Keeping livestock in the yard just might help your baby’s immune system: Amish babies’ gut microbes lead to more robust immune development in newborn pigs

Getting up close — and a little dirty — with farm animals just might help us fend off illness, say researchers who’ve further demonstrated the benefits of early exposure to a wide variety of environmental bacteria. Scientists from The Ohio State University found that bacteria and other microbes from rural…

New tool for understanding cells in health and disease: A first-of-its-kind data analysis platform is helping make sense of the overwhelming amounts of data generated by single-cell research

A first-of-its-kind data analysis platform is enabling researchers to select the best tool for interpreting the overwhelming amounts of data generated by single-cell research. Accurately making sense of this information will help to explain the vital and varied roles cells play in health and disease. The platform, CellBench, was published…

Scientists unlock new role for nervous system in regeneration: Researchers were able to explain, predict, and even manipulate regeneration of the flatworm body

Biologists at Tufts University have developed a computational model of planarian (flatworm) regeneration that explains how fragments of planaria determine which end should form a tail and which should form a head. The development begins to answer an important question in regeneration research — what are the signals that determine…

New potential approach to treat atopic dermatitis

How does the immune system respond to fungi on our skin? Researchers at the University of Zurich have demonstrated that the same immune cells that protect us against skin fungi also encourage the inflammatory symptoms of atopic dermatitis. An antibody therapy could alleviate this chronic inflammatory skin disease. The skin…

Sewage reveals levels of antimicrobial resistance worldwide

A comprehensive analysis of sewage collected in 74 cities in 60 countries has yielded the first, comparable global data, which show the levels and types of antimicrobial resistant bacteria that are present in mainly healthy people in these countries. The National Food Institute, Technical University of Denmark, headed the study,…

Scientists generate functional, transplantable B cells from mice

Functional B-1 cells derived from mouse embryonic stem cells are capable of long-term engraftment and secrete natural antibodies after transplantation in mice, researchers report February 7th in the journal Stem Cell Reports. Scientists are interested in B-1 cells generated from pluripotent stem cells because they could be tested as a…

Body-painting protects against bloodsucking insects

A study by researchers from Sweden and Hungary shows that white, painted stripes on the body protect skin from insect bites. It is the first time researchers have successfully shown that body-painting has this effect. Among indigenous peoples who wear body-paint, the markings thus provide a certain protection against insect-borne…

Discovery casts doubt on cell surface organization models

Like planets, the body’s cell surfaces look smooth from a distance but hilly closer up. An article published in Communications Biology describes implications, unknown to date, of the way data from cell surfaces are normally interpreted; i.e. as if they lacked topographic features. When Earth is studied from space, its…
