Cuando pensamos que los rellenos sanitarios de EEUU han sido rebasados, es probable que pensemos en limitar el desperdicio de alimentos, aumentar el reciclaje de plásticos, vidrio y papel y mantener alejados a los residuos peligrosos potencialmente dañinos. Lo que probablemente no consideramos es que una de las mayores fuentes de generación de residuos es la construcción y la demolición (C & D). Se estima que entre un 25 y un 40 por ciento del total nacional de residuos sólidos está relacionado con la construcción, con sólo el 20 por ciento de los residuos que pueden ser reciclados.

The first Britain-wide assessment of the value of wild flowers as food for pollinators shows that decreasing resources mirror the decline of pollinating insects.

Underwater sound linked to human activity could alter the behaviour of seabed creatures that play a vital role in marine ecosystems, according to new research from the University of Southampton.

The study, reported in the journal Scientific Reports published by Nature, found that exposure to sounds that resemble shipping traffic and offshore construction activities results in behavioural responses in certain invertebrate species that live in the marine sediment.

New research published Feb. 2 in the Journal of the American Medical Association found that older adults with a major risk gene for Alzheimer’s disease known as APOEÉ›4 who ate at least one seafood serving per week showed fewer signs of Alzheimer’s-related brain changes.  In contrast, this association was not found in the brains of volunteers who ate fish weekly but did not carry the risk gene.   

New fossils found in Northeastern China have revealed a remarkable evolutionary coincidence: an extinct group of insects known as Kalligrammatid lacewings (Order Neuroptera) share an uncanny resemblance to modern day butterflies (Order Lepidoptera). Even though they vanished some 50 million years before butterflies appeared on earth, they possess the same wing shape and pigment hues, wing spots and eyespots, body scales, long proboscides, and similar feeding styles as butterflies.

A photo of the modern owl butterfly (“Caligo Memnon”) shown beside a fossilized Kalligrammatid lacewing (“Oregramma illecebrosa”) shows some of the convergent features independently evolved by the two distantly-related insects, including wing eyespots and wing scales.

In an incredible example of convergent evolution, both butterflies and kalligrammatids evol
