“artificial rainforest” in Dubai

I continue to think that places like Dubai and Singapore with extremely inhospitable climates are preparing humanity for its future in space. They are creating cities that consist of climate-controlled high rise apartments, office buildings, malls, and indoor parks, all connected by subway lines, so there is really no reason to go outside. It’s not too hard to imagine transferring one of these cities to Mars.

the gates of hell

It’s October, time for a Halloween-related post or two. Here’s an interesting article on 11 places rumored to have entrances to the underworld. Most seem to be in exotic places, but it’s nice to see central Pennsylvania represented. I do think they have overlooked Centralia, Pennsylvania though, where people have been known to literally fall into pits of unquenchable underground fire. It is interesting that a wide variety of cultures and religions, from the Ancient Greeks and Romans to Christians and Buddhists and other Asian traditions, have had somewhat similar concepts of an underworld.

Zuckerberg vs. disease

Mark Zuckerberg and his wife have decided to set a modest goal of curing all disease.

Facebook co-founder Mark Zuckerberg and his wife, Priscilla Chan, on Wednesday announced a $3 billion effort to accelerate scientific research with the wildly ambitious goal of “curing all disease in our children’s lifetime.”

The many components of the initiative include creating universal technology “tools” based on both traditional science and engineering on which all researchers can build, including a map of all cell types, a way to continuously monitor blood for early signs of illness, and a chip that can diagnose all diseases (or at least many of them). The money will also help fund what they referred to as 10 to 15 “virtual institutes” that will bring together investigators from around the world to focus on individual diseases or other goals — an idea that has the potential to upend biomedical science…

facts and figures on illegal immigrants

The Week has some surprising facts and figures on illegal immigrants in the U.S. Just for fun, I’ll state it in the form of a quiz:

  1. About how many illegal immigrants are there, and what percentage of the U.S. population is that?
  2. What percentage of illegal immigrants here now have been here for more than 10 years?
  3. Is the number of illegal immigrants increasing or decreasing?
  4. What percentage of illegal immigrants are Mexican?
  5. Obviously, “illegal immigrant” means they crossed the border illegally, right?
  6. What percentage work? What percentage pay taxes? What percentage are receiving public assistance?
  7. What percentage have committed criminal offenses?

Answers (and I’ll repeat the questions, because it would be annoying if I didn’t):

  1. About how many illegal immigrants are there [Answer: 11 million], and what percentage of the U.S. population is that [Answer: 3.5%]?
  2. What percentage of illegal immigrants here now have been here for more than 10 years? [Answer: 66%]
  3. Is the number of illegal immigrants increasing or decreasing? [Answer: decreasing, from a peak of about 12 million in 2007. ]
  4. What percentage of illegal immigrants are Mexican? [Answer: 50%]
  5. Obviously, “illegal immigrant” means they crossed the border illegally, right? [Wrong: about 60% did, but 40% entered legally and overstayed their visas]
  6. What percentage work? [Answer: 73%] What percentage pay taxes? [Answer: 50%] What percentage are receiving public assistance? [Answer: 0% of adults, although children who are not citizens may receive public schooling and emergency medical care]
  7. What percentage have committed criminal offenses? [Answer: 7.5%]

cyber warfare

Critical parts of the internet in the U.S. are being systematically probed by foreign government hackers, according to one security expert.

Recently, some of the major companies that provide the basic infrastructure that makes the Internet work have seen an increase in DDoS attacks against them. Moreover, they have seen a certain profile of attacks. These attacks are significantly larger than the ones they’re used to seeing. They last longer. They’re more sophisticated. And they look like probing. One week, the attack would start at a particular level of attack and slowly ramp up before stopping. The next week, it would start at that higher point and continue. And so on, along those lines, as if the attacker were looking for the exact point of failure.

The attacks are also configured in such a way as to see what the company’s total defenses are. There are many different ways to launch a DDoS attack. The more attack vectors you employ simultaneously, the more different defenses the defender has to counter with. These companies are seeing more attacks using three or four different vectors. This means that the companies have to use everything they’ve got to defend themselves. They can’t hold anything back. They’re forced to demonstrate their defense capabilities for the attacker…

Who would do this? It doesn’t seem like something an activist, criminal, or researcher would do. Profiling core infrastructure is common practice in espionage and intelligence gathering. It’s not normal for companies to do that. Furthermore, the size and scale of these probes — and especially their persistence — points to state actors. It feels like a nation’s military cybercommand trying to calibrate its weaponry in the case of cyberwar. It reminds me of the US’s Cold War program of flying high-altitude planes over the Soviet Union to force their air-defense systems to turn on, to map their capabilities.

