A major roadblock to large scale testing for coronavirus infection in the developing world is a shortage of key chemicals, or reagents, needed for the test, specifically the ones used to extract the virus’s genetic material, or RNA.
A team of scientists at the University of Vermont, working in partnership with a group at the University of Washington, has developed a method of testing for the COVID-19 virus that doesn’t make use of these chemicals but still delivers an accurate result, paving the way for inexpensive, widely available testing in both developing countries and industrialized nations like the United States, where reagent supplies are again in short supply.
The method for the test, published Oct. 2 in PLOS Biology, omits the step in the widely used reverse transcription polymerase chain reaction (RT-PCR) test where the scarce reagents are needed.
Of all the living fish in the sea, we know the whale shark to be the biggest. At up to eight or nine meters (roughly 28 feet), they eclipse all the other sharks alive in the ocean — and females reign supreme in the size stakes. But it certainly wasn’t always the case, as scientists have finally confirmed.
Published in Historical Biology, a study has confirmed that the now-extinct Otodus megalodon, or megatooth shark, once reached up to 15 meters (49 feet) in length — surpassing the present-day whale shark by almost seven meters (22 feet).
