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 Scientists deliver quantum algorithm to develop new materials and chemistry
(via sciencedaily.com) Original source Scientists published the Cascaded Variational Quantum Eigensolver (CVQE) algorithm in a recent article, expected to become a powerful tool to investigate the physical properties in electronic systems.
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 The world is one step closer to secure quantum communication on a global scale
(via sciencedaily.com) Original source Researchers have brought together two Nobel prize-winning research concepts to advance the field of quantum communication. Scientists can now efficiently produce nearly perfect entangled photon pairs from quantum dot sources.
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 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 Quantum interference could lead to smaller, faster, and more energy-efficient transistors
(via sciencedaily.com) Original source Scientists made a single-molecule transistor using quantum interference to control electron flow. This new design offers high on/off ratio and stability, potentially leading to smaller, faster, and more energy-efficient devices. Quantum interference also improves the transistor's sensitivity to voltage changes, further boosting its efficiency.
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 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 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 Researchers invent artificial intelligence model to design new superbug-fighting antibiotics
(via sciencedaily.com) Original source Researchers at McMaster University and Stanford University have invented a new generative artificial intelligence model which can design billions of new antibiotic molecules that are inexpensive and easy to build in the laboratory.
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.
Published Rose essential oil: A safe pesticide for organic agriculture
(via sciencedaily.com) Original source Following injury, plants release terpenoids to enhance their defenses. Researchers studying terpenoid-enriched essential oils (EOs) have found that rose EO (REO) can stimulate defense genes in tomato leaves. Furthermore, REO attracts herbivores that protect the plant from the moth species, Spodoptera litura, and Tetranychus urticae, a mite pest. This suggests that applying REO could be a sustainable approach to pest management in organic farming.
Published As we age, our cells are less likely to express longer genes
(via sciencedaily.com) Original source Aging may be less about specific 'aging genes' and more about how long a gene is. Many of the changes associated with aging could be occurring due to decreased expression of long genes, say researchers. A decline in the expression of long genes with age has been observed in a wide range of animals, from worms to humans, in various human cell and tissue types, and also in individuals with neurodegenerative disease. Mouse experiments show that the phenomenon can be mitigated via known anti-aging factors, including dietary restriction.
Published Entanglements of humpback whales in fish farms rare -- and naivety could be to blame
(via sciencedaily.com) Original source The first study of humpback whale entanglements in B.C. aquaculture facilities found eight over 13 years, with the curiosity of young whales a potential contributing factor.
Published N-channel diamond field-effect transistor
(via sciencedaily.com) Original source A research team has developed an n-channel diamond MOSFET (metal-oxide-semiconductor field-effect transistor). The developed n-channel diamond MOSFET provides a key step toward CMOS (complementary metal-oxide-semiconductor: one of the most popular technologies in the computer chip) integrated circuits for harsh-environment- applications as well as the development of diamond power electronics.
