An AI-generated article about a murder that never happened in New Jersey has police and local news outlets in a tizzy.
During our lives, normal exposures cause DNA damage to build up. Eventually, this causes cancer and age-related diseases. Studying DNA-repairing animals could help treat these issues.
To that end, Caplan is part of a crew that posits the dark matter portion of the dark universe could very well be made up of not particles like we imagine, but instead a huge number of atom-size black holes produced during the dawn of the universe, each of which is about as massive as a typical asteroid in our own solar system. “I think all dark matter candidates are just a little bit wild,” Caplan, who is an assistant professor of physics at Illinois State University, told Space.com. “Some guesses are better than others, and primordial black holes are taken seriously. I’ll go so far as to say I think they’re popular.”
But to turn the hypothesis into fact, he says, scientists have to actually find one of these miniscule ancient voids — which brings us to this new black-hole-sun conversation. Potentially, Caplan and his co-authors say in their papers, some of those ultrasmall black holes might’ve gotten caught up in dust clouds in the midst of forming stars. Potentially, they might’ve ended up literally lodged in those eventual sparkling oceans of plasma. Potentially, they might still be there.
So, no, there is probably not a black hole in the center of our star — but there might be other stars gallivanting through space with black holes indeed wedged within their hearts.
Consciousness, “What It’s Like To Be…,” and “subjective experiences” can be explained by the Experience Recorder and Reproducer (ERR).\
We propose that a minimal primitive mind would need only to \.

Nearly 2 million Americans suffer from type 1 diabetes — a condition that causes drastic spikes or drops in sugar levels and, in turn, dizziness, nausea, and fatigue. It’s a condition that must constantly be monitored, something that a lot of diabetics find mentally exhausting.
One diabetic, Naomi, told the BBC that she couldn’t handle “the physical or mental challenges of diabetes anymore,” and struggled to monitor her blood sugar levels multiple times a day. Naomi’s struggle isn’t unique — it’s called diabetes burnout.
There’s no cure for type 1 diabetes. However, researchers at the University of Arizona have adapted a cancer immunotherapy technique that has produced promising results in treating diabetes (in mice). The researchers engineered immune cells to fight off rogue T cells (immune cells that go haywire and attack the body) that can damage the pancreas, causing type 1 diabetes.

Neutron stars are one of the most extreme and violent things in the universe. Giant atomic nuclei, only a few kilometers in diameter but as massive as stars. And they owe their existence to the death of something majestic.

Georgia Tech engineers are working to make fertilizer more sustainable—from production to productive reuse of the runoff after application—and a pair of new studies is offering promising avenues at both ends of the process.
In one paper, researchers have unraveled how nitrogen, water, carbon, and light can interact with a catalyst to produce ammonia at ambient temperature and pressure, a much less energy-intensive approach than current practice. The second paper describes a stable catalyst able to convert waste fertilizer back into nonpolluting nitrogen that could one day be used to make new fertilizer.
Significant work remains on both processes, but the senior author on the papers, Marta Hatzell, said they’re a step toward a more sustainable cycle that still meets the needs of a growing worldwide population.

The Centaur upper stage has a rich legacy of launches and will add a lunar lander to the list, with the first Vulcan launch.
The first launch of the Vulcan Centaur has been delayed by five years. Missions ahead include a lunar lander and a constellation of Kuiper satellites.
