Companion star’s temperature differences help weigh massive pulsar The close proximity of its companion star has helped researchers weigh a huge pulsar in the binary system PSR J2215+5135. Astronomers measured the temperature differences and the Doppler shift on the two sides of the pulsar’s companion star to discover that the pulsar weighs more than twice […]
A billion comets may have played role in Pluto’s formation A vast number of comets may have been involved in the formation of Pluto, according to researchers studying the dwarf planet’s Sputnik Planitia glacier plus data from New Horizons and the spacecraft that studied Comet 67P/Churyumov-Gerasimenko. “We found an intriguing consistency between the estimated amount […]
Crops could get nutrient boost from nanoparticles Nanoparticles typically used to treat cancer in humans could be used to deliver nutrients to malnourished plants. Crops are better able to absorb fertilizing nutrients delivered by liposomes than from traditional nutrient spray. Science News Tiny robot uses laser power to fly A tiny flying robot called RoboFly […]
Astronomers chart 3D map of gas cloud, revealing its flat shape The shape of a gas cloud in the Musca constellation has been mapped in 3D, giving astronomers an idea about why it has failed to produce stars. The 3D map shows the cloud is a thin, flat square, with the gas spread out more […]
Climate change disrupting lives of Europe’s bats The changing climate in Europe is affecting bats, disrupting their hibernation and hurting their ability to feed their offspring, which are being born sooner, according to researchers. BBC Studies describe “global road map of development” Using single-cell sequencing, researchers have mapped out the growth of individual cells in […]
ESA’s Gaia mission releases 2nd data set on Milky Way observations Scientists are studying the latest data from the Gaia satellite, launched by the European Space Agency in 2013 to chart the Milky Way’s stars with great accuracy, in search of new discoveries about the galaxy. This is the second set of data received from […]
New species of exploding ant discovered in Borneo A new species of exploding ant has been found in Borneo. Female worker ants in the Colobopsis explodens species sacrifice themselves to protect their colonies from threats by rupturing a part of their abdomens and releasing a toxic substance that covers their adversaries . Live Science New […]
Researchers devise method to join two single, specific atoms into new molecule Chemists used laser tweezers to grab a sodium atom and a cesium atom to create a new molecule in a highly controlled chemical reaction. Science News How cancer might progress by studying cells’ evolution Researchers charting the genetic evolution of seemingly similar cancer […]
Drones and satellites to find ancient geoglyphs in Peru More than 50 new geoglyphs have been found in the Peruvian desert by archaeologists using drones and satellites. Some of the geoglyphs appear to be Nasca lines, while others could have been etched by the Paracas and Topara cultures, which existed earlier, between 500 B.C. and […]
Earth-sized metal-heavy exoplanet found An exoplanet about the size of Earth, but metal-heavy like Mercury has been discovered about 339 light-years away. Scientists think K2-229 b’s similarities to Mercury could help explain why Mercury’s composition is so different from other planets in our solar system.
