NewsWarming temps alone fail to trigger increased CO2 levels from soil
A study examining the effects of higher temperatures on soil shows that warming alone does not increase levels of carbon dioxide emitted from the soil. Instead, higher temperatures combined with more added carbon led to higher carbon dioxide levels released from the soil.

NewsAI-powered CRISPR could lead to faster gene therapies, study finds
A new AI tool can help scientists better plan gene-editing experiments. CRISPR-GPT acts as a gene-editing “copilot” supported by AI to help researchers — even those unfamiliar with gene editing — generate designs, analyze data and troubleshoot design flaws.

NewsNew CRISPR test could make tuberculosis screening as simple as a mouth swab
Researchers have developed an enhanced CRISPR-based tuberculosis test that works with a simple tongue swab, a potential breakthrough that could allow easier, community-based screenings for the world’s deadliest infectious disease.

NewsBlueberries can improve infants’ immunity and gut health, study finds
Feeding blueberries to infants as one of their first solid foods may help strengthen their immune systems, reduce allergy symptoms and support healthy gut development, according to new research.

NewsScientists can decode wildlife movement to predict the next pandemic
By equipping wildlife with biologging devices that track movement and behavior in near-real-time, researchers can detect early signs of illness, monitor disease spread, and inform public health interventions before outbreaks reach crisis levels.

NewsNew Center of Excellence to respond to the challenge of antibiotic-resistant bacteria
Boston Children’s Hospital and Tulane University have received $25 million in funding from NIAID/NIH to establish a Center of Excellence for Translational Research (CETR) called IMPACT (Immunization against Multidrug-resistant Pathogens: Activating T Cell Immunity).

NewsU.S. Public Health Service releases new guidelines on occupational HIV exposure and postexposure prophylaxis
The CDC, on behalf of the U.S. Public Health Service (PHS), has released the 2025 Guidelines for the Management of Occupational Exposure to Human Immunodeficiency Virus (HIV) and Recommendations for Postexposure Prophylaxis (PEP).

NewsCheese fungi color changes help unlock secrets of evolution
Color changes in fungi on cheese rinds point to specific molecular mechanisms of genetic adaptation—and sometimes a tastier cheese.

NewsSigns of life on Mars? Not so fast, say geologists
Geologists have urged caution in claiming signs of life on Mars from speckled rock found by Perseverance Rover. The researchers believe that a non-biological origin of the speckled rock found on Mars by NASA’s Perseverance rover is just as compelling as a biological one.

NewsResearch identifies immune response that controls Oropouche infection and prevents neurological damage
Research conducted on mice has identified that the rapid response of a specific type of defense cell is essential for controlling Oropouche virus infections and preventing serious neurological damage.

NewsMost Americans favor MMR vaccine requirement for public school, survey finds
Research in April 2025 finds that 70% of the US public supports vaccine requirements for MMR (measles, mumps, and rubella) for children to attend public school, more than in 2023.

NewsResearchers find a way to use antibodies to direct T cells to kill Cytomegalovirus-infected cells
Researchers have found a new way to prompt the immune system to kill cells infected with cytomegalovirus (CMV). They did this by engineering antibodies that direct the immune system’s T-cells to kill cells infected with the virus.

NewsScientists probe how microbial communities and environmental factors impact cotton development
Soil microbial communities play a vital role in plant health, influencing root development, disease resistance, nutrient and soil water uptake and more.Scientists are investigating how these microbial communities impact cotton development and overall yield across diverse climates, agricultural practices and environmental stressors.

NewsAI uncovers hidden rules of some of nature’s toughest protein bonds
Scientists have shown how artificial intelligence can reveal the hidden rules of one of biology’s strangest phenomena: catch-bonds – molecular interactions that get stronger when pulled. Their findings shed light on how bacteria cling to surfaces, how tissues resist tearing, and how new biomaterials might be designed to harness force.

NewsMethod probing dark matter uncovers hundreds of new bacteria, and two potential antibiotics
A new approach to exploring untapped soil resources circumvents the need to grow bacteria in the lab by extracting very large DNA fragments directly from soil to piece together the genomes of previously hidden microbes, and then mines resulting genomes for bioactive molecules.

NewsUS COVID-19 school closures were not cost-effective - but other non-pharmaceutical interventions were
School closures during the COVID-19 pandemic imposed enormous long-term costs while other measures delivered better health outcomes for far less money, according to new research analysing non-pharmaceutical interventions in the United States.

NewsSwitch on, switch off: the dynamic defense of a deadly plant disease
Even strains of Phytophthora infestans considered sensitive to mefenoxam can rapidly develop resistance after a single exposure to a low dose. Researchers have uncovered the dynamics of this defense mechanism, revealing a foe that is more adaptable than previously thought.

NewsResearchers uncover how COVID-19 may linger in cancer patients and affect treatment outcomes
New research is providing important insights into how COVID-19 persists in cancer patients even long after testing positive. Researchers studied three cancer patients who had undergone transplant therapies and were hospitalized with severe COVID-19 infections.

NewsScientists probe tool used by harmful bacteria to hijack crops
Researchers have identified a tool that helps the bacteria Pseudomonas syringae turn a plant’s fundamental biology against itself. The findings could eventually lead to new approaches to protecting crops.
