Glacial lakes in Alaska are expanding at an accelerating rate as glaciers melt, with rapid expansion over just six years. Research forecasts where lakes could grow or form in the future.

Biochar is widely promoted as a climate friendly soil amendment that can store carbon and improve crop growth. Yet scientists have long debated whether it always benefits soil ecosystems. A new study suggests the answer is more complex. By combining meta analysis with machine learning, researchers show that biochar can either help or harm soil organisms depending on how it is produced and applied.

A research paper by scientists from East China University of Science and Technology, University of Applied Sciences Campus Vienna, and other institutions proposed a domain generalization model (DGIFE) for electroencephalography (EEG) signals, featuring structured feature decoupling and fine-grained data augmentation to address the domain bias challenge in cross-subject brain-computer interface (BCI) applications.

The new research paper, published on Feb. 24 in the journal Cyborg and Bionic Systems, presented the development, validation, and optimization of the DGIFE model, demonstrating its superior generalization performance and noise robustness across multiple public datasets, providing an effective solution for practical BCI deployment.

As artificial intelligence (AI) rapidly integrates into clinical settings—from predicting patient outcomes to deploying humanoid "robotic nurses"—an article published in the Hastings Center Report warns that the core of nursing, its moral agency, must remain a human-driven responsibility.

A team from University of Toronto Engineering is the first to synthesize long noncoding RNA (lncRNA) outside the cell — a new approach to drug discovery that has already yielded some promising anti-inflammatory molecules. The team was inspired by advances in the field of messenger RNA (mRNA) and protein replacement therapies. They realized that a similar approach could be used to deliver lncRNA to the body, unlocking a potential new source of drugs.
