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

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.

Cleaned surfaces may be germ-free, but they're not bare

Since the outbreak of COVID-19, surfaces in public spaces are cleaned more often. While disinfectant solutions eliminate germs, they don't leave behind a truly bare surface. They deposit a thin film that doesn't get wiped up, even after giving the surface a good polish. In a new study, researchers show that residues left by commercial cleaning products contain a wider range of compounds that could impact indoor air quality than... Read more ›

Researchers uncover mechanisms behind enigmatic shapes of nuclei

White blood cells known as neutrophils feature a nucleus that is structured strikingly different than most nuclei. These unique shapes permit neutrophils to travel all over the body to combat invading pathogens. Scientists have now deciphered the shapeshifting puzzle of the neutrophil nucleus. Read more ›

Red nets signal 'stop' to insect pests, reduce need for insecticides

Red nets are better at keeping away a common agricultural insect pest than typical black or white nets, according to a new study. Researchers experimented with the effect of red, white, black and combination-colored nets on deterring onion thrips from eating Kujo leeks, also called Welsh onions. In both lab and field tests, red nets were significantly better at deterring the insect than other colors. Also, in field tests, onion... Read more ›

New understanding of avian eggshell attachment -- implications for medical procedures and egg industry

Athletes often suffer injuries to ligaments in their knees, particularly to the anterior cruciate ligament or ACL. While surgery to replace these torn ligaments is becoming increasingly common around the world it often needs to be repeated. That's because it has proved challenging to anchor fibrous, soft and wet ligament grafting material into hard bone. Now, researchers have new information from the eggshell membrane in chicken eggs that could help... Read more ›

The role of jellies as a food source in the Arctic winter

The Arctic is changing rapidly due to climate change. It is not only affected by increasing surface temperatures, but also by warm water from the Atlantic, which is flowing in more and more -- changing the structures and functions of the ecosystem as it also leads to species from warmer regions, such as sea jellies (also known as jellyfish) arriving in the Arctic. Using DNA metabarcoding, researchers have now been... Read more ›

Pesticides to help protect seeds can adversely affect earthworms' health

While pesticides protect crops from hungry animals, pesky insects, or even microbial infections, they also impact other vital organisms, including bees and earthworms. And today, research reveals that worms are affected by the relatively small amounts of chemicals that can leach out of pesticide-treated seeds. Exposure to nonlethal amounts of these insecticides and fungicides resulted in poor weight gain and mitochondrial DNA (mtDNA) damage in the worms. Read more ›

Did Eurasia's dominant East-West axis 'turn the fortunes of history'?

Jared Diamond proposed that Eurasia's unique geographic axis of orientation fueled a rapid spread of critical innovations among its societies, leading to a cultural and military dominance over other regions. A team of ecologists and cultural evolutionists from the USA, Germany and New Zealand harnessed extensive cultural, environmental and linguistic databases to test these claims. They found that environmental barriers have influenced cultural spread but do not consistently favour Eurasia. Read more ›

COVID-19 vaccination and boosting during pregnancy protects infants for six months, study finds

Women who receive an mRNA-based COVID-19 vaccination or booster during pregnancy can provide their infants with strong protection against symptomatic COVID-19 infection for at least six months after birth, according to a new study. These findings reinforce the importance of receiving both a COVID-19 vaccine and booster during pregnancy to ensure that infants are born with robust protection that lasts until they are old enough to be vaccinated.

By growing animal cells in rice grains, scientists dish up hybrid food

From lab-grown chicken to cricket-derived protein, these innovative alternatives offer hope for a planet struggling with the environmental and ethical impacts of industrial agriculture. Now, scientists add a new recipe to the list -- cultured beef rice -- by growing animal muscle and fat cells inside rice grains. The method results in a nutritious and flavorful hybrid food that, once commercialized, could offer a more affordable protein alternative with a... Read more ›
