A paper published in Nature on 14 October 2026, with Richard A. Friesner of Columbia University as corresponding author, reports evidence for multi-lithium-ion clustering in lithium-ion battery electrolytes. The team combined machine-learning-enabled atomistic simulations, nuclear magnetic resonance spectroscopy, electrochemical data and quantum-chemical calculations. They identify complexes holding several lithium ions, with no bound anions, coordinated only by ethylene carbonate, and describe these complexes as uniquely facile for reduction. In the simulations the share of lithium ions sitting in such clusters rises from about 23 per cent at 0.5 molar concentration to over 68 per cent at 2 molar. The machine-learning force field was fitted only to gas-phase cluster calculations yet reproduced a range of condensed-phase measurements. The authors present the role of these clusters in solid electrolyte interphase formation as a hypothesis rather than a demonstrated result.
Lithium ions in clusters at 0.5 molar:
about 23%
Lithium ions in clusters at 2 molar:
over 68%
Solvent coordinating the clusters:
ethylene carbonate
Why it matters for exams: Battery chemistry questions increasingly ask what happens inside the electrolyte, not only at the electrodes.

A paper published in Nature on 14 October 2026, with Sheng Ding of Tsinghua University as corresponding author, reports continuous development outside the womb of mouse embryo models grown only from chemically induced totipotent-like stem cells. The cells self-organised into blastocyst-like structures that resembled natural blastocysts in shape and in the separation of cell lineages. The resulting models then went through gastrulation, embryonic axis formation, blood formation and early organ formation, closely resembling natural embryos at embryonic day 8.5. With longer culture the models developed functional cardiac tissue that the authors describe as highly comparable to natural embryos at day 10.5. The authors conclude that a single induced cell type can recapitulate much of early mouse embryogenesis and offer the system as a model for studying mammalian development.
Stage reached:
embryonic day 8.5 equivalent
Cardiac tissue comparable to:

A paper published in Nature on 14 October 2026 reports that the surface of a microplastic particle in water is chemically active. Polystyrene microplastics degraded about 90 per cent of the dye methyl orange over ten days in water but not in other solvents, and electron spin resonance spectroscopy confirmed hydroxyl radical production at the particle-water interface. Six commodity plastics, namely polypropylene, polyethylene, polystyrene, polyvinyl chloride, polyethylene terephthalate and polymethyl methacrylate, all generated radicals, with more hydrophobic surfaces more active. Adding the surfactant Triton X-100 reduced radical generation, surface charge and the accumulation of a hydrophobic dye on the particle surface. Charged biomolecules such as proteins and DNA accumulated on the particle surfaces, the radicals promoted protein aggregation, and the particles damaged mouse red blood cells. The authors conclude that plastics in microplastic form are not chemically inert and that this reactivity may contribute to health and environmental harm.
Dye degraded by polystyrene in water over ten days:
about 90%

A study published in Nature on 15 October 2026 reassessed the International Union for Conservation of Nature Red List status of 892 reef-building coral species that were first assessed in 2008. Of these, 774 species had enough data to be assessed, and 340 of them, or 44 per cent, were classified as threatened. The breakdown is 33 Critically Endangered, 251 Endangered and 56 Vulnerable. Most listings follow from projected thermal stress: because species-level population trends are rarely available, the authors inferred population reductions from global coral cover trends and projected annual severe bleaching under the SSP2-4.5 scenario over three decades, then adjusted the estimates with trait-based vulnerability scores. The authors note that the assessment predates the fourth global coral bleaching event of 2023 to 2025 and the first annual mean exceedance of 1.5 degrees Celsius of warming. The paper cautions that the Red List measures relative extinction risk and does not predict whether or when a species may go extinct.
Species assessed:

Background
The Ozone Secretariat of the UN Environment Programme describes the Montreal Protocol on Substances that Deplete the Ozone Layer as a global agreement to protect the Earth's ozone layer by phasing out the chemicals that deplete it.
The phase-out plan covers both the production and the consumption of ozone-depleting substances.
The agreement was signed in 1987 and entered into force in 1989.
The parties to the Protocol meet once a year to take decisions on its implementation, and the Protocol has been adjusted or amended six times since its creation.
The most recent amendment, the Kigali Amendment, called for the phase-down of hydrofluorocarbons, or HFCs.
HFCs were used as replacements for ozone-depleting substances that the original Protocol eliminated; they do not deplete the ozone layer but are powerful greenhouse gases and so contribute to climate change.
The Ozone Secretariat records that the Protocol has met its objectives so far and that the ozone layer is well on its way to recovery.
Signed:
1987
Entered into force:
1989
Times amended or adjusted:

A study in Nature has modelled how much the earliest four-limbed land animals could move their necks.
Because the fossil animals had an axial column dominated by soft tissue rather than fused bone, the team ran material tests on the axial columns of sturgeon, a living fish with a similarly configured notochord-dominated column.
The model found the soft-tissue-dominated column was surprisingly rigid even though it lacks co-ossified vertebral components.
Most stem tetrapods could move their heads less than 6 degrees laterally and less than 3 degrees dorsally, and could not rotate them at all.
Neck mobility did not change as the gap between head and shoulder widened from Eusthenopteron to more crownward stem tetrapods, so the authors argue that forelimb-driven locomotion, not a need to turn the head, explains that separation.
Lateral head movement:
Less than 6 degrees
Dorsal head movement:
Less than 3 degrees

A paper in Nature reports a year-long single-blind test of how well satellites detect and measure methane leaks.
The test covered 746 events: 481 controlled methane releases ranging from 9.5 to 1,183.7 kg/h and 265 blank controls.
The releases were made in Arizona and timed with overpasses from 12 government, commercial and non-profit satellites, and 15 analysis teams from nine countries produced over 2,250 estimates.
Instruments built for the purpose achieved a 92 to 100 per cent true positive rate with a 0 to 11 per cent false positive rate, while repurposed instruments detected 62 to 88 per cent of releases.
The authors note that 79 per cent of false positives came from methods based on artificial intelligence, and that ground-measured cloud cover above 20 per cent degraded performance across systems.
