Understanding biases in epidemic models important when making public health predictions

...lighting what 'may happen' if we don't pay careful attention to the inherent assumptions in the models that we fit to data," said Wearing. "The key point is that uncertainty about the latent and infectious period distributions should be taken into account when making quantitative predictions for public health ...

Discovery of an American salamander where it shouldn't be: Korea

...he salamander as a plethodontid and drew it to the attention of Wake. Wake and post-doctoral fellows David R. Vieites and Ronald M. Bonett of UC Berkeley's Museum of Vertebrate Zoology and Department of Integrative Biology performed anatomical comparisons and a molecular phylogenetic analysis to determine the ...

Study shows humans have ability to track odors, much like bloodhounds

...heir brains showed that the brain is set up to pay attention to the difference between what the left and right nostrils sense, much the way it can localize sounds by contrasting input from the ears. "It has been very controversial whether humans can do egocentric localization, that is, keep their head motionl...

Research on antibiotics receives historical recognition

...but it was not until late 1930s that he turned his attention to the searching for microbes that attacked other microbes. Waksman received the Nobel Prize for physiology or medicine in 1952 for "ingenious, systematic and successful studies of the soil microbes" that led to the discovery of streptomycin. He die...

Cancer related gene p53 not regulated as indicated by previous tissue culture research

...ssor Geoffrey M. Wahl. "This new study focuses our attention on the network of regulators of p53 and how they are regulated." "This study caused a big shift in how we think about p53," explains Salk scientist and first author Kurt Krummel. "You have to look at all interacting partners because after all, modif...

Discovery of New Dopamine Action May Yield Alternative Psychiatric Drugs

...concentrations of dopamine underlie schizophrenia, attention deficit hyperactivity disorder and other psychiatric conditions. The findings therefore provide new research avenues to understand and potentially manage such dopamine-related human disorders, the researchers said. "We've thought that neurotransmitt...

High fidelity keeps human DNA assembly line humming

...function. In the world of molecular biology, much attention has been given to how RNA is made. Burton explains that it is similar to an industrial assembly line, with DNA being a conveyer belt to load building blocks, or bases, called nucleoside triphosphates (NTPs) to hook up with a growing strand of RNA. B...

15 generations of untrained jocks, couch potatoes show big physiological adaptations

...ystems, the group of researchers are turning their attention to identify the various genes involved that provide the underlying signal for "why" some subjects become more athletic, while others are couch potatoes. This effort will include looking for genes and/or signaling mechanisms that prompt the initial s...

Primates on the brink

...ges to the list from 2002 reflect a desire to draw attention to other endangered primates. For example, Miss Waldron's red colobus, which has gone decades without a live sighting, was replaced by the Bioko red colobus to show that other colobus species also are under extremely grave threat. "All evidence tell...

Structure-building cell signals also may influence learning and memory

...been intensively studied for many years, with most attention being paid to its maintenance of the cell's skeletal structure during development." Once the biochemical pathway was determined, the researchers then looked at whether ephrin truly increased endocytosis in cells that were not altered genetically. Us...

Distributed Basic Local Alignment Search Toolkit (W.ND-BLAST)

...ghout North America are increasingly turning their attention to water as a source of nosocomial (hospital-acquired) infection as a result of recognition of the prevalence and risks posed by waterborne pathogens. However, he noted, there is a great deal more to be done. He stated that the infectious disease co...

New strategies to reduce hospital-aquired infections

Oceans more vulnerable to agricultural runoff than previously thought, study finds

... on the gulf, the Stanford scientists turned their attention to one of Mexico's most productive coastal farming regions-the Yaqui River Valley, which drains into the gulf. "The Yaqui Valley agricultural area is 556,000 acres [225,000 hectares] of irrigated wheat," Matson said. "The entire valley is irrigated ...

One gene links newborn neurons with those that die in diseases such as Alzheimer's

...neuronal death," says Nottebohm. "This study draws attention to the replaceable neurons of adult brain as a wonderful model system in which to study changes in genomic expression related to learning, aging and neurodegeneration, in addition to those that are related to the choreography of replacement itself." ...

Scientists journey to southern Africa to unravel the secret world of elephant communication

Live vaccines more effective against horse herpes virus

... been exposed to equine herpes virus, with special attention paid to those stabled at Churchill Downs since May 1. In some 90 percent of infected horses, equine herpes virus type 1 (EHV-1) leads to a mild upper respiratory infection with fever, nasal discharge and fatigue for a day or two. The virus can also ...

Shift of weather patterns necessitates rethinking of reforestation methods

...r said. "Doing everything right" meant meticulous attention to care of the bare root seedlings, soil moisture at planting time, attention to weather conditions and planting techniques, Taylor said. If everything is done correctly, contai...

Youth With HIV Take More Risks After New Meds Introduced

...r, "these findings indicate the need for continued attention to the issue of sexual risk and the impact of HAART," Lightfoot says. The new study also suggests the lives of some HIV-positive teens have not improved with HAART. Lightfoot and colleagues found that the post-HAART group was in worse health, more l...
