Fear can be measured in the brain and fearful life-threatening events can leave quantifiable long-lasting traces in the neural circuitry of the brain with enduring effects on behaviour, as shown most clearly in post-traumatic stress disorder (PTSD).
A new study by Western University demonstrates that the fear predators inspire can leave long-lasting traces in the neural circuitry of wild animals and induce enduringly fearful behaviour, comparable to effects seen in PTSD research.
San Antonio, Texas (August 7, 2019) - Old lungs are not as capable as young lungs of fighting off an infection of the bacteria that causes tuberculosis (TB), placing seniors at a greater risk of developing TB. The microbe that causes this infectious disease, Mycobacterium tuberculosis (Mtb), currently kills more people in the world than any other pathogen.
With water scarcity a critical challenge across the globe, scientists and engineers are pursuing new ways to harvest purified water from unconventional sources, like seawater or even wastewater.
One of those researchers is Tiezheng Tong, an assistant professor in the Department of Civil and Environmental Engineering, whose lab is studying an emerging technology called membrane distillation.
Fruit flies could one day provide new avenues to discover additional genes that contribute to a person's ability to learn and remember. Scientists at the University of Missouri are studying genes of fruit flies to explore why an individual fly can be a better learner than another. Many of those genes in fruit flies are similar to those found in people.
PHOENIX, Ariz. -- Aug. 7, 2019 -- A new type of blood test for breast cancer could help avoid thousands of unnecessary surgeries and otherwise precisely monitor disease progression, according to a study led by the Translational Genomics Research Institute (TGen) and Mayo Clinic in Arizona.
TGen is an affiliate of City of Hope, which along with The Cancer Research UK Cambridge Institute at Cambridge University and the Biodesign Institute at Arizona State University (ASU) also contributed to this study.
Novel approaches that have been tested to treat obesity include noninvasive neuromodulation techniques such as transcranial direct current stimulation (tDCS). Studies performed to date have suggested that this method does in fact help reduce appetite, food intake and body weight, but only in some subjects.
Leesburg, VA, August 7, 2019--According to an ahead-of-print "Focus On" article published in the November issue of the American Journal of Roentgenology (AJR), collaborative research has not only standardized the definition of a complete imaging history, but also engineered systems to include supportive prompts in the order entry interface with a single keystroke--sustainably improving the quality of imaging histories, themselves.
Semiconducting polymers, very large chain-like molecules made from repeating sub-units, are increasingly drawing the attention of researchers because of their potential applications in organic electronic devices. Like most semiconducting materials, semiconducting polymers can be classified as p-type or n-type according to their conducting properties. Although p-type semiconducting polymers have seen dramatic improvements thanks to recent advances, the same cannot be said about their n-type counterparts, whose electron-conducting characteristics (or 'electron mobility') are still poor.
Small fishes play an important role in the marine food chain, providing food for larger fishes and water birds, but they are also caught for use as bait in both commercial and recreational fisheries. Over the past thirty years, a decline has been noted in some species of baitfish, leading scientists and resource managers to look more closely at the population dynamics of these important fish. However, baitfish tend to congregate in large schools containing multiple species, making it difficult to study individual populations.
DES PLAINES, IL -- Opioid use at the three-month follow-up in emergency department patients discharged with an opioid prescription for acute pain is relatively low and not necessarily synonymous with opioid misuse. That is the conclusion of a study to be published in the August 2019 issue of Academic Emergency Medicine (AEM), a journal of the Society for Academic Emergency Medicine (SAEM).
