Research roundup: 2,400-year-old clay puppets; this is your brain on Klingon

It’s a regrettable reality that there is never time to cover all the interesting scientific stories we come across each month. In the past, we’ve featured year-end roundups of cool science stories we (almost) missed. This year, we’re experimenting with a monthly collection of such stories. March’s list includes fascinating papers on such topics as how the brain responds to speaking Klingon (or Dothraki, or Navi), the discovery of creepy preclassic Salvadoran puppets, the effectiveness of “dazzle camouflage,” and how male blue-lined octopuses manage not to be cannibalized by their chosen mates. Wind Cave’s rocks fluoresce under black light Continue ReadingResearch roundup: 2,400-year-old clay puppets; this is your brain on Klingon

Hubble’s 20-year study of Uranus yields new atmospheric insights

The ice-giant planet Uranus, which travels around the sun tipped on its side, is a weird and mysterious world. Now, in an unprecedented study spanning two decades, researchers using NASA’s Hubble Space Telescope have uncovered new insights into the planet’s atmospheric composition and dynamics. This was possible only because of Hubble’s sharp resolution, spectral capabilities, and longevity.

Costa Rica’s mudball meteorite: A cosmic survivor that avoided collisions in the pinball world of asteroids

In April 2019, rare primitive meteorites fell near the town of Aguas Zarcas in northern Costa Rica. In an article published in the journal Meteoritics & Planetary Science, an international team of researchers describes the circumstances of the fall and show that mudball meteorites are not necessarily weak.

The first flight of Isar Aerospace’s Spectrum rocket lasted just 40 seconds

The first flight of Isar Aerospace’s Spectrum rocket didn’t last long on Sunday. The booster’s nine engines switched off as the rocket cartwheeled upside-down and fell a short distance from its Arctic launch pad in Norway, punctuating the abbreviated test flight with a spectacular fiery crash into the sea. If officials at Isar Aerospace were able to pick the outcome of their first test flight, it wouldn’t be this. However, the result has precedent. The first launch of SpaceX’s Falcon 1 rocket in 2006 ended in similar fashion. “Today, we know twice as much about our launch system as yesterday Continue ReadingThe first flight of Isar Aerospace’s Spectrum rocket lasted just 40 seconds

NASA’s Curiosity rover has found the longest chain carbon molecules yet on Mars

NASA’s Curiosity Mars rover has detected the largest organic (carbon-containing) molecules ever found on the red planet. The discovery is one of the most significant findings in the search for evidence of past life on Mars. This is because, on Earth at least, relatively complex, long-chain of carbon molecules are involved in biology. These molecules could actually be fragments of fatty acids, which are found in, for example, the membranes surrounding biological cells.

Femur bone density loss in mice aboard the ISS sheds light on space travel challenges

A team of biomedical engineers at the Blue Marble Space Institute of Science working with a team of bio-scientist colleagues from NASA Ames Research Center, both in the U.S., has found that test mice living aboard the International Space Station (ISS) experience a significant amount of bone loss in their femurs compared to control mice on Earth.
