THE QUOTE RACK

 Origins of a deadly fungus

Scientists are a step closer to untangling the origins of a deadly fungus that has been causing dangerous drug-resistant infections in hospitals in the U.S. and around the world.  Candida auris was discovered as a human pathogen about a decade ago, reports ScienceNews.org, and some 1,700 cases have since been reported in the U.S.  The superbug’s ability to thrive inside humans was a mystery, because most fungi cannot grow in such sweltering conditions.  That led scientists to suspect that C. auris originated and became accustomed to higher temperatures in tropical wetlands, which have warmed significantly in recent years because of climate change. Researchers struck gold in coastal wetlands on the remote Andaman Islands, about 200 miles south of Myanmar, finding C. auris at a site with no known human activity.  One sample was still sensitive to antifungals, suggesting that the fungus developed drug resistance inside humans.  The findings should help scientists undertake future studies of the superbug, and better understand its tolerance for higher temperatures and its resistance to antifungals.

Taxing the rich won’t suffice

Progressives are afraid of taxes.  To pay for trillion-dollar stimulus and infrastructure plans and expand the social safety net, Democrats always say they’re limiting their tax hikes to “the rich.”  But the trouble for the Left is that you can’t pay for the government they want by taxing only the rich.  Every social democracy in the world has far higher tax rates for the middle class than the U.S. Canada pays for its single-payer health-care system and extensive social safety net with a national 5 percent sales tax, provincial sales taxes of up to another 10 percent, and a top income-tax rate in Ontario of 46.13 percent on incomes of more than $175,000.   

In the U.K., taxpayers get hit with a 40 percent tax on incomes of just $52,100, and 45 percent at $208,600, without standard deductions.  That comes on top of a 20 percent value-added tax on all goods and services, and a $3-per-gallon gas tax.  In Denmark, the top tax rate of 55.9 percent kicks in at $86,500, and there’s a 25 percent value-added tax.  If progressives want a social democratic utopia, they’ll have to persuade middle-class Americans to pony up and pay for it.

Biden’s climate plan:  Is it realistic?

*****America is back in the global fight against climate change.  At a virtual summit of 40 world leaders last week, President Biden made an emphatic break from the Trump era, pledging to slash U.S. net carbon emissions to 50 percent of their 2005 levels by 2030, and 100 percent by 2050, with the entire U.S. energy sector achieving net zero carbon emissions by 2035.  Biden did his best to make his plan sound like a win-win for the American people, calling it an extraordinary engine of job creation and economic opportunity.  That’s unlikely to persuade hostile Republicans, however, and though Biden could nibble away at U.S. carbon emissions through executive orders, the greatest challenge his plan faces is that he needs Congress to pass it.

--Ella Nilsen, Vox.com

 *****Experts say that achieving such dramatic cuts in emissions will also require rapid and sweeping changes to virtually every corner of the nation’s economy.  Coal-fueled power plants, already a declining source of energy, will need to shut down.  The number of wind turbines and solar arrays would need to quadruple.   Most new cars will have to be electric.  It’s all achievable in theory, but success will mean a very different America.

-Brad Plumer, New York Times

 *****Thanks, but no thanks.  With 80 percent of our current energy coming from fossil fuels, Biden’s vision would mean a precipitous drop in the living standards of most citizens.  The cost of retrofitting every home, factory, warehouse, and building in America to run on electricity would cripple our economy.   We’d then need to envelop most of the nation in panels and windmills, presumably relying on Gaian prayer circles to ensure enough sunshine and wind to keep our country running.

--David Harsanyi, NationalReview.com 

*****Even in the unlikely event the U.S. could meet Biden’s targets, China, India, and other countries will merely pretend to go along.  Who’s going to hold China accountable for its climate pledges, and how, precisely?

­­ --Rich Lowry, Politico.com

*****Nonsense.  The costs of wind and solar power are already competitive with fossil fuels, thanks to an extraordinary innovation cycle that makes them cheaper every year.   As usual, conservatives are responding to the climate crisis with misinformation and a dismissive attitude toward doing anything.

