Climate change forces a rethinking of mammoth Everglades restoration plan
In 1948, work got underway in the Florida Everglades on a public works project hailed as the nation's largest, aimed at reigning in once and for all the mighty river of grass that once spanned much of the peninsula......»»
For sheds in wildfire zones, researchers determine how close is too close to home
It may seem obvious that a flammable structure placed next to a house poses a fire hazard, especially if it's in a wildfire-prone community. What has been less clear, though, is how far away these items, such as sheds, need to be located to significa.....»»
Chemists develop a new class of antibiotics to fight resistant bacteria
Health professionals are in urgent need of new antibiotics to tackle resistant bacteria. Researchers at the University of Zurich and the company Spexis have now modified the chemical structure of naturally occurring peptides to develop antimicrobial.....»»
Study demonstrates one of the world"s fastest electron microscopes in action
Electron microscopes give us insight into the tiniest details of materials and can visualize, for example, the structure of solids, molecules or nanoparticles with atomic resolution. However, most materials in nature are not static. They constantly i.....»»
Deep learning helps in global estimation of phytoplankton pigment concentrations
The community structure of phytoplankton can reflect changes in marine environment and help us understand driving factors behind ecological evolution. Quantifying pigment concentration in phytoplankton is crucial for comprehensive assessment of taxon.....»»
Diablo 4 review: A bold new step for hack-n-slash RPGs

Examining networks in the dog brain provides further insights into mammalian evolution
A study on canine brain networks reveals that during mammalian brain evolution, the role of the cingulate cortex, a bilateral structure located deep in the cerebral cortex, was partly taken over by the lateral frontal lobes, which control problem-sol.....»»
Predicting policy choices via network structure
Indonesia is the biggest palm oil producer in the world, with the U.S. Department of Agriculture crediting it with a nearly 60 percent share of global production. The versatility of palm oil—it is used in cosmetics, food products, detergents—is a.....»»
In situ investigation of the structure-activity correlation for carbon dioxide electrolysis in SOECs
Solid oxide electrolysis cells (SOECs) provide a practical solution for direct conversion of CO2 to chemicals; however, an in-depth mechanistic understanding of the dynamic reconstruction of active sites for perovskite cathodes during CO2 electrolysi.....»»
What was behind Australia"s potato shortage? Wet weather and hard-to-control diseases
,If you've been into a fish and chip shop in the last 12 months, you may well have seen a notice tacked to the wall about the impact of the potato shortage. Supermarkets, too, slapped temporary limits on frozen chip purchases......»»

Publication of the first global macrogenetic map of marine habitat-forming species
Species known as marine habitat-forming species —gorgonians, corals, algae, seaweeds, marine phanerogams, etc.— are organisms that help generate and structure the underwater landscapes. These are natural refuges for other species, and provide bio.....»»
Large-scale long terminal repeat insertions found to produce a significant set of novel transcripts in cotton
TEs (transposable elements), especially LTRs, are known to play an important role in determining the basic genome structure and influencing the expression of functional genes. Insertion of TE or LTR fragments may also create novel transcription start.....»»
