Brain Information, Facts
Making sense of the brain's mind-boggling complexity isn't easy. What we do know is that it's the organ that makes us human, giving people the capacity for art, language, moral judgments, and rational thought. It's also responsible for each individual's personality, memories, movements, and how we sense the world. All this comes from a jellylike mass of fat and protein weighing about 3 pounds (1.4 kilograms). It is, nevertheless, one of the body's biggest organs, consisting of some 100 billion nerve cells that not only put together thoughts and highly coordinated physical actions but regulate our unconscious body processes, such as digestion and breathing. The brain's nerve cells are known as neurons, which make up the organ's so-called "gray matter." The cerebrum is the largest part of the brain, accounting for 85 percent of the organ's weight. The cerebrum has two halves, or hemispheres. Movement and Balance The diencephalon is located in the core of the brain.

What does it mean when they say the universe is expanding?(Everyday Mysteries: Fun Science Facts from the Library of Congress) The galaxies outside of our own are moving away from us, and the ones that are farthest away are moving the fastest. This means that no matter what galaxy you happen to be in, all the other galaxies are moving away from you. However, the galaxies are not moving through space, they are moving in space, because space is also moving. In other words, the universe has no center; everything is moving away from everything else. If you imagine a grid of space with a galaxy every million light years or so, after enough time passes this grid will stretch out so that the galaxies are spread to every two million light years, and so on, possibly into infinity. The universe encompasses everything in existence, from the smallest atom to the largest galaxy; since forming some 13.7 billion years ago in the Big Bang, it has been expanding and may be infinite in its scope.

Nutritional Facts for Raw Zucchini Vs. Cooked Zucchini Because you harvest zucchini when immature, this summer squash contains fewer nutrients than mature winter squashes that develop large stores of starch and sugar. As with cucumbers, most of the weight of a fresh zucchini comes from water. Zucchini provides good flavor and only a few calories, whether raw or cooked.

Chris Nickels for NPR Giant Honeybees Use Shimmering 'Mexican Waves' To Repel Predatory Wasps The phenomenon of "shimmering" in giant honeybees, in which hundreds—or even thousands—of individual honeybees flip their abdomens upwards within a split-second to produce a Mexican Wave-like pattern across the bee nest, has received much interest but both its precise mode of action and its purpose have long remained a mystery. In a new study published in the journal PLoS ONE this week, researchers at the University of Graz, Austria, and the Royal Botanic Gardens Kew, UK, report the finding that shimmering—a remarkable capacity of rapid communication in giant honeybees—acts as a defensive mechanism, which repels predatory hornets, forcing them to hunt free-flying bees, further afield, rather than foraging bees directly from the honeybee nest. South-East Asian giant honeybees (Apis dorsata) occur in single-comb nests in the open, preferring traditional nest sites with aggregations of hundreds of colonies on trees, rocks or human buildings, which they may revisit over years.

Brain in the News Page: 1 of 4 To Keep Your Smarts, Exercise More than Just Your Brain June, 2007 by Guy McKhann, M.D. Controlling RNA in living cells MIT researchers have devised a new set of proteins that can be customized to bind arbitrary RNA sequences, making it possible to image RNA inside living cells, monitor what a particular RNA strand is doing, and even control RNA activity. The new strategy is based on human RNA-binding proteins that normally help guide embryonic development. The research team adapted the proteins so that they can be easily targeted to desired RNA sequences. “You could use these proteins to do measurements of RNA generation, for example, or of the translation of RNA to proteins,” says Edward Boyden, an associate professor of biological engineering and brain and cognitive sciences at the MIT Media Lab. “This could have broad utility throughout biology and bioengineering.” Unlike previous efforts to control RNA with proteins, the new MIT system consists of modular components, which the researchers believe will make it easier to perform a wide variety of RNA manipulations.

Penguin Mexican waves follow traffic rules › News in Science (ABC Science) News in Science Tuesday, 17 December 2013 Katie SilverABC Penguin shuffle The co-ordinated way Emperor penguins move in a huddle follows the same stop-and-go movements of cars navigating their way through traffic, researchers have found. One small move by an individual penguin affects its neighbour and creates a wave of movement that ripples through the huddle, say the researchers publishing today in the New Journal of Physics.

Even Yeast Mothers Sacrifice All for Their Babies A mother’s willingness to sacrifice her own health and safety for the sake of her children is a common narrative across cultures — and by no means unique to humans alone. Female polar bears starve, dolphin mothers stop sleeping and some spider moms give themselves as lunch for their crawly babies’ first meal. Now an unexpected discovery at the University of California, San Francisco (UCSF) shows that even yeast “mothers” do it, giving all to their offspring — even at the cost of their own lives. As described this week in the journal Science, the UCSF scientists found that the yeast Saccharomyces cerevisiae ensures the health of its budding offspring by pushing essential internal structures known as mitochondria into them. Mitochondria are the mini powerhouses of living cells, supplying the chemical energy all yeast and higher life forms need to survive.
