Single-celled amoeba uses molecular mechanisms similar to complex life The single-celled amoeba Capsaspora owczarzaki has the same molecular tools as more complex organisms to help it move through various life stages. The findings suggest multi-celled mechanisms may have been in place long before animals evolved. Science News New questions raised about Lyme disease following discovery […]

Busy cells on the move in babies’ brains observed Neurons move through babies’ brains to where they are needed most in the first few months after birth, and these movements have now been seen by researchers. Researchers say the cells are most active in newborns, with activity slowing when the babies are about 5 months […]

Bumblebees’ emotional buzz charted Happy bumblebees are productive bumblebees, according to a study published in Science that charted how the insects’ changing moods affected their decision-making behavior. The findings are the first clues that primitive emotional states exist in bees. ScienceNews Astronomers see spiral arms surrounding new star for first time Spiral arms like those […]

Acoustic holograms can move objects with 3D sound shapes Acoustic holograms of blocks of 3D-printed plastic can create 3D sound shapes that can move objects without touching them Live Science Circadian rhythm gene linked to breast cancer spread A gene related to circadian rhythm has been linked to the spread of an aggressive form of […]

Infectious prion shaped like mattress spring Scientists have glimpsed the shape of an infectious mammalian prion, according to findings published in PLOS Pathogens. The prion, which can cause variant Creutzfeldt-Jakob disease in humans as well as mad cow disease, is shaped like a mattress spring. The Scientist Astronomers study nearby star cluster for clues about […]

Astronomers spy most distant galaxy cluster ever observed A young galaxy cluster 11.1 billion light-years from Earth is the most distant ever observed, astronomers say. Multiple space telescopes were used to spot CL J1001+0220, where nine of its 11 galaxies are furiously giving birth to stars. Space.com Dawn images, data locate ice volcano on Ceres […]

Faraway galaxy made mostly of dark matter A Milky Way-sized galaxy made up almost entirely of dark matter has been spotted 300 million light years away, and now researchers are looking for one similar to Dragonfly 44 that’s closer to the Milky Way so they might be able to finally detect the mysterious matter. “We […]

Zika could also target adult brains, study of mice suggests The Zika virus may be even more harmful than once thought, and it may attack adult brains, according to a study of mice brains. Researchers found that adult mice infected with Zika suffered significant damage to the forebrain and hippocampus, where nerve cells were killed […]

Canyons on Titan carved by rivers of methane Canyons on Saturn’s moon Titan were carved by rivers of methane in much the same way that water carved the Grand Canyon on Earth. Scientists examined radar images taken by the Cassini space probe and say that some liquid hydrocarbons may still exist in Titan’s canyons. The […]

Evidence of ancient flood uncovered in China Scientists have uncovered evidence that the myth that an enormous flood spawned China’s Xia dynasty isn’t just legend. Geologists, historians and archaeologists worked together to determine a massive flood occurred around 1,922 B.C., around the time Emperor Yu is said to have founded civilization in China.
