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.
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 ...
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
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 ...
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 ...
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.
Seeing is bead-lieving: Scientists create model 'bead-spring' chains with tunable properties
Rice University researchers are using magnetic beads and DNA "springs" to create chains of varying flexibility that can be used as microscale models for polymer macromolecules.
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 ...
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 ...
All the world's oceans have plastic debris on their surface
The Malaspina Expedition, led by the Spanish National Research Council, have demonstrated that there are five large accumulations of plastic debris in the open ocean that match with the five major twists ...
Marine bacteria are natural source of chemical fire retardants
Researchers at the University of California, San Diego School of Medicine have discovered a widely distributed group of marine bacteria that produce compounds nearly identical to toxic man-made fire retardants.
Structures made of polymer chains allow organic catalysts to work in water
Organic catalysts are essential for a number of industrial applications, but their inability to work within the same system or in water means that their efficiency is somewhat limited. Researchers from the ...
