Is Earth losing its atmosphere? A pair of researchers from Toho University and NASA Nexus for Exoplanet System Science has found evidence, via simulation, that Earth will lose its oxygen-rich atmosphere in approximately 1 billion years. What would happen if we lost gravity? If the Earth’s gravity did just suddenly disappear we would no longer […]
What would happen if Earth had a tilt of only 5?
What would happen if Earth had a tilt of only 5? An axial tilt of only 5 degrees, however, would mean that seasonal variations would be minimal below about 80 degrees of latitude. Without these seasonal variations, the global climate would be much more uniform, but this would also cause devastation to most of the […]
What is air pressure and what causes it?

How do you calculate ploidy?
How do you calculate ploidy? Ploidy can be assessed either by chromosome number or by flow cytometry using the DNA index (DI), the ratio of fluorescence in leukemic blasts compared to normal cells. Normal diploid cells have 46 chromosomes and a DI of 1.0, hyperdiploid cells have higher values, and hypodiploid cells lower. What does […]
