A study in Brazil involving 89 father-mother-baby triads points to an association between paternal overweight and newborn birth weight: the higher the father's body mass index (BMI, weight divided by height squared), the lower the baby's birth weight. An article on the study is published in the International Journal of Obesity. The findings reinforce the idea that anthropometric issues are not the sole responsibility of the mother and that the father should also strive to maintain [...]

Brazilian scientists have determined that ancient specimens of partially domesticated maize (Zea mays, also known as corn) originally from Peruaçu Valley in Minas Gerais state (Brazil) were the farthest from Mexico, the plant's historic center of origin, of any finds made so far. An article describing their research is published in the journal Science Advances. The study was led by researchers affiliated with the University of São Paulo (USP) and EMBRAPA, the Brazilian [...]

Scientists in Brazil have identified a tiny new frog species in the Atlantic Rainforest, barely visible to the naked eye. Known as Brachycephalus dacnis, this minuscule creature is only 6.95 millimeters in length, fitting comfortably on the tip of a human finger. Researchers describe the frog’s call as cricket-like, making it nearly indistinguishable from insect sounds in its dense forest habitat.

Blue whales are the biggest animals on Earth, but have you wondered which is the smallest? Scientists have recently described one of the world’s tiniest vertebrates: an adorable miniature toad species found in Brazil. They reported their findings in the journal PeerJ. The little guys belong to a subgroup known as flea toadlets or flea toads in the genus Brachycephalus, because they’re able to jump 30 times their body length. The most recently described member of the [...]

By Dean Murray via SWNS The world’s second-smallest vertebrate has been discovered - a tiny toad living in a Brazilian rainforest. Researchers say the flea toad measures just 6.95 millimeters in length and can fit on the tip of a finger. The name of the new species, B. dacnis, pays tribute to Project Dacnis, a conservation, research and education NGO that maintains private areas of the Atlantic Rainforest, including the one where the animal was found, in Ubatuba, on the coast of [...]

Scientists have discovered a strange new toad species smaller than a fingernail in a rainforest in northeast Brazil, shedding more light on the rich diversity of life forms in the region. The species reaches less than 1cm in length as adults and has been named Brachycephalus dacnis after the conservation NGO Project Dacnis behind the discovery. Researchers studying similar small-sized “flea toads” found this species to be particularly interesting due to its diminutive size as [...]

Brachycephalus dacnis, a tiny toad found in Brazil by researchers there, is only 6.95mm long-smaller than some species of ant. "There are small toads with all the characteristics of large toads except for their size. This genus is different. During its evolution, it underwent what we biologists call miniaturization, which involves loss, reduction and/or fusion of bones, as well as fewer digits and absence of other parts of their anatomy," said Luís Felipe Toledo, [...]

Few can resist the appeal of an adorable animal; from diddy chameleons to cute baby cows, the world is full of species that make you go "awww". Now, it seems the ranks of impossibly small and incredible creatures have been bolstered by one new addition: a brand-new species of flea-toad that is the world’s second smallest vertebrate. The new species belongs to the genus Brachycephalus, more commonly known as the flea toads. The other six members of the genus are pretty tiny, [...]
