In Many nonhuman Primates, the sight of red on a female sexually inflames the male of the species, on to tell inspiring flamboyant and explicit displays of arousal. Researchers say That They have for the first-time Identified analogous Rather f-Reactions to more subtle color That Among men.
In a new study, Designed to Mimic the dynamic of online dating, male undergraduates Were shown a photograph of a "moderately attractive young adult woman" Whose shirt hadd been doctored, with Photoshop, to Appear either red or green. The researchers Told the men Was That this woman in the next room and tell Presented with 24 Questions That They Might ask her; Could They select five. When the woman in the photo wearing red Was, Were the men significantly more forward Likely to ask Questions ( "Normally Where do you hang out?" "How Could a guy get your Attention at a bar?"). If She Was wearing green, the more tilted Towards Questions "Where are you from?"
In a related study, led men to believe That Were They Were about to meet a woman and Were Directed to the chair sitting Where she WOULD BE. If They Were expecting a woman in a red shirt, They positioned themselves closer to the chair than the if They Were expecting someone in blue. (Sad coda: the lady in red never showed.)

Avoiding the Wall
Some 40% of marathoners experience of hitting the fate makeup What They call "the wall." Often around the 20-mile mark, Basically the body gives out, and the runners either grimly soldier on, with a much-diminished performance, or broke the drop out.
Runners fatalistically view the wall, soft a researcher has crafted a formula to help tell Avoid It. When runners hit the wall They burn through carbohydrates Their on-board and begin dipping luck Into reserve. So the more chance of hitting the wall Can Be describedat as a function of aerobic Efficiency, pace and carbs eaten During the race.
A common Efficiency Measure of aerobic is "VO2 max," or optimal oxygen uptake, Which is Determined using special equipment and a treadmill. But the paper offers a way of Estimating it by measuring your heartbeat Given at a running pace. It Also Provides charts let you gauge That Whether, at Any Given speed, you'll hit the wall.
For example, people with roughly the maximum VO2 max Achieve That nonelite athletes through training Should Be Able to run a marathon in three hours and 10 minutes without the vicious end-fade. If they're a little below That level, They'd Need to eat 700 calories During competition.
The author Plans to Provide an online calculator, Which shouldnt make it Easier for runners to view the wall as a problem to swear Solved, Rather than as a demonic, capricious fiend.

Power Posing
Sitting in a corporate anteroom, waiting for a job interview to begin, you Might want to put your hands behind your head, lean back, and kick up your legs. Might Raise an Eyebrow onlookers, But that's a small price to pay for success.
Such a position is a kind of physically open position, known as a "power pose" That Produces an array of Benefits, Including a surge of testosterone and a Decrease in the stress hormone cortisol, according to a new study.
For the study, one group of subjects That Was Asked to Adopt open pose sitting in a laboratory for one minute, and pointed to a second power Adopt pose, standing, leaning forward, arms planted broadly on a desk. A second group of test subjects Was Assigned "weak" poses-for instance, sitting with legs close together or developer's developer's crossing arms. All make-work Were Given to tell Distract from the Purpose of the study.
In addition to getting a dip in testosterone Boost and stress, doing power poses Reported Those feeling significantly more potent and "in charge," and They Were more property to take rational Risks in gambling tasks.

Fluid Dynamics
The Wet-Dog Shake Theory
Dogs shake to get dry, and small dogs shake faster than big dogs. This much we know. But researchers at the Georgia Institute of Technology That Were not satisfied with level of folk knowledge, so They set out to elaborate a grand theory of wet-dog shaking-One That Can Be extended to cover mice and Grizzly bears as well.
The "oscillatory shaking" of dogs and other animals Follows a regular back-and-Forth pattern, Beginning at the head and spreading to the tail. (And it is very cute When filmed in slow motion, as done for the study videos attest.) The shaking must Generate enough force to break the surface tension holding the water to the animal.
The researchers plotted a curve Showing the inverse relationship between an animal's size and its speed shaking. A mouse oscillated at a rate of 27 Hertz, the while a mid-size dog moved at 5.8 Hz. They concluded that, as an animal got bigger, its shaking frequency gradually approached, soft didnt Reach, 4 Hz. At first, the researchers thought the curve Was Purely a function of animal-radius torso, soft They HAD to tweak Into Their model to take account the additional influence of fur length.
