President Obama doubled downon driverless cars this week, declaring that the federal government, not the states, should oversee the development of self-driving cars, trucks and buses. The president and Transportation Secretary Anthony Foxx said that autonomous vehicles are too valuable for public safely and technological innovation to slow down with state-by-state regulations, or lengthy rule-making processes. And besides, self-driving technology is already on the road. Witness Tesla's semi-autonomous system, autopilot, which the carmaker added to its electric-powered sedans WHEN??? The system allows the vehicle to steer itself, change lanes, adjust speed and even find a parking space and parallel park.

To the editor: I first learned to use cuss words when I joined the U.S. Army at the age of 20. It was during bayonet training when I was forcefully admonished by my drill sergeant that I wasn't being hateful enough when I thrust my bayonet into what was supposed to be the enemy. He said, "You can't kill anyone unless you hate their guts." That is when I learned to say unprintable words with venom in my voice. It took a while for me to learn how to hate.

The asset management industry is currently facing an era of rapid transformation that has the potential to change it out of all recognition. For many fund management firms, there will be a choice between embracing such change, or becoming redundant. We have already seen similar revolutions in other sectors: Amazon has completely re-written the rules of the book retailing world, Netflix has put the video store out of business, and Uber is in the process of revolutionizing the way we use taxis. For many businesses in these sectors, there was a hard choice to be made – adapt or die. Such revolutions tend not to emerge from the established companies that dominate sectors. In my father's business, airlines, the dominant players hoped to shield themselves through established practices that made it tougher for upstarts to change the way the aviation industry served its clients: the rise of the low-cost airline has forced airlines to adapt, many of them launching their own low cost carriers.

I'm sure you agree that time is the most precious commodity that none of us can afford to waste. In business, as in life, mastering time management is incredibly important. Clogged and cluttered inboxes drain valuable time and distract you from focusing on what really matters: your work. I've recently tried and tested a number of email tools and techniques in a bid to reclaim valuable time from my working day. As a result, I've genuinely been able to save an hour each day from tedious admin tasks and put that time to much better use.

If you're going to unveil a new messaging app, it had better do something unique. At this point, finding a place amongst entrenched options like Facebook Messenger, WhatsApp and iMessage is not an easy task. Google didn't quite pull it off with Hangouts when it launched in 2013. Sure, it's installed on basically every Android phone out there and anyone with a Gmail account has probably tried it, but Google's messaging strategy never quite came together in a compelling or clear way. So Google is rebooting yet again with Allo, a mobile-only messaging app that leverages the company's biggest strengths in an effort to stand out from the pack.

For California state officials, the new federal guidelines on testing and deployment of driverless cars come as a bit of a relief. Until this week, the absence of U.S. government guidance had left the state Department of Motor Vehicles -- generally in charge of registering vehicles and issuing drivers' licenses -- to take the lead role in drafting regulations to ensure the safety of self-driving vehicles. Though the federal guidelines issued Tuesday are short on specifics, the Department of Transportation will take responsibility for regulating the driving hardware and software, and it has devised a model state policy that probably will take the pressure off individual state agencies. That policy, issued jointly by the Department of Transportation and the National Highway Traffic Safety Administration, could result in changes to current California draft regulations on autonomous vehicles. "You can imagine how the California DMV would be struggling, with no technological background or engineers at their disposal, trying to figure out whether a particular autonomous vehicle is or is not safe enough to be deployed," said Robert Peterson, a law professor at Santa Clara University.

U.S. stocks inched higher Tuesday in another cautious day of trading as investors kept an eye on central banks in the U.S. and Japan. Healthcare and household goods companies led the way, while energy companies slipped. Major market indexes were higher all day but returned most of those gains at the close of trading. They rose just enough to cancel out Monday's small losses. Drug companies helped healthcare stocks make modest gains, while Exxon Mobil fell on reports that it's being investigated by securities regulators.

US consumers are getting more comfortable using mobile devices to manage their health, a new study finds. Even in the face of privacy concerns, Americans are increasingly sharing medical information, sending photos to their doctors, using fitness or activity trackers, and using AI to become active players in their healthcare. Ketchum conducted an online survey of 2,000 smartphone-owning Americans earlier this year, and found close to 58 percent of this group uses their phone to communicate with a medical professional. Almost half of respondents have a fitness, health or medication-tracking app, and 83 percent of people who use fitness or workout apps do so at least once per week. Of course, not everyone loves health apps – about a quarter of survey respondents said health and fitness tracking apps have made them feel bad, with 21 percent ending use of the apps.

Ahmad Khan Rahami, the man suspected of planting a series of bombs in New York and New Jersey over the weekend, praised Anwar Awlaki in handwritten notes found on his person after he was wounded in a shootout Monday. FBI agents recovered a notebook from Rahami after he was wounded by police in Linden, N.J., a U.S. official told the Los Angeles Times. In the notebook, Rahami describes his affinity for Awlaki, the American-born Islamic cleric who became a leader of Al Qaeda in Yemen. Awlaki was killed in a CIA drone strike in 2011, but his legacy has spread among jihadists thanks to online audio and video sermons. The notebook also contained ramblings about the Boston Marathon bombers, the official said.
