Impacts shaped Earth’s first continents

Heat from large impacts may have melted most of Earth’s earliest crust

Lariat RNA debranching prevents harmful siRNA burst in plants

Lariat RNAs are formed from introns during pre–messenger RNA splicing, after which they are degraded by the debranching enzyme DBR1. Impairment of DBR1 leads to developmental arrest, yet the mechanism...

Nodeless superconducting gap and electron-boson coupling in (La,Pr,Sm) ₃ Ni ₂ O ₇ films

The discovery of superconductivity in Ruddlesden-Popper bilayer nickelate films under ambient pressure provides an opportunity to directly investigate electronic energy scales of the superconducting s...

Reversible suppression of autophagy in a mouse model reveals neuronal resilience

Impairments in intracellular quality-control mechanisms, including autophagy, affect neuronal integrity and function. Despite numerous studies aimed at slowing neuronal deterioration, it remains uncle...

Words vs. worlds

As building bigger and better chatbots gets harder, AI researchers turn to agents that learn in simulated worlds

An ancient mystery: missing males

Fossil proteins show 20 members of an extinct human species found in a South African cave were female

EU Omnibus proposal increases pesticide risks

More efficient environmental risk assessment and stronger protection are achievable

Antibiotics stimulate protein transfer to persister cells

The exchange of biological matter between bacterial cells drives adaptation and evolution. However, whether bacteria can exchange functional proteins remains unclear. In this work, we found that antib...

Cryo–electron microscopy structures of human cone visual pigments

Human trichromatic color vision relies on three cone opsins [long-, middle-, and short-wavelength-sensitive opsins (LWS-, MWS-, and SWS-opsins, respectively)], whereas scotopic rod vision is mediated...
