Published Nitrogen runoff strategies complicated by climate change
(via sciencedaily.com)
Original source 
As climate change progresses, rising temperatures may impact nitrogen runoff from land to lakes and streams more than projected increases in total and extreme precipitation for most of the continental United States, according to new research from a team of climate scientists.
Published The 'unknome': A database of human genes we know almost nothing about
(via sciencedaily.com)
Original source 
Researchers hope that a new, publicly available database they have created will shrink, not grow, over time. That's because it is a compendium of the thousands of understudied proteins encoded by genes in the human genome, whose existence is known but whose functions are mostly not.
Published Ancient DNA reveals an early African origin of Cattle in the Americas
(via sciencedaily.com)
Original source 
Using ancient DNA, researchers have determined cattle were imported from Africa to the Americas much earlier in the process of European colonization than documented. The first records of African cattle in the Americas date back to the 1800s, leading some historians to conclude that early colonists relied entirely on a small stock of European cattle initially shipped to the Caribbean Islands. DNA from archaeological specimens pushes the introduction of African cattle back by more than 100 years.
Published City-dwelling wildlife demonstrate 'urban trait syndrome'
(via sciencedaily.com) 
City life favors species that are adaptable and not too fussy about what they eat, among other characteristics. A worldwide consortium of scientists calls the resulting collection of traits an 'Urban Trait Syndrome.'
Published Quantum material exhibits 'non-local' behavior that mimics brain function
(via sciencedaily.com) 
New research shows that electrical stimuli passed between neighboring electrodes can also affect non-neighboring electrodes. Known as non-locality, this discovery is a crucial milestone toward creating brain-like computers with minimal energy requirements.
Published Managing domestic and wildcats is likely to remain fraught, new research warns
(via sciencedaily.com)
Original source 
Current efforts to protect and restore native biodiversity is being threatened by difficulties in identifying wild and domestic cats, and categorization is likely to remain fraught for the foreseeable future, experts have warned.
Published Whale-like filter-feeding discovered in prehistoric marine reptile
(via sciencedaily.com)
Original source 
A remarkable new fossil from China reveals for the first time that a group of reptiles were already using whale-like filter feeding 250 million years ago.
Published New Antarctic extremes 'virtually certain' as world warms
(via sciencedaily.com)
Original source 
Extreme events in Antarctica such as ocean heatwaves and ice loss will almost certainly become more common and more severe, researchers say.
Published Bat activity lower at solar farm sites
(via sciencedaily.com) 
The activity level of six bat species was significantly reduced at solar farm sites, researchers have observed.
Published New model reduces bias and enhances trust in AI decision-making and knowledge organization
(via sciencedaily.com) 
Researchers have developed a new explainable artificial intelligence (AI) model to reduce bias and enhance trust and accuracy in machine learning-generated decision-making and knowledge organization.
Published Remission from HIV-1 infection: Discovery of broadly neutralizing antibodies that contribute to virus control
(via sciencedaily.com)
Original source 
Some HIV-1 carriers who have received an early antiretroviral treatment during several years are able to control the virus for a long term after treatment interruption. However, the mechanisms enabling this post-treatment control have not been fully elucidated. Scientists have now investigated and revealed how neutralizing antibodies, including those described as broadly neutralizing, contribute to virus control. A clinical trial involving the use of broadly neutralizing antibodies should begin in France before the end of 2023.
Published Mineralization of bone matrix regulates tumor cell growth
(via sciencedaily.com)
Original source 
Tumor cells are known to be fickle sleeper agents, often lying dormant in distant tissues for years before reactivating and forming metastasis. Numerous factors have been studied to understand why the activation occurs, from cells and molecules to other components in the so-called tissue microenvironment.
Published Potential novel breakthrough treatment for fungal infections
(via sciencedaily.com)
Original source 
Fungal infections are killing thousands of Americans each year, some with a morbidity rate of nearly 80%. To make matters worse, only a handful of antifungal treatments are available, and even those are becoming less effective as fungi become more resistant. However, researchers recently published findings indicating that a novel breakthrough treatment may have been discovered.
Published Smart devices: Putting a premium on peace of mind
(via sciencedaily.com) 
The White House has announced plans to roll out voluntary labeling for internet-connected devices like thermostats and baby monitors that meet certain cybersecurity standards. A new survey of U.S. consumers shows that they are willing to pay a significant premium to tell which gadgets are safe from security attacks before they buy. But voluntary product labels may not be enough if the program is going to protect consumers in the long run, the findings suggest.
Published Uncovering the Auger-Meitner Effect's crucial role in electron energy loss
(via sciencedaily.com)
Original source 
Defects often limit the performance of devices such as light-emitting diodes (LEDs). The mechanisms by which defects annihilate charge carriers are well understood in materials that emit light at red or green wavelengths, but an explanation has been lacking for such loss in shorter-wavelength (blue or ultraviolet) emitters.
Published Carbon dioxide -- not water -- triggers explosive basaltic volcanoes
(via sciencedaily.com)
Original source 
Geoscientists have long thought that water -- along with shallow magma stored in Earth's crust -- drives volcanoes to erupt. Now, thanks to newly developed research tools, scientists have learned that gaseous carbon dioxide can trigger explosive eruptions.
Published Latest in body art? 'Tattoos' for individual cells
(via sciencedaily.com)
Original source 
Engineers have developed nanoscale tattoos -- dots and wires that adhere to live cells -- in a breakthrough that puts researchers one step closer to tracking the health of individual cells.
Published Current estimates of Lake Erie algae toxicity may miss the mark
(via sciencedaily.com)
Original source 
A new study analyzing toxins produced by Microcystis, the main type of cyanobacteria that compose the annual harmful algal bloom (HAB) in Lake Erie, suggests that the toxicity of the bloom may be overestimated in earlier warm months and underestimated later in the summer.
Published Butterflies can remember where things are over sizeable spaces
(via sciencedaily.com)
Original source 
Heliconius butterflies are capable of spatial learning, scientists have discovered. The results provide the first experimental evidence of spatial learning in any butterfly or moth species.
Published Self-supervised AI learns physics to reconstruct microscopic images from holograms
(via sciencedaily.com) 
Researchers have unveiled an artificial intelligence-based model for computational imaging and microscopy without training with experimental objects or real data. The team introduced a self-supervised AI model nicknamed GedankenNet that learns from physics laws and thought experiments. Informed only by the laws of physics that universally govern the propagation of electromagnetic waves in space, the researchers taught their AI model to reconstruct microscopic images using only random artificial holograms -- synthesized solely from 'imagination' without relying on any real-world experiments, actual sample resemblances or real data.
