Important science and technology findings in 2018
The Gompertz-Makeham law predicts statistically the mortality rate of human beings. The key takeaway is that it is an exponential function. Every few years, the mortality rate of a human being doubles. It is not unique to human beings: most mammals and many other animals have an exponentially rising mortality rate over time. It does not affect all animals, however. Lobsters do not appear to age like we do. Many trees age in reverse, meaning that their mortality rate diminishes over time. In 2018, a scientist studying naked mole rates for decades published an analysis of over 3,000 rats and found that their mortality rate remains constant throughout their life. We do not know why naked mole rates age differently from most other mammals.
Type 1 diabetes is when your pancreas is unable to supply insulin to your cells. Though it can be treated with expensive and inconvenient insulin shots, there is no cure. In 2018, we found that a heart-disease drug can partially reverse type 1 diabetes. This could make some diabetics less dependent on insulin.
The human genome project set forth in 1990 to map the human chromosomes. We thought at the time that human beings would have 100,000 genes, but they have only about 25,000 genes. The map was completed in 2003. Yet applications of the human genome project have been scarce. In 2018, the first gene-silencing drug was approved in the USA.
