Researchers develop innovative tool for rapid pathogen detection
2025-03-04
(Press-News.org)
Researchers from the Zhang Liye Laboratory have developed a groundbreaking tool that revolutionizes the way researchers design primers for detecting pathogens. This new pipeline, which scans entire genomes to identify the most effective primer sets, could significantly enhance the speed and accuracy of diagnosing infectious diseases. The findings, published on 15 Feb 2025 in Frontiers of Computer Science, address a critical challenge in quantitative PCR (qPCR) primer design.
Unlike existing software that requires manual selection of specific genes or regions, this new tool automatically searches across the entire genome, making it easier for researchers to develop highly specific and sensitive tests for pathogens. By automating the process of primer design across whole genomes, the pipeline enabling faster, more accurate identification of disease-causing microorganisms, which could have far-reaching implications for public health. The team demonstrated the tool's effectiveness by designing primers to distinguish between two closely related fungal pathogens, Cryptococcus gattii and Cryptococcus neoformans. In laboratory tests, the primers showed remarkable specificity, amplifying only the target pathogens while avoiding false positives from nine other control species.This innovation comes at a crucial time, as the global community continues to grapple with the challenges of rapidly evolving pathogens. The researchers believe their tool could be particularly valuable for designing primers for viruses and fungi, potentially accelerating the response to emerging infectious diseases.The pipeline is freely available as a Python package, allowing researchers worldwide to access and utilize this powerful new resource. As the scientific community embraces this tool, it could lead to faster, more accurate diagnostic tests, ultimately improving patient care and public health outcomes.

Research into immunotherapy against cancer typically focuses on better recognition of cancer cells by the body's own immune system. Researchers at Amsterdam UMC and Moffitt Cancer Center have taken a different approach. They investigated how cancer affects the energy management of a patient’s T cells and showed for the first time that contact with chronic lymphocytic leukaemia (CLL) cells leads to a serious energy crisis in these cells. These findings are published today in Cellular & Molecular Immunology, building on a publication earlier this month in Blood Advances. ...

The sexual abuse of children affects 15 percent of girls and 8 percent of boys worldwide, incurring high public costs and devastating consequences for its survivors. In the United States, at least one in four girls and one in 20 boys experience sexual abuse. A US Preventive Services Task Force report recently concluded there’s not enough evidence that prevention is effective.
Now, a new study published in JAMA Pediatrics provides the missing evidence that coordinated, community-wide primary prevention efforts can significantly reduce child sexual abuse rates. The counties in the study that received the educational measures ...

Obesity rates are set to skyrocket, with one in six children and adolescents worldwide forecast to be obese by 2050, according to a new study. But with significant increases predicted within the next five years, the researchers stress urgent action now could turn the tide on the public health crisis.
The research, led by Murdoch Children’s Research Institute (MCRI) and published in The Lancet, found a third of children and adolescents will be overweight (385 million) or obese (360 million) within the next 25 years. The forecast equates ...

The use of tocolytic drugs in cases of threatened premature birth after 30 weeks of pregnancy does not improve the baby’s health. This is shown by the largest study concerning the effectiveness of tocolytic drugs on the health of babies, led by Amsterdam UMC, the results of which were published today in The Lancet.
Worldwide, 1 in 10 pregnancies result in premature birth. Children born prematurely face a higher risk of mortality and serious health problems, both in the short and long term. As a results, tocolytic drugs have been used a standard treatment for many ...

Nearly 1 in 5 college athletes reports some form of abusive supervision—defined as sustained hostile verbal and non-verbal behaviours—by their coaches, reveals an analysis of survey responses, involving National Collegiate Athletic Association (NCAA) athletes, and published online in the British Journal of Sports Medicine.
While there is no evidence of vulnerability according to race/ethnicity, sexual orientation, or gender, athletes with disabilities and those participating in team sports seem to be most at risk, the findings indicate.
Athletes view their coaches as role models, which makes their interactions susceptible ...

**Study includes country-level data for 204 countries and territories worldwide. A link to summary tables for rates in selected countries as well as country-level data is included at the end of the press release**
Most comprehensive global analysis to date estimates that overweight and obesity rates in adults (aged 25 or older) and children and adolescents (aged 5-24 years) more than doubled over the past three decades (1990-2021), affecting 2.11 billion adults and 493 million young people worldwide in 2021.
Weight gain varies widely across the globe with more than half ...

AMES, Iowa – The amount of nitrogen fertilizer needed to maximize the profitability of corn production in the Midwest has been increasing by about 1.2% per year for the past three decades, according to new Iowa State University research.
The study, published last month in Nature Communications, analyzed data from prior long- and short-term studies by Iowa State and the University of Illinois to calculate the Corn Belt’s steadily rising optimum nitrogen rates, which researchers had thought were static ...

ANN ARBOR—Hydrogen has the potential to power internal combustion engines, including on-road and off-road vehicles and equipment, and large marine engines. Despite its promise to reduce climate change emissions such as carbon dioxide and harmful pollutants, hydrogen has largely remained underutilized in the United States.
Officials at the University of Michigan and University of California, Riverside, along with several industry partners, are working to change that with the launch of the Hydrogen Engine Alliance of North America, or H2EA-NA. ...
