(Press-News.org) Because nitrogen fertilizers contribute to global greenhouse gas emissions, scientists are looking for ways to modify agricultural plants so that they rely on less nitrogen. In research published in New Phytologist, investigators have found that blocking a particular protein may achieve this goal in potatoes.
The protein, called Solanum tuberosum CYCLING DOF FACTOR 1 (StCDF1), binds to DNA and plays a key role in regulating tuberization in potatoes. In this latest research, investigators found that StCDF1 modulates nitrogen-related gene expression. Blocking StCDF1 improved plant performance in low nitrogen environments.
“Natural variation in StCDF1 binding to the single potato NITRATE REDUCTASE gene emerges as a promising strategy to reduce potato needs of nitrogen fertilizers, as this gene encodes a limiting step for nitrate reduction and later assimilation,” said co–corresponding author Salomé Prat, Research Professor, of the Centre for Research in Agricultural Genomics, in Spain.

Do commercial ties influence ESG ratings?
2024-11-06
An analysis published in the Journal of Accounting Research uncovers evidence that conflicts of interest arising from commercial ties lead to bias in environmental, social, and governance (ESG) ratings.
Investigators focused on Moody’s and S&P’s acquisitions of ESG rating agencies Vigeo Eiris and RobecoSAM. Their analysis revealed that after these ESG rating agencies were acquired by Moody’s and S&P, they issued higher ratings to existing paying clients of Moody’s and S&P. Specifically, ...
Study assesses "gendered space" in financial institutions in Pakistan
2024-11-06
In Islamic cultures, purdah, which literally means “curtain,” is a practice that involves the seclusion of women from public observation and the enforcement of high standards of female modesty. Research published in the Journal of Management Studies examines the significance of purdah (spatial modesty) in gender relations in financial institutions in Pakistan.
The research was based on the lived experiences of women and men working in two banks based in Pakistan. One of the study’s co-authors, Shafaq Chaudhry, PhD, of the University of Central Lancashire, in the UK, sought internships for six weeks ...
Chinese herbal medicine’s potential in preventing dementia
2024-11-06
Attempts to discover a breakthrough dementia drug might be drawing attention these days, but traditional medicinal products can offer hints for preventive medicine.
A research group led by Specially Appointed Professor Takami Tomiyama of Osaka Metropolitan University’s Graduate School of Medicine has found that administering the dried seeds of a type of jujube called Ziziphus jujuba Miller var. spinosa, used as a medicinal herb in traditional Chinese medicine, holds promise in restoring cognitive and motor function in model mice.
By administering hot water extracts of Zizyphi spinosi semen to model mice with ...
Firms that read more perform better
2024-11-06
[Vienna, November 6, 2024] — “Tell me how you read and I’ll tell you who you are.” By analyzing online reading behavior across millions of firms worldwide, a new study out of the Complexity Science Hub (CSH) connects how much information companies consume and how the consumption relates to their size.
"The way companies consume information is reminiscent of biological organisms. They take in, transmit, and transform information to make decisions. As with organisms, there are important size differences. Larger firms tend to consume information more efficiently ...
Tightly tied waist cord of saree underskirt may pose cancer risk, warn doctors
2024-11-06
A tightly tied waist cord of the underskirt (petticoat) traditionally worn under a saree, particularly in rural parts of India, may lead to what has been dubbed ‘petticoat cancer,’ warn doctors in the journal BMJ Case Reports after treating two women with this type of malignancy.
The continued pressure and friction on the skin can cause chronic inflammation, leading to ulceration, and, in some cases, progression to skin cancer, say the authors.
This phenomenon has previously been described as “saree cancer,” but it is the tightness of the waist cord that’s to blame, ...

10% of Children in High-Burden Tuberculosis Settings May Develop the Disease by Age 10
New findings also indicate that children who live in settings with a high burden of TB have a consistently high annual risk of developing TB infection throughout childhood.
An estimated 1.2 million children develop tuberculosis disease (TB) and 200,000 kids die from TB worldwide each year, but the risk of developing TB infection and disease throughout childhood remains under-studied. Furthermore, the majority of studies on the pediatric burden of TB are informed by data ...
Health experts push for the elimination of a ‘remarkably harmful toxin’
2024-11-06
The Biden administration’s recently announced plan to replace all lead pipes in the U.S. is a reminder that the toxic metal remains a threat, even in a country that has largely banned its use. The smallest levels of lead exposure can cause a range of health damages over time, especially to children’s brain development. Stanford researchers Stephen Luby and Jenna Forsyth have spent years examining the widespread presence of lead in low-income countries, including in some commonly consumed products. They led a perspective published Nov. 5 in The Lancet Public Health that tallies lead’s global ...

The University of Tennessee, Knoxville, and defense technology company Lockheed Martin announced the signing of a new five-year master research agreement Oct. 31, reinforcing a longstanding partnership that helps UT take its research capabilities from the lab to the field.
“This partnership allows UT researchers to conduct true translational research,” said James Andes, director of national security research initiatives for UT. “Our research concepts are matured by working with technical champions at Lockheed Martin, and as a ...
Testing thousands of RNA enzymes helps find first ‘twister ribozyme’ in mammals
2024-11-05
UNIVERSITY PARK, Pa. — The “RNA world” hypothesis proposes that the earliest life on Earth may have been based on RNA — a single-stranded molecule similar in many ways to DNA — like some modern viruses. This is because, like DNA, RNA can carry genetic information, but, like a protein, it can also act as an enzyme, initiating or accelerating reactions. While the activity of a few RNA enzymes — called ribozymes — have been tested on a case-by-case basis, there are thousands more that have been computationally predicted to exist in organisms ranging from bacteria to plants and animals. Now, ...
Groundbreaking study provides new evidence of when Earth was slushy
2024-11-05
At the end of the last global ice age, the deep-frozen Earth reached a built-in limit of climate change and thawed into a slushy planet.
Results from a Virginia Tech-led study provide the first direct geochemical evidence of the slushy planet — otherwise known as the “plumeworld ocean” era — when sky-high carbon dioxide levels forced the frozen Earth into a massive, rapid melting period.
“Our results have important implications for understanding how Earth's climate and ocean chemistry changed after the extreme conditions of the last global ...
