His Twitter post came only two days after Trump sent an immigration overhaul wish-list of legislative proposals to congressional leaders, including a requirement that Congress agree to a host of border security improvements and make significant changes to the green card program.

Astronaut Mark Vande Hei made fast work of greasing the big robot arm's new hand. Vande Hei and station commander Randy Bresnik replaced the latching mechanism on one end of the 58-foot robot arm last Thursday. Tuesday's work involved using a grease gun, which resembles a caulking gun, to keep the latching mechanism working smoothly. Vande Hei got a jump ahead in some greasing chores, but the two-part job still will spill into next week, in a third and final spacewalk. "Why don't we wash, rinse, repeat. Do it again in a week," Bresnik said as the 6 ½-hour spacewalk came to a close.

Japan just fulfilled a key part of its space ambitions -- and it'll have important ramifications for everything from self-driving cars to self-defense. The country has launched its fourth Michibiki satellite, which expands a "quasi-zenith" system designed to provide greater access to GPS in urban'canyons' where buildings tend to block signals from lower-orbit satellites. Needless to say, that's vital for autonomous vehicles that need GPS to get their bearings in a country dominated by sprawling cities. The military might want it, too. While Japan's armed forces are largely focused on defense, this fourth quasi-zenith satellite could help those calling on the nation to buy cruise missiles as a deterrent to North Korea.

The Supreme Court is leaving in place the conspiracy conviction of Osama bin Laden's former personal assistant by a military tribunal. The justices' order Tuesday was issued without comment and could be the final legal appeal by Guantanamo detainee Ali Hamza al-Bahlul. A military commission convicted Bahlul of conspiracy and other crimes in 2008. An appellate panel at one point ruled the military tribunal lacked the authority to convict defendants of conspiracy and other crimes that are not international war crimes. But the U.S. Court of Appeals for the District of Columbia Circuit later upheld the conviction.

Last school year, Ohio's cash-strapped education department paid Capital High $1.4 million in taxpayer dollars to teach students on the verge of dropping out. But on a Thursday in May, students' workstations in the storefront charter school run by for-profit EdisonLearning resembled place settings for a dinner party where most guests never arrived. In one room, empty chairs faced 25 blank computer monitors. Just three students sat in a science lab down the hall, and nine more in an unlit classroom, including one youth who sprawled out, head down, sleeping. Only three of the more than 170 students on Capital's rolls attended class the required five hours that day, records obtained by ProPublica show. Almost two-thirds of the school's students never showed up; others left early. Nearly a third of the roster failed to attend class all week. Some stay away even longer. ProPublica reviewed 38 days of Capital High's records from late March to late May and found six students skipped 22 or more days straight with no excused absences. Two were gone the entire 38-day period. Under state rules, Capital should have unenrolled them after 21 consecutive unexcused absences. Though the school is largely funded on a per-student basis, the no-shows didn't hurt the school's revenue stream.

WASHINGTON -- President Donald Trump suggested he's smarter than Secretary of State Rex Tillerson, saying in an interview published Tuesday that if Tillerson did call him a moron, as reported, the two should "compare IQ tests." "And I can tell you who is going to win," Trump said to Forbes magazine. An NBC News story claimed Vice President Mike Pence had to talk Tillerson out of resigning this summer, and that Tillerson had called Trump a "moron." Tillerson said he never considered resigning, though he didn't directly address the reported insult. His spokeswoman later said he never used such language.

LogRhythm today introduced CloudAI a technology designed to help LogRhythm customers across the globe avoid damaging cyber incidents such as high-profile data breaches. CloudAI is an advanced cloud-based security analytics offering that is available as a fully integrated, add-on subscription service for the LogRhythm Threat Lifecycle Management Platform. CloudAI uses artificial intelligence to detect advanced threats that employ unknown attacks and unknown methods and provide security teams immediate visibility into emerging and active user-based threats. CloudAI's machine learning-driven approach automates the detection of advanced threats through self-evolving, cloud-based analytics. This approach enables security personnel to efficiently and effectively defeat the rapidly growing volume of threats targeting their organisations daily -- even as attackers rapidly modify their methods and enterprise attack surfaces continue to expand.

Artificial Intelligence (AI) is here. It's not a future notion but is being incorporated into businesses every day. Because it has the capacity to greatly improve the efficiency of many, selected processes, thereby freeing up time for employees to use elsewhere and offering better ROI. Many people fear Artifical Intelligence as they think AI systems will overtake humanity, posing very real threats to people in addition to the common belief that they will replace employees as they invade the working environment. Over time, AI may reduce the need for certain job roles but, as the business landscape evolves, more jobs will be created.

On Sunday night, a lone gunman armed with 23 powerful weapons opened fire from a window on the 32nd floor of the Mandalay Bay casino in Las Vegas, targeting thousands concertgoers gathered for a country music festival below. Within minutes, the gunman had killed at least 58 people and injured nearly 500. There may be no more contentious issue in America than gun control, and no more emotional time to discuss it than in the days following a national tragedy like the one that unfolded in Las Vegas. But, a subject being difficult to discuss should not preclude us from trying to understand it, and fortunately nature has evolved methods for helping relatively simple organisms work through incredibly complicated problems with life or death consequences. Swarm Intelligence allows groups of bees to converge on the perfect place for their hive nearly 90% of the time, and extending this power to humans through Unanimous AI's Swarm AI technology empowers groups to create similarly optimized insight.

NASA astronauts took another spacewalk outside the International Space Station on Tuesday, this time to grease the robot arm's new hand. The pair replaced the latching mechanism on one end of the 58-foot robot arm last Thursday. Tuesday's work involved using a grease gun, which resembles a caulking gun, to keep the latching mechanism working smoothly. The two-part lube job is expected to spill into next week, in a third spacewalk. These latches, or hands, are located on each end of the Canadian-built robot arm.
