Latest Science News Brain “Relay” Also Key to Holding Thoughts in Mind • Press Release Long overlooked as a mere “relay,” an egg-like structure in the middle of the brain also turns out to play a pivotal role in tuning-up thinking circuity. A trio of studies in mice are revealing that the thalamus sustains the ability to distinguish categories and hold thoughts in mind. It might even become a target for interventions for psychiatric disorders marked by working memory problems, such as schizophrenia.

The Chameleon Effect and Chartrand & Bargh Experiments.
Also called unintentional mirroring, the chameleon effect usually applies to people who are getting along so well, each tend to mimic each other's body posture, hand gestures, speaking accents, among others. This was confirmed by the Chartrand and Bargh experiments. The perfect description of the chameleon effect is the cliché saying: "Imitation is the best form of flattery. " In interpersonal relations, often times mimicking another's body language can increase our likeability. According to Chartrand and Bargh, the chameleon effect is the natural tendency to imitate another person's speech inflections and physical expressions.
Statement of the Problem In 1999, two professors of Psychology at New York University conducted experiments that will study the phenomenon of the chameleon effect. Methodology In Chartrand and Bargh's first experiment, 78 individuals were asked to have a one-on-one talk with one of the experimenters.

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.

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.
"A travelling wave can be triggered by any penguin in a huddle," says co-author Dr Daniel Zitterbart from the Alfred Wegener Institute in Germany. The findings follow more than two years of observing colonies of emperor penguins in Antarctica. Earlier research has shown that penguins move "in a co-ordinated way, like a Mexican wave in a stadium," according to Zitterbart. "So if they want to move, they don't need to break up - they can just move together. " This means penguins can keep moving while still huddled together to keep warm. Traffic jam rules. Giant Honeybees Use Shimmering 'Mexican Waves' To Repel Predatory Wasps -- ScienceDaily. 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. 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.
Zucchini offers useful amounts of some vitamins and minerals, but cooking reduces its nutritional value. Growers cut zucchini only days after the fruits pollinate. Tender zucchini squashes need no cooking. One raw baby zucchini weighing 16 g contains only 14 calories and yields about 1 cup of sliced or grated raw zucchini. Over 90 percent of a zucchini squash consists of water. Choose only the freshest zucchini to serve raw. Flavorings contribute both calories and nutrition to cooked zucchini dishes. Co.Labs ⚙ code + community. Brain, Brain Information. 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 neurons transmit and gather electrochemical signals that are communicated via a network of millions of nerve fibers called dendrites and axons. The cerebrum has two halves, or hemispheres. Movement and Balance. Catalyst: Staying Up Late - ABC TV Science. 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.
One famous analogy to explain the expanding universe is imagining the universe like a loaf of raisin bread dough. Who Figured This Out? Science Topics. Not Exactly Rocket Science. Science News – Science Articles and Current Events | LiveScience.
