As scientists work to determine why some of the latest climate models suggest the future could be warmer than previously thought, a new study indicates the reason is likely related to challenges simulating the formation and evolution of clouds.
Twitter posts reveal polarization in Congress on COVID-19
- ScienceDaily
- 20/6/24 21:15
The rapid politicization of the COVID-19 pandemic can be seen in messages members of the US Congress sent about the issue on the social media site Twitter, a new analysis found. Using artificial intelligence and resources from the Ohio Supercomputer Center, researchers conducted an analysis that covered all 30,887 tweets that members sent about COVID-19 from the first one on Jan. 17 through March...
Genes affecting brains and brawn?
- ScienceDaily
- 20/6/24 21:15
Genes located in 'copy number variants' (CNVs) -- parts of chromosomes that are missing in some individuals and duplicated in others -- that are associated with neurodevelopmental disorders affect more than just brain development, according to new research.
Rogue's gallery of dusty star systems reveals exoplanet nurseries
- ScienceDaily
- 20/6/24 21:15
The Gemini Planet Imager on the Gemini South telescope looked at 104 young, nearby stars, 10-100 million years old, in search of debris disks. It found 26, 25 of which had inner holes indicating a planet. These debris rings, similar to the Kuiper Belt in our solar system, display amazing diversity in size and distance from the star. Such studies help astronomers understand the formation of planets...
Effects from low-level concentrations of harmful chemicals preserved in three generations of fish
- ScienceDaily
- 20/6/24 21:15
Fish exposed to very low levels of chemicals commonly found in waterways can pass the impacts on to future generations that were never directly exposed to the chemicals, according to researchers.
Plug-and-play lens simplifies adaptive optics for microscopy
- ScienceDaily
- 20/6/24 21:15
Researchers have developed a new plug-and-play device that can add adaptive optics correction to commercial optical microscopes. Adaptive optics can greatly improve the quality of images acquired deep into biological samples, but has, until now, been extremely complex to implement.
Entry point for curbing the evolution of antibiotic resistance discovered
- ScienceDaily
- 20/6/24 21:15
Medical researchers have developed a new approach to improving the effectiveness of antibiotics in bacterial infections. The study outlines ways to controlling antibiotic resistance through targeted gene interactions.
Adirondack boreal peatlands near southern range limit likely threatened by warmer climate
- ScienceDaily
- 20/6/24 21:15
A study documents an invasion happening in the Adirondacks: the black spruce, tamarack, and other boreal species are being overcome by trees normally found in warmer, more temperate forests. Ultimately, researchers predict that these invaders could overtake a variety of northern species, eliminating trees that have long been characteristic of wetlands like Shingle Shanty Preserve in the...
A shorter IQ test for children with special needs
- ScienceDaily
- 20/6/24 21:15
For decades, neuropsychologists have used the Wechsler Intelligence Scale for Children test as the gold-standard intelligence quotient (IQ) test to determine the intellectual abilities of children with special needs. However, this comprehensive test can take up to 2 hours to complete, and many children with special needs have a difficult time participating in such long tests.
Better way to keep birds from hitting power lines
- ScienceDaily
- 20/6/24 21:15
Suspended, rotating devices known as ''flappers'' may be the key to fewer birds flying into power lines, a new study suggests.
Self-powered alarm fights forest fires, monitors environment
- ScienceDaily
- 20/6/24 21:15
Scientists designed and fabricated a remote forest fire detection and alarm system powered by nothing but the movement of the trees in the wind.
Adirondack boreal peatlands near southern range limit likely threatened by warmer climate
A study published in the journal Wetlands documents an invasion happening in the Adirondacks: the black spruce, tamarack, and other boreal species are being overcome by trees normally found in warmer, more temperate forests. Ultimately, researchers from the SUNY College of Environmental Science and Forestry (ESF) predict that these invaders could overtake a variety of northern species, eliminating...
Study examines media coverage of protests worldwide
As anti-racism solidarity protests continue around the world, new research suggests mainstream media have a tendency to focus on the violence and spectacle of a protest rather than the substance. That mentality and approach need to change according to Summer Harlow, assistant professor of journalism at the University of Houston Jack J. Valenti School of Communication.
Entry point for curbing the evolution of antibiotic resistance discovered
The team of Professor Tobias Bollenbach from the Institute for Biological Physics at the University of Cologne has published a study on a new approach to improving the effectiveness of antibiotics in bacterial infections. The study 'Highly parallel lab evolution reveals that epistasis can curb the evolution of antibiotic resistance,' on ways to controlling antibiotic resistance through targeted...
Study suggests light environment modifications could maximize productivity
The crops we grow in the field often form dense canopies with many overlapping leaves, such that young "sun leaves" at the top of the canopy are exposed to full sunlight with older "shade leaves" at the bottom. In order to maximize photosynthesis, resource-use efficiency, and yield, sun leaves typically maximize photosynthetic efficiency at high light, while shade leaves maximize efficiency at low...

Suspended, rotating devices known as "flappers" may be the key to fewer birds flying into power lines, a study by Oregon State University suggests.
Harmful effects of wildfire smoke are immediate and could make COVID-19 symptoms worse, UBC study warns
A study by University of British Columbia researchers underscores the immediate, harmful health effects of wildfire smoke and says there are concerning implications during the COVID-19...

Scientists identify the mechanism that regulates mitochondrial energy production
Scientists at the Centro Nacional de Enfermedades Cardiovasculares (CNIC) have identified the molecular mechanism by which mitochondria, the main source of the cell's energy supply, regulate their function to optimize energy production in order to meet the body's changing needs. The discovery, published in the journal Science Advances, helps to explain how the body regulates its metabolism.
Analysis of rates of police-related fatalities finds significant race-related differences
A study analyzing and describing US police-involved fatalities across racial/ethnic groups at the level of individual metropolitan statistical areas publishes June 24, 2020 in the open-access journal PLOS ONE, by Gabriel Schwartz and Jaquelyn Jahn from the Harvard T.H. Chan School of Public Health.
Antarctic penguins happier with less sea ice
Researchers have been surprised to find that Adélie penguins in Antarctica prefer reduced sea ice conditions, not just a little bit, but a lot. As climate models project rapid reduction of the continent's sea ice over the rest of the century, this iconic polar predator could be a rare global warming winner. Their research findings are published on June 24, 2020 in Science Advances.
