SpaceX launches futuristic pop-up room, lands rocket at sea

SpaceX resumed station deliveries for NASA on Friday, and in a double triumph, successfully landed its booster rocket on an ocean platform for the first time.

'Marijuana receptor' might hold the key to new fertility treatments for men

Scientists have shown that a cannabinoid receptor, called 'CB2,' helps regulate the creation of sperm. Not only does this provide more evidence that marijuana can disrupt fertility in males, but it also suggests a therapeutic strategy for treating male infertility.

Is a popular painkiller hampering our ability to notice errors?

According to a new study acetaminophen could be impeding error-detection in the brain.

Clathrate ices identified in comet 67P

For decades, scientists have agreed that comets are mostly water ice, but what kind of ice -- amorphous or crystalline -- is still up for debate. Looking at data obtained by ESA's Rosetta spacecraft in the atmosphere, or coma, around comet 67P/Churyumov-Gerasimenko, scientists are seeing evidence of a crystalline form of ice called clathrates.

New microwave synthesis technique produces more-affordable hydrogen

Scientists create a molybdenum-based material that could be a low-cost alternative to platinum for splitting water to make hydrogen fuel.

How an ancient civilization conserved water

High-resolution, aerial imagery bears significance for researchers on the ground investigating how remote, ancient Maya civilizations used and conserved water.

Quantum dots enhance light-to-current conversion in layered semiconductors

Scientists combined the excellent light-harvesting properties of quantum dots with the tunable electrical conductivity of a layered tin disulfide semiconductor to produce a hybrid material that exhibited enhanced light-harvesting and energy transfer properties. The research paves the way for using these materials in optoelectronic applications such as energy-harvesting photovoltaics, light sensors, and light emitting diodes (LEDs).

Curiosity leads us to seek out unpleasant, painful outcomes

Curiosity is a powerful motivator, leading us to make important discoveries and explore the unknown. But new research shows that our curiosity is sometimes so powerful that it leads us to choose potentially painful and unpleasant outcomes that have no apparent benefits, even when we have the ability to avoid these outcomes altogether.

Protective effect of genetically modified cord blood on spinal cord injury in rats

Researchers genetically modified cord blood which managed to increase tissue sparing and numbers of regenerated axons, reduce glial scar formation and promote behavioral recovery when transplanted immediately after a rat contusion spinal cord injury.
