VIDEO: Knowable Magazine’s interviews with experts during the pandemic revealed many missed opportunities and blunders in the US response to Covid-19, which was marked by excess American deaths and disability. The experience does offer lessons on how to better prepare for what scientists call the inevitable emergence of the next global health emergency.
VIDEO: Tens of millions of people are living with long Covid. Yale immunologist Akiko Iwasaki explains the current state of play in the search for causes of, and treatments for, this potentially debilitating illness.
VIDEO: Even a mild SARS-CoV-2 infection can cause inflammation that disrupts neural communication, says Stanford neurologist Michelle Monje. Her concern is that Covid-19 may leave millions dealing with cognitive problems, from a loss of mental sharpness to lapses in memory, that prevent them from returning to their previous level of function.
VIDEO: Where do new diseases come from? As people increasingly push into remote areas, the risk of encountering new pathogens increases, says wildlife epidemiologist Jonna Mazet.
VIDEO: In August 2020, the Dome Fire burned more than 40,000 acres of the iconic species’ range in the Mojave Desert, leaving a graveyard of blackened trees. A massive replanting effort now underway hopes to return life to the fragile ecosystem by boosting numbers of the climate-threatened plant.
VIDEO: Delays, errors and a fragmented response initially kept public health officials in the dark about the spread of SARS-CoV-2. More tests and easy access could still play a critical role in slowing the virus.
VIDEO: New York Times science reporter Apoorva Mandavilli chronicles the rise of the delta variant, the latest of many twists in the pandemic that she’s covered since it began. Delta has left parents in an especially tough spot, with schools opening but young children still vulnerable.
VIDEO: The pandemic has highlighted the complex links between inequality, racism and disease risk in America. Harvard public health scholar David Williams explains.
VIDEO: Scientists expected the novel coronavirus would mutate and change. But its runaway spread means new, more dangerous variants are more likely to emerge. Harvard computational geneticist Pardis Sabeti explains.
VIDEO: Covid-19 may be a public health crisis, but has had real impacts on the economy. MIT’s Andrew Lo discusses what’s happened and why history suggests a financial boom may be in the future.
VIDEO: One year into the pandemic, a clearer understanding of how Covid-19 infections spread suggest people need to shift efforts away from cleaning surfaces and toward better ventilation and filtration
VIDEO: Diverting recoverable materials helps keep trash from overwhelming landfills, but the industry still faces many challenges. Consumer education, innovative technologies and turning wastes to energy can help manage the rubbish problem.
VIDEO: Many cellular processes are guided by fluctuations of molecules, from circadian clocks to the feat of precisely dividing into two daughter cells
VIDEO: Doctored images, fake videos and computer-generated news are easier than ever to create and distribute. Here’s why you should worry and what you can do.
VIDEO: Scientists have captured live video of parts of the most fundamental event in biology — cells reading and copying DNA instructions to make proteins
VIDEO: Megafires, which burn over 100,000 acres, can cause catastrophic damage. Researchers are studying fire behavior in the lab and in the field in order to fight these flames more effectively.
VIDEO: The humble bivalves can clean polluted water and bump up diversity — but there's plenty more to learn about the odd group of mollusks that make their homes in our streams and rivers
