Fluorescent Phytochromes
 
01:08:29
Nathan Rockwell describes research to better understand the photochemistry of plant phytochromes, which regulate plant growth in response to light — and how these unique molecules can be engineered to become switchable fluorescent proteins for use in optical imaging.

Phototropism
 
08:39
Phototropism is the growth of organisms in response to a light stimulus. It is most often observed in plants, but can also occur in other organisms such as fungi. The cells on the plant that are farthest from the light have a chemical called auxin that reacts when phototropism occurs. This causes the plant to have elongated cells on the farthest side from the light. Phototropism is one of the many plant tropisms or movements which respond to external stimuli. Growth towards a light source is called positive phototropism, while growth away from light is called negative phototropism. Most plant shoots exhibit positive phototropism, and rearrange their chloroplasts in the leaves to maximize photosynthetic energy and promote growth. Roots usually exhibit negative phototropism, although gravitropism may play a larger role in root behavior and growth. Some vine shoot tips exhibit negative phototropism, which allows them to grow towards dark, solid objects and climb them. The combination of phototropism and gravitropism allow plants to grow in the correct direction. This video is targeted to blind users.

The Warburg Effect, a poem
 
23:32
McMaster University's "Your Way" Final Project in Metabolism gave us freedom of choice to pick any topic in intermediary metabolism, any format to present our project, and a choice of group members ... We focused in on how glycolysis is altered in cancer tumors, and this is also known as the Warburg effect. Our work is in a format inspired by RSA Animate. Select peer-reviewed articles are explored in rhyme and through drawing to inspire creativity in science. Enjoy! - Jenn & Maleeha

[Journal Club] Light-inducible protein-interaction modules based on Arabidopsis thaliana
 
13:36
Light inducible control of protein-protein interactions provides powerful optical tools for manipulating biological processes. General light-mediated modules have been discovered and engineered based on Arabidopsis thaliana, expecting to be useful for controlling a broad range of cell phenomena with high temporal and high spatial resolution. In this report, I introduced two representative light-mediated protein-protein interactions systems which are suitable for mammalian cells.

PHOTOTROPISM for beginners
 
02:10
Produced with CyberLink PowerDirector. that was the program i used, and this is my dialog which I MADE!!: Well... Photo means light, and Tropism is growth in plants from an environmental stimulus. So Phototropism is A plants reaction to light, growing in a certain way and direction. Growing towards light is known as positive phototropism, and growing away from light is known as negative phototropism. Most plants usually show positive phototropism where as roots usually show the negative kind. Sometimes bind shoots use negative phototropism to climb up dark objects, such as walls, to find more light. Phototropism uses auxin's, which are plant hormones, which have lots of uses. Here they are able to react to light, and break bonds in the cell walls. Making them less rigid. And making them swell up, and creating pressure, causing growth to grow in a different direction. Phototropism is directed by light receptors, such as, cryptochromes that detect blue light, and phytochromes that detect red light. This normally takes place in the tip of the plant. A scientist once conducted a experiment on this. To do this he took three plants and cut the tips of and placed one in a normal box, and one in the same type of box but put a foil cone on its head , and finally with the last one put it again in the same kind of box but put a hole in the side. This one grew towards the hole, the one with the tin foiled hat on grew straight up and the plain one didn't grow at all. Phototropism is important for the plant as it can find more light and grow taller and taller.

CIRCADIAN rhythm - WikiVidi Documentary
 
32:49
A circadian rhythm is any biological process that displays an endogenous, entrainable oscillation of about 24 hours. These 24-hour rhythms are driven by a circadian clock, and they have been widely observed in plants, animals, fungi, and cyanobacteria. The term circadian comes from the Latin circa, meaning "around" , and diēm, meaning "day". The formal study of biological temporal rhythms, such as daily, tidal, weekly, seasonal, and annual rhythms, is called chronobiology. Processes with 24-hour oscillations are more generally called diurnal rhythms; strictly speaking, they should not be called circadian rhythms unless their endogenous nature is confirmed. Although circadian rhythms are endogenous , they are adjusted to the local environment by external cues called zeitgebers , which include light, temperature and redox cycles. In medical science, an abnormal circadian rhythm in humans is known as circadian rhythm disorder. In 2017, the Nobel Prize in Physiology or Medicine was... http://www.wikividi.com ____________________________________ Shortcuts to chapters: 00:01:33: History 00:04:09: Origin 00:08:39: Importance in animals 00:09:18: Effect of circadian disruption 00:10:06: Effect of light–dark cycle 00:11:42: Arctic animals 00:12:56: Butterfly migration 00:13:16: In plants 00:17:36: Biological clock in mammals 00:19:47: Humans 00:20:46: Biological markers and effects 00:23:46: Outside the "master clock" 00:24:48: Light and the biological clock 00:25:15: Enforced longer cycles 00:26:09: Human health 00:27:11: Indoor lighting 00:27:43: Obesity and diabetes 00:28:43: Airline pilots (and cabin crew) 00:29:24: Disruption 00:30:36: Effect of drugs ____________________________________ Copyright WikiVidi.

A circadian rhythm /sɜrˈkeɪdiən/ is any biological process that displays an endogenous, entrainable oscillation of about 24 hours. These rhythms are driven by a circadian clock, and rhythms have been widely observed in plants, animals, fungi, and cyanobacteria. The term circadian comes from the Latin circa, meaning "around" (or "approximately"), and diem or dies, meaning "day". The formal study of biological temporal rhythms, such as daily, tidal, weekly, seasonal, and annual rhythms, is called chronobiology. Although circadian rhythms are endogenous ("built-in", self-sustained), they are adjusted (entrained) to the local environment by external cues called zeitgebers, commonly the most important of which is daylight.

Plant physiology
 
22:39
Plant physiology is a subdiscipline of botany concerned with the functioning, or physiology, of plants. Closely related fields include plant morphology (structure of plants), plant ecology (interactions with the environment), phytochemistry (biochemistry of plants), cell biology, genetics, biophysics and molecular biology. Fundamental processes such as photosynthesis, respiration, plant nutrition, plant hormone functions, tropisms, nastic movements, photoperiodism, photomorphogenesis, circadian rhythms, environmental stress physiology, seed germination, dormancy and stomata function and transpiration, both parts of plant water relations, are studied by plant physiologists.

Elizabeth M. Middleton Maniac Lecture, March 28, 2018
 
50:43
Dr. Elizabeth M. Middleton, a senior terrestrial ecosystem and carbon cycle scientist at GSFC, presented a Maniac lecture entitled, "Four Satellites and a Cornfield." In this lecture, Betsy talks about her unconventional path as a woman scientist while balancing family and care-giver responsibilities. She recently claimed her 40 year NASA Certificate and Pin. During those four decades she has been fortunate to be directly involved in four satellite missions. These were Landsat (ERRSAC), EO-1 (Mission Scientist), an ESA mission (FLEX) now in formulation phase A, and a successful NASA mission concept development team (HyspIRI). In addition, she has been involved in basic research on plant physiology and reflectance characteristics. Various in situ studies include hyperspectral and BRDF properties of plant canopies, UV-B effects on soybean, and nitrogen and drought effects on photosynthesis and fluorescence in cornfields. She was also a PI and Co-PI in the FIFE and BOREAS multi-year field campaigns.
