Published Key genes linked to DNA damage and human disease uncovered
(via sciencedaily.com) Original source Scientists unveil 145 genes vital for genome health, and possible strategies to curb progression of human genomic disorders.
Published Cleaned surfaces may be germ-free, but they're not bare
(via sciencedaily.com) Original source Since the outbreak of COVID-19, surfaces in public spaces are cleaned more often. While disinfectant solutions eliminate germs, they don't leave behind a truly bare surface. They deposit a thin film that doesn't get wiped up, even after giving the surface a good polish. In a new study, researchers show that residues left by commercial cleaning products contain a wider range of compounds that could impact indoor air quality than previously thought.
Published Researchers uncover mechanisms behind enigmatic shapes of nuclei
(via sciencedaily.com) Original source White blood cells known as neutrophils feature a nucleus that is structured strikingly different than most nuclei. These unique shapes permit neutrophils to travel all over the body to combat invading pathogens. Scientists have now deciphered the shapeshifting puzzle of the neutrophil nucleus.
Published Tawny owl's pale grey color linked to vital functions ensuring survival in extreme conditions
(via sciencedaily.com) Original source A recent genetic discovery has revealed that the pale grey plumage of the tawny owl is linked to crucial functions that aid the bird's survival in cold environments. As global temperatures rise, dark brown plumage is likely to become more common in tawny owls living in colder areas.
Published Microscopy: Overcoming the traditional resolution limit for the fast co-tracking of molecules
(via sciencedaily.com) Original source Researchers have developed an innovative method to simultaneously track rapid dynamic processes of multiple molecules at the molecular scale.
Published Cold-water coral traps itself on mountains in the deep sea
(via sciencedaily.com) Original source Corals searching for food in the cold and dark waters of the deep sea are building higher and higher mountains to get closer to the source of their food. But in doing so, they may find themselves trapped when the climate changes.
Published Pesticides to help protect seeds can adversely affect earthworms' health
(via sciencedaily.com) Original source While pesticides protect crops from hungry animals, pesky insects, or even microbial infections, they also impact other vital organisms, including bees and earthworms. And today, research reveals that worms are affected by the relatively small amounts of chemicals that can leach out of pesticide-treated seeds. Exposure to nonlethal amounts of these insecticides and fungicides resulted in poor weight gain and mitochondrial DNA (mtDNA) damage in the worms.
Published Female lab mice behave very differently when placed outdoors
(via sciencedaily.com) Original source A new study has examined social behavior of lab mice in large outdoor enclosures.
Published By growing animal cells in rice grains, scientists dish up hybrid food
(via sciencedaily.com) Original source From lab-grown chicken to cricket-derived protein, these innovative alternatives offer hope for a planet struggling with the environmental and ethical impacts of industrial agriculture. Now, scientists add a new recipe to the list -- cultured beef rice -- by growing animal muscle and fat cells inside rice grains. The method results in a nutritious and flavorful hybrid food that, once commercialized, could offer a more affordable protein alternative with a smaller carbon footprint.
Published Is the Amazon forest approaching a tipping point?
(via sciencedaily.com) Original source Global warming may be interacting with regional rainfall and deforestation to accelerate forest loss in the Amazon, pushing it towards partial or total collapse. New research has identified the potential thresholds of these stressors, showing where their combined effects could produce a 'tipping point' -- in which the forest is so fragile that just a small disturbance could cause an abrupt shift in the state of the ecosystem.
Published Biomanufacturing using chemically synthesized sugars enables sustainable supply of sugar without competing with food
(via sciencedaily.com) Original source Researchers have succeeded in biomanufacturing from chemically synthesized sugar for the first time in the world. With refinement of this technology, one can envision a future society in which the sugar required for biomanufacturing can be obtained 'anytime, anywhere, and at high rate'. In the future, biomanufacturing using chemically synthesized sugar is expected to be a game changer in the biotechnology field -- including the production of biochemicals, biofuels, and food, where sugar is an essential raw material -- ultimately leading to the creation of a new bio-industry.
Published A century of reforestation helped keep the eastern US cool
(via sciencedaily.com) Original source Widespread 20th-century reforestation in the eastern United States helped counter rising temperatures due to climate change, according to new research. The authors highlight the potential of forests as regional climate adaptation tools, which are needed along with a decrease in carbon emissions.
Published Benefits of heat pumps
(via sciencedaily.com) Original source Millions of U.S. households would benefit from heat pumps, but the cost of installing the technology needs to come down to make their use a more attractive proposition.
Published CRISPR-copies: New tool accelerates and optimizes genome editing
(via sciencedaily.com) Original source Researchers are further improving CRISPR's versatility to engineer new grasses and yeasts for biochemical production.
Published Frequent marine heatwaves in the Arctic Ocean will be the norm
(via sciencedaily.com) Original source Marine heatwaves will become a regular occurrence in the Arctic in the near future and are a product of higher anthropogenic greenhouse-gas emissions -- as shown in a new study.
Published Greenland's ice sheet is melting -- and being replaced by vegetation
(via sciencedaily.com) Original source An estimated 11,000 sq miles or 28,707 sq kilometers of Greenland's ice sheet and glaciers have melted over the last three decades, according to a major analysis of historic satellite records.
Published Eco-friendly way to generate power from waste wood
(via sciencedaily.com) Original source A new study by researchers has revealed a sustainable method of efficiently converting waste heat into electricity using Irish wood products, while minimizing costs and environmental impact.
Published Low-cost microbe can speed biological discovery
(via sciencedaily.com) Original source Researchers have created a new version of a microbe to compete economically with E. coli -- a bacteria commonly used as a research tool due to its ability to synthesize proteins -- to conduct low-cost and scalable synthetic biological experiments.
Published If we can't untangle this mess, Norway's blue industry will never be green
(via sciencedaily.com) Original source For the first time, researchers have investigated how ropes and fishing lines are handled by the Norwegian commercial fishing industry. The fishing fleet loses almost 400 tons of rope in Norwegian waters every year.
Published New trial highlights incremental progress towards a cure for HIV-1
(via sciencedaily.com) Original source A new clinical trial suggests that a combination of the drug vorinostat and immunotherapy can coax HIV-infected cells out of latency and attack them. The findings highlight how close -- yet still far -- researchers have come to developing a cure for HIV-1.
