NASA uses 3D printer to make copper rocket engine part

NASA has long wanted to use 3D printers to make parts for space missions when they are needed rather than having to carry huge amounts of spare parts to cover every possible breakage event. NASA is also looking to use 3D printers here on Earth to reduce the cost of building and maintaining rockets and other systems. NASA has used a 3D printer to make its first full-scale copper rocket engine part.

New atomic clock doesn’t lose a second for 15 billion years

New atomic clock doesn’t lose a second for 15 billion years

Physicists have invented a new atomic clock that is the most accurate clock ever invented. According to the team of scientists that have worked on the clock, it won't gain or lose a second over 15 billion years. The record setting timepiece is an optical lattice clock that uses strontium atoms and is three times more accurate than the clock that held the previous record.

NASA creates a scientific super squad to search for alien life

NASA creates a scientific super squad to search for alien life

S.H.I.E.L.D. had better watch out. NASA has just assembled the Avengers—of space scientists. Dubbed the Nexus for Exoplanet System Science (NExSS), it is a team of scientists reaching across various disciplines whose for the common goal of searching for life on distant exoplanets far outside our own solar system. NASA and the scientific community realized that although different researchers had the same goal of finding biosignatures, or life on other planets, no one was regularly communicating with scientists outside his own discipline.

Fossilized dinosaur eggs cluster found in China

Fossilized dinosaur eggs cluster found in China

Dinosaur discoveries are nothing new in China, and it has recently been the source of yet another discovery. According to state media, a total of forty three dinosaur egg fossils were discovered in a southern China region during road construction. Says the reports, the eggs are large, with one in particular measuring in at 13 centimeters in diameter. Of the forty three that were found, nineteen of them are said to be entirely intact, while the rest are broken in some way.

Vampire Squid feeds upon waste, blasts eggs

Vampire Squid feeds upon waste, blasts eggs

Today you're going to learn about a squid that's been profiled by a couple of scientists in the latest Current Biology science publication. A paper has been released, you see, on the species Vampyroteuthis infernalis. That translates roughly to Infernal Vampire Squid, or Vampire Squid from Hell. It's not a pleasant name, to be sure, but it's fitting. This creature doesn't suck blood, but it does live as close to the underworld as you're going to get, in the deep ocean, and it does eat bits and pieces of other animals. Not living animals - unless by chance - but waste, mostly.

Researchers analyze 170 year old champagne from shipwreck

Researchers analyze 170 year old champagne from shipwreck

Back in the summer of 2010, 168 bottles of champagne were discovered in a shipwreck in the Baltic Sea, about 50 meters deep and in well-preserved condition due to the protective nature of the cool and dark environment. Some of those bottles went on to be sold a year or so later, but three of them were sacrificed in the name of science, being studied in a “chemical and sensory analysis” to see what bottled champagne was like in the 1800s.

Elon Musk insists SpaceX rocket landing will work (eventually)

Elon Musk insists SpaceX rocket landing will work (eventually)

While last week's news of the Falcon 9 rocket's oh-so-close-but-not-quite landing attempt was somewhat disappointing to SpaceX fans and observers, Elon Musk isn't giving up! The SpaceX founder commented in a pair of tweets on Saturday that they had determined the rocket's crash was caused by a slower than expected throttle valve response. The latest event is part of a continued attempt by SpaceX to land a rocket on a floating platform — as opposed to crashing into the sea — in order to reuse it in future launches.

NASA’s Dawn captures most detailed pics of Ceres to date

NASA’s Dawn captures most detailed pics of Ceres to date

NASA’s Dawn spacecraft is back in dwarf planet Ceres’ sunny-side orbit after spending in excess of a month on the planet’s dark side. Now that it can see again, the spacecraft has captured a series of new pictures of the tiny planet, and they are the most detailed and highest resolution so far, having been snapped at a distance of 21,000 miles. Furthermore, the images have been aggregated into a short animation showing the planet rotate in relatively small increments.

Researchers find oldest stone tools predate modern humans

Researchers find oldest stone tools predate modern humans

The record for oldest stone tools discovered has been broken, with researchers working in Kenya finding a set of tools that are about 3.3 million years old. This eclipses stone tools that had been discovered in Ethiopia in the past, which had up until now been the oldest stone tools discovered. That’s not the most interesting part of the discovery, however — these newest old tools are older than the earliest genus Homo human fossils. The tools, then, are older than modern humans, dashing some previously held beliefs.
