Biological treatment plus ozone can reduce the amount of sludge coming from wastewater treatment plants by a factor of ten
View ArticleRobots learn to pick up oddly shaped objects
(Phys.org) -- When Cornell engineers developed a new type of robot hand that could pick up oddly shaped objects it presented a challenge: It was easy for a human operator to choose the best place to...
View ArticleTU Delft's promising water-treatment technologies combined
Thanks to research by Mari Winkler, it should now be possible to integrate two successful TU Delft technologies for the treatment of waste water with bacteria, Nereda and Anammox, into a single plant....
View ArticleResearchers identify critical operating temperature of catalytic converters
(Phys.org)—Catalytic converters work poorly if they have not yet warmed up. Tiny metal particles in a catalytic converter require a minimum temperature to function efficiently. At the Vienna University...

(Phys.org) —The team operating NASA's Curiosity Mars rover has selected a second target rock for drilling and sampling. The rover will set course to the drilling location in coming days.
View ArticleEarthworms could help scientists 'dig' into past climates
A team of UK researchers believe earthworms could provide a window into past climates, allowing scientists to piece together the prevailing weather conditions thousands of years ago.
View ArticleA protein provides stress relief for cells
German researchers have shown a new mechanism via which cells defend themselves against stress. Dr. Kathrin Thedieck and Birgit Holzwarth from the Institute of Biology III and the Cluster of Excellence...

A newly developed recycling process could make landfill sites filled with old shoes a thing of the past.
View ArticleThe plant that only grows when the going's good
Scientists have identified a new mutant plant that accumulates excessive amounts of starch, which could help to boost crop yields and increase the productivity of plants grown for biofuels.
View ArticleNew trick found for how cells stay organized
Organization is key to an efficient workplace, and cells are no exception to this rule. New evidence from Johns Hopkins researchers suggests that, in addition to membranes, cells have another way to...
View ArticleJumping genes have essential biological functions
"Alu" sequences are small repetitive elements representing about 10% of our genome. Because of their ability to move around the genome, these "jumping genes" are considered as real motors of evolution....
