1. If You Want to Be a Billionaire, Learn How to Code
If you want to make money in the U.S., you’d better head to Silicon Valley. Forbes just released its list of the 400 wealthiest people in America, and a surprising number made their fortunes in tech. Bill Gates topped the list for the 20th year in a row with a net worth of $72 billion and also managed to reclaim the title of world’s richest person. He’s just one of 12 members of the top 50 who made their money in the tech industry. Meanwhile, 20 billionaires under 45 cracked the top 400, more than half of whom have the internet to thank for their fortunes. Now, if you don’t mind, I’m going to go learn how to code.

2. What You Need to Know About the D.C. Navy Yard Shooting
Tragedy struck Washington, D.C. on Monday when a gunman opened fire at the Navy Yard, killing at least 12 and injuring 14 more. The shooting began shortly after 8 a.m. and shut down schools and government buildings for much of the day. After a series of standoffs, police shot and killed the suspected gunman, who was later identified as Aaron Alexis. We don’t know much about Alexis, except that he served in the Navy Reserves for four years and had an arrest record in three states. He had been working for a computer company in D.C. and entered the Navy Yard with a government-contractor access card. Police are still searching for a motive.

3. There Was a Massive Chemical Weapons Attack in Syria – and Science Proves it
We finally have scientific evidence proving a large-scale chemical weapons attack took place in Syria at the end of August. UN weapons inspectors found 85% of blood samples and 91% of urine samples from the area of the attack tested positive for sarin gas. The report didn’t point fingers, but the British and US ambassadors to the UN both said the evidence confirms Syrian President Bashar al-Assad was behind the attack. But even if the report convinces the UN to back the destruction of Assad’s chemical weapons, it won’t turn the tide in Syria’s civil war. Chemical weapons account for only 2% of Syria’s casualties.

4. This Ship Weighs Twice As Much As the Titanic, And Scientists Just Moved it
Engineers in Italy have successfully completed the first stage of the biggest maritime salvage operation ever. Crews righted the cruise ship Costa Concordia using pulleys and counterweights after working through Monday night. To put the massive undertaking in perspective, consider this: At 114,000 tons, the Concordia weighs twice as much as the Titanic. The Concordia has rested off the Italian coast, partially submerged, since it struck a reef and sank in early 2012, killing 32 passengers. It will now float in place for several months while workers assess the damage to the ship and then tow it to a nearby port.
