Published Replacing animal-based foods with alternative proteins would unlock land for carbon removal



Researchers report that replacing 50% of animal products with alternative proteins by 2050 could free up enough agricultural land to generate renewable energy equivalent in volume to today's coal-generated power while simultaneously removing substantial CO2 from the atmosphere.
Published New research uncovers biological drivers of heart disease risk



Over the past 15 years, researchers have identified hundreds of regions in the human genome associated with heart attack risk. However, researchers lack efficient ways to explore how these genetic variants are molecularly connected to cardiovascular disease, limiting efforts to develop therapeutics. To streamline analysis of hundreds of genetic variants associated with coronary artery disease (CAD), a team of researchers combined multiple sequencing and experimental techniques to map the relationship between known CAD variants and the biological pathways they impact.
Published Organic compound found in trees could prevent contact lens eye infections



Researchers say hydroquinine could be an effective naturally occurring disinfecting solution for contact lenses and help combat keratitis infections.
Published New study sheds new light on forests' role in climate and water cycle



Forests, which cover a third of Earth's land surface, are pivotal in carbon storage and the water cycle, though the full scope of their impact remains to be fully understood. In a new study, researchers provide new insights into the complex role forests play in the climate system and water cycle.
Published Nature is particularly beneficial for people on lower income



Data from a representative sample of the Austrian population suggests that the relationship between nature contact and well-being is consistently stronger for people on lower than higher incomes. However, this pattern was only found when people actively visited nature and not when they merely lived near greenspaces. Findings suggest the availability, accessibility and use of green and blue spaces can play an important role in reducing income-related health inequalities.
Published New approach for fast and cost-effective pathogen detection



The ability to detect diseases at an early stage or even predict their onset would be of tremendous benefit to doctors and patients alike. A research team now develops intelligent, miniaturized biosensor devices and systems using nanomaterials to determine biomolecules and cells as well as biochemical reactions or processes as disease markers. The team's current publication describes the development of a portable, palm-sized test system that can simultaneously carry out up to thirty-two analyses of one sample.
Published Warmer water may help rivers keep antimicrobial resistance at bay



New study suggests that temperature can influence the microbial competition in rivers.
Published Bacteria in the mouth linked to pulmonary fibrosis survival



Bacteria in the mouth may play a role in survival from idiopathic pulmonary fibrosis (IPF), finds a new study.
Published New approach to tackling bacterial infections identified



Researchers have identified a new approach to controlling bacterial infections. The team found a way to turn on a vital bacterial defense mechanism to fight and manage bacterial infections. The defense system, called cyclic oligonucleotide-based antiphage signaling system (CBASS), is a natural mechanism used by certain bacteria to protect themselves from viral attacks. Bacteria self-destruct as a means to prevent the spread of virus to other bacterial cells in the population.
Published Researchers discover key to molecular mystery of how plants respond to changing conditions



A team of researchers recently published a pioneering study that answers a central question in biology: how do organisms rally a wide range of cellular processes when they encounter a change -- either internally or in the external environment -- to thrive in good times or survive the bad times? The research, focused on plants, identifies the interactions between four compounds: pectin, receptor proteins FERONIA and LLG1 and the signal RALF peptide.
Published Complex tree canopies help forests recover from moderate-severity disturbances



Extreme events wipe out entire forests, dramatically eliminating complex ecosystems as well as local communities. Researchers have become quite familiar with such attention-grabbing events over the years. They know less, however, about the more common moderate-severity disturbances, such as relatively small fires, ice storms, and outbreaks of pests or pathogens.
Published Microfluidic environments alter microbe behaviors, opening potential for engineering social evolution



A research group explored how the social evolution of microbes can be manipulated by tuning the physical parameters of the environment in which they live.
Published Ancient Australian air-breathing fish from 380 million years ago



The rivers of Australia, which once flowed across its now dry interior, used to host a range of bizarre animals -- including a sleek predatory lobe-finned fish with large fangs and bony scales. The newly described fossil fish discovered in remote fossil fields west of Alice Springs has been named Harajicadectes zhumini by palaeontologists.
Published Mystery of novel clove-like off-flavor in orange juice solved



A research team has solved the mystery of a novel clove-like off-flavor in orange juice, the cause of which was previously unknown. The study proves for the first time that the undesirable flavor note is due to the odorant 5-vinylguaiacol. As the results of the study show, the substance is mainly produced during the pasteurization process when residues of a cleaning agent react with a natural orange juice component under the influence of heat.
Published Scientists develop new biocontainment method for industrial organisms



Researchers have developed a new biocontainment method for limiting the escape of genetically engineered organisms used in industrial processes.
Published Remarkable cellular architecture and phylogenetic position of the mysterious arm-swinging protist meteora sporadica



Researchers studied in detail the strange protist Meteora sporadica, which swings its two lateral arms back and forth. The results of the study indicated that M. sporadica has a complex cytoskeleton that is closely related to Hemimastigophora, a group of organisms considered to be one of the deepest branches of eukaryotes.
Published How plants obtain nitrogen by supplying iron to symbiotic bacteria



Researchers have discovered peptide factors that function in the shoot and root systems to transport iron into the root nodules colonized by nitrogen-fixing bacteria. Moreover, these peptide factors regulate nitrogen homeostasis by maintaining a balance between nitrogen and iron concentrations in plants without rhizobial symbiosis.
Published Apex predators not a quick fix for restoring ecosystems



An experiment spanning more than two decades has found that removal of apex predators from an ecosystem can create lasting changes that are not reversed after they return -- at least, not for a very long time. The study challenges the commonly held belief that the reintroduction of wolves to Yellowstone National Park restored an ecosystem degraded by their absence.
Published Flu virus variants resistant to new antiviral drug candidate lose pathogenicity



Influenza A viruses with induced resistance to a new candidate antiviral drug were found to be impaired in cell culture and weakened in animals, according to a new study.
Published Extra fingers and hearts: Pinpointing changes to our genetic instructions that disrupt development



Scientists can now predict which single-letter changes to the DNA within our genomes will alter genetic instructions and disrupt development, leading to changes such as the growth of extra digits and hearts. Such knowledge opens the door to predictions of which enhancer variants underlie disease in order to harness the full potential of our genomes for better human health.
