Communication often fumbled during patient hand-offs in hospital

Sat, 13 Mar 2010 04:24:36 GMT

― Communication often fumbled during patient hand-offs in hospital [sciencedaily.com]
As shifts change in a hospital, outgoing physicians must "hand off" important information to their replacements in a brief meeting. But a new study of this hand-off process finds that the most important information is not fully conveyed in a majority of cases, even as physicians rate their communication as successful.

Plants discover the benefits of good neighbors in strategy against herbivores

Sat, 13 Mar 2010 04:24:34 GMT

― Plants discover the benefits of good neighbors in strategy against herbivores [sciencedaily.com]
Scandinavian scientists have discovered that a species of tree defends itself from herbivore attack by using chemicals emitted by neighboring plants. The study reveals how species of Birch tree absorb chemical compounds from neighboring Marsh tea plants, Rhondodendron tomentosum, in a unique "defense by neighbor strategy."

Exploiting the architecture of cancers may lead to their destruction

Sat, 13 Mar 2010 04:24:33 GMT

― Exploiting the architecture of cancers may lead to their destruction [sciencedaily.com]
To grow larger, solid tumors require a network of blood vessels to nourish them. Chemotherapy exploits these vessels to deliver toxic drugs, but is inefficient if the drugs cannot pass quickly enough from the bloodstream into the tumor. A new study describes a way of transiently making the tumor blood vessels leakier, allowing more efficient drug uptake. This work may ultimately enhance delivery of chemotherapies into tumor tissue.

Sony Challenges Wiimote With PlayStation Move

― Nintendo: We’d be “embarrassed” if we were Sony or Microsoft [inquisitr.com]
Sony and Microsoft will both release motion-sensing controllers this year, for the PlayStation 3 and Xbox 360 respectively. Let’s face it: by bringing motion-sensing games to their consoles, S & M are copying Nintendo’s Wii, or at least being heavily influenced by it, if you were feeling kind. Thing is, they don’t seem too fazed about outright nabbing Nintendo’s idea. Actually, they’re pretty shameless, and now Nintendo bossman Reggie Fils-AIme has stepped in to say they should both be...

The usual excuse of "lack of time" for not doing enough exercise is blown away by new research. The study adds to the growing evidence for the benefits of short term high-intensity interval training (HIT) as a time-efficient but safe alternative to traditional types of moderate long term exercise. Astonishingly, it is possible to get more by doing less!

A new beat in heart research

― A new beat in heart research [esciencenews.com]
Sudden Cardiac Arrest syndrome (SCA) is poorly understood, but it's a real danger for the otherwise young and healthy. For no apparent reason, the heart suddenly stops beating, and without treatment death may follow within minutes. It's why some athletes drop dead on the track and why a young man, without any warning, suddenly dies while sitting at his desk. SCA accounts for approximately 300,000 deaths per year in the U.S.

Blind scorpions that live in the stygian depths of caves are throwing light on a long-held assumption that specialized adaptations are irreversible evolutionary dead-ends. According to a new phylogenetic analysis of the family Typhlochactidae, scorpions currently living closer to the surface (under stones and in leaf litter) evolved independently on more than one occasion from ancestors adapted to life further below the surface (in caves). The research, currently available in an early online...
