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. In Physics of Fluids, by AIP Publishing, researchers from Embry‑Riddle Aeronautical University and two French universities, the University of Rouen Normandy and the University of Lille, developed an advanced computational model of outdoor airflow through trees.

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 ...

PULLMAN, Wash. — Research led by scientists at Washington State University has revealed insights on how plants form a microscopic landscape of proteins crucial to photosynthesis, the basis of Earth's food and energy chain. The discovery provides a new view of the molecular engine that converts sunlight into bioenergy and could enable future fine-tuning of crops for higher yields and other useful traits. Colleagues at WSU, the University of Texas at Austin, and the Weizmann Institute of Science in Israel used a novel, technology-powered approach to peer inside plant leaf cells and visualize the landscape of the photosynthetic membrane — the ribbon-like structure where plants ...

CHAMPAIGN, Ill. — Deep-sea waters are warming due to heat waves and climate change, and it could spell trouble for the oceans’ delicate chemical and biological balance. A new study, however, demonstrates that the microbe Nitrosopumilus maritimus may already be adapting well to warmer, nutrient-poor waters. Researchers predict that these surprisingly adaptable iron-dependent ammonia-oxidizing archaea will play an important role in reshaping ocean-nutrient distribution in a changing climate. The study’s findings are published in the Proceedings of the National Academy of Sciences. Nitrosopumilus ...

Does modernization—economic growth, technological advancement, globalization, increased education, and urbanization—reduce cultural differences? Conventional wisdom suggests that as nations get richer and more educated, a globalized, modern culture emerges featuring low birth rates, high divorce rates, and an overall focus on the individual. Thomas Talhelm tests this hypothesis using the World Values Survey, which has collected data in a broad range of countries since 1981. Notably, variation in values between countries in the World Values Survey has grown from 1981–2017. ...

PULLMAN, Wash. — Smoking cannabis can do more than blur memories. It can reshape them. A new Washington State University study found that people who consumed THC were more likely to recall words that were never presented and struggled with everyday tasks such as remembering to do something later. Published in the Journal of Psychopharmacology, the study is one of the most comprehensive looks yet at how cannabis affects memory. The findings suggest cannabis can impair not only simple recall, such as remembering a list of words, but also forms of memory people rely on in daily life, like remembering appointments, keeping ...

High temperatures have long been empirically linked to violence, conflict, and aggression at the societal level—a troubling pattern in a warming world. Alessandra Cassar and colleagues sought to explore the effect of high heat on individual egalitarianism, resource maximization, selfishness, spite, and competitiveness. The authors invited university students in Colombia, India, Kenya, Mexico, and the United States to play games that involved making choices about whether to share, whether to reduce another player’s payoff at a cost to oneself, as well as whether or not to compete. ...

Motor imagery (MI) is the mental process of imagining a specific limb movement, such as raising a hand or walking, without physically performing it. These imagined movements generate distinct patterns of brain activity that can be recorded using electroencephalography (EEG). By decoding these signals, researchers can enable direct communication between the brain and computers, making MI-EEG a powerful tool for applications such as motor rehabilitation and the assistive control of wheelchairs and prosthetic devices. However, EEG signals generated during MI vary significantly across individuals ...
