Police: Man killed roommate, then shot neighbor, paramedic
DALLAS (AP) — A 36-year-old man with a criminal history killed his roommate, shot his neighbor and opened fire on responding paramedics in a Dallas neighborhood during an attack that prompted police to barricade the area for hours, investigators said Tuesday.
IS attack kills dozens at Syria camp
A jihadist assault led by suicide bombers killed dozens Tuesday at a camp for the displaced near Syria's border with Iraq, as pressure grows on the Islamic State group in both countries. The violence left at least 46 people dead and came as another surprise IS attack on Tuesday killed 10 soldiers in Iraq, to the south along the border. As the tolls mounted, US President Donald Trump and his Russian counterpart Vladimir Putin discussed the need for "safe zones" in Syria in a telephone call, said the White House.
The sound of a spacecraft passing between Saturn and its rings is straight out of 'Alien'
On April 26, NASA's Cassini spacecraft shot between Saturn and its innermost ring, going where no human-made object has gone before. Cassini has already made some new discoveries thanks to its dive through the ring plane. One of those insights is that the area between the planet and its rings "sounds" different than other parts of space surrounding Saturn.

This instrument picks up the signal from dust that vaporizes as it hits the fast-moving spacecraft. But the gap between Saturn and its rings is comparitively, and unexpectedly, silent. "The region between the rings and Saturn is 'the big empty,' apparently," Cassini project manager Earl Maize said in a statement. "Cassini will stay the course, while the scientists work on the mystery of why the dust level is much lower than expected." Scientists compared data picked up from Cassini's ring dive and a previous pass through a faint ring of dust and debris on Dec. 18, 2016. The 2016 data sounds crackly, with a high number of plasma pops heard as Cassini passed through the ring itself. The data taken by the instrument late last month, however, sounds very different. Instead of crackly pops, the April data sounds more like static from a TV screen punctuated by a high whistling noise that, according to NASA, is a type of plasma wave that scientists are planning to investigate further. "It was a bit disorienting — we weren't hearing what we expected to hear," Cassini scientist William Kurth said in the statement. "I've listened to our data from the first dive several times and I can probably count on my hands the number of dust particle impacts I hear." During that first ring dive, the bits of debris Cassini ran into were only about the size of the particles found in smoke, NASA said. Cassini is now in the last phase of its mission at Saturn. The spacecraft will continue to make dives through the gap between Saturn and its rings until the planned end of its mission in September, when it will make its death dive into the world's thick atmosphere.
