Astronomers Discover Ultrahot Neptune around TOI-3261

The newly-discovered exoplanet orbits TOI-3261 (also known as TIC 358070912), an inactive main-sequence star located 300 parsecs (978.5 light-years) away in the constellation of Hydrus. The post Astronomers Discover Ultrahot Neptune around TOI-3261 appeared first on Sci.News: Breaking Science News.  The newly-discovered exoplanet orbits TOI-3261 (also known as TIC 358070912), an inactive main-sequence star located…

Molecular basis of mRNA delivery to the bacterial ribosome | Science

Protein synthesis begins with the formation of a ribosome-messenger RNA (mRNA) complex. In bacteria, the small ribosomal subunit (30S) is recruited to many mRNAs through base pairing with the Shine-Dalgarno (SD) sequence and RNA binding by ribosomal … Protein synthesis begins with the formation of a ribosome-messenger RNA (mRNA) complex.

Systematic in vitro evolution in Plasmodium falciparum reveals key determinants of drug resistance | Science

Surveillance of drug resistance and the discovery of novel targets—key objectives in the fight against malaria—rely on identifying resistance-conferring mutations in Plasmodium parasites. Current approaches, while successful, require laborious … Surveillance of drug resistance and the discovery of novel targets—key objectives in the fight against malaria—rely on identifying resistance-conferring mutations in Plasmodium parasites.

PIEZO-dependent mechanosensing is essential for intestinal stem cell fate decision and maintenance | Science

Stem cells perceive and respond to biochemical and physical signals to maintain homeostasis. Yet, it remains unclear how stem cells sense mechanical signals from their niche in vivo. In this work, we investigated the roles of PIEZO mechanosensitive … Stem cells perceive and respond to biochemical and physical signals to maintain homeostasis. Yet, it remains unclear…

Tlr7 drives sex differences in age- and Alzheimer’s disease–related demyelination | Science

Alzheimer’s disease (AD) and other age-related disorders associated with demyelination exhibit sex differences. In this work, we used single-nuclei transcriptomics to dissect the contributions of sex chromosomes and gonads in demyelination and AD. In a … Alzheimer’s disease (AD) and other age-related disorders associated with demyelination exhibit sex differences. In this work, we used single-nuclei transcriptomics…

Identification of a factor that accelerates substrate release from the signal recognition particle | Science

The eukaryotic signal recognition particle (SRP) cotranslationally recognizes the first hydrophobic segment of nascent secretory and membrane proteins and delivers them to a receptor at the endoplasmic reticulum (ER). How substrates are released from SRP … The eukaryotic signal recognition particle (SRP) cotranslationally recognizes the first hydrophobic segment of nascent secretory and membrane proteins and delivers…
