Hard to exist?
Astronomers have discovered the most massive neutron star to date, a rapidly spinning pulsar approximately 4,600 light-years from Earth. This record-breaking object is teetering on the edge of existence, approaching the theoretical maximum mass possible for a neutron star. (1) Should it be there? According to what we knew, perhaps no. But then again, we…

In a major first, scientists have detected water vapor and possibly even liquid water clouds that rain in the atmosphere of a strange exoplanet that lies in the habitable zone of its host star about 110 light-years from Earth. (1) Clouds far far away. But how can we detect clouds? How can we detect rain…

Powerful DNA-sequencing techniques have spurred an avalanche of discoveries about ancient humans, but each one comes at a price: the partial destruction of the specimens from which the DNA was taken. Anthropologists Keolu Fox and John Hawks call for researchers to think harder about safeguarding. “Unless some ground rules are established, future scientists, armed with…

Hallucinations…
Hallucinations are spooky and, fortunately, fairly rare. But, a new study suggests, the real question isn't so much why some people occasionally experience them. It's why all of us aren't hallucinating all the time. In the study, Stanford University School of Medicine neuroscientists stimulated nerve cells in the visual cortex of mice to induce an…
