The UK's Millennium Seed Bank, part of the Royal Botanic Gardens, Kew, has collected its billionth seed for safekeeping and conservation. The seed was presented to the British chancellor, Gordon Brown, ahead of an official ceremony at the Seed Bank in southern England late last month to mark World Biodiversity Day. The Millennium Seed Bank (MSB) Project is one of the most ambitious conservation...

The goal of more powerful computers is to enable more demanding applications. I will not venture to take a guess at what will be the dominant "killer applications" for billion transistor chips. Historically new applications have arisen as computers became more powerful; I expect the future to be no different. New applications will continue to demand more and more computing power. The problem of...

A novel fluoranthene based fluorescent chemosensor for the detection of picric acid (PA) at the parts per billion (ppb) level was evaluated. Static fluorescence quenching was the dominant process by intercalative π-π interaction between fluoranthene (S(1)) and nitroaromatics.

The simplest molecules in nature, molecular hydrogen ions in the form of H2(+) and HD(+), provide an important benchmark system for tests of quantum electrodynamics in complex forms of matter. Here, we report on such a test based on a frequency measurement of a vibrational overtone transition in HD(+) by laser spectroscopy. We find that the theoretical and experimental frequencies are equal to ...

This study is an attempt to build a contemporary linguistic corpus for Arabic language. The corpus produced, is a text corpus includes more than five million newspaper articles. It contains over a billion and a half words in total, out of which, there is about three million unique words. The data were collected from newspaper articles in ten major news sources from eight Arabic countries, over ...

the slogan of who in 1986 is “healthy life, victory for all”. it shows more confirmation and attention to positive personal and social activities in direction of health maintenance and health promotion. but in the world that anticipating near one billion people added to young and adolescent population up to 2000 and majority of them live in undeveloped countries and don’t access to health facil...

This editorial is adapted from a previous work by the author, “Seven Billion and 31 Gigatons: Making the Population–Climate Connection,” the author's presentation at Reproductive Health 2011, ARHP's annual clinical conference, and “Policy Review: Thoughts on Addressing Population and Climate Change in a Just and Ethical Manner,” which appeared in Population and Environment in 2009 and is cited ...
