Colossal undersea mountains, towering up to thousands of metres high, stir up deep sea currents: impacting how our ocean stores heat and carbon. An international team used numerical modelling to quantify how underwater turbulence around these mountains, called seamounts, influences ocean circulation; finding it is an important mechanism in ocean mixing and one that is missing from climate models used in policymaking.

Researchers have harnessed a bacterial immune defense system, known as CRISPR, to efficiently and precisely control the process of RNA splicing. The technology opens the door to new applications, including systematically interrogating the functions of parts of genes and correcting splicing deficiencies that underlie numerous diseases and disorders.

Archipelago case-study shows that removing invasive rats and restoring native vegetation could help bring back hundreds of thousands of breeding pairs of seabirds lost to tropical islands. Calculating that there are enough fish to sustain restored seabird populations should be an important consideration for restoration projects, scientists say. Restored seabird populations also provide huge boost to the health of surrounding coral reef ecosystems through restored nutrient cycles.

Researchers used theoretical calculations assessing electron orbital symmetry to synthesize new molecule designed to be both transparent and colorless while absorbing near-infrared light. This compound demonstrates the first systematic approach to producing such materials and have applications in advanced electronics. This compound also shows semiconducting properties.

Detecting marine debris from space is now a reality, according to a new study. Until now, the amount of litter -- mostly plastic -- on the sea surface was rarely high enough to generate a detectable signal from space. However, using supercomputers and advanced search algorithms, the research team has demonstrated that satellites are an effective tool for estimating the amount of litter in the sea.

A gold-coated milling vessel for ball mills proved to be a real marvel: without any solvents or environmentally harmful chemicals, the team was able to use it to convert alcohols into aldehydes. The catalytic reaction takes place at the gold surface and is mechanically driven. The vessel can be reused multiple times. 'This opens up new prospects for the use of gold in catalysis and shows how traditional materials can contribute to solving modern environmental problems in an innovative way,' says Borchardt.

An international research team has succeeded in developing a new type of material in the rather young research field of covalent organic frameworks. The new two-dimensional polymer is characterized by the fact that its properties can be controlled in a targeted and reversible manner. This has brought the researchers a step closer to the goal of realizing switchable quantum states.

A ubiquitous compound, called ester can be broken down to produce desirable alcohols and other chemicals for use across industries including pharmaceuticals and cosmetics, but the process can be costly, both financially and in terms of the environment. Researchers developed a novel photocatalyst 'N-BAP.' When irradiated with blue light, the photocatalyst reduces esters in the presence of oxalate, a negatively charged molecule found widely in nature, resulting in the desired alcohols.

Thirty-by-thirty: protect 30% of the planet by 2030. While conservation is popular in principle, the costs of actually enacting it often stall even the most earnest efforts. Researchers have now proposed a market-based approach to achieving the 30x30 targets in the ocean.

With their 'T-REX' method, researchers developed a glassy, amber-like polymer that can be used for long-term storage of DNA, such as entire human genomes or digital files such as photos.

The understanding of the global zinc cycle in our oceans has important implications in the context of warming oceans. A warmer climate increases erosion, leading to more dust in the atmosphere and consequently more dust being deposited into the oceans. More dust means more scavenging of zinc particles, leading to less zinc being available to sustain phytoplankton and other marine life, thereby diminishing the oceans' ability to absorb carbon.

When it comes to the ocean's response to global warming, we're not in entirely uncharted waters. A new study shows that episodes of extreme heat in Earth's past caused the exchange of waters from the surface to the deep ocean to decline.

In a feat aimed at understanding how cells move and creating new ways to shuttle drugs through the body, scientists say they have built a minimal synthetic cell that follows an external chemical cue and demonstrates a governing principle of biology called 'symmetry breaking.'
