Radar altimetry revolutionises the study of the ocean

...r oceanographic community. Although it took over a decade for its full impact to be realised, its accomplishments have been so great that it is credited with having revolutionised the field of physical oceanography. In honour of altimetry, oceanographers, glaciologists, hydrologists and geodesists from ar...

Rice University researchers create 'nanorice'

...PR) nanosensor yet devised. Research over the past decade has shown that nanoscale objects can amplify and focus light in ways scientists never imagined. The "how" of this involves plasmons, ripples of waves in the ocean of electrons that flow constantly across the surfaces of metals. When light of a specif...

Chemists report progress in quest to use hydrogen as fuel for cars and electronic devices

...tore hydrogen at ambient temperatures (0V45aC). "A decade ago, people thought methane would be impossible to store; that problem has been largely solved by our MOF materials. Hydrogen is a little more challenging than methane, but I am optimistic." Yaghi, 41, has reason to be optimistic since only a handful...

Companies license real-time pathogen detection technology developed at Kent State, NEOUCOM

...cal thing we can do as microbiologists in the next decade is to come up with technology that will identify microorganisms in real time. We have created a biosensor a detector for bacteria and viruses that will change the way in which detection and identification of microorganisms is done," said Dr. Woolve...

Astronomer announces shortlist of stellar candidates for habitable worlds

...s. Astronomers have found evidence during the past decade for dozens of planets around nearby stars by studying how an object's gravity affects the orbit of the parent star. Virtually all of the discovered planets are gas giants like Jupiter and are presumed to be inhospitable to life. There have been hint...

"Recent studies we've conducted have shown that thin film nitinol can be used to cover ste...

Eating less fat may lower breast-cancer risk, have little impact on colon-cancer, heart-disease risk

UMaine teams with fishermen to study affects of trawling on seafloor ecology

...ars, Watling estimates that it will take roughly a decade for the surface-dwelling organisms to reestablish themselves, but cautioned that a full recovery of the habitat would take much longer. "I am pretty firmly convinced that if the groundfishing industry doesn't soon begin to undertake measures to cons...

Mutation in brain cells of descendants of Abraham Lincoln suggest he suffered from movement disorder

...he joint finding of the SCA5 mutation comes over a decade after initial speculation that Lincoln might have suffered from Marfan disease. People with this inherited disorder are often tall and thin and can commonly have slender, tapering fingers. The identification of the Marfan gene at Hopkins (Nature 352,...

Scientists find genetic pathway that could lead to drugs for kidney disease

...ven though polycystin-1 was discovered more than a decade ago, its function has remained unknown. In this study, Weimbs and his colleagues discovered that, under normal conditions, the polycystin-1 keeps certain parts of the cell localized in the cilia and away from the nucleus. These parts of the cell ar...

U of MN researchers identify ataxia gene

She and her colleagues John Day, M.D., Ph.D., University of Minnesota, and Larry Schut, M.D., CentraCare Clinic in St. Cloud, Minn., examined and collected DNA samples from more than 300 Lincoln family members who live across the country, track...

The results, said co-author Ruby Leung, a PNNL laboratory fellow, "strongly suggest that increasing aerosol concentrations (particles, mainly soot and sulfur, that pollute the air) in th...

The giant protein titin helps build muscles

...y. The latest study, which arises from more than a decade of collaborative research by the Wilmanns and Gautel teams, gives a solution to how this might happen. Peijian Zou and Nikos Pinotsis from the Wilmanns lab obtained crystals of parts of the titin molecule bound to another protein, called telethonin. ...

New data show Ferriprox is more efficacious than deferoxamine

Until recently, the only chelator available was DFO, a drug that must be injected under the skin for 8-12 hours, for 5-7 nights per week. Ferriprox, the f...

An elephant tail

Goals include preserving habitats, protecting corridors and minimizing conflicts with humans. In the new study, Cerling first calculated the rate of tail hair growth for the seven elephants s...

Tiny pikas seem to be on march toward extinction in Great Basin

"We might be staring pika extinction in the Great Basin, maybe in Yosemite, too, right in the face. Today, the Great Basin pika is totally isolated on separated mountai...

Max Planck researchers make a breakthrough in plant stem cell research

However, until now, it was unclear how hormones and regulatory genes, such as WUSCHEL work together to maintain t...

Genetic testing still smart choice, despite uncertainties

...on genetic diagnosis has been used for more than a decade to screen embryos for hereditary diseases such as Down syndrome and other abnormalities. To do this, one cell from an eight-cell embryo is extracted and examined for chromosomal defects. However, as many as half these embryos spawn cells with differ...
