GMO pictures may reinforce existing views, deepening the divide of attitudes towards them‎

Images have long played a powerful role in shaping public perceptions of genetically modified organisms (GMOs), often reinforcing emotional reactions more than scientific understanding. A new experimental study published in the Journal of Science Communication (JCOM) explores how different types of images can influence people's attitudes toward GMOs—and suggests that pictures may reinforce existing views, further polarizing them.

New method rapidly analyzes cell proteins and metabolites‎

Researchers at Cedars-Sinai have developed a fast, new technique for analyzing cells, described in the journal Angewandte Chemie. The approach, called single-injection multi-omics analysis by direct infusion (SMAD), can detect more than 1,300 proteins and more than 9,000 molecular features from a single sample in less than five minutes.

How an eye physician who translated classical Greek medicine into Arabic helped form Western medical thought‎

A medieval ophthalmologist who translated Greek works by Galen, Hippocrates, and Plato into Arabic played a pivotal role in shaping Western medical scholarship, according to a study published in the journal Cogent Arts and Humanities.

By age 7, most children quickly spot individuals' social biases toward social groups, study finds‎

Most elementary school-aged children have a surprising cognitive ability: they can detect—nearly as well as adults—when someone treats people from one social group differently than another. The study, "Children's and adults' detection of social biases," published in Child Development, demonstrates children's emerging capacity to recognize and reason about social bias.

3D-printed 'spanlastics' could change how cancer drugs reach tumors‎

University of Mississippi research offers hope that cancer drug therapies packaged in 3D-printed carriers could deliver medication directly to tumors while reducing many of the side effects that cancer patients endure. In a study published in Pharmaceutical Research, the Ole Miss team demonstrated that 3D-printed spanlastics—a tiny carrier filled with cancer-fighting drugs—could be implanted directly at the site of a tumor and kill those cells.

Study finds 70% of remediated Los Angeles yards still exceed lead limit‎

Even after one of the largest environmental remediation efforts in California history, dangerous levels of lead persist in residential neighborhoods surrounding a former battery smelter in Southeast Los Angeles, according to a new study from the University of California, Irvine's Joe C. Wen School of Population & Public Health. The research is published in the journal Environmental Science & Technology. The findings reveal a serious public health failure while also highlighting the power of community-driven research to hold institutions accountable and drive meaningful change.

Review details photocatalyst–biocatalyst systems for semi-artificial photosynthesis‎

A new review from Osaka Metropolitan University (OMU) summarizes the biocatalysts involved in semi-artificial photosynthesis, an exciting research field that combines natural photosynthesis with artificial technology to efficiently generate fuels and useful substances from sunlight. The review is published in Chemical Reviews.

Global warming may be a boon for this aggressive prairie plant‎

Climate change may reduce yields of crops like corn and soybeans, but it can also give some plants an edge. That's one of the takeaways of a recent study of tall goldenrod, a common wildflower that runs rampant in fields across its native range in North America and other parts of the world where it has been introduced.

Water-repelling surfaces reveal surprising charging effects‎

Materials that repel water are used in countless applications, including industrial separation processes, routine laboratory pipetting, and medical devices. When water touches these surfaces, the interface where they meet tends to acquire a small electrical charge—an effect that is ubiquitous, yet poorly understood. KAUST researchers have now studied this in detail and their findings could have broad implications. The findings are published in the journal Langmuir.

Improving air temperature forecasts one to five weeks in advance without new model simulations‎

Researchers at the Institute of Industrial Science, The University of Tokyo and George Mason University's College of Science have developed a new method that improves air temperature forecasts one to five weeks in advance—without requiring additional model simulations. The methodology, detailed in the Proceedings of the National Academy of Sciences, provides a dual benefit, not requiring significant increase in computational cost while improving predictions.
