Uncertainties added to equation for alien life New research has included uncertainties of numbers in the equation used to determine how widespread alien life might be throughout the galaxy. “We can show that, given current scientific uncertainty, we get a distribution that could make both the optimists and pessimists happy at the same time: a […]
Researchers deliver cells to mice, zebrafish using tiny robots Magnetic microrobots about the width of a hair have delivered cells to preselected sites within living mice and zebrafish. Researchers say the technology may one day be used in cell therapy and regenerative medicine. The Scientist Survey locates previously unknown galaxy cluster A previously unknown galaxy […]
Accepting asylum-seekers, migrants boosts nations’ economies An influx of migrants and asylum-seekers is beneficial to a country’s economy within five years. Researchers based their findings on 30 years’ worth of data collected from 15 Western European countries. Nature Shallow hydrothermal vents discovered near Azores Hydrothermal vents found off the Azores are not as deep or […]
Spiders spin extremely thin sheets to help them move through air Contrary to the belief that spiders “fly” with the help of just a couple of fibers, a new study shows they make triangular sheets out of ballooning fibers that are almost invisible. The sheets are largely made from silk only 200 nanometers thick. New […]
Cavers find new connections in massive Sistema Huautla Mexico’s Sistema Huautla, one of the world’s deepest cave systems, is larger than previously thought. A group of cavers and researchers found new connections while trapped by flooding inside Sistema Huautla.

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 […]
