How a city is organized can create less-biased citizens      (via sciencedaily.com)     Original source 

A new study presents data and a mathematical model to explain why there is more unconscious, or implicit, racial bias in some cities than others. The study, which brings together the math of cities with the psychology of how individuals develop unconscious racial biases, suggests that a city's level of implicit bias depends on how populous, diverse, and segregated that city is.

How does materialism in social media trigger stress and unhappiness?      (via sciencedaily.com)     Original source 

Clothes, cars, travel, followers: People with a materialistic mindset always want more and, above all, more than others. Social media provides them with ideal opportunities to compare themselves with others, which makes them susceptible to passive and addictive user behavior. This stresses them out and, ultimately, leads to low life satisfaction. This downward spiral, which turns materialists into less happy people, was identified in an online survey of over 1,200 participants.

Aging mouse sperm affects MicroRNA, increasing the risk of neurodevelopmental disorders      (via sciencedaily.com)     Original source 

Much is known about the added complication to pregnancy when it comes to the age of the mother, but recent studies show that the age of the father can also heighten the risk of neurodevelopmental disorders. A team of researchers has explored the impacts of paternal aging on microRNAs, the molecules that play a crucial role in regulating gene expression.

Science confirms it: Love leaves a mark on the brain      (via sciencedaily.com)     Original source 

The brain produces more of the pleasure-inducing hormone dopamine when we're longing for or hanging out with our partner, new research suggests. But when we break up, their unique 'chemical imprint' fades away. The study centers around prairie voles, which have the distinction of being among the 3 percent to 5 percent of mammals that form monogamous pair bonds.

Understanding the neuroendocrine basis for social anxiety-like behavior in male mice      (via sciencedaily.com)     Original source 

Researchers have discovered that estrogen receptor (ER), expressed in the lateral septum of the limbic system, plays a crucial role in suppressing anxiety-like behavior exhibited by male mice in social situations. They also discovered that the distribution and expression region of ER differs from that of ER.

Infertility: Sperm need a breakthrough for fertilization      (via sciencedaily.com)     Original source 

A new study identifies the defective function of CatSper, an ion channel controlling calcium levels in sperm, as a common cause of seemingly unexplained male infertility. CatSper-deficient human sperm fail to fertilize the egg, because they cannot penetrate its protective vestments. Thus far, this sperm channelopathy has remained undetectable. Scientists have unravelled CatSper's role in infertility using a novel laboratory test that identifies affected men.

Preconception stress may affect health of women undergoing fertility treatment      (via sciencedaily.com)     Original source 

Stress during pregnancy is known to influence health outcomes, but a new study suggests that stress levels before pregnancy are also important to evaluate. Investigators analyzed the link between self-reported stress immediately before conception among women seeking fertility care and blood glucose levels, a marker of heart health. The team found that maternal stress during preconception was associated with higher blood glucose levels, especially among women using intrauterine insemination to conceive and women of higher socioeconomic status.

Nematode proteins shed light on infertility      (via sciencedaily.com)     Original source 

Biologists developed a method for illuminating the intricate interactions of the synaptonemal complex in the nematode C. elegans. The authors identified a trio of protein segments that guide chromosomal interactions, and pinpointed the location where they interact with each other. Their novel method uses a technique known as genetic suppressor screening, which can serve as a blueprint for research on large cellular assemblies that resist traditional structural analysis.
