Marine mammals are on the frontline of failing ocean health

...ska as a Laboratory One of the most challenging aspects of understanding how humans impact ocean health is the fact that so many environmental changes are going on at the same time. Climate change is already having an effect on the spread of disease and pollutants, adding yet another twist to the story. ...

Typhoid fever led to the fall of Athens

...niversity of Athens says: "Studying the historical aspects of infectious diseases can be a powerful tool for several disciplines to learn from. We believe this report to be of outstanding importance for many scientific fields, since it sheds light to one of the most debated enigmas in medical history." ...

New compound stops brain cell degeneration in Alzheimer's disease

... been implicated so directly. There are three key aspects of the report, Watterson said. "First, a novel compound for development into a new class of Alzheimer's disease therapeutics that target disease has been described. Second, an innovative approach was used for the rapid and cost-effective discovery o...

Pittsburgh researchers discover that certain chemicals in the blood may indicate brain injury

...ble cases of missed SBS. "One of the interesting aspects of the study was that in many of the children who were ultimately identified as having SBS, the caretaker who brought the child to the hospital for evaluation did not know that the child had been shaken," said Dr. Berger. "It is so important for phys...

Clock molecule's sensitivity to lithium sheds light on bipolar disorder

..., which also provide insight into clock-controlled aspects of metabolism, are reported in this week's issue of Science. "We're interested in the internal control of metabolism because feeding behavior is on a daily cycle, and hormonal activities that regulate this are circadian," says senior author Mitch La...

Born with a love of speech

...le a chorus of Martians, closely mimic the melodic aspects of speech. They also contain a fundamental frequen...wborns discriminate between just the low frequency aspects (those that are heard across the womb) of their speech analogue and non-sense words? If they showed ...

Engineered mouse mimics cognitive aspects of schizophrenia

...t tests of cause-effect relationships for specific aspects of the disease, such as some of the cognitive deficits," they concluded. "We here have been able to introduce genetically a single molecular alteration in a restricted and regulated fashion and to study its behavioral and physiological consequences."...

Study finds evolution doesn't always favor bigger animals

...adapt to a warmer world? Size correlates with many aspects of the biology of an animal so changes in size are likely to translate into substantial ecological changes. A better prediction of the biological effects of future global change requires that, among other things, we understand how climate change shap...

Why nerve cells work faster than the theory allows

...ansmitted well, slow signals are suppressed". Both aspects of the initiation of the action potential play different roles. The large variability of the threshold potentials allows the cells to ignore slowly varying stimuli. The cells continuously increase their threshold so that in many cases no impulse is i...

HortResearch science reveals the natural potential of apples

...rets to discovering how gene function controls all aspects of fruit development, including taste, colour, vitamin content and even how fruit fight plant diseases. Fruit breeders can then use this information to create new apple varieties, tailored to suit consumer tastes, health requirements, and the demand...

Neuroscientists discover new cell type that may help brain maintain memories of smells

... recognizing the odor begins. One of the puzzling aspects of olfaction is how our perception of an odor can evolve over multiple sniffs. Because of their unique ability to maintain their activity between sniffs, Blanes cells may provide the missing link needed to answer this critical question. While ther...

Insects that produce males from unfertilized eggs reveal a surprising cellular feat

... to form," Ferree said. One of the most striking aspects of this mechanism is the large number of accessory nuclei and centrosomes that form in the developing eggs of these Hymenopteran insects. "You only need two centrosomes, and they make hundreds of them. So they go through a lot of work to make a male...

Penguins waddle but they don't fall down, UH researchers say

...we simply waddle, chances are we'll fall, but some aspects of a penguin's wobble could be very beneficial. "We can envision a scenario where elderly may be able to put their walkers or canes down because they've learned to make the same adjustments in their walking patterns," Kurz said. "This research may ...

Oops! Researchers publish new findings on the brain's response to costly mistakes

...nxiety or fear about errors or failures in certain aspects of everyday life, with repetitive patterns of behavior to ward off or prevent such events. The new research, published in the Journal of Neuroscience, involved 12 healthy adults who had their brains scanned using a powerful functional MRI (fMRI) im...

Leave it to salmon to leave no stone unturned

...he disturbance from spawning impacts virtually all aspects of stream ecology," he says. The female salmon, of course, isn't concerned about all that. She simply wants to lay her eggs in a nice, gravel-bottom bowl that's free of fine sediments that can smother them. But consider the efforts of the grand dam...

Salk researchers make fast strides towards understanding how our body controls walking

...t and understanding how they control the essential aspects of walking should put us in a better position to design treatments or implants that restore or activate these pathways," said Martyn D. Goulding, Ph.D., a professor in the Molecular Neurobiology Laboratory. The Salk research team ?led by Goulding?pu...

New licensing agreement to maximize AIDS drug development

...ement. We have collaborated for many years on all aspects of our microbicide development programs, and we have a deep respect for each other's knowledge and expertise. With CONRAD, we feel we have a capable and experienced partner to work with us toward approval of these critically important products," sai...

Vital ocean prey play active role in environment

...of the best-studied organisms of the open sea, key aspects of their life cycle have remained murky. Understanding krill is important because they are vital prey for fish, birds, and marine mammals, yet they are vulnerable to fishing pressure and environmental change. In the February 2006 issue of BioScience...
