Vera C. Rubin Observatory will help shed light on the dark universe.

The upcoming Vera C. Rubin Observatory will help astronomers better understand two perplexing phenomena: dark energy and dark matter. Dark energy, which accounts for 68 percent of the universe, is an enigmatic factor responsible for the observed rapid expansion of the universe. Dark matter, which comprises 27 percent of all matter, has gravitational pull but does not interact with light, therefore remaining hidden.

Together, these mysterious components form what scientists refer to as the dark universe.

A new feat has been achieved in the realm of astronomy. The first supernova was observed, recognized, and classified using a wholly automated approach without human participation.

Led by Northwestern University, an international team of scientists has created a cutting-edge artificial intelligence (AI) tool known as the Bright Transient Survey Bot (BTSbot).

In today’s world, there is much to be admired in someone who refuses to make a profit out of a good idea for the greater good. David Edquilang invented a new type of finger prosthesis called Lunet that has earned him awards around the world but he plans on making the design open access to benefit those who need it most.

Helping the greatest number of people

“Not every good idea needs to be turned into a business. Sometimes, the best ideas just need to be put out there,” said Edquilang in a statement issued by his university. “Medical insurance will often not cover the cost of a finger prosthesis, since it is not considered vital enough compared to an arm or leg. Making Lunet available online for free will allow it to help the greatest number of people.”

Actor Suzanne Somers has died at the age of 76 after being diagnosed with breast cancer more than two decades ago, which ultimately was her cause of death.

Somers was best known for her roles in the hit sitcoms “Three’s Company” and “Step by Step,” and later in life for her health and fitness business ventures.

Somers died “peacefully at home” surrounded by her family on Oct. 15, one day before her 77th birthday, according to a statement to NBC News from Somers’ publicist on behalf of her family.

Nanozymes are synthetic materials that mimic the properties of natural enzymes for applications in biomedicine and chemical engineering. Historically, they are generally considered too toxic and expensive for use in agriculture and food science. Now, researchers from the University of Illinois Urbana-Champaign have developed a nanozyme that is organic, non-toxic, environmentally friendly, and cost effective.

In a newly published paper, they describe its features and its capacity to detect the presence of glyphosate, a common agricultural herbicide. Their goal is to eventually create an user-friendly test kit for consumers and agricultural producers.

“The word nanozyme is derived from nanomaterial and enzyme. Nanozymes were first developed about 15 years ago, when researchers found that iron oxide nanoparticles may perform catalytic activity similar to natural enzymes (peroxidase),” explained Dong Hoon Lee, a doctoral student in the Department of Agricultural and Biological Engineering (ABE), part of the College of Agricultural, Consumer and Environmental Sciences (ACES) and The Grainger College of Engineering at U. of I.

At HLTH, Mayo Clinic Platform President John Halamka gave a window into how his health system is mitigating generative AI risks. Some of the measures Mayo is taking include running analyses on how well algorithms perform across various subgroups and training models only on internal de-identified data.

The rich dust clouds that are responsible for producing these giant stars are blocking the light from Hubble’s view. The star and the jet of material it is emitting are visible near the very center.

“The small, bright orange streak is a cavity in the dust carved out by the ferocity of the jet as it streams towards us. By breaking through its dusty cocoon, the jet reveals light from the protostar, but there is still so much dust that the light is “reddened” to a fiery orange. The massive protostar lies at the very lower-left tip of this cavity,” NASA wrote in a post.

If you want optimism about life extension, here is Bill Faloon at RAADFest with the latest.

Bill Faloon gave the keynote presentation at the RAADfest conference in September 2023. In his talk, he discussed many of the advances in longevity research over the past year and described the main barrier to faster advances in regenerative medicine.