30% of African elephants gone in 7 years

A project called The Great Elephant Census has this shocking statistic.

Continent-wide survey reveals massive decline in African savannah elephants

African elephants (Loxodonta africana) are imperiled by poaching and habitat loss. Despite global attention to the plight of elephants, their population sizes and trends are uncertain or unknown over much of Africa. To conserve this iconic species, conservationists need timely, accurate data on elephant populations. Here, we report the results of the Great Elephant Census (GEC), the first continent-wide, standardized survey of African savannah elephants. We also provide the first quantitative model of elephant population trends across Africa. We estimated a population of 352,271 savannah elephants on study sites in 18 countries, representing approximately 93% of all savannah elephants in those countries. Elephant populations in survey areas with historical data decreased by an estimated 144,000 from 2007 to 2014, and populations are currently shrinking by 8% per year continent-wide, primarily due to poaching. Though 84% of elephants occurred in protected areas, many protected areas had carcass ratios that indicated high levels of elephant mortality. Results of the GEC show the necessity of action to end the African elephants’ downward trajectory by preventing poaching and protecting habitat.

It’s heartbreaking for at least two reasons. The obvious one is the elephants themselves because they are such a charismatic, iconic species. The African savannah ecosystem more broadly is iconic and its loss is also deeply disturbing. This is an example of a problem that probably almost everyone can understand and agree on, and yet our species is not solving it. It’s hard to have hope that we can solve the more complex and controversial problems if we can’t solve this one. It’s going to be a sad day when we realize the wild elephants are gone, possibly a sort of psychological tipping point for our civilization’s relationship with nature.

oil discoveries at 70 year low

Here’s a long article from Bloomberg called Oil Discoveries at 70-Year Low Signal Supply Shortfall Ahead. The basic thesis is that prices are so low companies have stopped looking for new oil, and ones existing supplies start to run out prices will rise.

Explorers in 2015 discovered only about a tenth as much oil as they have annually on average since 1960. This year, they’ll probably find even less, spurring new fears about their ability to meet future demand.

With oil prices down by more than half since the price collapse two years ago, drillers have cut their exploration budgets to the bone. The result: Just 2.7 billion barrels of new supply was discovered in 2015, the smallest amount since 1947, according to figures from Edinburgh-based consulting firm Wood Mackenzie Ltd. This year, drillers found just 736 million barrels of conventional crude as of the end of last month.

That’s a concern for the industry at a time when the U.S. Energy Information Administration estimates that global oil demand will grow from 94.8 million barrels a day this year to 105.3 million barrels in 2026. While the U.S. shale boom could potentially make up the difference, prices locked in below $50 a barrel have undercut any substantial growth there.

How soon will this have an effect? 2025 according to one source cited in this article, 2040 according to another. That seems pretty far out to me to make precise predictions. Hopefully we will have a cheap, reliable renewable energy source by then. But maybe we will have explosive population and consumption growth. Or maybe the world economy will tank. It’s just hard to say. I’m not snapping up oil stocks just yet.

Ford

Ford seems to be waking up to the possibilities of self-driving cars and integrated multi-modal transportation.

The century-old automaker will buy San Francisco shuttle startup Chariot and expand its services nationally and internationally. Ford also will team up with New York bike-sharing firm Motivate to bring its services to more cities throughout the Bay Area, with the goal of providing 7,000 bikes in the region by the end of 2018, up from the current 700. Riders will be able to access those bikes, as well as shuttles from Chariot, through an online service called FordPass.

“We’re taking a look at the whole ecosystem of moving people around,” Fields said in an interview Friday.

Better late than never. I was wondering if any of the Detroit companies would wake up and join forces with the tech industry, rather than just continuing to fade into irrelevance and obsolescence until one day they are gone and nobody cares. Are GM and Chrysler going to follow or are they just hoping for a government bailout every once in awhile?
