Using high quality molecular data, researchers have re-investigated a long-standing question about the position of two phyla of small aquatic invertebrates -- Kamptozoa and Bryozoa -- on the evolutionary tree.

Recently, a group of 23 science and policy experts from the U.S. and Canada published a review of mining risks to watersheds ranging from Montana to British Columbia and Alaska. The paper brought together experts in salmon ecology, watershed science, mining impacts and mining policy to integrate knowledge across research fields that often work independently from one another.
Researchers are developing precision optical sensors for telescopes and observatories. The team has now improved the spectra resolution of their superconducting sensor, a major step in their ultimate goal: analyzing the composition of exoplanets.
The fossil record tells us about ancient life through the preserved remains of body parts like bones, teeth and turtle shells. But how to study the history of soft tissues and organs, which can decay quickly, leaving little evidence behind? In a new study, scientists use gene expression patterns, called transcriptomics, to investigate the ancient origins of one organ: the placenta, which is vital...
Researchers report the development of a chemical-based sequencing method to quantify different epigenetic markers simultaneously. Their method, called NT-seq, short for nitrite treatment followed by next-generation sequencing, is a sequencing method for detecting multiple types of DNA methylation genome-wide.
Scientists have developed a new CRISPR-based technology that could offer a safer approach to correcting genetic defects. The new 'soft' CRISPR approach makes use of natural DNA repair machinery, providing a foundation for novel gene therapy strategies with the potential to cure a large spectrum of genetic diseases.
There is new evidence that ancient high latitudes, to which early dinosaurs were largely relegated, regularly froze over, and that the creatures adapted -- an apparent key to their later dominance.
A new article synthesizes the impact of metal and coal mines on salmon and trout in northwestern North America, and highlights the need for more complete and transparent science to inform mining policy.
Scientists have discovered a convergent mechanism that may be responsible for how two top-ranked genetic risk factors for autism spectrum disorder/intellectual disability (ASD/ID) lead to these neurodevelopmental disorders.
The World Health Organization (WHO) recently listed a new sibling diagnosis for post-traumatic stress disorder (PTSD), termed complex post-traumatic stress disorder (CPTSD). An international team has now summarized the symptoms of the long-awaited new diagnosis and issued guidelines for clinical assessment and treatment.
Researchers improve a widely used simulation method for high-performance computing clusters.
DNA testing reveals that the wild ancestors of the common domestic and feral pigeons, now extinct in many parts of the world, are still living on islands in Scotland and Ireland.
A 15-year study details the origins and diversity of every known mineral on Earth, a landmark body of work that will help reconstruct the history of life on Earth, guide the search for new minerals and ore deposits, predict possible characteristics of future life, and aid the search for habitable planets and extraterrestrial life.
Neurodegenerative diseases like Alzheimer's and Parkinson's are defined by pathogenic accumulation of toxic proteins in the brain. Now, however, scientists have established that the p62 protein, which is involved in cellular protein degradation, can prevent the accumulation of toxic oligomeric tau species in mouse brains, proving the 'neuroprotective' function of p62 in a living model.
Adolescents are over three times more vulnerable to developing a cannabis addiction than adults, but may not be at increased risk of other mental health problems related to the drug, according to a new study.
Pesticides and heavy metals in soil may have detrimental effects on the cardiovascular system, according to a review paper.
A new study has found humpback whales can learn incredibly complex songs from whales from other regions.
Songbirds learning from nearby birds that food supplies might be growing short respond by changing their physiology as well as their behavior, research shows.
HIV has an 'early and substantial' impact on aging in infected people, accelerating biological changes in the body associated with normal aging within just two to three years of infection, according to new research.
After the Big Bang came the earliest galaxies. Due to the expansion of the universe, these galaxies are receding away from us. This causes their emissions to be redshifted (shifted towards longer wavelengths). By studying these redshifts, it is possible to characterize the 'motion' within the galaxies as well as their distance. In a new study, astronomers have now revealed a likely rotational...
A research team develops a sound-sensing skin-attachable acoustic sensor. The new sensor decreased in size and increased in flexibility and is applicable as auditory electronic skin.
Researchers investigating the exposure of small mammals to plastics in England and Wales have found traces in the feces of more than half of the species examined. The densities of plastic excreted were comparable with those reported in human studies.
Many antibody tests have been developed since the pandemic started, but very few are designed to specifically detect the Sars-CoV-2 neutralizing antibodies which prevent infection. Based on protein complementation, the modular method described here is the first of its kind to measure neutralizing antibodies against variants, from a drop of blood, in under one hour and at low cost.
Researchers have developed a rapid and effective antibody detection method for SARS-CoV-2 that is minimally invasive and applicable in resource-limited settings. Their methodology, which uses a patch sensor containing porous microneedles and a paper-based immunoassay, could have far-reaching implications for the blood-free detection of COVID-19 and many other infectious diseases.
New research finds that machine-learning algorithms can help health care staff distinguish the two conditions. Researchers show how algorithms may be effective predictive tools using a few simple variables and routinely available structured clinical information.
