Only human -- the biggest risk factor in long-term space missions - Toinen muistutus siitä miksi ihmistä täytyy kosmoformata.
Here are some of the health hazards facing any future team of astronauts sent to Mars:
- PSYCHOLOGICAL STRESS: Loneliness, depression, anxiety, claustrophobia, boredom, personality conflicts within the crew.
- EMERGENCIES: Anything from motion sickness and impaired coordination to toothache and appendicitis.
- RADIATION: High-speed particles in space can slice human DNA, boosting the risk of cancer.
- MUSCULAR ATROPHY: Need for a strict exercise regime to overcome loss of muscle tone due to zero gravity.
- BONE DEMINERALISATION: Bones become more porous, thus weaker, in long-duration space missions.

In an era when a few cosmetic tweaks can elevate a handbag into a high-priced fetish, it’s no surprise that demand for designer cats—especially those that bring a whiff of wilderness to the suburbs—is booming. Current popular felines include the Savannah (part house cat, part African serval) and the Chausie (a house cat bred with a jungle cat). But until now, no professional breeder has tried to capture the mystique or allure of a tiger in a sofa-friendly form.
