| How to block new antibiotic resistance gene Posted: 19 Feb 2019 02:01 PM PST A new antimicrobial-resistance gene, VCC-1, a beta-lactamase gene, has been discovered in benign close relatives of virulent Vibrio cholerae, which causes cholera. Now, a team of Canadian researchers has found a way to block the VCC-1 enzyme, which disables that resistance gene. |
| Antibiotic resistances spread faster than thought, aquaculture study reveals Posted: 19 Feb 2019 02:01 PM PST By studying fish raised in aquaculture, researchers have shed new light on the mechanisms by which antibiotic resistance genes are transferred between bacteria. According to their study, those mechanisms are more varied than previously thought. |
| Cervical microbiome may promote high-grade precancerous lesions Posted: 19 Feb 2019 02:01 PM PST Infections with a Human Papillomavirus (HPV) cause 99 percent of cervical cancer cases, and the disease's first sign is often the appearance of precancerous lesions on a woman's cervix. But bacteria may play an important role, too. New research suggests that the cervical microbiome may influence HPV infection more than researchers previously thought. |
| Carbon taxes could create new winners and losers among countries, research says Posted: 19 Feb 2019 12:52 PM PST A global carbon tax would create new sets of economic winners and losers, with some countries holding a distinct competitive advantage over others, according to new research. |
| Prenatal forest fire exposure stunts children's growth Posted: 19 Feb 2019 12:51 PM PST Forest fires are more harmful than previously imagined, causing stunted growth in children who were exposed to smoke while in the womb, according to new research. |
| Pottery reveals America's first social media networks Posted: 19 Feb 2019 11:35 AM PST Long before Snapchat, Instagram, Facebook and even MySpace, early Mississippian Mound cultures in America's southern Appalachian Mountains shared artistic trends and technologies across regional networks that functioned in similar ways as modern social media, suggests new research. |
| Marsupial lived among Arctic dinosaurs Posted: 19 Feb 2019 10:29 AM PST A research team has discovered a previously unknown species of marsupial that lived in Alaska's Arctic during the era of dinosaurs, adding a vivid new detail to a complex ancient landscape. The thumb-sized animal, named Unnuakomys hutchisoni, lived in the Arctic about 69 million years ago during the late Cretaceous Period. |
| Posted: 19 Feb 2019 10:29 AM PST When compressed, a material typically becomes a better conductor of heat. Not so for the unusual material cubic boron arsenide, which when under pressure shows its conductivity first improves and then deteriorates. The findings not only hint at future applications, but proffer a theory that may offer insights into some of the oldest Earth processes. |
| Renewable energy generation with kites and drones Posted: 19 Feb 2019 10:27 AM PST A group of researchers has recently developed a new software aimed at the analysis of energy generation systems based on kites and drones. They used the software to study the behavior of these systems while transforming the kinetic energy of the wind into useful electrical energy. |
| Plants can skip the middlemen to directly recognize disease-causing fungi Posted: 19 Feb 2019 10:26 AM PST Scientists have revealed that direct physical associations between plant immune proteins and fungal molecules are widespread during attempted infection. The authors' findings run counter to current thinking and may have important implications for engineering disease resistance in crop species. |
| Using crystals to unpick how viruses work Posted: 19 Feb 2019 10:26 AM PST Researchers have used X-ray crystallography and computer simulation to get a closer look at how viruses bind cells and cause infection. |
| Lobster's underbelly is as tough as industrial rubber Posted: 19 Feb 2019 10:26 AM PST Flip a lobster on its back, and you'll see that the underside of its tail is split in segments connected by a translucent membrane that appears rather vulnerable when compared with the armor-like carapace that shields the rest of the crustacean. But engineers have found that this soft membrane is surprisingly tough, with a microscopic, layered, plywood-like structure that makes it remarkably tolerant to scrapes and cuts. |
| Fishing and pollution regulations don't help corals cope with climate change Posted: 19 Feb 2019 08:18 AM PST A new study reports that protecting coral reefs from fishing and pollution does not help coral populations cope with climate change. The study also concludes that ocean warming is the primary cause of the global decline of reef-building corals and that the only effective solution is to immediately and drastically reduce greenhouse gas emissions. |
| Why North Carolinian boats are fishing off New Jersey's coast, and how a CSF might help Posted: 19 Feb 2019 08:18 AM PST By studying the logbooks of fishing boats, researchers found that some fishing boats travel more than 250 miles to catch the fish that used to be in local waters. In response, researchers began investigating how local community supported fishery programs -- like farm shares for fish -- can affect fishing communities. That resulted in the creation of Fishadelphia, a CSF based in a South Philadelphia charter school. |
