What legacy lies ahead for Black Lives Matter?

Historically, the road to reform has often begun with protesters taking to the streets. A sociologist and a political scientist take stock of whether today’s activism will lead to actual change.

In the months since widespread protests erupted around the United States after the killing of George Floyd, some things have already changed. Police officers involved in the Minneapolis man’s death were charged in the murder case. Many police agencies have moved to ban or restrict the kind of neck hold used on Floyd. Statues of Confederate soldiers and others associated with racist pasts have been toppled or removed in many cities.

A raft of police reform policy measures have been proposed in most states, and activists have pushed city councils to reduce police departments’ budgets and shift resources toward other programs. The protesters, led by Black Lives Matter (BLM) and other national and local groups in reaction to Floyd’s death and those of other Black Americans, have achieved some initial reforms and successes.

Will there be deeper, lasting change? The BLM protests have seen tens of millions of Americans taking to the streets to protest the deaths, dwarfing the size of earlier waves of protest in the US. Americans’ support for BLM grew by at least 24 percent immediately after Floyd’s death in May, according to a June survey by the Pew Research Center…

As Risks of Space Wars Grow, Policies to Curb Them Lag

A pair of recent reports point to growing space threats, but efforts to prevent conflicts are stagnant or out of step.

On April 22, Iran’s Islamic Revolutionary Guard Corps announced a successful launch of what they described as a military reconnaissance satellite, which came after several failed attempts. The satellite joined a growing list of weapons and military systems in orbit, including Russia’s test of a missile system designed to destroy satellites, also in April, and India’s test of an anti-satellite weapon, which the country launched in March 2019.

Experts like Brian Weeden, director of program planning at the Secure World Foundation (SWF), a nonpartisan think tank based in Broomfield, Colorado, worry that these developments — all confirmed by the newly reestablished United States Space Command — threaten to lift earthly conflicts to new heights and put all space activities, peaceful and military alike, at risk. Researchers at SWF and the Center for Strategic and International Studies (CSIS), a nonpartisan think tank in Washington, D.C., both released reports this year on this rapidly evolving state of affairs. The reports suggest that the biggest players in space have advanced their space military abilities, including anti-satellite weapons, which destroy satellites, and technologies that merely disrupt spacecraft, for instance by blocking data collection or transmission.

Many of these technologies, if deployed, could ratchet up an arms race and even spark a war in space, the SWF and CSIS researchers caution. Just blowing up a single satellite scatters debris throughout the atmosphere, said Weeden, co-editor of the SWF report. Such an explosion could hurl projectiles in the paths of other spacecraft and threaten the accessibility of space for everyone…

After Hiroshima, nuclear threats still have a long half-life

The massive explosion that rocked Beirut’s port likely killed hundreds, wounded thousands, and rendered 300,000 Lebanese people homeless. But in comparison, the atomic bomb dropped by the United States’s B-29 bombers on Hiroshima and Nagasaki 75 years ago had 15 times that explosion’s destructive power, killed hundreds of thousands of Japanese people, and sickened many more.

After three quarters of a century, the threat of mutually assured destruction engulfing our planet continues to loom over us. President Trump’s nuclear policies — including tearing up international treaties, deploying so-called “low-yield” warheads on submarines, keeping nukes on “hair-trigger alert” to be launched at a moment’s notice, and refusing to rule out new nuclear testing — have only expanded those threats and encouraged proliferation. Trump’s successor will have a huge responsibility to pull us back from the brink and disperse the calamitous mushroom cloud from our horizon.

While the Hiroshima bomb erupted with the energy of 15,000 tons of TNT, many weapons available for launch in the US’s and other country’s arsenals have the explosive power of megatons of TNT. Even the low-yield nukes promoted by the Trump administration aren’t particularly small, and they arguably encourage an arms race and lower the bar toward somebody once again pressing the big red button and unleashing a weapon of mass destruction. Combined with the lack of US support for at least four nuclear treaties, it’s no wonder that leaders of North Korea, Iran, Saudia Arabia, and Turkey want such weapons for themselves.

