New study shows false memories affect behavior Do you know someone who claims to remember their first day of kindergarten? Or a trip they took as a toddler? While some people may be able to recall trivial details from the past, laboratory research shows that the human memory can be remarkably fragile and even inventive.

Switching it up: How memory deals with a change in plans Adjusting our behavior to such changing circumstances enables us to achieve our goals. But how, exactly, do our brains switch so elegantly and quickly from one well-entrenched plan to a newer one in reaction to a sudden change in circumstances?

Resistant prions: Living in the soil A flock of sheep at pasture – a seemingly idyllic scene. But appearances can be deceptive: If the animals are suffering from scrapie, entire flocks may perish. Scrapie is an infectious disease in which prions destroy the animal's brain, much like BSE.

Genes may make some people more prone to anxiety Inborn differences may help explain why trauma gives some people bad memories and others the nightmare of post-traumatic stress. Scientists in Germany and the United States have reported evidence linking genes to anxious behavior. The findings appear in the August issue of Behavioral Neuroscience, published by the American Psychological Association.

Water is 'designer fluid' that helps proteins change shape, scientists say According to new research, old ideas about water behavior are all wet. Ubiquitous on Earth, water also has been found in comets, on Mars and in molecular clouds in interstellar space. Now, scientists say this common fluid is not as well understood as we thought.

The school bully -- does it run in the family? A shove, a taunt or name-calling on the playground or in the hall, away from the eyesight, earshot and authority of the teacher – childhood bullying can involve physical contact, spreading rumors and other negative behaviors committed over and over again to intimidate, humiliate and isolate the receiver of the behavior.

Climate change and species distributions Scientists have long pointed to physical changes in the Earth and its atmosphere, such as melting polar ice caps, sea level rise and violent storms, as indicators of global climate change. But changes in climate can wreak havoc in more subtle ways, such as the loss of habitat for plant and animal species.

Aging impairs the 'replay' of memories during sleep Aging impairs the consolidation of memories during sleep, a process important in converting new memories into long-term ones, according to new animal research in the July 30 issue of The Journal of Neuroscience. The findings shed light on normal memory mechanisms and how they are disrupted by aging.

Scientists discover new class of glassy material Scientists at U.S. Department of Energy's Argonne National Laboratory are dealing with an entirely new type of frustration, but it's not stressing them out. Dynamic frustration has been found to be the cause of glassy behavior in materials that previously had none of the features of a normal glass.

Newly discovered proteins in seminal fluid may affect odds of producing offspring Seminal fluid contains protein factors that, when transferred from a male to a female at mating, affect reproductive success. This is true of many different animals, from crickets to primates. In fruit flies, for instance, seminal fluid proteins influence the competitive ability of a male's sperm, and alter the female's post-mating behavior by dampening her interest in other males and cueing her t

A bee's future as queen or worker may rest with parasitic fly Strange things are happening in the lowland tropical forests of Panama and Costa Rica. A tiny parasitic fly is affecting the social behavior of a nocturnal bee, helping to determine which individuals become queens and which become workers.

Reflecting on values promotes love, acceptance No one enjoys being told that their behavior is harmful to themselves or others. In fact, most people respond defensively when confronted with evidence that their behavior is irrational, irresponsible, or unhealthy. Fortunately, research has shown that just a few minutes of writing about an important value can reduce defensiveness.

New study sheds light on how intracellular pathogens trigger the immune system Disease-causing microbes like the food-borne bacterium Listeria monocytogenes specialize in invading and replicating inside their animal hosts' own cells, making them particularly tricky to defeat. Now, a new study has identified a molecular alarm system in which the intracellular pathogen sends out signals that kick the immune response into gear.

Now located on an isolated island off New York, the lab could be moved to North Carolina, Mississippi, Georgia, Texas, or Kansas. Local residents, farmers and ranchers are worried, while local officials anticipate the money and prestige the lab might bring.

Could Climate Change Impact Costa Rica? New Study Says Yes Climate change could have a major impact on the environment of Costa Rica, upsetting delicate mountain cloud forests, and causing a decrease in plant and animal species in a region famous for its biodiversity. Regional climate models predict that the area will become warmer and drier as climate change accelerates.

Money makes the heart grow less fond... but more hardworking Money is a necessity: it provides us with material objects that are important for survival and for entertainment, and it is often used as a reward. But recent studies have shown that money is not only a device for gaining wealth, but a factor in personal performance, interpersonal relations and helping behavior, as well.

Brain chemical shown to induce both desire and dread The chemical dopamine induces both desire and dread, according to new animal research in the July 9 issue of The Journal of Neuroscience. Although dopamine is well known to motivate animals and people to seek positive rewards, the study indicates that it also can promote negative feelings like fear.

Synthetic molecules emulate enzyme behavior for the first time When chemists want to produce a lot of a substance -- such as a newly designed drug -- they often turn to catalysts, molecules that speed chemical reactions. Many jobs require highly specialized catalysts, and finding one in just the right shape to connect with certain molecules can be difficult.
