Medication to reduce ovarian scarring helps extends overall health of reproductive system Freezing eggs only addresses age-related infertility, not ovarian hormone loss. New treatment would ‘fix the root of the issue’ Findings also have implications for developing treatments for ovarian cancer CHICAGO --- A woman’s ovaries are like a factory where eggs grow and produce hormones that regulate everything from menstruation and pregnancy to bone density and mood. As she and her factory age, production dwindles, and by the time she hits menopause ...

Osaka, Japan – While the link between diabetes and periodontal disease is known, the impact of diabetes treatment on periodontal health is less well understood. Recent research published in Diabetes, Obesity and Metabolism demonstrates that periodontal inflammation can be positively affected just by receiving intensive diabetes treatment. It is widely believed that there is an interrelationship between diabetes and periodontal disease. While it has been shown that treatment of periodontal disease improves blood ...

University of Arizona researchers have developed a new biological sensing method that can detect substances at the zeptomolar level – an astonishingly miniscule amount. This level of sensing, immediately useful for drug testing and other research, has the potential to make new drug discoveries possible. Eventually, the advance could lead to portable sensors that can detect environmental toxins or chemical weapons, monitor food quality or screen for cancer.  A paper describing the results was published in the journal Nature Communications on Aug. 28. Judith Su, associate professor of biomedical engineering and optical ...

The most endangered plant species in the Mariana Islands, the legume tree Serianthes nelsonii, faces persistent threats in its recovery. These have been identified as a short lifespan of habitat seedlings and rapid death of saplings transplanted from conservation nurseries. The Plant Physiology Laboratory at the University of Guam addressed this conundrum by improving growth and survival of Serianthes seedlings through strategically placed mirrors beneath deeply shaded seedlings to increase available ambient light. The resulting paper has been published ...

Key takeaways The cumulative adversity index for people quantifies numerous measures of hardship, such as poverty and stress to understand health and longevity over the individual’s lifespan. A similar tool could help scientists who study and want to conserve animal populations by identifying the most influential stressors to mitigate. UCLA biologists have created the first cumulative adversity index for yellow-bellied marmots. They found that as in humans, adversity early on had lifelong consequences and reduced their life expectancy. Adversity early in life can have permanent health consequences for people — even if their circumstances improve dramatically later on. ...

In IVF treatment, embryos are traditionally transferred in the uterus three days after fertilization. Due to improvements in laboratory techniques, this is now also possible after five days. It was assumed that this increases the chance of a successful pregnancy. A study by Radboud university medical center and Amsterdam UMC shows that the day of transfer does not influence the success rate of the IVF trajectory. One out of thirty children in the Netherlands is conceived via in vitro fertilization, or IVF for short. In this procedure, ...

Renewable energy sources like wind and solar are critical to sustaining our planet, but they come with a big challenge: they don't always generate power when it's needed. To make the most of them, we need efficient and affordable ways to store the energy they produce, so we have power even when the wind isn't blowing or the sun isn't shining. Columbia Engineering material scientists have been focused on developing new kinds of batteries to transform how we store renewable energy. In a new study published September 5 by Nature Communications, the team used K-Na/S batteries that combine inexpensive, readily-found elements -- ...

Stanford researchers have developed an artificial intelligence-based tool – dubbed SandAI – that can reveal the history of quartz sand grains going back hundreds of millions of years. With SandAI, researchers can tell with high accuracy if wind, rivers, waves, or glacial movements shaped and deposited motes of sand. The tool gives researchers a unique window into the past for geological and archeological studies, especially for eras and environments where few other clues, such as fossils, are preserved ...

Scientists have discovered that certain plants can survive stressful, dry conditions by controlling water loss through their leaves without relying on their usual mechanism - tiny pores known as ‘stomata’.    Nonstomatal control of transpiration in maize, sorghum, and proso millet – all C4 crops which are critical for global food security – gives these plants an advantage in maintaining a beneficial microclimate for photosynthesis within their leaves.   This allows the plants to absorb carbon dioxide ...
