available within the next five to 10 years, one of the world’s most eminent plastic surgeons has claimed. Dr Steven Cohen, who specialises in complex aesthetic facial and regenerative surgery, believes the results of studies and advances in the medical sphere could soon pave the way to extend our lives.

A new class of dynamical instabilities generated by a stable photonic lattice Hamiltonian and stable dissipative pairing interaction is sensitive to wavefunction localization and allows selective excitation and entanglement of pure topological photonic edge states with minimal resources.
Gene therapy has been headline news in recent years, in part due to the rapid development of biotechnology that enables doctors to administer such treatments. Broadly, gene therapies are techniques used to treat or prevent disease by tweaking the content or expression of cells’ DNA, often by replacing faulty genes with functional ones.
The term “gene therapy” sometimes appears alongside misinformation about mRNA vaccines, which include the Pfizer and Moderna COVID-19 vaccines. These vaccines contain mRNA, a genetic cousin of DNA, that prompts cells to make the coronavirus “spike protein.” The vaccines don’t alter cells’ DNA, and after making the spike, cells break down most of the mRNA. Other COVID-19 shots include the viral vector vaccines made by AstraZeneca and Johnson & Johnson, which deliver DNA into cells to make them build spike proteins. The cells that make spike proteins, using instructions from either mRNA or viral vector vaccines, serve as target practice for the immune system, so they don’t stick around long. That’s very, very different from gene therapy, which aims to change cells’ function for the long-term.

A new high-resolution model of the CA1 region of the human hippocampus has been developed by the Institute of Biophysics of the Italian National Research Council (CNR-IBF) and University of Modena e Reggio Emilia (UNIMORE), part of the Human Brain Project.
After half a century, mathematicians succeed in finding an ‘einstein,’ a shape that forms a tiled pattern that never repeats.
Researchers in the Oregon State University College of Engineering have developed a handheld sensor that tests perspiration for cortisol and provides results in eight minutes, a key advance in monitoring a hormone whose levels are a marker for many illnesses including various cancers.
Findings were published in the journal ACS Applied Materials & Interfaces. The material and sensing mechanism in the new device could be easily engineered to detect other specific hormones, the researchers say—for example, progesterone, a key marker for women’s reproductive health and pregnancy outcomes.
“We took inspiration from the natural enzymes used in blood glucose meters sold at pharmacies,” said Larry Cheng, associate professor of electrical engineering and computer science. “In glucose meters, specific enzymes are applied to an electrode, where they can capture and react with glucose molecules to generate an electrical signal for detection. However, finding natural enzymes for cortisol detection is not straightforward, and natural enzymes are prone to instability and have a short lifespan.”
