Hot Topics

To help you introduce newsworthy biology topics into your classroom, BioEd Online periodically produces short topical summaries and annotated slide sets on science “Hot Topics” that are receiving national attention. Each digital slide set contains slides, speaker’s notes, and keywords. Slides can be viewed in sets or accessed individually to create customized presentations, and all slides can be downloaded to, and viewed on computers or mobile devices.

To access the slides, click on a title below or choose a title from the “Hot Topics” menu to the right. (Delete the word, “Slides” from the header in the right-hand column.) If you have questions about how to use the slide sets, visit the Help/FAQ link below or contact us directly.

California Drought: Impacts and Outlook
Slide Set
California has been in extreme drought for several years, causing a statewide emergency with wide-ranging impacts. Learn how climate change is affecting California and other parts of the United States, and what it could mean in the long-term.
Polio Risk On the Rise

Adult Neurogenesis
Slide Set
The last decade of the 20th century, proclaimed the "Decade of the Brain," yielded tremendous advances in the field of neuroscience. Insights into the biology of drug addiction, as well as the neuronal mechanisms that underlie learning and memory, provided exciting revelations about some of the brain's primary functions. Perhaps the decade's most surprising finding was the discovery that the human brain is capable of generating new neurons throughout life.
Polar Vortex
Slide Set
The severe cold snap of January 2014 was caused by a polar vortex—an ominous-sounding weather phenomenon that actually is part of the normal accumulation of cold air over the poles. A polar vortex is a spinning, large area of low pressure, found over both the North and South poles.
