Can a snake in Thailand influence the evolution of a snake in the Philippines even if the two species never cross paths? According to a new study, the answer may be yes. The research suggests that migratory predators can act as evolutionary “messengers”, carrying their avoidance behavior across continents and linking the fates of species separated by thousands of kilometers. The findings challenge a longstanding assumption in mimicry theory and open the door to a hidden world of long-distance evolutionary relationships connecting distant ecosystems through migration.
Exposure to glyphosate, the active ingredient in many weed killers, was linked to changes in several hormones that support pregnancy and fetal development—in one of the few studies to examine how a widely used herbicide may affect the body during pregnancy. The results come from a new study led by University of Michigan School of Public Health researchers.
A new single-protein analysis technique gives researchers an unprecedented ability to study proteins called scramblases, which have critical roles in biology. The development of the new technique, in a study led by investigators at Weill Cornell Medicine and Ruhr University Bochum in Germany, expands the toolkit available to cell biologists and biophysicists and could someday be useful in devising new strategies against multiple diseases.
A local research study led by scientists from the A*STAR Genome Institute of Singapore (A*STAR GIS) has uncovered how the gut microbiome can influence gene activity in the liver by acting on short stretches of regulatory DNA that function like molecular “switches”. By testing the activity of more than 100,000 human DNA switches linked to liver biology and comparing results from both in vitro and in vivo approaches, the team identified which switches operate under real physiological conditions and how microbial signals can modify their activity. This provides a clearer biological basis for how gut microbes shape liver function, offering new avenues for precision diagnostics and targeted therapies for liver disease. The findings were published in Molecular Cell.
A type of white blood cell in the immune system, known as neutrophils, can make cancer immunotherapy less effective. This is shown in a new study from Karolinska Institutet published in the journal Immunity. The results show that a signalling molecule in the tumour affects neutrophils, reducing the effect of treatment.
Human skeletal biologists traditionally provide sex estimations as a part of establishing biological profiles (skeletal sex, age-at-death, stature, ancestry/population affinity) for skeletonized remains often using the shapes and sizes of the pelvis, long bones and skull, among other bones in the body. While analytical methods portray skeletal sex differences as almost purely binary (female or male), a person’s sex – including hormones, genetics, external anatomy, internal anatomy, and the skeleton – can be more varied than either female or male.
In a new review article, researchers from Boston University Chobanian & Avedisian School of Medicine explore why palpable change in the operationalization of sex and gender has been difficult to fully enact in human skeletal biology with an emphasis on forensic anthropology (the study of skeletonized remains in medico-legal settings). They argue that sex and gender are more complex than a binary determination and that forensic anthropologists are complicit in maintaining faulty notions regarding human variation that may be harmful for marginalized groups.
How do you preserve one of the world’s rarest animals when so few remain? Researchers created an unprecedented 3D digital archive of the vaquita — the world’s most endangered marine mammal. Using advanced CT and micro-CT imaging, the team captured the skeleton of a female porpoise from 1966, in extraordinary detail, from its overall anatomy to microscopic bone structures. Freely available online, the models provide a lasting resource for research, education and conservation, ensuring this critically endangered species on the verge of extinction can be studied for generations to come.