As Lesley M. M. Blume writes in her new book, Fallout, if it weren’t for journalist John Hersey’s reporting on the horrific devastation and death toll in Hiroshima, Americans might not be aware of the damage the world’s worst weapons have wrought. Another new book, The Beginning or The End, by Greg Mitchell, also demonstrates the attempt by the federal government and Hollywood to cover up the massive death and destruction let loose by the atom bomb. After the war, such an indisputable attack on civilians and civilian infrastructure came to be viewed as a war crime and a crime against humanity.

With the pandemic and climate change, we already have plenty of threats to humanity. 75 years is already too much time to have such horrific weapons in our midst. Trump’s successor will have their work cut out for them to ensure that our era of toying with nuclear disaster soon comes to an end.

Does dark matter exist?

Dark matter is the most ubiquitous thing physicists have never found: it’s time to consider alternative explanations.

In 1969, the American astronomer Vera Rubin puzzled over her observations of the sprawling Andromeda Galaxy, the Milky Way’s biggest neighbour. As she mapped out the rotating spiral arms of the stars through spectra that she and colleagues had carefully measured at the Kitt Peak National Observatory and the Lowell Observatory, both in Arizona, she noticed something strange: the stars in the galaxy’s outskirts seemed to be orbiting far too fast. So fast that she’d expect them to escape Andromeda and fling out into the heavens beyond. Yet the whirling stars stayed in place.

Rubin’s research, which she expanded to dozens of other spiral galaxies, led to a dramatic dilemma: either there was much more matter out there, dark and hidden from sight but holding the galaxies together with its gravitational pull, or gravity somehow works very differently on the vast scale of a galaxy than scientists previously thought…

Over the past half century, no one has ever directly detected a single particle of dark matter. Over and over again, dark matter has resisted being pinned down, like a fleeting shadow in the woods. Every time physicists have searched for dark matter particles with powerful and sensitive experiments in abandoned mines and in Antarctica, and whenever they’ve tried to produce them in particle accelerators, they’ve come back empty-handed. For a while, physicists hoped to find a theoretical type of matter called weakly interacting massive particles (WIMPs), but searches for them have repeatedly turned up nothing.

With the WIMP candidacy all but dead, dark matter is apparently the most ubiquitous thing physicists have never found. And as long as it’s not found, it’s still possible that there is no dark matter at all. An alternative remains: instead of huge amounts of hidden matter, some mysterious aspect of gravity could be warping the cosmos instead…

The complexities of a universal basic income

It’s a hot topic under political debate: providing cash grants as a social safety net. Small programs hint at how it might work — or not — on a national scale.

“Universal basic income” was for a long time an obscure term bandied about in economics circles. That’s no longer the case. The idea, usually involving a monthly cash grant to every person with no strings attached, has entered mainstream discourse.

Former US presidential candidate Andrew Yang made it a main plank of his campaign. Occupy Wall Street activists called for it in their social movement. Some economists and policymakers — amid concerns about job insecurity in an age of rapid automation and the widening income gap between rich and poor — are seeking big solutions. And the idea has reemerged with the current Covid-19 pandemic that has wiped out the income of many workers practically overnight.

Many political leaders support at least expanding current income-assistance programs — a much-talked-about idea in the lead-up to the recent Democratic presidential primaries. These existing programs focus on specific groups: people who are underemployed, disadvantaged or have a low income, including those who are elderly, disabled or have children. But a universal basic income would go further. It would remove all conditions on the payments, giving a measure of security without the stigma sometimes associated with current programs…

How to optimize your headspace on a mission to Mars

Imagine being confined to a metal cell with a couple of other people and few amenities for months or even years. Maybe after that, you’ll be moved to a new compound, but you still have no privacy and extremely limited communication with your family and anyone else in the outside world. You feel both crowded and lonely at the same time, and yet no one comes to treat your emerging mental-health problems.

