Scientists discover tiny toad that's world's second-smallest vertebrate
Publicado em 31 outubro 2024
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 São Paulo state.

Breathing Could Bring Microplastics Into the Human Brain, Study Shows
Publicado em 16 setembro 2024MONDAY, Sept. 16, 2024 (HealthDay News) -- 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, [...]ver notícia -
PTSD Triples Odds for Teeth Grinding, Study Finds
Publicado em 16 maio 2024THURSDAY, May 16, 2024 (HealthDay News) -- People 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 [...]ver notícia -
In Brazil, hopes to use AI to save wildlife from roadkill fate
Publicado em 23 abril 2024In Brazil, where about 16 wild animals become roadkill every second, a computer scientist has come up with a futuristic solution to this everyday problem: using AI to alert drivers to their presence. Direct strikes on the vast South American country's extensive road network are the top threat to numerous species, forced to live in ever-closer proximity with humans. According to the Brazilian Center for Road Ecology (CBEE), some 475 million vertebrate animals die on the road every year [...]ver notícia -
Your morning coffee may be more than a half million years old
Publicado em 15 abril 2024That coffee you slurped this morning? It’s 600,000 years old. Using 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 [...]ver notícia -
These are the climate change winners and losers
Publicado emSome plant species will be “winners” while others will be “losers” as global warming forces them to move uphill, suggests a new study. Researchers examined the current range of more than 7,000 plant species in Brazil's Cerrado savanna. They found that the fate of plant species will depend on where they live: lowland species can move uphill for cooler conditions, but mountain plants have nowhere to go. Dr. Mateus Silva, of the University of Exeter said: [...]ver notícia -
Teenage screen time linked to back pain and low achievement
Publicado em 25 abril 2023Teenagers glued to their screens for more than three hours a day suffer worse back pain, a new study has revealed. Girls suffer worse than boys, and back pain is also associated with physical inactivity and low academic achievement. The nearness of the screen to the eyes as well as sitting or lying on your stomach while viewing were also risk factors, along with the duration. The team at São Paulo Research Foundation (FAPESP) in Brazil analyzed data from more than 1,600 school [...]ver notícia -
Too Many 'Bad' Carbs, Too Much Meat: Diet Choices Are Driving Rise in Type 2 Diabetes
Publicado em 18 abril 2023TUESDAY, April 18, 2023 (HealthDay News) -- Most 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 [...]ver notícia -
Even Mild COVID Might Change Your Brain
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 [...]ver notícia -
Vitamin D May Help Maintain Muscle as You Age
