Understanding the AIDS Epidemic

In a TED Talk released this week, medical statistician Hans Rosling presents a new way to visualize the global AIDS epidemic. By displaying dollars spent per person, graphed as a function of the percentage of the population infected with HIV (by continent), we can see both how AIDS has spread, and how the money spent per patient has affected that spread. Starting in 1983, Rosling's visualization is an animated graph that dramatically demonstrates how the epidemic works, and even allows interaction -- teasing apart specific interactions in particular countries, so we can understand how different interventions have worked. Rosling is a very compelling speaker with interesting, well-presented data.

Discussed: how AIDS has spread over the past 25 years, death rates in poor countries, understanding Africa as many very different countries, infection rates by income (with surprising results), infection on a world map, and serial monogamy in Sweden (powered by vodka).

Watch a Rogue Pet Dog Interrupt a Russian News Anchor on Air

Last week, a Russian news broadcast briefly went to the dogs after its host was startled by a surprise co-anchor: a friendly black canine that wandered on set, announced its presence with a loud bark, and climbed onto her desk.

 

As TODAY reports, Mir24 TV anchor Ilona Linarte went off script for a few minutes, telling viewers "I've got a dog here. What is this dog doing in the studio?" After the initial shock wore off, she gave her furry guest a tepid welcome, patting its head as she gently pushed it off the desk. ("I actually prefer cats,'' Linarte remarked. "I'm a cat lady.")

Linarte’s query was answered when the TV station announced that the dog had accompanied another show’s guest on set, and somehow got loose. That said, rogue animals have a proud tradition of crashing live news broadcasts around the world, so we’re assuming this won’t be the last time a news anchor is upstaged by an adorable guest star (some of which have better hair than them).

SpaceX Is Sending Two Private Citizens Around the Moon

Two members of the public are set to take an historic trip around the Moon, according to an announcement from SpaceX CEO Elon Musk. As The Verge reports, the anonymous private citizens have already placed substantial deposits on the commercial space flight.

The private spacecraft company SpaceX revealed on Monday that the Falcon Heavy rocket will be launching with its Crew Dragon spacecraft in late 2018. The mission will consist of a circumnavigation of the Moon, passing over the body’s surface before traveling farther into space and returning to Earth. In total, the trip will cover 300,000 to 400,000 miles and take a week to complete.

A noteworthy part of the plan is the human cargo that will be on board. Instead of professional astronauts, the craft will carry two paying customers into space. The passengers, who’ve yet to be named, will both need to pass several fitness tests before they're permitted to make the journey. According to The Verge, Musk said the customers are “very serious” and that the cost of the trip is “comparable” to that of a crewed mission to the International Space Station. The goal for SpaceX is to eventually send one or two commercial flights into space each year, which could account for 10 to 20 percent of the company’s earnings.
