In response to the COVID-19 pandemic, a majority of schools across the U.S. shifted to virtual learning. In a new study, published in Social Education Research, researchers conducted interviews with parents of students who attended middle or high schools to understand how virtual learning impacted their daily routines, stress levels, and the academic performance of the children. The transition to virtual learning necessitated the creation of online lessons in a very short time period and with limited training of teachers. As a result, parents and students had to deal with unexpected changes in their home lives and learning environments. “Virtual learning will not be limited ...

Previous scientific studies have indicated that North American dog lineages were replaced with European ones between 1492 and the present day. To better understand the timing of this replacement, researchers from the University of Illinois Urbana-Champaign and the University of Iowa sequenced mitochondrial DNA from archaeological dogs. Their findings suggest a complex social history of dogs during the early colonial period.  Europeans and Native Americans valued their dogs as companion animals, using them for similar work and as symbols of identity. Consequently, ...

With escalating concerns about the enduring impact of plastic waste, phytoremediation emerges as a promising solution. This method utilizes plants ...

For the decades since their discovery, seismic signals known as PKP precursors have challenged scientists. Regions of Earth’s lower mantle scatter incoming seismic waves, which return to the surface as PKP waves at differing speeds. The origin the precursor signals, which arrive ahead of the main seismic waves that travel through Earth’s core, has remained unclear, but research led by University of Utah geophysicists sheds new light on this mysterious seismic energy. PKP precursors appear to propagate from places deep below North America and the western Pacific and possibly bear an association with “ultra-low velocity zones,” thin layers ...

Inherited diseases of metabolism and immunity have more in common than previously recognized, according to a new study published in the journal Science Immunology. The findings point to a new set of metabolic genes that are important for the function of immune system T cells, and they offer insights that could improve care for patients with these disorders.  The study examined genes that cause inborn errors of metabolism (disorders of the processes that cells use to convert food to energy) and inborn errors of immunity (disorders that affect immune system function). These rare and complex diseases are not fully understood.  “There had previously ...

The Earth’s nitrogen cycle is among the most heavily exceeded planetary boundaries. Agricultural production and fossil fuel burning release nitrogen pollutants like ammonia (NH3), nitrogen oxides (NOx), and nitrous oxide (N2O), which contribute to air pollution and damage ecosystems. These pollutants harm human health, crops, and ecosystems. Given the growing global energy and food demand, this damage is expected to increase even further. The potential of nitrogen pollution mitigation technologies ...

More than 70 genes have been linked to autism spectrum disorder (ASD), a developmental condition in which differences in the brain lead to a host of altered behaviors, including issues with language, social communication, hyperactivity, and repetitive movements. Scientists are attempting to tease out those specific associations gene by gene, neuron by neuron. One such gene is Astrotactin 2 (ASTN2). In 2018, researchers from the Laboratory of Developmental Neurobiology at Rockefeller University discovered how defects in the protein produced by the gene disrupted ...

Many scientists in the weather radar community have CVD and the use and interpretation of color is an important aspect of their work. Most colormaps ...

A new scientific review explores the exciting potential of hot carriers, energetic electrons generated by light in plasmonic nanostructures. These tiny structures hold immense promise for future technologies due to their unique way of interacting with light and creating hot carriers.   Hot carriers are electrons with a surplus of energy. When light strikes a plasmonic nanostructure, it can excite these electrons, pushing them out of equilibrium. This non-equilibrium state unlocks a range of fascinating phenomena. Hot carriers can be used to control light itself, potentially leading to ...

New research from Smithsonian’s Bird Friendly Coffee program highlights a type of biodiversity that often gets overlooked: soil bacteria and fungal communities. For over twenty years, Smithsonian research has shown that coffee farms with shade trees protect more biodiversity than intensified, monoculture coffee farms. The new research, published today in Applied Soil Ecology, shows that soil bacteria and fungi on coffee farms also respond to the intensity of coffee farm management. To conduct this research, the team collected soils samples on coffee farms in Colombia, El Salvador, and Peru and used DNA analysis to profile bacterial and fungal soil on ...

Geoscientists from the University of Cologne have led an international study to determine the origin of the huge piece of rock that hit the Earth around 66 million years ago and permanently changed the climate. The scientists analysed samples of the rock layer that marks the boundary between the Cretaceous and Paleogene periods. This period also saw the last major mass extinction event on Earth, in which around 70 percent of all animal species became extinct. The results of the study published in Science indicate that the asteroid formed outside Jupiter’s orbit during the ...

Powerful telescopes like NASA’s Hubble, James Webb, and Chandra X-ray Observatory provide scientists a window into deep space to probe the physics of black holes. While one might wonder how you can “see” a black hole, which famously absorbs all light, this is made possible by tidal disruption events (TDEs) - where a star is destroyed by a supermassive black hole and can fuel a “luminous accretion flare.” With luminosities thousands of billions of times brighter than the Sun, accretion events enable astrophysicists to study supermassive black holes (SMBHs) at cosmological distances. TDEs occur when a star is violently ripped ...
