A new study of molecular interactions central to the functioning of biological clocks explains how certain mutations can shorten clock timing, making some people extreme 'morning larks' because their internal clocks operate on a 20-hour cycle instead of being synchronized with the 24-hour cycle of day and night. Researchers found that the same molecular switch mechanism affected by these mutations
http://news.mit.edu/2020/passive-solar-powered-water-desalination-0207 – MIT claims they have broken the record (by more than twice). The system delivered pure water that exceeded city drinking water standards, at a rate of 5.78 liters per square meter (about 1.52 gallons per 11 square feet) of solar collecting area. This is more than two times as much as the record amount previously produced by
In an ever-more connected world, it would be easy to assume that loneliness was on its way out — after all, we now have unlimited opportunity to communicate with almost anyone we want at any time we please. But, in fact, it's still rife: according to the Campaign To End Loneliness , over nine million people in the UK describe themselves as "always or often lonely." Age has an impact here, too: an
For all the benefits in the expansion of the media landscape, we're still struggling with the spread of misinformation — and the damage is especially worrisome when it comes to information about science and health. Dan Gillmor, co-founder of the News Co/Lab at Arizona State University's Walter Cronkite School of Journalism and Mass Communication, will discuss his work on improving media literacy

This article is a collaboration between The Atlantic and the Pulitzer Center . The Amazon tends to evoke an Edenic vision—of a mysterious and impenetrable land, pregnant with beasts from jaguars to anacondas, rich with undiscovered flora. But parts of it are incongruous with this reputation, where big rig trucks rumble past dilapidated, grime-covered gas stations, and where land once thick with b
The United Nations (UN) launched the 2030 Agenda for Sustainable Development to address an ongoing crisis: human pressure leading to unprecedented environmental degradation, climatic change, social inequality, and other negative planet-wide consequences. This crisis stems from a dramatic increase in human appropriation of natural resources to keep pace with rapid…
When you can't quite put your finger on how you're feeling, don't worry — there may be a non-English word that can help you out. There are hundreds of words across the world for emotional states and concepts, from the Spanish word for the desire to eat simply for the taste ( gula ) to the Sanskrit for revelling in someone else's joy ( mudita ). But what about those words that exist across many la
Cereals from the Fertile Crescent and broomcorn millet from northern China spread across the ancient world, integrating into complex farming systems that used crop-rotation cycles enabled by the different ecological regions of origin. The resulting productivity allowed for demographic expansions and imperial formation in Europe and Asia. In this study, scientists illustrate that people moved these
The LIN28:pre-let-7:TUTase ternary complex regulates pluripotency and oncogenesis by controlling processing of the let-7 family of microRNAs. The complex oligouridylates the 3′ ends of pre-let-7 molecules, leading to their degradation via the DIS3L2 exonuclease. Previous studies suggest that components of this complex are potential therapeutic targets in malignancies that aberrantly…

I met Michael Avenatti exactly once, in the green room of MSNBC's Morning Joe in New York on March 16, 2018. That hour's guests were three: Avenatti, me, and the monstrously productive legal scholar Cass Sunstein, who had just edited a book on authoritarianism. Avenatti, not yet at the apogee of his fame, went first. He began the interview with officious and dramatic lawyer-speak ("I cannot say a
An artificial neural network can reveal patterns in huge amounts of gene expression data, and discover groups of disease-related genes. The scientists hope that the new method can eventually be applied within precision medicine and individualized treatment.
