NewsResearchers test far-ultraviolet light to prevent bird flu in poultry
Researchers are preparing to test a new potential line of defense against highly pathogenic avian influenza, HPAI in poultry farming. They will use a form of ultraviolet light called far-UVC, to see if it can kill HPAI, without harming birds on poultry farms.

NewsLab identifies gap in malaria vaccines, added peptides can strengthen response
The two vaccines in use today rally the immune system against a single region of the malaria parasite. A new study finds that adding short peptides for two overlooked regions broadens the response and strengthens protection.

NewsScientists solve decades-old mystery of how malaria parasites invade human cells
Researchers have caught the malaria parasite’s moving junction in the act, obtainingg the first high-resolution view of its three-dimensional structure. It turns out to be a molecular machine that actively remodels the host cell’s membrane to help the parasite force its way inside.

NewsTime for an AI checkup: Flaw found in machine learning for sepsis treatment
Researchers found a flaw in many peer-reviewed studies using the AI method known as reinforcement learning as a theoretical guide for the treatment of sepsis. If these flawed systems for sepsis treatment were deployed in a healthcare setting, they would recommend either overtreatment or undertreatment in nearly half of patient states.

NewsHeart health may have impacted the risk of severe COVID-19 infection during the pandemic
Adults with highest heart health scores at the beginning of the pandemic were nearly half as likely to be hospitalized or die from COVID-19 when compared to those with the lowest scores, according to new research.

NewsBeyond outbreaks: zoonotic disease prevention at the human–animal interface in China
A study synthesizes evidence on 93 zoonotic diseases currently monitored by China’s public health, agricultural, and forestry sectors, and argues that meaningful risk reduction will require shifting from reactive outbreak response toward earlier prevention at the human–animal–environment interface.

NewsStudy reveals genome-wide host–virus genetic interactions in cancer risk
Researchers report a major advance in understanding how interactions between human and viral genomes shape disease risk. They found that variations in the Epstein–Barr virus, together with a specific immune-related gene (HLA-A*11:01), strongly influence the risk of nasopharyngeal cancer.

NewsA new mouse model of virus-driven liver cancer may open the door to better diagnosis and treatments
Researchers have created the first mouse model in which chronic viral infection progresses to liver cancer, closely mirroring what happens in people with hepatitis C.

NewsRNA-guided CRISPR system activates gene expression
In back-to-back studies, researchers report a naturally evolved gene-editing system that can activate genes, offering an advantage over existing CRISPR gene-editing systems that merely find and cut DNA.

News58% of patients affected by 2022 mpox outbreak report lasting physical symptoms
A cohort study found that more than half of those diagnosed with mpox during the 2022 outbreak still had lingering physical effects 11 to 18 months later.

NewsBats identified as origin of unexplained acute respiratory illness and encephalitis in Bangladesh
Infectious disease researchers have identified Pteropine orthoreovirus (PRV), an emerging bat-borne orthoreovirus, in archived throat swab samples and virus cultures from five patients in Bangladesh who were initially suspected to have Nipah virus infection but tested negative.

News Lack of dietary iron may impair immune cells’ ability to fight influenza
New research suggests that a lack of dietary iron can negatively affect the ability of immune cells to respond to viral infection in the lungs. In mice with dietary iron deficiency and influenza, immune cells struggled to produce a key signal needed to fight viruses and did not regain this ability.

NewsScientists use computer model to improve hospitals’ ability to limit spread of drug-resistant infections
The computer model improves on traditional methods like contact tracing by inferring asymptomatic carriers in the spread of antibiotic-resistant infections.

NewsStudy uncovers origins of urban human-biting mosquito, shedding light on uptick in West Nile virus spillover from birds to humans
The research disproves the theory that the mosquito evolved in the London underground by dating the mosquito’s origin back over 1,000 years and identifies the genetic links between bird-biting and human-biting mosquitoes, key to West Nile transmission.

NewsNew insights into malaria could reshape treatment
A sodium pump essential to the malaria parasite’s survival, PfATP4, has emerged as one of the most attractive drug targets. A new study presents the first high-resolution 3D structure of PfATP4 and identifies a previously unknown but essential binding partner.

NewsAntiviral treatment fails to slow early-stage Alzheimer’s
A clinical trial has found that a common antiviral for herpes simplex infections, valacyclovir, does not change the course of the disease for patients in the early stages of Alzheimer’s.

NewsFoot traffic can predict COVID-19 spread in New York City neighborhoods
A new study reveals how foot traffic data from mobile devices can enhance neighborhood-level COVID-19 forecasts in New York City, providing a novel approach to predicting the spread of the SARS-CoV-2 virus and improving targeted public health interventions.

NewsBiotin may shield brain from manganese-induced damage, study finds
New research showing the mechanisms by which manganese inflicts damage to the central nervous system suggests that the vitamin biotin - synthesized by gut bacteria - may have a protective effect, potentially mitigating manganese-induced damage.

NewsA new approach to predicting malaria drug resistance
Researchers analyzed the genomes of hundreds of malaria parasites to determine which genetic variants are most likely to confer drug resistance.

NewsStudy reveals vaccination patterns among LGBTQ+ adults in New Jersey and New York
A new study led by Rutgers Health researchers has uncovered important insights into vaccination patterns among LGBTQ+ adults in New Jersey and New York. The findings shed light on disparities in vaccine uptake within this diverse population.
