Singing creature — smaller than a fingernail — found in Brazil forest. See new species
Publicado em 28 de outubro de 2024
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 have been found in the human brain. Now what?
Publicado em 13 outubro 2024Microscopic pieces of plastic have been found in waterways, in the air, in our feces, and now, in our brains. A study published last month in the scientific journal JAMA Network Open discovered microplastics in the olfactory bulb of human brains of dead patients. Its the first time these plastics have been found in this region of the brain. We are surrounded by plastics, from our clothes to objects around us to our food packaging, said Thais Mauad, associate professor of pathology at So [...]ver notícia -
Microplastics Found in Brain Affect One Sense in Particular, Study Finds
Publicado em 16 setembro 2024Microplastics continue to be found in some concerning parts of the human body. A new study published Sept. 16 in the JAMA Network Open journal explains how microplastics in the human brain can accumulate in part of the brain that controls 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, [...]ver notícia -
Study: Breathing might bring microplastics into brain
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 -
Growth hormone plays an important role in losing and maintaining weight: Study
Publicado em 13 abril 2019Washington DC: In a recent study, scientists have discovered that growth hormone (GH) plays an important role when it comes to losing and maintaining weight. According to the research published in the journal Nature Communications, GH stimulates skeletal maturation and linear bone growth, as well as helps maintain tissue and organs throughout life, also acts directly on the brain to conserve energy when the body loses weight. "Growth hormone has been known for decades, but our discovery shows [...]ver notícia -
Fungus has decimated the populations of 501 amphibian species worldwide
Publicado emA microscopic aquatic fungus is responsible for the heaviest biodiversity loss ever found to be due to a single pathogen, according to an article published in the journal Science on March 28. The microorganism causes chytridiomycosis, an infectious disease that affects amphibians worldwide. In the past 50 years, it has caused a decline in the populations of at least 501 species of amphibians. In some cases, they have dwindled to less than 10% of their original distribution, and 91 species are [...]ver notícia
