Researchers used a nanoindenter to poke #leaves and found that triggered #cells soften instantly, snapping the trap shut like a rubber popper toy flipping inside-out.

#Collagen, the human body’s most abundant #protein, is liquid-like inside #cells
New study overturns a 60-year-old assumption about the body's primary structural building block, opening new avenues for treating fibrosis and cancer.

How our #cells evolved: #Genome analysis rewrites the origin of the first #eukaryotes
Using the MareNostrum supercomputer, researchers at BSC-CNS and IRB Barcelona discover that the first complex cells emerged from a gradual, millions-year alliance involving giant #viruses and multiple bacterial groups
How our cells evolved: Genome analysis rewrites the origin of the first eukaryotes
Published in Nature, the team led by Dr. Toni Gabaldón used the MareNostrum supercomputer to reconstruct the genetic origin of the last common ancestor of all eukaryotes—the cellular lineage to which animals, plants, fungi, and protists belong. The study challenges the idea that cellular complexity emerged from a single evolutionary encounter, pointing instead to a gradual process of interactions among different microorganisms that lasted for millions of years. The findings, which culminate more than five years of computational work, identify contributions from several bacteria in addition to the one that gave rise to mitochondria, and suggest that giant viruses may have acted as vehicles for gene transfer.
💁🏻♀️ TIL: 🐈🧬 A team at #Stanford identified the ancient genetic mutation that makes orange #cats orange – a tiny deletion on the X chromosome that flips a gene on in pigment #cells, blocking dark pigment and turning fur orange.
The mechanism is unlike anything seen in any other #mammal, which explains why about 80% of orange cats are male: the mutation is on the X chromosome. The #study traces the #mutation back to #medieval times, when calico cats appeared in 12th-century #paintings.

💁🏻♀️ ICYMI: 🧬🩹 Every minute, the #DNA inside our #cells is under attack. Most fixes are simple, but sometimes both strands of DNA snap, an injury called a "double-strand break."
Left unrepaired, this damage can lead to cell death or genetic mutations that drive #cancer. To fix it accurately, specialized repair proteins use a process called homologous recombination.
