Scientists have uncovered why a food-ingredient-based pesticide made from safflower and cottonseed oils is effective against two-spotted spider mites that attack over a thousand species of plants while sparing the mites' natural predators.
An international team of scientists has uncovered how a bio-pesticide works against spider mites while sparing their natural predators.
The findings, published in the journal Engineering in Life Sciences on October 7, 2020, could present farmers and gardeners with an eco-friendly alternative to synthetic pesticides.
CLEVELAND, Ohio (January 5, 2021)--Sexual dysfunction often accompanies the menopause transition. Yet, not all women experience it the same. A new study identified the determinants that affect a woman's risk of sexual dysfunction and sought to determine the effectiveness of hormone therapy in decreasing that risk and modifying sexual behavior. Study results are published online in Menopause, the journal of The North American Menopause Society (NAMS).
CLEVELAND, Ohio (January 5, 2021)--Fiber is a commonly recommended part of a healthy diet. That's because it's good for your health in so many ways--from weight management to reducing the risk of diabetes, heart disease, and some types of cancer. A new study also finds that it might be linked with a reduced risk of depression, especially in premenopausal women. Study results are published online in Menopause, the journal of The North American Menopause Society (NAMS).
Microscopy -- Nanoscale commuting
Oak Ridge National Laboratory's Center for Nanophase Materials Sciences, or CNMS, contributed to a groundbreaking experiment published in Science that tracks the real-time transport of individual molecules.
Microorganisms are the most abundant and diverse form of life on Earth. However, the vast majority of them remain unknown. Indeed, only a small fraction of the microorganisms of our planet can be cultured under traditional conditions, leaving a world of unculturable organisms out of our scope. This is especially true for bacteria thriving under extreme conditions as the harsh conditions are hardly reproducible in a lab. While some microbial studies have been performed in the Sahara, the Atacama, and the Gibson desert, European arid lands remain poorly studied.
The asteroid impact 66 million years ago that ushered in a mass extinction and ended the dinosaurs also killed off many of the plants that they relied on for food. Fossil leaf assemblages from Patagonia, Argentina, suggest that vegetation in South America suffered great losses but rebounded quickly, according to an international team of researchers.
PROVIDENCE, R.I. [Brown University] -- Last month, Japan's Hayabusa2 mission brought home a cache of rocks collected from a near-Earth asteroid called Ryugu. While analysis of those returned samples is just getting underway, researchers are using data from the spacecraft's other instruments to reveal new details about the asteroid's past.
DURHAM, N.C. -- Self-control, the ability to contain one's own thoughts, feelings and behaviors, and to work toward goals with a plan, is one of the personality traits that makes a child ready for school. And, it turns out, ready for life as well.
In a large study that has tracked a thousand people from birth through age 45 in New Zealand, researchers have determined that people who had higher levels of self-control as children were aging more slowly than their peers at age 45. Their bodies and brains were healthier and biologically younger.
A clear view of anatomical structures is vital for the success of surgery--especially in microsurgery where narrow anatomical cavities or proximity to vulnerable organs and tissues can pose significant risks to patient health. The surgical microscope has evolved to become a powerful tool for improving surgical visualization.
TROY, N.Y. -- A loss of enzymatic processes within the body can increase a person's risk of bone fracture. This new insight was recently published in eLife by an international team of scientists and engineers led by Deepak Vashishth, the director of the Center for Biotechnology and Interdisciplinary Studies (CBIS) at Rensselaer Polytechnic Institute.
Worldwide, marine megafauna are at risk of extinction due to climate change, habitat loss, pollution, overhunting, population fragmentation, and hybridization with related species in areas disturbed by humans. Genetic studies can help determine the conservation status of marine animals, identifying threats to species conservation and informing interventions and policies, such as the protection of diversity hotspots or corridors for gene flow.
CHAMPAIGN, Ill. -- A small portion of scientific papers are retracted for research that is in error or fraudulent. But those papers can continue to be cited by other scientists in their work, potentially passing along the misinformation from the retracted articles.
Hotel managers have something in common beyond their reputations for charming dispositions and excellent listening skills - they're predominantly men, despite women making up the majority of the accommodations workforce. New research led by the University of Houston Conrad N. Hilton College of Hotel and Restaurant Management suggests hotel companies that promote a woman over an equally qualified man are perceived as fairer and less discriminatory, creating a stronger organizational culture and higher financial performance.
BOSTON -- Getting control of COVID-19 will take more than widespread vaccination; it will also require better understanding of why the disease causes no apparent symptoms in some people but leads to rapid multi-organ failure and death in others, as well as better insight into what treatments work best and for which patients.
