Cranes, sandpipers, ducks, geese and many other waterbirds have lost essential rest stops along their seasonal migration routes. Bird-friendly agriculture can assist in filling the gaps.
People love to hate them, but effective administrative systems shape good government. A political scientist weighs in on why reforming them is best done with care.
Carshares, bikeshares and the like are a positive for the environment, though access to them isn’t equal. What can be done to give everyone more transportation options?
Some scientists propose that in the beginning, geochemistry gave way to biochemistry — with no genetic material necessary. Only later did RNA and DNA appear.
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: 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.

How dangerous is it? Where did it come from? H5N1 influenza’s origins stretch back to the 1990s, and key events paved the way for the outbreak we’re seeing today.
A celebration of 2025 as the International Year of Quantum Mechanics and Science would be remiss without a look at how the carrier of electricity finally yielded its secrets — paving the way to the quantum era
With many collisions and much crumpling of rock, down the ages. The story holds lessons for how the edges of continents are built and change over time.
In metros like Reno, Nevada, citizen scientists hit the road to collect detailed temperature data — key to taming urban heat, saving lives and designing for a warmer future
Can genetically modified animals help ease the shortage of organs? After years of research into xenotransplantation, the field is at a turning point — yet risks and ethical issues remain.
UCLA’s Susan Perry has devoted decades to studying the fast-motion life of these New World primates and learning how the young acquire the skills they need to thrive
