2. Cybersecurity

So, what should Apple users do? For starters, make sure your iPhone, iPads, computers and all apps you use are kept up to date to help protect against hackers exploiting the flaws. In fact, no matter what sort of device you have, experts say you should update your software -- like, NOW -- and brace yourself for slower device speeds for a while.

3. Marijuana

The industry of green is seeing red after Attorney General Jeff Sessions rescinded a trio of memos from the Obama administration that had adopted a policy of non-interference with marijuana-friendly state laws . This means federal prosecutors can now have a serious hand in how possession and distribution is regulated in states where marijuana is legal. The news sent marijuana-related stocks tumbling and had some wondering what might happen to an industry that took in $8 billion in sales last year and is expected to grow to $23 billion nationally by 2020 and create more than 280,000 jobs.

4. North Korea

It looks like there is a bit of optimism on the Korean Peninsula. North Korea has accepted South Korea's proposal for official talks in what will be the first high-level contact between the two countries in more than two years. The person-to-person talks will be held Tuesday at the Peace House in the Demilitarized Zone between the two nations, a South Korean spokesperson said. High among the immediate priorities is North Korea's involvement in the upcoming Olympic Games in Pyeongchang, South Korea. Both nations have seemed enthusiastic about this prospect. Other nations, however, are not as enthusiastic about the apparent thaw in diplomatic relations. Leaders from Japan and the US have expressed serious concern over the escalation of North Korea's nuclear program and have cast a wary eye at this latest detente.
