Mathematicians Have Solved Traffic Jams, And They’re Begging Cities To Listen
Traffic modeling is a complex branch of applied mathematics, partially because it assumes that drivers are selfish and pursuing their own goals, rather than any predictable or shared efforts.
Letting Slower Passengers Board Airplane First Really Is Faster, Study Finds
Commercial airlines often prioritize boarding for passengers traveling with small children, or for those who need extra assistance, before starting to board the faster passengers. It’s counter-intuitive, but it turns out that letting slower passengers board first actually results in a more efficient process.
Revealed: Air Pollution May Be Damaging ‘Every Organ In The Body’
Air pollution may be damaging every organ and virtually every cell in the human body, according to a comprehensive new global review. The research shows head-to-toe harm, from heart and lung disease to diabetes and dementia, and from liver problems and bladder cancer to brittle bones and damaged skin.
Exploring Detroit’s Largest Abandoned High School
This video explores one of the largest abandoned schools in Detroit, Cooley High School. At its peak, the school had over 3,400 students enrolled. At the center of the school is a beautiful auditorium with amazing architectural details, but unfortunately suffered a fire in 2017.
The Floating Utopia Of Salesforce Park
Salesforce Park, in downtown San Francisco, sits atop the Salesforce Transit Center. It is a lush, five-and-a-half-acre rooftop arcadia of rolling meadows and meticulously landscaped, climatically harmonious, drought-tolerant flora. San Francisco’s newest public space reflects Big Tech’s influence—and a city’s anxieties.
“AlphaGo”, Artificial Intelligence Taking On The Chinese Game Go
With more board configurations than there are atoms in the universe, the ancient Chinese game of Go has long been considered a grand challenge for artificial intelligence. On March 9, 2016, the worlds of Go and artificial intelligence collided in South Korea for an extraordinary best-of-five-game competition, coined The DeepMind Challenge Match.
Inside X, Google’s Top-Secret Moonshot Factory
Within Alphabet, Google’s parent company, it is grouped alongside Deepmind in “Other Bets”, although in that metaphor, X is more like the gambler. Its stated aim is to pursue what it calls “moonshots” – to try to solve humanity’s great problems by inventing radical new technologies.
There’s More Than One Way To Age. How Are You Doing It?
Most of us think we know what aging looks and feels like. It announces itself with wrinkled skin and gray, thinning hair. But scientists are cataloging far subtler signs of biological aging, evident long before hair is lost and skin starts to crinkle.
How Barcelona Is Taking City Streets Back From Cars
The city of Barcelona is testing out an urban design trick that can give cities back to pedestrians. It involves taking nine square city blocks and closing off the inside to through traffic. Buses, big freight trucks — or any vehicles that are trying to get from one part of town to the next — have to drive around the perimeter.
GauGAN: Changing Sketches Into Photorealistic Masterpieces In Seconds
A deep learning model developed by NVIDIA Research turns rough doodles into highly realistic scenes using generative adversarial networks (GANs). Dubbed GauGAN, the tool is like a smart paintbrush, converting segmentation maps into lifelike images.
The Global Drive To Reclaim Routes For Cyclists & Pedestrians
In many places, car-curbing efforts have begun to gain traction, driven in part by citizen activism. Cities like Paris have proclaimed car-free days. There are also plans to oust private vehicles from major metropolitan areas and there have even been proposals to create entirely new car-free cities from scratch.
A Landmark Study On The Origins of Alcoholism
By studying rats in a smarter way, scientists are finally learning something useful about why some drinkers become addicted and others don’t.
The Internet Is Destroying Our Collective Attention Span
The length of time our “collective attention” is on any given event has grown shorter, and topics become popular and then drop out of public view at an accelerating rate. It’s no surprise if it feels harder and harder to dwell deeply on any topic.
How We Can Cool Our Cities
With intensive development in urban areas and the impacts of global warming becoming ever more apparent, numerous cities around the world are now taking steps to reduce their temperatures and develop a more sustainable urban environment. Here are 3 innovative ways to bring temperatures down.
Why Bigger Planes Mean Cramped Quarters
The current Boeing 737s, the world’s most flown craft, are all longer than the original by up to 45 feet. And yet, on the inside, we’re getting squeezed. That’s because more space doesn’t equal more space in Airline World. It equals more seats—and typically less room per person.
Is The Second Farm Crisis Upon Us?
Farmers across the country are in a state of emergency with dairy and grain producers, new farmers, and farmers of color being hit the hardest. The term farm crisis is synonymous with the 1980s, when the bottom dropped out of the agricultural economy, sending thousands of farms into foreclosure and shuttering businesses.
When Her Best Friend Died, She Rebuilt Him Using Artificial Intelligence
It had been three months since Roman Mazurenko, Kuyda’s closest friend, had died. Kuyda had spent that time gathering up his old text messages, setting aside the ones that felt too personal, and feeding the rest into a neural network built by developers at her artificial intelligence startup.
The Food Deserts Of Memphis: Inside America’s Hunger Capital
In the ‘food deserts’ of Memphis, Tennessee, dominated by fast food outlets and convenience stores, locals lack what seems a basic human right in the richer half of the city: a supermarket. With a big gap in life expectancy, are these Americans doomed to die younger than their neighbours – or can they fight for their right to nutrition?
3D Printing Ink May Solve The “Toothpaste Problem”
A new kind of ink for 3D printing liquifies when pressed through the nozzle of a 3D printer, but then quickly returns to its original shape, researchers report. The invention paves the way for personalized biomaterial implants, according to new research. As things stand, however, personalized implants remain a long way off.
How Poor Americans Get Exploited By Their Landlords
It is a mistake to see slums as a byproduct of the modern city, rundown areas that occur by accident. Instead, researchers contend that the slum has long been a “prime moneymaker” for those who profit from land scarcity, racial segregation, and deferred maintenance.
What Does A Cashless Future Mean?
Operating in cash costs countries about 0.5% of their GDP every year. But cost isn’t the only incentive to move towards a cashless future. Many countries are going cashless at great speed. What are the advantages of ditching hard cash and what are the dangers?
