Weather on Demand: Making It Rain Is Now a Global Business

Cloud seeding has been controversial since it was invented by Vincent Schaefer in 1946. A chemist for General Electric, Schaefer made the first snowstorm in a laboratory freezer. The media predicted that cloud seeding could perform miracles, from dousing forest fires to ensuring white Christmases. But doubts quickly arose about the impact of meddling with nature. Concerns that cloud seeding might “steal” water from an area a cloud is traveling toward—robbing Peter to water Paul, as it were—have been dispelled. Storm clouds continually regenerate and release only a portion of their moisture when they rain, which means you can’t “wring out” all the moisture from one cloud. “If anything, the area downwind would get more precipitation from cloud seeding, not less,” says Dave Reynolds, a meteorologist with the National Oceanic and Atmospheric Administration.
“There’s little dispute that if you can actually get the seeding material inside the clouds, it will enhance precipitation,” says Dan Breed, a scientist with the National Center for Atmospheric Research. “The question is, by how much?” Just as it’s hard to predict the weather, it’s hard to really know if you’ve made it rain or not. Breed’s own research—a nine-year, $14 million government-funded study he completed last year in collaboration with WMI and the University of Wyoming—found that seeding increased snowfall 5 percent to 15 percent from clouds in two Wyoming mountain ranges.

The fat city that declared war on obesity

Velveth is one beneficiary of a remarkable attempt to tackle obesity. For Oklahoma City has declared war on fat. First the mayor – realising he had become clinically obese just as his hometown was identified by a magazine as one of America’s most overweight cities – challenged his citizens to collectively lose a million pounds. But hitting that target was just the start: this veteran Republican politician then took on the car culture that shaped his nation and asked citizens to back a tax rise to fund a redesign of the state capital around people.
This unleashed an incredible range of initiatives, including the creation of parks, sidewalks, bike lanes and landscaped walking trails across the city. Every school is getting a gym. With the new emphasis on exercise, city officials spent $100 million creating the world’s finest rowing and kayaking centre in a Midwest town with no tradition of the sport beforehand. Overweight people are targeted at home and at work to alter their lifestyles, while data are used to discover the districts with the worst health outcomes so that resources can be poured in to change behaviour.
The experiment is unusual in terms of its ambition, breadth and cost, all of which take it beyond anything being attempted by other American cities in the fight against fat. The battle is being done with, rather than against, the fast food industry and soft drinks manufacturers, relying largely on persuasion instead of coercion through soda bans and sugar taxes. The city has been dubbed “a laboratory for healthy living”. Yet what makes the experiment quite so extraordinary is that it is being attempted in Oklahoma.

Scientists Propose a Research Agenda Aimed at Fostering Sustainable Human Progress

Since 2002, when The Times ran a special Science Times issue called “Managing Planet Earth,” I’ve been exploring how that might happen — or even if it’s possible. After all, I often find myself agreeing with what Cardinal Oscar Rodriguez Maradiaga, a close adviser to Pope Francis, said at the 2014 Vatican meeting on “sustainable humanity” that went on to underpin much of Francis’s encyclical: “Nowadays man finds himself to be a technical giant and an ethical child.”
One thing is clear. If societies are to improve their relationship with Earth’s vital systems in ways that work for the long haul, science has to be involved (including the sciences that reveal more about how humans perceive and respond to risks).
But that leads to questions. Science has helped demonstrate that we have entered the Anthropocene, an age in which humans, through our “great acceleration,” have become a planetary force and left a signature — in fallout, carbon, plastic and more — that could mark the dawn of a geological age of our own making (if not yet our own design).
But what does science do now?

As Heroin Use by Whites Soars, Parents Urge Gentler Drug War

The "War on Drugs" was a disaster, a policy failure, as well as a moral failure.

When the nation’s long-running war against drugs was defined by the crack epidemic and based in poor, predominantly black urban areas, the public response was defined by zero tolerance and stiff prison sentences. But today’s heroin crisis is different. While heroin use has climbed among all demographic groups, it has skyrocketed among whites; nearly 90 percent of those who tried heroin for the first time in the last decade were white.
And the growing army of families of those lost to heroin — many of them in the suburbs and small towns — are now using their influence, anger and grief to cushion the country’s approach to drugs, from altering the language around addiction to prodding government to treat it not as a crime, but as a disease.
“Because the demographic of people affected are more white, more middle class, these are parents who are empowered,” said Michael Botticelli, director of the White House Office of National Drug Control Policy, better known as the nation’s drug czar. “They know how to call a legislator, they know how to get angry with their insurance company, they know how to advocate. They have been so instrumental in changing the conversation.”

The FDA Just Approved One Cancer-Killing Virus. Expect More

By the numbers, the newest FDA-approved treatment for skin cancer doesn’t seem a real game changer. A $65,000 course of treatment extends melanoma patients’ lives by less than four and a half months, on average—and that result is barely statistically significant.
It’s how the new drug—Imlygic, made by the biotechnology company Amgen—works that has the oncology world so worked up. Imlygic is a virus—alive and infectious, the first to get a stamp of approval in the US for its ability to attack cancer cells. It opens a whole new front in the fight against cancer, which has the sneaky habit of coming back after chemotherapy, radiation, or surgery. “It is a totally new class of weapons that we can now use,” says Antonio Chiocca, a neurosurgeon at Brigham and Women’s Hospital. And the armory could be bigger, because coming up right behind Imlygic are over a dozen clinical trials for more anti-cancer viruses.
The idea of deploying viruses against cancer actually stretches back decades. The theory makes sense: When normal cells turn cancerous, replicating out of control, their virus-fighting machinery shuts down...

Nothing to See Here

A great tract of the Earth is on fire. It looks as you might imagine hell to be. The air has turned ochre: visibility in some cities has been reduced to 30 metres. Children are being prepared for evacuation in warships; already some have choked to death. Species are going up in smoke at an untold rate. It is almost certainly the greatest environmental disaster of the 21st Century – so far.
And the media? It’s talking about the dress the Duchess of Cambridge wore to the James Bond premiere, Donald Trump’s idiocy du jour and who got eliminated from the Halloween episode of Dancing with the Stars. The great debate of the week, dominating the news across much of the world? Sausages: are they really so bad for your health?
What I’m discussing is a barbeque on a different scale. Fire is raging across the 5000-kilometre length of Indonesia. It is surely, on any objective assessment, more important than anything else taking place today. And it shouldn’t require a columnist, writing in the middle of a newspaper, to say so. It should be on everyone’s front page.

Judge rules Kentucky man had the right to shoot down his neighbor’s drone

A Kentucky man who shot down a drone flying near his property has been cleared of all charges by a local judge. William Merideth was originally cited for criminal mischief and wanton endangerment after shooting the drone out of the air in July this year, but Judge Rebecca Ward ruled that he was right to do so after reviewing testimony from neighbors that the aircraft was flying near Merideth's house.
"I think it's credible testimony that his drone was hovering [...] for two or three times over these people's property, that it was an invasion of their privacy and that they had the right to shoot this drone," Ward told the court according to a report from Sky News. "I'm going to dismiss his charge."
