The method of serial reproduction has revealed that the social transmission of information is characterized by the gradual transformation of the original message. This transformation results from the preferential survival of certain types of information and the resolution of ambiguity. Here we present evidence of a bias favoring the social transmission of negatively-valenced information across multiple transmission episodes.
Nem sempre a Terra teve flores. Subitamente, elas apareceram – um mistério que Charles Darwin considerou “abominável”. Portugal tem estado a contribuir para o estudo das flores primitivas, graças à descoberta de fósseis de várias plantas novas para a ciência.
Na palma da mão, é um ponto negro, indistinguível a olho nu. Já à lupa binocular, este pedaço de carvão, nem de um milímetro de comprimento, ganha formas. É uma flor, exemplar único, nova para a ciência. Esteve enterrada em argila durante 110 milhões de anos, até ter sido recolhida entre quilos de terra pelo investigador Mário Miguel Mendes perto da vila do Juncal, no concelho de Porto de Mós, distrito de Leiria. Ela e os fósseis de outras três plantas, também classificadas entretanto como novidades científicas, enriquecem as colecções do jardim português do Cretácico, quando os dinossauros reinavam e as plantas com flor começavam a despontar na Terra.

The duration of survival without food is greatly influenced by factors such as body weight, genetic variation, other health considerations and, most importantly, the presence or absence of dehydration.
For total starvation in healthy individuals receiving adequate hydration, reliable data on survival are hard to obtain. At the age of 74 and already slight of build, Mahatma Gandhi, the famous nonviolent campaigner for India's independence, survived 21 days of total starvation while only allowing himself sips of water.
The secrets to staying young may lie in the DNA of the oldest among us.
“There are just two of us left now,” Jemima Westcott says wistfully. Only she and her kid brother, a sprig at age 94, remain of a once-thriving family. Westcott’s older sisters died at age 105 and 107, and she marked her own 105th birthday in January at a dinner party in her cozy condo in Brandon, Manitoba, surrounded by her children and grandchildren.
