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 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 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 You say genome editing, I say natural mutation



A plant geneticist and computational biologist teamed up to decipher the unpredictability of natural and engineered mutations in tomatoes. They discovered some combinations of mutations behave as expected while others are more erratic. Their work may help scientists find some order in the chaos of evolution and genome editing.
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 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 California supervolcano is cooling off but may still cause quakes



New high-resolution images of the Long Valley Caldera indicate that the subsurface environment is cooling off, releasing gas and fluids that contribute to seismic activity.
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 Scientists uncover new way viruses fight back against bacteria



A microscopic discovery will not only enable scientists to understand the microbial world around us but could also provide a new way to control CRISPR-Cas biotechnologies.
Published New insights into the genetics of the common octopus: Genome at the chromosome level decoded



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.
Published Greener neighborhoods can protect us -- at the cellular level



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.
Published Unlocking the secrets of cell behavior on soft substrates: A paradigm shift in mechanobiology



A research group has developed a new method for studying how cancer cells function in softer and stiffer tissue environments. This insight challenges the existing paradigm, opening up new possibilities for research in cancer biology and tissue engineering.
Published Whaling wiped out far more fin whales than previously thought



Whaling in the 20th century destroyed 99% of the Eastern North Pacific fin whale breeding population. Because there is enough genetic diversity, current conservation measures should help the population rebound without becoming inbred. The future of fin whales in the Gulf of California depends on the recovery of the Eastern North Pacific population.
Published Researchers test seafloor fiber optic cable as an earthquake early warning system



One of the biggest challenges for earthquake early warning systems (EEW) is the lack of seismic stations located offshore of heavily populated coastlines, where some of the world's most seismically active regions are located. In a new study, researchers show how unused telecommunications fiber optic cable can be transformed for offshore EEW.
Published Critical step made for managing brushtail possums



Researchers say mapping the genetic code of the brushtail possum will benefit those working to both conserve and control the animal.
Published Unlocking secrets of immune system proteins: A potential path to new treatments



Using cryo-electron microscopy (cryo-EM), researchers captured unprecedented images of key immune system receptors interacting with messenger proteins, elucidating how the receptors change shape upon activation and transmit signals within the cell. The findings suggest new pathways for developing therapeutic molecules for diseases such as COVID-19, rheumatoid arthritis, neurodegenerative diseases and cancer.
Published Boosting weak immune system: Scientists find an unusual weapon against virus



Infections with cytomegalovirus (CMV) are extremely common and often pose no major threat to the vast majority of people. They can however be deadly for people whose immune system is weakened, e.g., after bone marrow transplantation. Current treatments against CMV infections are very limited and can have severe side effects. Researchers now propose a new way to protect against CMV. Instead of targeting the virus, their approach boosts the weak immune system and lets it fight the virus on its own.
