Neuroscientists shed light on causes of postpartum depression using new research model
Postpartum depression strikes nearly one in five new mothers. Stress is a significant risk factor for this complex condition. Tufts University neuroscientists have generated a novel preclinical model of postpartum depression and demonstrated involvement of the hypothalamic-pituitary-adrenal axis (the neuroendocrine system that mediates physiological response to stress and is normally suppressed during and after pregnancy). These findings in mice provide the first empirical evidence that disruption of this system engenders behaviors mimicking human postpartum depression.
Befriending oneself has benefits, but backup plan recommended
A self-replicating fish replicates only its own DNA, but researchers have found the mangrove killifish has a remarkable amount of genetic diversity across its species.
New laws increase access to healthcare delivery for advanced practice registered nurses
As 2017 comes to a close, many states have enacted laws and regulations expanding access to healthcare provided by advanced practice registered nurses (APRNs), according to the 30th Annual Legislative Update in the January issue of The Nurse Practitioner, published by Wolters Kluwer.
The scientists from MSU developed a basis for highly sensitive gas sensors
A team from the Faculty of Physics of Lomonosov Moscow State University suggested using porous silicon nanowire arrays in highly sensitive gas sensors. These devices will be able to detect the presence of toxic and non-toxic gas molecules in the air at room temperature. The results of the study were published in Physica Status Solidi A: Applications and Materials Science journal.
Toward designing/controlling flexibility of MOFs
As one of the most important characteristics of porous coordination polymers or metal-organic frameworks (MOFs), framework flexibility is not only interesting but also useful. Although designing, tailoring, or controlling framework flexibility of MOFs is much more difficult than for static structural features such as the framework topology and pore size/shape, scientists based in China summarize the advances and in designing/controlling flexibility of MOFs, and provide strategies for future studies.
Scientists should be super modelers
Scholars and conservationists want to aim for the right future to preserve biodiversity and plan sustainable environments. One of those scholars is calling for due diligence to make sure the right data, not conventional wisdom, shapes that target.
Thermoelectric power generation at room temperature: Coming soon?
A research team led by Osaka University created a thermoelectric material with promising performance at room temperature. Ytterbium silicide is a good electrical conductor. It also has a high Seebeck coefficient thanks to Kondo resonance (fluctuation of f-electrons), which increases its power factor. Its layered structure further promotes the thermoelectric effect by blocking heat conduction. This non-toxic, room-temperature thermoelectric material is competitive with conventional bismuth telluride, and could be used for power generation or refrigeration.
Human influences have reduced the likelihood of record-breaking cold event in China
Collaborative efforts investigated the effect of anthropogenic forcings on the likelihood of record-breaking cold event in Eastern China.
A powerful guiding principle for topological quantum synthesis
The collaborative team of Prof. Huijun Liu at Wuhan University, Prof. Xingqiu Chen at the Institute of Metal Research, Chinese Academy of Sciences, and Prof. Zhenyu Zhang at the University of Science and Technology of China proposes an efficient criterion that allows ready screening of potential topological insulators, a powerful guiding principle in synthesizing topological quantum materials. The work has been published as a cover paper in 2017, Issue 24 of Science Bulletin.
A new strategy for efficient hydrogen production
An joint research team, affiliated with South Korea's Ulsan National Institute of Science and Technology (UNIST) has introduced the Hybrid-SOEC system with highest reported electrochemical performance in hydrogen production.
