Fetal brain impacted when mom fights severe flu: New mouse study explains how      (via sciencedaily.com)     Original source 

New research using live mouse-adapted influenza virus improves upon previous mouse experiments to explain how maternal infection impacts fetal brain development. The study also indicates fetal brain changes are more likely once the severity of the mother's infection meets a specific threshold.

From genes to jeans: New genetic insights may lead to drought resilient cotton      (via sciencedaily.com)     Original source 

Cotton is woven into the very fabric of our lives, from soft T-shirts to comfortable jeans and cozy bedsheets. It's the world's leading renewable textile fiber and the backbone of a global industry worth billions. As climate change intensifies, cotton farmers face increasing challenges from drought and heat. However, new research offers hope for developing more resilient varieties that can maintain high yields even under water-stressed conditions.

New progress in research into malignant catarrhal fever in cattle      (via sciencedaily.com)     Original source 

A research team has published a groundbreaking study on malignant catarrhal fever (MCF). This disease is caused by the alcelaphine gammaherpesvirus 1 (AlHV-1), which infects its natural host, the wildebeest. This study sheds light on the mechanisms by which this virus, which is asymptomatic and latent in the wildebeest, causes an oligoclonal expansion of CD8+ T lymphocytes in cattle, leading to the development of MCF.

Researchers decipher new molecular mechanisms related to biological tissue regeneration      (via sciencedaily.com)     Original source 

A study opens new perspectives to better understand how the molecular mechanisms involved in regenerative medicine work. The study focuses on tumor necrosis factor- (TNF- ) and its receptors TNFR, molecules of key interest in biomedicine due to their involvement in multiple diseases such as obesity related to type 2 diabetes mellitus, inflammatory bowel disease and several types of cancer.

Virus that causes COVID-19 is widespread in wildlife, scientists find      (via sciencedaily.com)     Original source 

SARS-CoV-2, the virus responsible for COVID-19, is widespread among wildlife species, according to new research. The virus was detected in six common backyard species, and antibodies indicating prior exposure to the virus were found in five species, with rates of exposure ranging from 40 to 60 percent depending on the species.

New understanding of fly behavior has potential application in robotics, public safety      (via sciencedaily.com)     Original source 

Scientists have identified an automatic behavior in flies that helps them assess wind conditions -- its presence and direction -- before deploying a strategy to follow a scent to its source. The fact that they can do this is surprising -- can you tell if there's a gentle breeze if you stick your head out of a moving car? Flies aren't just reacting to an odor with a preprogrammed response: they are responding in context-appropriate manner. This knowledge potentially could be applied to train more sophisticated algorithms for scent-detecting drones to find the source of chemical leaks.

Fresh light on the path to net zero      (via sciencedaily.com)     Original source 

Researchers have used magnetic fields to reveal the mystery of how light particles split. Scientists are closer to giving the next generation of solar cells a powerful boost by integrating a process that could make the technology more efficient by breaking particles of light photons into small chunks.

In clinical trial, fecal matter transplant helped half of patients with gastrointestinal cancers overcome resistance to immunotherapy treatment      (via sciencedaily.com)     Original source 

Findings from a small, proof-of-concept clinical trial have suggested that fecal microbiota transplants (FMTs) can boost the effectiveness of immunotherapy in a range of gastrointestinal cancers. In the study, six of 13 patients who had previously shown resistance to immune checkpoint inhibitors benefited from receiving FMTs from donors who had previously responded to treatment. The investigators also identified specific strains of bacteria associated with better or worse responses to FMT and immune checkpoint drugs.

How a bacterium supports healing of chronic diabetic wounds      (via sciencedaily.com)     Original source 

New research shows that a certain bug, Alcaligenes faecalis (A. faecalis), can facilitate healing of hard-to-treat wounds among people with diabetes. While there are many studies done on potentially harmful bacteria in wounds, the researchers discovered that A. faecalis, a bacterium found in many types of chronic wounds, actually boosts healing of diabetic wounds. The researchers found that the beneficial bacterium can promote skin cell movements that are essential for wound closure by inhibiting enzymes that are over-produced in people with diabetes.
