Summary
Stephen Long
Area of Science:
- Plant Science
- Agricultural Science
- Biotechnology
Background:
- Photosynthesis research traditionally focused on molecular and cellular levels.
- Understanding crop responses to environmental changes like rising CO2 and ozone is crucial for agriculture.
- Previous understanding limited C4 photosynthesis to tropical and subtropical climates.
Purpose of the Study:
- To advance photosynthesis knowledge through a multidisciplinary approach.
- To investigate crop responses to atmospheric changes.
- To engineer photosynthesis for increased crop yield and improved CO2 utilization.
Main Methods:
- Integrated molecular, cellular, organismal, and ecological research.
- Developed mathematical models and patented equipment for photosynthetic efficiency analysis.
- Utilized the world's largest open-air laboratory for crop response studies.
Main Results:
- Demonstrated that C4 plants, like Miscanthus x giganteus, can thrive in cold climates.
- Showed that maize can be adapted to cooler conditions, significantly increasing yield in the Corn Belt.
- Fundamentally changed the understanding of crop responses to rising CO2 and ozone.
Conclusions:
- Stephen Long's research shifted the paradigm for C4 photosynthesis applicability.
- His work provides new strategies for increasing agricultural productivity sustainably.
- Pioneered engineering photosynthesis for enhanced crop performance in changing environments.

02:20Milgram's Obedience to Authority
7.4K
Obedience to authority is classically demonstrated in a more famous series of social psychology experiments performed by Stanley Milgram. He was a social psychology professor at Yale who was influenced by the trial of Adolf Eichmann, a Nazi war criminal. Eichmann’s defense for the atrocities he committed was that he was “just following orders.”

A modern form of aggression is bullying. As you learn in your study of child development, socializing and playing with other children is beneficial for children’s psychological development. However, as you may have experienced as a child, not all play behavior has positive outcomes. Some children are aggressive and want to play roughly. Other children are selfish and do not want to share toys. One form of negative social interactions among children that has become a national concern is...

02:09Stereotype Threat and Self-fulfilling Prophecies
42.5K
When we hold a stereotype about a person, we have expectations that he or she will fulfill that stereotype. A self-fulfilling prophecy is an expectation held by a person that alters his or her behavior in a way that tends to make it true. When we hold stereotypes about a person, we tend to treat the person according to our expectations. This treatment can influence the person to act according to our stereotypic expectations, thus confirming our stereotypic beliefs. Research by Rosenthal and...

According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

02:13The Representativeness Heuristic
16.8K
The representative heuristic describes a biased way of thinking, in which you unintentionally stereotype someone or something. For example, you may assume that your professors spend their free time reading books and engaging in intellectual conversation, because the idea of them spending their time playing volleyball or visiting an amusement park does not fit in with your stereotypes of professors.
