A study was done with mice to see if there is a biological basis behind compatibility in friends and people we choose to be in our lives. Have you ever met someone you instantly liked, or at other times, someone who you knew immediately that you did not want to be friends with, although you did not know why? This article dives into the science behind what friends you choose to hang around with. A team of researchers showed that variations of an enzyme found in a part of the brain that regulates mood and motivation seems to control which mice want to socially interact with other mice, with the genetically similar mice preferring each other.

A human gene called theCFTR gene (for cystic fibrosis transmembrane regulator) encodes aprotein that functions in the transport of chloride ions across the cellmembrane. Most people have two copies of a functional CFTR geneand do not have cystic fibrosis. However, a mutant version of the CFTRgene is found in some people. If a person has two mutant copies ofthe gene, he or she develops the disease known as cystic fibrosis. Arethe following descriptions of this disease related to genetics at themolecular, cellular, organism, or population level?A. People with cystic fibrosis have lung problems due to a buildupof thick mucus in their lungs.B. The mutant CFTR gene encodes a defective chloride transporter.C. A defect in the chloride transporter causes a salt imbalance inlung cells.D. Scientists have wondered why the mutant CFTR gene is relativelycommon. In fact, it is the most common mutant gene that causesa severe disease in persons of Northern European descent. Onepossible explanation why…
Dr Janis toboggan has two patients who were admitted to her hospital with covid-19. And she gave them both the drug known as remdesivir. Patient A got better and was released from the hospital in two days, but it took a week for patient b to recover and be sent home. That’s interesting though dr toboggan. “Why did the drug work differently in the two patients? Remedesivir seemed to help one patient but not the other. Maybe the drug speeds up recovery but the patients had different levels of infection. Or, maybe remdesvir didn’t have any effect on recovery, and the patients were just at a different places in their infections by the Novel corona virus. To find which hypothesis was a better explanation her data, Dr To boggan applies a little deductive reading. “What if I set up a situation where I have two patients at the same point in their infection and I give one the drug and one not? If remedesivir speeds up recovery, then the one with the drug will recover faster. But if…
