The measles virus has been around for thousands of years, and is one of the most contagious diseases known to man. Its outbreaks have been responsible for the deaths of millions of people. Take a deep-dive into the disease and the science behind it with Seeker's SICK Opinion: Are booster shots needed for measles? Don't stop where the ink does.

As fascinating as it is mysterious, dark matter is one of the greatest enigmas of astrophysics and cosmology. It is thought to account for 90 percent of the matter in the universe, but its existence has been demonstrated only indirectly, and has recently been called into question. New research conducted by SISSA removes the recent doubts on the presence of dark matter within galaxies, disproving the empirical relations in support of alternative theories. The study, published in the Astrophysical Journal, also offers new insights into understanding the nature of dark matter and its relationship with ordinary matter. Read more at Phys.org

By CARLY CASSELLA (NoSystem images/iStock) Chronic fatigue syndrome (CFS), also known as myalgic encephalomyalitis (ME), is a debilitating and misunderstood disease, more accurately defined by what it isn't than what it is. With no known cause, few unique symptoms and little else for doctors to go by, reliable and consistent diagnosis is difficult to achieve. A simple blood test could change all of that, and researchers at Stanford think they might have stumbled upon just the right test. In a pilot study of 40 people, the team was able to pick out each and every one of the 20 participants with CFS, based solely on how their immune cells responded to stress.

The main purpose of an engineering journal is to prove you have done the work. Not only does this to support claims of patent, it improves your learning. You learn a lot more from your mistakes. Nobody goes directly from point A to B. It is the bad ideas that prove a journal is real. Any journal that contains only the good stuff is useless. Don't stop where the ink does.

By Jillian C. York and Corynne McSherry Social media platforms regularly engage in “content moderation”—the depublication, downranking, and sometimes outright censorship of information and/or user accounts from social media and other digital platforms, usually based on an alleged violation of a platform’s “community standards” policy. In recent years, this practice has become a matter of intense public interest. Not coincidentally, thanks to growing pressure from governments and some segments of the public to restrict various types of speech, it has also become more pervasive and aggressive, as companies struggle to self-regulate in the hope of avoiding legal mandates.

By Susan Lloyd Swail, Senior Manager, Livable Communities The last time people were priced out of the housing market was in the early 90’s. Back then, the options were limited to owning a home or renting an apartment, with some condos thrown in. Ontario’s Growth Plan for the Greater Golden Horseshoe has greatly increased the mix of housing supply, but didn’t solve affordability for people as a limited supply of rental and low-income housing was been built. The majority of new rental units being built are luxury units and many of the houses are over 2000 sq ft and are consequently unaffordable. What most people need, whether they buy or rent, are affordable places, such as townhomes, laneway housing, shared housing and non-luxury apartments.

By Anand Ram · CBC Japan, France have learned how enshrining protections in law can have unintended consequences A man holds a copy of the 'Labour Code - Code du Travail' while taking part in a nationwide day of protest against labour reforms in Bordeaux, France, on March 9, 2016. The next year, France enshrined the 'right to disconnect' into law, so that employees don't have to deal with work emails during off hours. (Nicolas Tucat/AFP/Getty Images) Leaving aside the personal and human toll, stressed-out workers cost countries a lot of time and money. The U.K.'s Health and Safety Executive said more than 11 million days were lost to work-stress, anxiety and depression in 2015-2016. In 2012, the German labour minister said stress leave and early retirement from worker burnout was costing the country up to $10 billion a year. But even when governments act, it's not clear policy alone can solve the problem. Read more at CBC News

Getting a photo of a polar bear might seem harmless, but it can be anything but Carrie Barry Dyson snapped this picture from safe inside her cabin in Batteau, Labrador. She says the bear gave her quite a scare. (Submitted by Carrie Barry Dyson) A picture of a nearby polar bear is impressive, but it can also be dangerous to get. That's why wildlife enforcement officers are discouraging the public from stopping for a snap if they see one of the big white bears in the wild. There have been multiple polar bear sightings across Newfoundland and Labrador, from Carmanville to Cartwright, already this spring. It can be tempting to prove you've seen one of the bears in person, but Colin Carroll with the province's Department of Land Resources said a photo isn't worth the risk. Read more at CBC News

Relive the final scene from "The Dragon and the Wolf."

Today's Pope Fights covers the history and aftermath of the Protestant Reformation and Catholic Counter-Reformation.

By Liz Fuller-Wright, Princeton University Neither the continents nor the oceans have always looked the way they do now. These “paleomaps” show how the continents and oceans appeared before (top) and during (bottom) “the collision that changed the world,” when the landmass that is now the Indian subcontinent rammed northward into Asia, closing the Tethys Sea and building the Himalayas. Global ocean levels were higher then, creating salty shallow seas (pale blue) that covered much of North Africa and parts of each of the continents. A team of Princeton researchers, using samples gathered at the three starred locations, created an unprecedented record of ocean nitrogen and oxygen levels from 70 million years ago through 30 million years ago that shows a major shift in ocean chemistry after the India-Asia collision. Another shift came 35 million years ago, when Antarctica began accumulating ice and global sea levels fell. Credit: Images created by Emma Kast, Princeton University, us...

By Max Planck Society The amacrine cell CT1 from the Drosophila brain works with its subunits like 1400 individual cells Credit: © MPI of Neurobiology / Meier CT1 is different. In general, a nerve cell receives input from a number of presynaptic cells, processes the signals, and passes its output to downstream cells. In the cell CT1, however, each of the approximately 1400 cell areas works like a separate neuron. This allows CT1 to access information from all facets of the fly's complex eye and to contribute locally to the calculation of motion direction. Using a computer model of the cell, Alexander Borst and Matthias Meier from the Max Planck Institute of Neurobiology show that CT1 is reaching biophysical limits. Read more at Medical Xpress

By Jesse Firempong UPDATE: The City of Toronto’s Environment and Infrastructure Committee passed the motion on pursuing compensation for the cost of climate change to the city. In response, Greenpeace Canada Staff Lawyer Priyanka Vittal said: “The powerful testimonies delivered here today by Toronto youth, lawyers, residents and environmental experts leave no doubt that Torontonians want to see stronger climate action from City Hall. We’re happy to see Council take this first step in gathering the information needed to make sure that regular people aren’t on the hook for mounting climate-related costs. Protecting residents while holding polluters to account for their role in creating the climate crisis must be at the foundation of a just transition away from fossil fuels.” Read more at Greenpeace Canada

By Scott K. Johnson These plastics can easily be disassembled to chemical building blocks. Recycling sounds great in principle (because it is), but a frustrating number of devils lurk in the details. For example, while some materials like aluminum can readily be melted down and turned right back into new aluminum cans, recovered plastics tend to be lower quality than “virgin” material. That’s because recycled plastic retains some of its previous properties—like Lego bricks that can’t be separated. The next plastic you make won’t be exactly the same type, and the recycled material won’t fit perfectly into its new spot. Read more at Ars Technica
