Published Fetal brain impacted when mom fights severe flu: New mouse study explains how



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.
Published From genes to jeans: New genetic insights may lead to drought resilient cotton



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.
Published New progress in research into malignant catarrhal fever in cattle



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.
Published Scientists untangle interactions between the Earth's early life forms and the environment over 500 million years



The atmosphere, the ocean and life on Earth interacted over the past 500-plus million years in ways that improved conditions for early organisms to thrive. Now, an interdisciplinary team of scientists has produced a perspective article of this co-evolutionary history.
Published Healthy diet with less sugar is linked to younger biological age



Researchers have found a link between following a diet that is rich in vitamins and minerals, especially one without much added sugar, and having a younger biological age at the cellular level.
Published Researchers decipher new molecular mechanisms related to biological tissue regeneration



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.
Published Optical fibers fit for the age of quantum computing



A new generation of specialty optical fibers has been developed by physicists to cope with the challenges of data transfer expected to arise in the future age of quantum computing.
Published Virus that causes COVID-19 is widespread in wildlife, scientists find



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.
Published Lampreys possess a 'jaw-dropping' evolutionary origin



Lampreys are one of only two living jawless vertebrates Jaws are formed by a key stem cell population called the neural crest New research reveals the gene regulatory changes that may explain morphological differences between jawed and jawless vertebrates.
Published New drug shows promise in clearing HIV from brain



An experimental drug originally developed to treat cancer may help clear HIV from infected cells in the brain, according to a new study. By targeting infected cells in the brain, drug may clear virus from hidden areas that have been a major challenge in HIV treatment.
Published New Zealand's flightless birds are retreating to moa refuges



Researchers have found New Zealand's endangered flightless birds are seeking refuge in the locations where six species of moa last lived before going extinct.
Published Ancient marine animal had inventive past despite being represented by few species



Brachiopods were evolving in new directions but this did not turn into evolutionary success in terms of the numbers of species, researchers have found.
Published Size doesn't matter for mammals with more complex brains



Mammals that have evolved more developed brains tend to have a smaller size difference between males and females of that species, according to new research.
Published Scientists identify key protein behind spread of shingles virus



Scientists have discovered a new evasion strategy used by the varicella zoster virus, which causes chickenpox and shingles, that may allow it to affect tissues far from the original site of infection.
Published How a bacterium supports healing of chronic diabetic wounds



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.
Published How evolution tamed a deadly virus and why we should still worry



Over the last century, a once-deadly mosquito-borne virus has evolved so that it no longer sickens humans. New research shows that changes in the virus's ability to target human cells paralleled the decline in illness and death. The findings offer important lessons in virology that may help guide better preparedness for future outbreaks of other viral diseases.
Published It's got praying mantis eyes



The praying mantis is one of the few insects with compound eyes and the ability to perceive 3D space. Engineers are replicating their visual systems to make machines see better.
Published New groups of methane-producing organisms in Yellowstone



The team verified that microbes found in Yellowstone National Park hot springs produce methane to grow.
Published Daily rhythms depend on receptor density in biological clock



Tweaking the numbers of receptors in a key brain area changes the daily rhythms of rest and wake in mice.
Published Researchers are closing in on a mouse model for late-onset Alzheimer's



Researchers are working to create the first strain of mice that's genetically susceptible to late-onset Alzheimer's, with potentially transformative implications for dementia research.
