- 2101: Microwaves
- ... arc that may burn a hole in the oven. This hushed energy, electromagnetic radiation, flows all around us. All forms of matter, even your own body, produce electromagnetism -- microwaves, x-rays, untraviolet rays. It may interest you to know that whereas the human eye is sensitive to light radiation, the eye of the snake can sense infrared. Your body emits infrared radiation day and night, so snakes can see you even ...
- 2102: Current Status of Malaria Vaccinology
- ... more complex approach. He spent his time designing a vaccine against the more complex blood stage of the parasite - stopping the disease not the infection. His decision to try and create synthetic peptides raised much interest. At the time peptides were thought capable of stimulating only one part of the immune system; the antibody producing B cells whereas the prevailing wisdom required T cells as well in order to achieve protective ...
- 2103: The Great Imposters
- ... with all the features of a fat, juicy pink worm. The anglerfish lacks powerful teeth so it can't take a tight grip on its prey. Instead, it waits motionless until a small fish shows interest in the lure, and then wiggles the lure in front of the fish's mouth. When the small fish is just about to snap at the lure, the angler swallows violently, sucking the fish down ...
- 2104: Classification
- ... is a brief description of the plant. Linnaeus named it Nepeta cataria--cataria meaning, "pertaining to cats". The binomial nomenclature is not only more precise and standardized; it also relates plants together, thus adding much interest and information in the name. For instance, Solanum relates the potato, the tomato and the Nightshade. Binomial Classification Early on in naming species taxonomists realized that there would have to be a universal system of ...
- 2105: Dangers and Destructions of Floods and Hurricanes
- ... westerly direction and in the higher latitudes turn toward the northeast. In the southern hemisphere the usual path of the hurricane is initially to the southwest and subsequently to the southeast. Hurricanes travel at varying rates. In the lower latitudes the rate ranges from 8 to 32 km/hr and in the higher latitudes it may increase to as much as 80 km/hr. Those areas in which the hurricane winds ...
- 2106: Hypotheses of the Effects of Wolf Predation
- ... the complexities in multi-predator-prey systems that can involve surplus killing, additive predation between predators, enhancement and interference between predator species, switch over between prey species, and a three-fold variation in food consumption rates by wolves." Dale et al. (1994) stated that further knowledge of the factors affecting prey switching, such as density-dependent changes in vulnerability within and between prey species, and further knowledge of wolf population response ...
- 2107: Darwinism: The Theory That Shook The World
- ... for nature. When he was not reading about nature and its quirks he was out in the forest looking for wild game , fish, and insects (Campbell p 424). His father, although noting his son's interest in nature, felt that all the discoveries of the natural branch of science had been accomplished so he sent his son to medical school at Edinburgh instead (Bowler p 62). While Darwin was there, he ...
- 2108: Introduction To Evolution
- ... reptiles are thermally unstable (cold-blooded), regulating their body temperatures by behavioral activities (the phenomenon of ectothermy). Most scientists regard dinosaurs as lumbering, oversized, cold-blooded lizards, rather than large, lively, animals with fast metabolic rates; some biologists, however--notably Robert T. Bakker of The Johns Hopkins University--assert that a huge dinosaur could not possibly have warmed up every morning on a sunny rock and must have relied on internal ...
- 2109: The Application of Fractal Geometry to Ecology
- ... Palmer (1982). Palmer (1982) points out that Mandelbrot's early definition (Mandelbrot 1977) does not mention self-similarity and therefore allows objects that exhibit any sort of variation or irregularity on all spatial scales of interest to be considered fractals. According to Shenker, fractals are endless geometric processes, and not geometrical forms (1994), and are therefore useless in describing natural objects. This view is akin to saying that we can't ...
- 2110: Cryogenics: Is It Worth Waiting For
- ... better spent, which is a controversy in itself. If given a chance Mr. Young would enter his body into cryopreservation for the benefit science (Young interview). Whereas, an America On-Line--AOL--user with an interest in cryogenics feels when cryopreservation becomes a reality for an entire body, if people are willing and have the money, they should enter their bodies into cryopreservation. He thinks the shock of waking up in ...
