Researchers have found a causal link between caesarean section birth, low intestinal microbiota and peanut sensitivity in infants, and they report the effect is more pronounced in children of Asian descent than others, in a recently published paper in the journal of the American Gastroenterological Association.
When disease outbreaks happen, response time in developing and distributing treatments is crucial to saving lives. Unfortunately, developing custom drugs as countermeasures is often a slow and difficult process.
A new study is the first-ever to identify the genes for creativity in Homo sapiens that distinguish modern humans from chimpanzees and Neanderthals. The research identified 267 genes that are found only in modern humans and likely play an important role in the evolution of the behavioral characteristics that set apart Homo sapiens, including creativity, self-awareness, cooperativeness, and healthy longevity.
It has been a long pursuit to develop super-resolution imaging techniques for Raman microscopy, which has intrinsic advantages of chemical specificity over the fluorescence counterpart. Despite the perceived importance and extensive research efforts, true super-resolution (defined as diffraction-unlimited) Raman imaging of biological systems in the optical far-field remains challenging due to the deficiency in sensitivity for conventional Raman scattering.
DALLAS, April 21, 2021 -- A smartphone-based electrocardiogram (ECG) screening accurately detected previously unknown atrial fibrillation in American Indians, and more than half who were diagnosed with the irregular heart rhythm were younger than the recommended screening age of 65, according to new research published today in the Journal of the American Heart Association, an open access journal of the American Heart Association.
An analysis of published studies indicates that pharmacist-led efforts can reduce medication-related harms--such as cognitive impairment, falls, drug-drug interactions, and bacterial infections--in older adults in residential aged care facilities. The findings are published in the British Journal of Clinical Pharmacology.
Following a school shooting, the risk for additional school shootings in the same and neighboring states increases in the next year, according to an analysis published in Contemporary Economic Policy.
The analysis included information on U.S. school shootings between 1990 and 2017. The copycat effect revealed by the analysis indicates that the media should find a way to cover these events while minimizing the risk of provoking additional shootings.
An article published in Geographical Research examines how the COVID-19 pandemic has impacted international higher education and the mobility of students around the globe, noting that universities face the urgent task of reimagining alternative futures for themselves.
Microplastics--small plastic pieces less than 5 millimeters in length--are ubiquitous in the environment, and they can have significant effects on wildlife. A new study published in Environmental Toxicology and Chemistry reveals that there are multiple impacts of different microplastics--with varying sizes, shapes, and chemical makeup--to the survival, growth, and development of larval fathead minnows, an important prey species in lakes and rivers in North America.
Kiwi are iconic birds that have been severely impacted by deforestation and predation from invasive mammals since the arrival of humans in New Zealand. The remaining kiwi can be split into 14 clusters that are now treated as separate conservation management units. A review published in Ibis examines the latest information on kiwi genetics to investigate the legitimacy for maintaining these differences.
Despite virtual reality (VR) technology being more affordable than ever, developers have yet to achieve a sense of full immersion in a digital world. Among the greatest challenges is making the user feel as if they are walking.
Marine ecosystems are in the midst of a conservation crisis, with coral reefs in particular facing numerous challenges as a result of climate change. In an effort to better understand these environments and the threats they face, researchers collect huge image libraries of these underwater environments, using 3D imagery collected from divers and snorkelers, as well as 2D images collected from satellites. These approaches provide researchers with huge amounts of data, but to extract value from these libraries requires a method to quickly analyze for patterns or 'classifications'.
Humans and animals have a preferred walking speed. This is, in part, influenced by the amount of energy required: they prefer to walk at the speed at which they use the lowest possible amount of energy. One of the ways to achieve this is using something called resonance.
Listening to music before going to be can improve sleep quality among older adults, according to an analysis of all relevant published clinical trials.
