Scientists at Gladstone Institutes found that under low-oxygen conditions, red blood cells absorb large amounts of glucose from the bloodstream, acting as a sugar sink and lowering blood sugar, which may explain reduced diabetes risk at high altitudes; a drug mimicking this effect reversed diabetes in mice, suggesting a new therapeutic approach.
Researchers find that low oxygen at high altitude causes red blood cells to absorb large amounts of glucose from the blood, acting as a glucose sink and improving oxygen delivery. This mechanism may explain the lower diabetes prevalence at high altitudes and points to new treatments, including HypoxyStat, which mimics hypoxia to reduce blood sugar by altering red blood cell glucose handling.
Denver hosts New England as Bo Nix is out 4–6 months and Jarrett Stidham will start; Patriots coach Mike Vrabel says they’ll handle Mile High with their standard altitude prep—travel early and stay conditioned. Safety Craig Woodson notes the team is 8-0 on the road and won’t alter their approach, while Broncos fans brace for a tougher road outing and some observers wonder if New England’s confidence is justified.
Research shows that champagne's taste can be affected by storage time, altitude, and environment, with older bottles losing carbonation and altitude affecting flavor perception; drinking champagne soon after purchase is recommended for optimal taste.
A new nationwide coordinating system for studying altitude will lead to changes in the listed elevations of Colorado's 14ers and the capitol steps marker in Denver, as the study shows discrepancies in their heights. The federal government will switch to this new system in 2026, impacting mapping across the country, and the study, led by a scientist at the National Oceanic and Atmospheric Administration, has taken 15 years and will redefine the American Vertical Datum.
Rocky Mountain's 2024 Altitude has undergone a complete overhaul with new geometry, suspension layout, and frame features, transitioning from an all-mountain enduro bike to a go-fast race bike. Available in carbon or alloy frames with 29" or mixed wheels, the Altitude features adjustable geometry, in-frame storage, and clean cable routing. The bike's progressive suspension and long geometry make it ideal for high-speed riding, while the Penalty Box storage system and quiet, polished finish add to its appeal.
Researchers have discovered tiny mice, known as Punta de Vacas leaf-eared mice, living at altitudes of 6,000 meters in the Puna de Atacama, a high desert plateau in the Andes. Initially, archaeologists believed the mice had been brought to the mountaintops by ancient Inca people as sacrificial offerings. However, recent findings indicate that the mice have been able to survive and thrive in the extreme conditions on their own. Genetic analysis shows that the mice from the summits are part of the same population as those at lower elevations. Researchers are now studying the mice to understand their adaptations for high-altitude living and the reasons behind their choice to inhabit such harsh environments.
The Florida Gators are preparing for a challenging season opener against No. 14 Utah, who haven't lost at home since 2020. Despite the high altitude at Utah's stadium, the Gators have decided not to adjust their travel routine. Utah's starting quarterback, Cameron Rising, is uncertain due to a knee injury, so Florida is preparing for all possible scenarios. Gators center Kingsley Eguakun is recovering from a leg injury and remains day-to-day. Freshman receiver Eugene Wilson has impressed his teammates, and the Gators have been motivated by watching the Netflix documentary series on the Urban Meyer era.
US airlines may face delays or cancellations starting July 1st if their passenger jets haven't upgraded their altimeters to deal with 5G interference. The Federal Aviation Administration (FAA) maintains that 5G C-band signals could interfere with radio wave emitters passenger jets use to measure how far they are from the ground, which pilots rely on when landing with low visibility. Though airlines aren’t actually required to get the new equipment in place until February 2024, those passenger jets that haven’t been certified for operation around C-band 5G signals by the first of July will not be allowed to land in certain low-visibility situations.
Harvard Medical School researchers conducted a study on mice and found that restricting oxygen flow led to significantly longer lifespans. The group of mice with their oxygen restricted lived, on average, 24 weeks, compared to 16 weeks for those who experienced normal oxygen levels. The researchers noted that oxygen-restricted mice preserved neurologic function longer. The study adds to previous evidence suggesting that living at higher altitudes leads to longer life spans for humans.
