Scientists hope to breed sheep that emit less greenhouse gases

Here's looking at you, Babe.

Scientists are working to breed sheep that produce less greenhouse gases in order to reduce their impact on the environment.

The Grass to Gas initiative will combine international scientific and industry expertise to measure two major factors affecting the environmental consequences of the livestock – feed efficiency and methane emissions.

Its goal is to develop ways to identify animals with a lower impact, which can then be selected for breeding programmes.

Nicola Lambe, a sheep geneticist at Scotland’s Rural College (SRUC), said: “The reduction in greenhouse gas emissions is a global issue requiring a transnational and transdisciplinary approach.

“It will also contribute towards addressing the argument about the effect of eating meat on global warming, with sheep making use of land often unsuitable for other agricultural production, except conifers – at least in the UK.”

The research led by SRUC will use lambs bred from male sheep – known as sires – sourced from the Texel Sheep Society’s Texelplus programme, to investigate the effects of sire and breeding values on these measurements.

Data will also be analysed to quantify the economic and environmental benefits of improvements in feed efficiency and reduced greenhouse gas emissions.

Special Report – Inside the UAE’s secret hacking team of U.S. mercenaries

Two weeks after leaving her position as an intelligence analyst for the U.S. National Security Agency in 2014, Lori Stroud was in the Middle East working as a hacker for an Arab monarchy.

She had joined Project Raven, a clandestine team that included more than a dozen former U.S. intelligence operatives recruited to help the United Arab Emirates engage in surveillance of other governments, militants and human rights activists critical of the monarchy.

Stroud and her team, working from a converted mansion in Abu Dhabi known internally as “the Villa,” would use methods learnt from a decade in the U.S intelligence community to help the UAE hack into the phones and computers of its enemies.

Stroud had been recruited by a Maryland cybersecurity contractor to help the Emiratis launch hacking operations, and for three years, she thrived in the job. But in 2016, the Emiratis moved Project Raven to a UAE cybersecurity firm named DarkMatter. Before long, Stroud and other Americans involved in the effort say they saw the mission cross a red line: targeting fellow Americans for surveillance.

“I am working for a foreign intelligence agency who is targeting U.S. persons,” she told Reuters. “I am officially the bad kind of spy.”

The story of Project Raven reveals how former U.S. government hackers have employed state-of-the-art cyber-espionage tools on behalf of a foreign intelligence service that spies on human rights activists, journalists and political rivals.

The operatives utilized an arsenal of cyber tools, including a cutting-edge espionage platform known as Karma, in which Raven operatives say they hacked into the iPhones of hundreds of activists, political leaders and suspected terrorists. Details of the Karma hack were described in a separate Reuters article today.

An NSA spokesman declined to comment on Raven. An Apple spokeswoman declined to comment. A spokeswoman for UAE’s Ministry of Foreign Affairs declined to comment. The UAE’s Embassy in Washington and a spokesman for its National Media Council did not respond to requests for comment.

The Raven story also provides new insight into the role former American cyberspies play in foreign hacking operations. Within the U.S. intelligence community, leaving to work as an operative for another country is seen by some as a betrayal. “There’s a moral obligation if you’re a former intelligence officer from becoming effectively a mercenary for a foreign government,” said Bob Anderson, who served as executive assistant director of the Federal Bureau of Investigation until 2015.

While this activity raises ethical dilemmas, U.S. national security lawyers say the laws guiding what American intelligence contractors can do abroad are murky. Though it’s illegal to share classified information, there is no specific law that bars contractors from sharing more general spycraft knowhow, such as how to bait a target with a virus-laden email.

The rules, however, are clear on hacking U.S. networks or stealing the communications of Americans. “It would be very illegal,” said Rhea Siers, former NSA deputy assistant director for policy.

Now Your Groceries See You, Too

Walgreens is exploring new tech that turns your purchases, your movements, even your gaze, into data.

Walgreens is piloting a new line of “smart coolers”—fridges equipped with cameras that scan shoppers’ faces and make inferences on their age and gender. On January 14, the company announced its first trial at a store in Chicago in January, and plans to equip stores in New York and San Francisco with the tech.

Demographic information is key to retail shopping. Retailers want to know what people are buying, segmenting shoppers by gender, age, and income (to name a few characteristics) and then targeting them precisely. To that end, these smart coolers are a marvel.

If, for example, Pepsi launched an ad campaign targeting young women, it could use smart-cooler data to see if its campaign was working. These machines can draw all kinds of useful inferences: Maybe young men buy more Sprite if it’s displayed next to Mountain Dew. Maybe older women buy more ice cream on Thursday nights than any other day of the week. The tech also has “iris tracking” capabilities, meaning the company can collect data on which displayed items are the most looked at.

Crucially, the “Cooler Screens” system does not use facial recognition. Shoppers aren’t identified when the fridge cameras scan their face. Instead, the cameras analyze faces to make inferences about shoppers’ age and gender. First, the camera takes their picture, which an AI system will measure and analyze, say, the width of someone’s eyes, the distance between their lips and nose, and other micro measurements. From there, the system can estimate if the person who opened the door is, say, a woman in her early 20s or a male in his late 50s. It’s analysis, not recognition.

