Floating about in microgravity might seem like a blissful reprieve for the human body's weight-bearing skeleton, but when ...

Dental sealant is a thin, plastic coating painted on the chewing surfaces of teeth -- usually the back teeth-- to prevent tooth decay. Although thorough brushing and flossing can remove food ...

While health officials have long dismissed such concerns, arguing that fluoridated water is an essential public health measure to combat tooth decay, recent political and scientific developments ...

By the year 2100, the “satellite carrying capacity” of the most popular low-orbit regions could decline by 50 to 66 percent due to the impacts of these emissions, according to the study ...

Less drag therefore means extended lifetimes for space junk, which will litter sought-after regions for decades and increase the potential for collisions in orbit. The team carried out simulations ...

An atmospheric layer of special interest is the thermosphere, where the International Space Station and most satellites orbit today. When the thermosphere contracts, the decreasing density reduces ...
