Mammals metabolize some pesticides to limit their biomagnification
The concentrations of many historically used, and now widely banned, pesticides and other toxic chemicals—called legacy contaminants—can become magnified in an animal that eats contaminated food; however, ...
A global view of oceanic phytoplankton
University of Maine oceanographer Ivona Cetinic is participating in a NASA project to advance space-based capabilities for monitoring microscopic plants that form the base of the marine food chain.
Rare byproduct of marine bacteria kills cancer cells by snipping their DNA
(Phys.org) —Yale University researchers have determined how a scarce molecule produced by marine bacteria can kill cancer cells, paving the way for the development of new, low-dose chemotherapies.
Study reveals strong links between Antarctic climate, food web
A long-term study of the links between climate and marine life along the rapidly warming West Antarctic Peninsula reveals how changes in physical factors such as wind speed and sea-ice cover send ripples ...
The end of traffic jams? Dutch test new system
Researchers in the Netherlands will next year test a GPS navigation system aimed at preventing the international curse of motorway traffic jams by telling drivers which lane to move to.
The final nail in the Jurassic Park coffin: Next generation sequencing reveals absence of DNA in sub-fossilized insects
It is hardly possible to talk about fossil insects in amber without the 1993 movie Jurassic Park entering the debate. The idea of recreating dinosaurs by extracting DNA from insects in amber has held the ...
Turning toxic by-product into biofuel booster: Engineered enzyme increases output of alkanes
Scientists studying an enzyme that naturally produces alkanes—long carbon-chain molecules that could be a direct replacement for the hydrocarbons in gasoline—have figured out why the natural reaction ...
Paint-on plastic electronics: Aligning polymers for high performance
Semiconducting polymers are an unruly bunch, but University of Michigan engineers have developed a new method for getting them in line that could pave the way for cheaper, greener, "paint-on" plastic electronics.
Combating bacterial biofilm formation with titanium encrusted with gold nanoparticles
Bacteria love to colonize surfaces inside your body, but they have a hard time getting past your rugged, salty skin. Surgeries to implant medical devices often give such bacteria the opportunity needed to ...
Team uses solar-powered proteins to filter harmful antibiotics from water
(Phys.org) —New research, just published, details how University of Cincinnati researchers have developed and tested a solar-powered nano filter that is able to remove harmful carcinogens and antibiotics ...
Molecule's carbon chain length affects oxygen's departure in key reaction for building bio-fuels
(Phys.org) —In a maze of blindingly complex reactions that snap oxygen atoms off cellulose or other bio-sources to create energy-dense fuel, the starting molecule's size has a curious effect. If the oxygen-rich ...
Researchers calculate human trophic level for first time
Ocean microbes display remarkable genetic diversity
The smallest, most abundant marine microbe, Prochlorococcus, is a photosynthetic bacteria species essential to the marine ecosystem. An estimated billion billion billion of the single-cell creatures live i ...
Overfishing in the English Channel leaves fisherman scraping the bottom of the barrel
Decades of overfishing in the English Channel has resulted in the removal of many top predators from the sea and left fishermen 'scraping the barrel' for increasing amounts of shellfish to make up their catch.
