Theorists predict that collisions can briefly create a beryllium nucleus in which neutrons bind two clumps of particles together the way electrons bind atoms into a molecule--in three very different configurations. Image: adapted from M. Ito/RIKEN

Researchers have revealed how a growing crack interacts with the 3-D structure of stainless steel. By using a new technique, they could determine the internal 3-D structure of the sample without destroying it. Afterwards, they initiated a crack and studied how it grew between the grains. The results could be useful to make more performing materials for, for example, safer power plants.

Plants undergo stress because of lack of water, due to the heat or the cold or to excess of light. Researchers have analyzed the substances that are triggered in plants to protect themselves, with the goal of choosing the species that is best suited to the environment during reforestation under adverse environmental conditions.

One of the easiest ways to identify an object is by its color -- perhaps it is because children's books encourage us to pair certain objects with their respective colors. Why else would so many of us automatically assume carrots are orange, grass is green and apples are red?

Engineers have made a new tiny DelFly Micro air vehicle. This successor to the DelFly I and II weighs barely 3 grams, and with its flapping wings is very similar to a dragonfly. Ultra-small, remote-controlled micro aircraft with cameras, such as this DelFly, may well be used in the future for observation flights in difficult-to-reach or dangerous areas.

At the KITP in Santa Barbara there’s a wonderful program on Gauge Theory and Langlands Duality starting up this week, with some of the talks beginning to become available. The main topic will be the relations between S-duality in quantum field theory and geometric Langlands duality that Witten and collaborators have been working [...]

Bert Schellekens has posted on the arXiv an extended 87 page argument for the anthropic string theory landscape, entitled The Emperor’s Last Clothes? While most string theorists find the existence of the landscape and the corresponding inability to get any predictions out of the theory about particle physics rather discouraging, Schellekens instead sees this [...]

From In Memoriam: William R. Bennett Jr., Laser Inventor and Collector of Data , in this past week's Yale Bulletin: Over his 38 years at Yale, Bennett carried out research in diverse fields ranging from atomic physics to computer science and acoustics... Many of the approaches Bennett used to collect data for his projects provided much amusement to his students and colleagues. For one project, he rented...