While this might sound like life in prison, it could just as easily be life as a deep-space explorer, in a sardine can of a rocket hurtling to Mars or a more distant world. Despite years of research by NASA and others, scientists have little insight into the psychological, neurological and sociological problems that will inevitably afflict space travellers battling depression, loneliness, anxiety, stress and personality clashes many millions of miles away from home. Sure, a growing body of research now documents the impact of microgravity on one’s brain and body, along with the exercises and medical attention needed to mitigate the effects. But social isolation, limited privacy, interpersonal issues, along with vast separation from loved ones, remain relatively unexplored.

Even massive Star Trek spaceships – with plenty of space per person – come with counsellors on board, but what if the crew member with counselling training gets injured or falls ill during a critical moment? If morale plummets and rapport among the team disappears, an emergency situation could spell the end of both the astronauts and the mission…

Iran Could’ve Been Our Ally

As an Iranian-American writer, I just wanted to offer a few brief thoughts on the current simmering conflict, which is threatening to boil over…

Despite claims of a clash of cultures or civilizations, Iran and the United States actually have some common interests in the Middle East. And had history played out differently, the countries might even have become allies, while Iranians and Americans could have been colleagues especially in the arts and sciences. But to forge a new relationship, at least one of mutual respect, it will require coming to terms with America’s oppressive past in the region.

Azadi Tower, Tehran

Britain was once Iran’s biggest nemesis, but the US government took on that mantle in 1953. That was when the CIA played a major role in overthrowing Mohammad Mossadegh, Iran’s popular elected leader who had the gall to nationalize the oil company later known as BP, which had for decades been extracting Iranian oil to grease the wheels of the British Empire.

US officials re-installed the Shah, a brutally repressive autocrat who was so disliked that Iranians united to overthrow him. Students, activists, trade unionists, poets, and Islamists came together in that revolution, but the latter shunned the others and assumed power when the dust settled. US governments since then have failed to understand Iranians’ anger against them. The US supported Iraq in the Iran-Iraq war, shot down a civilian airplane that killed 290 people, invaded Iran’s two biggest neighbors with more than 100,000 troops, supported Iran’s two biggest rivals with powerful weaponry, installed dozens of military bases that surround the country, insisted Iran’s part of some Axis of Evil, and repeatedly hit Iranians with sanctions, to which they have no recourse. No wonder Iranians feel threatened.

Iran remains a divided country: many Iranians support their government in response to the Trump administration’s crippling economic sanctions and assassination of General Soleimani while others oppose their government’s mishandling of the economy and limitations on their political freedoms. (Some Iranians are in both camps.)

“That’s history” is a dismissive phrase in America, but to Iranians, a proud people whose trials and achievements go back millennia, history matters indeed.

I’ve visited many places throughout Iran to give talks and to see family. Iranians have their own critically acclaimed and Oscar-winning films, but they love American movies, too. They quote their own poets and writers, but they also read American literature. They have plenty of physicists, astronomers and doctors — algebra, optics and pediatrics all arguably began in Persia — and these accomplished scientists would jump at the opportunity to collaborate with their American counterparts.

Relations between the two nations seem to be at their nadir, but both Americans and Iranians don’t want war. If the Trump administration and leading Democrats realize that the days of US empire in the Middle East are over, they can step back from the brink of war, withdraw troops and military bases, and stake out a path toward peace, which would greatly benefit the people of both countries.

Searching for Meaning on Our Pale Blue Dot

In “For Small Creatures Such as We,” Sasha Sagan reflects on her upbringing and the power of secular faith.

Religion, and Christianity in particular, appear to be becoming less important among younger Americans, declining dramatically in the past two decades, according to a recent Wall Street Journal poll. So where can people turn to share a common culture and community?

For Sasha Sagan, the author of “For Small Creatures Such as We,” even a dinner party tradition or a shared song can generate the camaraderie people may be missing. Aimed primarily at atheist and agnostic readers, her book is both a memoir of growing up as the daughter of astronomer Carl Sagan and writer Ann Druyan in Ithaca, New York, where her father was a professor at Cornell University, as well as an exploration of connections and universal themes among religions, cultures, and secular communities around the world.

