Published Atlas of proteins reveals inner workings of cells
(via sciencedaily.com) Original source Researchers discover how proteins behave inside cells using AI, which has the potential to guide drug design.
Published Not so simple: Mosses and ferns offer new hope for crop protection
(via sciencedaily.com) Original source Mosses, liverworts, ferns and algae may offer an exciting new research frontier in the global challenge of protecting crops from the threat of disease.
Published Big gain in battle against harmful bacteria
(via sciencedaily.com) Original source An unexpected find has enabled important progress to be made in the battle against harmful bacteria.
Published Tackling the challenge of coca plant ID: Wild vs cultivated for cocaine
(via sciencedaily.com) Original source A new paper reveals that it's not as straightforward as it might seem. Despite decades of data collection by the United Nations Office on Drugs and Crime (UNODC), which has been valuable to monitor changes in areas occupied by illegal coca plantations in South America, there is no reliable scientific method to distinguish between different types of coca plants.
Published Archaeologists report earliest evidence for plant farming in east Africa
(via sciencedaily.com) Original source A trove of ancient plant remains excavated in Kenya helps explain the history of plant farming in equatorial eastern Africa, a region long thought to be important for early farming but where scant evidence from actual physical crops has been previously uncovered.
Published Study examines tree adaptability to climate change
(via sciencedaily.com) Original source Many trees could expand their ranges by more than 25 percent based on their potential temperature tolerances.
Published New one-step method to make multiple edits to a cell's genome
(via sciencedaily.com) Original source A team of scientists have developed a new method that enables them to make precise edits in multiple locations within a cell -- all at once. Using molecules called retrons, they created a tool that can efficiently modify DNA in bacteria, yeast, and human cells.
Published First local extinction in the US due to sea level rise, study suggests
(via sciencedaily.com) Original source The United States has lost its only stand of the massive Key Largo tree cactus in what researchers believe is the first local extinction of a species caused by sea level rise in the country.
Published How a plant app helps identify the consequences of climate change
(via sciencedaily.com) Original source A research team has developed an algorithm that analyses observational data from a plant identification app. The novel approach can be used to derive ecological patterns that could provide valuable information about the effects of climate change on plants.
Published New bio-based tool quickly detects concerning coronavirus variants
(via sciencedaily.com) Original source Researchers have developed a bioelectric device that can detect and classify new variants of coronavirus to identify those that are most harmful. It has the potential to do the same with other viruses, as well.
Published 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.
Published Wastewater is a viable medium for growing lettuce in hydroponic systems
(via sciencedaily.com) Original source Urban agriculture has the potential to improve food security through local, efficient, and sustainable food production. Examples of urban food systems include hydroponics, where plants grow in a nutrient solution without soil, and aquaponics, which combines hydroponics with raising fish in tanks. A new study examines the use of aquaponics wastewater as a growth medium for lettuce in a hydroponic system. This practice can potentially create a circular ecosystem for organic waste recycling and food production.
Published Never-before-seen view of gene transcription captured
(via sciencedaily.com) Original source New tech reveals findings that address long-standing theories about how bacteria begin the process of making RNA from DNA.
Published Do genes-in-pieces code for proteins that fold in pieces?
(via sciencedaily.com) Original source A new study offers new insights into the evolution of foldable proteins.
Published Researchers uncover key mechanisms in chromosome structure development
(via sciencedaily.com) Original source Researchers are making strides in understanding how chromosome structures change throughout the cell's life cycle.
Published Climate change drives tree species towards colder, wetter regions
(via sciencedaily.com) Original source Climate change is likely to drive tree species towards colder and wetter regions.
Published Mechanism of bio-inspired control of liquid flow
(via sciencedaily.com) Original source The more we discover about the natural world, the more we find that nature is the greatest engineer. Past research implied that liquids can only be transported in fixed direction on species with specific liquid communication properties and cannot switch the transport direction. Recently, researchers have shown that an African plant controls water movement in a previously unknown way -- and this could inspire breakthroughs in a range of technologies in fluid dynamics and nature-inspired materials, including applications that require multistep and repeated reactions, such as microassays, medical diagnosis and solar desalination etc.
Published 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.
Published 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.
Published 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.
