Old media can be scary – much scarier, ceteris paribus, than other objects of comparable antiquity. Film and television directors, as well as writers of fiction, who traffic in chills know that few things can insert a palpable sense of dread into a mise-en-scène more economically than a strategically placed daguerreotype (its dour or baleful inhabitants staring out from their world of sepia), a tinny voice issuing from an ancient radio, or the needle of a Victrola bobbing cracklingly in grooves of black vinyl. On the other hand, it is at least as much of a truism to say that new media, too, come freighted with anxieties as well as exhilarations: otherwise we would be less susceptible to narratives about being enslaved by a transpersonal Matrix, zombified by our cell phones, and so on. It should not surprise, then, that in our own media-saturated age a host of tropes and topoi derived from information technologies have tended to recur again and again in works of horror film and fiction. Many of these involve interactions between and among media: old technologies acting like new ones, and vice versa; categorial blurrings and hybridizations involving different media within a particular ecology, or the sense of an uncanny partnership or cooperation between them; and so on. Also common are tableaux of trans- or extra-medial transgression: e.g., the figure of dread escaping the representational field and entering the “real world” of the story. Then, too, there is the figure of prodigious or preternatural (and usually unasked-for) perceptual extension or augmentation, the trope of the technology that enables, or compels, one to see and/or hear more than is good for one.

Wide concerns have been raised that the use of cell phones could increase brain tumors. This paper systematically reviews the scientific evidence regarding the associations between cell phone use and brain tumors. The authors’ review suggests two conclusions. First, it is still controversial in regard with the significant associations between cell phone use and increased risk of brain tumors. Second, there exists extensive evidence that the amount of exposure to cell phone radiation plays a key role in determining the significant associations between cell phone use and gliomas, acoustic neuroma, and meningiomas. In general, those who use cell phones for more than ten years, using cell phones more than 20 minutes per day, or cumulative call time for more than 700 hours, or RF-EMF absorption for more than 3000 joules/kg have higher risks to develop brain tumors, whereas those who use cell phones for less than one year have lower risks.

Recently with the increase in advanced age population, the osteoporosis becomes the object of public attention in the field of orthopedics. The surface topography of the bone by scanning electron microscopy (SEM) is one of the most useful means to study the bone metabolism, that is considered to make clear the mechanism of the osteoporosis. Until today many specimen preparation methods for SEM have been reported. They are roughly classified into two; the anorganic preparation and the simple preparation. The former is suitable for observing mineralization, but has the demerit that the real surface of the bone can not be observed and, moreover, the samples prepared by this method are extremely fragile especially in the case of osteoporosis. On the other hand, the latter has the merit that the real information of the bone surface can be obtained, though it is difficult to recognize the functional situation of the bone.
