N4-Acetylcytidine enhances synthetic mRNA translation yield and fidelity - Nature
Different RNA modifications elicit different translation elongation rates for in vitro transcribed mRNAs that result in disparate translation outputs and fidelity, as shown here for N4-acetylcytidine versus the industry standard for synthetic mRNAs, N1-methyl…
Backreaction of stimulated Hawking radiation in an optical analogue - Nature
By using a fibre-optical analogue of the physics of black holes, theoretical and experimental evidence is presented for the process underpinning the generation of Hawking radiation and its backreaction onto the optical pump.
Directly probing the carrier transfer length in 2D-material transistors - Nature
Cross-sectional scanning tunnelling microscopy shows a 2 nm carrier transfer length in bismuth-contacted monolayer MoS2 transistors, defining metal-contact scaling limits for sub-10 nm 2D electronic devices.
A secreted endosymbiont protein essential for colonizing host cells - Nature
SyeA was present in the Buchnera ancestor, is secreted into the host cytoplasm, is homologous to secreted effectors of bacterial pathogens and is essential for Buchnera transmission.
Heat-triggered phospholipid flipping stabilizes plasma membrane fluidity - Nature
In rice, the P4-ATPase complex OsALA5–OsALIS2 rapidly stabilizes membrane fluidity in response to high temperature by flipping saturated phosphatidylcholines to the cytosolic leaflet of the plasma membrane.
Physicists Devise Black Hole Alternative With a ‘Mini Universe’ at Its Center - Gizmodo
A new paper tries to show how ‘gravastars’ might mimic black holes without breaking relativity.
