A fossilised insect wing discovered in an abandoned mine in Labrador has led palaeontologists from McGill University and the University of Gda?sk to identify a new hairy cicada species that lived around 100 million years ago.
Maculaferrum blaisi, described in a study published in Acta Palaeontologica Polonica, is the first hemipteran insect (true bug) to be discovered at the Redmond Formation, a fossil site from the Cretaceous period near Schefferville, Labrador.
AURORA, Colo. (Feb. 21, 2020) - Despite bureaucratic hurdles, the vast majority of pediatricians want to keep participating in a national program that provides vaccinations at no cost to children who are on Medicaid, uninsured, or who are American Indian/Alaska Native, according to researchers at the University of Colorado Anschutz Medical Campus.
What The Study Did: National vital statistics data from 2000 to 2016 were used to examine how rates of alcohol-induced deaths (defined as those deaths due to alcohol consumption that could be avoided if alcohol weren't involved) have changed in the U.S. and to compare the results by demographic groups including sex, race/ethnicity, age, socioeconomic status and geographic location. The study is accompanied by two commentaries.
What The Study Did: The risk of dementia in adults 60 and older who experience declines in both memory and gait speed was compared with adults who experience no decline or decline in either memory or gait speed only in this observational meta-analysis that included six studies with about 8,700 participants from the U.S. and Europe.

Scientists have recovered DNA from a well-preserved horned lark found in Siberian permafrost. The results can contribute to explaining the evolution of sub species, as well as how the mammoth steppe transformed into tundra, forest and steppe biomes at the end of the last Ice Age.
URBANA, Ill. - Starting weanling pigs off with the right diet can make all the difference for the health and productivity of the animal. A new University of Illinois study shows amino acids from a new torula yeast product are more digestible by young pigs than amino acids from fish meal.
Throughout typical development children must be surrounded by peers both for their well-being and for ample growth of their cognitive, linguistic, and social skills. In children with autism spectrum disorders (ASD), peer interaction is a core deficit. More specifically, young children with ASD (preschoolers) do not appear to show the same patterns as their typically developing counterparts along the three key domains associated with efficient peer interaction -- social interactive skills, play, and conversation.
MINNEAPOLIS, MN- February 21, 2020 - Researchers at the University of Minnesota Medical School discover a potential new way in which diet influences aging-related diseases.
A new study, led by Dr Tim DuBuc and Professor Uri Frank from the Centre for Chromosome Biology at NUI Galway, has found that Hydractinia, a North Atlantic jellyfish that also lives in Galway Bay, reproduces in a similar way to humans but does so far more flexibly.
Making everyday decisions seems easy enough. People know basic information about health and finances that they can use to inform their decision making. But new research from Stevens Institute of Technology suggests that too much knowledge can lead people to make worse decisions, pointing to a critical gap in our understanding of how new information interacts with prior knowledge and beliefs.
A new eye scan could help identify autism in children years earlier than currently possible.
The non-invasive eye scan utilises a hand-held device to find a pattern of subtle electrical signals in the retina that are different in children on the autism spectrum, which are directly linked to differences in their brain development.
A Simon Fraser University-led research team has found significant evidence that human activity in estuaries is impacting juvenile Pacific and Atlantic salmon. The team's review of 167 peer-reviewed studies (from an initial search of 13,000) identified negative impacts from several stressors, including the effects of flood-protecting tidal gates, pollution and habitat modification.
Their results were published today in Global Change Biology.
Philadelphia, February 21, 2020 - Prematurely born babies often need oxygen therapy to prevent brain damage or death. Unfortunately, excessive oxygen can damage immature lungs and cause severe life-long problems including bronchopulmonary dysplasia (BPD) and pulmonary hypertension (PH).
Mount Sinai Researchers find social isolation during key developmental windows drives long term changes to activity patterns of neurons involved in initiating social approach in an animal model.

A study by IRB Barcelona´s Development and Growth Control Laboratory, headed by ICREA researcher Marco Milán, reveals how Dpp and Wg morphogens regulate organ proportions and patterning of the fly wing through independent mechanisms. Given that these morphogens are present in vertebrates, these results are highly significant for understanding the development and growth of human limbs. "The regulatory mechanism that we describe in this study may pave the way to new research lines on malformations and congenital diseases in humans," says Marco Milán.
