BSCS Biology . . . A Student\u27s Viewpoint

In recent years a new set of text books have appeared in high school biology courses. These have been prepared by the Biological Sciences Curriculum Study (BSCS) of the American Institute of Biological Sciences

Expansion of tele-ophthalmology for diabetic diabetic retinopathy screening during the COVID-19 pandemic

Diabetic retinopathy is the leading cause of blindness in working-age adults, ages 20-74. The tele-ophthalmology program was launch at UCD Health in 2018 and was expanded during the COVID-19 pandemic to improveearly screening for diabetic retinopathy. Assess diabetic retinopathy screening utilization during the COVID-19 pandemic. This study evaluates follow-up encounters and outcomes

A Desktop Universe for the Introductory Astronomy Laboratory

What is a well-intentioned astronomy instructor to do? There is no argument that experience with the real world is desirable in any astronomy course, especially the introductory classes that fulfill the science distribution requirements at many colleges and universities. Though it is a simple matter to take students out of doors, show them the motions of the Sun, Moon, and stars, and have them squint for a few seconds at Saturn\u27s rings through a telescope, these activities represent only a small portion of the subject matter of modern astronomy. It is simply not possible, given the constraints of time, weather, and equipment at most schools, to have students determine the photometric distance of a star cluster, measure the dispersion distance of a pulsar, or confirm Hubble\u27s redshift-distance relation for themselves.

Inhibition of Germination of Oospores of Peronospora Manshurica

Oospores of Peronospora manshurica have not previously been observed to germinate. In the present tests, however, oospores on seed coats of soybeans washed in running tap water for 1 week germinated. Each germinating oospore produced a germ tube, which developed into typical branched mycelium. Oospores were placed in the center of water-agar plates, some of which were immediately sprayed with a dilute suspension of conidia of P. manshurica. Other plates were sprayed later. Germination of conidia was inhibited in an area around the oospores. The size of the area of inhibition was proportional to the elapsed time between placing oospores on the agar and spraying the agar with conidia. A germination inhibitor has been described for the conidia of P. manshurica and the same inhibitor may be active in preventing oospore germination
