Published Flower power on Indian farms helps bees and boosts livelihoods
(via sciencedaily.com) Original source Planting flowers beside food crops on farms in India attracts bees, boosts pollination and improves crop yield and quality, researchers have found.
Published Alcohol consumption may have positive and negative effects on cardiovascular disease risk
(via sciencedaily.com) Original source A new study found that alcohol consumption may have counteractive effects on CVD risk, depending on the biological presence of certain circulating metabolites -- molecules that are produced during or after a substance is metabolized and studied as biomarkers of many diseases. The researchers observed a total of 60 alcohol consumption-related metabolites, identifying seven circulating metabolites that link long-term moderate alcohol consumption with an increased risk of CVD, and three circulating metabolites that link this same drinking pattern with a lower risk of CVD.
Published Breathing highway air increases blood pressure
(via sciencedaily.com) Original source A new study found that unfiltered air from rush-hour traffic significantly increased passengers' blood pressure, both while in the car and up to 24 hours later.
Published Nano-sized cell particles are promising intervention tool in treating infectious diseases
(via sciencedaily.com) Original source Extracellular vesicles were found to inhibit the viral infection of COVID-19 and potentially other infectious diseases.
Published A spectrum of possibilities: Insights into the evolution of far-red light photosynthesis
(via sciencedaily.com) Original source Scientists have unraveled the evolutionary journey of a unique type of photosynthesis that allows some bacteria to harness far-red light, a region beyond the visible spectrum. This discovery could pave the way for engineering plants with enhanced light absorption capabilities and has implications for our search for extraterrestrial life.
Published Commitments needed to solve aviation's impact on our climate
(via sciencedaily.com) Original source Researchers could find no simple solution to limiting non-CO2 emissions from aircraft.
Published Scientists harness flower 'super power' to pave the way for new drug treatments
(via sciencedaily.com) Original source Researchers have developed a way of joining up the head and tail of a protein, making it more stable and easier to get into cells.
Published Solar activity likely to peak next year
(via sciencedaily.com) Original source Researchers have discovered a new relationship between the Sun's magnetic field and its sunspot cycle, that can help predict when the peak in solar activity will occur. Their work indicates that the maximum intensity of solar cycle 25, the ongoing sunspot cycle, is imminent and likely to occur within a year.
Published Minimalist or maximalist? The life of a microbe a mile underground
(via sciencedaily.com) Original source Researchers characterize nearly 600 microbial genomes collected from goldmine. The study illuminates 'microbial dark matter' residing below the surface. Microbes divide into two groups: minimalists that have one, specialized job or maximalists that are prepared to use any available resource. Study has implications for how underground activities, like mining and carbon storage, could affect or be affected by microbial life. The lifestyle of these 'intraterrestrial' microbes also provides hints to what organisms could be living on other planets.
Published Slash-and-burn agriculture can increase forest biodiversity, researchers find
(via sciencedaily.com) Original source The slash-and-burn agriculture practiced by many Indigenous societies across the world can actually have a positive impact on forests, according to a new study done in Belize. Researchers found that in areas of the rainforest in which Indigenous farmers using slash-and-burn techniques created intermediate-sized farm patches -- neither too small nor too large -- there were increases in forest plant diversity.
Published New material reduces bacterial infection and speeds up bone healing
(via sciencedaily.com) Original source Researchers have developed a new surgical implant that has the potential to transform the treatment of complex bone infections. When implanted on an injured or infected bone, the material can not only speed up bone healing, it also reduces the risk of infections without the need for traditional antibiotics.
Published Scientist discovers potential brain link between stress, emotional eating
(via sciencedaily.com) Original source Scientists describe how they identified a molecule that may trigger over-consumption of comfort foods after a threatening event.
Published Giant sea salt aerosols play major role in Hawai'i's coastal clouds, rain
(via sciencedaily.com) Original source A new study from atmospheric scientists revealed that the coastline can produce up to five times the concentration of giant sea salt aerosols compared to the open ocean and that coastal clouds may contain more of these particles than clouds over the open ocean -- affecting cloud formation and rain around the Hawaiian Islands.
Published Recycled phosphorus fertilizer reduces nutrient leaching, maintains yield
(via sciencedaily.com) Original source A promising new form of ammonium phosphate fertilizer has been field-tested. The fertilizer, struvite, offers a triple win for sustainability and crop production, as it recycles nutrients from wastewater streams, reduces leaching of phosphorus and nitrogen in agricultural soils, and maintains or improves soybean yield compared to conventional phosphorus fertilizers.
Published Scientists find both potential threats and promising resources in the thriving colonies of bacteria and fungi on ocean plastic trash
(via sciencedaily.com) Original source Scientists have found both potential threats and promising resources in the thriving colonies of bacteria and fungi on plastic trash washed up on shores.
Published Mixing heat with hair styling products may be bad for your health
(via sciencedaily.com) Original source Hair products often contain ingredients that easily evaporate, so users may inhale some of these chemicals, potentially posing health repercussions. Now, researchers have studied emissions of these volatile organic compounds (VOCs), including siloxanes, which shine and smooth hair. The scientists report that using these hair care products can change indoor air composition quickly, and common heat styling techniques -- straightening and curling -- increase VOC levels even more.
Published Future floods: Global warming intensifies heavy rain -- even more than expected
(via sciencedaily.com) Original source The intensity and frequency of extreme rainfall increases exponentially with global warming, a new study finds. The analysis shows that state-of-the-art climate models significantly underestimate how much extreme rainfall increases under global warming -- meaning that extreme rainfall could increase quicker than climate models suggest.
Published Sensitive ecosystems at risk from mine waste
(via sciencedaily.com) Original source Nearly a third of the world's mine tailings are stored within or near protected conservation areas, new research has found.
Published Deoxygenation levels similar to today's played a major role in marine extinctions during major past climate change event
(via sciencedaily.com) Original source Scientists have made a surprising discovery that sheds new light on the role that oceanic deoxygenation (anoxia) played in one of the most devastating extinction events in Earth's history. Their finding has implications for current day ecosystems -- and serves as a warning that marine environments are likely more fragile than apparent. New research, published today in leading international journal Nature Geosciences, suggests that oceanic anoxia played an important role in ecosystem disruption and extinctions in marine environments during the Triassic--Jurassic mass extinction, a major extinction event that occurred around 200 million years ago. Surprisingly however, the study shows that the global extent of euxinia (an extreme form of de-oxygenated conditions) was similar to the present day.
Published New method verifies carbon capture in concrete
(via sciencedaily.com) Original source Carbon capture is essential to reduce the impact of human carbon dioxide emissions on our climate. Researchers have developed a method to confirm whether carbon in concrete originates from the raw materials, or from carbon in the air which has been trapped when it reacts with the concrete to form the mineral calcium carbonate. By measuring the ratio of certain carbon isotopes in concrete that had been exposed to the air and concrete that hadn't, the team could successfully verify that direct air carbon capture had occurred. This method could be useful for the industrial sector and countries looking to offset their carbon emissions.
