| An edible QR code takes a shot at fake whiskey Posted: 06 Jun 2022 10:44 AM PDT Biomedical engineers have developed an edible silk tag with a QR code, which scanned by a smartphone can then confirm authenticity of the whiskey or other liquids, such as liquid medications. |
| Researchers create 'time machine' simulations studying the lifecycle of ancestor galaxy 'cities' Posted: 06 Jun 2022 08:15 AM PDT Researchers have created time machine-like simulations recreate the full life cycle of some of the largest collections of galaxies observed in the distant universe 11 billion years ago. |
| Vocal non-native songbird could change Britain's dawn chorus as we know it Posted: 06 Jun 2022 08:15 AM PDT A tiny but loud, brightly colored songbird from subtropical Asia could be emerging as a new invasive species in Britain, threatening to dominate the dawn chorus of native Robins, Blackbirds and warblers. A new study warns the Red-billed Leiothrix could become as familiar in gardens, parks and woodland as Ring-necked Parakeets. |
| Posted: 06 Jun 2022 08:15 AM PDT Over 200 years ago, a Spanish botanist described Artocarpus odoratissimus, a species of fruit-bearing tree found in Borneo and the Philippines. The Iban people, who are Indigenous to Borneo, know the tree to have two different varieties, which they call lumok and pingan, distinguished by their fruit size and shape. Despite this knowledge, Western botanists have long considered the tree as a single species, but a genetic analysis confirms the Iban people were right all along. |
| Including all types of emissions shortens timeline to reach Paris Agreement temperature targets Posted: 06 Jun 2022 08:15 AM PDT Looking beyond carbon dioxide emissions to include other human-generated pollutants, like methane, nitrogen oxide and particulate pollution, changes the picture for how much warming is already 'baked in' to the climate system. Earth will continue to warm even if all emissions cease, and Earth will be committed to reaching peak temperatures about five to 10 years before experiencing them. |
| Molecules found in mucus can thwart fungal infection Posted: 06 Jun 2022 08:15 AM PDT Researchers have identified components of mucus that can specifically interact with the fungus Candida albicans and prevent it from causing infection. These molecules, known as glycans, are a major constituent of mucins, the gel-forming polymers that make up mucus. |
| Beyond 'plant trees!': Research finds tree plantations encroaching on essential ecosystems Posted: 06 Jun 2022 08:15 AM PDT Trees planted in the tropics as part of nations' reforestation commitments can have unintended consequences, sometimes degrading biodiversity hotspots, damaging ecosystems like grasslands, or encroaching on protected areas. |
| Body versus brain: New evidence for an autoimmune cause of schizophrenia Posted: 06 Jun 2022 08:15 AM PDT Researchers have found that some people with schizophrenia have autoantibodies -- which are made by the immune system and recognize the body's own proteins, rather than outside threats such as viruses or bacteria -- against NCAM1, a protein that's important for communication between brain cells. The patients' autoantibodies also caused schizophrenia-related behaviors in mice. These findings may improve the diagnosis and treatment of a subset of patients with schizophrenia. |
| New model finds best sites for electric vehicle charging stations Posted: 06 Jun 2022 07:56 AM PDT Researchers have developed a computational model that can be used to determine the optimal places for locating electric vehicle charging facilities, as well as how powerful the charging stations can be without placing an undue burden on the local power grid. |
| Sharp X-ray images despite imperfect lenses Posted: 06 Jun 2022 07:56 AM PDT X-rays make it possible to explore inside human bodies or peer inside objects. The technology used to illuminate the detail in microscopically small structures is the same as that used in familiar situations -- such as medical imaging at a clinic or luggage control at the airport. X-ray microscopy enables scientists to study the three-dimensional structure of materials, organisms or tissues without cutting and damaging the sample. Unfortunately, the performance of X-ray microscopy is limited by the difficulties in producing the perfect lens. A team has now shown that, despite the manufacturing limitations of lenses, a much higher image quality and sharpness than ever before can be achieved using a special experimental arrangement and numerical image reconstruction downstream: an algorithm compensates for the deficits of the lenses. |
| Red pandas face a fractured future Posted: 06 Jun 2022 07:56 AM PDT The much-loved red panda is renowned for its tree-climbing ability and adorable nature, but new research shows the endangered mammal is being driven closer to extinction. |
| Intersecting light beams key in transformative 3D printer potential Posted: 06 Jun 2022 07:56 AM PDT Researchers have used intersecting light beams to control chemical reactions in an advanced material, paving the way for future use in 3D printers that print entire layers, instead of single points, at a time. |
| Molecular mechanism behind migration revealed in salt-seeking worms Posted: 06 Jun 2022 07:56 AM PDT Researchers have uncovered the molecular mechanism responsible for turning migratory actions on and off in nematode worms. The team found that the protein syntaxin plays a vital role in storing memory in the nervous system, and that altering it can affect the migratory behavior of nematodes. This line of research could one day help us better understand the migratory behavior of larger species such as mammals. |
| New way to identify influenza A virus lights up when specific virus targets are present Posted: 06 Jun 2022 07:56 AM PDT In order to quickly detect the presence of the influenza A virus, researchers developed a fluorogenic probe that could bind to the promoter region. A fluorogenic probe uses tiny molecules called fluorophores that emit light when a specific target is present. |
| Scientists use robots to reveal how predatory fish cope with unpredictable prey Posted: 06 Jun 2022 07:56 AM PDT Scientists have demonstrated how predators overcome their preys' erratic behavior by adapting their own during the hunt. |
| Power up: New polymer property could boost accessible solar power Posted: 06 Jun 2022 06:15 AM PDT Researchers have observed structural chirality, a biological property important to photosynthesis, emerging in achiral conjugated polymers. Their discovery could help enhance flexible solar cell design and increase access to affordable renewable energy. |
| Posted: 05 Jun 2022 10:03 AM PDT A scientist comments on the evolving treatment of rectal cancer in light of findings from a study that found the immunotherapy drug dostarlimab was especially effective in a phase II clinical trial of a dozen patients with a subtype of rectal cancer. |
| Removing barriers to opioid use disorder treatment shows success during pandemic Posted: 04 Jun 2022 05:29 AM PDT Pandemic-era changes to prescribing guidelines for the lifesaving drug buprenorphine led to improved treatment outcomes for patients with opioid use disorder in Philadelphia, according to a recently published study. |
| Novel method for early disease detection using DNA droplets Posted: 03 Jun 2022 12:33 PM PDT Droplet systems such as DNA droplets, which are formed by liquid-liquid phase separation of macromolecules, play an essential role in cellular functions. Now, by combining the technologies of DNA droplets and DNA computing, computational DNA droplets have been developed, which can recognize specific patterns in tumor biomarker microRNA sequences. |
