Mechanisms of Elevated Cutaneous Vascular Tone in College-Aged Black Individuals | Hypertension BACKGROUND: Hypertension prevalence is greatest in the US non-Hispanic Black population, possibly through reduced vascular function. Although heightened cutaneous vascular tone and vasoconstrictor res...

Excited to see my final doctoral work published with @americanheart.bsky.social! We found that college-aged Black individuals had greater resting, but not evoked, cutaneous #vasoconstriction. These responses seemed reliant upon an environment greater in #oxidativestress. #academicsky

Ageing attenuates regional vasoconstriction during acute lowering of upper and lower limbs The venoarteriolar and myogenic response (VMR) is a non-adrenergic, non-baroreflex-mediated mechanism that increases local vascular resistance and contributes to blood pressure (BP) regulation during...

Excited to see our most recent publication in @expphysiol.bsky.social! We found that healthy #aging reduces the regional vasoconstrictor responses to limb lowering in both the arm and leg. This may have important implications for orthostatic #bloodpressure regulation in older adults.

This is a new image from #JWST.

The bright points with spikes are stars in the Milky Way.

Everything else is a galaxy.

Everything. Else. Is. A. Galaxy.

“Years from now, when we look back, I hope we’ll say this was the inflection point ... when we stood up for science, for truth and for each other. When we built something stronger—not in spite of the pressure, but because of it.” —APS CEO Scott Steen #APS2025 11/11🧪

#Newarticlealert from Autonomic Neuroscience! We reviewed the role of the autonomic nervous system in women's blood pressure regulation, with particular emphasis on its function with aging and presence of hypertension. The link will provide free access until May 25, 2025! #womenshealth #AcademicSky

New article alert! This study helped us dive into the effects of acute cervical vagus nerve stimulation on heart rate, blood pressure, and #MSNA both at rest and in response to static exercise. The link provided gives free access until May 20, 2025! #physiology #autonomics #AcademicSky #science

Volunteers needed for a study!! Please share with anyone who may be interested!

James Webb Space Telescope captures light show from Milky Way's black hole A black hole might conjure images of a dark, quiet void, but never-seen-before images captured by the James Webb Space Telescope reveals the centre of the Milky Way looks more like fireworks.

JWST observations of our very own black hole (the one at the centre of the Milly Way) show that its brightness changes basically all the time. A very nice ABC News article (including some quotes by me 😎) 🔭🧪 www.abc.net.au/news/science...

Despite a Judge’s Ruling, Large Swaths of NIH Funding Remain Effectively Frozen The groups that review and decide on grant proposals cannot schedule their meetings because the Trump administration has barred them from posting notices in the Federal Register.

An update on NIH funding and the loophole that's keeping it out of scientists' reach. H/T to @avaskham.bsky.social, who had it first. #HigherEd #AcademicSky
