The domestication of corn (Zea mays ssp. mays), a global food staple with great economic and cultural importance, began in southwestern Mexico 9,000 years ago and humans dispersed this important grain to South America by at least 7,000 years ago as a partial domesticate. South America served as a secondary …

Two Australian bee species, Reepenia bituberculata and Meroglossa gemmata, have adapted their vision for night-time conditions, according to a paper published in the Journal of Hymenoptera Research; both species possess enlarged compound and simple eyes which allow more light to be gathered when compared to their daytime kin. Meroglossa gemmata. …

A new genus and species of mammaliaform that lived during the Triassic period has been identified from a partial jaw with teeth found on the eastern coast of Greenland. It represents the earliest known example of a dentary bone with double molariform roots and a crown with two rows of …

Controlled manipulation, storage, and retrieval of quantum information are essential for quantum communication and computing. Quantum memories for light, realized with cold atomic samples as the storage medium, are prominent for their high storage efficiencies and lifetime. A team of experimental physicists from the Johannes Gutenberg-Universität Mainz and Beihang University …

HL Tauri, a young star located 450 light-years away in the constellation of Taurus, is glowing at the center of an system of concentric protoplanetary rings and is producing planets, one for each gap in the ring. Worcester Polytechnic Institute mathematical physicist Dr. Mayer Humi believes HL Tauri provides an …

Minoan Linear A is still an undeciphered script mainly used on the island of Crete from 1700 to 1400 BCE. A new study published in the published in the Journal of Archaeological Science sheds light on one of the most enigmatic features of Linear A — the precise mathematical values …

  The Hubble Space Telescope has provided some amazing views of the universe. It’s easy to become complacent after seeing so many remarkable images, but Hubble can still wow us after 30 years. In a recent observation, the aging space telescope captured the expanding edge of a supernova blast wave. …

Study: Staring at Deep Red Light Can Improve Naturally Declining Vision Looking at 670-nm red light for three minutes a day can significantly improve cone color contrast sensitivity (the ability to detect colors) and rod sensitivity (the ability to see in low light), according to a new study published in …

Physicists Observe Branched Flow of Light Physicists from the Technion-Israel Institute of Technology and the University of Central Florida have experimentally observed optical branched flow in liquid soap films. Branched flow pattern shown on top of the interference color pattern generated by weak white light, making it possible to observe …

Astronomers Find Evidence of Supernova Just 600 Light-Years from Earth Astronomers have found many awe-inspiring objects in the cosmos, but a pair of astronomers 20 years ago found something just plain confusing. They spotted a straight line of ionized gas in the direction of Ursa Major, which was never really …
