Enrollment of low-income, undocumented students declined by half at University of California and California State University campuses from 2016 through the 2022-23 academic year, according to a new study by the University of California Civil Rights Project at UCLA and UC Davis School of Law.  The paper, “‘California Dreamin’: DACA’s Decline and Undocumented College Student Enrollment in the Golden State” is believed to be the first to report on data collected during an era marked by increasing limitations on DACA, or Deferred Action for Childhood Arrivals.  Further, researchers found, for UC and CSU low-income undocumented ...

One of the things that makes brains so incredibly difficult to understand is their ability to adjust and adapt. Our learning experiences can set off complex signaling cascades that reshape neurons—and their synaptic connections—at the cellular level. For example, in mammals, scientists have established that activation of the N-methyl-D-aspartate receptor (NMDAR) and the ensuing calcium ion (Ca2+)-dependent signaling cascade is essential for postsynaptic remodeling and learning. As one might reasonably expect, ...

Samarium (Sm), a rare earth metal, is important to organic chemists because of the ability of its divalent compounds to efficiently perform single-electron transfer reductions. Samarium iodide (SmI2) is moderately stable and can operate under mild conditions at room temperature, making it highly useful for producing pharmaceuticals and biologically active materials. However, most reactions require SmI2 in quantities equal to or greater than the stoichiometric amount and necessitate the use of harmful chemicals, making the process resource-intensive and expensive to manage.   Several approaches have been studied to reduce ...

Scientists have learned how plants keep viruses from being passed to their offspring, a finding that could ensure healthier crops. The discovery could also help reduce the transmission of diseases from mothers to human children. Plant viruses are often able to spread from one country to another through the seed trade. As a result, parent-to-progeny disease transmission is of global concern. “Viruses can hide in seeds for years, making this one of the most important issues in agriculture,” said UC Riverside distinguished professor Shou-Wei Ding in the Department of Microbiology and Plant Pathology. Ding is corresponding author of a new paper about the ...

Fukuoka, Japan – Japan in spring is famous for its cherry blossoms, or sakura, which begin flowering in the southern region of Kyushu and blaze upwards to the remote north of Hokkaido. The most abundant cherry tree cultivar, Somei Yoshino, is the iconic symbol of spring, as the cloned trees flower simultaneously at each site, creating a fleeting explosion of white-pink blossom that enraptures locals and tourists alike. The flowering forecasts of Somei Yoshino are poured over for months before flowering, as visitors plan their trips and locals ...

Fukuoka, Japan—Researchers have developed a new organic thermoelectric device that can harvest energy from ambient temperature. While thermoelectric devices have several uses today, hurdles still exist to their full utilization. By combining the unique abilities of organic materials, the team succeeded in developing a framework for thermoelectric power generation at room temperature without any temperature gradient. Their findings were published in the journal Nature Communications. Thermoelectric devices, or thermoelectric ...

The superior colliculus is a midbrain region that is traditionally thought to help animals orient themselves toward important locations in space, like directing their eyes and head toward a bright flash of light. New research from the University of Chicago shows that this part of the brain also plays a role in complex cognitive tasks like visual categorization and decision making. In the new study, published in Nature Neuroscience, scientists measured the information contained in patterns of brain cell activity across multiple brain regions involved in visual category decisions. The researchers monitored activity in the superior colliculus (SC) and part of the posterior parietal ...

Lavas from hotspots—whether erupting in Hawaii, Samoa or Iceland—likely originate from a worldwide, uniform reservoir in Earth’s mantle, according to an evaluation of volcanic hotspots published today in Nature Geoscience. The findings indicate Earth’s mantle is far more chemically homogenous than scientists previously thought—and that lavas only acquire their unique chemical “flavours” enroute to the surface. “The discovery literally turns our view of hotspot lavas and the mantle upside down,” said Dr. Matthijs Smit, associate professor ...

The Amazon, often called the "lungs of the planet", is the world’s largest tropical forest, playing a crucial role in the global climate system due to its vast carbon storage. While it is typically warm and humid all year round, continued climate change poses the threat of more frequent and severe droughts and heat extremes. A new study, published in Nature Communications delves into future projections of the Amazon carbon cycle, focusing specifically on the impacts driven by climate change. Scientists use the latest generation of Earth system models from the Coupled Model Intercomparison Project which contributed to ...

