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.

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. |
First detailed electronic study of new nickelate superconductor finds 3D metallic state Posted: 21 Jan 2020 08:30 AM PST Unlike cuprates -- the first known class of unconventional superconductors -- the new nickelates are inherently metallic, sharing electrons with intervening layers of rare earth material to create a 3D metallic state. This is an entirely new type of ground state for transition metal oxides such as cuprates and nickelates, researchers said. It opens new directions for experiments and theoretical studies of how superconductivity arises and how it can be optimized in this system and possibly in other compounds. |
Art speaks for itself and makes hearts beat faster Posted: 21 Jan 2020 08:30 AM PST Information about an artwork has no effect on the aesthetic experience of museum visitors. The characteristics of the artwork itself have a much stronger impact on observers. |
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. |
Record-breaking terahertz laser beam Posted: 21 Jan 2020 08:30 AM PST Terahertz radiation is used for security checks at airports, for medical examinations and also for quality checks in industry. However, radiation in the terahertz range is extremely difficult to generate. Scientists have now succeeded in developing a terahertz radiation source that breaks several records: it is extremely efficient, and its spectrum is very broad -- it generates different wavelengths from the entire terahertz range. This opens up the possibility of creating short radiation pulses with extremely high radiation intensity. |
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. |
