I. Chemistry Prize and Precision Metrology
1. The 2026 Nobel Prize in Chemistry goes to Kagan and Soai for nonlinear effects and autocatalysis in asymmetric synthesis
Summary:
On October 7, the Royal Swedish Academy of Sciences awarded the 2026 Nobel Prize in Chemistry to Henri B. Kagan of Université Paris-Sud and Kenso Soai of Tokyo University of Science “for the discovery of non-linear effects and autocatalysis in asymmetric organic synthesis.” The 12 million Swedish kronor prize is shared equally. Life’s chemistry is homochiral: amino acids exist as mirror images, yet proteins use only one. Kagan’s decisive step in 1986 produced a larger excess of one mirror image than had been thought possible. A key 1995 paper from Soai described the first chemical reaction with the potential to be homochiral, and in 2003 he obtained a reaction that formed only one of the two mirror images. Heiner Linke, chair of the Nobel Committee for Chemistry, said they solved a mystery more than a century old: how homochirality can emerge spontaneously. Kagan was born in 1930 in Boulogne-Billancourt and received his PhD in 1960 from the Collège de France. Soai was born in 1950 in Hiroshima and received his PhD in 1979 from the University of Tokyo. Both are emeritus professors.

Commentary:
The prize recognizes a handedness-amplification principle already used in pharmaceutical synthesis, not a reaction that was run for the first time today.
2. Vienna and Tsinghua each publish a thorium-229 nuclear clock that locks its own laser
Summary:
Nature on October 7 published two clocks that take their frequency reference from the thorium-229 nucleus rather than from an electronic transition. In the paper from Thorsten Schumm’s TU Wien group with Germany’s PTB and other partners, a continuous-wave laser is locked to the 148-nanometer nuclear transition in a room-temperature calcium fluoride crystal, and the absorption signal pulls the laser frequency back. The university wrote the same day that the clock stayed stable for more than 24 hours without intervention. Checked over one day, the precision was about 10 to the power of minus 15, roughly one second in 30 million years, still short of the world’s best optical clocks. In the companion paper led by Shiqian Ding’s Tsinghua group, a roughly 10-microwatt, 148.4-nanometer continuous-wave vacuum-ultraviolet laser made by four-wave mixing stabilizes the clock to thorium-229-doped calcium fluoride. The fractional frequency instability is 5×10⁻¹³ divided by the square root of averaging time in seconds. Clock-transition frequencies in two independently fabricated crystals agree at the 10⁻¹³ level. TU Wien said the Chinese group is the second, after Vienna and Braunschweig, to build such a clock.

Commentary:
A nucleus is less exposed to outside disturbance than an electron shell, so the milestone is the new reference, not a record that already beats optical clocks.
II. Spaceflight
3. Crew-12 undocks from the International Space Station at 8:05 a.m. EDT aboard Dragon
Summary:
A NASA space-station log states that at 8:05 a.m. EDT on October 7, NASA astronauts Jessica Meir and Jack Hathaway, ESA astronaut Sophie Adenot, and Roscosmos cosmonaut Andrey Fedyaev undocked from the space-facing port of the Harmony module aboard a SpaceX Dragon. The same log set the return of splashdown coverage for 10:20 a.m. on October 8, with splashdown at approximately 11:34 a.m. off the California coast. After departure, the station still had the Crew-13 Dragon, Northrop Grumman’s Cygnus XL, Soyuz MS-29, and Progress 95 and 96 attached. NASA’s October 6 mission note said the return would complete Crew-12 after 237 days in space, with Meir in command and Hathaway as pilot.

Commentary:
October 7 was the undocking; the crew was not yet in the Pacific, and 11:34 a.m. remains the planned time for the next day.
4. South Korea’s Nuri rocket completes its fifth flight and separates all 15 satellites
Summary:
Xinhua reported on October 7, citing the Korea AeroSpace Administration, that the fifth launch of South Korea’s domestically developed Nuri rocket succeeded and that all 15 satellites separated. At 12:25 p.m. local time (11:25 a.m. Beijing time), the rocket lifted off from the Naro Space Center in Goheung, South Jeolla Province, and placed five Earth-observation satellites and ten CubeSats into the planned orbit. The agency said South Korea plans a ten-satellite Earth-observation constellation, NEONSAT; the five launched today are to be joined by five more planned for next year. Nuri is a three-stage rocket of about 200 tonnes that can send a 1.5-tonne-class satellite to an altitude of 600 to 800 kilometers. The October 2021 debut failed to place a dummy satellite in the planned orbit. Flights in 2022, 2023, and 2025 succeeded.

