How Virus-like ‘Jumping Genes’ Became Our Partners in Evolution
How Virus-like ‘Jumping Genes’ Became Our Partners in Evolution Introduction You might imagine that the DNA in your cells has a simple history. Even though it’s been recombined in every generation through sex and gained the occasional mutation, on the whole the genome has been stable and has been passed down reliably…
N-Modulated Graphdiyne Iron Single-Atom Nanozyme through Long-Range Interactions for Photothermal Amplified Multifunctional Catalytic Antibacterial Therapy
The rational design of single-atom nanozymes (SAzymes) can be achieved by regulation of the first and second coordination shells near the metal coordination center. However, the impact of structural changes at distances further away from the metal coordination center on the catalytic activity has been rarely reported.…
Validation of a Rapid Screening Method for Textile Additives with Applications to Firefighter Station Wear
Firefighters have previously received attention for their occupational exposure to numerous chemicals of concern through their turnout gear, aqueous film-forming foam, and fire events. However, their station wear, uniforms worn daily in the station, has not yet been investigated for textile additives of concern. In th…
Activating the Anomalous Jahn–Teller Effect in NASICON-Type Mixed Phosphate Cathode via Crystal Field Engineering
High-voltage Mn3+/Mn2+ redox reactions in polyanionic cathodes offer the potential to increase energy density while reducing the cost of batteries. However, its practical application is hindered by sluggish reaction kinetics and asymmetric Jahn–Teller distortion. Herein, we report a NASICON-type cathode, Na3.85□0.15Mn…
Tailoring Ion-Transport Networks for Wide-Temperature Mg-Organic Batteries
Developing high-performance magnesium metal batteries is hindered by sluggish Mg2+ diffusion kinetics and the structural instability of conventional cathodes. Here, we propose a design principle for organic cathodes by regulating polymer spatial configurations, which facilitates multidirectional Mg2+ transport and enh…
An Explainable Multi-Modal Deep Learning Framework for Investigating the Influences of Dynamic Environmental Exposure on Momentary Stress
Urban stressors pose critical public health concerns by adversely affecting residents’ mental health. However, past studies have mostly focused on single-modal stressors under static exposure paradigms, with limited exploration of nonlinear environment-stress relationships. This study proposes an explainable multimoda…
Fluorine-free self-cleaning superhydrophobic filters for humid flue gas filtration
ClaimThe fluorine-free antifouling-coated filter achieves an average cleaning cycle of 550.84 s and average residual pressure drop of 280.69 Pa, better than the unmodified medium.
Why Carney and Macron met on a French island near Newfoundland
ClaimThe Carney–Macron meeting in Saint-Pierre-et-Miquelon marks Canada's strategic rapprochement with Europe as a response to American economic pressure.
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.
Living with chronic pain at work: Supportive managers can help, but they can't solve everything
Living with chronic pain at work: Supportive managers can help, but they can't solve everything Swati Mestri Scientific Editor Andrew Zinin Chief Editor "I don't want the pain to define me. I want me to define me." This was how one employee described working with chronic pain in interviews conducted in 2021 by one of…
Environmental science takes an average of seven years to influence international policy, study finds
Environmental science takes an average of seven years to influence international policy, study finds Lisa Lock Scientific Editor Robert Egan Senior Editor A new study led by the University of Alicante (UA) and the Mediterranean Center for Environmental Studies (CEAM) analyzes the barriers separating scientific knowled…
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.
Seven of nine planetary boundaries breached, at record levels
ClaimAll seven transgressed planetary boundaries are, in 2026, at their highest recorded levels of transgression.
The purple face of Mars' south pole
ClaimThe purplish hues of Mars' south polar region come from a combination of dust, carbon dioxide frost and light, not from a distinct purple material.
Continuously tunable X-ray light, like a slide guitar
ClaimBy reshaping the driving laser's spectrum in a gas-filled waveguide, X-ray frequencies can be shifted continuously between harmonics while preserving brightness and narrow spectral lines.
Where the first supermassive black holes were born: simulations of direct collapse
ClaimMassive black hole seeds could form via direct collapse 13.64 billion years ago, and metal enrichment stopped this process between 13.5 and 13.4 billion years ago.
Flies, mice and humans walk by the same principle of joint speeds
ClaimIn fruit flies, mice and humans, leg joints farther from the center of the body move faster than those closer to it, and this velocity gradient remains unchanged with aging.
What Nepal can learn about post-disaster reconstruction from its 2015 earthquake
ClaimAfter the 2015 earthquake, property-based reconstruction grants left many affected people ineligible, increasing their vulnerability.
Crystals that bend without breaking, explained by a molecular network of scissors
ClaimIn these crystals, molecules form scissor-like joints, and their starting position determines whether the crystal bends elastically or fractures under strain.
Persistent drought in British Columbia: lessons for proactive water management
ClaimWater management in British Columbia rests on an assumption of abundance and treats drought as a short-term emergency, even though it has become a persistent year-round problem.
