It's Earth Science Week!🌎 Celebrate by getting outside & admiring fall foliage with the @GLOBEProgram's North American Phenology Campaign.🍂 Your observations can help PACE scientists better map leaf color from space! Get started:

Have a research idea that could advance NASA science? 🔬 NASA plans to release ROSES-27 by January 2027, with over 50 research opportunities spanning astrophysics, Earth science, planetary science, heliophysics, space biology and more. Start planning:

We're testing our new benchmark. STEMBench is a set of 120 research-level problems from 6 domains - Biology, Chemistry, Physics, Astronomy, Earth science, Engineering - 20 problems per domain. Very cool to see that our initial calibration works well and the benchmark is far from saturated (max score is 4 per domain). Detailed testing with a dedicated website incoming. Interestingly, it seems like physics will be next after mathematics. Math is not included in this benchmark, we have ErdosBench for that. DM me if you want to see your model tested.

Claude Code can now work like a research scientist. K-Dense open-sourced 177 science skills for coding agents: - Drug discovery: query ChEMBL, screen molecules with RDKit and DiffDock - Single-cell RNA-seq analysis with Scanpy - 100+ scientific databases in one place - Biology, chemistry, medicine, physics, engineering, Earth science - Works with Claude Code, Codex and Cursor 52K stars. free.

HURRICANE ISAIAS UPDATE - 8:00 AM ET PATH • NEW (NHC Intermediate Advisory 11A, 7 AM CDT): "ISAIAS ON THE CUSP OF MAJOR HURRICANE STRENGTH"; 110 mph (1 mph below Cat 3), pressure down to 958 mb (from 963 mb at the 5am advisory), 27.0N 87.7W, ~245 mi S of Pensacola, NNE 15 mph. No watch/warning changes. • Corroborates the overnight recon tip (973 to 962 mb) and the "likely Cat 3 this morning" tip. • Forecast peak ~121 mph Cat 3 midday; landfall tonight near Pensacola/AL-FL line. • Surge Warning mouth of Mississippi River to Suwannee River: 5-7 ft Ocean Springs to Indian Pass; 3-7 in rain (up to 10-15 localized). • TS-force winds earliest reasonable arrival Pensacola Beach ~1 PM CT (most likely 2 PM CT); Navarre Beach ~2 PM CT earliest (most likely 3 PM CT). NHC_TAFB peak seas near 32 ft. • Unconfirmed X tip: DeSantis in Pensacola Saturday 7am with Ashley Moody for an Isaias update. DeSantis (X, Oct 7): preparing for landfall in the Mobile-Pensacola region as a category 3. RIGS • No new BSEE report; Thursday 11am CT numbers stand: ~1.28M bpd / 62.9% of oil shut in, 57.4% of gas (~1.13 Bcf/d); 121 of 371 platforms evacuated; 5 non-DP rigs evacuated, 4 DP rigs moved off location; 12 companies reporting. • Next report expected this afternoon (~2pm ET). • BP shut in Na Kika and Thunder Horse (all personnel off), non-essential off Argos, Atlantis, Mad Dog. Shell halted Mars, Olympus, Ursa, Vito, Appomattox. Chevron shut in production at five Gulf facilities. Harbour curbing select facilities. • Earth Science Associates: ~9M barrels of total production lost. Enki's Watson: under a week if the track holds; Enki damage estimate over $4.5B if effects extend eastward to Pensacola/Eglin AFB. REFINERIES • Still no shutdown announced. Pascagoula remains the plant at risk. • Argus: Pascagoula (356,000 bpd) named among the threatened onshore refineries; Louisiana complex (Chalmette, Garyville, Norco, St Charles) likely to be spared the most severe impacts on the current track. • Chevron: onshore facilities "continue to follow our established storm response procedures and are closely monitoring the projected path." • ~500,000 bpd of refining capacity in the path incl. Chevron Pascagoula (369,000 bpd, gasoline/diesel/jet/premium base oils); Vertex Saraland north of Mobile near the track; Hunt Refining assets + Mobile Bay import docks (Plains, Vertex, Hunt) exposed via port closures. • Jefferies calling it a "fuel supply event"; Mizuho's Yawger: "could be a gigantic event." • Retail diesel $6.30 vs $3.68 a year ago; diesel crack near $64/bbl vs ~$25 a year ago (EIA Oct 6). TERMINALS/PORTS • Port of Mobile under Port Condition Yankee (gale-force winds expected within 24h); vessel operations at public berths suspended since 1pm ET Thursday. • Ports of Plaquemines, New Orleans, St Bernard set to X-ray Oct 7, still open to commercial traffic. • Pensacola International suspends commercial ops 10am CT Friday. Mandatory evacuations Zones A and B, Pensacola Beach and Perdido Key. • AL Gov. Ivey ordered tourists/visitors south of the Gulf ICW in Baldwin County plus Dauphin Island to evacuate; 9 AL county state offices closed noon CT Friday; 40-county state of emergency. DeSantis expanded FL emergency to 27 North Florida counties. • MISO conservative operations through Oct 10 6pm ET. Mexico's Tuxpan closed since late Monday. SPC severe storm threat Friday and Saturday across the Panhandle/South AL/South GA. DAMAGE • None reported pre-landfall; landfall roughly 10-14 hours out. • Tornado-spawn threat across north Florida; tornado warnings possible overnight. Storm remnants forecast over Kentucky, southern Indiana, Tennessee this weekend. MARKET READ • Brent $103.16 (-0.8%), WTI $90.55 (-0.9%), essentially flat vs the earlier prints. • Driver: Trump ruled out new Iran strikes before the midterms, easing Middle East escalation fears; the 63% of Gulf oil shut in plus Houthi risk premium limiting the decline. • Nat gas Henry Hub $3.13 (-4.6%). • Thursday settle: WTI up 3.6% to $91.49, Brent up 4.1% to $104.28 (touched $105.50 intraday).
