Flux (biology)

In general, flux in biology relates to movement of a substance between compartments. There are several cases where the concept of flux is important.

1 Month 2 Live

One Month to Live, also called 1 Month 2 Live, was a 5-issue limited series comic book produced by Marvel Comics on a weekly basis in 2010. It was written by Rick Remender in collaboration with Stuart Moore, John Ostrander, and Rob Williams. The original concept was devised by Marvel editor Steve Wacker with the premise "What would you do with one month to change the world?" The storyline centers on a protagonist with terminal cancer, in response to Wacker's aunt having been diagnosed with cancer.

The four writers found the experience of writing the story to be especially poignant, as all had personal experiences with cancer—in particular, Remender, whose father survived a bout with cancer in 2008, and Ostrander, whose wife Kim Yale died of cancer in 1997.

Plot

In an accident with toxic waste, Dennis Sykes gains superpowers and an untreatable cancer. With a life expectancy of barely a month, Sykes launches himself on a brief career as a superhero, in an attempt to make a difference in the world while he still can, assisting the Fantastic Four in saving Ego the Living Planet from a cancerous infection and averting Hammerhead's attempt to take control of his neighbourhood. Although use of his powers made his condition worse, Sykes made a positive impression on many heroes with his dedication to doing the right thing, accepting training from Spider-Man and receiving honorary membership with the FF and the Avengers before he finally died of stress from his final battle.

Flux (metabolism)

Flux, or metabolic flux is the rate of turnover of molecules through a metabolic pathway. Flux is regulated by the enzymes involved in a pathway. Within cells, regulation of flux is vital for all metabolic pathways to regulate the pathway's activity under different conditions. Flux is therefore of great interest in metabolic network modelling, where it is analysed via flux balance analysis.

In this manner, flux is the movement of matter through metabolic networks that are connected by metabolites and cofactors, and is therefore a way of describing the activity of the metabolic network as a whole using a single characteristic.

Metabolic Flux

It is easiest to describe the flux of metabolites through a pathway by considering the reaction steps individually.The flux of the metabolites through each reaction (J) is the rate of the forward reaction (Vf), less that of the reverse reaction (Vr).

J=Vf-Vr

At equilibrium, there is no flux. Furthermore, it is observed that throughout a steady state pathway, the flux is usually determined by the rate determining step of the reaction.

Flux (song)

"Flux" is a song by English rock band Bloc Party. It was released as a single on 12 November 2007 and produced by Jacknife Lee, along with several other new songs, during the band's week in the studio after their performances at the Carling Weekend: Reading and Leeds Festivals. The song uses mostly electronic instruments and features vocalist Kele Okereke's voice manipulated through auto-tune. It was first performed live on 26 September 2007 at Covington's Madison Theater.

CD1 of the set was only released as a free CD through the 14 November 2007 issue of NME. The song peaked at number 8 in the UK Singles Chart as the band's fourth UK Top 10 single. "Flux" is featured on the re-released version of Bloc Party's second studio album A Weekend in the City and on the North American version of their third album Intimacy.

Music video

A music video for the song was directed by director Ace Norton, who has previously directed videos for The Willows, Norah Jones and Death Cab for Cutie. The video was published on NME's website on 17 October 2007. Like the Beastie Boys' music video for "Intergalactic", it pays homage to Japanese kaiju movies. It shows two giant silver robots falling in love while other monsters and robots destroy the city they are in. The band themselves do not appear in the video.

Biology

Biology is a natural science concerned with the study of life and living organisms, including their structure, function, growth, evolution, distribution, and taxonomy. Modern biology is a vast and eclectic field, composed of many branches and subdisciplines. However, despite the broad scope of biology, there are certain general and unifying concepts within it that govern all study and research, consolidating it into single, coherent fields. In general, biology recognizes the cell as the basic unit of life, genes as the basic unit of heredity, and evolution as the engine that propels the synthesis and creation of new species. It is also understood today that all organisms survive by consuming and transforming energy and by regulating their internal environment to maintain a stable and vital condition.

Subdisciplines of biology are defined by the scale at which organisms are studied, the kinds of organisms studied, and the methods used to study them: biochemistry examines the rudimentary chemistry of life; molecular biology studies the complex interactions among biological molecules; botany studies the biology of plants; cellular biology examines the basic building-block of all life, the cell; physiology examines the physical and chemical functions of tissues, organs, and organ systems of an organism; evolutionary biology examines the processes that produced the diversity of life; and ecology examines how organisms interact in their environment.

Biology (journal)

Biology is a quarterly, peer-reviewed, open access, scientific journal covering research on all aspects of biology. It was established in 2012 and is published by MDPI. The editor-in-chief is Chris O'Callaghan (University of Oxford). The journal publishes reviews, research papers, and communications.

Subject Areas

This journal covers all topics related to biology. More detail about the journal and its scope is available in the first editorial. Research fields of interest include, but are not limited to:

Biology 101

"Biology 101" is the first episode of the third season of Community. The episode originally aired on September 22, 2011 on NBC. The episode picks up where the second season left off, with Pierce out of the group. The study group resumes class at Greendale and decides to enroll in Biology.

The episode was written by Neil Goldman and Garrett Donovan and directed by Anthony Russo.

Plot

The study group decides to take a Biology class together, but Pierce soon faces problems when only six seats are available in the class. Jeff quickly makes enemies with their professor (Michael K. Williams) and is removed from the class, leaving an open slot for Pierce in both the class and their study group. Jeff's plans to reveal Pierce's relationship to the new professor backfires. Dean Pelton unwisely stokes a rivalry with Vice Dean Laybourne (John Goodman), the dean of the school's lucrative Air Conditioning Repair Annex. Abed becomes despondent when Cougar Town goes into hiatus and the group tries to cheer him up by introducing him to Cougarton Abbey, a British show that Cougar Town was based on. Unfortunately, that show was cancelled after six episodes, ending with the main characters committing mass suicide.
