Our Weekly Science Picks: Surfing the Web Through Augmented Reality to Collapsing Dark Matter

Hi there – Marian Shivji here with your weekly dose of science facts and fascinations. This week features an injection of augmented reality into your web browser, up to a giant monument that converts air pollution into jewellery. Doctor’s orders below.

Your Web Browser’s Latest Plugin? Why, Augmented Reality Of Course!

Augmented reality (AR) is currently best-known for its gaming applications, such as the once ever popular Pokémon GoA new trend is now on the rise, however, of companies pushing this seamless blending of the digital and physical worlds for more mainstream purposes, as opposed to just the gaming novelty that AR is today. The latest innovation in AR comes from Google, who’s latest venture explores how to invigorate static content, such as a news article on mobile and PC web browsers, with AR. Google has dabbled in AR for the past few years now, through Tango and ARCore.  While Google has previously explored implementing AR into its own Chrome browser, the search engine giant is now looking to extend its cross-platform edge. This week, Google debuted the novel product Article, a 3D model viewer that can integrate AR into most web browsers. On mobile phones, an AR button appears when the user reads about an object that the browser can bring to life. Tapping this button activates the phone’s camera, allowing the user to project the object into the physical world, as represented by the space suit ‘object’ below. The Google blog post explained: “The unique power of AR is to blend digital content with the real world. So we can, for example, surf the web, find a model, place it in our room to see just how large it truly is, and physically walk around it.” Article will also allow such capabilities that were previously limited to devices like smartphones to be available on desktop computers. Article is just one in a series of prototypes and there’s a lot left to explore. As the AR matures, much more impressive applications will be unveiled, which could help the tech to go from novel to transformative.

Dark Matter May be More “Matter-Like” Than Once Thought

Our current understanding of dark matter is that it surrounds entire galaxies as spherical “halos” of invisible, unidentified massive, as illustrated by the blue surrounding the milky way above. This ‘featureless blob’ theory of dark matter’s existence is supported by the observation that an extra source of mass, astronomers can’t explain the motions of the stars in galaxies and why they move at the speeds they do. The ‘halo of mass’ version of dark matter might be only part of the story, however, as recent research by theoretical physicists Mathew Buckley and Anthony DiFranzo suggests that dark matter could collapse into smaller, more complex structures. This behaviour would render it more like the ‘normal’ matter that condenses into stars and planets. To collapse, dark matter would need a way to lose energy, slowing particles as gravity pulls them into the centre of the clump, so they can glom on to one another rather than zipping right through. The electromagnetic forces that dictate this process of energy loss for ‘normal’ matter have been ruled out for the most commonly proposed types of dark matter particles, such as weakly interacting massive particles (WIMPs). Buckley and DiFranzo imagined what might happen if an analogous “dark electromagnetism” allowed dark matter particles to interact and radiate energy in the form of dark photons, a dark matter analog to particles of light. In Buckley and DiFranzo’s scenario, it is unlikely that the dark matter can squish down to the size of a star and likely reach a point where they can’t lose any more energy long before then, rendering a single clump to be hundreds of light-years across. Thousands of clumps of dark matter could therefore be lurking, undetected in the halo surrounding our galaxy. The latest figure suggests that dark clumps constitute 10 percent of the Milky Way’s dark matter. By looking for the effects of unexplained gravitational tugs on stars, scientists may be able to determine whether galaxies are littered with dark matter clumps. “Because we didn’t think these things were a possibility, I don’t think people have looked,” Buckley says. “It was a blind spot.”

