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. -
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…" -
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. -
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... -
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. -
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. -
SOCIOLOGY and PSYCHOLOGY: How do we make a right choice? Is it up to empirical intuition or scientific deduction? No matter how elaborate science is, the theme of this world will be always full of happiness and regret, but we can just learn as much as possible to be right... -
SOCIOLOGY: The best songs rarely did poorly, and the worst rarely did well, but any other result was possible...
