Ageing

Ageing (British English) or aging (American English) is the process of becoming older. In the narrow sense, the term refers to biological ageing of human beings, animals and other organisms. In the broader sense, ageing can refer to single cells within an organism (cellular ageing) or to the population of a species (population ageing).

In humans, ageing represents the accumulation of changes in a human being over time, encompassing physical, psychological, and social change. Reaction time, for example, may slow with age, while knowledge of world events and wisdom may expand. Ageing is among the greatest known risk factors for most human diseases: of the roughly 150,000 people who die each day across the globe, about two thirds die from age-related causes.

The causes of ageing are unknown; current theories are assigned to the damage concept, whereby the accumulation of externally induced damage (such as DNA point mutations) may cause biological systems to fail, or to the programmed ageing concept, whereby internal processes (such as DNA telomere shortening) may cause ageing.

Aging of wine

The aging of wine is potentially able to improve the quality of wine. This distinguishes wine from most other consumable goods. While wine is perishable and capable of deteriorating, complex chemical reactions involving a wine's sugars, acids and phenolic compounds (such as tannins) can alter the aroma, color, mouthfeel and taste of the wine in a way that may be more pleasing to the taster. The ability of a wine to age is influenced by many factors including grape variety, vintage, viticultural practices, wine region and winemaking style. The condition that the wine is kept in after bottling can also influence how well a wine ages and may require significant time and financial investment. The quality of an aged wine varies significantly bottle-by-bottle, depending on the conditions under which it was stored, and the condition of the bottle and cork, and thus it is said that rather than good old vintages, there are good old bottles. There is a significant mystique around the aging of wine, as its chemistry was not understood for a long time, and old wines are often sold for extraordinary prices. However, the vast majority of wine is not aged, and even wine that is aged is rarely aged for long; it is estimated that 90% of wine is meant to be consumed within a year of production, and 99% of wine within 5 years.

Aging (journal)

Aging is a bimonthly peer-reviewed open access medical journal published by Impact Journals (Albany, New York), a publisher listed by Jeffrey Beall as a "Potential, possible, or probable" predatory open-access publisher. The journal covers research on senescence, gerentology, and the molecular mechanics of aging. It is abstracted and indexed in Index Medicus/MEDLINE/PubMed,BIOSIS Previews, and the Science Citation Index Expanded.

Team Umizoomi

Team Umizoomi is a computer animated fantasy musical series with an emphasis on preschool mathematical concepts, such as counting, sequences, shapes, patterns, measurements, and comparisons. The team consists of mini superheroes Milli and Geo, a robot named Bot, and the child who is viewing the show. Milli, Geo and Bot refer to the child viewer as their Umifriend and encourage him or her to develop their "Mighty Math Powers!" The action generally takes place in and around Umi City, a colorful city where the streets are paved with origami inspired patterns.

In the United States Team Umizoomi is shown on both Nick Jr. and Nickelodeon. It is also available on iTunes. It first aired on January 25, 2010.

On February 20, 2014, a crew member of Team Umizoomi stated that the series had not been renewed for a fifth season by Nickelodeon.

Each episode of Team Umizoomi features several or all of the following:

Internet bot

An Internet bot, also known as web robot, WWW robot or simply bot, is a software application that runs automated tasks (scripts) over the Internet. Typically, bots perform tasks that are both simple and structurally repetitive, at a much higher rate than would be possible for a human alone. The largest use of bots is in web spidering, in which an automated script fetches, analyzes and files information from web servers at many times the speed of a human.

Given the exceptional speed with which bots can perform their relatively simple routines, bots may also be implemented where a response speed faster than that of humans is required. Common examples including gaming bots, whereby a player achieves a significant advantage by implementing some repetitive routine with the use of a bot rather than manually, or auction-site robots, where last-minute bid-placing speed may determine who places the winning bid - using a bot to place counterbids affords a significant advantage over bids placed manually.
