Published Not so simple: Mosses and ferns offer new hope for crop protection



Mosses, liverworts, ferns and algae may offer an exciting new research frontier in the global challenge of protecting crops from the threat of disease.
Published The detection of a massive harmful algal bloom in the Arctic prompts real-time advisories to western Alaskan communities



A summer 2022 research cruise that detected a massive and highly toxic harmful algal bloom (HAB) in the Bering Strait has provided a dramatic example of science that utilized new technology to track a neurotoxic HAB and effectively communicate that information in real-time to protect remote communities in coastal Alaska.
Published Phage-derived enzyme targets E. faecalis biofilms to mitigate acute graft-versus-host disease



Acute graft-versus-host disease occurs when donor immune cells attack the recipient's tissues after an allogeneic hematopoietic stem cell transplantation (allo-HCT). Researchers recently identified a bacteriophage-derived enzyme called endolysin capable of targeting biofilms formed by Enterococcus faecalis. Their findings offer hope for tailored interventions in allo-HCT.
Published Big gain in battle against harmful bacteria



An unexpected find has enabled important progress to be made in the battle against harmful bacteria.
Published Tackling the challenge of coca plant ID: Wild vs cultivated for cocaine



A new paper reveals that it's not as straightforward as it might seem. Despite decades of data collection by the United Nations Office on Drugs and Crime (UNODC), which has been valuable to monitor changes in areas occupied by illegal coca plantations in South America, there is no reliable scientific method to distinguish between different types of coca plants.
Published Researchers show promising material for solar energy gets its curious boost from entropy



Researchers discovered a microscopic mechanism that solves in part the outstanding performance achieved by a new class of organic semiconductors known as non-fullerene acceptors (NFAs).
Published Study examines tree adaptability to climate change



Many trees could expand their ranges by more than 25 percent based on their potential temperature tolerances.
Published New one-step method to make multiple edits to a cell's genome



A team of scientists have developed a new method that enables them to make precise edits in multiple locations within a cell -- all at once. Using molecules called retrons, they created a tool that can efficiently modify DNA in bacteria, yeast, and human cells.
Published Global database reveals large gaps in our knowledge of four-footed animals



Researchers developed TetrapodTraits -- a global database of animals with four feet -- which can now be applied for better ecology, evolution and conservation research.
Published How a plant app helps identify the consequences of climate change



A research team has developed an algorithm that analyses observational data from a plant identification app. The novel approach can be used to derive ecological patterns that could provide valuable information about the effects of climate change on plants.
Published Mining rare earth metals from electronic waste



A small molecule that naturally serves as a binding site for metals in enzymes also proves useful for separating certain rare earth metals from each other. In a proof of concept, the process extracts europium directly from fluorescent powder in used energy-saving lamps in much higher quantities than existing methods. The researchers are now working on expanding their approach to other rare earth metals. They are in the process of founding a start-up to put the recycling of these raw materials into practice.
Published Ancient large kangaroo moved mainly on four legs, according to new research



A type of extinct kangaroo that lived during the Pleistocene around two and a half million to ten thousand years ago, known as the 'giant wallaby', was a poor hopper, a study has found.
Published Study projects major changes in North Atlantic and Arctic marine ecosystems due to climate change



New research predicts significant shifts in marine fish communities in the North Atlantic and Arctic Oceans as a result of climate warming.
Published Raw milk is risky, but airborne transmission of H5N1 from cow's milk is inefficient in mammals



While H5N1 avian influenza virus taken from infected cow's milk makes mice and ferrets sick when dripped into their noses, airborne transmission of the virus between ferrets -- a common model for human transmission -- appears to be limited. These and other new findings about the strain of H5N1 circulating among North American dairy cattle this year come from a set of laboratory experiments. Together, they suggest that exposure to raw milk infected with the currently circulating virus poses a real risk of infecting humans, but that the virus may not spread very far or quickly to others.
Published Scientists discover how to improve vaccine responses to potentially deadly bacterium



Researchers have taken a leap forward in understanding how we might fight back against the potentially deadly MRSA bacterium. They have shown in an animal model that targeting a key suppressive immune molecule (IL-10) during the delivery of a vaccine improves the ability of the vaccine to protect against infection.
Published Study reveals environmental impact of artificial sweeteners



A recently published study demonstrates how sucralose affects the behavior of cyanobacteria -- an aquatic photosynthetic bacteria -- and diatoms, microscopic algae that account for more than 30% of the primary food production in the marine food chain.
Published Ancient dingo DNA shows modern dingoes share little ancestry with modern dog breeds



A study of ancient dingo DNA revealed that the distribution of modern dingoes across Australia, including those on K'gari (formerly Fraser Island), pre-dates European colonization and interventions like the dingo-proof fence.
Published Coral reefs: Battlegrounds for survival in a changing climate



Coral reefs, those vibrant underwater cities, stand on the precipice of collapse. While rising ocean temperatures and coral bleaching grab headlines, a new essay reveals a hidden layer of complexity in this fight for survival: the often-overlooked roles of the reefs' smallest inhabitants.
Published New extremely fast carbon storage technology



A new way to store carbon captured from the atmosphere works much faster than current methods without the harmful chemical accelerants they require.
Published New bio-based tool quickly detects concerning coronavirus variants



Researchers have developed a bioelectric device that can detect and classify new variants of coronavirus to identify those that are most harmful. It has the potential to do the same with other viruses, as well.
