Mice with fewer insulin-signaling receptors don't live longer

Scientists studying longevity thought it might be good to lack a copy of a gene, called IGF1 receptor, that is important in insulin signaling. Previous studies showed invertebrates that lacked the copy lived longer, even ...

New strategy could lead to dose reduction in X-ray imaging

For more than a century, the use of X-rays has been a prime diagnostic tool when it comes to human health. As it turns out, X-rays also are a crucial component for studying and understanding molecules, and a new approach ...

Living cells say: Can you hear me now?

It has long been known that cells release chemical signals in response to outside conditions, triggering reactions inside the cell.

Biochemical cell signals quantified for first time

Just as cell phones and computers transmit data through electronic networks, the cells of your body send and receive chemical messages through molecular pathways. The term "cell signaling" was coined more than 30 years ago ...

Researchers publish study on neuronal RNA targeting

SUNY Downstate scientist Ilham Muslimov, MD, PhD, along with senior author Henri Tiedge, PhD, professor of physiology and pharmacology and of neurology, published a study suggesting that cellular dysregulation associated ...
