GeneMAP discovery platform will help define functions for 'orphan' metabolic proteins      (via sciencedaily.com)     Original source 

Researchers have developed a discovery platform to probe the function of genes involved in metabolism -- the sum of all life-sustaining chemical reactions. The investigators used the new platform, called GeneMAP (Gene-Metabolite Association Prediction), to identify a gene necessary for mitochondrial choline transport.

How dust pollution from shrinking Great Salt Lake affects communities disproportionately      (via sciencedaily.com)     Original source 

Exposure to wind-blown dust from exposed playa of the Utah lake is worse in Hispanic neighborhoods, according to new research. Findings suggest restoring the lake could ease social inequities associated with air pollution.

Cool roofs are best at beating cities' heat      (via sciencedaily.com)     Original source 

Painting roofs white or covering them with a reflective coating would be more effective at cooling cities like London than vegetation-covered 'green roofs,' street-level vegetation or solar panels, finds a new study led by UCL researchers.

Early-onset El NiƱo means warmer winters in East Asia, and vice versa      (via sciencedaily.com)     Original source 

Researchers have found that the early onset of El Nino around June leads to warm winter climates in Japan, while the late onset of El Nino is associated with colder winters. By analyzing 100-ensemble member climate simulations over the past 61 years, the team found that the warming of the tropical Indian Ocean was a player in warmer Japanese winters.

A new breakthrough in understanding regeneration in a marine worm      (via sciencedaily.com)     Original source 

The sea worm Platynereis dumerilii is only a few centimeters long but has a remarkable ability: in just a few days, it can regenerate entire parts of its body after an injury or amputation. By focusing more specifically on the mechanisms at play in the regeneration of this worm's tail, a research team has observed that gut cells play a role in the regeneration of the intestine as well as other tissues such as muscle and epidermis.

Research shows how RNA 'junk' controls our genes      (via sciencedaily.com)     Original source 

Researchers have made a significant advance in understanding how genes are controlled in living organisms. The new study focuses on critical snippets of RNA in the tiny, transparent roundworm Caenorhabditis elegans (C. elegans). The study provides a detailed map of the 3'UTR regions of RNA in C. elegans. 3'UTRs (untranslated regions) are segments of RNA involved in gene regulation.

Proteins and fats can drive insulin production for some, paving way for tailored nutrition      (via sciencedaily.com)     Original source 

When it comes to managing blood sugar levels, most people think about counting carbs. But new research shows that, for some, it may be just as important to consider the proteins and fats in their diet. The study is the first large-scale comparison of how different people produce insulin in response to each of the three macronutrients: carbohydrates (glucose), proteins (amino acids) and fats (fatty acids). The findings reveal that production of the blood sugar-regulating hormone is much more dynamic and individualized than previously thought, while showing for the first time a subset of the population who are hyper-responsive to fatty foods.

Layers of carbonate provide insight into the world of the ancient Romans      (via sciencedaily.com)     Original source 

Archaeologists face a major challenge when they intend to acquire information about buildings or facilities of which only ruins remain. This was a particular challenge for the remnants of the Roman water mills in Barbegal in Southern France, dating back to the 2nd century CE. This unique industrial complex consisted of 16 water wheels placed in parallel rows. Little could at first be deduced about the site from these now scant ruins -- except that the wheels were supplied by an aqueduct that brought water from the surrounding hills. Researchers have now unraveled the history of the mill complex using calcium carbonate deposits that are now stored in the Archaeological Museum of Arles. These deposits had formed towards the end of the roughly 100-year operational life of the Barbegal water mills on the sides and base of the wooden supply system that conveyed the water to the wheels.

Degradation of cell wall key in the spread of antibiotic resistance      (via sciencedaily.com)     Original source 

A study provides new clues in the understanding of how antibiotic resistance spreads. The study shows how an enzyme breaks down the bacteria's protective outer layer, the cell wall, and thus facilitates the transfer of genes for resistance to antibiotics.

Researchers thwart resistant bacteria's strategy      (via sciencedaily.com)     Original source 

Bacteria are experts at evolving resistance to antibiotics. One resistance strategy is to cover their cell walls in sticky and gooey biofilm that antibiotics cannot penetrate. A new discovery could put a stop to this strategy.

Novel spectroscopy technique sheds light on NOx reduction      (via sciencedaily.com)     Original source 

The process that can convert pollution into benign by-products is called selective catalytic reduction, or SCR. Until now, it has been unclear how this reaction actually occurs, and contradictions have long existed between reaction models within the literature. Catalysis researchers used a technology called modulation excitation spectroscopy, or MES, to finally identify the correct pathway.

Investigating newly discovered hydrothermal vents at depths of 3,000 meters off Svalbard      (via sciencedaily.com)     Original source 

Hydrothermal vents can be found around the world at the junctions of drifting tectonic plates. But there are many hydrothermal fields still to be discovered. During a 2022 expedition of the MARIA S. MERIAN, the first field of hydrothermal vents on the 500-kilometer-long Knipovich Ridge off the coast of Svalbard was discovered.

Drowning in waste: Pollution hotspots in aquatic environments      (via sciencedaily.com)     Original source 

A new study explores waste management systems and reveals that achieving zero waste leakage by 2030 is unlikely, potentially jeopardizing related Sustainable Development Goals. The authors emphasize the need for global cooperation, particularly across four regions, to responsibly manage waste disposal.

Climate change to shift tropical rains northward      (via sciencedaily.com)     Original source 

Atmospheric scientists predict that unchecked carbon emissions will force tropical rains to shift northward in the coming decades, which would profoundly impact agriculture and economies near the Earth's equator. The northward rain shift would be spurred by carbon emissions that influence the formation of the intertropical convergence zones that are essentially atmospheric engines that drive about a third of the world's precipitation.

Antarctic ice shelves hold twice as much meltwater as previously thought      (via sciencedaily.com)     Original source 

Slush -- water-soaked snow -- makes up more than half of all meltwater on the Antarctic ice shelves during the height of summer, yet is poorly accounted for in regional climate models. The findings could have profound implications for ice shelf stability and sea level rise.
