Obesity is shifting cancer to young adults

A Case Western Reserve University School of Medicine researcher has compiled evidence from more than 100 publications to show how obesity increases risk of 13 different cancers in young adults. The meta-analysis describes how obesity has shifted certain cancers to younger age groups, and intensified cellular mechanisms promoting the diseases. Cancer typically associated with older adults over 50 are now reported with increasing frequency in young adults. Of the 20 most common cancers in the United States, nine are now reported in young adults. In 2016, nearly 1 in 10 new breast cancer cases, and 1 in 4 new thyroid cancer cases were in young people aged 20-44, according to the review published in Obesity. The data show that with obesity rising among younger demographics, so are cancer rates. The new review integrates animal studies, clinical trials, and public health data to help explain rising cancer rates among young adults. It describes how the childhood obesity "pandemic" promotes cancer. It also offers approaches to better track—and hopefully avert—this public health crisis.

Amazing time lapse video of evolution of the universe.
Starting with the big bang and culminating with homo sapiens, this experience unfolds time at 22 million years per second.

"By compressing all 13.8 billion years into a 10 minute scale, it shows just how young humans are, and how ancient and vast our universe is."

How are the scientific method, free market, and natural selection related?
Read +Sabine Hossenfelder's blog post to find out. I particularly like this paragraph:

In science, the most relevant restriction is that we can’t just randomly generate hypotheses because we wouldn’t be able to test and evaluate them all. This is why science heavily relies on education standards, peer review, and requires new hypotheses to tightly fit into existing knowledge. We also need guidelines for good scientific conduct, reproducibility, and a mechanism to give credits to scientists with successful ideas. Take away any of that and the system wouldn’t work.

I write to try to undo the hype in a new scientific findings where a newspaper has lathered on too much hype. I also moderate the Science on Google+ community. So I often get comments about how we should question everything, that science is about challenging everything. If you don't question everything, e.g., evolution, climate change, etc. then you aren't doing science. Sadly, these comments often come from climate change deniers, believers in pseudoscience or conspiracies.  So I often have to explain that skepticism is fine, however, when you have an extraordinary claim, you need extraordinary evidence. I've written about that before.

Skepticism doesn't equal question all things

I'm not sure many people truly understand the scientific method and IFLS doesn't help with catchy GIFs with no science or attribution.

Science is not about certainty. Science is about finding the most reliable way of thinking, at the present level of knowledge. Science is extremely reliable; it's not certain. In fact, not only it's not certain, but it's the lack of certainty that grounds it. Scientific ideas are credible not because they are sure, but because they are the ones that have survived all the possible past critiques, and they are the most credible because they were put on the table for everybody's criticism.
