Extreme bradycardia and tachycardia in the world's largest animal - PNAS: We present a major advancement in our ability to bring the physiological laboratory to the open ocean through the noninvasive use of a suction cup-attached tag equipped with surface electrodes. Our study provides heart rate data of a large, free-diving whale (blue whale) without prior capture or restraint. We recorded a wide range of heart rates from the tag, reaching only several beats per minute during deep foraging dives (bradycardia) and nearly 40 beats per minute at the sea surface (tachycardia) as the whale recovered from its oxygen debt. The latter likely represents maximal heart rate given the measured duration of the heart beat itself, thereby demonstrating the greatest dynamic range in cardiac activity at this scale. https://lnkd.in/eWmgjHF3

"Similar to what has been shown in people, aging dogs have increases in blood inflammatory markers. This indicates that aging in dogs, like people, may be accompanied by a proinflammatory state, known as inflammaging." 🐾 Check out our #blogpost to learn more about these scientific findings: https://lnkd.in/gfsiRFNC. #scientificresults #scientificresearch #dogscience #doghealth

Wisdom from our Research Institute: Aquatic exercise facilitates an increase in the cardiac output of blood throughout the body, increasing oxygen to the muscles and the central nervous system. Learn more at https://hubs.la/Q02sKnMx0

Check it out please. I talk here about the system and possible contributors underlying the bubonic plague.

Heterochronic parabiosis consists of surgically connecting the circulatory systems of a young and an old animal. For bones 🦴 the rejuvenation setting provide increase in chondrocyte proliferation, osteoblastic differentiation and subsequent matrix synthesis. Conversely, in accelerated #aging scenarios, there is an increase in #inflammation and osteoclast activity. https://lnkd.in/eGTUVP_a

2 cardinal lab-made sins on #SARCOV2 #COVID:  1. Human to Human Transmission: PRRA -- Furin Cleavage gain of function into human cells. 2. Asymptomatic Transmission: ORB-8 --Interferes with signals to show no signs of symptoms.

Researchers at Australian Red Cross Lifeblood are doing some exciting work to test ways to extend the shelf life of platelets. Currently in Australia, platelet shelf life is just seven days, but using cryopreservation and cold storage could extend the shelf life to up to two years. To explain further, Lifeblood's A/Prof Denese Marks spoke with the limbic at the recent Blood 2024 meeting: https://lnkd.in/g_h_XTrr

Our article “Spillover effects of reminder nudges in complex environments” has been published in PNAS. We show that nudges have negative spillover effects, which persist even after the removal of the nudge, while the positive effects on targeted behavior diminish. Our results hence highlight that spillover effects could change the conclusions about the effectiveness of nudges. Alex Koch and Dan Mønster https://lnkd.in/eKmeWg2Y

New research by De Napoli et al. investigates the metabolic adaptions in skeletal #muscle during #hibernation. "Reduced ATP turnover during hibernation in relaxed skeletal muscle" https://lnkd.in/gcEHzt2U Using an #AuroraScientific 1400A system, they were able to understand more about how animals achieve remarkable energy savings and maintain muscle function despite prolonged disuse. Perhaps ATP turnover does take a long winter nap!
