KNOXVILLE, Tenn.--Researchers at the University of Tennessee Institute of Agriculture's Amphibian Disease Laboratory are working to understand--and hopefully get ahead of--highly contagious pathogens affecting amphibians in Europe and Asia. One of the pathogens of interest is Batrachochytrium salamandrivorans, or Bsal.
New research suggests that large-scale environmental factors influence the size of one of the ocean's most abundant forage species. Recently, scientists from LSU, NOAA, the University of Southern Mississippi and the University of Maryland Center for Environmental Science evaluated large-scale ecosystem dynamics influencing growth of menhaden in the Gulf of Mexico and the Atlantic Ocean. They found that anthropogenic influences affected menhaden in the Atlantic more than in the Gulf, where environmental factors were the more dominant predictors of growth.
Toronto - Whether it's blocking traffic outside a Donald Trump rally or preventing women from entering an abortion clinic, social activists take a risk when they choose extreme tactics to make their point.
New research has found that social change advocates face an "activist's dilemma." While extreme actions can bring more attention to a cause than moderate ones, they are more likely to diminish support, even among natural sympathizers, the study found.
Black carbon (BC) measurements in Antarctica are still scarce, but necessary to understand the particle's effect in our climate, says Luciano Marquetto, a Ph.D. student from the Polar and Climatic Center, Federal University of Rio Grande do Sul, Brazil.
Emitting light from silicon has been the 'Holy Grail' in the microelectronics industry for decades. Solving this puzzle would revolutionize computing, as chips will become faster than ever. Researchers from Eindhoven University of Technology now succeeded: they have developed an alloy with silicon that can emit light. The results have been published in the journal Nature. The team will now start creating a silicon laser to be integrated into current chips.
The tragic COVID-19 pandemic is creating new awareness regarding the importance of breathing problems, pneumonia and ventilators. What many people don't realize is that without anesthesia and operating room ventilators, the millions of surgeries normally performed each year in the U.S. would be impossible.
There is evidence that climate change affects both the quantity and quality of food production, reducing food security, and nutrition intake. In developing countries, where the agricultural sector dominates the economy, the impacts of the changing climate on the agricultural supply chain will substantially hinder economic growth and well-being of the local communities.
No matter where we look, the same rules apply everywhere in space: countless calculations of astrophysics are based on this basic principle. A recent study by the Universities of Bonn and Harvard, however, has thrown this principle into question. Should the measured values be confirmed, this would toss many assumptions about the properties of the universe overboard. The results are published in the journal Astronomy & Astrophysics, but are already available online.
Amsterdam, NL, April 8, 2020 - Clinical neuropsychology and psychology have evolved as diagnostic and treatment-oriented disciplines necessary for individuals with neurological, psychiatric, and medical conditions.
A homogeneous, consistent, high-quality in situ temperature data set covering some decades in time is crucial for the detection of climate changes in the ocean.
The Biological Dynamics of Forest Fragments Project (BDFFP), located near Manaus, Brazil, began in 1979 and is the world's longest-running experimental study of tropical forest fragments. A new paper in The Condor: Ornithological Applications summarizes four decades of data from the project about how Amazonian bird communities respond to habitat fragmentation, a question as relevant today as ever in light of the recent increase in deforestation in the Amazon.
In a recent Journal of Sleep Research study, participants perceived pleasant and neutral pictures in a more negative way when their sleep was restricted for several nights in a row.
In the study, participants were tested the morning after 5 nights of regular sleep and after 5 consecutive nights of sleep restriction (5 hours a night).
From early prenatal development through childhood, the prefrontal cortex of the human brain undergoes an avalanche of developmental activity. In some cases, it also contains seeds of neuropsychiatric illnesses such as autism spectrum disorder and schizophrenia, according to a new genetic analysis led by researchers at Yale University and the University of California-San Francisco (UCSF).
For infants as young as four months, a hug from a parent makes all the difference. A study appearing April 7 in the journal iScience examined heart rate responses in infants less than one year old during a hug and found that children as young as four months experience greater heart rate slowing during a hug than a hold--and during a hug from their parent as compared to a hug from a stranger. The researchers say that the study offers some of the first evidence that hugs play an important role in early bonding between parents and their children.
Adults talk to babies differently from how we would speak to other adults. Compared to how adults speak, speech directed at babies tends to have a higher, more varied pitch, greater positive affectation, it is slower and involves shorter phrases. The characteristics of this speech targeting babies has been studied extensively and it has been found that it is a common feature of different cultures.
