  Use it to generate green electricity... Yes, that's what a 23-year-old design student, Daniel Sheridan, did. He created a see-saw that works by transferring the power, created by a child moving up and down on it, to an electricity storage unit via an underground cable. Read more here.

Meu Diario de Bordo presents Rats and Cats Work to Sniff Out Mines posted at Diario de Bordo, saying "Tom and Jerry working together!" GrrlScientist presents Pretty Boys Have All the Chicks posted at Living the Scientific Life, saying, "Everyone is familiar with sexual dichromatism in birds; you know, the gorgeous, colorful male who is paired with the drab female or two. It has been observed in birds that, when males and females differ dramatically in appearance, the females are preferentially mating with a few "pretty boys"; those that have elaborate plumage colors or ornamentation. As a direct result of female breeding preferences, these "pretty boys" sire more offspring than those males with less colorful plumage, thus driving the evolution of sexual dichromatism in the population. This behavior concurrently drives evolution of a polygynous breeding system in the population. But what about those birds that are monogamous yet still show strong sexual dichromatism? How did they get to be that way?" Eric Michael Johnson presents Thirsty for Love, Or: Beetlemania posted at The Primate Diaries.

Oldest child has IQ advantage!Ok, I always knew that, but now I could confirm that. A study conducted in Norway with 250.000 men says that first child has about 2.3 points higher IQ. The reasons could be many, but seems to be a social not a biological situation: "Older siblings might have a higher IQ because they act as surrogate parents from time to time, tutoring their younger siblings in certain situations." "Another possible explanation is that parents have more time and resources to invest in their firstborn child. As a result of this, the eldest child usually has the most one-on-one time with its parents, and receives greater exposure to their sophisticated vocabulary." So, tell me? Are you the first one? Are you smartest?

The word phytotherapy came from the Greek words phyton, plant, and therapeuein, to treat. Or we can just say herbalism, the oldest and fundamental kind of medicine n Earth. For more than 6000 years men has been testing and choosing the best plants to heal their diseases. Since last century, medicine has been using antibiotics and allopathy, and the natural medicine has been forgotten. It's funny how a therapy with just more than 100 years now is called conventional medical therapy, while herbalism is called of alternative medical or non-conventional therapies. Phytoteraphy has the property to cure the whole body, that why is also called holistic health. Plants can heal in a non-aggressive way, stimulating the body self-defences. Plants can help you weight loss, can be an effective stress relief, can help you with occasional sleeplessness, efficiently increase your energy. The easiest way to use plants to heal is teas. But, remember: drink tea without sugar, or with honey, several times a day. Never drink a tea after 24 hours you made it, and don't use the same kind of plant for more than 30 days, because your body will answer less and less. Try to drink a cup of tea instead a cup of coffee, you'll feel much better!
From Nano Expo La Villette WebsiteThere are several interesting things in its website, but this one is really amazing: Programmable nanodermal display
This display would be made up of three billion robot-pixels over a surface of a few square centimetres. The photons emitted by these pixels would produce a picture on the surface of the skin. Activated or deactivated by tapping the hand with a finger, it could be programmed to display information gathered from sensors in or on the human body, such as heartbeat, concentration of oxygen in the blood, glucose level, blood pressure, etc.
 Sim, este Mário mesmo que você pensou! Falando sério, na comunidade da Mensa Brasil no Orkut está rolando uma interessante discussão sobre Criação x Evolução, se Darwin é o capeta, estas coisas. Aliás, sempre temos discussões interessantíssimas por lá: se devemos queimar os astrólogos, quem já recebeu o sinal dos cavaleiros templários, se algum mensan possui telecinese, se Jô Soares é arrogante porque é Mensan, e claro, qual o segredo de Tostines. (sabe como é, estes elevados QI's devem servir pra alguma coisa) E entre todos os participantes, o Mário é o mais sóbrio. Depois de uma acalorada troca de farpas, Mário termina a discussão contando uma fábula: "Certa vez um garoto passeando pela floresta encontrou a Deus e disse: Que bom o Senhor por aqui! Que ótimo pois tenho duas perguntas e um pedido para o Senhor.
Deus disse: - Tudo bem, continue!
- Já que é o criador de tudo o que existe gostaria que me dissesse: como é a Eternidade?
E Deus respondeu:
- a Eternidade para mim, é como se fosse um minuto para você.
O Rapaz prosseguiu:
- Então quanto vale 1 milhão de dólares para o Senhor?
- Um milhão de dólares para você é como 1 centavo para mim, disse Deus.
O rapaz muito “faceiro” abriu um largo sorriso e então pediu:
- Deus, já que um milhão de dólares não é nada mais que um misero 1 centavo para o senhor, me dá esse um centavo?
Deus respondeu:
-Claro que sim meu filho, espere apenas um minuto." Quem tem acesso ao orkut pode ver aqui. Mas, desculpe-me, voce só poderá ler, não poderá participar do fórum uma vez que ele é restrito ao 1% mais inteligente. "Diga-me com quem andas e eu lhe direi seu QI"
