Published How to eat our way out of the climate crisis
(via sciencedaily.com)
Original source 
Researchers conducted a study to determine if replacing dietary fats from palm oil, soy and other agricultural crops with fats created synthetically in chemical or biological processes could help reduce climate change-causing greenhouse gases. The researchers' analysis finds a reduction in carbon emissions and other benefits, such the opening of agricultural lands to reforestation which benefits biodiversity and creates a carbon sink.
Published Keeping an eye on the regions when it comes to climate change
(via sciencedaily.com)
Original source 
Up to now, the results of climate simulations have sometimes contradicted the analysis of climate traces from the past. Physicists and climatologists have now brought together experts in climate models and climate tracks to clarify how the discrepancies come about. The surprising result has now been published: in a way, both sides are right. Climate models correctly simulate global temperature trends, but often underestimate the strength of regional climate fluctuations, especially over the course of decades to centuries.
Published Decarbonizing light-duty transportation in the United States: Study reveals strategies to achieve goal
(via sciencedaily.com)
Original source 
Researchers found that meeting greenhouse gas emissions goals for light-duty vehicles, which are passenger vehicles such as cars and trucks, is possible, but not just by increasing electric vehicle sales.
Published How salt from the Caribbean affects our climate
(via sciencedaily.com)
Original source 
Past cold periods such as the Little Ice Age were associated with reduced strength of North Atlantic currents and increased surface salinity in the Caribbean. This was accompanied by disturbances in the distribution of salt to the north leading to longer, stronger cooling phases in the northern hemisphere.
Published Some benefits of exercise stem from the immune system
(via sciencedaily.com)
Original source 
Research in mice shows that the anti-inflammatory properties of exercise may arise from immune cells mobilized to counter exercise-induced inflammation. Immune cells prevent muscle damage by lowering levels of interferon, a key driver of chronic inflammation, inflammatory diseases, and aging.
Published Seeing the unseen: How butterflies can help scientists detect cancer
(via sciencedaily.com)
Original source 
There are many creatures on our planet with more advanced senses than humans. Turtles can sense Earth's magnetic field. Mantis shrimp can detect polarized light. Elephants can hear much lower frequencies than humans can. Butterflies can perceive a broader range of colors, including ultraviolet (UV) light.
Published Milestone moment toward development of nuclear clock
(via sciencedaily.com)
Original source 
Physicists have started the countdown on developing a new generation of timepieces capable of shattering records by providing accuracy of up to one second in 300 billion years, or about 22 times the age of the universe.
Published Scientists map loss of groundwater storage around the world
(via sciencedaily.com)
Original source 
Global water resources are stretched by climate change and human population growth, and farms and cities are increasingly turning to groundwater to fill their needs. Unfortunately, the pumping of groundwater can cause the ground surface above to sink, as the aquifers below are drained and the architecture of the ground collapses. A new study maps this loss of groundwater storage capacity around the world.
Published New approach to water electrolysis for green hydrogen
(via sciencedaily.com)
Original source 
Scientists have pioneered a novel approach to water electrolysis catalysts for green hydrogen production.
Published Photo battery achieves competitive voltage
(via sciencedaily.com)
Original source 
Researchers have developed a monolithically integrated photo battery using organic materials. The photo battery achieves an unprecedented high discharge potential of 3.6 volts. The system is capable of powering miniature devices.
Published Vacuum in optical cavity can change material's magnetic state without laser excitation
(via sciencedaily.com)
Original source 
Researchers in Germany and the USA have produced the first theoretical demonstration that the magnetic state of an atomically thin material, ?-RuCl3, can be controlled solely by placing it into an optical cavity. Crucially, the cavity vacuum fluctuations alone are sufficient to change the material's magnetic order from a zigzag antiferromagnet into a ferromagnet.
Published Charged 'molecular beasts' the basis for new compounds
(via sciencedaily.com)
Original source 
Mass spectrometers are high-tech machines that play an important role in our society. They are highly sensitive analytical instruments that are indispensable in areas such as medical diagnostics, food quality control and the detection of hazardous chemical substances. A research group is working to modify mass spectrometers so that they can be used for a completely different purpose: the chemical synthesis of new molecules.
Published An exotic tick that can kill cattle is spreading across Ohio
(via sciencedaily.com)
Original source 
A species of exotic tick arrived in Ohio in 2021 in such huge numbers that their feeding frenzy on a southeastern farm left three cattle dead of what researchers believe was severe blood loss. The scientists have reported on the state's first known established population of Asian longhorned ticks, and are now conducting research focused on monitoring and managing these pests.
Published Large herbivores such as elephants, bison and moose contribute to tree diversity
(via sciencedaily.com)
Original source 
Using global satellite data, a research team has mapped the tree cover of the world's protected areas. The study shows that regions with abundant large herbivores in many settings have a more variable tree cover, which is expected to benefit biodiversity overall.
Published The kids aren't alright: Saplings reveal how changing climate may undermine forests
(via sciencedaily.com)
Original source 
Researchers studied how young trees respond to a hotter, drier climate. Their findings can help shape forest management policy and our understanding of how landscapes will change.
Published Predicting saltwater intrusion into groundwater using Plymouth, Mass. as test case
(via sciencedaily.com)
Original source 
As the world warms and ice sheets melt, the ocean continually rises. The greater Boston area can expect to see between one and six feet of sea level rise by 2100, according to recent estimates. To find out what this rise might mean for freshwater supplies, a team of hydrogeologists developed an innovative new model that can not only predict saltwater intrusion over the next 75 years, but also pinpoint the main sources of salt contamination today -- road salt and human development.
Published Viral impostors: Breakthrough for virus research
(via sciencedaily.com)
Original source 
The penetration of viruses into cells can now be tracked with unprecedented accuracy thanks to an innovative design for pseudoviruses.
Published New secrets about cat evolution revealed
(via sciencedaily.com)
Original source 
By comparing genomes of several cat species, the project has helped researchers understand why cat genomes tend to have fewer complex genetic variations (such as rearrangements of DNA segments) than other mammal groups, like primates. It also revealed new insights into which parts of cat DNA are most likely to evolve rapidly and how they play a role in species differentiation.
Published New antibiotic approach proves promising against lyme bacterium
(via sciencedaily.com)
Original source 
Using a technique that has shown promise in targeting cancer tumors, a team has found a way to deploy a molecular warhead that can annihilate the bacterium that causes Lyme disease.
Published Visualizing fungal infections deep in living host tissue reveals proline metabolism facilitates virulence
(via sciencedaily.com)
Original source 
Scientists have published the first successful application of 2-photon intravital microscopy (IVM) to image the dynamics of fungal infections in the kidney of a living host. The study reveals that the opportunistic human fungal pathogen Candida albicans requires the ability to metabolize proline, an amino acid obtained from the host, to mount virulent infections.
