Bursts of waves drive immune system 'soldiers' toward invaders

...of the cell, the scientists report. "One of the things that I find fascinating about these waves is how relatively simple patterns of protein interaction can generate very complex behaviors," says Weiner. "Evolution has found the same solution to generating waves again and again even with completely diff...

Swarming starlings help probe plasma, crowds and stock market

...d by the small number of satellites observing such things and plasmas in nuclear fusion reactions are obviously not easily accessible. The University of Warwick researchers were particularly interested in how complex systems such as plasma, crowds of people, or flocks of birds suddenly move from a disor...

Disabling a sensory organ prompts female mice to act like male mice

...r, according to Dulac. "Now we can really approach things from a mechanistic point of view," she said. "We can trace signaling events in the brain and see how brain areas controlling sex-specific behaviors are connected to each other."...

MIT team building robotic fin for submarines

...can hover and turn and store energy and do all the things a fish does, they'll be much better than the remotely operated vehicles we have now, said James Tangorra, an MIT postdoctoral associate working on the project. The researchers chose to copy the bluegill sunfish because of its distinctive swimming m...

The inside dope

Often, things can be improved by a little 'contamination.' Steel, for example is iron with a bit of carbon mixed in. To produce materials for modern electronics, small amounts of impurities are introduced into silicon a process called doping. It is these impuriti...

Presence of wolves allows aspen recovery in Yellowstone

...ong time to see this, but now were optimistic that things may be on the right track. The study found significant numbers of aspen, especially in streamside riparian zones, that have grown from tiny shoots in the past decade to heights of more than seven feet a key point in their long-term survival, placi...

Females more prone to brain damage from alcohol abuse

...ed) genes are involved in the pathway for cleaning things up," Wiren said. The genes respond with "removal of damaged proteins. The females have all this apoptosis (cell death) going on, and the males instead may have repair going on." Such brain damage may underlie debilitating cognitive dysfunction and ...

Adult survivors of childhood leukemia exercise less, worsening high risk for obesity and illness

Killing only a few animals won't do any harm -- or will it?

...e class is the target of mortality that unexpected things may happen. Van Kooten and co-workers predict for example that in harvested cannibalistic fish populations, individuals may reach giant sizes, more than double the size of those in unharvested population. Indeed, such giant cannibals seem to occur f...

We have to ask ourselves how those changes will affect our way of life. Another speaker, Dr John Hurd, director of conservation for the Global Heritage Fund, wil...

Research study describes the role part of the brain plays in memory

...strument. Declarative memory allows us to remember things such as specific moments of our lives, names of people, what we ate for lunch, the capitals of the world, etc. The malfunctioning of this type of memory is one of the most common symptoms found in those suffering from Alzheimer's disease. A useful ...
