Scientists more than doubled the known cases of parental care in harvestmen and reconstructed its evolutionary history for the first time. The study found that maternal care evolved only from no care, while paternal care evolved repeatedly from either no care or maternal care, highlighting distinct evolutionary pathways. https://academic.oup.com/zoolinnean/article-abstract/207/2/zlag061/8707815

Australian researchers found that native bees nesting in plant stems are likely the most vulnerable to climate warming, while ground-nesting species can buffer extreme temperatures by sheltering underground. The study suggests that nesting behavior may be a stronger predictor of climate risk than heat tolerance alone. https://www.nature.com/articles/s41467-026-73689-7

Researchers developed a dual-mode magnetic elastomer that moves under a DC magnetic field and rapidly self-destructs under a high-frequency AC field, using embedded Fe₃O₄ nanoparticles to enable both actuation and heat-triggered degradation. The material could power soft robots and secure electronics that operate in hard-to-reach environments and then vanish without leaving traces. https://advanced.onlinelibrary.wiley.com/doi/10.1002/adfm.75790

An analysis of Midwest soybean fields found that fungicide-treated seeds produced only small yield gains (around 22–36 kg/ha) that often failed to offset treatment costs. The results suggest farmers may benefit more from reducing input costs and using treated seeds only in high-risk situations, given limited profits and potential ecological impacts. https://www.nature.com/articles/s41598-026-47390-0

In an early trial, a one-time gene-editing therapy (VERVE-102) reduced “bad” LDL cholesterol by up to 62% in high-risk patients, with effects lasting up to 18 months and no serious safety concerns. By permanently switching off the PCSK9 gene in the liver, the treatment could offer a long-term alternative to daily cholesterol-lowering medications. https://www.nejm.org/doi/10.1056/NEJMoa2601283

In mice, inhaled PET microplastics persisted in the lungs for at least two weeks, triggered inflammatory responses, and worsened allergy-related immune reactions, especially when combined with allergens like ragweed pollen. The findings suggest microplastics can actively modulate immune function, underscoring potential health risks that warrant further study in humans. https://www.sciencedirect.com/science/article/pii/S2772416626002226?via%3Dihub

Researchers found in mice that the stress hormone cortisol helps close early-life critical periods by activating glucocorticoid receptors in astrocytes, triggering a gene program that matures the extracellular matrix and limits neural plasticity. The same pathway appears in humans, suggesting a shared mechanism that could shape brain development and influence conditions linked to altered timing of critical-period closure. https://www.nature.com/articles/s41586-026-10512-9

Researchers developed a fully optical artificial synapse that uses a rare-earth-doped crystal to both sense and store information with light, mimicking short-term synaptic plasticity without electrical signals. Integrated with an imaging sensor, the device enabled in-sensor noise reduction and improved image recognition accuracy, pointing toward energy-efficient neuromorphic vision systems. https://www.spiedigitallibrary.org/journals/advanced-photonics/volume-8/issue-04/046001/Fully-photon-modulated-synaptic-devices-with-bidirectional-plasticity-for-neuromorphic/10.1117/1.AP.8.4.046001.full

Researchers developed an AI model that integrates knowledge from different catalyst families to discover new materials for green hydrogen production. The system successfully predicted and guided the synthesis of a high-performance multimetallic single-atom catalyst for the oxygen evolution reaction, demonstrating that AI can identify entirely new catalyst classes beyond traditional material boundaries. https://www.nature.com/articles/s41563-026-02622-6

A large meta-analysis and new experiments show that aging affects motor learning in a nuanced way: older adults perform worse in explicit, strategy-based learning but show stronger implicit, automatic recalibration. The findings suggest that sensorimotor learning does not uniformly decline with age, as some unconscious adaptation processes may remain intact or even improve. https://www.nature.com/articles/s41562-026-02468-7

Researchers improved iron-based phosphate cathodes for sodium-ion batteries by selectively replacing iron atoms with vanadium ions, activating previously inactive sodium sites. The modified material achieved higher capacity, a 52% boost in energy density, and exceptional durability over 10,000 cycles, advancing the potential of affordable, high-performance sodium-ion batteries. https://www.nature.com/articles/s41560-026-02059-w

Researchers identified conserved gene-expression markers that track aging and mortality across mammals, analyzing over 11,000 samples from multiple species. The resulting universal transcriptomic clock can estimate biological age, predict mortality risk, and detect effects of disease or rejuvenation, offering a cross-species tool for longevity research. https://www.nature.com/articles/s41586-026-10542-3

Researchers showed that stomatal orientation in developing leaves is guided primarily by cell geometry but can be redirected by mechanical stress generated during growth. Using live imaging and modeling, they found tensile forces across the leaf influence how guard cells divide, revealing a dual control system that links tissue mechanics to pore patterning. https://www.cell.com/cell-reports/fulltext/S2211-1247(26)00444-4

Researchers identified and structurally characterized a new β-1,2-glucan-binding protein involved in transporting these sugars into bacteria. The protein selectively binds both linear and cyclic β-1,2-glucans through a conserved core interface, revealing previously unknown diversity in glucan transport systems and offering potential targets for crop protection and biotechnology applications. https://febs.onlinelibrary.wiley.com/doi/10.1111/febs.70576

Researchers found that deer keds reduce activity of vision-related opsin genes by about half after shedding their wings and becoming permanent parasites on a host. The shift suggests they scale back visual sensitivity to conserve energy for functions like digestion and reproduction once flight and host-seeking are no longer needed. https://dx.doi.org/10.1242/jeb.251571

A new modeling study suggests that the dusty outer regions of disks around supermassive black holes in active galaxies could host large-scale planet formation. Under these extreme conditions, planets may form rapidly and grow to massive sizes, potentially even reaching stellar mass, implying that AGN disks could contain vast populations of exotic worlds. https://arxiv.org/abs/2605.19241

Astronomers identified the origin of a rare long-period radio transient as a white dwarf pulling material from a close red dwarf companion in a compact binary system. The system produces repeating radio and X-ray bursts every 1.4 hours, confirming that at least some of these mysterious signals arise from accreting white dwarf binaries rather than slow-spinning neutron stars. https://www.nature.com/articles/s41550-026-02882-x

Harvard researchers developed a tougher, stiffer polyvinyl alcohol (PVA) hydrogel scaffold that safely contains engineered bacteria while allowing them to release therapeutic drugs. The material prevented bacterial escape for six months in lab tests and reduced infections in mice by detecting Pseudomonas aeruginosa and releasing antimicrobials. The approach advances safer “living” implants for treating infections and potentially cancer. https://www.science.org/doi/10.1126/science.aec2071

Penn researchers developed a new light-based switching method using exciton–polaritons—quasiparticles that combine photons with electrons in ultra-thin semiconductors. This approach enables ultra-low-energy, all-light signal switching, potentially overcoming key limits of electronic computing and improving the speed and efficiency of AI hardware. https://journals.aps.org/prl/abstract/10.1103/gc15-qsvf

Researchers discovered that neurons use an indirect delivery route, called transcytosis, to send key proteins along their long axons. Studying the TrkA receptor, they found it first travels to the cell surface, is pulled back inside, then transported in vesicles along axons by the motor protein KIF1A. This pathway, triggered by nerve growth factor, is crucial for maintaining synaptic transmission and may inform future treatments for nerve injury and neurodegenerative disease. https://www.science.org/doi/10.1126/scisignal.aea7078
