Activity in brain system that controls eye movements highlights importance of spatial thinking
2024-09-19
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 ...
New research reenvisions Earth’s mantle as a relatively uniform reservoir
2024-09-19
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 ...
Global warming leads to drier and hotter Amazon: reducing uncertainty in future rainforest carbon loss
2024-09-19
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 ...
Low-carbon ammonia offers green alternative for agriculture and hydrogen transport
2024-09-19
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.

New mechanism uncovered for the reduction of emu wings
2024-09-19
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 ...
Zeroing in on the genes that snakes use to produce venom
2024-09-19
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 ...

Serial-autoencoder for personalized recommendation
2024-09-19
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 ...
How do look for microbes in nature that are beneficial to plant?
2024-09-19
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 ...

Arctic warming may fuel ice formation in clouds
2024-09-19
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 ...
Rugged Falklands landscape was once a lush rainforest
2024-09-19
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’ ...

Triptans more effective than newer, more expensive migraine drugs
2024-09-18
Some triptans are a more effective treatment for acute migraines than newer, more expensive drugs, finds an analysis of the latest evidence published by The BMJ today.
Triptans work by narrowing blood vessels in the brain and preventing the release of chemicals that cause pain and inflammation.
The findings show that four triptans - eletriptan, rizatriptan, sumatriptan, and zolmitriptan - were better at relieving migraine pain than the recently marketed and more expensive drugs lasmiditan, rimegepant, and ubrogepant, which were comparable to paracetamol ...
