These photos of scientific heroes and accomplishments inspire awe and curiosity.
- Science has given humanity an incalculable boost over the recent centuries, changing our lives in ways both awe-inspiring and humbling.
- Fortunately, photography, a scientific feat in and of itself, has recorded some of the most important events, people and discoveries in science, allowing us unprecedented insight and expanding our view of the world.
- Here are some of the most important scientific photos of history:
Domestic nuclear testing wreaked havoc on thousands of families.
- Hiroshima and Nagasaki resulted in the deaths of hundreds of thousands. But new research shows that domestic U.S. nuclear tests likely killed more.
- The new research tracked an unlikely vector for radioactive transmission: dairy cows.
- The study serves as a reminder of the insidious and deadly nature of nuclear weapons.
Russia has launched several so-called "inspector satellites" that could potentially be weaponized.
- U.S. intelligence recorded a Russian rocket deploying a mysterious object during a recent mission.
- It's possibly an inspector satellite, a spacecraft designed to repair, monitor and, potentially, destroy other satellites.
- Weaponized satellites would likely be used in the early stages of a large-scale conflict, U.S. intelligence reports.
On Tuesday, Secretary of State Mike Pompeo said the U.S. will withdraw from the 1987 agreement unless Russia falls back into compliance.
- The 1987 Intermediate-Range Nuclear Forces Treaty (INF) was an agreement between the Soviet Union and the U.S. to ban mid-ranged, nuclear-tipped missiles.
- Both Russia and the U.S. have accused each other of violating the pact in recent years.
- As it stands, Russia has 60 days to return to terms agreed upon in the deal or the U.S. will withdraw from the pact.
