When’s The Last Time You Thought About The Revolving Door? This Modest Invention—something You Likely

The Most Metal Mass Extinction Events, Ranked

in the style of The Toast

That One Unnamed Extinction Event That Happened When Blue-Green Algae Discovered Photosynthesis and Started Pumping the Environment Full of Oxygen, Which Was Toxic to All Other Life on Earth at That Point in Time

This extinction event did result in the extinction of more living organisms than any other, whether you rank by number of individuals, number of orders/genera/species, % of life, or amount of biomass, but they were all single-celled organisms, so they don’t even register on the metal scale.

The Current Slow Slide Due to Anthropogenic Environmental Modification

Habitat destruction isn’t very metal.

Late Devonian

Some super-weird shit died out, which is totally metal, but we have no idea why, which isn’t. It might not even have been an extinction event, just a decrease in the speciation rate. Jawed vertebrates totally unaffected.

End Ordovician

Second-largest extinction event after the End Permian (not counting those blue-green algae fuckers). Caused by tectonic plate shifting (kinda metal) and resulting glaciation (mildly metal).

Deep Impact

Pros: Giant asteroid hitting the earth.

Cons: Fictional.

End Triassic

Probably caused by massive volcanic eruptions, which is pretty metal, but mostly just wiped out some weird looking amphibians, which is only mildly metal.

End Permian

Greatest extinction event of all time (with the exception of that blue-green algae fiasco mentioned above), wiping out ~95% of all species: metal. Only known mass extinction of insects: metal. Probably caused by the biggest volcanic eruptions since life began (metal) which ignited massive coal beds (metal) and caused the release of methane from the ocean floor (metal) resulting in a runaway greenhouse effect that raised the average ocean temperature to 40C for several million years, essentially boiling the earth alive (super metal). Paved the way for dinosaurs to take over the earth: metal. Known as the ‘Great Dying’: totally metal.

However, most of the extinctions occurred in sessile marine organisms, which are way too boring to be metal, and for the first ~20 million years after the extinction event, land was dominated by Lystrosaurus, which is the most un-metal looking reptile you can think of.

End Cretaceous, aka the K-T Event

A GIANT FLAMING BALL OF ROCK HIT THE EARTH AND KILLED ALL THE (non-avian) DINOSAURS. ENOUGH SAID.

Shaken: cocktail kits by mail

Shaken is a UK startup that sells subscriptions to “the best cocktails you’ve ever made.” Every month, they send you a handsome box with several bottles of rare and delicious booze, small-batch bitters, and a cocktail recipe explaining the history, chemistry and practice of some classic or novel cocktail.

You bring this stuff into your kitchen and play with it, mixing drinks according to the recipe or its variants, or your taste, according to your preference. They supply everything except ice, fruit, shakers and glassware, and each box has enough booze for four drinks.

The Shaken folks took over my old offices in London when I moved to LA this summer and I got to try some of their packages before I left. They turned me on to what is literally some of the best booze I’ve ever drunk (particularly the Plantation rums, which are finished in Cognac casks and taste like nothing you’ve ever tried before – there’s one that finishes exactly like a smoky Islay, which is indescribably brilliant).

Shaken doesn’t assume that you’re a hardcore cocktail fan, and the recipes are simple to follow. But they strike a great balance for people who want to go beyond, with ideas for refining and improving the basic recipe.

The boxes are no-obligation and you can skip a box any time you feel like it.

Africa, still covered in large swathes of pristine wilderness, is likely to lose much of its biological wealth if dozens of new massive development projects—from highways to railroads to pipelines—get the green light, according to a new study. Most of the projects are designed to increase agricultural production and ease the transport of minerals such as iron and coal. Yet if all are built, they’ll create a spider web of some 53,000 kilometers of corridors through deserts, forests, and savannas—and a host of environmental disasters, scientists say. Even worse, they contend, most won’t help the continent feed its people, even though this is the primary justification behind many of the projects.

