Mothering in domestic violence: Protecting children behind closed doors
Almost all land plants employ an army of molecular editors who correct errors in their genetic information. Together with colleagues from Hanover, Ulm and Kyoto (Japan), researchers from the University of Bonn have now transferred one of these proofreaders from the moss Physcomitrium patens (previously known as Physcomitrella patens) into a flowering plant. Surprisingly, it performs its work there...
National survey on COVID-19 pandemic shows significant mental health impact
As emerging data shows an alarming rise of domestic violence during the pandemic, researchers at the University of South Australia are urging practitioners to look beyond clinical observations and focus on the strengths that mothers exercise to protect their children from domestic abuse.
New algorithm for personalized models of human cardiac electrophysiology
The findings of a nationwide survey assessing the effects of the COVID-19 pandemic on the emotional wellbeing of U.S. adults show 90 percent of survey respondents reported experiencing emotional distress related to the pandemic.
New candidate for raw material synthesis through gene transfer
Researchers from the Moscow Institute of Physics and Technology, Kazan Federal University, and George Washington University have proposed an algorithm for producing patient-specific mathematical models describing the electrical excitation of human heart cells. The study looks at two possible approaches -- one using experimental records of electrical activity and the other based on gene expression...
New Human Gene Therapy editorial: Concern following gene therapy adverse events
Cyanobacteria hardly need any nutrients and use the energy of sunlight. Bathers are familiar with these microorganisms as they often occur in waters. A group of researchers at the Karlsruhe Institute of Technology (KIT) has discovered that the multicellular species Phormidium lacuna can be genetically modified by natural transformation and could thus produce substances such as ethanol or hydrogen....
New light-based method for faster and 'green' production of building blocks for medicines
Response to the recent report of the deaths of two children receiving high doses of a gene therapy vector (AAV8) in a Phase I trial for X-linked myotubular myopathy (MTM). The news "is a tragic reminder of how difficult it is to predict outcomes in first-in-human studies
New method measures temperature within 3D objects
Researchers at Eindhoven University of Technology (TU/e), the Netherlands have developed a new method to convert gaseous, low-weight hydrocarbons into more complex molecules by illuminating the hydrocarbons with light in the presence of a suitable catalyst.
New method reveals how the Parkinson's disease protein damages cell membranes
University of Wisconsin-Madison engineers have made it possible to remotely determine the temperature beneath the surface of certain materials using a new technique they call depth thermography. The method may be useful in applications where traditional temperature probes won't work, like monitoring semiconductor performance or next-generation nuclear reactors.
New platform gauges effects of plastic nanoparticles on human development and health
In sufferers of Parkinson's disease, clumps of α-synuclein (alpha-synuclein), sometimes known as the 'Parkinson's protein', are found in the brain. These destroy cell membranes, eventually resulting in cell death. Now, a new method developed at Chalmers University of Technology, Sweden, reveals how the composition of cell membranes seems to be a decisive factor for how small quantities of...
New sequencing technology will help scientists decipher disease mechanisms
A study released today in STEM CELLS outlines a new platform researchers designed that allowed them to investigate the potentially harmful effects of microplastics and nanoplastics.
New technique in which drugs make bacteria glow could help fight antibiotic resistance
New technologies capable of sequencing single molecules in fine detail will help scientists better understand the mechanisms of rare nucleotides thought to play an important role in the progression of some diseases.
New weapons for fighting Devil disease
A new technique could help reduce antibiotic prescribing by predicting which drugs could be effective in fighting bacteria within minutes.
New, more infectious strain of COVID-19 now dominates global cases of virus
Researchers at the University of Tasmania's Menzies Institute for Medical Research and the School of Medicine have added an arsenal of new tools (video link) to their repertoire for fighting the insidious Devil Facial Tumour Disease.
Newer variant of COVID-19-causing virus dominates global infections
Researchers have shown that a variation in the viral genome of Covid-19 improved its ability to infect human cells and helped it become the dominant strain circulating around the world today.
Number of HIV-1 founder variants determined by source partner infection
Research out today in the journal Cell shows that a specific change in the SARS-CoV-2 coronavirus virus genome, previously associated with increased viral transmission and the spread of COVID-19, is more infectious in cell culture.
Oat and rye bran fibres alter gut microbiota, reducing weight gain and hepatic inflammation
For people infected by HIV in the subset of cases involving several variants of the virus, and for which disease progression is usually faster, a new modeling study suggests the number of infection-initiating viral variants is primarily determined by how long the source partner has been infected.
Oropharyngeal secretions may help reduce false negative COVID-19 test results
In a newly published experimental study, the consumption of dietary fibre from oat and rye brans supported the growth of beneficial gut microbiota, which in turn ameliorated cholesterol metabolism, enhanced gut barrier function and reduced hepatic inflammation. In addition, diets enriched with oat or rye bran were shown to attenuate weight gain. The effects of oat and rye were partly different,...
Patients may be exposed to hormone-disrupting chemicals in medication, medical supplies
A new study published in the Journal of Dental Research demonstrates that testing of oropharyngeal secretions may reduce the number of false negative results from nasal swab testing of patients who have seemingly recovered from the disease.
Popular chemotherapy drug may be less effective in overweight and obese women
Health care providers may unintentionally expose patients to endocrine- disrupting chemicals (EDCs) by prescribing certain medications and using medical supplies, according to a perspective published in the Endocrine Society's Journal of Clinical Endocrinology & Metabolism.
Prospective teachers misperceive Black children as angry
Breast cancer patients who are overweight or obese might benefit less from treatment with docetaxel, a common chemotherapy drug, than lean patients, a new study finds.
Putting zinc on bread wheat leaves
Prospective teachers appear more likely to misperceive Black children as angry than white children, which may undermine the education of Black youth, according to new research published by the American Psychological Association.
Research news tip sheet: Story ideas from Johns Hopkins Medicine
Applying zinc to the leaves of bread wheat can increase wheat grain zinc concentrations and improve its nutritional content.
Research reflects how AI sees through the looking glass
The latest Johns Hopkins Medicine research achievements and clinical advances, covering topics not related to COVID-19 or the SARS-CoV-2 virus.
Researchers examine refugee children's academic, social, and emotional learning outcomes
Intrigued by how reflection changes images in subtle and not-so-subtle ways, a team of Cornell University researchers used artificial intelligence to investigate what sets originals apart from their reflections. Their algorithms learned to pick up on unexpected clues such as hair parts, gaze direction and, surprisingly, beards - findings with implications for training machine learning models and...
Researchers at Global TIES for Children, an international research center based at NYU Abu Dhabi and NYU New York, examined a variety of post-migration risks faced by Syrian refugee children enrolled in Lebanese public schools and found that students being older than expected for the grade in which they were placed was most consistently and strongly associated with developmental and learning...
