Cell aging can be slowed by oxidants

At high concentrations, reactive oxygen species—known as oxidants—are harmful to cells in all organisms and have been linked to aging. But a study from Chalmers University of Technology, Sweden, has now shown that low ...

Lighting the way to selective membrane imaging

Researchers at Kanazawa University monitored the emission of blue-green light from water-soluble tetraphenylethene molecules adsorbed at a phospholipid-adsorbed liquid-liquid interface made to resemble a biomembrane. They ...

New analysis method can lead to better cancer drugs

While proteins on the surfaces of cells are the targets for most drugs, refined methods are needed to analyze how these membrane proteins are organized. Researchers at Karolinska Institutet have developed a new DNA-based ...

Truncated immune system receptors may regulate cellular activity

MIT Media Lab researchers have discovered that shortened versions of immunity-related protein receptors, long written off as incomplete and therefore nonfunctional, can bind with their natural counterparts on the cell membrane ...

Calcium bursts kill drug-resistant tumor cells

Multidrug resistance (MDR)—a process in which tumors become resistant to multiple medicines—is the main cause of failure of cancer chemotherapy. Tumor cells often acquire MDR by boosting their production of proteins that ...
