On Friday, SpaceX was testing a reusable Falcon 9 rocket in Texas. But the rocket self-destructed shortly after launch.
- Astronomers find traces of one of the universe's first stars
Chemical signals found in a halo of gas surrounding our galaxy suggest the presence of remains of a massive star dating to the early universe.
How did the hummingbird get its sweet tooth? Scientists unravel mystery.Like all other birds, hummingbirds lack sweet-taste receptors. Now, science can explain how this tiny bird got its taste for nectar.
Global warming's 'pause': Where did the heat go?New research suggests that a climate cycle in the North Atlantic Ocean has absorbed the Earth's 'extra' heat, contributing to a perceived hiatus for global warming.
US drought has literally raised the ground, say scientistsGPS measurements reveal that between 2003 and 2014, land surface in the Western US has risen about 0.15 inches, a result of some 240 gigatons of water having been lost.
- Corals, fish can sniff out a bad neighborhood, say scientists
Corals and fish are able to detect chemicals in the water that signal a sickly ecosystem, suggests new research.
Did humans wipe out the Neanderthals? Maybe not.Neanderthals and modern humans coexisted for thousands of years, leaving species ample time to swap culture and DNA, finds new research.
Telescope captures spectacular view of nebula, star clusterThe European Southern Observatory's La Silla Observatory in Chile snapped the star cluster NGC 3603 and NGC 3576 nebula lighting up the southern Milky Way.
- Paleo-escargot? Humans living 30,000 years ago dined on snails, say archaeologists.
Burnt snail shells at an archeological site in Spain suggests that paleolithic people on the Iberian Peninsula harvested and ate the mollusks, say scientists.
- Why NASA wants to put rats on the space station
The US space agency is drafting plans to launch a crew of rats to the International Space Station to study how the animals adapt to life in orbit.
Is there really plankton clinging to the outside of the space station?A Russian official says that cosmonauts have collected evidence of sea plankton on the outside of the International Space Station.
Microbes thrive below Antarctic ice. A hint of life elsewhere in solar system?The discovery of bacteria in an ice-bound lake bolsters the case that similar life could exist elsewhere in the solar system. But on Earth, the find raises the prospect that Antarctic melting will release greenhouse gases.
Progress WatchWhite House could announce world's largest marine reserve soonIf the Pacific Remote Islands Marine National Monument becomes a marine reserve, it would double the area globally subject to tight fishing restrictions. Other countries are also working to expand the area of such ocean havens.
Iceland's Bardarbunga volcano rumblings prompt orange alertWhen Iceland's Grimsvötn volcano became active in April 2011, its explosive eruption sent ash plumes into the sky, disrupting flights in northwestern Europe for three days. Bardarbunga is another under-ice volcano.
Strange, clawed, lonely worm fossil finds family tree at lastThe finding is surprising because it rewrites the evolutionary history of spiders, insects and crustaceans, said study researcher Javier Ortega-Hernandez, a paleobiologist at the University of Cambridge.
Octopuses' color-changing skin inspires new type of camouflageResearchers developed flexible sheets of light sensors, containing a temperature-sensitive dye, that can automatically sense and adapt to the color of their surroundings.
Ancient flying pterosaurs lived all around the world, had no teethFossil records show that pterosaurs were likely the first airborne vertebrates and they took to the skies around 220 million years ago.
Iceland raises alert level, warning of possible volcanic eruptionThe warning comes amid swarms of earthquakes that have taken place since Saturday in Bardabunga — a subglacial stratovolcano located under Iceland's largest glacier.
Do black holes come in 'medium'? They do now.Scientists report the most precise measure yet confirming the existence of an intermediate-mass black hole, which could have played a key role in the early evolution of galaxies.
Tiny cube satellite launched by hand: Nano, nano?A Peruvian nanosatellite was launched during a spacewalk from the International Space Station Monday. The baby satellite will measure temperature and pressure and take pictures.
