From French outpost to Euro-Canadian corridor? Why Carney and Macron met in Saint-Pierre-et-Miquelon
Canadian Prime Minister Mark Carney did not need to cross the Atlantic to meet Emmanuel Macron on French soil over the weekend. Instead, he joined the French president in Saint-Pierre-et-Miquelon, just 25 kilometres off Newfoundland. It was the first official visit to the archipelago by a Canadian prime minister. The…
An intermediate caught in the making of fluorescent protein color
ClaimA hydroperoxy intermediate species, stabilized in non-photoactivated PAmCherry1, is a key step in the oxidative maturation of fluorescent protein chromophores.
Safety research from frontier AI labs should be replicated independently and open-sourced
ClaimEmpirical safety results published by frontier labs are generally not replicated or independently verified by external researchers.
Tiny molecular scissors reveal how crystals bend without breaking
Tiny molecular scissors reveal how crystals bend without breaking Lisa Lock Scientific Editor Robert Egan Senior Editor Crystals are usually thought of as rigid and brittle. Yet some molecular crystals can bend, jump, twist or even change shape when exposed to light. Understanding how tiny molecular movements inside a…
How to tackle persistent drought: Lessons from British Columbia
How to tackle persistent drought: Lessons from British Columbia Swati Mestri Scientific Editor Andrew Zinin Chief Editor British Columbia has endured another extreme drought, with damaging impacts across the province, including a watershed emergency declared by the Syilx Okanagan Nation, 70% water-use reductions for a…
The impact of macroprudential policy fragmentation on corporate lending – evidence from a novel indicator
We construct a novel bank-level index that quantifies fragmentation in the capital buffer framework faced by euro area banks. Defined at quarterly frequency, it measures fragmentation by looking at the number of simultaneously active buffers, their geographical dispersion, and the frequency of buffer rate changes with…
How inflation narratives in the press predict inflation risk premia
ClaimInflation risk premia are inversely related to NetDemand, the press-based measure of demand versus supply narratives, in both the euro area and the US, across maturities.
African smoke brightens clouds, but weather patterns offset its cooling effect
African smoke brightens clouds, but weather patterns offset its cooling effect Sadie Harley Scientific Editor Robert Egan Senior Editor Smoke from African agricultural fires brightens clouds over the southeast Atlantic—but new research from scientists at the University of Miami Rosenstiel School of Marine, Atmospheric…
School holidays are coming. Here's how families can keep some sort of routine
School holidays are coming. Here's how families can keep some sort of routine Swati Mestri Scientific Editor Andrew Zinin Chief Editor School holidays mean more free time and less structure. School drop-offs and pickups disappear, bedtimes may shift, and families may need to organize child care, travel or visits with…
Parental gambling affects children's health and schooling
ClaimChildren of risky gambling parents have poorer physical and mental health and lower school engagement than children of non-risky gambling parents.
Rotating molecules that invert circularly polarized light
ClaimSolvent polarity inverts the circularly polarized luminescence of these molecular rotor aggregates twice, by shifting the balance between two excited states.
Nanoparticles that protect healthy tissue from radiation while making tumors more vulnerable
ClaimThe cLAN nanoparticle achieved 100% 30-day survival in mice with subcutaneous and orthotopic tumors while simultaneously protecting normal tissue from radiation.
A ligand-free catalyst that swaps fluorine in molecules for gallium
ClaimA ligand-free Ni–Ga heterometallic system can gallylate C(sp2)–F bonds in electron-rich fluoroarene substrates by dynamically switching between bimetallic and trimetallic regimes.
Neighboring peptide helices synchronize: block sequence and double-stapling topology control helix inversion speed
ClaimIn nonoverlapping doubly stapled peptides, the α-α architecture has a helix-inversion half-life approximately 800 times longer than the singly stapled analogue.
Negatively Curved Carbon Nanohoops as Cut-Outs of Toroids and Schwarzites
ClaimNegatively curved carbon nanohoops of 152, 228, and 304 atoms were synthesized, and two were structurally elucidated by single-crystal X-ray diffraction.
Liquid metals change how nickel converts CO2
ClaimContact with liquid indium at room temperature makes CO2 hydrogenation on nickel oxide produce CO with over 99% selectivity instead of methane.
Ternary-ion batteries: aluminum cells with high energy and fast charging
ClaimAn Al/eGr-PTO pouch cell with a capacity of about 18 mAh achieved a cell-level specific energy of 84 Wh/kg, with the electrolyte unchanged throughout cycling.
A human nasal spray reduces bleeding in dogs undergoing surgery
ClaimDogs given 0.1% intranasal xylometazoline before surgery had 62% less intraoperative bleeding than dogs given saline.
Administrative help plus community pressure: how Mumbai households got running water
ClaimCombining administrative assistance with community advocacy increased official water connections by 45% compared with households without assistance, while each intervention alone had no effect.
Why local food isn't reaching schoolchildren's lunch trays
ClaimThe lack of midscale supply chains for processing local products is a major obstacle to U.S. schools' procurement of local food.
