Scientists Say This Common Sweetener May Be Quietly Rewiring Your Metabolism
A review in Nature Metabolism argues that fructose functions as a distinct metabolic signal rather than a simple calorie source. The authors show that fructose bypasses key regulatory steps, driving de novo lipogenesis, lowering cellular ATP and fostering fat storage. Both added sugars—table sugar and high‑fructose corn syrup—deliver this risk, and the body can also generate fructose internally, widening its impact. The findings arrive amid rising global obesity and diabetes rates, prompting calls for revised dietary guidance.
Hantavirus Detected on Ship: Risk Remains Unclear
Why the "mildly" is irrelevant here: -we were simply watching for if any other passengers tested positive; not the viral load -the important part of the result is that *the test showed another passenger has hantavirus*. That means people still getting sick...
The Testes Are Highly Microvascularized: Acute COVID Can Damage the Testes, Long COVID-Spike Exposure May Slowly Damage Them Reducing Male...
Recent research highlights that the testes’ dense microvascular network makes them especially susceptible to damage from acute COVID‑19 infection and possibly lingering spike‑protein exposure. A 2024 ultrasound study of 875 men showed that higher ultrasonic microvascular density (UMVD) and testicular...
