Published 'Teacher Toads' can save native animals from toxic cane toads



Scientists from Macquarie University have come up with an innovative way to stop cane toads killing native wildlife by training goannas to avoid eating the deadly amphibians.
Published Machine learning method reveals chromosome locations in individual cell nucleus



Researchers have made a significant advancement toward understanding how the human genome is organized inside a single cell. This knowledge is crucial for analyzing how DNA structure influences gene expression and disease processes.
Published Do some mysterious bones belong to gigantic ichthyosaurs?



Several similar large, fossilized bone fragments have been discovered in various regions across Western and Central Europe since the 19th century. The animal group to which they belonged is still the subject of much debate to this day. A study could now settle this dispute once and for all: The microstructure of the fossils indicates that they come from the lower jaw of a gigantic ichthyosaur. These animals could reach 25 to 30 meters in length, a similar size to the modern blue whale.
Published Bacteria in cancer unmasked



Researchers have compiled a detailed catalogue of bacteria living in cancer metastases. Having analyzed over 4000 tumors, they shed light on the diversity of these co-inhabitants and how they might interact with cancer cells and their surroundings. For example, certain bacteria were linked to a worse response to immunotherapy. This study paves the way to a better understanding of how bacteria help or hinder cancer (therapy), and how we can use this for patients' advantage.
Published New diagnostic tool achieves accuracy of PCR tests with faster and simpler nanopore system



A new diagnostic tool developed by researchers can test for SARS-CoV-2 and Zika virus with the same or better accuracy as high-precision PCR tests in a matter of hours.
Published Different means to the same end: How a worm protects its chromosomes



Researchers have discovered that a worm commonly used in the study of biology uses a set of proteins unlike those seen in other studied organisms to protect the ends of its DNA.
Published Scientists grow 'mini kidneys,' revealing new insights into metabolic defects and potential therapy for polycystic kidney disease



Scientists have successfully grown 'mini kidneys' in the lab and grafted them into live mice, revealing new insights into the metabolic defects and a potential therapy for polycystic kidney disease.
Published Toothed whale echolocation organs evolved from jaw muscles



Genetic analysis finds evidence suggesting that acoustic fat bodies in the heads of toothed whales were once the muscles and bone marrow of the jaw.
Published Bringing multidrug-resistant pathogens to their knees



Multidrug-resistant bacterial infections that cannot be treated by any known antibiotics pose a serious global threat. A research team has now introduced a method for the development of novel antibiotics to fight resistant pathogens. The drugs are based on protein building blocks with fluorous lipid chains.
Published How plants adjust their photosynthesis to changing light



Light supplies the energy plants need to build up biomass. A research team is researching how plants adapt their photosynthesis to changing light. They describe a key molecular mechanism that synchronizes the processes involved.
Published How mosquito larva guts could help create highly specific insecticides



Did you know that the world's deadliest animal is the mosquito? And Aedes aegypti is one of the most dangerous. This bug spreads viruses that cause dengue fever, which was recently declared as an epidemic in Puerto Rico. Research reports new molecules that label proteins in the unique, alkaline environment of the Ae. aegypti digestive system that could help scientists develop insecticides to fight back.
Published Mediterranean marine worm has developed enormous eyes



Scientists are amazed at the discovery of a bristle worm with such sharp-seeing eyes that they can measure up to those of mammals and octopuses. The researchers suspect that these marine worms may have a secretive language, which uses UV light only seen by their own species. The advanced vision of such a primitive creature helps to finally settle an epic debate about the evolution of eyes.
Published Integrated dataset enables genes-to-ecosystems research



A new dataset bridging molecular information about the poplar tree microbiome to ecosystem-level processes has been released. The project aims to inform research regarding how natural systems function, their vulnerability to a changing climate, and ultimately how plants might be engineered for better performance as sources of bioenergy and natural carbon storage.
Published Can language models read the genome? This one decoded mRNA to make better vaccines



Researchers developed a foundational language model to decode mRNA sequences and optimize those sequences for vaccine development. The tool shows broader promise as a means for studying molecular biology.
Published Heat stress from ocean warming harms octopus vision



While climate change has led to an increase in the abundance of octopuses, heat stress from projected ocean warming could impair their vision and impact the survivability of the species.
Published Finds at Schöningen show wood was crucial raw material 300,000 years ago



During archaeological excavations in the Schoningen open-cast coal mine in 1994, the discovery of the oldest, remarkably well-preserved hunting weapons known to humanity caused an international sensation. Spears and a double-pointed throwing stick were found lying between animal bones about ten meters below the surface in deposits at a former lakeshore. In the years that followed, extensive excavations have gradually yielded numerous wooden objects from a layer dating from the end of a warm interglacial period 300,000 years ago. The findings suggested a hunting ground on the lakeshore.
Published Researchers envision sci-fi worlds involving changes to atmospheric water cycle



Human activity is changing the way water flows between the Earth and atmosphere in complex ways and with likely long-lasting consequences that are hard to picture. Researchers enlisted water scientists from around the globe to write story-based scenarios about the possible futures humanity is facing but perhaps can't quite comprehend yet. The results are part of a creative pathway to understand atmospheric water research with an eye towards the potential economic and policy issues that may be just beyond the horizon.
Published Tracing the largest solar storm in modern times from tree rings in Lapland



A research group was able to measure a spike in radiocarbon concentration of trees in Lapland that occurred after the Carrington flare. This discovery helps to prepare for dangerous solar storms.
Published New research offers insight into the future understanding of MS and its treatments



Researchers have developed a new and unique blood test to measure the immune response to the Epstein Barr Virus (EBV) which is the leading risk factor for developing multiple sclerosis (MS). Their findings have implications for future basic research in further understanding the biology of EBV in MS, but also has the potential to be applied in clinical trials that target the virus.
Published Heat flows the secret to order in prebiotic molecular kitchen



Biophysicists have demonstrated how heat flows through rock fissures could have created the conditions for the emergence of life.
