Science news in review: Nov. 18

With Thanksgiving just around the corner, this week’s review highlights scientific breakthroughs we can all be grateful for — advancements that have made a profound impact on human health in the past month. The new at-home test could correctly identify 99% negative and 92% positive COVID-19 samples. For negative Flu A and Flu B samples, 99.9% were identified correctly; for positive Flu A and Flu B samples, the test correctly identified 92.5% and 90.5% of samples, respectively. These quick and affordable tests will be a vital fix for the colder months.

Stem cells are used to drive organ growth in nonhuman animals, a key focus of human-animal chimera research. 

The pitfalls of xenotransplantation

A chimera is an organism composed of cells from two or more distinct genotypes. Human-animal chimeras are a budding area of research and involve the introduction and growth of human tissues in an animal. Chimerism research holds great promise in improving the availability of organs for organ transplantation, which is a major issue due to the current severe organ shortage. Initial chimerism studies involved smaller organisms, such as one where researchers attempted to grow a rat pancreas in a mouse.

We hope that the fall break was a good time to take a rest. Before diving back into the semester, catch up on the newest scientific discoveries! A team of researchers led by Manu Prakash at Stanford University collected water samples and observed the behavior of one phytoplankton species in particular, Pyrocystis noctiluca (P. noctiluca). Researchers learned that this species, which is most well-known for its bioluminescence, use cellular inflation to drive this migration.

Venkat argues that deepfakes have negative consequences on healthcare and public health guidance, and that action must be taken to curb their impact. 

AI misinformation has set back pandemic preparedness

In the midst of the COVID-19 pandemic, there was increased hesitancy about vaccine effectiveness. One form of misinformation is deep fakes, which are becoming more prevalent and pose serious concerns for healthcare. Deep fakes are digitally altered videos or images that can use artificial intelligence to manipulate the words of popular figures, such as politicians or health experts, and can exacerbate global health issues like epidemics and pandemics.
