Phys.org / Ultra-thin wireless retinal implant offers hope for safely restoring vision signals
An international research team led by Prof. Dr. Sedat Nizamoğlu from the Department of Electrical and Electronics Engineering at Koç University has developed a next-generation, safe, and wireless stimulation technology ...
Phys.org / PFAS contamination in Pawcatuck River traced back to old textile mill ponds
A study led by University of Rhode Island Graduate School of Oceanography alumnus Jarod Snook, Ph.D., identified a long-term source of PFAS, or "forever chemicals," entering the Pawcatuck River from two historically contaminated ...
Phys.org / Transforming hydrogen energy by flattening granular catalysts into paper-thin sheets
Catalysts are the invisible engines of hydrogen energy, governing both hydrogen production and electricity generation. Conventional catalysts are typically fabricated in granular particle form, which is easy to synthesize ...
Medical Xpress / Wood burning in homes drives dangerous air pollution in winter, study finds
Throwing another log into a crackling fireplace on a cold winter's night might seem like a cozy, harmless tradition. But Northwestern University scientists have found residential wood burning is a major—yet often overlooked—contributor ...
Phys.org / Climate change can alter flower nectar quality and supply, threatening monarch butterfly migration
Monarch butterflies have always been remarkably resilient. Every fall, these delicate orange-and-black travelers set out on a journey so improbable it borders on myth, flying some three thousand kilometers from Canadian fields ...
Phys.org / Glassy dynamics model predicts lipid exchange rates across cell membranes
Biological processes that govern our lives are many, intertwined, and often difficult to understand. They involve countless interactions happening at once—molecules recognizing each other, signals being transmitted, and ...
Phys.org / Biologists and engineers follow goopy clues to plant-wilting bacteria
Slippery, drippy goop makes Ralstonia bacteria devastating killers of plants, causing rapid wilting in tomato, potato, and a wide range of other crops, according to new research. The work, published Jan. 22 in Proceedings ...
Phys.org / Discovery reveals how acetylation controls key enzyme linked to cancer growth
Researchers from the University of Seville have participated in research to identify the molecular details of the regulation of an enzyme essential for sugar metabolism and closely linked to cell proliferation and growth: ...
Phys.org / Refined radiocarbon dating provides clearer timeline of human activity along Cantabrian coast 18,000 years ago
A new study refines radiocarbon dating of marine remains and significantly improves the precision with which the human past of the Magdalenian period in the Cantabrian region of Spain can be reconstructed, a key phase of ...
Phys.org / Harnessing nanoscale magnetic spins to overcome the limits of conventional electronics
Researchers at Kyushu University have shown that careful engineering of materials interfaces can unlock new applications for nanoscale magnetic spins, overcoming the limits of conventional electronics. Their findings, published ...
Medical Xpress / A mechanical view on metastasis: Tumor cell viscosity found to guide key steps in cancer spread
Millions of people worldwide are diagnosed with cancer every year. In advanced tumor diseases, cancer cells detach from the original tumor and settle in other parts of the body to form metastases. On their way, they have ...
Medical Xpress / Regenerating lost lymph nodes with bioengineered tissues
The rising incidence of cancer worldwide has led to an increasing number of surgeries that involve the removal of lymph nodes. Although these procedures play a major role in cancer staging and preventing the spread of malignancies, ...
