Daily briefing: Chemical 'shuttles' carry large drugs across the blood-brain barrier
Briefly

Recent advancements have allowed for significant breakthroughs in various fields, including drug delivery to the brain using natural transport molecules. In a remarkable feat, climbers became the first to summit Mount Everest utilizing xenon gas, which aids in acclimatization and mitigates altitude sickness, highlighting the potential for shorter, less impactful climbing expeditions. Meanwhile, a key air-pollution research lab faces shutdown due to government contract changes, raising concerns about the future of public health standards derived from its findings. Lastly, new research suggests that bed bugs thrived alongside the earliest urban settlements, positioning them as the first urban pests.
"Xenon improves the acclimatisation and protects the body from altitude sickness, which makes the climb safer and shorter," says expedition organizer Lukas Furtenbach.
"We need this capability; virtually all of the air-quality standards that we have today are built around evidence from this exposure facility," states Dan Costa, a former EPA toxicologist.
"When we started to live in cities, we brought all these people together, and they all had their own bedbugs with them," explains entomologist Warren Booth.
Shorter expeditions could lower the environmental impact of such trips, says Lukas Furtenbach.
