Eu sei que sou um blogger desnaturado e que não mantenho o blog actualizado tanto gostaria ou quanto os leitores/followers/subscritores do RSS merecem.

Aproveito então para avisar que já estão programados vários posts pelo menos para os próximos 10 dias. Tendo tempo até posso programar mais uns quantos. :)

O chamado artigo de caca...

"We calculated that fully grown penguins generate pressures of around 10 kPa (77 mm Hg) to expel watery material and 60 kPa (450 mm Hg) to expel material of higher viscosity similar to that of olive oil. The forces involved, lying well above those known for humans, are high, but do not lead to an energetically wasteful turbulent flow. Whether a bird chooses the direction into which it decides to expel its faeces, and what role the wind plays in this, remain unknown."

The first case of homosexual necrophilia in the
mallard Anas platyrhynchos

"On 5 June 1995 an adult male mallard (Anas platyrhynchos) collided with the glass façade of the Natuurmuseum Rotterdam and died. An other drake mallard raped the corpse almost continuously for 75 minutes. Then the author disturbed the scene and secured the dead duck. Dissection showed that the rape-victim indeed was of the male sex. It is concluded that the mallards were engaged in an ‘Attempted Rape Flight’ that resulted in the first described case of homosexual necrophilia in the mallard"

A parte mais "interessante" é capaz de ser mesmo o ponto The Case, mas não deixa de ser altamente perturbador. Mas francamente o artigo ser publicado 6 anos depois do acontecimento não deixa de ser assustador

Ovulatory cycle effects on tip earnings by lap dancers:
economic evidence for human estrus

"Normally cycling participants earned about US$335 per 5-h shift during estrus, US$260 per shift during the luteal phase, and US$185 per shift during menstruation. By contrast, participants using contraceptive pills showed no estrous earnings peak. These results constitute the first direct economic evidence for the existence and importance of estrus in contemporary human females, in a real-world work setting."

Why the #$%! Do We Swear?

2009-07-12T19:23:00.002+01:00

Bad language could be good for you, a new study shows. For the first time, psychologists have found that swearing may serve an important function in relieving pain.

The study, published today in the journal NeuroReport, measured how long college students could keep their hands immersed in cold water. During the chilly exercise, they could repeat an expletive of their choice or chant a neutral word. When swearing, the 67 student volunteers reported less pain and on average endured about 40 seconds longer.

Although cursing is notoriously decried in the public debate, researchers are now beginning to question the idea that the phenomenon is all bad. "Swearing is such a common response to pain that there has to be an underlying reason why we do it," says psychologist Richard Stephens of Keele University in England, who led the study. And indeed, the findings point to one possible benefit: "I would advise people, if they hurt themselves, to swear," he adds.

How swearing achieves its physical effects is unclear, but the researchers speculate that brain circuitry linked to emotion is involved. Earlier studies have shown that unlike normal language, which relies on the outer few millimeters in the left hemisphere of the brain, expletives hinge on evolutionarily ancient structures buried deep inside the right half.

One such structure is the amygdala, an almond-shaped group of neurons that can trigger a fight-or-flight response in which our heart rate climbs and we become less sensitive to pain. Indeed, the students' heart rates rose when they swore, a fact the researchers say suggests that the amygdala was activated.

That explanation is backed by other experts in the field. Psychologist Steven Pinker of Harvard University, whose book The Stuff of Thought (Viking Adult, 2007) includes a detailed analysis of swearing, compared the situation with what happens in the brain of a cat that somebody accidentally sits on. "I suspect that swearing taps into a defensive reflex in which an animal that is suddenly injured or confined erupts in a furious struggle, accompanied by an angry vocalization, to startle and intimidate an attacker," he says.

But cursing is more than just aggression, explains Timothy Jay, a psychologist at the Massachusetts College of Liberal Arts who has studied our use of profanities for the past 35 years. "It allows us to vent or express anger, joy, surprise, happiness," he remarks. "It's like the horn on your car, you can do a lot of things with that, it's built into you."

In extreme cases, the hotline to the brain's emotional system can make swearing harmful, as when road rage escalates into physical violence. But when the hammer slips, some well-chosen swearwords might help dull the pain.

There is a catch, though: The more we swear, the less emotionally potent the words become, Stephens cautions. And without emotion, all that is left of a swearword is the word itself, unlikely to soothe anyone's pain.

Environome: sequencing the environment

2009-05-06T21:00:00.001+01:00

A pedido do Ska:

Anualmente os novos alunos de doutoramento do Programa Doutoral em Áreas da Biologia Básica e Aplicada organizam o Simpósio Anual do GABBA.

O tema deste ano é Environome: sequencing the environment.

Environome é um novo conceito em ascensão nas diversas áreas da investigação
biomédica. Refere-se aos factores sociais/ambientais/microambientais que interagem num contexto genético, afectando diversos processos biológicos, tais como a saúde de um indivíduo. Esta área científica preocupa-se com um largo espectro de doenças, pois poucas podem ser explicadas exclusivamente pela ocorrência de alterações genéticas.

O simpósio consistirá em comunicações científicas visando recentes descobertas em variadas áreas da biologia que estudam as diferentes interacções entre os genes e o ambiente extracelular. Este simpósio reveste-se de importância na medida em que permite estreitar a relação entre a sociedade e a comunidade científica, visando também cativar o interesse de estudantes para a investigação em novas áreas de pesquisa.

O evento terá lugar no edifício de Biologia da Faculdade de Ciências da Universidade do Porto, no dia 8 de Junho de 2009.
