the Most Abundant Material in Earth


The most abundant material on Earth didn’t have a name, and, in fact, hadn’t been seen — until now. For the first time ever, scientists have gotten their hands on a sample of bridgmanite, a mineral that is believed to make up more than a third of the volume of the Earth. In a new paper published in Science late last week, Oliver Tschauner of the University of Nevada, Las Vegas, and his team describe bridgmanite for the first time. [via]

AND

Formula: (Mg,Fe)SiO3. System: Orthorhombic. Name: Named in 2014 by Chi Ma and Oliver Tschauner in honor of Percy Williams Bridgman [April 21, 1882 Cambridge, Massachusetts, USA – August 20, 1961 Randolph, New Hampshire, USA], winner of the Nobel Prize for Physics in 1946 for his work in high-pressure physics.

Darwin’s dilemma solved

k

Natuurlijk staat de evolutietheorie van Darwin als een huis. Zoals dat altijd gaat met theorieën die miljarden jaren verklaren waren er nog wat plekken die ingevuld moesten worden. De explosie van leven die zo’n 530 miljoen jaar geleden plaatsvond is zo’n plek.
Onderzoekers van de University of Texas hebben ontdekt wat mogelijk de eindoplossing van Darwin’s Dillema is. Op de grens van het Precambrium en en Cambrium vonden enorme veranderingen in op tektonische gebied plaats. Daardoor verspreidde zich ondiep oceaanwater over de continenten, waardoor meercellig leven met skeletten mogelijk werden. De tektoniek zorgde ervoor dat zich tussen de oude continenten Laurentia (tegenwoordig Noord-Amerika) en Gondwanaland een instroomopening vormde. Daar stroomde voedselrijk oceaanwater binnen, dat voor ideale omstandigheden voor snellere evolutie zorgde.[TPO]

Kurtzgesagt – The Ebola Virus, How Your Body Fights For Survival


What does the Ebola virus actually do in your body? Why is it so dangerous and why does it kill so many people? We take a look at the apocalyptic war that rages in the body after an infection by the Ebola virus and the soldiers fighting.
Videos, explaining things. Like evolution, time, space, global energy or our existence in this strange universe.
We are a team of designers, journalists and musicians who want to make science look beautiful. Because it is beautiful.

Satelite Patrol for illegal fishing

Illicit fishing goes on every day at an industrial scale. But large commercial fishers are about to get a new set of overseers: conservationists—and soon the general public—armed with space-based reconnaissance of the global fleet. But now environmentalists are using sophisticated technology of their own to peel away that cloak of invisibility. With satellite data from SpaceQuest and financial and engineering support from Google, two environmental activist groups have built the first global surveillance system that can track large fishing vessels anywhere in the world:
Global Fishing Watch.
Oceana has begun using the tool internally to track vessels that have already been blacklisted for fishing illegally, Savitz said. “We can see vessels that appear to be fishing in protected marine areas. Government officials often know about this activity but don’t do anything about it. We’ll use the tool to shine light on this activity and produce public pressure for officials to actually do their jobs.” [Wired]
