Can sitting cancel out the benefits of exercise?
You've probably heard the trendy phrase that "sitting is the new smoking."

Study finds many American women unaware of risk for heart disease
Heart disease kills more American women than cancer, yet many don't discuss the dangers with their doctors. A new report found that 74 percent of women reported having at least one risk factor for heart disease, but only 16 percent were told by their doctor that they were at risk. Mireya Villarreal reports.

On the generation of solar spicules and Alfvenic waves

In the lower solar atmosphere, the chromosphere is permeated by jets known as spicules, in which plasma is propelled at speeds of 50 to 150 kilometers per second into the corona. The origin of the spicules is poorly understood, although they are expected to play a role in heating the million-degree corona and are associated with Alfvénic waves that help drive the solar wind. We compare magnetohydrodynamic simulations of spicules with observations from the Interface Region Imaging Spectrog...

Local protein kinase A action proceeds through intact holoenzymes

Hormones can transmit signals through adenosine 3',5'-monophosphate (cAMP) to precise intracellular locations. The fidelity of these responses relies on the activation of localized protein kinase A (PKA) holoenzymes. Association of PKA regulatory type II (RII) subunits with A-kinase–anchoring proteins (AKAPs) confers location, and catalytic (C) subunits phosphorylate substrates. Single-particle electron microscopy demonstrated that AKAP79 constrains RII-C subassemblies within 150 to 250 an...

An environment-dependent transcriptional network specifies human microglia id...

Microglia play essential roles in central nervous system (CNS) homeostasis and influence diverse aspects of neuronal function. However, the transcriptional mechanisms that specify human microglia phenotypes are largely unknown. We examined the transcriptomes and epigenetic landscapes of human microglia isolated from surgically resected brain tissue ex vivo and after transition to an in vitro environment. Transfer to a tissue culture environment resulted in rapid and extensive down-regulation of ...
