Why Do We Have an Oort Cloud?

Real Clear Science 

Ethan Siegel, Big Think

What, precisely, is in our Solar System? And how far out do we have to look before our Solar System truly comes to an end? For the first question, you might think that looking around close to the Sun is a great way to answer that question, but it's literally just the tip of the iceberg.

When Is a Scientific Experiment Beautiful?

Real Clear Science 

Milena Ivanova, Aeon Magazine

There is a long tradition among scientists of comparing scientific models, images, theories and experiments to works of art. We are told that Albert Einstein's theory of relativity, the double helix structure of DNA molecules, and images of colliding particles are beautiful, and that, just like works of art, they evoke in us aesthetic responses.

Where Is the Antimatter?

Real Clear Science 

Sabine Hossenfelder, Backreaction

Is it ant-ee-matter or ant-ai-matter? What do ants think about it and why isn't aunt pronounced aunt. These are all good questions that we'll not talk about today. Instead I want to talk about why the universe contains so little antimatter, why that's not a good question, and if there might be stars made antimatter in our galaxy.

Real Clear Science 

Audrey Nelson, Psychology Today

No one has a crystal ball when it comes to investing. However, there tend to be different styles of investing among men and women. We know that men have traditionally dominated the financial field.

The movie "Wolf of Wall Street" was itself based on the life of Jordan Belfort, the iconic masculine bro of the financial world.

Real Clear Science 

Matt Simon, Wired

Here's the thing about the stratosphere, the region between six and 31 miles up in the sky: If you really wanted to, you could turn it pink. Or green. Or what have you. If you sprayed some colorant up there, stratospheric winds would blow the material until it wrapped around the globe. After a year or two, it would fade, and the sky would go back to being blue. Neat little prank.

Mammalian Embryos Might Not Need Primitive Streaks

Real Clear Science 

Dan Robitzski, The Sc

The primitive streak—a structure that emerges in mammalian and avian embryos to help assign spatial information to cells during early development—has long been regarded as essential for the genesis of an organism's body plan and individuality, and was thus used as a landmark in ethical guidelines for stem cell research.

What Happens If You Eat Too Many Tums?

Real Clear Science 

Claire Maldarelli, Popular Science

Food is an excellent way to celebrate life's adventures. From weddings to birthdays, and backyard summer barbecues (when safe from a public health standing, of course), good cooking is at the center of so many celebrations. Still, in the presence of such abundant deliciousness, we humans tend to—on occasion—overdo it. That's where good old Tums antacids come in.



Is the WHO Inventing Diseases for China?

Real Clear Science 

Tom Chivers, UnHerd

Can you be addicted to video games? In 2018, the WHO decided to create a new entry in its big book of recognised diseases, the International Classification of Diseases, or ICD-11.
