[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.

Photoconversion of Bilin-Binding Phytochrome: From Pr to Pfr
 
01:45
Phytochromes are bilin-containing photoreceptors that regulate various photoresponses in plants and microorganisms through photoconversion from ground state (Pr) to activated state (Pfr). In cyanobacterial phytochrome, phycocyanobilin is buried within the GAF domain of the Cp1 protein and changes conformation upon light-absorption, causing the rearrangement of the protein that initiates the cascade of photoactivated signalling (2KOI.pdb and 2KLI.pdb: ref. Ulijasz et al. Nature v463, p250).

Circadian rhythm
 
25:58
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.

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.

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.

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.

Written language only began at around 3200 BC, but spoken language has existed long ago. Learning by listening is a great way to: - increases imagination and understanding - improves your listening skills - improves your own spoken accent - learn while on the move - reduce eye strain Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone.

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" (or "approximately"), 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 ("built-in", self-sustained), they are adjusted (entrained) to the local environment by external cues called zeitgebers (from German, "time giver"), 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 awarded to Jeffrey C. Hall, Michael Rosbash and Michael W. Young "for their discoveries of molecular mechanisms controlling the circadian rhythm" in fruit flies.
