Scientists Find Microplastics Breathed Into Brain
Publicado em 16 setembro 2024
For the first time, scientists have detected microscopic microplastics lodged in the human brain.
Researchers 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 [...]

Study: PTSD Triples Odds for Teeth Grinding
Publicado em 16 maio 2024People with post-traumatic stress disorder (PTSD) face more than triple the odds of bruxism, otherwise known as teeth grinding, a new study finds. The small study of 76 Brazilian adults (38 diagnosed with PTSD and 38 without the condition) found much higher incidence of daytime teeth grinding. “Our study showed that PTSD can be manifested orally, in bruxism and a higher level of pain after a clinical dental examination. This requires joint action by psychiatrists, psychologists and [...]ver notícia -
Your morning coffee may be hundreds of thousands of years old
Publicado em 15 abril 2024Using genes from coffee plants around the world, researchers built a family tree for the world's most popular type of coffee, known to scientists as Coffea arabica and to coffee lovers simply as “arabica.” The researchers, hoping to learn more about the plants to better protect them from pests and climate change, found that the species emerged around 600,000 years ago through natural crossbreeding of two other coffee species. “In other words, prior to any [...]ver notícia -
Poor Food Choices Driving Rise in Type 2 Diabetes
Publicado em 18 abril 2023Most cases of type 2 diabetes can be linked to making poor food choices, a new study finds. Researchers from Tufts University in Boston linked poor diet to 14 million cases of type 2 diabetes — about 70% of new diagnoses globally — in 2018. The biggest impact came from insufficient intake of whole grains, too much refined rice and wheat, and overconsumption of processed meat. "Our study suggests poor carbohydrate quality is a leading driver of diet-attributable type 2 [...]ver notícia -
Even Mild COVID Linked to Brain Changes, Anxiety and Depression
Publicado em 21 fevereiro 2023People who are experiencing anxiety and depression months after a mild case of COVID-19 may have changes affecting the structure and function of their brains, Brazilian researchers report. "There is still much to learn about long COVID, which includes a wide range of health problems, including anxiety and depression, months after infection," said Dr. Clarissa Yasuda of the University of Campinas in São Paulo. "Our findings are concerning, as even people with a mild [...]ver notícia -
Study: Low Vitamin D Increases Aging Muscle Loss by 70 Percent
Publicado em 19 dezembro 2022One way to maintain muscle strength with age: Get enough vitamin D. Researchers in Brazil and the United Kingdom found that older folks who were deficient in the vitamin increased their risk of losing muscle strength by 78%. "Vitamin D is known to participate in various functions. …," said study co-author Tiago da Silva Alexandre, a professor of gerontology at Federal University of São Carlos. "Its many roles include helping to repair muscles and releasing [...]ver notícia -
Saline Spray Could Slow COVID's Spread in the Lungs: Study
Publicado em 24 setembro 2021FRIDAY, Sept. 24, 2021 (HealthDay News) -- A saltwater solution may help stop the SARS-CoV-2 virus in its tracks, Brazilian researchers report. However, although saline may keep the virus from replicating, it does not offer full protection against infection or a cure for COVID-19. "It's not a single solution, and it would have to be used in the first few days after infection," said researcher Cristiane Guzzo, a professor of microbiology at the University of São [...]ver notícia -
A newly identified electric eel species has the strongest shock of any living creature, study says
Publicado em 11 setembro 2019Two new electric eel species have been identified in the Amazon basin, including one fish with a record-breaking shock, scientists say. Researchers had previously identified only one species of electric eel in more than 250 years of studying the creatures that lurk in South American waters and stun their prey with electric discharges. However, the new genetic and ecological analysis, published Tuesday in the peer-reviewed Nature Communications, identifies a total of three unique [...]ver notícia -
'New electric eel species produces strongest animal shock'
Publicado em 11 setembro 2019What was once known as a single species of electric eel is actually three different species, with one of the newly classified organism producing the highest voltage discharge of any known animal, according to a study. The research, published in the journal Nature Communications, offers new insights into the origin and production of strong electric discharges in fishes. Electric eels belong to the knifefish family, and are closely related to catfish and carp than to other eel families, the [...]ver notícia -
Victim's Jawbone Reveals Intensity of Hiroshima Radiation
Publicado em 03 maio 2018A victim's jawbone has revealed the intensity of Hiroshima radiation after the U.S. dropped the first atomic bomb the Japanese city during World War II in 1945, and the result was stunning, according to The Washington Post. The study of the jawbone collected 27 years after the bombing by Brazilian physicist Sérgio Mascarenhas, who was at the time a visiting professor at Harvard University, could not be completed in the 1970s because of technology, the newspaper said. But a new technique [...]ver notícia
