Identifying therapeutic drug targets using bidirectional effect genes
1hNature Communications, Published online: 13 April 2021; doi:10.1038/s41467-021-21843-8 Prioritising genes as potential drug targets is challenging and often unsuccessful once testing efficacy in humans. Here, the authors propose an approach to identifying drug targets that uses evidence from gain- or loss-of-function mutations associated with bidirectional effects on phenotypes.

19hA study of U.S. dietary trends over 16 years finds food consumed from typical sources, such as restaurants, grocery stores, schools, and work, is mostly of poor nutritional quality, with the exception of food from schools. Disparities in dietary quality by race, ethnicity, and income persist.
Artificial photosynthesis device gets better with use
19hResearchers have discovered why a water-splitting device made with cheap and abundant materials unexpectedly becomes more efficient during use. The finding could help make artificial photosynthesis a practical method for producing hydrogen fuel. "Our discovery is a real game-changer. I've never seen such stability." The new understanding of this mechanism could radically accelerate the commercial
Scientists need to become better communicators, but it's hard to measure whether training works
19hScience is essential to solving many of society's biggest problems, but it doesn't always find a receptive audience. Today, when curbing COVID-19 requires hundreds of millions of Americans to get vaccinated, it's more urgent than ever for scientists to be able to communicate effectively with the public.
Thawing permafrost cools Arctic currents: This might affect fish stocks
19hGEOGRAFI A new study by a University of Copenhagen researcher finds that thawing permafrost in Alaska causes colder water in smaller rivers and streams. This surprising consequence of climate change could affect the survival of fish species in the Arctic's offshore waters.
Dråben slider vingen: Hyperlokale vejrdata skal modvirke vindmølle-erosion
19hPLUS. Hvert år koster erosion af møllevinger vindindustrien flere milliarder kroner. Med hyperlokal vejrdata og to testmøller ud for Skotlands kyst forsøger forskere fra DTU at reducere problemet.
Blodet är fåglarnas värmeelement
19hFåglarnas blod producerar mer värme på vintern än på hösten då det inte är lika kallt. Den inre energiapparaten jobbar då för högtryck, men lägger kraften på att producera värme snarare än energi. Hemligheten finns i cellernas energifabrik, mitokondrierna. Däggdjur har inga mitokondrier i sina röda blodkroppar, något som fåglar har och som enligt forskarlaget från Lund och Glasgow gör att blodet
