From the article by Julia Zorthian at Time Magazine: For the human body, Kelly said space travel has "permanent effects we simply do not fully understand" Astronaut Scott Kelly, back from his year in space on the International Space Station, said the “permanent effects we simply do not fully understand” that astronauts experience in space must [...]

From the article by Jeff Kluger at Time Magazine: Everything's different in zero-g You may or may not want to go to space, but here’s something certain: you definitely don’t want to get sick there.

From New Scientist: It’s one of the most controlled places on the planet. At Australia’s newest nanoscience centre, the air is 100 times cleaner than a sterile surgical operating theatre, and even the slightest vibrations from passing trucks or radio waves are completely blocked out. The Sydney Nanoscience Hub will allow scientists to zoom in [...]

From Chemical and Engineering News: Experts debate controversial paper that suggests delivery efficiencies for cancer nanomedicines are low and not improving. Cancer drugs don’t discriminate. They kill all cells, not just the cancerous ones. So drugmakers often look for ways to minimize how much of a chemotherapy drug ends up in healthy tissue while still [...]

From The Irish Times: Good security is all about vigilance. Your body’s immune system scrutinises all newcomers to weed out whatever looks suspicious and checking and rechecking ID. In University College Dublin, Prof Ken Dawson is developing a new approach to targeting cancer, one based on using “nano” drugs that can pass repeated checks by [...]
