Two new genetic studies published this week offer some rare insights into the Indus Valley Civilization, one of the earliest human civilizations. The work helps illuminate where these people, who created one of the cradles of civilization, came from. Just as importantly, it also reveals where they went.
The Indus Valley ...read more
GC1052-DF2 is a large, but very diffuse galaxy located some 65 million light-years away. The galaxy is thought to contain a negligible amount of dark matter. This image was captured by the Advanced Camera for Surveys on the Hubble Space Telescope. (Credit: NASA/ESA/P. van Dokkum (Yale University))
Some 60 million light-years from Earth, not too far from our local galactic neighborhood, a strange little galaxy is causing a cosmic stir. This little island universe holds far fewer stars than yo ...read more
With cases of STIs on the rise, basic methods of protection are more important than ever.(Credit: Purple Anvil/Shutterstock)
When it comes to sexually transmitted infections (STIs), we all know the classics: Syphilis, chlamydia, gonorrhea and the like. But these health-class terrors are not the only microbes that can get passed on through sexual contact.
There are more than 30 known STIs, and four in particular are becoming more common at a worrying rate. Some are developing antibiotic re ...read more

Citizen scientists have repeatedly faced resistance from skeptics questioning their experience, training, and ability, but recent technological advances have brought citizen science into the digital age, transforming many aspects of the process. This ranges from the experience of being involved in a project as a citizen scientis ...read more
One-third of GE's Catalyst engine, a turboprop set to fly in the Cessna Denali, is 3D printed. It has the most 3D-printed parts of any plane engine in the world. (Credit: GE Aviation)
In 2014, eight engineers started a secret project behind the walls of GE Aviation’s headquarters. Their challenge? Build an aircraft engine with 3D printing instead of traditional manufacturing.
The engineers wanted to make an engine with fewer parts than normal – way fewer parts. The normal CT7 t ...read more
