Published Bees use antennae to decode hive mates' dances in the dark
(via sciencedaily.com) Original source Scientists have discovered how honeybees can decipher dances by their hive mates that relay directions to food.
Published Global study of coastal seas as carbon dioxide reservoirs
(via sciencedaily.com) Original source Coastal seas form a complex transition zone between the two largest CO2 sinks in the global carbon cycle: land and ocean. Ocean researchers have now succeeded for the first time in investigating the role of the coastal ocean in a seamless model representation.
Published Citizen scientists contribute vital information about 35 seahorse species
(via sciencedaily.com) Original source Thanks to diligent observers, seahorses, those enigmatic and charismatic fish, are not only being discovered in new habitats and expanded geographic ranges, they are also being found at new ocean depths. While their capacity for male pregnancy has long fascinated people, new information on sex ratio and pregnancy seasonality has been discovered.
Published 'Winners and losers' as global warming forces plants uphill
(via sciencedaily.com) Original source Some plant species will 'win' and others will 'lose' as global warming forces them to move uphill, new research shows.
Published Breakthrough antibiotic shows promise against obstinate mycobacterial infections
(via sciencedaily.com) Original source A team of scientists has developed a novel antibiotic named COE-PNH2 that is capable of combating hard-to-treat mycobacterial lung infections. Such infections, which are notorious for resisting conventional treatment, pose a serious health threat, especially to the elderly and those with underlying conditions.
Published Small changes can yield big savings in agricultural water use
(via sciencedaily.com) Original source While Hollywood and Silicon Valley love the limelight, California is an agricultural powerhouse, too. Agricultural products sold in the Golden State totaled $59 billion in 2022. But rising temperatures, declining precipitation and decades of over pumping may require drastic changes to farming. Legislation to address the problem could even see fields taken out of cultivation.
Published Humans pass more viruses to other animals than we catch from them
(via sciencedaily.com) Original source Humans pass on more viruses to domestic and wild animals than we catch from them, according to a major new analysis of viral genomes.
Published Better phosphorus use can ensure its stocks last more than 500 years and boost global food production
(via sciencedaily.com) Original source More efficient use of phosphorus could see limited stocks of the important fertilizer last more than 500 years and boost global food production to feed growing populations. But these benefits will only happen if countries are less wasteful with how they use phosphorus, a study shows. Around 30-40 per cent of farm soils have over-applications of phosphorus, with European and North American countries over-applying the most.
Published Caller ID of the sea: Tagging whale communication and behavior
(via sciencedaily.com) Original source Biologists use a novel method of simultaneous acoustic tagging to gain insights into the link between whale communication and behavior
Published Wild bird gestures 'after you'
(via sciencedaily.com) Original source A small-bird species, the Japanese tit (Parus minor), uses wing movements as a gesture to convey the message 'after you,' according to new research. When a mating pair arrives at their nest box with food, they will wait outside on perches. One will then often flutter its wings toward the other, apparently indicating for the latter to enter first. The researchers say that this discovery challenges the previous belief that gestural communication is prominent only in humans and great apes, significantly advancing our understanding of visual communication in birds.
Published Researchers discover evolutionary 'tipping point' in fungi
(via sciencedaily.com) Original source Scientists have found a 'tipping point' in the evolution of fungi that throttles their growth and sculpts their shapes. The findings demonstrate how small changes in environmental factors can lead to huge changes in evolutionary outcomes.
Published Natural recycling at the origin of life
(via sciencedaily.com) Original source How was complex life able to develop on the inhospitable early Earth? At the beginning there must have been ribonucleic acid (RNA) to carry the first genetic information. To build up complexity in their sequences, these biomolecules need to release water. On the early Earth, which was largely covered in seawater, that was not so easy to do.
Published Bees need food up to a month earlier than provided by recommended pollinator plants
(via sciencedaily.com) Original source Plant species which are recommended as 'pollinator friendly' in Europe begin flowering up to a month too late for bees, resulting in low colony survival and low production of queens. This research has quantified the decline in colony survival and queen production due to a shortage of early season food. Enhancing existing hedgerows with early blooming species has the potential to increase the probability that a bee colony survives from 35% to 100%.
Published Major environmental benefits recycling gold with biodiesel
(via sciencedaily.com) Original source Researchers have developed an environmentally friendly method for recycling and purifying metals. Using gold earrings from a pawnshop in Gothenburg and biodiesel from the nearest filling station, the discovery could change an industry that is currently dependent on large amounts of fossil oil.
Published Enormous ice loss from Greenland glacier
(via sciencedaily.com) Original source Ground-based measuring devices and aircraft radar operated in the far northeast of Greenland show how much ice the 79 N-Glacier is losing. According to recent measurements, the thickness of the glacier has decreased by more than 160 meters since 1998. Warm ocean water flowing under the glacier tongue is melting the ice from below. High air temperatures cause lakes to form on the surface, whose water flows through huge channels in the ice into the ocean. One channel reached a height of 500 meters, while the ice above was only 190 meters thick.
Published Your dog understands that some words 'stand for' objects
(via sciencedaily.com) Original source It's no surprise that your dog can learn to sit when you say 'sit' and come when called. But a new study has made the unexpected discovery that dogs generally also know that certain words 'stand for' certain objects. When dogs hear those words, brain activity recordings suggest they activate a matching mental representation in their minds.
Published Research uncovers a rare resin fossil find: A spider that aspires to be an ant
(via sciencedaily.com) Original source Spiders that disguise themselves as ants live in many locations around the globe but until now most had been able to avoid detection from fossil researchers as well as predators.
Published Signs of life would be detectable in single ice grain emitted from extraterrestrial moons
(via sciencedaily.com) Original source Could life be found in frozen sea spray from moons orbiting Saturn or Jupiter? New research finds that life can be detected in a single ice grain containing one bacterial cell or portions of a cell. The results suggest that if life similar to that on Earth exists on these planetary bodies, that this life should be detectable by instruments launching in the fall.
Published Product that kills agricultural pests also deadly to native Pacific Northwest snail
(via sciencedaily.com) Original source A product used to control pest slugs on farms in multiple countries is deadly to least one type of native woodland snail endemic to the Pacific Northwest, according to scientists who say more study is needed before the product gains approval in the United States.
Published Evolutionary history of the formation of forceps and maternal care in earwigs
(via sciencedaily.com) Original source Researchers examined the developmental processes and reproduction-related behavior of 8 of the 11 families of Dermaptera (earwigs) in detail and compared with those reported in previous studies. The results confirmed that Dermaptera is a polyneopteran order, and the features such as caudal forceps and elaborate maternal care for eggs and young larvae emerged in parallel within the order during evolution.
