METABOLIC PATHWAYS. “Centrally located within this network are the sugar phosphate reactions of glycolysis and the pentose phosphate pathway. Together with the overlapping reactions of the Entner–Doudoroff pathway and of the Calvin cycle, they provide the precursor metabolites required for the synthesis of RNA, DNA, lipids, energy and redox coenzymes and amino acids—key molecules required for life.” https://www.embopress.org/doi/full/10.1002/msb.20145351 View in LinkedIn

FINDING. “In this Letter, we have shown that the BBHs observed by LIGO/Virgo strongly disfavour the existence of scalar ultralight bosons with masses in the range 1.3 × 10(−13) eV ≤ μs ≤ 2.7 × 10(−13) eV. The statistical evidence is entirely contributed by the two highly spinning primaries in the systems GW190412 and GW190517.” (BBH = binary black holes). https://lnkd.in/gnQbwGA View in LinkedIn

THE BOTTLENECK. “Another important factor to assess if black holes will be spun down by boson clouds is the time interval between the formation of the black hole and the merger: if a black hole merges too quickly after being born it might not have the time to undergo superradiance, even if bosons of the appropriate mass exist.” https://lnkd.in/gnQbwGA View in LinkedIn

SUBLINEAR SCALING. “It means a city with a large population needs only ~80% as many roads, power lines, and gas stations per person as a city half its size. The second, “superlinear scaling,” applies to outputs of socioeconomic activity. It means a large city produces ~120% more wealth, patents, crime, pollution, and disease per person than a city half its size.” https://www.santafe.edu/news-center/news/researchers-reveal-cloud-geometry-behind-city-scaling View in LinkedIn

ULTRALIGHT BOSONS. “The evidence against the existence of bosons with this mass arises mainly from two highly spinning black holes found in the new data set, namely GW190412 and GW190517.” https://lnkd.in/gnQbwGA View in LinkedIn

SELF SIMILARITY. “The core structure of the metabolic network is very similar across all organisms, which suggests an early origin during evolution.” https://www.embopress.org/doi/full/10.1002/msb.20145351 View in LinkedIn

HUNTING THE ULTRALIGHT SNARK. “In this Letter we repeat the analysis of Ref. [64] by including the 35 new binary black holes reported by the LIGO-Virgo-Kagra collaboration at high significance. We find the probability a scalar boson with masses in the range 1.3×10(−13) eV ≤ μs ≤ 2.7×10(−13) eV to be smaller than 0.01%.” https://lnkd.in/gnQbwGA View in LinkedIn

THE ORIGIN OF LIFE. “This question has been sometimes heavily debated, backdropped with the vexing question of the origin of RNA and its sugar–phosphate backbone.” https://www.embopress.org/doi/full/10.1002/msb.20145351 View in LinkedIn
