A hidden threat facing one of Australia's most iconic birds has been uncovered in a new study. The critically endangered regent honeyeater once numbered in the hundreds of thousands, but their population has dwindled to fewer than 300. By analysing the DNA of museum specimens more than 100 years old and comparing it to modern samples, the team discovered that despite a population decline of 99 per cent, this has... Read more ›

Scientists say they have found a pattern of so-called epigenetic 'marks' in a transition state between normal and pancreatic cancer cells in mice, and that the normal cells may keep at least a temporary 'memory' of those cancer-linked marks. Read more ›

C. difficile (C. diff) is one of the most common and contagious hospital-acquired infections. Research has found that C. diff spreads more than three times more than previously thought. C. diff can spread covertly from surface to surface and remain undetected for weeks until it infects a patient. The results could spur more rigorous preventive measures that stop hidden spread of the disease. Read more ›

Antibiotic resistance is a global health challenge that could overtake cancer mortality within a few decades. In a new study, researchers show that the emergence of resistance can be understood in the mechanism of how bacteria build up defenses against being infected by viruses. It is about genes in the bacterium that interfere with the attacking virus's ability to multiply. Read more ›

New research shows how small shifts in the molecular makeup of a virus can profoundly alter its fate. These shifts could turn a deadly pathogen into a harmless bug or supercharge a relatively benign virus, influencing its ability to infect humans and cause dangerous outbreaks. Read more ›

Do physicians or artificial intelligence (AI) offer better treatment recommendations for patients examined through a virtual urgent care setting? A new study shows physicians and AI models have distinct strengths. The study compared initial AI treatment recommendations to final recommendations of physicians who had access to the AI recommendations but may or may not have reviewed them. Read more ›

A study followed the development of children's motor skills over a three-year period, from early childhood education to school age. The study showed that independent outdoor time and multisport activities support the development of motor competence. Even 30 minutes of outdoor time after a day at childcare makes a difference.

Researchers from chemistry, biology, and medicine are increasingly turning to AI models to develop new hypotheses. However, it is often unclear on which basis the algorithms come to their conclusions and to what extent they can be generalized. A publicationnow warns of misunderstandings in handling artificial intelligence. At the same time, it highlights the conditions under which researchers can most likely have confidence in the models.

The scent of blooming flowers and fresh plant life is not just a perk of springtime; it is a key driver in the survival and evolution of butterflies and moths. New research reveals how the daily cycles of plant aromas are linked to the dietary habits and evolution of the winged insects collectively known as Lepidoptera. Read more ›

Drug-carrying DNA aptamers can deliver a one-two punch to leukemia by precisely targeting the elusive cancer stem cells that seed cancer relapses, researchers at the University of Illinois Urbana-Champaign report. The aptamers -- short single-strand snippets of DNA that can target molecules like larger antibodies do -- not only deliver cancer-fighting drugs, but also are themselves toxic to the cancer stem cells, the researchers said.

An archaeological study of human settlement during the Final Palaeolithic revealed that populations in Europe did not decrease homogenously during the last cold phase of the Ice Age. Significant variation in regional population sizes indicate differentiated reactions nested in an overall shift of settlement areas towards the east. Read more ›
