Quantum phase transition found in a quasi-2D system consisting purely of spins
Publicado em 12 julho 2021
Pure quantum systems can undergo phase transitions analogous to the classical phase transition between the liquid and gaseous states of water. At the quantum level, however, the particle rotates in states that arise from phase transitions, showing collectively entangled behavior. This unexpected observation offers a new way to produce materials with topological properties that are useful in spintronics and quantum computing applications.
The discovery was made by an international collaborator [...]

O vírus zika pode ser uma arma contra o câncer de próstata
Publicado em 01 dezembro 2019Os riscos do vírus zika responsável pela doença silenciosa já são conhecidos, incluindo os numerosos casos de microcefalia em bebês. Agora, o que os pesquisadores da UNICAMP estão examinando é como esse vírus pode ser usado favoravelmente pelo corpo humano, por exemplo, na luta contra tumores. Liderados pelo professor da Universidade Rodrigo Ramos Katarino, os pesquisadores descobriram que esse agente pode ser uma arma contra o [...]ver notícia -
Good for the Heart – Music while Driving a Car – Portal for Naturopathy and Natural Treatment Specialists
Publicado em 14 novembro 2019How can we prevent stress in the car? Stress while driving increases the risk of cardiovascular disease and sudden cardiac complications. If the right music is heard while driving, this risk can be minimized, as a recent study suggests. A recent study by São Paulo State University (UNESP) in Brazil found that listening to music while driving is the right thing to do, which can lead to cardiovascular disease. The results of the study were published in the English-language journal [...]ver notícia -
World’s most powerful electric eel that delivers shock three times stronger than plug socket discovered by s
Publicado em 11 setembro 2019A NEW species of electric eel capable of delivering an electric shock three times that of a domestic wall socket has been found in the Amazon. The eight feet long Electrophorus voltai is the world's most powerful electric eel and is capable of generating 860 volts - enough to stun an adult human. The creatures use electricity to stun their prey and have been known to leap out of the water but deaths of humans are extremely rare. The team that made the discovery also found another species [...]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 last 50 [...]ver notícia -

Air Pollution Affects Tree Growth in São Paulo
Publicado em 20 maio 2019As well as causing significant harm to human health, air pollution also stunts the growth of trees, one of the very elements that can attenuate this typically urban environmental problem. Researchers at the University of Sao Paulo (USP) in Brazil have demonstrated that atmospheric pollutants restrict tree growth and the ecosystem services provided by trees, such as filtering pollution by absorbing airborne metals in their bark, assimilating CO2, reducing the heat island effect by [...]ver notícia
