UNIVERSITY PARK, Pa. — Biomaterials are specifically engineered to support tissue, nerve and muscle regeneration across the body, yet physicians and researchers have limited control over the size and connectivity of the internal pores that transfer oxygen and vital nutrients to where they are most needed. To solve this problem and better support tissue regeneration, a team at Penn State has designed a new class of tunable biomaterials. Led by corresponding author Amir Sheikhi, the Dorothy Foehr Huck and J. Lloyd Huck Early Career Chair in Biomaterials and Regenerative Engineering and associate professor of chemical engineering, the team developed a highly ...

VANCOUVER - March 8, 2026 - Learning French, reading the latest Andy Weir novel, hanging out with friends for St. Patrick’s Day — language is central to all these everyday activities. Seemingly effortless from childhood, language, it turns out, is quite complex, not constrained to one set of genes or one region in the brain. Cognitive neuroscientists are now using a diverse arsenal of tools, including novel genetic analyses and AI, to gain insights into both healthy and disordered communication across individuals. “We still tend ...

Researchers have developed a microscopic 3D-printed optical device that can efficiently combine light from dozens of small semiconductor lasers into a single multimode optical fiber with very low loss. The team demonstrated photonic lanterns that multiplex 7, 19, and 37 multimode VCSEL lasers directly into a fiber while preserving brightness and easing alignment constraints. By enabling scalable incoherent beam combining of many multimode lasers, the technology could simplify and improve high-power laser systems, optical communications, and other ...

Analysis of a large, nationally representative survey shows that stroke survivors under age 50 have more problems concentrating and running errands and experience more poor mental health days than older stroke survivors do. Younger survivors who were not working faced the greatest challenges in their recovery. The study comes as stroke rates among younger people have increased rapidly in recent years, driven in part by sedentary lifestyles and rising obesity rates. The researchers behind the study say that ...

The use of artificial intelligence (AI) tools, spearheaded by generative AI, is expanding into various spheres of society, including the labour market. A study conducted by the Universitat Oberta de Catalunya (UOC) and published as open access has examined the occupational health and safety implications of this technology. "Artificial intelligence is already making decisions that directly affect the way we work and how we feel at work, often without adequate consideration of the consequences for people," said Xavier Baraza, dean of the UOC's Faculty ...

New analysis of ancient parrot DNA has revealed vibrant Amazonian parrots were transported alive across the Andes to coastal Peru centuries before the Inca Empire, highlighting a sophisticated pre-Inca, long-distance trade network spanning rainforest, highlands and deserts.  The international team of researchers, including scientists from The Australian National University (ANU), analysed parrot feathers that were discovered at Pachacamac, Peru – one of the preeminent religious centres of the Andean civilisation – ...

WASHINGTON, March 10, 2026 — No two snowflakes may be the same, but models that fail to take these variations into consideration often fall short when calculating the way snow accumulates on roofs. In Physics of Fluids, by AIP Publishing, researchers from Harbin Institute of Technology in China modeled the way snow gathers on a roof based on snowflake size and distribution. “In cold regions, snow load is a critical factor in structural design,” said author Qingwen Zhang. “However, traditional models often simplify snow as a uniform material with a single particle size, overlooking the natural heterogeneity of snowflake sizes and distributions.” This simplification ...

WASHINGTON, March 10, 2026 — Due to climate change, plants’ pollination season has been growing longer and longer. As a result, people are exposed to allergens for extended periods each year, raising a major public health concern.

Researchers at the University of Michigan have discovered that the constant gnawing of rodents isn't just a reflex or a consequence of a tough diet. It also triggers a release of dopamine in the brain—which acts as a biochemical reward or incentive—through a newly identified neural circuit. Although the circuit was discovered in mice, it could also be at work in other mammals, the researchers said, adding to a growing body of evidence that there's a deeper connection between our brains and our oral health and habits. "In the old point of view, everyone sort of believed that gnawing was ...

Researchers at the University of California San Diego have uncovered how a single protein triggers two opposite responses in blood vessels — one inflammatory and one protective. This protein, a cell-surface receptor called protease-activated receptor-1 (PAR1), plays a critical role in maintaining the structural integrity of our blood vessels. Understanding how PAR1 switches between healing and harmful signaling pathways could pave the way for new treatments for conditions marked by vascular inflammation and leakage, including sepsis, heart attack and stroke. PAR1 sits on the surface of the thin layer of cells lining blood vessels ...

“In complex cross-media environments, existing attachment mechanisms face significant physical constraints,” said Junzhi Yu, corresponding author and Professor at Peking University. “Traditional suction cups easily fail underwater due to fluid washing, or they lose their vacuum seal on rough surfaces. We needed a unified mechanism that could break through the dual barriers of environmental media and surface morphology.” To achieve this, the team looked to the lamprey. The ...

“Domain bias caused by individual differences and device variations severely limits BCI’s practical application, while existing methods struggle with feature decoupling and noise sensitivity,” explained study corresponding author Jing Jin from East China University of Science and Technology. The core innovations include (a) a fixed structure decoupler to separate category-related and independent features; (b) fine-grained patch coding and gated channel attention for spatiotemporal feature extraction; and (c) an Interclass Prototype Network (IPN) to enhance feature discriminability. “This hybrid approach enables the model to learn robust domain-invariant ...

Myocardial ischemia, the primary driver of heart attacks, remains the leading cause of death and disability worldwide. Delays in diagnosis directly correlate with increased myocardial necrosis, higher complication rates, and elevated mortality. While traditional 12-lead ECG is the clinical gold standard for ischemia detection, its episodic nature fails to capture transient, unpredictable ischemic episodes during continuous ambulatory monitoring. Though wearable ECG devices have excelled at detecting arrhythmias like atrial fibrillation (with over 95% sensitivity), their utility ...
