For decades, the relationship between fat and cancer has been treated as a question of quantity: Eat less fat, reduce your risk of developing cancer. But new research published April 29 in Cancer Discovery shows that for pancreatic cancer, the type of fat you consume matters more than the amount.

“It’s really the type of fat that you’re consuming, not just total fat content,” says Christian Felipe Ruiz, Ph.D., an associate research scientist in YSM’s Department of Genetics and lead author of the study. “Depending on the type of fat that you consume, it can go completely different ways. We found that some fats promote cancer, as we would expect, while other fats are really good at suppressing cancer.”

One fat in particular—oleic acid, the primary fatty acid in olive oil—may be ac...

A research team led by Prof. Jerald Yoo from the Department of Electrical and Computer Engineering at Seoul National University (SNU) has developed a skin-conformal wearable health care system, “SkinECG,” capable of measuring electrocardiogram (ECG) signals without a battery. By combining energy harvesting with human body–coupled power transfer, the study presents a new solution to one of the most critical challenges in wearable devices: power supply.

The findings are published in Science Advances.

Wearable health care systems are emerging as next-generation medical technologies that enable real-time monitoring of physiological signals through body-worn sensors, allowing early ...

Scientists have developed a way to turn the body’s own immune cells into cancer-fighting agents—without removing them from the body—by using red blood cells to deliver genetic instructions. Current CAR (chimeric antigen receptor) therapies typically involve collecting a patient’s T cells, genetically modifying them in the laboratory, and then reinfusing them in a process that can take weeks. The new strategy aims to bypass that step.

In a study published in Science Translational Medicine, researchers at Westlake Laboratory of Life Sciences and Biomedicine in Hangzhou, China, report that they used engineered erythrocytes, or red blood cells, to carry messenger RNA—mRNA—that reprograms myeloid cells into tumor-targeting cells inside the body.

“Engi...

A new way of using umbilical cord blood for treating blood diseases could make the treatment more accessible to patients who need a stem cell transplant. A Phase II clinical trial of patients undergoing a cord blood transplant plus a stem cell product derived from pooled cord blood units showed that 27 of 28 patients (96%) with leukemias and GVHD survived at least one year and none of the patients experienced severe acute or chronic graft-versus-host disease, which are common complications of stem cell transplantation.

The results have been published in the Journal of Clinical Oncology.

“This is the first time transplant patients received cells from what amounts to nine different human beings,” said the study’s principal investigator, Filippo Milano, MD, Ph.D...