| The key to increased lifespan? Rubicon alters autophagy in animals during aging Posted: 19 Feb 2019 08:17 AM PST Autophagy is an important biological recycling mechanism that influences the progression of aging in animals. Here, age-related changes in autophagy were studied in multiple model organisms. A team found that Rubicon suppression led to reduction of age-associated motor decline, as well as reduction of fibrosis, and that Rubicon could be an important new target for treatments designed to reduce the effects of aging in humans. |
| A lack of antibody diversity may make the elderly more susceptible to the flu Posted: 19 Feb 2019 08:17 AM PST The influenza vaccine may be less effective in the elderly because their B cells are less capable of producing antibodies that can adapt to protect against new viral strains, researchers report. With age, B cells and the antibodies they secrete acquire fewer mutations that would provide flexible protection against the ever-changing flu virus. |
| Birch pollen allergen immunotherapy normalizes nasal gene-expression and microbial community Posted: 19 Feb 2019 08:17 AM PST According to a new study, birch pollen allergen immunotherapy modifies the gene expression and microbiome profile of the nasal epithelium to correspond to those of healthy controls. |
| Ocean acidification harms cod larvae more than previously thought Posted: 19 Feb 2019 08:17 AM PST The Atlantic cod is one of the most important commercial fish species in the world. Recent studies have shown that ocean acidification threatens the early life stages of this species. So far it was hoped that at least the larvae that survive might be more robust and therefore may aid in the adaptation of this population. A new article suggests otherwise. |
| 20-million-year-old tusked sea cow is Central America's oldest marine mammal Posted: 19 Feb 2019 08:17 AM PST A researcher searching the shoreline of the Panama Canal for fossil plants instead found an ancient sea cow. An 'emergency fossil excavation' due to rising water levels yielded a remarkably complete skeleton of a new genus and species of dugong, estimated to be about 20 million years old, the first evidence of a marine mammal from the Pacific side of the canal. |
| The global impact of coal power Posted: 19 Feb 2019 08:17 AM PST With data and modelling from almost 8,000 coal power plants, researchers present the most comprehensive global picture to date of climate and human health impacts from coal power generation. |
| Forest fires as an opportunity for ecosystem recovery Posted: 19 Feb 2019 08:17 AM PST It is estimated that globally there are more than two million hectares of land in need of restoration. The fires that occurred in those places provided the people who manage them with an opportunity to change, via a suitable process of ecological restoration, the previous bad forestry practices. |
| Neanderthals' main food source was definitely meat Posted: 19 Feb 2019 08:17 AM PST Researchers describe two late Neanderthals with exceptionally high nitrogen isotope ratios, which would traditionally be interpreted as the signature of freshwater fish consumption. By studying the isotope ratios of single amino acids, they however demonstrated that instead of fish, the adult Neanderthal had a diet relying on large herbivore mammals and that the other Neanderthal was a breastfeeding baby whose mother was also a carnivore. |
| Total synthesis of marine antitumor agents trabectedin and lurbinectedin Posted: 19 Feb 2019 08:16 AM PST With its vast numbers of different lifeforms, the sea is a largely unexplored source of natural products that could be starting points for new pharmaceuticals, such as the antitumor drugs trabectedin and lurbinectedin. Because only tiny amounts can be obtained from sea organisms, synthetic production is necessary. Scientists have introduced a new, efficient synthetic route for these two drugs. A key step is the light-controlled activation of a carbon-hydrogen bond. |
| Natural resources valued differently by men and woman Posted: 19 Feb 2019 08:16 AM PST Men and women value, access and use resources from the natural environment in distinct and different ways, a new study has shown. |
| Oral antifungal drug used to treat yeast infections linked to higher rates of miscarriage Posted: 19 Feb 2019 05:07 AM PST A commonly used medication, fluconazole, used to treat vaginal yeast infections, is linked to higher rates of miscarriage if used during pregnancy, found new research. |
| Climate-friendly labriculture depends on an energy revolution Posted: 19 Feb 2019 05:07 AM PST In a first-of-its-kind study, the climate-change impact of several production methods for lab-grown and farmed beef was assessed accounting for the differing greenhouse gases produced. The new projections reveal that over the long term, cultured meat production methods requiring large energy inputs could increase global warming more than some types of cattle farming if energy systems remain dependent on fossil fuels. |
| Quarrying of Stonehenge 'bluestones' dated to 3000 BC Posted: 19 Feb 2019 05:07 AM PST Excavations at two quarries in Wales, known to be the source of the Stonehenge 'bluestones', provide new evidence of megalith quarrying 5,000 years ago. |
| World's biggest terrestrial carbon sinks are found in young forests Posted: 18 Feb 2019 12:31 PM PST More than half of the carbon sink in the world's forests is in areas where the trees are relatively young -- under 140 years old -- rather than in tropical rainforests, research shows. |