Her parents wrote and produced many acclaimed and popular science books and TV programs, including “Cosmos,’’ “Contact,” “Pale Blue Dot,’’ and “The Demon-Haunted World.’’ The movie version of “Contact,’’ which came only seven months after Sagan’s death in 1996, included the line that inspired his daughter’s title: “For small creatures such as we, the vastness is bearable only through love.”

Like her parents, Sagan has plenty of gifts as a writer and communicator. It’s her livelihood, in fact: She’s not a scientist but a TV producer, filmmaker, writer, editor, and speaker. In her book, she writes of the “immense brazen beauty of life” and argues that “from the genetic information in our blood to the movement of the Earth around the sun, our vast universe provides us with enough profound and beautiful truths to live a spiritually fulfilling life.”

Robot Truckers Are Here — They Just Happen to Be Human

Electronic tracking devices and other surveillance tech monitor just about everything human drivers do, automating what was once an independent job.

Truckers drink coffee and complain about Mondays just like everybody else. Work can be a slog. But unlike what you’re probably used to in your office, many truck drivers now deal with rigorous and near-constant electronic surveillance — a camera pointed at them to closely monitor productivity, for example.

“You feel like you’re being watched all the time,” says John Grosvenor, founder of Truckers United for Freedom, a group that advocates for truckers’ rights. “Some people act out in inappropriate behaviors at times — they stick their finger in their nose or do something crass—as a form of rebellion. All in all, they hate it.”

Devices now track every aspect of a trucker’s job, including their current location, where they’re going, how fast they’re driving, and when they take a break and how long it lasts. Mostly for insurance purposes in the event of an accident, trucks often come equipped with cameras trained on both the driver and the road. They also have a variety of radar, lidar, and ultrasound sensors, as well as accelerometers and gyroscopes. The data feeds into an onboard computer, similar to self-driving vehicles. One firm has even developed a steering wheel with built-in heart monitors to monitor fatigue.

Since companies need truckers to deliver specific things at specific times, truckers don’t have regular routes like other drivers, but instead might be hauling paper towels to New York one day and motoring a haul of bolts down to Pittsburgh the next. Any delay can foul up assembly lines and supply chains. “That’s really the foundation of the day-to-day, routine monitoring of truck drivers since the mid-1990s,” says Steve Viscelli, a sociologist at the University of Pennsylvania and author of The Big Rig: Trucking and the Decline of the American Dream. “[Trucking] has slowly evolved to look very much like the algorithmic management that everyone thinks is new about platforms like Uber.”

Apocalypse How-To? Better Science Fiction Stories About Threats to Humanity

While plenty of apocalypses occur in science fiction, the risks could be shown more realistically, experts argue.

Which science fiction movies, TV shows, and comic books give a realistic portrayal of the consequences of “antibiotic resistance”? None, said Jessica Petrillo, a State Department senior health security officer. There’s a dearth of stories exploring how overusing antibiotics is fueling drug-resistant diseases that kill more and more people every year, she said. Her first goal is to try to raise awareness of the global problem, including through “comic book diplomacy.”

That’s an extreme case, but a panel of government agents and scientists at San Diego’s Comic-Con last Friday argued that science fiction writers and artists can craft better stories about disasters that could imperil civilization. The possibility of a coming apocalypse pervades science fiction today, but how likely are those possibilities in the next few decades or the next century? These experts tried to figure out how nuclear proliferation, killer asteroids and pandemics might actually arise.

Take nuclear terrorism. Many movies and TV programs, including “24,” make it appear almost easy to acquire or engineer nuclear devices. But countries typically hold such devices with the highest security measures, such that maybe only a terrorist organization with the capabilities of SPECTRE from the James Bond movies or The Syndicate in the DC Comics universe could get around them, said Gregory Bernard, a Department of Homeland Security officer…
