Published Plants transformed into detectors of dangerous chemicals



What if your house plant could tell you your water isn't safe? Scientists are closer to realizing this vision, having successfully engineered a plant to turn beet red in the presence of a banned, toxic pesticide.
Published Researchers develop DANGER analysis tool for the safer design of gene editing



A team of researchers has developed a software tool that provides a way for the safer design of genome editing in all organisms with a transcriptome. For about a decade, researchers have used the CRISPR technology for genome editing. However, there are some challenges in the use of CRISPR. The new analysis system overcomes these challenges and allows researchers to perform safer on- and off-target assessments without a reference genome. It holds the potential for applications in medicine, agriculture, and biological research.
Published Increased West Antarctic Ice Sheet melting 'unavoidable'



The West Antarctic Ice Sheet will continue to increase its rate of melting over the rest of the century, no matter how much we reduce fossil fuel use, according to new research. A substantial acceleration in ice melting likely cannot now be avoided, which implies that Antarctica's contribution to sea level rise could increase rapidly over the coming decades.
Published Soft, living materials made with algae glow under stress



Researchers have developed soft yet durable materials that glow in response to mechanical stress, such as compression, stretching or twisting. The materials derive their luminescence from single-celled algae known as dinoflagellates, which are embedded within the materials. The work was inspired by the bioluminescent waves caused by dinoflagellates during red tide events at San Diego's beaches.
Published Moving muscle fibers with magnets 'programs' how they align within tissue



Stimulating muscle fibers with magnets causes them to grow in the same direction, aligning muscle cells within tissue. The findings offer a simpler, less time-consuming way for medical researchers to program muscle cell alignment, which is strongly tied to healthy muscle function.
Published How cord-like aggregates of bacteria lead to tuberculosis infections



The ability of Mycobacterium tuberculosis (MTB), a serious respiratory infection, to form snake-like cords was first noted nearly 80 years ago. Investigators report the biophysical mechanisms by which these cords form and demonstrate how several generations of dividing bacteria hang together to create these structures that enable resistance to antibiotics.
Published Generating clean electricity with chicken feathers



Turning unused waste from food production into clean energy: Researchers are using chicken feathers to make fuel cells more cost-effective and sustainable.
Published Soil carried on sea freight loaded with dangerous pests and diseases, research finds



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.
Published Can golden retrievers live longer?



Researchers have found a gene associated with longevity in golden retrievers, one of the most popular breeds of dogs.
Published El Niño's changing patterns: Human influence on natural variability



Two recent scientific studies provide new insights into Earth's climate dynamics, with a particular focus on the El Niño phenomenon. The results show how El Niño responds to natural factors over extended periods, while highlighting the increasing role of human activities in shaping this climatic phenomenon in the modern era.
Published DNA shows where Washington culvert replacements helped spawning salmon



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.
Published Imprinted genes in the 'parenting hub' of the brain determine if mice are good parents



Whether a mouse is a good or bad parent can be traced back to imprinted genes in key neurons in the 'parenting hub' in the brain, according to a new study.
Published Scientists discover deepest known evidence of coral reef bleaching



Scientists have discovered the deepest known evidence of coral reef bleaching, more than 90 metres below the surface of the Indian Ocean. Identified during a research cruise, the damage to the deeper reefs in the Central Indian Ocean has been attributed to significant changes in the region's ocean temperature caused by the Indian Ocean Dipole. The researchers have also warned such incidences are only likely to increase as a result of present and future climate change.
Published Red meat consumption associated with increased type 2 diabetes risk



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.
Published Physical theory improves protein folding prediction



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.
Published Restoring the function of a human cell surface protein in yeast cells



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.
Published Stolen genes allow parasitic control of behavior



A research team has discovered that parasites manipulate their hosts using stolen genes that they likely acquired through a phenomenon called horizontal gene transfer.
Published Soft optical fibers block pain while moving and stretching with the body



New soft, implantable fibers can deliver light to major nerves through the body. They are an experimental tool for scientists to explore the causes and potential treatments for peripheral nerve disorders in animal models.
Published Yeast speeds discovery of medicinal compounds in plants



Researchers have harnessed the power of baker's yeast to create a cost-effective and highly efficient approach for unraveling how plants synthesize medicinal compounds, and used the new method to identify key enzymes in a kratom tree.
Published Study elucidates evolution of mosquitoes and their hosts



Study creates a mosquito family tree to better understand disease transmission and host choice.
