Researchers here note that reduction in the calorie content in the diet is the important trigger for the benefits of calorie restriction, not reductions in the quantity of food ingested. The practice of calorie restriction, reducing calorie intake while still obtaining optimal micronutrient intake, has been shown to extend life […]

Malignant tumors can enhance their ability to survive and spread by suppressing antitumor immune cells in their vicinity, but a study led by researchers at Weill Cornell Medicine and NewYork-Presbyterian has uncovered a new way to counter this immunosuppressive effect. In the study, published in Nature Cancer, the researchers identified […]

The chemical steps in an important cellular modification process that adds a chemical tag to some RNAs have been revealed in a new study. Interfering with this process in humans can lead to neuronal diseases, diabetes, and cancers. A research team, led by chemists at Penn State, has imaged a […]

Using a virus that grows in black-eyed pea plants, nanoengineers at the University of California San Diego developed a new treatment that could keep metastatic cancers at bay from the lungs. The treatment not only slowed tumor growth in the lungs of mice with either metastatic breast cancer or melanoma, […]

In mouse studies, single-cell whole brain imaging found methamphetamines, cocaine and nicotine all changed neural networks — a key to developing addiction treatments Addictive psychostimulants, from nicotine in cigarettes to illicit drugs like methamphetamine and cocaine, affect different regions of the brain. The same is believed true during withdrawal; finding […]

Loss of hair cells in the inner ear is thought to be the primary mechanism behind the progression of age-related hearing loss, though there is some debate over whether it is in fact loss of cells versus loss of the connections that link hair cells to the brain. For some […]

Rejuvenation takes place very early in embryonic development. The germline cells that go into the creation of an embryo are well protected and maintained in comparison to the average somatic cell in the adult body. Nonetheless, there is an accumulation of age-related epigenetic changes and molecular damage. Cells purge themselves […]
