Listening to Music While Driving May Reduce Cardiac Stress
Publicado em 15 novembro 2019
Stress while driving is a risk factor for the development of cardiovascular disease and sudden cardiac complications such as heart attack, but now researchers have found that listening to music while driving can reduce cardiac stress.
"We found that cardiac stress in the participants in our experiment was reduced by listening to music while they were driving," said study lead author Vitor Engracia Valenti, Professor at Sao Paulo State University in Brazil.
For the study, [...]

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 -
A shocking find : new high-voltage electric eels revealed
Publicado em 10 setembro 2019Call it a shock discovery: DNA research has revealed two entirely new species of electric eel in the Amazon basin, including one capable of delivering a record-breaking jolt. The findings are evidence, researchers say, of the incredible diversity in the Amazon rainforest — much of it still unknown to science — and illustrate why it is so important to protect a habitat at risk from deforestation, logging and fires. “In spite of all human impact on the Amazon rainforest in the [...]ver notícia -
CBD Compound In Marijuana Can Reduce Aggressiveness Induced By Isolation
Publicado em 30 julho 2019Researchers of a new study have found that cannabidiol, or CBD, a compound present in marijuana, can reduce aggressiveness brought on by social isolation. Isolation-induced aggressiveness is normally treated with antidepressant or antipsychotic drugs, but earlier studies suggest CBD may also work, so researchers from Brazil conducted an experiment to confirm this. Francisco Silveira Guimarães, from the University of São Paulo's Ribeirão Preto [...]ver notícia -

Oldest Mammal Known From Brazil Named In Tribute To David Bowie
Publicado em 12 junho 2018In December 2015, a broken tooth — a lower premolar, to be precise — was found in fossilized form in the São Paulo state of Brazil, and after two-and-a-half years of analyses, researchers announced it belonged to the oldest known mammal species from the country. They named the species Brasilestes stardusti, as a tribute to musician David Bowie, who died a month after the tooth’s discovery. The fossil is only 3.5 millimeters (just over a tenth of an inch) in size, and the tooth’s roots [...]ver notícia -
Scientists analyse Hiroshima Bombing victims' bone to measure radiation dose
Publicado em 30 abril 2018Remember the two atomic bombs, designed by Los Alamos Laboratory, 'Little Boy' and 'Fat Man', which change the fate of two cities, Hiroshima and Nagasaki in 1945, during Second World War? Scientists from all around the world conducted detail studies on the radiation, which killed thousands of civilians, to understand the effects as well as to gain the insight into it. Even though scientists know that radiation exposure has harmful effects on humans, a Brazilian scientists group has achieved a [...]ver notícia -
Could Jupiter’s Icy Moon Europa Have Life Powered By Nuclear Energy?
Publicado em 24 fevereiro 2018Among the places within our solar system that could potentially support life as we know it (other than Earth, of course), Jupiter’s icy moon Europa is one of the prime candidates. New research by a team of Brazilian researchers indicates native life-forms on the solar system’s sixth-largest moon, if they exist, could be powered by nuclear energy. With its surface covered in a thick layer of ice, thought to be about 10 kilometers (6.2 miles) deep, and a warm subsurface ocean estimated to be [...]ver notícia -
Pregnant women should go for Zika test more than once, says study
Publicado em 02 novembro 2017Expectant women should go for Zika virus test for couple of times as the pathogen can still remain in urine for at least 7 months, said researchers According to the study, the test would exhibit a positive result for Zika virus even though the patients had been initially tested. However, the infectious disease could be clearly detected in patients' urine for up to seven months. "These results suggest the virus continues replicating during pregnancy, in the foetus or the placenta, which must [...]ver notícia -
HIV Vaccine Developed by Brazilian Scientists for Testing Before 2013 Ends to a Colony of Monkeys
Publicado em 06 agosto 2013Brazilian scientists developed an HIV vaccine and planned to test it on monkeys by late 2013. The early stage of the new developed vaccine aimed to maintain the low viral level of an infected person rather than eliminate it. New HIV Vaccine Developed Brazilian scientists who developed an HIV vaccine were planning to test it in monkeys before 2013 ends, according to an institution which sponsored the endeavour. It is known as the HIVBr18 which was developed and patented by a team from the [...]ver notícia
