Black Hole Back Doors?; Io’s Atmosphere; No New Stars in Galaxy Center

August 5, 2016

Do Black Holes Have Back Doors? Most people describe a black hole as a cosmic object with gravity so strong that it sucks in any kind of material that comes close to it. What happens to stuff that is pulled into a black hole? Some scientists think that matter that enters a black hole gets […]

Space Snow Spotted; Frankenstein Galaxy; Fewer Allergies for Thumb Suckers

July 13, 2016

Astronomers Spot Snow Circling New Star For the first time, astronomers have been able to get a glimpse of a water “snowline” in a protoplanetary disk, which is the material surrounding a new star that may later form into planets. This water “snowline” marks the point within these left overs of star formation where the temperature […]

Antarctic Glacier Melt Could Raise Global Sea Level by Nearly 3 Meters

May 20, 2016

An international group of scientists say if climate change continues at its current rate, Antarctica’s Totten Glacier might become so unstable that it could eventually release enough water to produce an almost 3 meter rise in the global sea-level sometime in the next several hundred years. A year ago, this same group of scientists from […]

Hidden Galaxies Found, Long-Term Impact of CO2 Emissions, Meditation/Exercise Cuts Depression

February 10, 2016

Astronomers Spot Never Before Seen Galaxies behind Milky Way An international team of scientists was able to find hundreds of nearby galaxies that had been hidden by the dust and stars of the Milky Way galaxy and were able to gain new insight into a mysterious astronomical anomaly some 150 million light years away. Writing […]

Curiosity Hits Silica Jackpot; Sleep Aid & Strokes; Freshwater Supply Threatened

December 18, 2015

NASA’s Curiosity Mars Rover Finds Plenty of Silica As they reviewed data gathered by the Mars Rover, scientists found that some rocks in Gale Crater contained the chemical compound silica.  In fact they say it’s a very high amount of the compound. According to the researchers, silica is actually a combination of silicon and oxygen. […]

New Report Predicts Possible Dip in Global CO2 Emissions

December 7, 2015

An international collaboration of scientists, in a new report, predicts the percentage of global carbon dioxide emissions from fossil fuels may actually dip slightly in 2015 compared to 2014 levels. “In 2014, global CO2 emissions from burning fossil fuels grew by just 0.6 percent,” said the report’s lead author Rob Jackson, a professor of Earth […]

‘Medieval Warm Period’ May Not Have Been Global Climate Event

December 4, 2015

Some of those who argue against human causation of climate change often point to a number of Earth’s past climatic events and periods such as the ‘Medieval Warm Period’ and the ‘Little Ice Age’ as examples that climate change can be the result of natural and not necessarily anthropogenic in origin. But now a new study published in the journal ‘Science […]

Where Does Rain Go; Ocean Organics Form Cloud Ice; Hot Peppers May Fight Cancer

September 9, 2015

What Happens to Precipitation After it Falls to Earth? Have you ever wondered what happens to rain or snow once it falls on Earth? Researchers from the University of Utah and Oregon State University analyzed measurements, taken by the Tropospheric Emission Spectrometer (TES) on NASA’s Aura satellite, of the two forms of hydrogen contained within […]

New Sunspot Index Breaks Link Between Solar Activity and Climate Change

August 11, 2015

A newly updated analysis of sunspot numbers over the last 400 years suggests solar activity has nothing to do with climate change, a discovery that eliminates a key argument used by those who question human caused climate change. Some of those who suggest that climate change is not anthropogenic in nature contend that changes in the […]

T-Rex’s Teeth Structure, Lithium Found in Exploding Star, Is DC Sinking?

July 29, 2015

Structure of T-Rex’s Teeth Helped Make Them Terrifying Predators Researchers from the University of Toronto Mississauga have found evidence that one of the reasons carnivorous theropod dinosaurs, like Tyrannosaurus rex, were such successful predators was due to the unique structure of their teeth. The Canadian researchers found that T-Rex and related dinosaurs’ teeth were deeply […]
