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

Air pollution from vehicles is killing tens of thousands of people every year in the UK alone, write Jean Lambert, Molly Scott Cato & Keith Taylor, an outrage set into stark focus by VW's 'test cheating'. The EU's response? To relax tests and allow cars to be more polluting - with the full support of the UK government.

Rather than clamping down on the car industry's irresponsible approach to pollution, EU governments and the Commission instead want to rewrite existing law, providing loopholes which will allow cars to legally pollute more.

Faced with a public health crisis, responsible for nearly half a million premature deaths in Europe each year, we would expect an emergency response.

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.

When we think about the overflow of our nation’s landfills, we probably picture limiting our food waste; recycling plastics, glass and paper; and keeping out potentially harmful hazardous waste. What we probably don’t consider is one of the largest sources of waste generation, construction and demolition (C&D) waste.  It is estimated that anywhere from 25 to 40 percent of the national solid waste stream is building-related waste, with only 20 percent of C&D waste being recycled.

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.
