A new substance could improve the treatment of persistent cancers. Researchers at Martin Luther University Halle-Wittenberg (MLU) and the University of Greifswald have developed a new inhibitor that makes drug-resistant tumour cells respond again to chemotherapy. The new substance blocks a protein in the cancer cells that normally transports the cancer drugs back out of the cells. The results were published in the scientific journal Molecules.

In addition to radiation therapy, cytotoxic agents, also known as chemotherapy, are frequently used to treat cancer. They prevent cells from dividing and thus cancer cells are unable to multiply unchecked...

North Carolina State University engineers continue to improve the efficiency of a flexible device worn on the wrist that harvests heat energy from the human body to monitor health.

In a paper published in npj Flexible Electronics, the NC State researchers report significant enhancements in preventing heat leakage in the flexible body heat harvester they first reported in 2017 and updated in 2020. The harvesters use heat energy from the human body to power wearable technologies — think of smart watches that measure your heart rate, blood oxygen, glucose and other health parameters — that never need to have their batteries recharged...

Scientists have developed a method that can determine an organism’s biological age with unprecedented precision. Researchers expect new insights into how the environment, nutrition, and therapies influence the aging process.

Using the model organism Caenorhabditis elegans, researchers at the University of Cologne have developed an ‘aging clock’ that reads the biological age of an organism directly from its gene expression, the transcriptome...

Studies representing nearly 2 million adults worldwide show that eating about five daily servings of fruits and vegetables, in which 2 are fruits and 3 are vegetables, is likely the optimal amount for a longer life, according to new research published today in the American Heart Association’s flagship journal Circulation.

Diets rich in fruits and vegetables help reduce risk for numerous chronic health conditions that are leading causes of death, including cardiovascular disease and cancer. Yet, only about one in 10 adults eat enough fruits or vegetables, according to the U.S. Centers for Disease Control and Prevention.

“While groups like the American Heart Association recommend four to five servings each of fruits and vegetables daily, consumers likely get inconsistent messages ...
