Plasma treatment zaps viruses before they can attack cells
2011-12-19
Adenoviruses can cause respiratory, eye, and intestinal tract infections, and, like other viruses, must hijack the cellular machinery of infected organisms in order to produce proteins and their own viral spawn. Now an international research team made up of scientists from Chinese and Australian universities has found a way to disrupt the hijacking process by using plasma to damage the viruses in the laboratory environment, before they come into contact with host cells.
The researchers prepared solutions containing adenoviruses and then treated the samples with a low-temperature ...
New device creates lipid spheres that mimic cell membranes
2011-12-19
Opening up a new door in synthetic biology, a team of researchers has developed a microfluidic device that produces a continuous supply of tiny lipid spheres that are similar in many ways to a cell's outer membrane. "Cells are essentially small, complex bioreactors enclosed by phospholipid membranes," said Abraham Lee from the University of California, Irvine. "Effectively producing vesicles with lipid membranes that mimic those of natural cells is a valuable tool for fundamental biology research, and it's also an important first step in the hoped-for production of an artificial ...
New system may one day steer microrobots through blood vessels for disease treatment
2011-12-19
Microscopic-scale medical robots represent a promising new type of therapeutic technology. As envisioned, the microbots, which are less than one millimeter in size, might someday be able to travel throughout the human bloodstream to deliver drugs to specific targets or seek out and destroy tumors, blood clots, and infections that can't be easily accessed in other ways.
One challenge in the deployment of microbots, however, is developing a system to accurately "drive" them and maneuver them through the complex and convoluted circulatory system, to a chosen destination. ...
Close family ties keep microbial cheaters in check, study finds
2011-12-19
Any multicellular animal, from a blue whale to a human being, poses a special challenge for evolution.
Most of the cells in its body will die without reproducing; only a privileged few will pass their genes to the next generation.
How could the extreme degree of cooperation required by multicellular existence actually evolve? Why aren't all creatures unicellular individualists determined to pass on their own genes?
Joan Strassmann and David Queller, evolutionary biologists at Washington University in St. Louis, provide an answer in this week's issue of the journal ...
Following the crowd supports democracy
2011-12-19
This press release is available in German.
From shoals of fish to human society: social organisms need to make collective decisions. And it is not always the majority that prevails. In some cases, a small, resolute group may succeed in bending the whole community to their will. Using computer models and behavioural studies of fish, a team of scientists, including researchers from the Max Planck Institute for the Physics of Complex Systems in Dresden, has discovered that uninformed individuals support the decision of the majority and may prevent a particularly determined ...

Traumatic experiences may make you tough
2011-12-19
Your parents were right: Hard experiences may indeed make you tough. Psychological scientists have found that, while going through many experiences like assault, hurricanes, and bereavement can be psychologically damaging, small amounts of trauma may help people develop resilience.
"Of course, everybody's heard the aphorism, 'Whatever does not kill you makes you stronger,'" says Mark D. Seery of the University at Buffalo. His paper on adversity and resilience appears in the December issue of Current Directions in Psychological Science, a journal of the Association for ...
Quantum cats are hard to see
2011-12-19
Are there parallel universes? And how will we know? This is one of many fascinations people hold about quantum physics. Researchers from the universities of Calgary and Waterloo in Canada and the University of Geneva in Switzerland have published a paper this week in Physical Review Letters explaining why we don't usually see the physical effects of quantum mechanics.
"Quantum physics works fantastically well on small scales but when it comes to larger scales, it is nearly impossible to count photons very well. We have demonstrated that this makes it hard to see these ...

Midwives use rituals to send message that women's bodies know best
2011-12-19
CORVALLIS, Ore. – In reaction to what midwives view as the overly medicalized way hospitals deliver babies, they have created birthing rituals to send the message that women's bodies know best.
The midwife experience uses these rituals to send the message that home birth is about female empowerment, strengthening relationships between family and friends, and facilitating participatory experiences that put mothers in control, with the ultimate goal of safe and healthy deliveries less focused on technological intervention.
These are some of the findings from an Oregon ...

Caterpillars mimic one another for survival
2011-12-19
In the world of insects, high risk of attack has led to the development of camouflage as a means for survival, especially in the larval stage. One caterpillar may look like a stick, while another disguises itself as bird droppings. Though crypsis may have its advantages, University of Florida researchers uncovered some of the most extensive evidence of caterpillars using another strategy previously best-known in adult butterflies: mimicry.
Insects use camouflage to protect themselves by looking like inanimate or inedible objects, while mimicry involves one species evolving ...
Does team training save lives? A new science gives it a rigorous evaluation
2011-12-19
Whether the task is flying a plane, fighting a battle, or caring for a patient, good teamwork is crucial to getting it done right. That's why team-building and training courses are big business in the U.S., and have been for decades. But lately something has changed: "There's a demand for evaluations—an emphasis on showing that team training makes a difference in safety, decision-making, communication, clinical outcomes—you name the ultimate criteria the industry has," says Eduardo Salas, an organizational psychologist at the University of Central Florida.
