Collecting large-scale data from impoverished communities
New study showcases the feasibility of creating low-cost, scalable neuroimaging programs in low- and middle-income countries without compromising data quality.

(Press-News.org) People are diverse, and the environments they live in may influence them differently. This broad diversity increases the need for neuroimaging studies that collect data from large communities. In a new eNeuro paper, Tara Thiagarajan, from Sapiens Labs, and colleagues showcase the feasibility of going to low- and middle-income communities and collecting large-scale, high-quality data.
In their paper, the authors share the methods they used to create two ongoing data acquisition programs in India and Tanzania. These programs provide nonspecialist training, structured teams, and automated data quality monitoring. So far, the programs have collected data from 7,933 participants over a period of 30 weeks. Not only is the data quality comparable to datasets from controlled lab settings, but test subject costs are also substantially lower, demonstrating the cost effectiveness of the programs.
This study highlights the potential for implementing scalable neuroimaging research in low- and middle-income countries that previously was not possible. While the data from this study are not currently openly shared, the researchers have a goal of sharing their data in real time on a day-to-day basis by 2026. Adds Thiagarajan, “This work opens up a new way of understanding humanity and how the environment is shaping human beings.”

In a new JNeurosci paper, Julie Royo, from the Institute of Cerveau, and colleagues explored the neuroanatomy that underlies social dominance in nonhuman primates.
The researchers focused on brain tracts associated with human emotion, motivation, and memory as they assessed structural brain properties and behavioral measures of social dominance in 15 squirrel monkeys. These behavioral measures were related to hierarchy, aggression, and submission. Royo and colleagues found that one of the brain tracts they focused on—the uncinate fasciculus—highly correlated with their social dominance measures. This correlation was particularly true for the uncinate fasciculus ...

A near-complete genomic framework of wild Oryza species now provides insights into the evolution of the genus and offers new avenues for crop improvement and conservation efforts[1].
The Oryza genus, containing related species of plants in the grass family, provides the world with one of the most important domesticated grain crops: rice. Oryza includes the Asian and African cultivated rice species (O. sativa and O. glaberrima), as well as 26 species of wild rice, which offer a rich, untapped source ...

Wastewater surveillance became a popular choice among public health officials looking to track rapid virus mutations and spread patterns during the COVID-19 pandemic. But what if there was a way to detect emerging viruses even faster — or to even sniff out new variants possibly before patients even realize they’re ill?
A new UNLV-led study is moving that dream one step closer to reality by pairing wastewater sample surveillance with artificial intelligence. The results appear in the latest issue of the ...

The modulation of the surface structure of platinum-based single-atom alloys is crucial for improving the catalytic performance in propane dehydrogenation. The optimization of the surface structure of PtCu clusters was attained through regenerative treatment, which significantly improved the propylene yield and catalytic stability, thereby offering a viable strategy for the design of alloy catalysts applicable to various high-temperature dehydrogenation reactions.
A research team, directed by Prof. Guangxu Chen at South China University of Technology in Guangdong, China, recently published a study on the utilization of regenerative treatment ...

Betelgeuse is one of the brightest stars in the night sky, and the closest red supergiant to Earth. It has an enormous volume, spanning a radius around 700 times that of the Sun. Despite only being ten million years old, which is considered young by astronomy standards, it’s late in its life. Located in the shoulder of the constellation Orion, people have observed Betelgeuse with the naked eye for millennia, noticing that the star changes in brightness over time. Astronomers established that Betelgeuse has a main period of variability of around 400 days and a more extended secondary period of around six years.
In 2019 and 2020, ...

Hollow, pumpkin-shaped molecules can efficiently separate valuable hydrocarbons from crude oil, KAUST researchers have shown[1]. These ‘molecular sieves’, known as cucurbiturils, could enable a more sustainable approach to producing raw materials for the chemicals industry.
Crude oil is a complex mixture of hydrocarbons vital for almost every aspect of life, from fuels to plastics. Cyclohexane, for example, is used in nylon production, but isolating it at sufficient purity typically involves multiple energy-intensive fractional distillation steps.
The KAUST team has now developed an alternative separation strategy based on cucurbiturils, named for their ...

Near-infrared (NIR) spectroscopy is a powerful technique for probing molecular compositions and structures non-invasively. However, traditional NIR spectrometers are often bulky and expensive, limiting their applications in portable or resource-constrained settings. A team of researchers from Huazhong University of Science and Technology (HUST) has addressed this challenge by developing a miniaturized NIR computational spectrometer using PbS quantum dots (QDs). Their work, published in Nano Research, demonstrates how finely-tuned QDs can achieve a spectral resolution of 1.5 nm, a significant improvement over previous works.
Why is this study important? NIR ...

The efficacy of CAR-T cells in ablating solid tumors is significantly impeded by the densely packed tumor extracellular matrix (ECM). This physical barrier severely restricts CAR-T cell infiltration within the tumor, thereby inhibiting their immunogenicity and antitumor response. While combining CAR-T with hyaluronidase (HAase) to reduce ECM is apparent, the efficacy is limited because of low accumulation and penetration efficiency of HAase inside the tumor tissue.

With the rapid development of modern society and the increasing popularity of electronic equipment, electromagnetic wave pollution has become a serious problem. In order to solve this problem, the research and application of electromagnetic absorbing materials have been widely concerned. In recent years, the construction of heterogeneous absorbing materials with different components has become a major research focus. The heterogeneous structure formed by hard magnetic and soft magnetic materials can produce interfacial exchange coupling at the heterogeneous interface. However, there are few researches on soft and hard heterostructures ...

Alkaline water splitting has the advantages of low cost, long lifetime and ease of maintenance, and is widely applied commercially. However, the sluggish kinetics of HER inhibits the further development of alkaline water splitting. Though noble catalysts can greatly boost the process of HER, they are hard to meet the requirement of industrial production due to the high price and scarcity. Thus, it is urgent to develop low cost and highly efficient catalysts for alkaline water splitting.
A team of material scientists led by Qiang Wang and Shuang Yuan from Northeastern University in Shenyang, China recently ...