Commentary:
The flight put satellites in orbit; the ten-satellite NEONSAT constellation still waits on the five spacecraft planned for next year.
5. ESA posts the two main braking burns Hera will use before it matches Didymos
Summary:
An ESA page dated October 7 describes the planetary-defence spacecraft Hera as launched two years ago on that calendar day, now flying at more than 12 kilometers per second relative to Earth and preparing to approach the Didymos binary. The same page also says the launch was on October 7, 2026, just ahead of Hurricane Milton, which conflicts with the “two years ago today” wording and with Milton’s 2024 timeline. The burn plan below is the schedule the page states explicitly. A short test burn was performed on October 2. Early on October 15, three hydrazine orbit-control thrusters will fire together for 93 minutes and cut Hera’s velocity relative to the asteroids by a few hundred meters per second (BRM-1). A second burn of about 31 minutes, BRM-2, is planned for the early morning of October 22 to complete most of the required delta-v and to compensate for any shortfall in the first burn. Three smaller transition maneuvers toward the end of the month are intended to bring the velocity relative to Didymos near zero. The target is a close look at Dimorphos, whose orbit NASA’s DART spacecraft changed by impact in 2022.

Commentary:
October 7 published a braking timetable; the 93-minute main burn is still scheduled to ignite on the 15th.
III. Astrochemistry and Superheavy Elements
6. ALMA detects fully deuterated methanol, CD3OD, around the protostar IRAS 4A2
Summary:
The Max Planck Society reported on October 7 that a team led by Arnaud Belloche of the Max Planck Institute for Radio Astronomy detected fully deuterated methanol, CD3OD, in interstellar space for the first time, using the ALMA COMPASS survey. Every hydrogen in the methanol is replaced by deuterium. The detection is toward the protostar IRAS 4A2 in the Perseus molecular cloud. The Max Planck release places that cloud about 1,000 light-years from Earth; the Astronomy & Astrophysics paper gives a distance of about 290 parsecs for IRAS 4A. The survey observed eleven young stellar systems. The paper reports ten lines that meet the detection criteria for CD3OD, and calls this the first quadruply deuterated interstellar molecule. Preliminary local-thermodynamic-equilibrium models do not detect it in the rest of the COMPASS sample. The abundance is about a hundred times higher than current chemical models predict. Belloche said a key process that builds multiply deuterated methanol therefore appears to be missing from all of them. Six other COMPASS papers appear alongside this one.

Commentary:
The factor of about a hundred means deuterium chemistry in cold clouds is still incomplete in the models, not that a new recipe for planets has been identified.
7. Gas chromatography gives seaborgium hexacarbonyl a first bond-dissociation energy 4 kilojoules per mole below the tungsten homologue
Summary:
Nature on October 7 published an open-access paper by Alexander Yakushev and colleagues; the corresponding-author address is at GSI. The experiment produced 259Sg in the 208Pb(52Cr,1n) reaction at the gas-filled separator TASCA and formed hexacarbonyls on the spot in helium plus carbon monoxide. Volatile Sg(CO)6 and W(CO)6 passed through room-temperature miniCOMPACT and deposited on gold-coated COMPACT, which carried a temperature gradient. Three decay chains starting with 259Sg were recorded in COMPACT and assigned to the hexacarbonyl. From the yields, the first bond-dissociation energy of Sg(CO)6 is 188(9) kilojoules per mole, 4(2) kilojoules per mole lower than that of W(CO)6. The rising trend of group-6 hexacarbonyl bond strengths therefore reverses from tungsten to seaborgium, in line with calculations that destabilize the 6d orbitals. The adsorption enthalpy on gold is 45 kilojoules per mole, with an asymmetric uncertainty of plus 4 and minus 6. The volatile-to-nonvolatile ratio is 0.20±0.01 for tungsten and 0.04 for seaborgium, with uncertainties of plus 0.05 and minus 0.02.

Commentary:
The weaker-bond result rests on three seaborgium events in COMPACT; agreement with theory does not make that small count a large sample.
IV. Biomedicine
8. The FDA grants Temab-A two Breakthrough Therapy designations, for refractory colorectal cancer and previously treated non-small cell lung cancer
Summary:
AbbVie announced on October 7 that the U.S. Food and Drug Administration granted two Breakthrough Therapy designations to the investigational antibody-drug conjugate telisotuzumab adizutecan (Temab-A, ABBV-400). The first, in combination with bevacizumab, is for adults with refractory metastatic colorectal cancer previously treated with a fluoropyrimidine, irinotecan, oxaliplatin, an anti-VEGF antibody, and, if indicated, an anti-EGFR antibody. The second, as monotherapy, is for adults with locally advanced or metastatic EGFR wild-type, c-Met protein-expressing, non-squamous non-small cell lung cancer who have received platinum chemotherapy and an anti-PD-(L)1 antibody. The designations rest primarily on the first-in-human study M21-404 (NCT05029882). OncLive, citing that study the same day, reported an objective response rate of 47.9 percent in the overall EGFR wild-type non-squamous NSCLC population of 48 patients. AbbVie said colorectal and lung cancer together affect more than four million people worldwide each year, and that Temab-A has not been approved by any regulator.

