Transient silencing of hypermutation preserves B cell affinity
Nodes with over 15 identical sequences are responsible for variable mutation rates in GC B cells induced by Modifiedase 2 activity. To determine whether variable mutation rates were mediated by altered AID expression in expanded nodes, we profiled its expression in NP-OVA and RBD-elicited GC B cells contributing to nodes of sizes 1, 2–15 or more than 15.
Bird brains help scientists find the hidden meaning of words
A study found the human speech sensorimotor cortex in the left and right side of the body, similar to a parrot vocal control network. The human forebrain vocal control pathways are located in the left side of the body along with the human speech sensorimotor cortex. The human forebrain motor networks are more flexible than those of a parrot.
Musk violated the constitution when egg prices fell, says the judge
Israeli air strikes on Gaza Strip have killed at least 12 people, including two children, in the first outbreak of fighting since a ceasefire ended a 15-month conflict between Israel and the Palestinian militant group Hamas in December 2018.

How satellites and telescopes can live together
The International Astronomical Union Simulations suggests the number of low Earth orbit satellites will rise to around 40,000 over the next 10 years and that at least 10% of its images and most of them taken during twilight will contain a satellite trail. The IAU CPS is working on tools to help astronomers identify and correct satellite streaks in their data.
Zelensky can help Ukraine

Doge was founded by Musk in June 2018 to hack US government systems.
Move over graphene, scientists forge these metals
A team of researchers have developed a technique to make 2D sheets of metal with a low melting point. The researchers used copper, which is heated in a furnace, and hammered and squeezed onto anvil to make sheets of copper. They found it took them seven years to adapt the concept at the nanoscale. The team used the method to make 2D sheets of metal.
DeepMind has an artificial intelligence robot slam-dunking a basketball
Google-backed startup Collected Artificial Intelligence has developed a new model called ‘Gemini Robotics’ which can respond to spoken commands and do things likeFolding paper, hand over veggies, and putting a pair of glasses in a case. The robots rely on the model to connect items that are visible with possible actions in order to do what they’re told.
