A New Biology for the 21st Century

submitted by: earthandlifescience
Following the release of a National Academies report on the future of biological science, three of the study’s authors discuss its key findings. A New Biology for the 21st Century identifies how biology can help meet challenges like feeding a growing population, providing adequate health care, generating energy to meet increasing demands, and coping with global climate change. In this video, Dr Phillip Sharp, Dr. Anthony Janetos, and Dr. Keith Yamamoto explain the study’s goals and...

Pigment

submitted by: schulzbu
The video is based on an experiment of a Plant physiology course (HORT301) for Horticulture and Biology students. It is a student production geared towards middle school, highschool students and undergraduates as well as viewers who are interested in plant science. It depicts how flower pigments are analyzed using thin layer chromatography (TLC) and spectrophotometry. Investigations that shed light on the chemical and physical behavior of flower pigments are also shown as the isolated...

Pressure bomb

submitted by: schulzbu
This video is a visual 10 step instruction manual how to use a pressure bomb for measuring water pressure in the xylem of transpiring leaves. It is geared towards undergraduate students working in plant physiology labs as well as viewers who are interested in plant biology. Water in the xylem is under negative pressure. This tension can be measured by a “pressure bomb”. Tension pressure in a non-transpiring leaf is “equivalent” to water potential of cells surrounding the xylem...

PSI-Are my soybeans wearing different genes?

submitted by: schulzbu
The video PSI – Are my soybeans wearing different genes? is inspired by the popular TV show “CSI-crime scene investigations”. Here, however, the investigators are solving cases in the field of plant science investigations (PSI). The stunning phenomenon that soybean plants can survive herbicide treatments and grow on fields without weed competition is investigated using DNA extraction, Polymerase chain reaction (PCR), gene analysis etc. Transgenes are found that make the soybean plants...
