Why isn't Pluto a planet anymore? And what is a planet anyway? Astrophysicist Jackie Faherty explains!
Susanne Rafelski, Director of ASsay Development at the Allen Institute for Cell Science, answers the question on this edition of "Ask a Scientist."
With a little help from the National Science Foundation, spiders have presented exciting ways to improve people's lives, safety and even food supply
National Science Foundation-funded researchers at Duke University have discovered how uniquely shaped artificial material or metamaterial can control the transmission, redirection and reflection of sound waves with almost perfect efficiency
A new prosthetic ankle, developed by a team at Vanderbilt University, has a tiny motor, actuator, sensors and chip that work together to either conform to the surface that the foot is contacting or remain stationary, depending on what the user needs
What are the challenges of working in synthetic biology? Drew Endy, associate professor of bioengineering at Stanford University, answers the question on this edition of "Ask a Scientist"
Researchers are developing new methods for sequencing entire strands of DNA from humans or bacteria in just 100 seconds, which could lead to transformative advances in biology and medicine
Researchers at Texas A&M University and Stevens Institute of Technology are laying groundwork to develop the next generation of biomedical materials used to treat chronic wounds
Researchers at Washington University in St. Louis took the classical Maxwell's Demon experiment to smaller scales as they worked out a quantum theory of thermodynamics
Genes turn on, fluids go surfing, radioactivity spills from a cosmic collision and an oceanic plate crashes the party at Earth's mantle
Electric vehicles may one day be able to recharge while driving down the highway, drawing wireless power directly from plates installed in the road that would make it possible to drive hundreds -- if not thousands -- of miles without having to plug in
Less than half of the rain that falls from a cloud makes it all the way to the ground because a lot evaporates while falling or after landing in treetops
A new target for antibiotics, a dodecahedron device for the deep sea, electronic stickers to scale up the Internet of Things and self-fertilizing bacteria with rhythm
What does a sustainable energy future look like? Jack Brouwer of University of California, Irvine, answers the question on this edition of "Ask a Scientist"
With support from the National Science Foundation's Directorate for Social, Behavioral and Economic Sciences, psychologist Brad Duchaine and his team are studying the brains of 20 people with acquired prosopagnosia to better understand the computational and neural basis of face processing
Engineers at Purdue University and the University of Virginia have developed a new fabrication method that makes tiny, thin-film electronic circuits peelable from a surface
Using sound waves, researchers have developed a gentle, contact-free method for separating circulating tumor cells (CTCs) from blood samples that is fast and efficient enough for clinical use
The Center for Autonomous Systems and Technologies (CAST) is an interdisciplinary research center focused on developing autonomous systems that think, act and assist independently, expanding the scope of human possibility to solve problems, as well as the range of exploration in extreme Earth and space environments
Are pterodactyls and other pterosaurs considered dinosaurs?
