Microfluidic chip helps solve cellular mating puzzle

...s -- because what we find out in yeast often holds true for humans as well. In this study, we looked at how yeast cells signal one another when they want to merge, engaging in a type of mating behavior. Human cells ‘talk?to one another in a similar way, and it’s important to understand this process." Y...

Long-lived deep-sea fishes imperiled by technology, overfishing

...f the time," Heppell said. "That isn't necessarily true anymore." Heppell is a faculty member in the Department of Fisheries and Wildlife at Oregon State, where she studies fish dynamics, populations and life cycles. The deep-sea fishes are among the hardest to study for obvious reasons, she said, and ...

Rewarding fat rats

... reflect the work of a team, and that is certainly true in my case. I have been privileged to have terrific trainees and faculty colleagues as research collaborators, many of whom have been supported by NSERC scholarships and grants." In their studies of food reward, Shizgal's team investigated the rol...

Genes and biomarkers that allow doctors to choose the right therapy for the right patient

...o two people are exactly alike, and the same holds true for any two cancers. Now, researchers have the tools and the knowledge to help predict how individuals will respond to cancer therapies, enabling them to create more effective therapies for individual cancers ?personalized medicine. At the 2007 Annu...

Scientists discover new, readily available source of stem cells

Type of stem cell found to reside in transplanted lungs

...ssues of the adult lung ?something that might hold true for other organ systems as well. "Potentially the most important outcome of our finding is that it could lead to an understanding about therapeutic options using MSCs that reside in adult organs," Lama continues. "These lung-derived cells are diff...

Study calculates patient time costs associated with cancer care

...costs, "we know we have greatly underestimated the true cost of the disease," they write. Nevertheless, Kessler and Ramsey conclude, new treatments that reduce patient time costs should be encouraged, and manufacturers should quantify these benefits and then convey them to patients, providers, and health ...

It's OK for men with high blood pressure to have a drink or two, new study finds

...hol can increase blood pressure, would the same be true for men who have high blood pressure? The new study, published in the January 2, 2007, issue of Annals of Internal Medicine, is based on data from the Health Professionals Follow-Up Study. It found that men with high blood pressure can have one or...

Imaging pinpoints brain regions that 'see the future'

...es in a specific future scenario. "The same is true with very small children -- they don't remember particularly what happened last month and they can't really tell you much of anything about what they envision happening next week. This is also the case with suicidally depressed people. So, there's th...

Nanotextured implant materials: blending in, not fighting back

...plants in live animals. If the same behavior holds true for materials placed in the body, the rapid growth of endothelial cells would help the implants to integrate quickly into existing blood vessels, provoking less immune response and a longer-lasting repair. ...

Major gene study uncovers secrets of leukemia

...at the approach used provides a lower limit of the true frequency of these mutations, since not every gene in this pathway could be accurately analyzed using this methodology," Downing said. The mutations identified in "PAX5," "EBF" and "Ikaros" are likely to directly contribute to this block in norma...

In obesity, brain becomes 'unaware' of fat

...ot aware that the body is obese.? If the same is true in humans, he added, people may be consciously aware that they are overweight, but “that’s different from the homeostatic circuitry being aware.? The new results also bolster evidence that a suppressor called SOCS-3 may be responsible for the loss ...

Studies force new view on biology of flavonoids

... scientists say. However, Frei said, it’s also true that such mechanisms require only relatively small amounts of flavonoids to trigger them ?conceptually, it’s a little like a vaccine in which only a very small amount of an offending substance is required to trigger a much larger metabolic response. ...

In young mice, gregariousness seems to reside in the genes

That may well be true for many adult animals, but in a groundbreaking study researchers from the University of Wisconsin-Madison have found evidence that social interactions among young mice result from basic motivations to be with one another. What's more, the researcher...

Do fruit flies have free will?

Free will and true spontaneity exist ?in fruit flies. This is what scientists report in a groundbreaking study in the May 16, 2007 issue of the open-access journal PLoS ONE. "Animals and especially insects are usually seen as complex robots which only respond to exter...

Scientists seek useful traits in wild cottons

...and results in a lot of damage to those first four true seedling leaves," he said. "We measure the leaf damage, identify cottons that show thrips resistance and subject those to further tests." Sheehan raises Lygus bugs, a secondary pest of cotton, and confines their feeding to certain parts of c...

First demonstration of new hair follicle generation in an animal model

(The liver can regenerate large portions, but it is not de novo regeneration; some of the original liver has to remain so that it can regenerate.) In this study, researchers found that wound healing in a mouse model created...
