How can we measure what makes a school system work?

Watch to find out where your country stacks up, and learn the single factor that makes some systems outperform others.

Kristie Ebi: How climate change could make our food less nutritious

Rising carbon levels in the atmosphere can make plants grow faster, but there's another hidden consequence: they rob plants of the nutrients and vitamins we need to survive. In a talk about global food security, epidemiologist Kristie Ebi explores the potentially massive health consequences of this growing nutrition crisis -- and explores the st...

Anees Bahji: How do steroids affect your muscles— and the rest of your body?

Steroids. They've caused global scandals. They're banned in most athletic competitions. Yet the same properties that help elite athletes and bodybuilders improve performance also make steroids valuable for treating many illnesses and injuries, such as AIDS and cancer. So if steroids are used as medicine, they must be safe to use recreationally, ...

In 2013, international migrants sent $413 billion home to families and friends — three times more than the total of global foreign aid (about $135 billion).

Robert Muggah: How to protect fast-growing cities from failing

Worldwide, violence is on the decline, but in the crowded cities of the global south — cities like Aleppo, Bamako and Caracas — violence is actually accelerating, fueled by the drug trade, mass unemployment and civil unrest.

Lord Nicholas Stern: The state of the climate — and what we might do about it

"War is ours...

Joel Selanikio: The big-data revolution in health care

Collecting global health data is an imperfect science: Workers tramp through villages to knock on doors and ask questions, write the answers on paper forms, then input the data -- and from this messy, gappy information, countries and NGOs need to make huge decisions. Data geek Joel Selanikio talks through the sea change in collecting health data...

Tina Arrowood: A circular economy for salt that keeps rivers clean

During the winter of 2018-2019, one million tons of salt were applied to icy roads in the state of Pennsylvania alone.

How can we better protect these precious natural resources? Physical organic...

Ramanan Laxminarayan: The coming crisis in antibiotics

Antibiotic drugs save lives. But we simply use them too much — and often for non-lifesaving purposes, like treating the flu and even raising cheaper chickens. The result, says researcher Ramanan Laxminarayan, is that the drugs will stop working for everyone, as the bacteria they target grow more and more resistant. He calls on all of us (patient...
