The Milky Way’s supermassive black hole may have a dozen nomadic sibl

The Milky Way’s supermassive black hole may have a dozen nomadic sibl

At the center of the Milky Way sits a dark and dangerous beast: Sagittarius A*. Located about 26,000 light-years from Earth, our galaxy’s only known supermassive black hole is roughly 4 million times as massive as the Sun, and its immense gravitational pull can nonchalantly annihilate any object that strays too close. Fortunately for us, Sagittarius A* is like a troll under a bridge — it does not leave its post.

Genetic ancestry test users ‘cherry-pick’ which races to identify with

Genetic ancestry test users ‘cherry-pick’ which races to identify with

Genetic ancestry tests are often advertised as a tool to uncover new connections to diverse cultures and ancestries, but new research from the University of British Columbia has found people tend to pick and choose which races they identify with based on preconceived biases. Ancestry testing is part of a rapidly growing, billion-dollar industry that claims to use DNA to tell people about the parts of the world from which their ancestors originated.

Can the Kids Wait? Today’s Youngsters May Be Able to Delay Gratification Longer Than Those of the 1960’s

Can the Kids Wait? Today's Youngsters May Be Able to Delay Gratification Longer Than Those of the 1960's

Some 50 years since the original “marshmallow test” in which most preschoolers gobbled up one treat immediately rather than wait several minutes to get two, today’s youngsters may be able to delay gratification significantly longer to get that extra reward. This was the key finding of a new study published by the American Psychological Association.

India’s quest to find a trillion-dollar nuclear fuel on the south side of the moon

India’s quest to find a trillion-dollar nuclear fuel on the south side of the moon

India’s space program wants to go where no nation has gone before -– to the south side of the moon. And once it gets there, it will study the potential for mining a source of waste-free nuclear energy that could be worth trillions of dollars. The nation’s equivalent of NASA will launch a rover in October to explore virgin territory on the lunar surface and analyze crust samples for signs of water and helium-3. That isotope is limited on Earth yet so abundant on the moon that it theoretically could meet global energy demands for 250 years if harnessed.

Deepwater Horizon disaster altered building blocks of ocean life

Deepwater Horizon disaster altered building blocks of ocean life

The 2010 Deepwater Horizon oil spill disaster may have had a lasting impact upon even the smallest organisms in the Gulf of Mexico, scientists have found – amid warnings that the oceans around America are also under fresh assault as a result of environmental policies under Donald Trump. Lingering oil residues have altered the basic building blocks of life in the ocean by reducing biodiversity in sites closest to the spill, which occurred when a BP drilling rig exploded in April 2010, killing 11 workers and spewing about 4m barrels of oil into the Gulf.
