The Scientific Method01:32

The Scientific Method

220.2K
The scientific method is a detailed, empirical problem-solving process used by biologists and other scientists. This iterative approach involves formulating a question based on observation, developing a testable potential explanation for the observation (called a hypothesis), making and testing predictions based on the hypothesis, and using the findings to create new hypotheses and predictions.
Generally, predictions are tested using carefully-designed experiments. Based on the outcome of these...

Limits to Natural Selection01:38

Limits to Natural Selection

30.0K
Organisms that are well-adapted to their environment are more likely to survive and reproduce. However, natural selection does not lead to perfectly adapted organisms. Several factors constrain natural selection.

Threats to Biodiversity01:50

Threats to Biodiversity

21.7K
There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...

Global Climate Change01:50

Global Climate Change

24.4K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Free Energy01:21

Free Energy

42.3K
Free energy—abbreviated as G for the scientist Gibbs who discovered it—is a measurement of useful energy that can be extracted from a reaction to do work. It is the energy in a chemical reaction that is available after entropy is accounted for. Reactions that take in energy are considered endergonic and reactions that release energy are exergonic. Plants carry out endergonic reactions by taking in sunlight and carbon dioxide to produce glucose and oxygen. Animals, in turn, break...

Conditions on Early Earth02:06

Conditions on Early Earth

67.0K
Around 4 billion years ago, oceans began to condense on earth while volcanic eruptions released nitrogen, carbon dioxide, methane, ammonia, and hydrogen into the primordial atmosphere. However, organisms with the characteristics of life were not initially present on earth. Scientists have used experimentation to determine how organisms evolved that could grow, reproduce, and maintain an internal environment.

    Summary

    Rising costs in Venezuela challenge scientific journal printing. Investigaci6n Clinica must balance print and digital formats to maintain accessibility and international standards despite technological and political hurdles.

    Area of Science:

    • Scientific publishing
    • Journalism
    • Venezuela

    Background:

    • Rising costs of printing materials in Venezuela
    • Challenges in obtaining imported paper
    • Difficulties in document handling

    Discussion:

    • Investigaci6n Clinica faces pressure to transition to digital format
    • Barriers to digital transition include limited institutional access and university technological limitations
    • Political instability in Venezuela poses risks to digital technology adoption

    Key Insights:

    • Continued print publication is necessary due to national distribution and international exchange commitments
    • Maintaining print quality is crucial for author and reader engagement
    • Inclusion in new international indices (SEIIC, Infobase Index) necessitates sustained excellence
