Have you ever worked with samples containing DNA from prokaryotes and eukaryotes (e.g. host and microbe)? If so, I recently wrote a software program that can separate out bacterial/archaeal sequences from eukaryotic ones: bmcgenomics.biomedcentral.com/articles/10.11…

Timeline of World War II

The Eastern Airlines 401 crash (the L-1011 Tristar in the Everglades in 1972) could be compared, somehow, to the famous Benjamin Franklin quote: "For want of a nail the shoe is lost, for want of a shoe the horse is lost, for want of a horse the rider is lost" This accident is featured on the latest video from the excellent YouTube Channel "Green Dot Aviation", which thoroughly analyzes the accident, which, coupled with some similar events (Tenerife, the UAL DC-8 in Portland) became one of the case studies that led to the foundation of CRM - Crew Resource Management (Will add link to video in the comments)

Inflation is “the most regressive tax that anyone in Washington could come up with,” Kevin Warsh has said. “If you were trying to do the most harm to the least well off among us, inflation would be the way to do it."

The math on this black hole should mass-humble every physicist who thinks we understand gravity. M87's central black hole is 6.5 billion times the mass of our Sun. It's 38 billion kilometers across. It spins at 80% of the theoretical maximum speed allowed by physics. And it's firing a plasma beam at near light speed that stretches 5,000 light-years into space. To put 5,000 light-years in perspective: if you started driving at highway speed when the Egyptian pyramids were built, you'd have covered roughly 0.0005 light-years by now. This beam covers ten million times that distance. The plasma travels in a spiral along a coiled magnetic field. Hubble watched it for 13 years just to confirm the motion pattern. And the beam isn't just decorating empty space. Stars near its path explode twice as often as stars elsewhere in the galaxy. Nobody knows why. The lead researcher at Stanford said they don't understand the mechanism at all. The black hole eats roughly 90 Earth masses of material per day. The energy output from that feeding process matches the power of the jet itself, somewhere between 10^33 and 10^37 joules per second. The upper end of that range is a number so large it has no human analogy. Your brain runs on 20 watts. This thing outputs more energy per second than every star in the Milky Way combined. And we photographed it with a telescope in 2019.

In 4.4 billion years, the constellations we use for navigation will be gone. The sun will be thrown into a new orbit, and the Milky Way will be swallowed by Andromeda. This is what the end of a 13-billion-year legacy looks like.

@DailyTurkic en.wikipedia.org/wiki/Chu_shogi I know of a 12x12 historical version of Japan's chess-like Shogi game, up to a crazy 36x36 version. Features pieces like the "drunk elephant" and "flying chariot".

Universities are meant to model openness and critical thinking. Yet many academics remain silent about injustice within their own institutions. This new article from ecrLife examines two entrenched mechanisms that may be helping sustain that culture. ecrlife.org/structural-pre…

@usgraphics Pittsburgh reigns supreme as the most beautiful city in the United States.

To do this research, we relied on two young endosymbiont genomes recently acquired by the long-tailed mealybug (Pseudococcus longispinus) and combined transcriptomics, ribosome profiling, and mass spectrometry proteomics to follow pseudogenes from RNA to ribosome to protein.

We find a possible role for tmRNA-mediated ribosome rescue as a short-term mechanism to clear aberrant peptides + recycle ribosomes stalled on pseudogenes. Over time, pseudogenes lose promoter and ribosome-binding signals, reducing their transcription and translation.

Happy to share a preprint—the last chapter of my dissertation with the McCutcheon Lab — on what happens when bacterial endosymbionts accumulate huge numbers of pseudogenes during early genome reduction. biorxiv.org/content/10.648…

One thing I learned with this account was that as time goes by, some accidents, no matter how tragic, simply fade from general memory. This is one of them, so surprised that a few days ago, someone uploaded this animation depicting the final moments of this avoidable crash

🚨: You are looking at NOBLE PRIZE WINNING work. This is timelapse of stars orbiting the supermassive black hole that lies at the heart of the Milky Way over a period of nearly 20 years.

holy sh*t. this is hands down the coolest website i have ever found in my life. it's a live feed of the freaking Hubble Telescope AND James Webb Space Telescope. and the resolution is honestly so incredible i didn't think it was real. unbelievable. spacetelescopelive.org

Making “classroom neutrality” a university policy is a welcome development. Especially significant is Garber’s explicit admission that activist faculty have degraded intellectual life on campus. Other university administrations should follow suit and acknowledge their mistakes.
