How will astronauts keep in shape for extended periods?

more »
Run far or run fast? That is one of the questions NASA is trying to answer with one of its latest studies -- and the answers may help keep us in shape on Earth, as well as in space. Even with regular exercise, astronauts who spend an extended period of time in space experience muscle weakening, bone loss, and decreased cardiovascular conditioning.

Printing 3-D graphene structures for tissue engineering

more »
Ever since single-layer graphene burst onto the science scene in 2004, the possibilities for the promising material have seemed nearly endless. With its high electrical conductivity, ability to store energy, and ultra-strong and lightweight structure, graphene has potential for many applications in electronics, energy, the environment, and even medicine. Now a new ink formulation has been created that allows for the 3-D printing of large, robust graphene structures with unique mechanical and biological properties.

Iguazu Falls, Argentina (June 9, 2014): Authorities were forced to close down the iconic Iguazu National Park for several days after heavy rainfall in the region caused the Parana, the river feeding into the falls, to flood. The tourist walkways and viewpoints that normally give way to breathtaking views of the falls were almost completely submerged. | (REUTERS/Raul Puentes)



Ha Long Bay, Vietnam (Sept. 8, 2014): The bay's more than 1,600 limestone islands and islets are largely uninhabited. | (REUTERS/Kham)


Pilbara region, Western Australia (Dec. 2, 2013): The Pilbara region, which is the size of Spain, has the world's largest known deposits of iron ore — it supplies nearly 45 percent of global trade in the mineral. Here, we see dried-up rivers in the region. (REUTERS/David Gray)

Ants use jaws to catapult themselves out of death traps

Science Focus

original post »

The trap-jaw ant has a won notorious reputation in the insect kingdom for its super-strong, spring-loaded mandibles, which it uses to crush prey with ease and defend its nests.

However, a new study, reported in PLOS ONE, has revealed a whole new use for its impressive jaws: flinging itself out of "death traps" set by predators.

Research carried out by Fredrick Larabee and Andrew Suarez, entomologists from the University of Illinois at Urbana-Champaign, compounds earlier findings from 2006, which showed that trap-jaw ants could use their lightning-fast mouths for "ballistic jaw propulsion"—in short, opening their jaws to 180 degrees before snapping them shut at 140 miles per hour.

The Rose Galaxies, Arp 273 Square Sticker

Here's a great sheet of stickers featuring a beautiful image from deep space


tagged with: envelope sealers, trgarp, breathtaking hubble space photos, rose galaxy, interacting spiral galaxies, amazing astronomy images, arp 273, star forming activity, new born stars, star nursery, hot young stars

Galaxies, Stars and Nebulae series An amazing outer space picture featuring two interacting galaxies that together form the shape of a rose. The larger of the spiral galaxies, UGC 1810, has a disk that is twisted by the gravitational pull of its companion galaxy, UGC 1813.
Knots of young, hot blue stars bejewel the spirals arms in glistening starlight while below, its smaller, nearly edge-on companion is going through intense star formation at its centre, perhaps triggered by their encounter.
