Zika Kills Cells Crucial to Brain Development; Did Volcanoes Cause Mars to Tilt?

March 7, 2016

Study: Zika Virus Infects and Kills Fetal Cerebral Cortex Cells This birth defect can cause babies to be born with an unusually small head and inhibited brain development. The scientists, who made their findings based on experiments performed with lab-grown human stem cells, discovered that the Zika virus is attracted to and infects the cells […]

Astronomers Find Massive Star Making Galaxy Cluster

September 12, 2015

Astronomers have discovered a distant and massive galaxy cluster with a gigantic and prolific galaxy at its heart that’s pumping out hundreds of stars each year. The galaxy cluster is named SpARCS 1049+56 and is located about 9.8 billion light years from Earth in the Ursa Major constellation. Galaxy clusters are areas of the universe […]

Rhythmic Light Pulses Help Astronomers Accurately Measure Medium Sized Black Hole

August 18, 2014

Astronomers have calculated that there may be about 100 million black holes in the galaxy. And they mostly fall into two sizes… stellar and supermassive.  The size difference has to do with how much mass they contain versus that of our own sun or solar mass. For some time now, astronomers have also theorized that […]
