Published A novel stem cell adhesive using mussels
(via sciencedaily.com) Original source A team of researchers develops stem cell adhesive for arthritis treatment using mussel adhesion protein and hyaluronic acid.
Published World tour for model boat inspiring citizen science against environmental pollution
(via sciencedaily.com) Original source A model sailing boat which represents a key part of a project working to banish single use plastics has embarked on a global tour that will help its message reach thousands more people and communities across the planet.
Published Chances of eliminating HIV infection increased by novel dual gene-editing approach
(via sciencedaily.com) Original source Gene-editing therapy aimed at two targets -- HIV-1, the virus that causes AIDS, and CCR5, the co-receptor that helps the virus get into cells -- can effectively eliminate HIV infection, new research shows. The study combines a dual gene-editing strategy with antiretroviral drugs to cure animals of HIV-1.
Published Scientists present evidence for a billion-years arms race between viruses and their hosts
(via sciencedaily.com) Original source Researchers have proposed a new evolutionary model for the origin of a kingdom of viruses called Bamfordvirae, suggesting a billion-years evolutionary arms race between two groups within this kingdom and their hosts.
Published A stormy, active sun may have kickstarted life on Earth
(via sciencedaily.com) Original source The first building blocks of life on Earth may have formed thanks to eruptions from our Sun, a new study finds. A series of chemical experiments show how solar particles, colliding with gases in Earth's early atmosphere, can form amino acids and carboxylic acids, the basic building blocks of proteins and organic life.
Published Wiggly proteins guard the genome
(via sciencedaily.com) Original source Dynamic network in the pores of the nuclear envelope blocks dangerous invaders.
Published Researchers discover that the ice cap is teeming with microorganisms
(via sciencedaily.com) Original source Greenlandic ice is teeming with life, both on the surface and underneath. There are microscopic organisms that until recently science had no idea existed. There is even evidence to suggest that the tiny creatures color the ice and make it melt faster.
Published Prolonged power outages, often caused by weather events, hit some parts of the U.S. harder than others
(via sciencedaily.com) Original source New research found that Americans already bearing the brunt of climate change and health inequities are most at risk of impact by a lengthy power outage.
Published West Antarctic Ice Sheet retreated far inland, re-advanced since last Ice Age
(via sciencedaily.com) Original source The West Antarctic Ice Sheet is melting rapidly, raising concerns it could cross a tipping point of irreversible retreat in the next few decades if global temperatures rise 1.5 to 2.0 degrees Celsius (2.7 to 3.8 degrees Fahrenheit) above preindustrial levels. New research finds that 6,000 years ago, the grounded edge of the ice sheet may have been as far as 250 kilometers (160 miles) inland from its current location, suggesting the ice retreated deep into the continent after the end of the last ice age and re-advanced before modern retreat began.
Published Exposure to airplane noise increases risk of sleeping fewer than 7 hours per night
(via sciencedaily.com) Original source As major airline officials predict another record summer air travel season, a new analysis has found that exposure to even moderate levels of airplane noise may disrupt sleep, building upon a growing body of research on the adverse health effects of environmental noise. People who were exposed to airplane noise at levels as low as 45 dB were more likely to sleep less than 7 hours per night. For comparison, the sound of a whisper is 30 dB, a library setting is 40 dB, and a typical conversation at home is 50 dB.
Published Herpes study adds to understanding of viral reinfections, how to potentially prevent them
(via sciencedaily.com) Original source A new study on herpes infections of the eye helps shed light on the question of viral reinfections by identifying a key protein involved in viral reinfections that could be targeted by antiviral drugs.
Published Harmful fisheries subsidies are leading to more fishing vessels chasing fewer fish, resulting in adverse environmental and societal impacts
(via sciencedaily.com) Original source A recent study quantified the number of harmful fisheries subsidies that support fishing in the high seas, domestic and foreign waters and found that between 20 and 37 per cent of these subsidies supported fishing in waters outside the jurisdictions of their home nation. Further, these subsidies also primarily originated from developed nations, yet disproportionately impacted developing countries, leading to environmental and societal impacts all around the globe.
Published Machine learning helps scientists identify the environmental preferences of microbes
(via sciencedaily.com) Original source A machine-learning approach can give scientists insight into the environmental preferences of microbes, based only on their genes. The approach has practical research implications: it could help researchers more efficiently grow bacteria in the laboratory. It could also lead to smarter use of microbes in agriculture, ecological restoration, and even probiotics.
Published Previously unknown intercellular electricity may power biology
(via sciencedaily.com) Original source Researchers have discovered that the electrical fields and activity that exist through a cell's membrane also exist within and around another type of cellular structure called biological condensates. Like oil droplets floating in water, these structures exist because of differences in density. Their foundational discovery could change the way researchers think about biological chemistry. It could also provide a clue as to how the first life on Earth harnessed the energy needed to arise.
Published Mushrooms and their post-rain, electrical conversations
(via sciencedaily.com) Original source Certain types of fungi can communicate with each other via electrical signals. But much remains unknown about how and when they do so. A group of researchers recently headed to the forest to measure the electrical signals of Laccaria bicolor mushrooms, finding that their electrical signals increased following rainfall.
Published Artificial photosynthesis for environmentally friendly food production
(via sciencedaily.com) Original source Ensuring the supply of food to the constantly growing world population and protecting the environment at the same time are often conflicting objectives. Now researchers have successfully developed a method for the synthetic manufacture of a nutritional protein using a type of artificial photosynthesis. The animal feed industry is the primary driver of high demand for large volumes of this nutritional protein L-alanine, which is also suitable for use in meat substitute products.
Published Scientists identify antivirals that could combat emerging infectious diseases
(via sciencedaily.com) Original source A new study has identified potential broad-spectrum antiviral agents that can target multiple families of RNA viruses that continue to pose a significant threat for future pandemics.
Published Plastic particles themselves, not just chemical additives, can alter sex hormones
(via sciencedaily.com) Original source A new study used a pioneering technique to deliver endocrine-disrupting aerosolized micro-nano-plastics to female lab rats.
Published The reasons why insect numbers are decreasing
(via sciencedaily.com) Original source Researchers are investigating the causes and consequences of the worldwide insect decline as well as considering potential countermeasures.
Published The future is foggy for Arctic shipping
(via sciencedaily.com) Original source As the Arctic warms and loses sea ice, trans-Arctic shipping has increased, reducing travel time and costs for international trade. However, a new study finds that the Arctic Ocean is getting foggier as ice disappears, reducing visibility and causing costly delays as ships slow to avoid hitting dangerous sea ice.
