In its quest to feed, avoid nasty substances and just generally live its life, the brainless, one-celled Physarum polycephalum performs some impressive tricks of learning and memory
Researchers have long believed that a sudden, massive deluge filled a dry, salt-filled Mediterranean some 5 million years ago. Turns out that probably didn't happen, but there was still drama aplenty.
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.
In a year of funding chaos, ongoing climate change and pollution perils, we also saw the most powerful telescope yet, personalized gene therapy, and the next-best-thing to an HIV vaccine — not to mention a brand-new color
A push to move away from petroleum products — plus the perception that natural is gentler — has scientists lathering up new ingredients, from wood and fungus extracts to engineered proteins