A new way of making ammonia by harnessing the unique power of liquid metal could lead to significant cuts in carbon emissions caused by production of the widely-used chemical.   Ammonia is used in fertiliser to grow much of our food, but also plays a role in clean energy as a carrier to safely transport hydrogen. The global production of ammonia, however, comes at a high environmental cost: it consumes over 2% of global energy and produces up to 2% of global carbon emissions. RMIT Research Fellow and study ...

Researchers have uncovered a fascinating mechanism behind the reduction and asymmetry of emu wing bones. The wings not only show significant shortening, but the skeletal elements also fuse asymmetrically, a phenomenon traced back to the absence of muscle formation in the distal regions of the wings. During development, this lack of muscle leads to insufficient mechanical stress, which is crucial for proper bone formation. The team identified muscle progenitor cells with a unique dual identity, combining characteristics of both somite１-derived myogenic and lateral plate mesoderm2 cells. These ...

Only about ten percent of the world’s roughly 4,000 snake species have venom strong enough to seriously hurt a human, but that’s enough for snake bites to be an important public health concern. To help better understand how snakes make their venom and how venoms differ from one species to another, researchers developed a new way to zero in on the genes that snakes use in venom production. Their work was published in the journal Molecular Ecology Resources. “We’ve developed a tool that can tell us which venom-producing genes are present across an entire snake family in one fell swoop,” says Sara Ruane, the Assistant Curator of Herpetology in the ...

With the color additive, rooms ...

In the last decade, auxiliary information has been widely used to address data sparsity. Due to the advantages of feature extraction and the no-label requirement, autoencoder-based methods addressing auxiliary information have become quite popular. However, most existing autoencoder-based methods discard the reconstruction of auxiliary information, which poses a huge challenge for better representation learning and model scalability. To solve the problems, a research team led by Zhu YI published their new research on 15 August 2024 in Frontiers of Computer Science co-published by Higher Education Press and Springer Nature. The team proposed a novel representation ...

Cucumber is a common vegetable on people’s table because of its crisp and refreshing characteristics. In order to meet the market demand throughout the year, cucumber is now mainly planted in facility greenhouses. However, the loss of soil nutrients and the accumulation of pathogenic microorganisms are inevitable in successive years of cultivation. Cucumber corynespora leaf spot, also known as cucumber target spot disease, is a major foliar disease that causes cucumber yield reduction, and its pathogen is the Corynespora cassiicola. The pathogen harms cucumber leaves, causing irregular spots and affecting the photosynthesis ...

Globally, more than 13,000 plant species, equivalent to the entire native flora of Europe, have been naturalized outside their native ranges. A recent study, jointly conducted by scientists from China and the USA, has provided new insights about biodiversity, exotic invasion, and their relationship to climate change. Published in Nature Plants, the research uncovers the climatic niche mechanisms that shape both the vulnerability of native ecosystems and the invasiveness of exotic species in a warming world. A long-standing debate exists over the impact of exotic species on native ecosystems and ...

The Arctic frequently experiences temperatures that support the formation of mixed-phase clouds that contain supercooled liquid droplets and ice crystals. The composition of such clouds plays a crucial role in the region's energy balance and climate system. Clouds with more liquid last longer and reflect more sunlight than those with more ice crystals. With Arctic warming, meteorologists have been interested in determining the effect of rising temperatures on cloud composition and its broader effect on the region. Climate models generally predict that as the Arctic warms, clouds in the region will ...

A researcher from the University of Southampton (UK) has found evidence that the treeless, rugged, grassland landscape of the Falkland Islands was home to a lush, diverse rainforest up to 30 million years ago. A study by Dr Zoë Thomas, leading an international team of scientists, reveals that the South Atlantic archipelago was once covered in cool, wet woodland – similar to the present day rainforests found in Tierra del Fuego, off the tip of South America. The scientists conducted the research after clues to the whereabouts of buried remains of the ancient forest reached them via word-of-mouth in the tight knit community of Port Stanley, the Falklands’ ...
