Cavada, Alexandre Havt, Taianá M. de Oliveira, Gustavo A. Bezerra, Valder N. Freire, Microscopy and Microanalysis, Volume 14 Issue 02 , pp 150-158 Abstract Biofilms are assemblages of microorganisms and their associated extracellular products at an interface and typically with an abiotic or biotic surface. The study of the morphology of biofilms is important because they are associated with processes of biofouling, corrosion, catalysis, pollutant transformation, dental caries, drug resistance, and so forth. In the literature, biofilms have been examined by atomic force microscopy (AFM), which has proven to be a potent tool to study different aspects of the biofilm development on solid surfaces. In this work, we used AFM to investigate topographical changes during the development process of Enterococcus faecalis biofilms, which were generated on sterile cellulose nitrate membrane (CNM) filters in brain heart infusion (BHI) broth agar blood plates after 24, 36, 72, 192, and 360 h. AFM height images showed topographical changes due to biofilm development, which were used to characterize several aspects of the bacterial surface, such as the presence of extracellular polymeric substance, and the biofilm development stage. Changes in the development stage of the biofilm were shown to correlate with changes in the surface roughness as quantified through the mean roughness. |

| • | Trends in Lung Cancer Incidence by Histological Type in Osaka, Japan |
|
In Japan, an increase in age-adjusted incidence rates of lung adenocarcinoma (ADC) and a decrease in lung squamous cell carcinoma (SQCC) have been reported. The number of lung cancer incidence, age-adjusted rates, and age-specific rates by birth-cohort according to histological type were examined using the data from Osaka Cancer Registry. The numbers of lung cancer incidence among men and women have increased, particularly in ADC. The age-adjusted incidence rates of ADC among men and women have continuously increased, while those of SQCC and small cell carcinoma (SMCC) turned to decrease since 1990s. A trough of lung cancer incidence rates was observed among men in 1935–39 birth-cohorts. The declining trend appeared in 1955–59 birth-cohorts. Lung cancer incidence rates among women have increased since 1895–99 birth-cohorts, but those rates leveled off or decreased in 1950s birth-cohorts. Trends of ADC by birth-cohort were almost the same as those of all histological types. The SQCC among men peaked in 1915–19 birth-cohorts, and decreased in the subsequent birth-cohorts. The SMCC among men peaked in 1920s birth-cohorts, and decreased or leveled off in the subsequent birth-cohorts. Lung cancer incidence rates by birth-cohorts were almost parallel to the smoking prevalence. However, those for ADC among young women in 1950s birth-cohorts were not parallel to the smoking prevalence, which requires careful monitoring to confirm such findings. |

| • | "Hairy" solar cells make better photovoltaics? |
| Materials scientists in the USA and in Germany have come up with methods of growing silicon nanowires in upright fashion on for example an indium tin oxide conductive layer. The wires, coated with either polymer or spun glass, are used as a series of channels to bring electrons more efficiently from the solar cell surface to the electrode. The technique is one of many being investigated to increase the efficiency of solar cell energy collection that holds the promise of cheap permanent power. See ecotech daily. Also, Science Daily. |

| • | Navy Engineering Camp |
With summer programs in full swing, the articles about summer science learning are starting as well. Here is one about a Navy-sponsored program, the Patriots Technology Training Center, in Maryland. This quote is specifically about recruiting Navy engineers, but it could probably apply to any program looking to engage kids in math and science: "We need to get the word-of-mouth to spread things. What we are finding is that kids are generating their own interest and it spreads very positively." The idea that science and engineering are "not cool" is mostly an adult construction that kids pick up on. Building submarines can be cool, as long as adults don't make kids sit in a classroom and get lectured about submarines. |

| • | The Role of Ultrasound in the Management of Flexor Tendon Injuries |
|
The use of ultrasound scanning to establish tendon pathologies was assessed retrospectively in 17 patients in 18 digits. The ultrasound scan demonstrated four patterns: (1) normal intact tendons in four, (2) ruptured tendons in three, (3) tendons in continuity but attenuated in five and (4) tendons in continuity but thickened with fibrosis and decreased movement representing adhesions in five patients. Surgery was undertaken in only three cases, confirming the ultrasound diagnosis in two. Surgery was offered to all three patients with ruptures but was declined by two. Ultrasound imaging helped to avoid surgery in 14 cases by excluding flexor tendon re-ruptures. This allowed on-going mobilisation, leading to recovery of function. |

| • | Scanning electron microscopic observation of the sensory region in the frog muscle spindle |
|
The equatorial sensory region of muscle spindles in the fourth toe extensor digitorum longus muscle of the adult frog was examined by scanning electron microscopy. Segments of this thin and long muscle after fixation were longitudinally cut with a razor blade and then treated with an HCl-hydrolysis method to remove connective tissues. Cells of the inner capsule extended thin and flattened cytoplasmic processes, showing a sieve-like appearance. Some specimens after a partial disruption of the inner capsule reevaluated at the fine structural level that numerous sensory terminals with varicose swellings longitudinally arranged along each intrafusal muscle fiber. |
