Molecular monitoring of RNA regulation

The better we understand cellular processes such as RNA regulation, the better molecular therapies can be developed. Until now, it has been especially difficult to track the regulation of non-coding RNA, which is RNA that is not further converted into proteins.

The big idea: we need to reverse climate change, not just stop it

Taking carbon out of the atmosphere will become increasingly important, writes scientistThe past year has seen an unending drumbeat of climate-driven disasters. And yet, the climate story of this past decade has been one of slow but steady progress. Global CO2 emissions have flattened, and countries representing 88% of global emissions have adopted or announced plans to get to net zero in the...

Honey bee life spans are 50% shorter today than they were 50 years ago

A new study by University of Maryland entomologists shows that the lifespan for individual honey bees kept in a controlled, laboratory environment is 50% shorter than it was in the 1970s. When scientists modeled the effect of today's shorter lifespans, the results corresponded with the increased colony loss and reduced honey production trends seen by U.S. beekeepers in recent decades.

Starwatch: high-speed Leonids can be extremely bright and colourful

Dust grains forming meteor shower come from comet Tempel-Tuttle, which orbits sun every 33 yearsOne of the year’s major meteor showers takes place this week. The Leonids may not typically produce the most meteors but they can be very bright.The chart shows the view looking east-north-east from London at midnight as 17 November becomes 18 November. This is the night on which the shower is...
