NewsBlood microbial DNA distinguishes liver cancer from metastatic lesions
A simple blood test analyzing microbial DNA could help doctors tell apart primary liver cancer from colorectal cancer that has spread to the liver, according to a new study.

NewsStudy finds ticks carrying Lyme disease moving into western NC
A new surveillance study reveals that the primary vector of the bacteria that cause Lyme disease, the blacklegged tick, has been spreading into areas previously considered low risk.

NewsIn the wild, chimpanzees likely ingest the equivalent of several alcoholic drinks every day
The first-ever measurements of the ethanol content of fruits available to chimpanzees in their native African habitat show that the animals could easily consume the equivalent of more than two standard alcoholic drinks each day.

NewsResearchers find a more precise way to edit the genome
A genome-editing technique known as prime editing holds potential for treating many diseases. However, the process carries a small chance of inserting errors that could be harmful - but researchers have now found a way to dramatically lower the error rate.

NewsDisease experts upgrade sentinel chicken system to create forecast for West Nile virus
An interdisciplinary team of experts have created a statistical model that accurately predicts the activity of West Nile virus in an area up to six months in advance. The model was trained using two decades of sentinel chicken data.

NewsResearch reveals tropical rainforest soils may fuel climate change as the Earth warms
A new study suggests the Earth’s own tropical soils may contribute to climate change as global warming continues, releasing vast amounts of carbon dioxide (CO₂) as they warm and potentially accelerating a dangerous feedback loop.
-
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.
