What happens when traits jump between branches of the tree of life
2hWe all must play the game of life with the cards we're dealt, so the common aphorism goes. In biology, this means organisms must compete through natural selection with the genes and anatomy they were born with. But the saying is a lie. Okay, it's not exactly a lie, but modern research suggests that the game of life is far more complicated than we had anticipated. There are opportunities to swap ca
Lost value of landfilled plastic in US
2hWith mountains of plastic waste piling up in landfills and scientists estimating that there will be more plastics by weight than fish in the ocean by 2050, the growing environmental challenge presented to the world by plastics is well understood.

US Military's Next-Gen Fighter Expected to Cost Hundreds of Millions Each
11hThe Lockheed-Martin F-35 Lightning II is the US military's current top-of-the-line fighter aircraft, but its history of cost overruns and technical issues has made it a poster child for government waste. And that may be nothing compared to the next generation of air combat technology. At a recent House Armed Services Committee hearing, Air Force Secretary Frank Kendall claims the so-called Next-G

Rapid access to polycyclic N-heteroarenes from unactivated, simple azines via a base-promoted Minisci-type annulation
12hNature Communications, Published online: 03 May 2022; doi:10.1038/s41467-022-30086-0 The functionalisation of unactivated azines has been restricted because of their intrinsic low reactivity. Here the authors show a transition-metal-free, radical relay π-extension approach to produce N-doped polycyclic aromatic compounds directly from simple azines and cyclic iodonium salts.
Dihydroquinazolinones as adaptative C(sp3) handles in arylations and alkylations via dual catalytic C–C bond-functionalization
12hNature Communications, Published online: 03 May 2022; doi:10.1038/s41467-022-29984-0 Although derived from feedstock chemicals and therefore in principle abundant, ketones are not widely used as cross-coupling partners in organic synthesis. Herein, the authors use ketone derivatives as one-electron handles for forging C(sp3) architectures via dual photo- and nickel catalysis.
CNPY4 inhibits the Hedgehog pathway by modulating membrane sterol lipids
12hNature Communications, Published online: 03 May 2022; doi:10.1038/s41467-022-30186-x Although lipids are known to affect Hedgehog (Hh) signalling, the underlying mechanisms remain unclear. Here, the authors show that Canopy4 regulates membrane sterol lipid levels, with knockout mouse embryos exhibiting digit number changes and other Hh signalling-related developmental defects.
Simultaneous stabilization of actin cytoskeleton in multiple nephron-specific cells protects the kidney from diverse injury

The representation of context in mouse hippocampus is preserved despite neural drift
12hNature Communications, Published online: 03 May 2022; doi:10.1038/s41467-022-30198-7 Recent work has shown that the tuning of hippocampal place cells changes unexpectedly across weeks, a phenomenon known as neural drift. Keinath et al. show that this drift occurs in a particular way, one which preserves the representation of context.
Ambient-pressure hydrogenation of CO2 into long-chain olefins

Here the authors report a Cu-Fe catalyst which achieves the hydrogenation of CO2 into long-chain olefins under ambient pressure via the synergy of carbide mechanism and CO inserti
High-throughput analysis of single human cells reveals the complex nature of DNA replication timing control
12hNature Communications, Published online: 03 May 2022; doi:10.1038/s41467-022-30212-y In human cell lines, DNA replication initiates primarily from a set of genomic loci shared across single cells, which fire according to a predictable but not strictly deterministic order.
