Since the shooting at Marjory Stoneman Douglas High School in February, a divisive idea has gained momentum as a way to stem school shootings: arm teachers. At some schools in Ohio, armed teachers have been in classrooms for as many as five years.
Israeli warplanes on Monday conducted strikes against nine Hamas "military targets" in the northern Gaza Strip in response to incendiary kites being sent into Israeli territory, the army said. The attacks targeted two Hamas military sites and a munitions manufacturing site, the military said in a statement, without specifying whether the raids had resulted in casualties. "Fire balloons" and kites carrying flammable material have become symbols of the Palestinian border protests in recent months.
Could a volcanic eruption be the key to unlocking the mysterious geological history of Mars? Back in the 1960s, NASA's Mariner spacecraft discovered an extremely large and unusually soft rock formation. The makeup of the mass, now known as the Medusa Fossae formation, stumped researchers for decades because they were never able to determine how it got there. SEE ALSO: Tiny NASA satellite bound for Mars snaps photo of Earth from thousands of miles away But now, new research seems to answer that question — and maybe many others. More than 3 billion years ago, extreme volcanic eruptions on Mars dropped the huge deposit near the Martian equator, according to the new study published in the

Ojha and his colleagues used gravity data from spacecraft orbiting Mars to measure the formation density. Through this, they were able to determine that the rock was unusually porous, allowing them to rule out other potential compositions like ice. On a basic level, the formation is a bunch of hills and mounds of sedimentary rock but because much of Mars’s history is shrouded in mystery, a finding like this is huge.

A considerable amount of “climate-altering” gases like hydrogen sulfide and sulfur dioxide accompany most volcanic eruptions and would have spit out enough water to cover the red planet in a global ocean, the study says. These findings paint a better picture of what habitability on Mars would look like, as well as the usefulness of gravity surveys. “Future gravity surveys could help distinguish between ice, sediments and igneous rocks in the upper crust of the planet,” co-author and planetary scientist Kevin Lewis explained.

It was not, perhaps, the most somber moment in the history of the U.S. Senate. In the midst of reciting a list of complaints about FBI agents allegedly swayed by their own anti-Trump animus, Sen. John Kennedy R-La., had to engage in a subtle act of censorship.
