Journal that published 'Susceptibility and regulation of biomolecular condensates by solutes' on July 30 (DOI 10.1073/pnas.2604434123).
No evidence-backed relationships are recorded.
Researchers report that X's For You algorithm promotes value-incongruent posts because replies signal disagreement, and that the mismatch is over four times larger for Democrats.

Digital reconstructions of two Neanderthal pelvises put the childbirth-versus-bipedalism trade-off under strain, and point at the pelvic floor instead.
Reality
A PNAS study reports the first direct evidence that Natufian foragers on Mount Carmel ate lizards and snakes, across 20 settlement layers spanning roughly 3,000 years.
Reality
A Texas A&M team reports in PNAS that excess RNA impairs mitochondria before the immune system reacts. The quantity of RNA matters, not only what it encodes.
Reality
A PNAS study argues high proliferation can lower rates of early abnormal growth, and moon jellyfish experiments track the prediction. The reported evidence is directional, not quantified.
Reality
A PNAS study pooling more than 2,000 flux measurements from 87 studies finds plant species alone explain 62% of methane variability in tidal marshes, outperforming salinity.
Reality
A PNAS study that instrumented 715 real feeds found X amplified content clashing with users' stated values. The named mechanism is engagement weighting, not content merit.
Reality
A Montana State-led study in PNAS reads pollen, charcoal, arsenic and diatoms from closed lakes in the Lower Geyser Basin. Its framing: dry centuries brought less hydrothermal activity and more fire.
Reality
A decade of borehole data from Ontario's Kidd Creek mine puts about 140 tonnes of hydrogen a year escaping unused. That is roughly where the evidence stands.
Reality
A new PNAS paper collects nine surprises from more than three decades of monitoring in Dutchess County. Acorns and mice track nymphal tick numbers; deer abundance does not.
Reality
A PNAS paper from Eric Dufresne's lab reports an experimental metric for comparing how chemicals act on three unrelated condensate types. The claimed payoff is prediction instead of enumeration.