Tech gives, but it also takes away

We are steadily losing the rights of ownership.  While packing for a move recently, I came upon a box of old DVDs.  But it was something more than nostalgia that made me balk at tossing them:  They were among the few possessions I actually owned. Through the proliferation of streaming, internet-based media and now even digital art, we consume more and more yet seem to have less and less.  Technological advancements not only weaken our connections—imagine, for instance, inheriting a grandparent’s e-books instead of their books—but also raise critical questions about the future of possession.  Farmers may spend hundreds of thousands of dollars on a fancy new John Deere tractor, but soon discover that only an approved dealer is allowed to fix it if it breaks.  U.S. law traditionally limits sellers’ ability to control what a customer does with their products, but courts have struggled with goods that did not exist in physical space.   This issue is gaining more urgency. Some cars now have devices that allow them to be disabled remotely in the case of a missed payment.  If this doesn’t feel frightening, consider that the precedent now being set with things like tractors could even mean that those with advanced prosthetics do not truly own their limbs.

Is that really ‘Nowheresville’?

Fake satellite imagery is a growing geopolitical concern.  “Deepfake” technology, which uses machine learning to superimpose altered footage on top of a video in a way that’s misleading or deceptive, has been widely discussed in other fields, such as political science.  Now geographers are raising the alarm about the potential for fake, AI-generated satellite imagery that could be used for propaganda—for instance, erasing prison camps or generating images of fake wildfires.  There is a long tradition of mapmaking deception; cartographers even used to insert fake settlements or “paper towns” into their maps to expose knockoffs.  Manipulated satellite imagery is particularly worrisome, however, because the resolutions are poor to begin with, and satellite images have gained broad public credibility.

Cybercrime's threats and attacks

The crippling of a major oil pipeline by hackers represents a new extreme in the global ransomware epidemic.  Colonial Pipeline, which supplies nearly half the fuel consumed on the East Coast, [recently] announced that hackers had attacked its internal computer network, and shut down parts of the pipeline’s operations to contain the threat.  Though the attack does not appear to have reached key control systems for the 5,500-mile conduit running from Texas to New Jersey, it is still one of the largest disruptions of American critical infrastructure by hackers in history.

--Andy Greenberg, Wired.com 

The Russian cybercrime group known as DarkSide claimed responsibility.  The DarkSide hackers are known for double extortion, simultaneously locking up networks and threatening to leak stolen data unless a ransom is paid. The group claims it is apolitical, but its activity reflects a pattern of Russia taking an indulgent approach to cybercrime targeting the West

--Eamon Javers, CNBC.com

 Nation states can easily hide behind criminal groups in this new form of cyberwarfare.  Attackers can simply use modified variants of ransomware commonly used by cybercriminals, keeping the real motives behind an attack hidden.

--Danny Palmer, ZDNet.com

One state that barely bothers to conceal its cybercrime ambitions is North Korea. In a country where few families own computers, North Korea has trained cybercriminal talent the way Olympians were once cultivated in the former Soviet bloc, placing the most promising pupils in specialized schools.It’s estimated that 7,000 North Koreans now work in the country’s “hacker army.” Some of their operations involve months of planning and sophisticated social engineering.  For one attack in Chile, a Spanish-speaking actor was hired to impersonate a real banking executive to gain access to the company’s network.

--Ed Caesar,  New Yorker 

These attacks are getting nastier.  Hackers [recently] paralyzed the digital resources at Scripps Health.  Survivors of the smuggling boat that capsized off Point Loma could not be sent to the closest trauma center, Scripps Memorial Hospital La Jolla, because its computer systems were down.

--Paul Sisson, San Diego Union-Tribune 

We can ill afford another wake-up call.  The vulnerability, in particular, of our energy infrastructure is one of the top-drawer issues of the 21st Century. Companies and the government have to start acting now to insulate our networks.  Part of that is being transparent after attacks, rather than holding on to information out of embarrassment or competitiveness. That only makes it harder to prepare for and surmount the next one.