“Africa is undergoing the most dramatic era of development it’s ever experienced,” says William Laurance, an ecologist at James Cook University, Cairns, in Australia, and the study’s lead author. “No one disputes its need for food and economic development. But these corridors need to be built without creating environmental crises.”

The scientists’ study is a follow-up to aprevious one they published last year inNature warning about the unprecedented number of road and transportation projects being planned globally. 

Paint job transforms walls into sensors, interactive surfaces

Smart walls react to human touch, sense activity in room

Walls are what they are – big, dull dividers. With a few applications of conductive paint and some electronics, however, walls can become smart infrastructure that sense human touch, and detect things like gestures and when appliances are used.

Researchers at Carnegie Mellon University and Disney Research found that they could transform dumb walls into smart walls at relatively low cost – about $20 per square meter – using simple tools and techniques, such as a paint roller.

These new capabilities might enable users to place or move light switches or other controls anywhere on a wall that’s most convenient, or to control videogames by using gestures. By monitoring activity in the room, this system could adjust light levels when a TV is turned on or alert a user in another location when a laundry machine or electric kettle turns off.

“Walls are usually the largest surface area in a room, yet we don’t make much use of them other than to separate spaces, and perhaps hold up pictures and shelves,” said Chris Harrison, assistant professor in CMU’s Human-Computer Interaction Institute (HCII). “As the internet of things and ubiquitous computing become reality, it is tempting to think that walls can become active parts of our living and work environments.”

Making an impact

ESA - Clean Space Programme logo. 25 September 2015 When a rocket is launched into space it crosses all layers of the atmosphere and interacts with them. How much impact does a launch have on the atmosphere and can we quantify the effect in such a way that we can take mitigation measures? These are only a few of the questions raised by the Clean Space AtILa (Atmospheric Impact of Launchers) project. Neil Murray explains: “It is difficult to use computer modelling to precisely monitor what happens when a rocket is launched as the size of the plume is far smaller than the scale of the climate models that we use to model the atmosphere”.

Picture perfect liftoff

Therefore two strategies were worked out to model the impact, one started from the size of the plume and this was allowed to develop over time and space to the size of the climate model and used as the boundary conditions of the climate model. Another strategy started from the size of the larger model and introduced sub-grid models which modelled the plume within the climate model grids. Both models gave surprisingly similar results. So far it has been thought that chlorine, which is converted from the oxidizer (ammonia perchlorate) in the solid booster fuel mixture, has had the main effect on ozone depletion in the immediate area where the plume is emitted.

Computations conducted at ONERA using the CEDRE code

The latest studies have shown that alumina particles, i.e., oxidised aluminium, which is also present in the solid rocket fuel, may also have a significant ozone depletion effect depending on the particle size. “If the particles are on the micrometer scale they would quickly fall out of the sky and have little impact on the atmosphere. However, the smaller the particles, the higher their combined surface area and the longer they remain suspended in the air, which means that their potential catalytic effect in ozone reduction could also be much higher.” Therefore it is imperative that quantitative data is collected to be able to accurately measure and predict the impact by mathematical models.

Computations conducted at ONERA using the CEDRE code

The first step towards quantitative data is the kick-off of an activity organised in cooperation with DLR whereby a solid rocket motor model in a wind tunnel will be used to simulate the evolution of particles in a representative rocket chamber and to then interpolate this to the conditions at launch. From these measurements accurate models will be developed for predicting the development of alumina particles under real launch conditions. So why not just use real launch data? “It is not that easy to make these measurements during a real launch and so far no data has been collected for European launchers. Up to now we have mainly been relying on data measured by NASA during launches in the 1990s, however, the representativeness of this data with respect to European launchers is questionable. This ultimately leaves us with the task of somehow collecting such flight data and it is something that we are discussing at length.“ 

Ariane 5 ECA V184 climbout

"Even when we are able to make real-time measurements during a launch it still is a large task to interpret this data correctly and extrapolate this to all launches, as daily changes in the atmosphere and the time of the launch are just a few parameters that severely influence the effect. Luckily we are working with some of Europe’s experts in climatology!” The AtILa project aims to understand the impact of launching its rockets into space by modelling the rocket plumes from their origin in the rocket chamber up to their impact on a global scale using climate models. This is one of the projects that ESA carries out under the Clean Space initiative which has carried out life cycle assessments for the space industry in order to monitor the effect of each space project on the environment. Implementing eco-design strategies into every phase of a space project is the ultimate aim of this initiative.

