Light Acquisition02:16

Light Acquisition

9.6K
In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.

Tumor Progression02:07

Tumor Progression

7.4K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Gene-Environment Interactions01:20

Gene-Environment Interactions

1.2K
Gene expression is a dynamic process that is significantly influenced by environmental factors. This interaction underlies the complex nature of biological development and the phenotypic differences observed among individuals, even among those with identical genetic makeups. Factors such as radiation, temperature, behavior, nutrition, and stress play pivotal roles in determining how genes are expressed. The concept of the reaction range is central to understanding this interaction. It posits...

Light as Energy

96.0K
The energy required to carry out photosynthesis is light— typically electromagnetic radiation from the sun. The range of all possible wavelengths is known as the electromagnetic spectrum.
Photons
A photon is a discrete electromagnetic particle or bundle of energy. Photons are characterized by their frequency, wavelength, and amplitude, similar to the properties of a wave. Waves with higher frequencies transmit more energy and have shorter wavelengths than longer wavelengths that transmit...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

4.8K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

Background and Environment Affect Phenotype02:27

Background and Environment Affect Phenotype

7.7K
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

Area of Science:

  • Ophthalmology
  • Environmental Health

Background:

  • Myopia prevalence has dramatically increased globally over the past 30 years.
  • Myopia is a leading cause of vision loss, yet its pathological mechanisms remain unclear.
  • Genetic factors alone cannot explain the rapid rise in myopia incidence.

Purpose of the Study:

  • To review the relationship between myopia and the light environment.
  • To explore the role of environmental factors, specifically light, in myopia onset and progression.
  • To discuss potential myopia control strategies related to light exposure.

Main Methods:

  • Review of basic and clinical studies on myopia and light exposure.
  • Analysis of the impact of indoor versus outdoor light environments.
  • Examination of light intensity and wavelength characteristics.

Main Results:

  • Lifestyle changes have significantly altered the light environment.
  • The light environment is a crucial factor in myopia development and progression.
  • Differences in indoor and outdoor lighting may influence myopia.

Conclusions:

  • Environmental factors, particularly the light environment, play a significant role in the myopia epidemic.
  • Modern electronic lighting may serve as a cue for myopia control.
  • Further research into light's role is essential for understanding and managing myopia.
