Brain activity foreshadows changes in stock prices

Activity in the brains' risk circuits can forecast changes in stock prices

Brain activity foreshadows changes in stock prices
2021-03-08
(Press-News.org) Forecasting changes in stock prices may be possible with the help of brain activity in regions associated with how people feel before making investment choices. Scientists could accurately forecast market price changes based on the average brain activity among a group but failed when using only prior stock trends or people's investment choices, according to new research published in JNeurosci.

Scientists have used the average brain activity among a group to predict which videos will go viral and which crowdfunding campaigns will receive funding. In a new study, Stallen et al. investigated if this relationship extends to a more complex and dynamic arena: the stock market.

Participants examined real stock price trends from 2015 as they decided if they wanted to buy or sell the displayed stocks. During the task, the researchers used fMRI to measure activity in the nucleus accumbens and anterior insula, areas involved in seeking reward and avoiding risk, respectively. Using the group's average brain activity in these regions, the researchers could forecast how a stock would behave. Increased nucleus accumbens activity forecast when a stock's price would increase the next day, while increased anterior insula activity forecast when it would flip or change direction. Prior stock market trends and the participants' own investing choices could not forecast stock price dynamics.

New discovery explains antihypertensive properties of green and black tea

New discovery explains antihypertensive properties of green and black tea
2021-03-08
Irvine, CA - March 8, 2021 - A new study from the University of California, Irvine shows that compounds in both green and black tea relax blood vessels by activating ion channel proteins in the blood vessel wall. The discovery helps explain the antihypertensive properties of tea and could lead to the design of new blood pressure-lowering medications. Published in Cellular Physiology and Biochemistry, the discovery was made by the laboratory of Geoffrey Abbott, PhD, a professor in the Department of Physiology and Biophysics at the UCI School of Medicine. Kaitlyn Redford, a graduate student in the Abbott Lab, was first author of the study titled, "KCNQ5 potassium channel activation underlies vasodilation by tea." Results from the research revealed that two catechin-type ...

Sophisticated skin

2021-03-08
Squids have long been a source of fascination for humans, providing the stuff of legend, superstition and myth. And it's no wonder -- their odd appearances and strange intelligence, their mastery of the open ocean can inspire awe in those who see them. Legends aside, squids continue to intrigue people today -- people like UC Santa Barbara professor Daniel Morse -- for much the same, albeit more scientific, reasons. Having evolved for hundreds of millions of years to hunt, communicate, evade predators and mate in the vast, often featureless expanses of open water, squids have developed some of the most sophisticated skin in the animal kingdom. "For centuries, people have been amazed at the ability of squids to change the color and patterns of their skin -- which they ...

Assessing regulatory fairness through machine learning

Assessing regulatory fairness through machine learning
2021-03-08
The perils of machine learning - using computers to identify and analyze data patterns, such as in facial recognition software - have made headlines lately. Yet the technology also holds promise to help enforce federal regulations, including those related to the environment, in a fair, transparent way, according to a new study by Stanford researchers. The analysis, published this week in the proceedings of the Association of Computing Machinery Conference on Fairness, Accountability and Transparency(link is external), evaluates machine learning techniques designed to support a U.S. Environmental Protection Agency (EPA) initiative to reduce ...

Rise of marine predators reshaped ocean life as dramatically as sudden mass extinctions

Rise of marine predators reshaped ocean life as dramatically as sudden mass extinctions
2021-03-08
GAINESVILLE, Fla. --- Evolutionary arms races between marine animals overhauled ocean ecosystems on scales similar to the mass extinctions triggered by global disasters, a new study shows. Scientists at Umeå University in Sweden and the Florida Museum of Natural History used paleontological databases to build a multilayered computer model of the history of marine life over the last 500 million years. Their analysis of the fossil record closely echoed a seminal 1981 study by paleontologist J. John Sepkoski - with one key difference. Sepkoski's ground-breaking statistical work showed abrupt ocean-wide changes in biodiversity about 490 and 250 ...

Oncotarget: Sensitivity testing on ovarian cancer cells isolated from malignant ascites

Oncotarget: Sensitivity testing on ovarian cancer cells isolated from malignant ascites
2021-03-08
Oncotarget published "Chemotherapy sensitivity testing on ovarian cancer cells isolated from malignant ascites" which reported that the authors aim is to determine the feasibility of cell proliferation assays of tumor cells isolated from malignant ascites to predict in vitro chemotherapy sensitivity, and to correlate these results with clinical outcome. Cell samples were enriched for tumor cells and EOC origin was confirmed by intracellular staining of CK7, surface staining of CA125 and EpCAM, and HE4 gene expression. In vitro sensitivity to chemotherapy was determined in cell proliferation assays using intracellular ATP content as an indirect measure of cell number. In twelve of ...

Oncotarget: High-fat ovariectomized mice susceptible to accelerated tumor growth
2021-03-08
Oncotarget published "High-fat diet-fed ovariectomized mice are susceptible to accelerated subcutaneous tumor growth potentially through adipose tissue inflammation, local insulin-like growth factor release, and tumor associated macrophages" which reported that the association between obesity and colorectal cancer (CRC) risk has been well established. This relationship appears to be more significant in men than in women, which may be attributable to sex hormones - controlled animal studies to substantiate these claims and the mechanisms involved are lacking. MC38 murine colon adenocarcinoma ...

2021-03-08
Oncotarget recently published "Estrogen receptor α polymorphism is associated with dementia in a Brazilian cohort" which reported that the growth of the elderly population is a worldwide phenomenon and it is associated with chronic diseases, including dementia. In this scenario, the present study aimed to evaluate a possible association of estrogen receptor α polymorphisms with dementia in a Brazilian cohort. The genotyping for the ERα PvuII and XbaI polymorphisms were performed by polymerase chain reaction-restriction fragment length polymorphism. The ERα PvuII pp genotype was associated with a higher odds ratio for dementia (OR = 3.42, 95% CI = 1.33-8.77, p = 0.01, ...
