Scientists use Doppler to peer inside cells

Doppler radar improves lives by peeking inside air masses to predict the weather. A Purdue University team is using similar technology to look inside living cells, introducing a method to detect pathogens and treat infections ...

Patterns in primordial germ cell migration

Whenever an organism develops and forms organs, a tumor creates metastases or the immune system becomes active in inflammation, cells migrate within the body. As they do, they interact with surrounding tissues which influence ...

New data on 'jumping genes' linked to cancer

Scientists from the University of Granada and GENYO have discovered a mechanism via which our cells protect themselves against these transposable or mobile genetic elements, known as "LINE-1," which are involved in the development ...

Cancer cells 'remove blindfold' to spread

Cancer cells spread by switching on and off abilities to sense their surroundings, move, hide and grow new tumors, a new study has found.

Human white blood cells use molecular paddles to swim

Human white blood cells, known as leukocytes, swim using a newly described mechanism called molecular paddling, researchers report in the September 15th issue of Biophysical Journal. This microswimming mechanism could explain ...

Iron-mediated cancer cell activity: A new regulation mechanism

CNRS researchers at the Institut Curie have recently shown that cancer cells use a membrane protein that has been known for several decades to internalize iron. Published in Nature Chemistry, this work shows that the absorbed ...

Visualizing differences in RNA biology between single cells

A longstanding quest in medicine has been to understand how the same disease presents differently among various patients. Although it has been thought that a central aspect of these differences is a heterogeneity between ...
