While sea freight is recognised as a pathway for the movement of exotic organisms, there is little research that has quantified the risk. Soil collected from the external surfaces of sea freight was found to support live microorganisms, worms, seeds and insects, including various regulated biosecurity organisms. The research confirms that shipping containers provide a pathway for the movement of exotic species.

University and federal scientists used genetic sleuthing to study how salmon were affected by two major culvert replacements near the city of Bellingham. One project, a major upgrade under Interstate-5, had a big impact, while the other old culvert may have been less of a barrier to fish. Authors from the UW and NOAA are studying the use of environmental DNA, or eDNA, in future environmental impact reporting.

People who eat just two servings of red meat per week may have an increased risk of developing type 2 diabetes compared to people who eat fewer servings, and the risk increases with greater consumption, according to a new study. Researchers also found that replacing red meat with healthy plant-based protein sources, such as nuts and legumes, or modest amounts of dairy foods, was associated with reduced risk of type 2 diabetes.

Proteins are important molecules that perform a variety of functions essential to life. To function properly, many proteins must fold into specific structures. However, the way proteins fold into specific structures is still largely unknown. Researchers have developed a novel physical theory that can accurately predict how proteins fold. Their model can predict things previous models cannot. Improved knowledge of protein folding could offer huge benefits to medical research, as well as to various industrial processes.

Yeast cells are widely used to study G protein-coupled receptors (GPCRs), a large group of cell surface proteins in humans. However, several of these proteins lose their function when introduced into yeast cells. To tackle this issue, researchers developed an innovative strategy to restore GPCR function in yeast cells by inducing random mutations. Their findings can help understand GPCRs better and could pave the way to therapeutic breakthroughs for many diseases.

High-capacity and reliable rechargeable batteries are a critical component of many devices and even modes of transport. They play a key role in the shift to a greener world. A wide variety of elements are used in their production, including cobalt, the production of which contributes to some environmental, economic, and social issues. A team now presents a viable alternative to cobalt which in some ways can outperform state-of-the-art battery chemistry. It also survives a large number of recharge cycles, and the underlying theory can be applied to other problems.

Octopuses are fascinating animals -- and serve as important model organisms in neuroscience, cognition research and developmental biology. To gain a deeper understanding of their biology and evolutionary history, validated data on the composition of their genome is needed, which has been lacking until now. Scientists have now been able to close this gap and, in a new study, determined impressive figures: 2.8 billion base pairs -- organized in 30 chromosomes. What sounds so simple is the result of complex, computer-assisted genome analyses and comparisons with the genomes of other cephalopod species.

A new study finds that greenspace -- the vegetation in a neighborhood's yards, parks and public spaces -- has a positive impact on a key genetic marker associated with exposure to stress. However, the study also finds that the positive impact of greenspace isn't enough to compensate for other environmental challenges, such as air pollution.

Power grids -- the web of electrical networks that sprawl across countries and continents -- are under stress. Extreme weather events and volatile energy demands often push the system to the brink. Although these high-impact events can be very damaging, often overlooked is the impact of minor disruptions that trigger a domino effect throughout the system, according to a study analyzing European power blackouts. The findings showed that recovering power within 13 hours can reduce up to 52% of the power loss stemming from cascading events.

When stacked in five layers in a rhombohedral pattern, graphene takes on a rare 'multiferroic' state, exhibiting both unconventional magnetism and an exotic electronic behavior known as ferro-valleytricity.
