Rapamycin-sensitive mechanisms confine the growth of fission yeast below the temperatures detrimental to cell physiology

This study shows that rapamycin enables fission yeast to grow at high temperatures by inhibiting TORC1, suggesting that TORC1 normally restricts high-temperature growth rather than promoting it.

Seasonal gene-expression signatures of delayed fertilization in Fagaceae

This study identifies seasonal gene-expression differences between one- and two-year fruiting Fagaceae species, linking delayed fertilization to cold stress and reproductive barrier mechanisms.

Somatic mutation rates scale with time not growth rate in long-lived tropical trees

This study finds that somatic mutation rates in tropical trees scale with time, not growth rate, showing a constant mutation rate per year across species with different growth rates.

Autotoxin-mediated voluntary triage in starved yeast community

The paper shows yeast communities use autotoxins to selectively eliminate non-tagged cells during starvation, enabling survival through voluntary triage.

Biosynthesis of β-(1->5)-Galactofuranosyl Chains of Fungal-Type and O-Mannose-Type Galactomannans within the Invasive Pathogen Aspergillus fumigatus

This study identifies GfsA and GfsC as enzymes responsible for biosynthesis of β-(1→5)-galactofuranosyl residues in Aspergillus fumigatus, showing their roles in cell growth and virulence.

Development of the Brief Personal Values Inventory for sense of values in the Japanese general population

The paper develops a shorter questionnaire, BPVI, to assess sense of values in Japanese adults, showing it aligns with Schwartz's value theory and is suitable for comparing values across age groups.
