The goal of this protocol is to manipulate the color patterns of jumping spiders and other very small arthropods with paint in order to study questions related to sexual selection, sexual cannibalism, predation, aposematism, or any other field of animal coloration.

Osteopathic Manipulative Treatment as a Useful Adjunctive Tool for Pneumonia

2014
Pneumonia is one of the top ten leading causes of death in the U.S. Osteopathic manipulative techniques (OMT) may be utilized as an adjunctive therapy in the treatment of pneumonia to enhance biomechanical and immune function; and ultimately, to reduce hospital stay, duration of antibiotics, incidence of respiratory failure, and mortality. In this video-article, we will review randomized controlled studies on the use of OMT in pneumonia patients, as well as demonstrate specific hands-on...

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Human color vision is impressive. People with normal color vision can tell apart millions of individual hues. Most amazingly, this ability is achieved with fairly simple hardware. Part of the power of human color vision comes from a clever bit of engineering in the human brain. There, color perception relies on what is known as an 'opponent system.' This means that the presence of one kind of stimulus is treated as evidence for...

Color in Coordination Complexes When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human eye.

Training Synesthetic Letter-color Associations by Reading in Color

2014
Reading in color is a new method for training letter-color associations that are typically found only in grapheme-color synesthetes. It involves an implicit form of training that has potential for long-term associative training methods because the training is a byproduct of reading and any text can be colored.
FAQs
Contrast and brightness adjustments can make boundaries and visual differences easier to inspect in photographs, maps, and remote-sensing imagery. This can clarify patterns associated with vegetation, water, soil, pollution, or land-use features. The adjustment changes how information is represented, not the environmental feature itself, so interpretation should remain connected to the original image or data.
Each property changes a different aspect of visual interpretation. Hue can alter the apparent color category, saturation changes color intensity, brightness changes lightness, and contrast changes the separation between visual values. Selecting among these properties allows environmental information to be displayed in a form that makes particular patterns easier to distinguish without treating the display adjustment as new environmental evidence.
Color may be altered through changes to the wavelengths of light recorded or displayed, or through computational adjustments to image and data values. These pathways affect how the same environmental information appears to a viewer. Recognizing that distinction helps researchers interpret color changes as processing choices and evaluate whether the resulting representation supports accurate environmental analysis.
Researchers should retain the original data or image and document the processing steps used to alter its appearance. This record makes it possible to distinguish source information from later visual adjustments and supports transparent interpretation. Such controls are especially important when modified imagery is used to communicate patterns involving vegetation, water, soil, pollution, or land use.
The method is useful when photographs, maps, or remote-sensing imagery contain environmental patterns that are difficult to see in their initial presentation. Adjustments can improve the visibility of relevant features and support clearer monitoring. Its value depends on controlled processing, because an easier-to-read image must still represent the underlying environmental information faithfully.
Enhanced representations can help separate patterns associated with vegetation, water, soil, pollution, and land-use features. The benefit applies across photographs, maps, and remote-sensing imagery, where visual organization influences how patterns are noticed and interpreted. In environmental science, this supports clearer analysis and communication while requiring researchers to preserve the source and record the adjustments applied.
