Here at UT, we've had several stories that describe the concept of a space elevator. They are designed to make it easier to get objects off Earth and into space. That, so far, has proven technically or economically infeasible, ...

As North America heats up due to climate change, animals are responding in three primary ways: moving north, heading to higher elevations and making phenological changes—adjusting annual cycles such as when they breed.

Scientists have known from ice core research that it's easier to melt an ice sheet than to freeze it up again. Now, they know at least part of the reason why, and it has to do with ice's "sponginess," according to a new study ...

An elevator (or lift in British English) is a type of vertical transport equipment that efficiently moves people or goods between floors (levels, decks) of a building, vessel or other structures. Elevators are generally powered by electric motors that either drive traction cables or counterweight systems like a hoist, or pump hydraulic fluid to raise a cylindrical piston like a jack.
Languages other than English may have loanwords based on either elevator (e.g., Korean & Japanese) or lift (e.g., Russian & Cantonese).
Because of wheelchair access laws, elevators are often a legal requirement in new multistory buildings, especially where wheelchair ramps would be impractical.
