Published What can bulls tell us about men? (via sciencedaily.com) Original source
Researchers have found genes in the reproductive organs of bulls that influence fertility. The findings can be transferred to humans, as these genes are also present in men.
Published Reported marital harmony -- or conflict -- accounts for nearly ten percent of the variation in mental health self-assessments in a broad study of Australian adults (via sciencedaily.com) Original source
Australian adults who report a good relationship that meets their original expectations tend to score higher in mental health, while adults who report loving their spouse but wished they had never entered the relationship and note relationship problems tend to score significantly lower in mental health, according to a survey of almost 7000 Australian adults.
Published Genetic cause of low birth weight among children conceived after fertility treatment (via sciencedaily.com) Original source
A medical researcher has identified a genetic cause for the increased risk of low birth weight in babies born following assisted reproductive technologies such as IVF.
Published Low voice pitch increases standing among strangers (via sciencedaily.com) Original source
If you're looking for a long-term relationship or to boost your social status, lower your pitch, according to researchers studying the effects of voice pitch on social perceptions. They found that lower voice pitch makes women and men sound more attractive to potential long-term partners, and lower voice pitch in males makes the individual sound more formidable and prestigious among other men.
Published 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.
Published How ovarian tissue freezing could prevent menopause -- possibly forever (via sciencedaily.com) Original source
A new paradigm around the biological processes of menopause is capturing the attention of scientists. The primary question: can menopause be delayed in healthy women, allowing them to extend their child-bearing years -- and perhaps even forestall some of the health risks and uncomfortable symptoms linked to plummeting estrogen levels?
Published Looking for love? Try finding purpose as well (via sciencedaily.com) Original source
The world of online dating can be overwhelming with the dizzying array of options for attracting a partner but new research shows that those looking for love may have more success if they also seek a sense of purpose in life.
Published Gene expression atlas captures where ovulation can go awry (via sciencedaily.com) Original source
An interdisciplinary collaboration used a cutting-edge form of RNA tagging to map the gene expression that occurs during follicle maturation and ovulation in mice.
Published Couples: Caring for oneself can lead to happier relationships -- on both sides (via sciencedaily.com) Original source
Being more forgiving of your own shortcomings in a romantic relationship can lead to happier couples. A total of 209 heterosexual couples were surveyed. The results show that men in particular benefit if their partner is self-compassionate. The results provide important information for couples' therapies, as self-compassion can be trained.
Published 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.
Published Semen microbiome health may impact male fertility (via sciencedaily.com) Original source
A new study finds that a small group of microorganisms may be influencing sperm motility.
Published Surprise discovery: For most animals, sperm quality does not reduce with age (via sciencedaily.com) Original source
In humans, male fertility and sperm fitness decline with age, but scientists have made the surprising discovery that this pattern is not consistent in other animals. The team assessed the results of 379 studies which covered a wide range of animals, including mammals, insects, birds, and fish.
Published Online versus reality: Social media influences perceptions (via sciencedaily.com) Original source
People may form inaccurate impressions about us from our social media posts, finds new research that is the first to examine perceptions of our personalities based on online posts.
Published 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.
Published 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.
Published 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.
Published Love scrambles the brain and scientists can now tell us why (via sciencedaily.com) Original source
Love is blind, the saying goes, and thanks to a new study we are now a step closer to understanding why. Researchers have measured how a part of the brain is responsible for putting our loved one on a pedestal in that first flush of romance.
Published 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.
Published 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.
Published 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.
