NewsWhy plastic lingers: Water chemistry slows nature’s cleanup
In a new study designed to mimic real environmental conditions, researchers found that the chemical makeup of natural waters significantly delays the breakdown of polystyrene, a common plastic used in packaging and food containers. Because sunlight cannot effectively initiate the degradation process, microbes cannot finish the job.

NewsBiologist dives beneath Antarctica sea ice to study the impact of climate change
One biologist is studying the genetic diversity of red algae to see how this vital part of Antarctica’s underwater ecosystem is affected by climate change. Answering that question is becoming increasingly important as Earth’s warming climate causes Antarctica’s sea ice to recede farther with every passing year.

NewsStudy finds common infection does not increase risk of recurrent preterm birth
A new study has found that the common sexually transmitted infection, Mycoplasma genitalium, also known as MGen, does not appear to increase the risk of recurrent preterm birth. Earlier research suggested that certain Mycoplasma species might contribute to preterm labor, but those studies were limited.

NewsFirst-in-human clinical trial shows promising results for new Lassa fever vaccine
Researchers have reported encouraging results from an early clinical trial that tested a new dual vaccine against Lassa fever and rabies. The study found that the vaccine was safe and induced immune responses against both viruses. There are currently no vaccines against Lassa fever on the market.

NewsReducing the use of synthetic nitrogen fertiliser via improving nitrogen uptake in corn plants
A new agricultural project will help reduce the use of synthetic nitrogen fertilizer through the design of corn plants that better use nitrogen already in the soil.

NewsPlants could be used to grow medicines in space, study shows
Astronauts on long space missions may one day use plants to produce fresh stocks of medicines on demand. Researchers developed a simple method to grow and repeatedly harvest plant virus-based pharmaceuticals from plants under space-like conditions, without destroying the plants or generating large amounts of waste.

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.

NewsMost cases of HIV persistence in blood following treatment explained by defective copies of the virus
A study based on blood samples strongly suggests that most persistent cases of viral detection, despite ideal HIV drug therapy, are not due to virus transmission or a rebound of active disease.

NewsScientists probe links between green space exposure, mental health and the nasal microbiome
Researchers recently studied associations among green space exposure, mental well-being, and the nasal microbiome—the microbes in a person’s nose. The analysis showed correlations among microbial signatures, time spent outdoors and positive mental well-being.

NewsFood insecurity linked to gut microbiome changes in children
A new study shows that food insecurity may leave a measurable impact on the gut microbiome of children. Children in food-insecure households had different gut microbiome profiles, including higher levels of Sutterella, which has been linked to poor dietary quality and intestinal inflammation.
