Grooming behavior between dairy cows reveals complex social network

Like humans, cattle are social creatures with complex relationships that change as group dynamics evolve. A study published in Frontiers in Veterinary Science offered new insights into the social networking behavior of dairy cows, building on a body of research that could someday help reshape farm management practices to create healthier living environments for the animals.

Ancient shell llama offering found in lake Titicaca

A llama carved from a spondylus shell and a cylindrical laminated gold foil object were the contents of a carved stone box—an offering—found at the bottom of Lake Titicaca, according to researchers from Penn State and the Université libre de Bruxelles, Belgium. The offering, found near an island in the lake, was not located where others had found offerings in the past.

Malignant cancer diagnosed in a dinosaur for the first time

A collaboration led by the Royal Ontario Museum (ROM) and McMaster University has led to the discovery and diagnosis of an aggressive malignant bone cancer—an osteosarcoma—for the first time ever in a dinosaur. No malignant cancers (tumours that can spread throughout the body and have severe health implications) have ever been documented in dinosaurs previously. The paper was published August 3rd in the prestigious medical journal The Lancet Oncology.

‘Worst-case’ CO2 emissions scenario is best for assessing climate risk and impacts to 2050

The RCP 8.5 CO2 emissions pathway, long considered a “worst case scenario” by the international science community, is the most appropriate for conducting assessments of climate change impacts by 2050, according to a new article published today in the Proceedings of the National Academy of Sciences. The work was authored by Woods Hole Research Center (WHRC) Risk Program Director Dr. Christopher Schwalm, Dr. Spencer Glendon, a Senior Fellow at WHRC and founder of Probable Futures, and by WHRC President Dr. Philip Duffy. Long dismissed as alarmist or misleading, the paper argues that is actually the closest approximation of both historical emissions and anticipated outcomes of current global climate policies, tracking within 1% of actual emissions.

Hydrogel paves way for biomedical breakthrough

Published in Advanced Functional Materials, a University of Sydney team of biomedical engineers has developed a plasma technology to robustly attach hydrogels—a jelly-like substance which is structurally similar to soft tissue in the human body—to polymeric materials, allowing manufactured devices to better interact with surrounding tissue.
