Two 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 [...]

Call 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 [...]

Researchers 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 [...]

Many of the teenagers across the globe think that skipping breakfast can help them to lose weight. But a study has proved that, in fact, the opposite could be correct. The research that published in the Scientific Reports on Monday stated that missing the first meal of a day is likely to increase the risk of obesity among adolescents. The study tried to find a link between unhealthy eating habits and weight gain. The research also stated that skipping breakfast can contribute to several [...]

In 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 [...]

Remember 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 [...]

Among 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 [...]

Expectant 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 [...]

Brazilian 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 [...]