A Giant Smog-Sucking Hoover in Poland Converts Air Pollution into Jewellery


92% of the world’s population live in areas of poor air quality. Given that figure basically equates to the entire global population, tackling poor air quality could be a lucrative market. A giant air purifier created by the Dutch designer Daan Roosegaarde is currently being installed in a park in Kraków, Poland. Known as ‘the Smog Free Project’, the purifier stands at a whopping seven-metres and will be able to clean the air around the park at a rate of 30,000 cubic metres per hour whilst only consuming the same amount of electricity used by a water boiler. Most notably, the Smog Free Tower filters out the ultra-fine and very harmful PM2.5 particles – created by cars, tires and even trains – that can become lodged deep within the lungs. The tower took three years to develop and has been touring the world for the last two years. Its last year-long stay was in China, where it was shown to reduce air pollution by up to 55% in its surrounding area. While its functional use is clear, Roosegaarde also designed the purifier as a centrepiece for raising awareness around air pollution. Its stationing in Krawkow is as part of an exhibition that challenges our views on air pollution. As such, the fine carbon particles that are collected by tower can then be condensed into tiny cubes of ‘air pollution’ which can then be bought. As I said, lucrative.

MIA for 8 Decades, the Eastern Cougar is Now Officially Extinct


The eastern cougar once roamed the forests, mountains, and grasslands in every American state east of the Mississippi. For the past eight decades, however, the cougar has gone off grid. This led the US Fish and Wildlife Service (FWS) to open a review into the status of the mountain lion in 2011. After years of research, federal wildlife biologists finally concluded in 2015 that there was no scientific or physical evidence of a viable population left. The big cat had been on the Endangered Species Act since 1973 and at this point, the researchers recommended that the search for the cat be put to bed. This week finally saw that happen as the subspecies (Puma concolor cougaris now officially extinct. This declaration of extinction might – paradoxically – be a good thing. States that have been prevented from reintroducing animals from the western population for decades should now be allowed to do so. Large predators, such as the mountain lion, play a crucial role in the wider ecosystem. According to a recent paper detailing these benefits, not only do cougars reduce the number of ticks by killing deer, but they also save lives by reducing deer-car collisions. Putting it into perspective, if pumas were reintroduced across the US, collisions from deer-car incidents would likely be slashed by 22 percent, saving 115 people and preventing over 21,000 accidents, altogether saving the economy an impressive $2.12 billion.


Our Weekly Science Picks: France Transplants a Face While Capetown Braces for Water Crisis

Hello there– Marian Shivji here with your weekly round-up of the latest in science, data and peculiarities. This week features a double face transplant, a city on the brink of dystopia, and a look at how data and machine learning are currently being used for weird and wonderful purposes.

Surgeons in France Just Performed the First-Ever Double Face Transplant

Face transplants have the potential to tackle a wide-range of medical conditions from genetic disorders to assaults. Plights of the face can go beyond disfigurement to result in a loss of function, hindering one’s ability to breathe, eat or speak. Twelve years ago, a man from France became the first person to ever receive a facial transplant. Fast forward seven years, his body rejected the new face, leaving him without a suitable alternative ever since. In a risky move, surgeons decided to attempt a second face transplant, making the Frenchman the recipient of not only the first face transplant but now the first ever double face transplant. These operations are a risky game and by no means close to routine practice. Fewer than 40 face transplant operations have ever been performed, so statistics on long-term outcomes for patients are lacking. Since its introduction, six people have died from the facial procedure. Many medical experts believe that rejection will be an inevitable consequence of face transplants for the foreseeable future. As a preventative measure, patients must typically take immunosuppressive drugs for the rest of their lives after the procedure. A patient by the name of Isabelle Dinoire suffered rejection of her transplanted face, which caused her to lose feeling and usage of her lips. She later died of cancer in 2016, which was thought to have been caused by the immunosuppressant. It will still be weeks before doctors can determine whether this secondary transplant proves successful. If it is, it could give the other transplant recipients hope that further procedures could be an option in the case of chronic rejection.

