Flooding damage to levees is cumulative -- and often invisible Posted: 21 Jan 2020 10:33 AM PST Recent research finds that repeated flooding events have a cumulative effect on the structural integrity of earthen levees, suggesting that the increase in extreme weather events associated with climate change could pose significant challenges for the nation's aging levee system. |
New species of antibiotic-resistant bacteria found in infected wound Posted: 21 Jan 2020 10:33 AM PST A hitherto unknown antibiotic-resistant bacteria species, in the same family as E. coli and Salmonella spp., has been found and classified in Sweden. The proposed taxonomic name of the species -- the first of the new genus -- is Scandinavium goeteborgense, after the city of Gothenburg, Sweden, where the bacterium was isolated and the research was done. |
Insect bites and warmer climate means double-trouble for plants Posted: 21 Jan 2020 10:33 AM PST Scientists think that current models are incomplete and that we may be underestimating crop losses. A new study shows that infested tomato plants, in their efforts to fight off caterpillars, don't adapt well to rising temperatures. This double-edged sword worsens their productivity. |
Walking sharks discovered in the tropics Posted: 21 Jan 2020 10:33 AM PST Four new species of tropical sharks that use their fins to walk are causing a stir in waters off northern Australia and New Guinea. |
To reverse engineer dynamics of microbial communities, researchers construct their own Posted: 21 Jan 2020 10:33 AM PST Scientific and public appreciation for microbes -- and the key role their communal actions play in environmental health, food production, and human wellness -- has grown in recent years. While initially considered to be static, uniform entities, microbial communities are highly complex and contain internal chemical swapfests that are in constant flux. Researchers have demonstrated that the dynamics of these communities can be explained and even predicted by examining the variability trait of microbial social interactions. |
Posted: 21 Jan 2020 10:33 AM PST Have I got a fish story for you. Any angler beginning a yarn like that usually ends up spinning a tall tale, an exaggeration or bald-faced lie. Researchers, however, have demonstrated that anglers can produce accurate and complex environmental models similar to those of trained scientists. |
Novel composite antimicrobial film could take a bite out of foodborne illnesses Posted: 21 Jan 2020 10:00 AM PST A novel composite film -- created by the bonding of an antimicrobial layer to conventional, clear polyethylene plastic typically used to vacuum-package foods such as meat and fish -- could help to decrease foodborne illness outbreaks, according to researchers. |
How fruit flies flock together in orderly clusters Posted: 21 Jan 2020 10:00 AM PST Opposing desires to congregate and maintain some personal space drive fruit flies to form orderly clusters, according to a new study. |
Feeding the world without wrecking the planet is possible Posted: 21 Jan 2020 09:40 AM PST A study now suggests a comprehensive solution package for feeding 10 billion people within our planet's environmental boundaries. Supplying a sufficient and healthy diet for every person whilst keeping our biosphere largely intact will require no less than a technological and socio-cultural U-turn. It includes adopting radically different ways of farming, reduction of food waste, and dietary changes. |
A chronicle of giant straight-tusked elephants Posted: 21 Jan 2020 09:40 AM PST About 800,000 years ago, the giant straight-tusked elephant Palaeoloxodon migrated out of Africa and became widespread across Europe and Asia. |
Blue light triggers memory and emphatic fear in mice via a non-invasive approach Posted: 21 Jan 2020 09:39 AM PST Researchers have engineered an improved biological tool that controls calcium (Ca2+) levels in the brain via blue light. This monster-OptoSTIM1 causes a change in mice's fear learning behavior without the need of optic fiber implants in the brain. |
Modified plants to curb climate change Posted: 21 Jan 2020 09:39 AM PST New technologies are needed to combat climate change. Now bioinformatics specialists might have found a way of enabling plants to store more carbon dioxide. |
Emissions of potent greenhouse gas have grown, contradicting reports of huge reductions Posted: 21 Jan 2020 08:30 AM PST Despite reports that global emissions of the potent greenhouse gas were almost eliminated in 2017, an international team of scientists has found atmospheric levels growing at record values. |
Parrots collaborate with invisible partners Posted: 21 Jan 2020 08:30 AM PST New study shows that peach-fronted conures have a surprisingly advanced talent for collaboration when it comes to finding food. This is important knowledge for biologists working with conservation of wild bird populations. |
Warmer and acidified oceans can lead to 'hidden' changes in species behavior Posted: 21 Jan 2020 08:30 AM PST Scientists have shown that the peppery furrow shell (Scrobicularia plana) makes considerable changes to its feeding habits when faced with warmer and more acidified oceans. |
Posted: 21 Jan 2020 08:30 AM PST Researchers have found an explanation for why very little nitrogen could previously be accounted for in the nebulous covering of comets: the building block for life predominantly occurs in the form of ammonium salts, the occurrence of which could not previously be measured. The salts may be a further indication that comet impacts may have made life on Earth possible in the first place. |
Addressing global warming with new nanoparticles and sunshine Posted: 21 Jan 2020 08:29 AM PST Harvesting sunlight, IBS scientists reported a new strategy to transform carbon dioxide (CO2) into oxygen (O2) and pure carbon monoxide (CO) without side-products in water. This artificial photosynthesis method could bring new solutions to environmental pollution and global warming. |
'Ancient' cellular discovery key to new cancer therapies Posted: 21 Jan 2020 08:29 AM PST Researchers have uncovered a metabolic system which could lead to new strategies for therapeutic cancer treatment. A team has found a link between a metabolic system in a yeast, and now mammals, which is critical for the regulation of cell growth and proliferation. |
Platypus on brink of extinction Posted: 21 Jan 2020 08:29 AM PST New research calls for national action to minimize the risk of the platypus vanishing due to habitat destruction, dams and weirs. |
TB bacteria survive in amoebae found in soil Posted: 21 Jan 2020 08:29 AM PST Scientists have discovered that the bacterium which causes bovine TB can survive and grow in small, single-celled organisms found in soil and dung. It is believed that originally the bacterium evolved to survive in these single-celled organisms known as amoebae and in time progressed to infect and cause TB in larger animals such as cattle. |
Insecticides are becoming more toxic to honey bees Posted: 21 Jan 2020 08:29 AM PST Researchers discover that neonicotinoid seed treatments are driving a dramatic increase in insecticide toxicity in U.S. agricultural landscapes, despite evidence that these treatments have little to no benefit in many crops. |
Arctic sea ice can't 'bounce back' Posted: 21 Jan 2020 08:29 AM PST Arctic sea ice cannot 'quickly bounce back' if climate change causes it to melt, new research suggests. |
