Medical Xpress / Neuron cell bodies switch gene programs to steer growing axons, study finds
A new discovery by neuroscientists at Brown University's Carney Institute for Brain Science challenges long-held beliefs in neurobiology about how neurons extend axons to reach their targets.
Medical Xpress / Cancer drug pushes mutant blood stem cells to become short-lived immune cells
The biologic drug interferon-alpha can benefit patients with blood cancers called myeloproliferative neoplasms by forcing mutant blood stem cells to become shorter-lived white blood cells, according to a study by Weill Cornell ...
Phys.org / Plans to artificially dim the sun have divided scientists—here's what they're actually arguing about
No, President Joe Biden did not engineer Hurricane Milton. No, the ice crystal contrails left behind by high-altitude aircraft are not "chemtrails" sprayed by governments to control the weather or manipulate populations. ...
Phys.org / Tracking visits to public points of interest can inform community health measures
It's not so much where people live, but where they frequently spend their time, that can provide useful information for predicting community health measures. A team led by geographers in the Penn State College of Earth and ...
