A simulation of a pulse of vertically polarized light that's 400 nanometers (nm) and showing 100 nm scale localization when passing (left to right) through a funnel configuration of 30 nm diameter silver nanowires. The purpose of this research, carried out at Argonne National Laboratory, was to learn how to control visible and near-visible light on the nanoscale (nanophotonics) with future generations of optical and electronic devices in mind.

A new way of fixing inactive proteins has been discovered in algae that uses chloroplast extracts and light to release an interrupting sequence from a protein. Many proteins contain extra sequences, called insertions, that can disrupt their function. This research demonstrates that the algae Chlamydomonas reinhardtii has the necessary toolkit to repair proteins by removing these insertions. This repair system may have applications in agriculture and biotechnology because it could potentially be harnessed to enable proteins to become active only in the light.

Ride-hailing companies like Uber have claimed that they've helped discourage drunk driving. Does the claim stand up? David Kirk, co-author of a new study in the American Journal of Epidemiology, tells NPR's Kelly McEvers he's not so sure.

As palm oil production expands from Southeast Asia into tropical regions of the Americas and Africa, vulnerable forests and species on four continents face increased risk of loss, a new study finds. The largest areas of vulnerable forest are in Africa and South America, where more than 30 percent of forests within land suitable for oil palm plantations remain unprotected, the study shows.

A Brigham Young University study found that some walking stick species like this foot-long Phasma gigas, native to Papua New Guinea, re-evolved wings after losing them 50 million years earlier. Walking sticks, a group of insects that mimic twigs to stay hidden from predators, are the only organism known to have re-evolved a complex trait.

The theory of biological evolution in its complete form was presented by a great early zoologist, al-Jahiz in the ninth century.wrote the Turkish theologian Mehmet Bayrakdar in a 1983 issue of the London-based Islamic Quarterly.
creation ... started out from the minerals and progressed, in an ingenious, gradual manner, to plants and animals. The last stage of minerals is connected with the first stage of plants, such as herbs and seedless plants. The last stage of plants, such as palms and vines, is connected with the first stage of animals, such as snails and shellfish ... the last stage of each group is fully prepared to become the first stage of the next group.And 500 years before Khaldun, al-Jahiz articulated a kind of biological selection in his Kitab al-Hayawan (Book of Animals).
In sum, no animal can survive without nourishment. The hunting animal cannot escape being hunted. Every weak animal devours those that are weaker; every strong animal cannot avoid being consumed by those that are stronger.... God, in sum, made some beings the cause of life to others, and in turn made these the cause of death to yet others.
when you see an animal ... of great danger, and concerning whom Man must be very careful, such as snakes and wolves provided with fangs ... thus may you know ... that God--- sublime and powerful is He--- gives to the steadfast, those who understand that free will and rational experience could not exist if the world were purely evil or entirely good.

A sense of drift and apathy has pervaded the global warming and renewable energy debate for too long. The fossil fuel companies continue to dig coal and pump oil and gas; herbivorous idealists, scientists and ecowarriors emit their ritual opposition. The carbon load forced into the atmosphere continues to rise, and the general public seems resigned.
But 2016 is the year this will really begin to change. Chris Goodall's book is wonderfully up to date but, thanks to the pace of change, even he couldn't keep up with the avalanche of news and initiatives conspiring to justify his subtitle. In May, Shell announced a major move into renewables; on 15 May Germany received almost all its electricity from renewables; for four days from 7 to 10 May Portugal did the same. Goodall, who is an economist rather than a technologist or ecowarrior, explains why the change is happening now: the cost of solar electricity is falling much faster than anyone predicted. Solar power is approaching parity with fossil fuels and can only become cheaper as time goes by.
