In addition to helping us chew and swallow, keeping the mouth moist and protecting us against germs, saliva can also be used for early detection of the risk of developing diseases associated with surplus body fat. Researchers at the Federal University of São Paulo (UNIFESP) and the University of Campinas (UNICAMP) in Brazil performed a study in which they used the level of uric acid in saliva to predict body fat percentages in teenagers and identify those with surplus fat even if they [...]

(Fundação de Amparo à Pesquisa do Estado de São Paulo) - Compounds based on palladium, a metal belonging to the same group as platinum, have been developed by researchers from Brazil, the UK and Italy. In vitro tests show action against tumor cells that are resistant to treatment currently used. Original Article: Novel molecules display potent and selective action against ovarian tumor cells

(Fundação de Amparo à Pesquisa do Estado de São Paulo) - Survey of more than 6,000 teenagers performed by Brazilian researchers reinforces protective function of rule-keeping, which relies on open dialogue about the importance of rules as much as on children's monitoring. Findings also show that well-off school students drink most. Original Article: Parental attention can reduce risk of drug abuse in adolescence

Among the cancerous brain tumors, 70 percent are astrocytomas. Fatal in as many as 90 percent of cases, astrocytomas originate in the largest and most numerous cells in the central nervous system, called astrocytes because of their star shape. Original Article: Researchers identify genetic alterations that make a type of brain cancer more aggressive

(Fundação de Amparo à Pesquisa do Estado de São Paulo) - Researchers concluded that medicinal therapy was more than twice as effective as low-intensity brain stimulation, according to a study published in the New England Journal of Medicine. Original Article: Drugs found to be more effective against depression than electric current

A study finds that in and around São José do Rio Preto (São Paulo State, Brazil), where dengue is endemic and there was a rapid outbreak of Zika during the 2016 epidemic, prior dengue infection did not lead to a worse illness for those who got Zika. read more Original Article: Dengue infection does not increase Zika severity

(Fundação de Amparo à Pesquisa do Estado de São Paulo) - A group of researchers at the University of Campinas's Biology Institute (IB-UNICAMP) in São Paulo State, in collaboration with colleagues at the Agronomy Institute (IAC) and at the University of São Paulo's Chemistry Institute (IQ-USP), have discovered how chemical ripeners, which are analogous to plant hormones, act on the molecular level in sugarcane to increase sucrose storage in the plant. Original Article: Study reveals [...]

(Fundação de Amparo à Pesquisa do Estado de São Paulo) - Several species of stingless bees have specialized guards or soldiers to defend their colonies from attacks by natural enemies. The differentiation of these guardian bees evolved in the last 25 million years and coincided with the appearance of parasitic 'robber' bees, which represent a major threat to many stingless bee species. These discoveries were made by a group of researchers in Brazil in collaboration with colleagues in [...]

(Fundação de Amparo à Pesquisa do Estado de São Paulo) - At temperatures close to absolute zero and in the presence of a very intense magnetic field, nickel chloride behaves like a Bose-Einstein condensate, so that the properties of a large group of atoms can be described using a single equation, a single wave function. This discovery makes calculations possible that would otherwise be impracticable. Original Article: Researchers obtain Bose-Einstein condensate with nickel [...]
