He passed away this morning.

The liver has a key role in drug metabolism, thus the liver toxicity as well as the models of human liver will still be the intense focus. Recently, there is a more accurate liver model with improved testing for a wide range of chemical compounds, reported Nature Biotechnology. It's hopeful for drug development because our livers have been overloaded much.

Do as want is ultimate judgment for any designed device. So please note to use Zhonglin's nanogenerator as a nano-charger or trigger for therapeutic nanomachine. It's a splendid direction really deserved your attention.

Laboratory fellows are the enemy of theory. Although so many times they work vainly, they indeed believe that everything is possible, if you do. For example, last year, we got the first fingerprint of p-type InN.

Graphene, a single layer of carbon atoms that pack into a honeycomb lattice, can stand up with frozen strain waves.

Do these findings suggest that we should start a new chapter on full polymer-based electronics with polyaniline nanotubes and films, which is just similar to what we have done well for inorganic carbon nanotube? It may be in time.

CELL BIOLOGY; PSYCHOLOGY: The U. S. FDA sent a new year's gift to the industries that producing the human foods derived from clones' offspring. The agency believes the safety of animal clones, and therefore strongly intends to issue passport for these foods without source labels. LivelyUpdatedNews: V20070102...0123

The incorporation of Laponite nocrystallites into polyurethane can greatly impact the elastic modulus of the polymer. Beyond the underlying refinement and its contribution to material science, this research really pulls us back to think for a while something simple.

PHYSICS: It is found out that strong oscillations exposed on the laser-excited photoluminescence spectrum of porous alumina film show highly sensitive to the film's thickness and the refractive index. The oscillating period is corresponding to the difference between two longitudinal modes within a Fabry-Pérot optical cavity. The method, designated as Photoluminescence Oscillations, endows photoluminescence spectrum with a fascinating dimension.

BIOMATERIALS: Now maybe we can set a bone once broken and stanch blood as soon as possible. Days ago, Galen D. Stucky's group reported in Small that the modified bioactive glasses showed faster biological response to simulated body fluids, thus could have a great potential for in vivo bone-forming bioactivity and accelerated blood-clotting.

ASTRONOMY: We have the first image of a flared disk with a young star HD 97048 who is 2.5 times the mass of Sun. Researchers from France and the Netherlands deduced that the debris disc, 12 times larger than our solar system, should be a stellar nursery with possible planet babies only about 3 days old if we regard our 4.6-billion-years-old Sun as only 40 years old.

SOCIOLOGY; BIOLOGY: On 19 October 2006, IBM lost a war with epidemiologist Richard Clapp of Boston University who used the health files of IBM employees' to evaluate the potentially excess cancer risk in semiconductor clean room.

Recent stones recommended by Scidea Sketch...CELL BIOLOGY: Of 90% of 13,023 CCDS genes evaluated successfully, 1149 were mutated, 236 were validated, and 189 were cancer genes (CAN genes). Individual breast cancers examined in the discovery screen harbored an average of 12 mutant CAN genes, whereas in colorectal cancers was 9. Notably, each cancer specimen of a given tumor type carried its own distinct CAN-gene mutational signature, as no cancer had more than six mutant CAN genes in common with any other cancer. Aside from its importance in the description of two common tumor types, breast and colorectal cancers, this groundbreaking study surely extends our understanding of underlying evolution of human tumors due to complex pathways of genes' mutations. Beyond science, it's love for every lady and her family.

"We captured from across the depths of space our own planet, a pale blue orb, seen amidst the pageantry and colorful splendor of Saturn's rings. Nothing has greater power to alter our perception of ourselves and our place in the cosmos than the sight of Earth from faraway places…"

PHYSICS, MATERIALS: The large-scale MD simulation fully sketched a time-resolved relaxing picture of copper single crystals during the initial phase of shock compression beyond the elastic limit. Despite providing a measure of 3D hydrostatic relaxation constant, the product of the mobile dislocation density and average dislocation velocity that is important for understanding the dislocation dynamics upon strong deformation, the study really reveals an underlying physics: how small can be a dislocation for certain material?

Just how mathematical is nature? Is it a dance with pi, e and alpha?... The question of how to calculate the numerical value of the fine structure constant from theory was one of the most outstandingly difficult problems in mathematical physics for the greater part of the 20th century.

PHYSICS, MATERIALS: The findings of mesostructural material with high-than-expected strength suggest strong guarders during fatally shocking. The typical samples are the multilayer CNTs' arrays, colloids particle film and porous metals, for example, nanoporous Au. However, considering the present progresses in nanoscience, it is too early to claim a mechanical phase map for meso/nano-porous materials, because we have not known clearly about the dislocation mechanics of nanowires…

CELL BIOLOGY: Take a deep breath and hold it longer; pinch your nose shut…you will have to choose a way to hold yourself underwater or escape from a heavy smoke. Surprisingly, model plant of Arabidopsis also can do like people...

BIOLOGY: By overexpressing of the stress responsive gene SNAC1 of model plant of Asian rice (Oryza Sativa L.), China researchers now can encode the rice with powerful potential in regulating stomatal movement. This transgenic rice was more sensitive to abscisic acid and lost water more slowly by closing more stomata, yet showed no significant difference in the rate of photosynthesis, thus no yield penalty. Importantly, it was resistant to severe drought and salinity under practical field test...

BIOLOGY: Trap-jaw ants (Odontomachus bauri) can use their hard jaws to strike ground or other substrate, or the intruder with remarkable speeds and accelerations. This superstrike is powerful enough to knock away, stun or/and kill their enemy, or in a life crisis of meeting with terrible tongue of a lizard, result in strong ballistic propulsion to rapidly bounce themselves far away...

CELL BIOLOGY: Besides the unfolded protein etc., the dysfunctional mitochondria due to the enzyme PARL losing and the membrane cristae remodeling gives a good understanding of the cell's aging and the Parkinson's disease...

PHYSICS: a mercury clock hits the timekeeping record and is expected to drift by only 1 second in 400 million years compared with 1 in 60 million in the caesium clock of NIST-F1 in 2005. Whether or not the CGPM will redefine the second, this measurement is too precise beyond endurance.

NEUROSCIENCE: During the second half of the first year, baby comes to predict others' actions.

We have paid much attention to make single crystal nanowires, now it is time for nanocrystals with defects, that is, how we can introduce controlled defects such as twinning, stacking faults, and dislocations in nanocrystals?

The simplest is the most difficult and beautiful.

The strong piezoelectricity of ZnO nanowires array has been confirmed. It gives a paradigmatic nanogenerator to convert mechanical energy into electricity with a transfer efficiency of 17 to 30%. The method has a great potential for powering nanodevices, and enables implanted biodevices with self-powered ability, enhanced performance, durability and biosafety.

Dislocations in single crystalline, undoped strontium titanate may be used as small memory-bits. The bistable switching of the conductance between non-metallic and metallic behaviour provides an alternative access to possibly non-volatile memory for high-storage density applications at room temperature.

Notes: It's p-InN.

Now semiconductor indium nitride (InN) can conduct positive charges. For any other semiconductor the news would be unremarkable. But InN is one of the most frustrating, if most promising, of semiconductor materials.
