Thrilled to see this published today! Truly special because we made the initial discovery >15 yrs ago! We found two copies of a human gene called BC200 embedded in a human poxvirus. BC200 blurs the line between gene & transposon—both functional & mutagenic! www.science.org/doi/10.1126/... 🧵1/n

Escape of the BC200 gene to a human poxvirus reveals its persistent transposition in primates

Transposable elements mobilize within and occasionally between genomes, including from host to virus. We identified two insertions of the human BC200 noncoding RNA gene in the poxvirus molluscum conta...

Shredtools is making it easier to explore regions across a pangenome by quickly finding matching genomic regions across hundreds of genomes. The tool can identify a gene region across 476 human genomes in approximately half a second.  Read more: www.biorxiv.org/content/10.6...

Navigating the pangenome coordinate system with Shredtools

Existing notions of pangenome coordinates rely on hard-to-compute multiple sequence alignments. On the other hand, pangenome-wide exact unique matches (multi-MUMs) can be computed efficiently, and rep...

"We are probably looking at the strongest El Niño in our recorded lifetime," said #BaskinEngineering Professor of Statistics Robert Lund. This could bring sea level changes, beach erosion, damaged harbors, and inland flooding caused by heavy rainstorms. Via @ksbw.bsky.social: bit.ly/3V26CDh

Central Coast braces for heavy rain as strong El Niño approaches

Central Coast officials are preparing for a potentially wet winter as a strong El Niño is expected to bring heavy rain, flooding, and other impacts to the region.

There are a horrifying number of computer science professors that still just "solve problems" with no thoughts. People who publish papers like: "We made an algorithm that can detect human shapes from infrared data, and even works with children behind tent covers."

I've been documenting a pair of black-capped chickadees nesting in our garden as they fly back & forth every few minutes, hunting meals. An avg clutch of 6 to 8 chickadees requires 3,000 to 5,000 feedings over the ~16 days from hatching to fledging. Most popular foods: caterpillars, moths, spiders.

A collage of 16 photos of black-capped chickadees. Each photo depicts a closeup of a single chickadee with prey in their mouth, such as a caterpillar, adult moth, other winged insect, or spider. The chickadees are small songbirds with gray-white plumage and patches of black on their heads and throats.

I’ve officially resigned as Associate Editor for Frontiers in Systems Neuroscience. It used to be a reputable journal, but became a case study in how forced automation destroys academic integrity. 👇
