Cat Bird in the Garden

WhitesCreek Journal - 44 min 29 sec ago
Every year brings surprises in Whites Creek Gorge. It is most likely that we just notice things anew that have been here all along, but bird behavior is a volatile thing, adjusts for weather conditions from year to year. I saw my first black throated blue warbler yesterday, comfirmed by a friend who also saw her first in her yard a few miles away. I had no chance for a picture of the black

A new 'APEX' in plant studies aboard the International Space Station

Science News Daily - April 22, 2014 - 11:57am
Growing knowledge in a given field takes time, attention, and ... water? It does when you're talking about plant studies aboard the International Space Station (ISS). All of these things and some scientific know-how come into play as astronauts find out just how green their thumbs are while assisting researchers on the ground.

For an immune cell, microgravity mimics aging

Science News Daily - April 22, 2014 - 11:54am
Telling someone to "act your age" is another way of asking him or her to behave better. Age, however, does not always bring improvements. Certain cells of the immune system tend to misbehave with age, leaving the elderly more vulnerable to illness. Because these cells are known to misbehave similarly during spaceflight, researchers are studying the effects of microgravity on immune cells to better understand how our immune systems change as we age.

Neurotics don't just avoid action: They dislike it, study finds

Science News Daily - April 22, 2014 - 11:12am
Neurotics don't just avoid taking action. By their very nature they dislike it. A study of nearly 4,000 college students in 19 countries has uncovered new details about why neurotic people may avoid making decisions and moving forward with life. Turns out that when they are asked if action is positive, favorable, good, they just don't like it as much as non-neurotics. Framing communication messages that get around this roadblock is a key to success communication with neurotic folks.

Applying math to biology: Software identifies disease-causing mutations in undiagnosed illnesses

Science News Daily - April 22, 2014 - 11:12am
A computational tool has successfully identified diseases with unknown gene mutations in three separate cases. Sequencing the genomes of individuals or small families often produces false predictions of mutations that cause diseases. But this study shows that a new unique approach allows it to identify disease-causing genes more precisely than other computational tools.

Fat metabolism in animals altered to prevent most common type of heart disease

Science News Daily - April 22, 2014 - 11:10am
Working with mice and rabbits, scientists have found a way to block abnormal cholesterol production, transport and breakdown, successfully preventing the development of atherosclerosis, the main cause of heart attacks and strokes and the number-one cause of death among humans. The condition develops when fat builds inside blood vessels over time and renders them stiff, narrowed and hardened, greatly reducing their ability to feed oxygen-rich blood to the heart muscle and the brain.

Online retailers have clear advantage by not collecting sales tax

Science News Daily - April 22, 2014 - 11:09am
Two independent studies use two very different approaches to reach the same conclusion: some online retailers really do have an advantage over traditional brick-and-mortar stores. The studies find evidence from investors, analysts and consumers themselves that suggest online stores have a competitive edge when they don't have to collect sales tax from shoppers.

Wildlife response to climate change is likely underestimated, experts warn

Science News Daily - April 22, 2014 - 10:34am
Analyzing thousands of breeding bird surveys sent in by citizen scientists over 35 years, wildlife researchers report that most of the 40 songbird species they studied shifted either northward or toward higher elevation in response to climate change, but did not necessarily do both. This means that most previous studies of potential climate change impacts on wildlife that looked only at one factor or the other have likely underestimated effects.

Male health linked to testosterone exposure in womb, study finds

Science News Daily - April 22, 2014 - 10:34am
Men's susceptibility to serious health conditions may be influenced by low exposure to testosterone in the womb, new research suggests. Understanding why some men have less of the hormone than others is important because testosterone is crucial for life-long health. Low levels of the hormone have been linked to obesity, diabetes and heart disease.

Brain size matters when it comes to animal self-control

Science News Daily - April 22, 2014 - 10:34am
Chimpanzees may throw tantrums like toddlers, but their total brain size suggests they have more self-control than, say, a gerbil or fox squirrel, according to a new study of 36 species of mammals and birds ranging from orangutans to zebra finches.

Life stressors trigger neurological disorders, researchers find

Science News Daily - April 22, 2014 - 10:34am
When mothers are exposed to trauma, illness, alcohol or other drug abuse, these stressors may activate a single molecular trigger in brain cells that can go awry and activate conditions such as schizophrenia, post-traumatic stress disorder and some forms of autism. Until now, it has been unclear how much these stressors have impacted the cells of a developing brain. Past studies have shown that when an expectant mother exposes herself to alcohol or drug abuse or she experiences some trauma or illness, her baby may later develop a psychiatric disorder later in life. But the new findings identify a molecular mechanism in the prenatal brain that may help explain how cells go awry when exposed to certain environmental conditions.

Speed-reading apps may impair reading comprehension by limiting ability to backtrack

Science News Daily - April 22, 2014 - 10:34am
To address the fact that many of us are on the go and pressed for time, app developers have devised speed-reading software that eliminates the time we supposedly waste by moving our eyes as we read. But don't throw away your books, papers, and e-readers just yet -- research suggests that the eye movements we make during reading actually play a critical role in our ability to understand what we've just read.

People pay more attention to upper half of field of vision, study shows

Science News Daily - April 22, 2014 - 10:33am
People pay more attention to the upper half of their field of vision, a study shows, a finding that could have ramifications for traffic signs to software interface design. "It doesn't mean people don't pay attention to the lower field of vision, but they were demonstrably better at paying attention to the upper field," the lead researcher says.
