Breaking the durability–degradability trade-off in polymers

Osaka, Japan — Modern polymer materials face a fundamental challenge: they must remain strong and durable during use, yet ideally degrade when they are no longer needed. Designing materials that satisfy both requirements has long been a major challenge in polymer science. Researchers at The University of Osaka have now developed a molecular design strategy that reconciles these competing demands. By introducing movable molecular rings (cyclodextrins) into a polymer network, the team created a tough material whose enzymatic degradation can be switched on or off using light. In conventional polymer materials, strong mechanical properties are typically achieved by ...

Study examines how autonomous vehicles may change morning commutes

Autonomous vehicles (AVs), which already operate on the roads of several major U.S. cities and in countries worldwide, are expected to play a large role in shaping the future of cities. In a new study, researchers investigated how AVs may change travel patterns during morning commutes and affect parking in business districts. By providing insights into the changes associated with parking and traffic congestion as the use of AVs rises, the study can inform urban planning efforts. Conducted by researchers ...

Drone footage captures sperm whales headbutting each other for the first time

Researchers at the University of St Andrews used drones to film sperm whales headbutting one another in the Azores and Balearic Islands - the first scientific documentation of a behavior that 19th-century whalers described and that inspired Herman Melville's Moby Dick. Surprisingly, it was sub-adults, not large males, engaging in the collisions.

The $60 billion perfume industry depends on plants it does nothing to protect

With 45% of flowering plants at risk of extinction and the fragrance market heading toward $100 billion by 2034, researchers argue in BioScience that the industry must move past sustainability branding and directly finance plant conservation.

Three mechanical 'knobs' predict body shape across corals, jellyfish, and anemones

Corals, jellyfish, and sea anemones share a common ancestor but have wildly different body shapes. A new study identifies three mechanical tissue properties - 'mechanotypes' - that predict and even control which form an organism takes.

Uncovering structural cue use in second-language sentence processing

People often seem to understand language before they have actually heard enough words to determine its structure. In everyday conversation, listeners react immediately, anticipate what others will say, and rarely wait for a sentence to finish. This raises the question of how the brain is able to keep up with such rapid communication. In a new study, an international team of researchers, led by Associate Professor Chie Nakamura from the School of International Liberal Studies, Waseda University, Japan, investigated how listeners interpret structurally ambiguous sentences in ...

Turning sawdust into fire-resistant materials

Every time a tree trunk is sawn, it creates sawdust. Millions of tonnes of sawdust are produced every year worldwide, with most of it is burned to generate energy. This releases the carbon dioxide stored in the wood back into the atmosphere – which is not ideal from an environmental perspective. Now, a team of researchers at the Chair of Wood Materials Science at ETH Zurich and Empa has developed a process that can convert sawdust into a recyclable and environmentally friendly composite using the mineral struvite, a crystalline, colourless ammonium magnesium phosphate. This, in turn, keeps the sawdust in the material cycle for longer. Struvite has ...

An acoustic tractor beam that makes materials soft on one side and stiff on the other

A UC San Diego-led team demonstrated that acoustic waves can controllably move mechanical kinks - boundaries between soft and stiff regions - through a specially designed material, creating what amounts to remote control over how a material feels and behaves.

Disposable gloves become CO2-capturing materials in a single chemical step

Less than 2% of nitrile rubber gets recycled. Chemists at St Andrews developed two catalytic routes that convert used nitrile gloves into polyamines and polyols - useful industrial chemicals - with the polyamines also capable of capturing carbon dioxide from emissions.

Loneliness as a Bridge Between Anxiety, Depression, and Suicidal Thinking

In a study of over 62,000 participants, loneliness partially accounted for the link between anxiety or depressive symptoms and suicidal ideation. Tackling loneliness directly may offer a way to interrupt the progression toward suicidal thinking that cuts across diagnostic categories.

Arsenic and Cadmium Behave Opposite Ways in Soil. A New Material Handles Both.

A novel biochar engineered with sulfur and iron can simultaneously lock down arsenic and cadmium in contaminated agricultural soils - two pollutants with opposing chemical behavior that have resisted joint remediation until now. Field trials show bioavailable cadmium cut by 41% and arsenic by 64%.

Biochar Cuts Nitrous Oxide in Upland Soils but Amplifies It in Rice Paddies - Same Material, Opposite Effects

A new study shows biochar reduces nitrous oxide emissions more effectively than lime in acidic upland soils, but increases them significantly in flooded rice paddies - with the difference traced to distinct microbial pathways activated by soil water content.

Social Media Exposure to Muscle-Building Content Tied to Steroid Use Intentions in Men

A survey of 1,515 boys and men found that social media use - particularly exposure to content promoting muscular ideals and muscle-building drugs, and engagement in body comparisons - was more strongly associated with intentions to use anabolic-androgenic steroids than raw screen time. Researchers say media literacy and marketing regulation deserve attention alongside general screen time guidance.

Surplus Construction Soil Can Replace Conventional Fill in Wind-Resistant Foundations

Engineers at Shibaura Institute of Technology tested 35 model-scale configurations of a composite pile system that uses surplus construction soil as structural fill, finding uplift capacities matching or exceeding conventional steel piles when soil compaction is maintained. A 20% drop in soil density caused roughly 50% reduction in uplift capacity -- making compaction control the critical construction variable.

Columbia Engineers Redesign the Electrolyte to Make Anode-Free Batteries Viable

Columbia Engineering researchers developed a gel polymer electrolyte with a salt-phobic polymer network that reorganizes lithium ion solvation at the nanoscale. Anode-free pouch cells using the material retained over 80% capacity after hundreds of demanding cycles and survived aggressive drilling without thermal runaway - a failure mode that destroys conventional liquid electrolyte cells.
