They headed toward the noise, but as they got closer and closer, the sound stopped.
The song belonged to a “miniaturized” animal hidden under the leaves , according to a study published Oct. 25 in the peer-reviewed journal PeerJ.
Researchers collected a dozen of the creatures during field surveys between June 2021 and May 2022 and took a closer look at the unfamiliar amphibians. With a gaping mouth and body smaller than a fingernail, the “toadlet” has now been [...]

Microplastics Found in Brain Affect One Sense in Particular, Study Finds
Publicado em 16 setembro 2024Explains how microplastics in the human brain can affect an important part of our daily lives: how we smell. Researchers in Brazil examined the olfactory bulbs of 15 cadavers and detected the presence of microplastics in the olfactory bulbs of eight of them. The olfactory bulbs, located at the bottom of the brain with one in each nasal cavity, contain different kinds of nerve cells that are responsible for helping us smell. The most common material they found was polypropylene, of [...]ver notícia -

Publicado em 16 setembro 2024Researchers in Germany and Brazil say that 8 out of 15 autopsied adults had microplastics detected within their brain's smell centers, the olfactory bulb. The particles were likely breathed in over a lifetime, since tiny floating microplastics are ubiquitous in the air. Although microplastics have already been found in human lungs, intestines, liver, blood, testicles and even semen, it had long been thought that the body's protective blood-brain barrier might keep the [...]ver notícia
