Published Poor work performance among Japanese employees strongly associated with insufficient sleep (via sciencedaily.com) Original source
This study examined the association between work performance and lifestyle habits among Japanese employees. The results revealed that insufficient sleep was the predominant factor affecting work performance in men and women, followed by lack of regular exercise and eating late-evening meals. Furthermore, the study indicated that men were more likely to exhibit lifestyle habits that impacted work performance than women.
Published Feeding dogs raw meat increases the risk of antibiotic-resistant E. coli (via sciencedaily.com) Original source
Feeding dogs raw (uncooked) meat increases their risk of excreting E. coli that cannot be killed by a widely used antibiotic -- ciprofloxacin -- researchers have found from a study of 600 healthy pet dogs.
Published Following a Mediterranean diet reduces the risk of cognitive decline in older people (via sciencedaily.com) Original source
Old people who follow a Mediterranean diet are at a lower risk of cognitive decline, according to a new study. The study provides new evidence for a better understanding of the biological mechanisms related to the impact of the diet on cognitive health in the aging population.
Published People with obesity burn less energy during day (via sciencedaily.com) Original source
A study found people who have a healthy weight use more energy during the day, when most people are active and eat, while those who have obesity spend more energy during the night, when most people sleep. Researchers also found that, during the day, those with obesity have higher levels of the hormone insulin -- a sign that the body is working harder to use glucose, an energy-packed sugar.
Published Exposure to air pollution in utero may affect reproductive system development (via sciencedaily.com) Original source
From invisible wafts of diesel exhaust to sun-choking plumes of orange smoke, air pollution is known to damage respiratory well-being. Now, research suggests another reason to hold our breath: Polluted air also may hurt reproductive health. In a study of air pollution data in relation to markers of reproductive development in infancy, Rutgers researchers found certain pollutants may negatively alter anogenital distance, a measure of prenatal exposure to hormones.
Published New study finds association between insecticide exposure and lower sperm concentration in adult men (via sciencedaily.com) Original source
Researchers have found in a new systematic review that there is a strong association between insecticide exposure and lower sperm concentration in adult men globally.
Published Peer educators play key role in new recipe development and testing (via sciencedaily.com) Original source
Cooking and recipe demonstrations encourage healthy eating and adoption of unfamiliar foods by class participants.
Published Allergic responses to common foods could significantly increase risk of heart disease, cardiovascular death (via sciencedaily.com) Original source
Allergic responses to common foods such as dairy and peanuts can increase the risk for heart disease and cardiovascular death as much or more than smoking, new research suggests. And these dangerous allergic responses can strike both people with food allergies and those with no obvious allergy symptoms.
Published Practicing mindfulness can help people make heart-healthy eating choices (via sciencedaily.com) Original source
A study found that participants in a mindfulness-based blood pressure reduction program improved health behaviors that lower blood pressure. When people who had elevated blood pressure participated in an eight-week mindfulness-based blood pressure reduction program, they significantly improved their scores on measures of self-awareness and adherence to a heart-healthy diet compared to a control group.
Published Mobile phone use may affect semen quality, study shows (via sciencedaily.com) Original source
Does electromagnetic radiation emitted by mobile phones affect semen quality? While various environmental and lifestyle factors have been proposed to explain the decline in semen quality observed over the last fifty years, the role of mobile phones has yet to be demonstrated. A team has now published a major cross-sectional study on the subject. It shows that frequent use of mobile phones is associated with a lower sperm concentration and total sperm count.
Published Sperm adjust their swimming style to adapt to fluctuating fluid conditions (via sciencedaily.com) Original source
Sperm can modulate their energetics by regulating their flagellar waveform -- how the sperm oscillate their tails -- in order to adapt to varying fluid environments, potentially optimizing their motility and navigation within the reproductive tract, according to new research.
Published COVID vaccination in female, male partners does not increase risk of miscarriage, study finds (via sciencedaily.com) Original source
A new study provides deeper insight into the safety of COVID-19 vaccines for people planning to become pregnant. The study found no increased risk of early or late miscarriage as a result of male or female partners getting a COVID-19 vaccine prior to conceiving.
Published Possible cause of male infertility (via sciencedaily.com) Original source
Mature spermatozoa are characterized by an head, midpiece and a long tail for locomotion. Now, researchers have found that a loss of the structural protein ACTL7B blocks spermatogenesis in male mice. The cells can no longer develop their characteristic shape and remain in a rather round form. The animals are infertile.
Published Membrane transporter ensures mobility of sperm cells (via sciencedaily.com) Original source
Special proteins -- known as membrane transporters -- are key to the mobility of sperm cells. A research team has, with the aid of cryo-electron microscopy, succeeded in decoding the structure of such a transporter and its mechanism. These findings will enable a better understanding of the molecular foundations of reproductive capacity and could, in the long term, contribute to developing new approaches to treating fertility disorders and new methods of specific contraception.
Published Study shows simple diet swaps can cut carbon emissions and improve your health (via sciencedaily.com) Original source
Making one small diet change -- chicken instead of beef, plant milk instead of cow's milk -- could significantly curb carbon emissions and increase the healthfulness of your diet, according to a new study.
Published Study suggests that having common ancestors can jeopardize fertility for generations (via sciencedaily.com) Original source
New research provides rare direct evidence showing that increased homozygosity -- meaning two identical alleles in a genome -- leads to negative effects on fertility in a human population.
Published Bacteria can enhance host insect's fertility with implications for disease control (via sciencedaily.com) Original source
New research reveals how the bacteria strain Wolbachia pipientis enhances the fertility of the insects it infects, an insight that could help scientists increase the populations of mosquitoes that do not carry human disease.
Published Why do some men not produce sperm? (via sciencedaily.com) Original source
Millions of couples worldwide experience infertility with half of the cases originating in men. For 10 percent of infertile males, little or no sperm are produced. Now, new research is shedding light on what may be going wrong in the process of sperm formation, leading to potential theories on possible treatments.
Published Study finds men's antidepressant use did not negatively impact IVF success (via sciencedaily.com) Original source
In vitro fertilization (IVF) is a time-intensive and often stress-inducing fertility procedure. Yet how does that stress impact its success? Investigators have now assessed the effects of anxiety and depression in men on fertility and IVF outcomes.
Published Researchers uncover mechanism that links NAD+ to fertility problems (via sciencedaily.com) Original source
A woman's fertility normally decreases by her late 30s with reproductive function eventually ceasing at menopause. It is known that a small molecule called nicotinamide adenine dinucleotide (NAD+) plays a critical role in this decline, and scientists have revealed how this happens and have identified potential new approaches to enhance reproductive longevity.
