Nutritional deprivation triggers a switch from a saprotrophic to predatory lifestyle in soil-dwelling nematode-trapping fungi (NTF). In particular, the NTF Arthrobotrys oligospora secretes food and sex cues to lure nematodes to its mycelium and is triggered to develop specialized trapping devices. Captured nematodes are then invaded and digested by the fungus, thus serving as a food source. In this study, we examined the transcriptomic response of A. oligospora across the stages of sensing, trap development, and digestion upon exposure to the model nematode Caenorhabditis elegans. A. oligospora enacts a dynamic transcriptomic response, especially of protein secretion–related genes, in the presence of prey. Two-thirds of the predicted secretome of A. oligospora was up-regulated in the presence of C. elegans at all time points examined, and among these secreted proteins, 38.5% are predicte.
In 1991, the University of Utah Fly’s Eye experiment detected the highest-energy cosmic ray ever observed. Later dubbed the Oh-My-God particle, the cosmic ray’s energy shocked astrophysicists. Nothing in our galaxy had the power to produce it, and the particle had more energy than was theoretically possible for cosmic rays traveling to Earth from other galaxies. Simply put, the particle should not exist.
The Telescope Array has since observed more than 30 ultra-high-energy cosmic rays, though none approaching the Oh-My-God-level energy. No observations have yet revealed their origin or how they are able to travel to Earth.

That’s high praise in a country where EVs rule the market. With this being said, the Model 3 is still not perfect.
British Architecture firm Foster + Partners has won an international competition to design a new terminal for Abha Airport in Saudi Arabia.
Some OpenAI clients are seeking alternatives since the drama unfolded with the ousting of CEO Sam Altman.
Craig Walker is the founder and CEO of cloud communications software company Dialpad, which was most recently valued at $2.2 billion.
As the dust still settles on OpenAI’s latest drama, a letter has surfaced from several staff researchers citing concerns about an AI superintelligence model under development that could potentially pose a threat to humanity, according to those close to the source. The previously undisclosed letter is understood to be the real reason behind why Sam Altman was fired from the company.
The model, known internally as Project Q*, could represent a major breakthrough in the company’s pursuit of artificial general intelligence (AGI) – a highly autonomous branch of AI superintelligence capable of cumulative learning and outperforming humans in most tasks. And you were worried about ChatGPT taking all our jobs?
With Sam Altman now firmly back at the company and a new OpenAI board in place, here are all of the details of Project Q*, as well as the potential implications of AGI in the bigger picture.

Researchers in Texas have developed a method to keep a brain alive and functioning for several hours without being connected to the body — a truly weird scientific experiment that recalls the head in jars bit in the iconic cartoon “Futurama.”
A team led by the University of Texas Southwestern Medical Center in Dallas took two pigs and severed connections between their heads and bodies, instead hooking the brains up to a device they call the extracorporeal pulsatile circulatory control (EPCC), which they detailed in a paper published in the journal Scientific Reports. The machine keeps blood pumping through the brain, mimicking the natural flow when it’s connected to the rest of the body.
