Destined to melt
2025-10-10
Glaciers are fighting back against climate change by cooling the air that touches their surfaces. But for how long? The Pellicciotti group at the Institute of Science and Technology Austria (ISTA) has compiled and re-analyzed an unprecedented dataset of on-glacier observations worldwide. Their findings, published today in Nature Climate Change, demonstrate that glaciers will likely reach the peak of their self-cooling power by the next decade before their near-surface temperatures spike up and melting accelerates.
Thomas Shaw keeps a vivid memory of this special summer day in August 2022. The postdoctoral researcher in Francesca Pellicciotti’s group at the Institute of Science ...
Attitudes, not income, drive energy savings at home
2025-10-10
Some people flip off the lights the moment they leave a room, while others rarely think twice about saving energy. According to the most comprehensive analysis of people’s sentiments toward household energy savings to date, publishing October 10 in the Cell Press journal Cell Reports Sustainability, people’s attitudes and moral sentiments about their energy usage—rather than income or knowledge of how to conserve power—determine whether they take action at home.
Domestic energy usage accounts for about a fifth of all energy consumption in the United States and European Union. Understanding what matters ...
The playbook for perfect polaritons
2025-10-10
Light is fast, but travels in long wavelengths and interacts weakly with itself. The particles that make up matter are tiny and interact strongly with each other, but move slowly. Together, the two can combine into a hybrid quasiparticle called a polariton that is part light, part matter. In a new paper published today in Chem, a team of Columbia chemists has identified how to combine matter and light to get the best of both worlds: polaritons with strong interactions and fast, wavelike flow. These distinctive behaviors can be used to power optical computers and other light-based quantum ...

GLP-1RA order fills and out-of-pocket costs by race, ethnicity, and indication
2025-10-10
About The Study: In this cohort study, 40% of orders for glucagon-like peptide-1 receptor agonists (GLP-1RAs) were not filled. Non-Hispanic Black patients and Hispanic patients were less likely to fill orders than non-Hispanic white patients, and the non-Hispanic Black and Hispanic patients who filled their orders paid lower out-of-pocket costs. Out-of-pocket differences across groups may stem from differences in insurance coverage, use of different GLP-1RAs, or different cost thresholds for forgoing GLP-1RAs.

The approach could accelerate the development of new and better treatments with more tolerable side effects than existing options.
The UVA scientists have already discovered biological indicators in the blood – “biomarkers” – that can predict the survival chances of patients with ILD. But the researchers, led by John S. Kim, MD, believe these types of biomarkers can be used for far more: The scientists are aiming to determine if biomarkers ...
How can we know when curing cancer causes myocarditis?
2025-10-10
Treatments for cancer are continuously improving, but they can still cause debilitating, even fatal, side effects. Immune checkpoint inhibitors, or ICIs, have revolutionized cancer therapy, yet their use can trigger a rare but deadly side effect that affects the heart: myocarditis. ICI-related myocarditis has a mortality of up to 40%.
The adverse side effects caused by ICIs are immune-related. The immune system becomes hyperactive and attacks tissue that is healthy, not cancerous. In ICI-related myocarditis, ...

An acoustofluidic device for sample preparation and detection of small extracellular vesicles
2025-10-10
Recent research has achieved significant advances in acoustofluidic technologies for efficient isolation and biomarker-specific detection of small extracellular vesicles (sEVs). Nevertheless, rapid and high-sensitivity analysis of low-volume clinical samples remains challenging, often requiring multi-step preprocessing and bulky instrumentation. By integrating sharp-edge microstructures with acoustically induced vortices, we enable size-selective concentration of target-bound complexes for immediate fluorescence readout. "The acoustofluidic chip leverages localized acoustic streaming to spatially separate microbead-sEV conjugates from ...

Transnational electoral participation of undocumented Mexican immigrants in the US
2025-10-10
The global increase in migration—with approximately 3.6% of the global population living as expatriates—has resulted in many countries extending external voting rights to their overseas citizens. This has prompted scholarly interest in understanding the electoral participation of immigrants in their countries of origin. However, most research has focused on the factors that drive the provision of external voting rights to expatriates rather than the extent to which these rights are exercised. Furthermore, prior research has largely overlooked the political behavior of undocumented immigrants, who constitute a significant share of the immigrant population, especially in the United ...

Freely levitating rotor spins out ultraprecise sensors for classical and quantum physics
2025-10-10
Levitation has long been pursued by stage magicians and physicists alike. For audiences, the sight of objects floating midair is wondrous. For scientists, it’s a powerful way of isolating objects from external disturbances. This is particularly useful in case of rotors, as their torque and angular momentum, used to measure gravity, gas pressure, momentum, among other phenomena in both classical and quantum physics, can be strongly influenced by friction. Freely suspending the rotor could drastically reduce these disturbances – and now, researchers from the Okinawa Institute of Science and Technology (OIST) have designed, created, and analyzed such a macroscopic device, bringing ...
‘Chinese lantern’ structure shifts into more than a dozen shapes for various applications
2025-10-10
Researchers have created a polymer “Chinese lantern” that can snap into more than a dozen curved, three-dimensional shapes by compressing or twisting the original structure. This rapid shape-shifting behavior can be controlled remotely using a magnetic field, allowing the structure to be used for a variety of applications.
The basic lantern object is made by cutting a polymer sheet into a diamond-like parallelogram shape, then cutting a row of parallel lines across the center of each sheet. This creates a row of identical ribbons that is connected by a solid ...
Towards light-controlled electronic components
2025-10-10
In the future, could our mobile phones and internet data operate using light rather than just electricity? Now, for the first time, an international research team led by CNRS researchers1 has discovered how to generate an electron gas, found for example in LED screens, by illuminating a material made up of layers of oxides2. When the light is switched off, the gas disappears. This phenomenon, which lies at the interface of optics and electronics, paves the way for numerous applications in electronics, spintronics and quantum computing. It is described in an article to be published on 10 October in the journal Nature Materials.

Tiny architects, titanic climate impact: scientists call for October 10 to become International Coccolithophore Day
2025-10-10
Smaller than a speck of dust and shaped like tiny discs, coccolithophores are microscopic ocean organisms with a big climate job. They draw carbon out of seawater, help produce oxygen, and their calcite plates sink to form chalk and limestone that preserve Earth’s climate history. Today, five European research organisations launched an initiative to make 10 October International Coccolithophore Day, highlighting their crucial role in regulating the planet’s carbon balance, producing oxygen, and sustaining the ocean ecosystems that underpin all life.
The campaign is led by the Ruđer Bošković Institute (Zagreb, Croatia), the ...
