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. |
| 'Soft' CRISPR may offer a new fix for genetic defects Posted: 01 Jul 2022 11:31 AM PDT 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. |
| Dinosaurs took over amid ice, not warmth, says a new study of ancient mass extinction Posted: 01 Jul 2022 11:31 AM PDT 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. |

| New sibling diagnosis for post-traumatic stress disorder Posted: 01 Jul 2022 08:31 AM PDT 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. |

| Rare wild ancestors of feral pigeons found living on British and Irish islands Posted: 01 Jul 2022 08:31 AM PDT 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. |
| Posted: 01 Jul 2022 07:28 AM PDT 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. |
| Protecting the brain from dementia-inducing abnormal protein aggregates Posted: 01 Jul 2022 07:27 AM PDT 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. |
| Scientists warn of links between soil pollution and heart disease Posted: 01 Jul 2022 07:27 AM PDT Pesticides and heavy metals in soil may have detrimental effects on the cardiovascular system, according to a review paper. |
| Whales learn songs from each other in a cultural 'deep dive' Posted: 01 Jul 2022 07:27 AM PDT A new study has found humpback whales can learn incredibly complex songs from whales from other regions. |
| HIV speeds up body's aging processes soon after infection, study shows Posted: 01 Jul 2022 07:27 AM PDT 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. |
| Capturing the onset of galaxy rotation in the early universe Posted: 01 Jul 2022 07:27 AM PDT 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 motion of one such distant galaxy. |
| Hearing better with skin than ears Posted: 01 Jul 2022 07:27 AM PDT 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. |
| Posted: 01 Jul 2022 07:27 AM PDT 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. |
| Plug-and-play test for keeping track of immunity to Sars-CoV-2 variants Posted: 01 Jul 2022 07:27 AM PDT 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. |
| Posted: 01 Jul 2022 07:27 AM PDT 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. |
| Floating in space might be fun, but study shows it's hard on earthly bodies Posted: 30 Jun 2022 10:48 AM PDT Bone loss happens in humans -- as we age, get injured, or any scenario where we can't move the body, we lose bone. Understanding what happens to astronauts and how they recover is incredibly rare. It lets us look at the processes happening in the body in such a short time frame. We would have to follow someone for decades on Earth to see the same amount of bone loss. |
| Study reveals an unprecedented change in Europe's fire regime Posted: 30 Jun 2022 08:45 AM PDT A study reveals an unprecedented change in the fire regime in Europe which is related to climate change. The affected areas are in Southern, Central and Northern Europe but this historical change in Europe's fire regime is more intense in the Mediterranean area. |
