Molecular thermometers on skin cells detect heat and camphor

...rain, its distribution raised some doubts. Despite expectations that temperature sensors be present in sensory neurons innervating the skin, TRPV3 protein was found in actual skin cells (keratinocytes) and not in the neurons. Now, in the latest issue of the journal Science, the team is reporting definitive evide...

Research casts doubt on circulating stem cells

...ieves that it is necessary to dampen the very high expectations held by some colleagues: "In my view, many of the studies using bone marrow-derived stem cells have so far been interpreted over-optimistically." The experiments with green-fluorescent nerve cells would seem to be one such case: "The bone marrow-deri...

Chernobyl: The true scale of the accident

...reas have died of natural causes. Also, widespread expectations of ill health and a tendency to attribute all health problems to radiation exposure have led local residents to assume that Chernobyl related fatalities were much higher than they actually were. What diseases have already occurred or might occur in ...

Hopkins scientists show hallucinogen in mushrooms creates universal 'mystical' experience

...f adverse side-effects and the likelihood that the expectations of getting the test drug or the placebo would influence subjects' perceptions. To lessen the former, each subject met several times, before drug sessions began, with a reassuring "monitor," a medical professional experienced in observing drug stud...

Newborn screening can cause unnecessary parental stress

...sbren believes a positive test result can increase expectations of illness even when it is later found to be in error. "We're not sure why ?maybe it feeds into a general nervousness as new parents," she speculates. "But our results also show that parental stress was greater when families didn't have adequate info...

Development of gene therapy

...r type of therapy, has given rise not only to high expectations of treatment success but also great concerns regarding health risks. Since the Deutsche Forschungsgemeinschaft (German Research Foundation, DFG) issued its first memorandum in 1995, this field of research has developed enormously. Wide-ranging expe...

Trying to control pain can be a double-edged sword, say scientists

...p the painful stimulation subjects with no control expectations were better at activating this brain region than those with a strong control belief. The findings support the practice of "acceptance-based therapy" whereby doctors focus on training patients to cope with the pain rather than attempting to make th...

One species, many genomes

... extent of the genetic differences far exceeds the expectations for such a streamlined genome, as the scientists write in this week’s edition of Science magazine. Arabidopsis plants from different geographical origins differ in many traits (the background shows schematically sequence variation in the DNA of th...
