Scientists find a protein common to flies and people is essential for supporting the structure of axons that neurons project to make circuit connections.
In a study conducted by MIT
MIT is an acronym for the Massachusetts Institute of Technology. It is a prestigious private research university in Cambridge, Massachusetts that was founded in 1861. It is organized into five Schools: architecture and planning; engineering; humanities, arts, and social sciences; management; and science. MIT’s impact includes many scientific breakthroughs and technological advances. Their stated goal is to make a better world through education, research, and innovation.
It turns out that reports of its death were greatly exaggerated. NASA says it’s figured out a way to extend the mission of its interstellar Voyager 2 probe by another three years.
And that’s no easy feat, considering the probe has been screaming through the cosmos since 1977 and is currently more than 12 billion miles from Earth.
The probe recently switched to its backup power reserves, which were originally set aside as part of an onboard safety mechanism, according to an update by NASA’s Jet Propulsion Laboratory.
When a tapeworm sets up shop in the gut of an ant, it appears to pump antioxidants and other proteins into the creature’s bloodstream.
It’s still unclear what health effects these special proteins have, but there’s a real chance they are part of what helps infected ants stay young and yummy.
Hosting a parasitic tapeworm isn’t usually a desirable state. But the life of an infected ant known as Temnothorax nylanderi hits differently.
I don’t know about you, but any and all advancements with artificial intelligence and/or robotics makes me at least a little bit nervous.
I’ve seen a lot of movies and read even more books, and in the stories where the computers become smarter and more capable than the human beings, things never work out that well for the latter.

Ever since the release of OpenAI’s new chatbot ChatGPT in November, investors have been enamored with A.I. and its potential to revolutionize the world’s economy. Hopes for a future with increased productivity and lower costs as A.I. tools are rolled out to the masses have helped to lift markets in 2023 despite stubborn inflation, rising interest rates, and consistent recession predictions from economists. After dropping more than 30% in 2022, the tech-heavy Nasdaq Composite has recovered nearly all of its losses, gaining over 28% year to date, and the S&P 500 is now up more than 12%.
While some on Wall Street question whether stocks can continue their run of form in the second half of the year, pointing to stretched valuations in the Big Tech names and A.I. plays that have led the rebound so far, Wedbush’s top tech analyst Dan Ives argues it’s just the beginning of the “A.I. gold rush.”
“Many of the tech skeptics will point to today as a ‘1999 moment,’ à la on the verge of the dotcom bubble/collapse, given the significant move in tech valuations. We strongly disagree,” the veteran analyst wrote in a Monday research note. “While valuations in tech will be front and center, we continue to believe A.I. is driving the tech sector to a ‘1995 moment’ with a long runway of growth ahead that we have not seen since the 1990s.”
SpaceX is revolutionizing the Internet industry with its Starlink broadband satellite network. As of today, the company operates a constellation of around 4,265 Starlink satellites in Low Earth Orbit (LEO) that provide high-speed internet to over 1.5 million subscribers globally. SpaceX is launching Starlink satellites every month to continue expanding service coverage, with plans to launch a total of 12,000 satellites. Besides providing internet to homes and businesses, Starlink beams service directly to user antennas installed on vehicles in motion, like RVs, cruise ships, and aircraft.
In the early days of satellite internet, Geostationary Earth Orbit (GEO) satellites were the norm for aviation. These GEO satellites, positioned at an altitude of approximately 36,000 kilometers above the Earth’s surface, provided coverage to large regions but have limitations in terms of speed and latency – making it hard to livestream or have video calls in-flight. However, everything changed when SpaceX set its sights on LEO and launched thousands of satellites. One of the key advantages of Starlink’s satellites is the ability to provide faster internet speeds because they operate at much lower altitudes of around 550 kilometers. With traditional GEO satellites, the signal had to travel a considerable distance to reach the satellite and then make the round trip back to Earth, resulting in noticeable lag and latency average of around 600ms (milliseconds). In contrast, Starlink’s LEO satellites are positioned much closer to the planet, reducing the distance the signal travels.

The African turquoise killifish is an emerging vertebrate model organism with great potential for aging research due to its naturally short lifespan. Thus far, turquoise killifish aging omic studies using RNA-seq have examined a single organ, single sex and/or evaluated samples from non-reference strains. Here, we describe a resource dataset of ribosomal RNA depleted RNA-seq libraries generated from the brain, heart, muscle, and spleen from both sexes, as well as young and old animals, in the reference GRZ turquoise killifish strain. We provide basic quality control steps and demonstrate the utility of our dataset by performing differential gene expression and gene ontology analyses by age and sex. Importantly, we show that age has a greater impact than sex on transcriptional landscapes across probed tissues. Finally, we confirm transcription of transposable elements (TEs), which are highly abundant and increase in expression with age in brain tissue. This dataset will be a useful resource for exploring gene and TE expression as a function of both age and sex in a powerful naturally short-lived vertebrate model.
