Published Where do our limbs come from?
(via sciencedaily.com) Original source Scientists have uncovered new clues about the origin of paired appendages -- a major evolutionary step that remains unresolved and highly debated.
Published Move over, armadillos: There's a new bone-plated mammal in town
(via sciencedaily.com) Original source Armadillos have long been considered to be the only living mammals that produce protective bony plates. But a new study unexpectedly shows that African spiny mice produce the same structures beneath the skin of their tails, which until now had gone largely undetected.
Published A look into the heart of cellular waste disposal
(via sciencedaily.com) Original source Researchers reveal how a nanomachine takes care of cleaning up inside the cell.
Published Breakthrough in computer chip energy efficiency could cut data center electricity use
(via sciencedaily.com) Original source Researchers have made a breakthrough toward reducing the energy consumption of the photonic chips used in data centers and supercomputers.
Published Engineers create bacteria that can synthesize an unnatural amino acid
(via sciencedaily.com) Original source Researchers have engineered bacteria to synthesize an amino acid that contains a rare functional group that others have shown to have implications in the regulation of our immune system. The researchers also taught a single bacterial strain to create the amino acid and place it at specific sites within target proteins. These findings provide a foundation for developing unique vaccines and immunotherapies in the future.
Published Calcium rechargeable battery with long cycle life
(via sciencedaily.com) Original source With the use of electric vehicles and grid-scale energy storage systems on the rise, the need to explore alternatives to lithium-ion batteries has never been greater. Researchers have recently developed a prototype calcium metal rechargeable battery capable of 500 cycles of repeated charge-discharge -- the benchmark for practical use. The breakthrough was made thanks to the development of a copper sulfide nanoparticle/carbon composite cathode and a hydride-based electrolyte.
Published Researchers examine cooling power plants with brackish groundwater
(via sciencedaily.com) Original source Nontraditional water sources can be deployed to help cope with climate-induced water risks and tackle the increasing water demand for decarbonization of fossil fuel-fired power plants, but that could increase the cost of electricity generation by 8 percent to 10 percent.
Published Previous smallpox vaccine provides immunity to mpox
(via sciencedaily.com) Original source Vaccines against smallpox given until the mid-1970s offer continuing cross-reactive immunity to mpox (previously known as monkeypox), researchers report.
Published Researchers find new mechanism for sodium salt detoxification in plants
(via sciencedaily.com) Original source A team of researchers has found a mechanism in thale cress (Arabidopsis thaliana) which enables plants to provide protection against salt stress for their sensitive stem cells in the meristem at the root tip.
Published Effects of crypto mining on Texas power grid
(via sciencedaily.com) Original source Scientists are working to understand how cryptocurrency mining impacts the power grid and how to use this information for further research, education and policymaking.
Published Study may explain why high-sugar diets can worsen IBD
(via sciencedaily.com) Original source Excess sugar hampers cells that renew the colon's lining in a mouse model of inflammatory bowel disease (IBD), according to a new study that could help get to the bottom of why limiting sugary foods can ease symptoms for patients with IBD.
Published What you count is not necessarily what counts
(via sciencedaily.com) Original source Seawater is full of bacteria, hundreds of thousands live in every liter. But the sheer number of bacteria living in the water does not necessarily mean a lot. More important is how active they are and how quickly they duplicate.
Published A multiomics approach provides insights into flu severity
(via sciencedaily.com) Original source Researchers were able to identify changes in the accessibility (that is, the 'readability') of transposable elements. To do this, the researchers used an approach combining various sets of multiomics data, which characterize and quantify collections of biomolecules in cells or organisms. One was the transcriptome, which consists of all copies of RNA transcribed from DNA in the cell. The other was the epigenome, which is the collection of chemical changes to DNA that modify gene expression. An advantage of this multiomics approach is that they were able to identify families of transposable elements with changes in accessibility, which would have likely been missed by previous approaches.
Published Fine particulate matter catalyzes oxidative stress in the lungs
(via sciencedaily.com) Original source Study sheds new light on the adverse health effects of air pollution: hydrogen peroxide production of fine particles may not be as important as previously assumed. A new study reveals that the adverse health effects of fine particulate matter (PM2.5) are attributable to the conversion of peroxides into more reactive species such as the hydroxyl radical (OH) rather than the direct chemical production of hydrogen peroxide (H2O2) as previously thought.
Published Designing synthetic receptors for precise cell control
(via sciencedaily.com) Original source Scientists have developed a groundbreaking new technique for engineering biosensors that respond sensitively to specific biomolecules, enhancing cell migration and targeting in cancer treatment. The findings could lead to more precise control over cellular processes for a wide range of therapeutic applications.
Published Under control to the very end -- how our cells kill themselves
(via sciencedaily.com) Original source Every day, millions of cells die in our body. Other than generally assumed, cells do not simply burst at the end of their lives but rather, a specific protein serves as a breaking point for cell membrane rupture. Researchers have now been able to elucidate the exact mechanism at the atomic level.
Published A guide through the genome
(via sciencedaily.com) Original source Plants show enormous variety in traits relevant to breeding, such as plant height, yield and resistance to pests. One of the greatest challenges in modern plant research is to identify the differences in genetic information that are responsible for this variation.
Published How plants use sugar to produce roots
(via sciencedaily.com) Original source Along with sugar reallocation, a basic molecular mechanism within plants controls the formation of new lateral roots. Botanists have demonstrated that it is based on the activity of a certain factor, the target of rapamycin (TOR) protein. A better understanding of the processes that regulate root branching at the molecular level could contribute to improving plant growth and therefore crop yields, according to the research team leader.
Published Communities should reconsider walking away from curbside recycling, study shows
(via sciencedaily.com) Original source Researchers took a deep dive into the economic and environmental value of community recycling efforts and compared it to the value of other climate change mitigation practices, concluding it provides a return on investment.
Published Corals mark friendly algae for ingestion -- revealing possible conservation target
(via sciencedaily.com) Original source Biologists reveals how coral cells tag friendly algae before ingesting them, initiating a mutually beneficial relationship. This information could guide next-level coral conservation efforts.
