| Nanostructured fibers can impersonate human muscles Posted: 03 Jun 2022 12:33 PM PDT Researchers have created a new type of fiber that can perform like a muscle actuator, in many ways better than other options that exist today. And, most importantly, these muscle-like fibers are simple to make and recycle. |
| Great timing, supercomputer upgrade lead to successful forecast of volcanic eruption Posted: 03 Jun 2022 12:33 PM PDT In the fall of 2017, a team of geologists had just set up a new volcanic forecasting modeling program on the Blue Waters and iForge supercomputers. Simultaneously, another team was monitoring activity at the Sierra Negra volcano in the Galapagos Islands, Ecuador. The teams shared their insights and what happened next was the fortuitous forecast of the June 2018 Sierra Negra eruption five months before it occurred. |
| Shaping up the genome for cell division Posted: 03 Jun 2022 09:49 AM PDT Our cells perform a marvel of engineering when it comes to packing information into small spaces. Every time a cell divides, it bundles up an amazing 4 meters of DNA into 46 tiny packages, each of which is only several millionths of a metre in length. Researchers have now discovered how a family of DNA motor proteins succeeds in packaging loosely arranged strands of DNA into compact individual chromosomes during cell division. |
| Ancient ocean floors could help in the search for critical minerals Posted: 03 Jun 2022 09:49 AM PDT Studying ancient ocean floors could help us discover minerals needed to produce electric cars and solar panels. |
| New insights into effects of membrane proteins on plant growth Posted: 03 Jun 2022 09:49 AM PDT Scientists have revealed two enzymes that regulate protein degradation of proteins in the cell membrane of plants, and established the roles they play in plant growth and development. |
| How simulations could help get PFAS out of soil Posted: 03 Jun 2022 09:48 AM PDT Chemists are discovering new information to help remediate 'forever chemicals' by showing for the first time how they interact with soil at the molecular level. |
| The link between temperature, dehydration and tectonic tremors in Alaska Posted: 03 Jun 2022 07:01 AM PDT No one is at their best when they are dehydrated and that goes for tectonic plates too. Researchers using a thermomechanical model of the Alaska subduction zone indicates that plate dehydration is at its highest in the region where low-frequency tremors occur, suggesting that the expelled water contributes towards these seimic events. This improved understanding will contribute to better predictions of future earthquakes. |
| Why confronting invasive species is one of the best ways to prepare for climate change Posted: 03 Jun 2022 07:01 AM PDT New research finds that the ecological effect of invasive species alone is comparable to the combined effects of invasives plus warming temperatures, drought or nitrogen deposition. This suggests that a critical preparation for climate change is to manage invasive species at the local level. |
| Fish cannibalism rare in wild, study finds Posted: 03 Jun 2022 07:01 AM PDT Mosquitofish and guppies, though known to be cannibalistic in captivity, are extremely unlikely to be cannibals in wild settings, and the rare instances of cannibalism in these fish are likely due to strong competition for food. |
| Posted: 03 Jun 2022 07:01 AM PDT Indiscriminate snaring for bushmeat hunting may have varying collateral effects on non-target species, ranging from mild injuries to death. Beyond immediate mortalities these effects are rarely examined. A team of scientists now analyzed the life-history consequences of debilitating snare injuries in individually known female spotted hyenas between 1987 and 2020 in the Serengeti National Park, Tanzania. The long-term data revealed that injuries did not decrease the age expectancy of the hyenas, but hampered their reproductive performance. Debilitating injuries caused by snares delayed their age at first reproduction, decreased the size of their litters and reduced the survival of their offspring. |
| How we choose to end deforestation will impact future emissions Posted: 03 Jun 2022 07:00 AM PDT Could the Glasgow Leaders' Declaration on Forests and Land Use's ambitions be too ambiguous? An international team of researchers looked into this question. |
| This parasite will self-destruct: Researchers discover new weapon against drug-resistant malaria Posted: 02 Jun 2022 11:08 AM PDT A new method to combat malaria which sees the disease turn against itself could offer an effective treatment for the hundreds of millions of people infected globally each year, as the efficacy of current antimalarial drugs weakens. The research has identified an anti-malarial compound, ML901, which inhibits the malaria parasite but does not harm mammalian -- human or other mammals' -- cells. |
| Posted: 02 Jun 2022 11:08 AM PDT An investigation into the evolution of Salmonella bacteria infecting Brazilian poultry shows that the introduction of a Salmonella vaccine, combined with increasing antibiotic usage by Brazilian farmers, has led to the rise of strains that are more antibiotic-resistant, but less likely to cause disease in humans. |
| How glyphosate affects brood care in bumblebees Posted: 02 Jun 2022 11:08 AM PDT Bumblebee colonies exposed to glyphosate are significantly affected in times of resource scarcity, according to recent research. |
| New blood test can help doctors diagnose tuberculosis and monitor treatment Posted: 01 Jun 2022 11:28 AM PDT Researchers have developed a new highly sensitive blood test for tuberculosis (TB) that screens for DNA fragments of the Mycobacterium tuberculosis bacteria that causes the deadly disease. |
| Famous rock art cave in Spain was used by ancient humans for over 50,000 years Posted: 01 Jun 2022 11:26 AM PDT A cave in southern Spain was used by ancient humans as a canvas for artwork and as a burial place for over 50,000 years, according to a new study. |
