For those of you who take sandcastle building very seriously, listen up: MIT engineers now say you can trust a very simple equation to calculate the force required to push a shovel -- and any other "intruder"-- through sand. The team also found that the same concept, known as the resistive force theory, can generate useful equations for cohesive materials like muds.

Speed may not be witchcraft, but it is the basis for technologies that often seem like magic. Modern computers, for instance, are as powerful as they are because tiny switches inside them steer electric currents in fractions of a billionth of a second. The incredible data flows of the internet, on the other hand, are only possible because extremely fast electro-optic modulators can send information through fibre-optic cables in the shape of very short light pulses.

Engineers from MIT and Singapore University of Technology and Design (SUTD) are using light to print three-dimensional structures that "remember" their original shapes. Even after being stretched, twisted, and bent at extreme angles, the structures -- from small coils and multimaterial flowers, to an inch-tall replica of the Eiffel tower -- sprang back to their original forms within seconds of being heated to a certain temperature "sweet spot."

AMES, IA - The genus Nyssa L. includes several woody species with traits valued by horticulturists, but only black gum (Nyssa sylvatica Marsh.) is prevalent in the nursery trade. Considered among the most beautiful trees native to North America, cultivars of black gum provide outstanding foliage color in autumn.

CAMBRIDGE, MA -- The cost of solar power is beginning to reach price parity with cheaper fossil fuel-based electricity in many parts of the world, yet the clean energy source still accounts for just slightly more than 1 percent of the world's electricity mix.

Most people know that e-mails and facebook messages from unknown senders can contain dangerous links. However, many users still click on them - and Dr. Zinaida Benenson from the Chair of Computer Science 1 at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) has investigated why. The results of the experiment were clear: up to 56 percent of e-mail recipients and around 40 percent of facebook users clicked on a link from an unknown sender although they knew of the risks of their computer becoming infected with a virus. And the main reason? Curiosity.

Daejeon, Republic of Korea, August 29, 2016--A research team led by Professor Keon Jae Lee from the Korea Advanced Institute of Science and Technology (KAIST) and by Dr. Jae-Hyun Kim from the Korea Institute of Machinery and Materials (KIMM) has jointly developed a continuous roll-processing technology that transfers and packages flexible large-scale integrated circuits (LSI), the key element in constructing the computer's brain such as CPU, on plastics to realize flexible electronics.

Light has reciprocity with bidirectional transmission in ordinary media. Circulators and isolators are indispensable components in classical and quantum information processing in an integrated photonic circuit. Therefore, all-optical controllable non-reciprocal devices are always a hot topic in the research of photonic chips. Normal non-reciprocal devices are based on magnetic-optical material. However, incorporating low optical-loss magnetic materials into a photonic chip is technically challenging.
