This week, an interesting story came out in the news about Brazilian scientists working in the United States on an autism study. They discovered an autism “neuron” that they managed to fix in a laboratory experiment. The ground-breaking study, led by Brazilian molecular biologist Alysson Muotri, showed that there may be a possibility to treat or even cure autism. The scientists took skin samples from children with autism and children without autism, and found that the neurons from the children with autism had shorter synapses. They tested a drug to treat the effected neurons, and miraculously, the neurons were fixed. The big challenge now is to find a new treatment that would work outside of a lab.

Cientistas brasileiros consertam ‘neurônio autista’ em laboratório, Portal de Paulinia

“Para analisar diferenças entre os neurônios, a equipe fez uma biópsia de pele de pacientes autistas e de pessoas sem a condição. Depois, reprogramou as células da pele em células de pluripotência induzida (iPS) – idênticas às células-tronco embrionárias, mas não extraídas de embriões. “Pluripotência” é a capacidade de toda célula-tronco de se especializar, ou diferenciar, em qualquer célula do corpo.” READ MORE

Today we’re going to look at an article about lizards and global warming. Have a read and try to answer the questions.

Aquecimento global já leva populações de lagartos à extinção, Estadão

Excerpt: “O aquecimento global está inviabilizando a sobrevivência de várias populações de lagartos, reduzindo o tempo em que os animais  se mantêm ativos para buscar comida e gerar filhotes, diz estudo internacional publicado a revista Science. Pelo menos 5% das espécies existentes já estão comprometidas, afirma o pesquisador brasileiro Carlos Frederico Duarte Rocha, um dos autores do estudo. Rocha é professor do Departamento de Ecologia do Instituto de Biologia da UERJ.

Questions

1. Where does the scientist in the article work? Where did the study take place?

2. Why is global warming contributing to lizard extinction?

3. The scientist studied the Liolaemus lutzae species, found in Rio de Janeiro. How many populations used to exist, and how many have disappeared?

4. What does the Science article predict will happen in 2080?

Last week, scientists and others met at the science and technology fair held by the Sociedade Brasileira para o Progresso da Ciência (Brazilian Society for Scientific Progress) in Manaus, where there was a special exhibit with exotic spiders on display.

The star of the exhibit was a 20 centimeter-long tarantula (below), a member of the theraphosid family, which can grow up to 30 centimeters long. It is not harmful to humans, and feeds on rats, frogs, and other small animals. It can go up to six months without eating, and can live for up to fifteen years.

At the convention, scientists emphasized the need to study spiders–some of which are dangerous to humans–as to be better prepared in case of a bite or an accident.
