Biologists discover a new type of control over RNA splicing

RNA splicing is a cellular process that is critical for gene expression. After genes are copied from DNA into messenger RNA, portions of the RNA that don't code for proteins, called introns, are cut out and the coding portions ...

10 new sponge species discovered in Hawaii's Kāne'ohe Bay

In a succession of studies published this week and last month in the journals PeerJ and Zootaxa, researchers at Hawai'i Institute of Marine Biology (HIMB) Toonen-Bowen (ToBo) Lab, using a technique that explores both genes ...

Sulfur may be a new tool for finding alien life

Astronomers have identified sulfur as a potentially crucial indicator in narrowing the search for life on other planets. While sulfur itself is not necessarily an indication of habitability, significant concentrations of ...

Alaska's lakes and ponds reveal effects of permafrost thaw

As climate change warms the Arctic, permafrost is thawing, and carbon trapped within the soil is moving into the atmosphere. Permafrost stores twice as much carbon as the atmosphere, but the degree to which this frozen carbon ...

Rare trio of weak bosons observed at Large Hadron Collider

As the carriers of the weak force, the W and Z bosons are central to the Standard Model of particle physics. Though discovered four decades ago, the W and Z bosons continue to provide physicists with new avenues for exploration.

AI tool creates 3D video game worlds with iterative design

A generative artificial intelligence (AI) tool that could help video game designers to craft gameplay iteratively is presented in a Nature paper. The AI model, developed by researchers at Microsoft, generated robust three-dimensional ...

What is quantum coherence?

We say a message is incoherent when we can't make it out, or when it doesn't make sense. A scribbled note, a drunken argument or a conversation taking place five tables down in a crowded cafe might all be incoherent. In general, ...

Storing CO₂ underground in Switzerland

To achieve its net zero climate target by 2050, Switzerland must press forward with the energy transition—whether in electricity, heating or mobility. The permanent storage of CO2 is another important challenge. In particular, ...

Devastating storms define Appalachia's 2024 climate

After a year of weather extremes that brought everything from deadly floods to bitter cold, experts at East Tennessee State University have released a detailed analysis of the region's 2024 weather patterns.

The beauty standard is intensifying. At what cost?

The internet is abuzz with talk of beauty and the lengths we'll go to achieve it. From Lindsay Lohan's recent transformation to Donatella Versace's "new look", those of us plugged in online can't help but gab over the rise ...
