10 Puzzling Mysteries Solved By Science


10 Puzzling Mysteries Solved By Science
Despite centuries of study, the universe remains largely mysterious, as does the planet we call home. The unknown inspires both wonder and curiosity, which, in turn, often prompt questions. Seeking answers, we gather facts, form hypotheses, and conduct observations or experiments. Sometimes, we remain puzzled. The causes of unlikely phenomena, of seemingly impossible developments, and of strange occurrences continue to mystify us.
At other times, however, we discover, we learn, and our knowledge expands. Nevertheless, new mysteries await. There are always more puzzles to solve. Each time we manage to unravel one of the mysteries of the universe, though, we are inspired again to seek more answers. We are a species with a need to know that can’t be satisfied, even when, through science, we manage to solve puzzling mysteries like the ten on this list. ....

Our cells are filled with bones, in a sense. Thin, flexible protein strands called actin filaments help support and move around the bulk of the cells of eukaryotes, which includes all plants and animals. Always on the go, actin filaments constantly grow, shrink, bind with other things, and branch off when cells move.
Supercomputer simulations have helped solve the mystery of how actin filaments polymerize, or chain together. This fundamental research could be applied to treatments to stop cancer spread, develop self-healing materials, and more. ....

BLUES ASSOCIATION SUSPENDS FUNDING FOR LAWMAKERS WHO CHALLENGED ELECTION RESULTS: The Chicago-based Blue Cross Blue Shield Association is suspending contributions to lawmakers who challenged Joe Biden s Electoral College win, said BCBSA President and CEO Kim Keck. The associations did not name any members of Congress in a statement.
“At the Blue Cross Blue Shield Association, we continuously evaluate our political contributions to ensure that those we support share our values and goals, Keck said in a Jan. 8 statement. In light of this week’s violent, shocking assault on the United States Capitol, and the votes of some members of Congress to subvert the results of November’s election by challenging Electoral College results, BCBSA will suspend contributions to those lawmakers who voted to undermine our democracy. These contributions are made through our PAC, which is supported solely by employee contributions. ....