In Less than 90 Days, Cape Town Could Become the First Major City to Run Out of Water

Cape Town and the surrounding region has been battling droughts for nearly three years now, resulting in a dangerous drop in the levels of its water-supplying dams. Located in a geologic bowl historically fed by heavy winter precipitation, the coastal South African metropolis was once regarded to be an abundant haven of natural water. Now, in less than 90 days, Cape Town might become the first major city in the world to run out of water. April 21 has been marked as the potential “Day Zero,” the day on which experts have predicted that the dams will drop below 13.5 percent of their combined capacity. With little rain on the horizon, the city’s mayor has impeded a “drought charge” in order to fund water recycling projects such as the construction of three desalination plants, which they hope to have in operation by March. The city has also enforced a water limit on its 3.7 million residents of 23 gallons per person per day, drastically cutting their water consumption.If these measures fail and the dystopian, Mad Max-like future prevails, all the city’s taps (except in the poorest neighbourhoods) could be shut off by April. Capetonians would be forced to queue for their daily ration of water of 25 litres (5.5 gallons) from one of 200 government-organized collection sites. This crisis arose from a few compounding factors. While the El Niño weather pattern exacerbated the earlier part of the drought in 2015, experts are now pointing towards poor city management, a growing urban population, and – rather unsurprisingly – climate change. The latter threatens many more “Day Zero” occurrences globally. Scientists have estimated that North Africa and the Middle East could become so hot and dry that they will be uninhabitable in the near future, even if the targets of the Paris climate agreement are met. Another study found that nearly three-quarters of the world’s population will experience life-threatening heatwaves by the end of this century. If nothing else, the Cape Town drought and its implications serve as a stark reminder that climate change is no longer a distant concern.

Pornhub’s Data Provides a Comedic Perspective of the False Missile Alert in Hawaii

How would you spend your last moments if you thought that you only had a few hours left to live? It’s the age-old question that many of us have considered from time to time, but that question became a reality for residents of Hawaii when a false missile alert was circulated last week. As you would expect, people panicked – rushing for the nearest shelters and following protocol to a T. As a follow-up question, what would we then expect people to do upon being told that everything was going to be fine after all? The website Pornhub” released data that paints a picture of the situation from start to finish. The minute the missile alert went out, Hawaii’s traffic to their website dropped by almost 80 percent of their usual Saturday levels. When the second message went out at 8:45am local time, the hilarity ensued. As it happens, Hawaiians celebrated the fallacy of the alarm by giving themselves a little love. By 9:01am, traffic to Pornhub then skyrocketed, with hits surpassing the usual Saturday by 50 percent. Whether this was truly out of celebration or as the island’s means to relieve stress after the looming threat of death would require further study. Though an unlikely suspect for event driven data analysis, this isn’t the first time Pornhub has released such data. A few weeks ago, the site scrutinised its traffic during the Great American Eclipse, which shows just how committed the Americans are to star gazing.

The AI That Prepared Astronauts for Space Revolutionises Crime Fighting in Belgium

The Artificial intelligence systems that were created to prepare astronauts for space now provide a promising approach for solving crimes here on earth. The Space Applications Services company developed the software for astronauts-in-training in the European Space Agency (ESA) Columbus research laboratory, which had them respond to queries such as “What is this?” and “Where is this?” The origins of this machine-intelligence date back almost 15 years. The technology has advanced rapidly since, leading to the recent engineering of an intelligent mobile crew assistant. This bot is scheduled to undergo testing later in 2018 with Alexander Gerst, the next ESA astronaut to be sent into space. The potential for AI to reduce ground operations and associated costs, as well as the possibility that it could lower risks for human personnel has been paramount for space agencies. While that initial crew training project of 2003-05 is a relatively small step in artificial intelligence, the same integrated approaches to machine learning are now leading to feats in a completely different domain: security. Space Applications Services began to pivot the AI toward security applications when it developed a tool that allowed it to answer most factual questions and to display the results visually. The technology does the laborious parts of a crime analyst’s job with a single click. For instance, the machine intelligence became capable of combing through thousands of hours of security camera footage and pulling up specific video feeds upon request. Further sources of data that can be semi-automatically scanned by the software include written records, footage and social media – all within seconds. It can detect suspicious patterns, reconstruct scenes and highlight promising avenues of investigation. Belgian police are currently evaluating software for cost-effectiveness which could become a commercial product by the middle of this year. Belgium is just the latest country to use the hottest tech on the market to keep its citizens safe, following in the footsteps of China and Dubai.