Greenland is Melting Away

This river is one of a network of thousands at the front line of climate change.

 By NYTimes: Coral Davenport, Josh Haner, Larry Buchanan and Derek Watkins                                    

On the Greenland Ice Sheet — The midnight sun still gleamed at 1 a.m. across the brilliant expanse of the Greenland ice sheet. Brandon Overstreet, a doctoral candidate in hydrology at the University of Wyoming, picked his way across the frozen landscape, clipped his climbing harness to an anchor in the ice and crept toward the edge of a river that rushed downstream toward an enormous sinkhole.

If he fell in, “the death rate is 100 percent,” said Mr. Overstreet’s friend and fellow researcher, Lincoln Pitcher.

But Mr. Overstreet’s task, to collect critical data from the river, is essential to understanding one of the most consequential impacts of global warming. The scientific data he and a team of six other researchers collect here could yield groundbreaking information on the rate at which the melting of the Greenland ice sheet, one of the biggest and fastest-melting chunks of ice on Earth, will drive up sea levels in the coming decades. The full melting of Greenland’s ice sheet could increase sea levels by about 20 feet. [bold/itals mine]

“We scientists love to sit at our computers and use climate models to make those predictions,” said Laurence C. Smith, head of the geography department at the University of California, Los Angeles, and the leader of the team that worked in Greenland this summer. “But to really know what’s happening, that kind of understanding can only come about through empirical measurements in the field.”

For years, scientists have studied the impact of the planet’s warming on the Greenland and Antarctic ice sheets. But while researchers have satellite images to track the icebergs that break off, and have created models to simulate the thawing, they have little on-the-ground information and so have trouble predicting precisely how fast sea levels will rise.

Dire report by three excellent Times journalists covering a team of researchers camped out on the icesheets of Greenland. The conclusion is that glaciers and land ice are melting at rates far higher than scientists anticipated, or that climate models have shown. This means that sea levels are rising faster than projected, and many coastal communities are in grave danger.

The economic impacts are incalculable.

Nope.

How To Avoid The Next Atlantis

They say nothing in life is guaranteed except death and taxes. Maybe we should add rising sea levels to that list?

The lapping waves of Earth’s oceans are going to move as much as 1 full meter higher within our lifetimes, and perhaps several meters more in the coming centuries depending on what we do or don’t do about slowing down climate change. Part of this comes from melting glaciers and ice shelves flowing out to sea, and part comes from the natural expansion of water as it warms, but we have to face facts: Sea level is rising.

This new video from MinuteEarth looks at some of the interesting ways that coastal cities around the globe are trying to get ready for a wetter world. I wish this wasn’t something we had to prepare for, but I’m glad we’ve got smart people on the job.

A Tree of Life For 2.3 MILLION Species! 

This week, scientists released this massive tree of life showing the evolutionary relationships between 2.3 million different species, encompassing every scale of life from bacteria to blue whales. This massive undertaking combines more than 500 previous trees into one, the result being the largest and most complete tree of evolutionary relationships as we know them today. 

Like evolution itself, this diagram will continue to evolve as scientists fill in gaps and uncover more detailed information on the genetic relationships of Earth’s various species, but it’s not too shabby for a first draft. You can read more from Rachel Feltman at The Washington Post.

This type of wheel-like diagram is called a Hillis plot, one of my favorite ways of illustrating the tree of life. I’ve even found one drawn on an actual tree:
