The latest science news from Science Daily

Plate tectonics has shaped the Earth's surface for billions of years: Continents and oceanic crust have pushed and pulled on each other, continually rearranging the planet's façade. As two massive plates collide, one can give way and slide under the other in a process called subduction. The subducted slab then slips down through the Earth's viscous mantle, like a flat stone through a pool of honey.

Researchers have created a system called 'Interactive Robogami' that lets you design a robot in minutes, and then 3-D-print and assemble it in as little as four hours.

Photosynthesis provides energy for the vast majority of life on Earth. But chlorophyll, the green pigment that plants use to harvest sunlight, is relatively inefficient. To enable humans to capture more of the sun's energy, scientists have taught bacteria to cover themselves in tiny, highly efficient solar panels to produce useful compounds.

Imagine you're on your way to Mars, and you lose a crucial tool during a spacewalk. Not to worry, you'll simply re-enter your spacecraft and use some microorganisms to convert your urine and exhaled carbon dioxide into chemicals to make a new tool. That's one goal of scientists developing ways to make long space trips feasible.

A team of engineers has developed stretchable fuel cells that extract energy from sweat and are capable of powering electronics, such as LEDs and Bluetooth radios. The biofuel cells generate 10 times more power per surface area than any existing wearable biofuel cells. The devices could be used to power a range of wearable devices.

Baleen whales are amongst the largest animals to have ever lived and yet very little is known about their breeding habits. One researcher's second look at previously found baleen whale fossils from Japan provides new evidence of a now long-gone breeding ground of the extinct baleen whale Parietobalaena yamaokai dating back over 15 million years.

Using the most precise seafloor maps ever created of Antarctica's Ross Sea, researchers have discovered a long-dead river system that once flowed beneath Antarctica's ice and influenced how ice streams melted after Earth's last ice age.

The moon is likely very dry in its interior according to a new study analyzing fragments of the 'Rusty Rock,' a rock collected from the moon's surface during the Apollo 16 mission in 1972.

Tremendous amounts of soot, lofted into the air from global wildfires following a massive asteroid strike 66 million years ago, would have plunged Earth into darkness for nearly two years, new research finds. This would have shut down photosynthesis, drastically cooled the planet, and contributed to the mass extinction that marked the end of the age of dinosaurs.

Scientists found a gene variant that affects cholesterol levels also could increase the risk of contracting typhoid fever. A common cholesterol-lowering drug could protect animal models against Salmonella Typhi, the culprit behind the potentially deadly infection. The findings give insight into the mechanisms that govern human susceptibility to infectious disease and point to possible avenues to protect against pathogens -- like Salmonella or Ebola -- whose entry into host cells is regulated by cholesterol.
