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.
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.
Chemists create 'assembly-line' for organic molecules
(Phys.org) —Scientists at the University of Bristol have developed a process where reagents are added to a growing carbon chain with extraordinary high fidelity and precise orientation, thereby controlling ...
Loss of large predators tips ecosystem balance, according to study
A new study has linked the size of predators atop a food chain with the ecological chain reaction triggered when they leave the head of the table.
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 ...
Before an asteroid wiped out the dinosaurs, Earth experienced a short burst of intense volcanism
Sixty-six million years ago, an asteroid more than five miles wide smashed into the Earth at 70,000 miles per hour, instantly vaporizing upon impact. The strike obliterated most terrestrial life, including ...
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
Origin of the Eukaryotic cell: Part II - Cytoskeleton, membranes, and beyond
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 ...
Calcium loss turning lakes to 'jelly'
New research on a number of Canadian lakes show that historical acid deposits as a result of industry have greatly reduced calcium levels in the water - dramatically impacting populations of calcium-rich ...
New self-stretching material developed
Although most materials slightly expand when heated, there is a new class of rubber-like material that not only self-stretches upon cooling; it reverts back to its original shape when heated, all without physical manipulation.
Nanoparticles accumulate quickly in wetland sediment
(Phys.org) —A Duke University team has found that nanoparticles called single-walled carbon nanotubes accumulate quickly in the bottom sediments of an experimental wetland setting, an action they say could ...