Top Story: New York Disinvests then Sues Five of the World’s Largest Oil Companies

Good morning – it’s Marian Shivji here with the first of many weekly digests from us here at Crowd.Science. We will be using this opportunity to round-up the hottest topics circulating the world of science and crowdfunding so that we can deliver it all to you in one handy blog.

Bill de Blasio is done paying for climate change. The NYC mayor made an official announcement early last week that the city will be the first to divest the entirety of its pension funds – a total of $191 billion – from fossil fuels. This funneling away of $5 billion worth of investment from fossil fuel is reportedly the largest of any municipality to date. This stride brings the overall disinvestment movement’s value to exceed a whopping $6 trillion, making it, arguably, the fastest growing campaign of its kind in history. In conjunction with withdrawing funds, the city triggered full-blown legal action against ExxonMobil, Chevron, BP, Royal Dutch Shell, and ConocoPhillips. The city is asking that they pay for the defensive measures the metropolis is having to put in place to stave off climate-associated damage, claiming each was involved in harming the environment by continuing to burn fuel despite knowing its harmful effects and “intentionally misled the public to protect their profits.”

Speaking of climate change decimating our current living situation…

More Water on Mars!

We already knew of water’s existence on Mars, but recent research highlights just how close a significant amount of water ice is to the surface in mid-latitude regions on Mars. This discovery could be paramount for future exploration missions to Mars, allowing astronauts to use such ice for water and fuel. A lack of craters in the ice also hints that they are extremely young – relatively speaking – being less than a million years old. Further, the ice appears to be layered, much like the sedimentary layers on Earth, which could therefore elucidate different geological periods in the history of the planet. The findings were led by Colin Dundas from the US Geological Survey in Arizona. The team writes, “this ice… is expected to preserve a record of climate history, influences the planet’s habitability, and may be a potential resource for future exploration”.

Bill Gates Thinks Cancer Therapies Could Serve a Much Wider Purpose

In 2016, an estimated 445,000 people died from malaria, 1 million from HIV-related illness, and 1.7 million from TB (including 0.4 million with HIV). If the immunotherapy used to treat cancer patients in the world’s more prosperous nations could eventually be used to control infectious diseases in its poorest, whilst helping to treat those already infected, we could see a significant decline in these figures. But cancer research is just the start when it comes to using the solutions of “rich-world markets” to address the ailments of the poorest. For example, research into neurodegenerative diseases such as Alzheimer’s could be useful for treating the hundreds of millions of children with cognitive development issues due to growing up in poverty, while researchers in Africa and South Asia attempting to address mal​nutrition may glean valuable insights from obesity research. This was the message of Bill Gates’ keynote address at J.P. Morgan’s Annual Healthcare Conference in San Francisco. As Gates concluded, reaching this goal of health equity in our lifetime by building bridges between the private sector and global health isn’t just a possibility — it’s an imperative.

Lastly, we go to a group of Brazilian biologists with a penchant for literary fantasies…

Seven New Species of Spider Discovered – Seven Opportunities to Nail the Name

Seven new species of cave spiders were discovered by a team of Brazilian arachnid biologists in a system of caves formed of iron-rich sediment deposits in the state of Pará. All seven spiders are of edaphic trogophile decent​, meaning that they live in dirt and have adapted to spending all their time in caves. The group’s paper, represents five years of work studying the spiders in the field and the collection of approximately 2,000 specimens. These biologists may also have a flare for literature and popular culture, given the names of these new creatures. The first two were “namely” inspired from J.R.R. Tolkien, being Ochyrocera laracna and Ochyrocera ungoliant. The first monstrous arachnid is named for Laracna, the Portuguese translation of Shelob, a giant cave spider and immortal ancient creature that guards one of the passages into Mordor. The second is named for Shelob’s mother, Ungoliant, the primordial spider who “desir[ed] only to be a mistress of her own insatiable craving to devour all light, to feed her everlasting emptiness.” A third spider, Ochyrocera varys was named after Lord Varys from the A Song of Ice and Fire series by George R. R. Martin. Varys, a master of espionage, who is called the Spider because of his skill at cultivating a web of informants.
