ProteoCast predicts mutation effects across entire proteomes using sequence conservation alone. Applied to 22,000 fly protein isoforms, it correctly flags 85% of lethal mutations and identifies key sites.

Hello Bluesky!
Does Nₑ really explain mutation rate (μ) or genome size (GS) in vertebrates?
We find the apparent Nₑ–μ link in Bergeron et al. (2023) is a “back-door” path via generation time, and GS is decoupled from both Nₑ and life-history traits.

3/10 We discovered that sing different types of commonly used genome-wide markers, such as UCEs and BUSCO genes, produce fundamentally different hypotheses about shark and ray evolution! Depending on the type used, sharks are NOT necessarily their own clade!

About the museum
Natural History Museum Denmark is beautifully located in the corner of the Botanical Garden near Nørreport Station. Until October 2022 the museum also welcomed guests at the Zoological Museum at Østerbro, which is now closed to the public in order to prepare for the new museum building that will open in the Botanical Garden in a few years time.