Commentary:
A Breakthrough Therapy designation speeds review; 47.9 percent comes from an early cohort of 48 patients, not from an approved label.
V. Energy and the Ocean
9. UNSW and UtmoLight certify 23.5 percent efficiency on a 676-square-centimeter perovskite submodule
Summary:
The University of New South Wales announced on October 7 that a team led by Xiaojing Hao, working with industry partner UtmoLight, reached a certified stabilized power-conversion efficiency of 23.5 percent on a perovskite solar submodule with a 676-square-centimeter aperture, about 30 by 30 centimeters. That is 0.6 percentage points above the previous benchmark. Laboratory cells are typically about 1 square centimeter. The record was set while removing the nickel oxide layer commonly used at submodule scale to limit short circuits; nickel oxide can also react with the perovskite and adds a process step. Team members including Zhen Li and Ziyue Feng changed materials and fabrication so that a hole-selective contact forms during fabrication. They hope, in the next few months, to make a 2.8-square-meter module closer to commercial size, aiming for about 18 to 19 percent, and they state that efficiency, reproducibility, and long-term stability still have to improve before wide deployment.

Commentary:
The 23.5 percent result shows efficiency can hold at the 30-centimeter scale; a 2.8-square-meter module and long-term stability in heat, moisture, and light are still ahead.
10. A model of a Scottish offshore wind farm associates turbine foundations with about 0.1 to 0.3 degrees Celsius of summer surface cooling
Summary:
The University of Aberdeen reported on October 7 that a team led by Michela De Dominicis of the National Oceanography Centre, with the University of Aberdeen and the Scottish Government Marine Directorate, published PELAgIO results in Scientific Reports. They combined numerical models with field observations, oceanographic instruments, and autonomous gliders at Seagreen, Scotland’s largest offshore wind farm, to study how underwater turbine structures change mixing. In the simulations, the structures enhance mixing, bringing cooler water toward the surface and warmer water toward the seabed. Turbine-related mixing was associated with summer sea-surface temperature drops of about 0.1 to 0.3 degrees Celsius in and around the farm. Under the modelled 2023 marine-heatwave conditions, cooling exceeded 0.5 degrees Celsius in some locations. The size of the effect depends on season, tides, and how layered the water column is, with transitional zones between mixed and stratified water more sensitive. De Dominicis said extra mixing does not always produce a change that is easy to detect.

Commentary:
This is a physical estimate of when an effect would be detectable in deeper stratified water, not a demonstration that wind farms are cooling the ocean at large.
VI. Wide-Bandgap Semiconductors and Macroscopic Spin Force
11. Silicon-doped alpha aluminum-gallium oxide films push the bandgap past 7 electronvolts and yield a diode and an AlphaFET
Summary:
Nature on October 7 published a paper by Jacob Steele, Debdeep Jena, Darrell Schlom, and colleagues. They grew silicon-doped α-(AlxGa1−x)2O3 films by suboxide molecular-beam epitaxy with bandgaps above 7.0 electronvolts, past cubic boron nitride, which they identify as the next-widest-bandgap semiconductor previously known. In the colossal-bandgap regime above 6 electronvolts, the room-temperature conductivity of these films is more than 100 million times higher than all previous reports. The authors fabricated a Schottky diode and a field-effect transistor, the AlphaFET, with a colossal-bandgap channel. The substrate is sapphire, which is produced at large scale. The paper contrasts that with diamond and cubic boron nitride, where wider gaps have tended to mean harder synthesis, higher cost, and smaller size.

Commentary:
Power electronics needs a wide gap that can be doped and built into a device; the paper reports film conductivity and prototype devices, not a power module in production.
12. An Okinawa group uses nitrogen-vacancy spins in diamond to drive a 128-milligram levitated resonator
Summary:
Phys.org reported on October 7 that Jason Twamley’s Quantum Machines Unit at the Okinawa Institute of Science and Technology published in Science Advances a result in which force from electron spins moved a centimeter-scale object subject to gravity. The preprint states that an ensemble of nitrogen-vacancy defects drives the center-of-mass motion of a diamagnetically levitated oscillator with a mass of 128 milligrams. Periodic green-laser initialization of the spins produced motional amplitudes above 100 nanometers in air. The preprint also gives a vertical resonance of 17.6 hertz, a quality factor of 55, and amplitudes up to about 1.5 micrometers in vacuum. The apparatus is a diamagnetically levitated graphite plate linked by a carbon rod to a diamond, containing billions of nitrogen-vacancy centers, suspended above a magnet. A small mirror on the graphite plate is read by an interferometer. Twamley told Phys.org that what they observed is a classical mechanical response to a quantum force, on an object eight to nine orders of magnitude more massive than existing spin-mechanics experiments.

Commentary:
The motion that was measured is a classical center-of-mass displacement, not a Schrödinger-cat state already placed in the regime of general relativity.
