| Researchers develop advanced model to improve safety of next-generation reactors Posted: 21 May 2021 10:13 AM PDT When one of the largest modern earthquakes struck Japan on March 11, 2011, the nuclear reactors at Fukushima-Daiichi automatically shut down, as designed. The emergency systems, which would have helped maintain the necessary cooling of the core, were destroyed by the subsequent tsunami. Because the reactor could no longer cool itself, the core overheated, resulting in a severe nuclear meltdown, the likes of which haven't been seen since the Chernobyl disaster in 1986. |
| New mode of transmission for bacteria Posted: 21 May 2021 10:13 AM PDT Campylobacter infection, one of the most common foodborne illnesses in the Western world, can also be spread through sexual contact, according to a new research. |
| Who's in this ocean? Tracking down species on the go using environmental DNA Posted: 21 May 2021 08:53 AM PDT A group of researchers carried out eDNA sequencing on jelly fish in the Florida Keys using a newly developed Fieldable eDNA sequencing kit to identify species that may be endangered, invasive or dangerous. |
| Gene that causes canine hereditary deafness in puppies Posted: 21 May 2021 08:53 AM PDT Researchers have been the first to determine the cause for the nonsyndromic early-onset hereditary canine hearing loss in Rottweilers. The gene defect was identified in a gene relevant to the sense of hearing. The study can also promote the understanding of mechanisms of hearing loss in human. |
| In utero exposure to tiny air pollution particles is linked to asthma in preschoolers Posted: 21 May 2021 06:45 AM PDT Women who were highly exposed to ultra-fine particles in air pollution during their pregnancy were more likely to have children who developed asthma, according to a new study. This is the first time asthma has been linked with prenatal exposure to this type of air pollution, which is named for its tiny size and which is not regulated or routinely monitored in the United States. |
| A tripartite-chromosome E. coli strain allows the chromosome isolation and implantation Posted: 21 May 2021 06:44 AM PDT A group of researchers has succeeded in splitting the E. coli chromosome into three of 1 million base pairs. The 1 million base pairs chromosome can be used for E. coli transformation. This E. coli-based technology has the potential to greatly advance synthetic genomics. |
| Posted: 21 May 2021 05:19 AM PDT More than 100 kg of highly toxic uranium (U) and plutonium (Pu) was dispersed in the form of tiny 'hot' radioactive particles after the British detonated nine atomic bombs in remote areas of South Australia, including Maralinga. |
| Scientists discover gene signature for plaque-eating microglia in Alzheimer's Disease Posted: 21 May 2021 05:19 AM PDT Single-cell gene studies are clarifying the roles of the brain's specialised immune cell in Alzheimer's disease and offer new avenues for treatment of this incurable condition. |
| An updated understanding of how to synthesize value-added chemicals Posted: 20 May 2021 01:03 PM PDT New research provides an updated understanding of how to add functional groups onto simple hydrocarbons like methane. This new and highly detailed mechanism is a crucial step towards designing the next generation of catalysts and finding scalable approaches for turning greenhouse gases into value-added chemicals. |
| Multi-story buildings made of wood sell for 9% more than other construction in Helsinki Posted: 20 May 2021 10:39 AM PDT Building more homes and buildings with wood has been on the radar for years as a way to offset carbon emissions, though construction companies have been hesitant to take the material in broader use. A study is now the first to show that building with wood can be a sound investment. The findings show that multi-storied buildings made out of wood sold for an average of 8.85% more than those made from other materials. |
| Radar tracking uncovers mystery of where honeybee drones have sex Posted: 20 May 2021 10:39 AM PDT Scientists have used radar technology to track male honeybees, called drones, and reveal the secrets of their mating behaviors. |
| Technique uses fluctuations in video pixels to measure energy use of developing embryos Posted: 20 May 2021 10:39 AM PDT Researchers have developed a cutting edge technique which enables them to instantly examine the biological traits and behaviors of developing embryos as an energy signature, rather than focusing on individual characteristics. |
| Solving a natural riddle of water filtration Posted: 20 May 2021 10:39 AM PDT Engineers have found a way to replicate a natural process that moves water between cells, with a goal of improving how we filter out salt and other elements and molecules to create clean water while consuming less energy. |
| Molecule enlists patient's immune system to combat HIV Posted: 20 May 2021 10:38 AM PDT Antiretroviral therapy, the common approach in the treatment of HIV, halts replication of the virus and has saved the lives of millions of people. However, for patients the drug cocktail becomes a lifetime necessity because they continue to harbor latent HIV in a small number of immune system cells. In the absence of treatment, HIV can again replicate and rebound into full blown AIDs. |
| Challenging the standard model of cancer Posted: 20 May 2021 10:38 AM PDT In spite of decades of research, cancer remains an enigma. Conventional wisdom holds that cancer is driven by random mutations that create aberrant cells that run amok in the body. Researchers challenge this model by proposing that cancer is a type of genetic throwback, that progresses via a series of reversions to ancestral forms of life. |
| Parrot poachers striking while the market's hot Posted: 20 May 2021 10:38 AM PDT 'Pretty' parrots are more likely to be snatched up for Indonesia's illegal wildlife trade, a new study reveals. The findings not only expose the key drivers behind the country's illegal trade in these birds, but offer lessons for the potential emergence and spread of infectious diseases that jump from animals to humans. |
| Solar geoengineering may be effective in alleviating impacts of global warming on crops Posted: 20 May 2021 10:37 AM PDT Solar geoengineering is not a fix-all for climate change but it could be one of several tools to manage climate risks. A growing body of research has explored the ability of solar geoengineering to reduce physical climate changes. But much less is known about how solar geoengineering could affect the ecosystem and, particularly, agriculture. Now, research finds that solar geoengineering may be surprisingly effective in alleviating some of the worst impacts of global warming on crops. |
| A stressful life in the city affects birds' genes Posted: 20 May 2021 10:37 AM PDT Great tits living in cities are genetically different from great tits in the countryside. This is what researchers have found in a unique study, where they examined populations of great tits in nine large European cities. |
| High risk of conflict between humans and elephants and lions Posted: 20 May 2021 10:37 AM PDT Scientists have identified the areas that are most at risk for conflicts between humans and elephants and lions in Africa. |
| The driving force behind tropical mudslides Posted: 20 May 2021 10:37 AM PDT Geological knowledge is essential for predicting what areas in a tropical mountain range are more prone to have landslides, earthquakes and volcanic eruptions, and the catastrophic consequences that these events might have in the surrounding populations. |
| Economics and value of pollination Posted: 20 May 2021 10:37 AM PDT Scientists examine pollinators from both an economic and ecological perspective, providing much needed insight into the complexities of valuing pollination. This recent collaboration highlights the importance of characterizing the economic value of pollination services, including that of managed and wild pollinators, both for the sustainability of honey bee markets and the protection of overall ecosystem health. |
