Published Cheese of the future: Consumers open to animal-free alternatives
(via sciencedaily.com) Original source Companies and institutes are currently working on biotechnological processes for the production of 'dairy products' without the use of cows: In so-called precision fermentation, egg and milk proteins are produced with the help of bacteria, yeasts or other fungi. This results in foods such as milk or cheese with a familiar flavor and texture. Supporters hope that this will lead to more sustainable food production, as nutrient-rich proteins can be produced using fewer resources. But will consumers accept such products?
Published Talking about regeneration
(via sciencedaily.com) Original source Researchers transferred genes from simple organisms capable of regenerating their bodies into common fruit flies, more complex animals that cannot. They found the transferred gene suppressed an age-related intestinal issue in the flies. Their results suggest studying genes specific to animals with high regenerative capability may uncover new mechanisms for rejuvenating stem cell function and extending the healthy lifespan of unrelated organisms.
Published Warming stops tiny organisms working together
(via sciencedaily.com) Original source Hotter conditions prevent two tiny organisms working together for mutual benefit, new research shows.
Published The next generation of RNA chips
(via sciencedaily.com) Original source An international research team has succeeded in developing a new version of RNA building blocks with higher chemical reactivity and photosensitivity. This can significantly reduce the production time of RNA chips used in biotechnological and medical research. The chemical synthesis of these chips is now twice as fast and seven times more efficient.
Published Nasal COVID-19 vaccine halts transmission, animal study finds
(via sciencedaily.com) Original source A nasal COVID-19 vaccine blocks transmission of the virus, according to an animal study. The findings suggest that vaccines delivered directly to the nose or mouth could play a critical role in containing the spread of respiratory infections.
Published AI opens door to safe, effective new antibiotics to combat resistant bacteria
(via sciencedaily.com) Original source In a hopeful sign for demand for more safe, effective antibiotics for humans, researchers have leveraged artificial intelligence to develop a new drug that already is showing promise in animal trials.
Published New principle for treating tuberculosis
(via sciencedaily.com) Original source Researchers have succeeded in identifying and synthesizing a group of molecules that can act against the cause of tuberculosis in a new way. They describe that the so-called callyaerins act against the infectious disease by employing a fundamentally different mechanism compared to antibiotic agents used to date.
Published Scientists capture immune cells hidden in nasal passages
(via sciencedaily.com) Original source Scientists uncover 'striking' immune cell populations poised to fight SARS-CoV-2 in upper airway.
Published Gut microbes implicated in bladder cancer
(via sciencedaily.com) Original source Bladder cancer is the tenth most common type of cancer worldwide and is often linked to exposure to harmful chemicals, such as those found in tobacco smoke. A new study shows that the bacteria in our guts may play an important role in bladder cancer development. The scientists showed experimentally that certain gut bacteria can transform a class of carcinogens, often found in cigarette smoke, into related chemicals that accumulate in the bladder and give rise to tumors.
Published Bright prospects for engineering quantum light
(via sciencedaily.com) Original source Computers benefit greatly from being connected to the internet, so we might ask: What good is a quantum computer without a quantum internet?
Published Scientists discover entirely new wood type that could be highly efficient at carbon storage
(via sciencedaily.com) Original source Researchers undertaking an evolutionary survey of the microscopic structure of wood from some of the world's most iconic trees and shrubs have discovered an entirely new type of wood.
Published Researchers develop general framework for designing quantum sensors
(via sciencedaily.com) Original source Researchers have designed a protocol for harnessing the power of quantum sensors. The protocol could give sensor designers the ability to fine-tune quantum systems to sense signals of interest, creating sensors that are vastly more sensitive than traditional sensors.
Published Injury dressings in first-aid kits provide a new technique to reveal shark species after bite incidents
(via sciencedaily.com) Original source Scientists have revealed that injury dressings found in first-aid kits can reliably be used to identify shark species involved in bite incidents by deploying medical gauze to gather DNA samples from aquatic equipment, such as surfboards.
Published Precise genetics: New CRISPR method enables efficient DNA modification
(via sciencedaily.com) Original source A research group has developed a new method that further improves the existing CRISPR/Cas technologies: it allows a more precise and seamless introduction of tags into proteins at the gene level. This technology could significantly improve research on proteins in living organisms and opens up new possibilities for medical research.
Published What shapes a virus's pandemic potential? SARS-CoV-2 relatives yield clues
(via sciencedaily.com) Original source Two of the closest known relatives to SARS-CoV-2 -- a pair of bat coronaviruses discovered by researchers in Laos -- may transmit poorly in people despite being genetically similar to the COVID-19-causing virus, a new study reveals. The findings provide clues as to why some viruses have greater 'pandemic potential' than others and how researchers might go about identifying those that do before they become widespread.
Published Platypus and chicken reveal how chromosomes balance between the sexes
(via sciencedaily.com) Original source Geneticists uncover new insights into how sex chromosome systems work in the platypus and the chicken -- which will lead to better understandings of our own sex chromosome evolution and gene regulation.
Published How researchers turn bacteria into cellulose-producing mini-factories
(via sciencedaily.com) Original source Researchers have modified certain bacteria with UV light so that they produce more cellulose. The basis for this is a new approach with which the researchers generate thousands of bacterial variants and select those that have developed into the most productive.
Published MicroRNA study sets stage for crop improvements
(via sciencedaily.com) Original source MicroRNAs can make plants more capable of withstanding drought, salinity, pathogens and more. However, in a recent study scientists showed just how much we didn't know about the intricate processes plants use to produce them.
Published Winter breeding offers lifeline for monarch butterflies in Northern California
(via sciencedaily.com) Original source Monarch butterflies in Northern California are adapting to a changing climate by embracing an unexpected strategy: breeding in the winter. The shift could be key to the survival of the iconic insect, according to a new study.
Published Fetal brain impacted when mom fights severe flu: New mouse study explains how
(via sciencedaily.com) Original source New research using live mouse-adapted influenza virus improves upon previous mouse experiments to explain how maternal infection impacts fetal brain development. The study also indicates fetal brain changes are more likely once the severity of the mother's infection meets a specific threshold.
