Satellite imagery and machine learning used for the mapping of six seminatural open wetland types and land-use disturbance in European countries shows that wetlands are highly fragmented and have uneven restoration needs.
A molten salt, high-pressure synthesis method enables solution-based production of diverse refractory metal nitride nanocrystals, expanding access to technologically important nitride materials for advanced applications.
Gatos têm uma reputação não muito positiva. Aqui vai mais um sinal que talvez reforce isso: cientistas estão começando a achar que até mesmo um comportamento aparentemente inocente -lamber outro gato- pode não ser sempre algo gentil.

Until about 60,000 years ago, diminutive hominin cousins, Homo floresiensis (affectionately nicknamed Hobbits for obvious reasons), shared the island of Flores with Komodo dragons, pygmy elephants, and giant rats.
Based on the presence of hominin and pygmy elephant bones in the same layers of cave sediment, it originally looked like the Hobbits had hunted and butchered dwarf elephants—an impressive feat for such a tiny hominin. But according to University of Tübingen anthropologist Elizabeth Veatch and her colleagues, it was the Komodo dragons that were the hunters, while the Hobbits only showed up to scavenge what was left.
If Veatch and her colleagues are right, their findings may challenge some of the assumptions we’ve made about Homo floresiensis—and about which hominin species was the first to venture into the wider world beyond Africa.

Miller, Christian D. Lorenz, John R. Varcoe, Sandrine Lyonnard, Fabrizia Foglia We combine neutron spectroscopy, total scattering, and MD simulation to expose the structure–transport relationships driving ionic mobility, proving conductivity under confinement emerges from collective ion–water–polymer dynamics.

By integrating reinforcement learning with quantum error correction, a quantum computer continuously self-calibrates during computation, achieving record logical error rates and enhanced resilience to drift.
Radio-frequency switches made from two-dimensional layered hexagonal boron nitride (hBN) were co-integrated on gallium nitride (GaN) microchips to build programmable millimetre-wave (mmWave) monolithic microwave integrated circuits suitable for 6G hardware.
Viscoelastic phase separation is used to fabricate non-collapsible, air-rich networks in high-water-content hydrogels containing silica aerogel beads, allowing air to permeate through the material and enabling a tenfold increase in oxygen permeability over pristine hydrogels.
The insects could explore underwater for up to three hours. Plus, fake cancer studies rake in the citations and how scientists can build trust by recognizing their biases.
This Perspective examines the challenges and opportunities of genomic sequencing across multiple clinical applications, including genetic therapies, and calls for the establishment of new, centralized reference standards to improve consistency and accuracy in the field of precision medicine.
SyeA was present in the Buchnera ancestor, is secreted into the host cytoplasm, is homologous to secreted effectors of bacterial pathogens and is essential for Buchnera transmission.
An immunopeptidomics analysis identifies numerous Plasmodium T cell antigens that are conserved across malaria parasite species and expressed at several phases of the parasite’s life cycle, with possible applications in the development of a malaria vaccine.
Researchers at the Massachusetts Institute of Technology (MIT) have developed an ultra-efficient computer chip that could help tiny robots and lightweight devices create detailed 3D maps of their surroundings while using very little energy. The new chip could allow small drones to fly through narrow spaces, such as air-conditioning ducts or industrial pipelines, to inspect […]
Chronic dietary cholesterol activates Ral GTPases, which promote LDLR internalization and lysosomal degradation through RalBP1–REPS1 and CTSA, thereby reducing cholesterol clearance, whereas CTSA inhibition restores LDLR function and may offer a therapeutic strategy for cardiovascular disease.
Global high-resolution mapping shows widespread seagrass loss and degradation since 2019, with most meadows outside protected areas, highlighting urgent conservation and climate-policy needs.
