  • Scientists make 3D heart using personalized bio-ink

    Over the last several years, 3D printing technology has allowed designers and enthusiasts to produce all sorts of items without an extensive manufacturing pipeline, from shoes to artwork to robots. There have been some applications in medicine, such as “printing” drugs and prosthetics, but never something as complex and critical as a human organ.

  • SpaceX and Boeing compete for funding

    It has been decades since humans last stepped foot on the moon. While unmanned landings have allowed scientists to study the lunar surface from a distance, NASA wants to do better — put humans back on the moon by 2024. Five years ago, NASA decided it would select two private providers to design and build a spacecraft that could transport U.S. astronauts to the moon. As part of its Commercial Crew ...

  • Mars may have deep groundwater

    The red planet might not be so red after all, at least on the inside. A new study from the University of Southern California Arid Climate and Water Research Center (AWARE) suggests that there could still be active deep groundwater wells on Mars, potentially resulting in surface streams in equatorial regions of the planet. The research follows a discovery by the Italian Space Agency in mid-2018 of ...

  • Sugary beverages stimulate tumors

    Sugar is in everything, from fountain drinks to pastries. While sugar might taste sweet, its effects on the human body certainly aren’t. A new study from the Baylor College of Medicine and Weill Cornell Medicine finds that high-fructose corn syrup (HFCS), a common sweetener, is directly linked to tumor growth. The study found that consuming a marginal amount of high-fructose corn syrup daily stimu...

  • Tropical tectonic collisions trigger Earth’s ice ages

    Earth goes through periodic ice ages — years or decades when global temperatures become frigid, resulting in ice sheets and glaciers covering continents far beyond the planet’s polar caps. In fact, Earth has been through three major ice ages in the last 540 million years. Scientists have long wondered what triggers these chilling times, and a joint study from the Massachusetts Institute of Technol...