The distinction between the two is very important. In Illinois, facial recognition in public is outlawed under BIPA, the Biometric Privacy Act. For two years, Google and Facebook fought class-actions suits filed under the law, after plaintiffs claimed the companies obtained their facial data without their consent. Home-security cams with facial-recognition abilities, such as Nest or Amazon’s Ring, also have those features disabled in the state; even Google’s viral “art selfie” app is banned. The suit against Facebook was dismissed in January, but privacy advocates champion BIPA as a would-be template for a world where facial recognition is federally regulated.

Walgreens’s camera system makes note only of what shoppers picked up and basic information on their age and gender. Last year, a Canadian mall used cameras to track shoppers  and make inferences about which demographics prefer which stores. Shoppers’ identities weren’t collected or stored, but the mall ended the pilot after widespread backlash.

The smart cooler is just one of dozens of tracking technologies emerging in retail. At Amazon Go stores, for example—which do not have cashiers or self-checkout stations—sensors make note of shoppers’ purchases and charge them to their Amazon account; the resulting data are part of the feedback loop the company uses to target ads at customers, making it more money.

How to tax the rich

DURING HIS lesser-known run for president, which began in 1999, Donald Trump proposed levying a wealth tax on Americans with more than $10m. He may soon find himself campaigning on the other side of the issue. That is because Democrats are lining up to find ways to tax the rich. Senator Elizabeth Warren, who wants Mr Trump’s job, has called for an annual levy of 2% on wealth above $50m and of 3% on wealth above $1bn. Alexandria Ocasio-Cortez, a prominent new left-wing congresswoman, has floated a top tax rate of 70% on the highest incomes.

In one way these proposals are a relief. Left-wing Democrats have plenty of ideas for new spending—Medicare for all, free college tuition, the “Green New Deal”—that would need funding. Mainly because America is ageing, but also boosted by Mr Trump’s unfunded tax cuts, the debt-to-GDP ratio is already expected to nearly double over the next 30 years. If a future Democratic administration creates new spending programmes while maintaining existing ones, higher taxes will be necessary.

If revenues are to rise, there are good grounds to look first to the rich. Mr Trump’s tax cuts are just the latest change to have made life at the top more splendorous. Between 1990 and 2015 the real income of the top 1% of households, after taxes and transfers, nearly doubled. Over the same period middle incomes grew by only about a third—and most of that was thanks to government intervention. Globalisation, technological change and ebbing competition have all helped the rich prosper in recent decades. Techno-prophets fear that inequality could soon worsen further, as algorithms replace workers en masse. Whether or not they are right, the disproportionate gains the rich have already enjoyed could justify raising new revenues from them.

Unfortunately, the proposed new schemes are poorly designed. Ms Warren’s takes aim at wealth inequality, which has also risen dramatically. It is legitimate to tax wealth. But Ms Warren’s levy would be crude, distorting and hard to enforce. A business owner making nominal annual returns of around 5% would see much of that wiped out, before accounting for existing taxes on capital. That prospect would squash investment and enterprise. Meanwhile, bureaucrats would repeatedly find themselves having to value billionaires’ art collections and other illiquid assets. Eight rich countries have scrapped their wealth taxes since 1990, often amid concerns about their economic and administrative costs. In 2017 only four levied them.

There are better ways to raise taxes on capital. One is to increase inheritance tax, an inequality-buster that, though also too easily avoided, is relatively gentle on investment and work incentives when levied at modest rates. Another is to target economic rents and windfalls that inflate investment returns. Higher property taxes can efficiently capture some of the astronomical gains that landowners near successful cities have enjoyed. It is also possible to raise taxes on corporations that enjoy abnormally high profits without severely inhibiting growth. The trick is to shield investment spending by letting companies deduct it from their taxable profit immediately, rather than as their assets depreciate. (Mr Trump’s reform accomplished this, but only partially and temporarily.)

What about income tax? Ms Ocasio-Cortez’s boosters point out that a 70% levy is close to the rate that is said to maximise revenue in one notable economic study. In truth the study is notable because it is an outlier—one that ignores the benefits of entrepreneurial innovation or of workers improving their skills. France’s short-lived 75% top tax rate, which was scrapped at the end of 2014, raised less money than was hoped. America’s top rate of federal income tax is 37%; higher is clearly feasible, but it would be wise to keep change incremental.

Although there is scope to raise taxes on the rich, they cannot pay for everything, if only because the rich are relatively scarce. One estimate puts extra annual revenue from Ms Ocasio-Cortez’s idea, which applies only to incomes above $10m, at perhaps $12bn, or 0.3% of the tax take. Ms Warren’s proposal would raise $210bn a year, her backers say—but they assume, implausibly, limited avoidance and no economic damage. Ultimately, the price of ambitious spending programmes will be tax increases that are also far-reaching. The crucial point about a strategy for taxing the rich is to realise that it has limits.
