In the watery inside of a cell, complex processes take place in tiny functional compartments called organelles. Energy-producing mitochondria are organelles, as is the frilly golgi apparatus, which helps to transport cellular materials. Both of these compartments are bound by thin membranes. But in the past few years, research at […]

When neurons fire an electrical impulse, they also experience a surge of calcium ions. By measuring those surges, researchers can indirectly monitor neuron activity, helping them to study the role of individual neurons in many different brain functions. One drawback to this technique is the crosstalk generated by the axons […]

Researchers at Karolinska Institutet in Sweden have now, for the first time, been able to conduct a prospective study on humans that provides novel insights into how our fat cells reduce lipid […]

Most of us know that feeling of trying to retrieve a memory that does not come right away. You might be watching a romantic comedy featuring that famous character actor who always plays the best friend and finds yourself unable to recall her name (it's Judy Greer). While memory retrieval […]

The evidence to date strongly suggests that environmental factors determine longevity for the vast majority of people. If there are significant longevity-affecting gene variants out there, then they have small and unreliable effects (APOE), or are restricted to tiny lineages (SERPINE1), or both. The overwhelming majority of contributions to longevity […]

T cells of the adaptive immune system collectively become less functional with age. The immune system as a whole becomes more inflammatory and less effectively, a state described by the terms inflammaging and immunosenescence. Researchers here note that T cells struggle to survive in the aged environment, and are as […]

In today's open access research, the authors report on the generation of a biomarker of aging from the study of proteins secreted by senescent cells. Low cost assays that map closely to biological age, the burden of damage, are a potentially useful tool for research and development of rejuvenation therapies. […]

Chimeric antigen receptor (CAR) T cell therapies target specific surface features on other cells by providing T cells with a way to recognize that feature – the CAR. T cells so equipped will selectively destroy other cells with the target surface feature. To produce a CAR T cell therapy, a […]

In a new study, a computer algorithm improved the accuracy and efficiency of cervical cancer screening compared with cytology (Pap test), the current standard for follow-up of women who test positive with primary human papillomavirus (HPV) screening. The new approach uses artificial intelligence (AI) to automate dual-stain evaluation and has […]

University of Alberta engineering researchers have characterized the potentially hazardous particles in cannabis smoke and have raised awareness about their potential health effects. “It's not out of line to say there's a potential health risk in marijuana smoke, and there's not nearly enough research,” said Robert Nishida, a U of […]

Heart muscle cells made from stem cells could be used to screen drugs or develop cell-based therapies for heart disease. But these cells, called cardiomyocytes, are often immature, disorganized, and unable to behave together like working muscle tissue. University of Wisconsin–Madison researchers have created a new way to study how […]
