4-D printing is unfolding as technology that takes 3-D printing to an entirely new level

Engineering researchers at the University of Arkansas have invented a novel electrical power converter system that simultaneously accepts power from a variety of energy sources and converts it for use in the electrical grid system.

With some ingenuity and interdisciplinary help, Nick Kaplinsky’s pipe dream became a reality.

Scientists recreate natural insect repellent.

An international team of researchers has sequenced the nearly complete genome of two Siberian woolly mammoths—revealing the most complete picture to date—including new information about the species’ evolutionary history and the conditions that led to its mass extinction at the end of the Ice Age.

Salk scientists use molecular "scissors" to eliminate mitochondrial mutations in eggs and embryos.

A key protein associated with autism, addiction and depression influences brain connections

Thermal imaging, microscopy and ultra-trace sensing could take a quantum leap with a technique developed by researchers at the Department of Energy’s Oak Ridge National Laboratory.

For centuries, humans have sought to learn whether life exists beyond Earth. That answer is closer than ever to fulfillment, and an Arizona State University team is working on a key part of that quest with NASA’s backing.

Light can come in many frequencies, only a small fraction of which can be seen by humans. Between the invisible low-frequency radio waves used by cell phones and the high frequencies associated with infrared light lies a fairly wide swath of the electromagnetic spectrum occupied by what are called terahertz, or sometimes submillimeter, waves. Exploitation of these waves could lead to many new applications in fields ranging from medical imaging to astronomy, but terahertz waves have proven tricky to produce and study in the laboratory. Now, Caltech chemists have created a device that generates and detects terahertz waves over a wide spectral range with extreme precision, allowing it to be used as an unparalleled tool for measuring terahertz waves.

While a May 20 ruling by a Manhattan Supreme Court Justice appeared to grant legal personhood to two research chimpanzees from Stony Brook University, the Nonhuman Rights Project later clarified that the judge will hear arguments on whether or not the chimps will remain at the university and whether or not they could be considered "persons" in the eyes of the law, but has not  yet made a final decision granting them legal personhood.
