Science: Race-Based Medicine, Space Tourism & Western U.S. Heatwave

Race-based medical practises are being challenged more and more, as it becomes increasingly clear they have little basis in science. 

The team finds out why adjustments for race and ethnicity are still being made in medicine, despite the potential harm and healthcare implications they cause. It’s been a massive week for the future of space tourism – the team shares a clip of a very excited Richard Branson who’s recent journey into microgravity has set the stage for the launch of Virgin Galactic’s first commercial space flights. The team gives an update on the dramatic heatwave ravaging the US, as more record high temperatures are set, continuing to leave destruction in its wake. They also explain what ‘impact gardening’ is and why it might help us find alien life on Jupiter’s moon Europa, and they share important news on the state of the cosmetics industry in Neolithic times. On the pod are Rowan Hooper, Chelsea Whyte, and Layal Liverpool.

Views: Is U.S. Healthcare System Broken? (Harvard)

Here’s a question that’s been on my mind and perhaps yours: Is the US healthcare system expensive, complicated, dysfunctional, or broken? The simple answer is yes to all.

Below are 10 of the most convincing arguments I’ve heard that our system needs a major overhaul. And that’s just the tip of the iceberg. Remember, an entire industry has evolved in the US just to help people navigate the maddeningly complex task of choosing a health insurance plan.

The cost is enormous

  • High cost, not highest quality. Despite spending far more on healthcare than other high-income nations, the US scores poorly on many key health measures, including life expectancy, preventable hospital admissions, suicide, and maternal mortality. And for all that expense, satisfaction with the current healthcare system is relatively low in the US.
  • Financial burden. High costs combined with high numbers of underinsured or uninsured means many people risk bankruptcy if they develop a serious illness. Prices vary widely, and it’s nearly impossible to compare the quality or cost of your healthcare options — or even to know how big a bill to expect. And even when you ask lots of questions ahead of time and stick with recommended doctors in your health insurance network, you may still wind up getting a surprise bill. My neighbor did after knee surgery: even though the hospital and his surgeon were in his insurance network, the anesthesiologist was not.

Access is uneven

  • Health insurance tied to employment. During World War II, healthcare was offered as a way to attract workers since employers had few other options. Few people had private insurance then, but now a layoff can jeopardize your access to healthcare.
  • Healthcare disparities. The current US healthcare system has a cruel tendency to delay or deny high-quality care to those who are most in need of it but can least afford its high cost. This contributes to avoidable healthcare disparities for people of color and other disadvantaged groups.
  • Health insurers may discourage care to hold down costs. Many health insurance companies restrict expensive medications, tests, and other services by declining coverage until forms are filled out to justify the service to the insurer. True, this can prevent unnecessary expense to the healthcare system — and to the insurance company. Yet it also discourages care deemed appropriate by your physician.

Automobiles: Decline Of The American Convertible

Rising in popularity in the 1950s and 1960s, the convertible car is an automotive American icon. It was a vehicle meant for leisure and fun. Some of the most iconic models throughout history were convertibles, such as the Chevrolet Corvette and the Ford Mustang. However, in the last few years, convertibles have been slowly declining in popularity. Along with rising prices, American car buyers, especially those with children, value practicality and functionality over looks and leisure, leading their interest towards SUV’s and midsize sedans. In 2021, convertibles make up only 0.46% of new car sales. Can the iconic design stand the test of time?

Container Shipping: How Maersk Managed Crisis

The global container business is in chaos. Surging consumer demand, covid outbreaks and a shortage of containers has led to higher volume for ocean carriers and congestion at ports.

Maersk, the world’s largest container shipper, has seen record profits. The Danish shipping firm whose customers include Walmart and Nike announced May 2021 first-quarter revenue of $12.4 billion, a 30% increase from a year earlier. Maersk has a fleet of over 700 ships and handles one in every five containers shipped by sea. The company also owns terminals around the world and has a growing land-based logistics business. On average a Maersk container ship calls on a port somewhere around the globe every six minutes.

Like its competitors the company has faced a series of obstacles in the first half of 2021 ranging from the worldwide shortage of shipping containers to the blockage of the Suez Canal. So, with vaccine rollouts in place in the U.S. and consumer discretionary spending shifting towards services will Maersk and its rivals be able to maintain their momentum? And what do bottlenecks at ports and higher freight rates mean for U.S. consumers? Watch the video to find out what’s next for Maersk.
