NASA’s Not Sure Where in the World This Satellite Will Crash [Space]
The 20-year-old UARS satellite has dropped out of orbit—as old satellites are wont to do—and is reentering the atmosphere. Too bad NASA can't pinpoint where—or when—exactly it will land. Could be the middle of the Pacific, could be the middle of Paris—it's a surprise! More »

First demonstration of a memristive nanodevice based on protein
Memristors - the fourth fundamental two-terminal circuit element following the resistor, the capacitor, and the inductor - have attracted intensive attention owing to their potential applications for instance in nanoelectronic memories, computer logic, or neuromorphic computer architectures. Scientists have been able to show that various materials such as metal oxides, chalcogenides, amorphous silicon, carbon, and polymer-nanoparticle composite materials exhibit memristive phenomena. One unanswered question so far has been whether natural biomaterials like proteins can be used for the fabrication of solid-state devices with transport junctions. Researchers in Singapore have now demonstrated that proteins indeed can be used to fabricate bipolar memristive nanodevices.
Famed Japanese scholar to lead NCKU Materials Science Research Center
Masahiro Yoshimura, a world-renowned expert on ceramics and materials science, has been appointed director of National Cheng Kung University's Promotion Center for Global Materials Research (PCGMR), which will be launched on September 23.
Researchers join two diamondoid structures to create the longest carbon-carbon bond
Research by a team from two European universities and SLAC National Accelerator Laboratory shows that attractive forces between other parts of a molecule can make a stretched bond joining two carbon atoms much more stable than expected. This result should lead to improvements in how scientists design new molecules, materials and catalysts.

Quantum behavior with a flash
Just as a camera flash illuminates unseen objects hidden in darkness, a sequence of laser pulses can be used to study the elusive quantum behavior of a large "macroscopic" object. This method provides a novel tool of unprecedented performance for current experiments that push the boundaries of the quantum world to larger and larger scales.

Gold nuggets for biotechnology: Introducing laser-generated nanoparticle conjugates
Bio-conjugated nanoparticles are important analytical tools with emerging biological and medical applications. Especially gold nanoparticles are of increasing interest for nanobiotechnology research and applications because of their high acceptance level in living systems and the fact that they are fairly easily conjugated with functional molecules. Ultrashort pulsed laser ablation represents a powerful tool for the generation of pure gold nanoparticles avoiding chemical precursors, reducing agents, and stabilizing ligands. The bare surface of the charged nanoparticles makes them highly available for functionalization and as a result especially interesting for biomedical applications. Starting today, such conjugates are available commercially for the first time.
