A new study shows that schools and many education programmes are failing to provide students with a basic understanding of evolution.
It is famously difficult to explain evolutionary principles without resorting to anthropomorphic or figurative language. Evolution ‘selects’ the fittest individuals; species ‘adapt’ to change. Both of these phrases are commonplace when explaining the very complex processes involved in evolution. However, this use of language implies that there is an agency o
Light bending reveals clumps of matter around early galaxy.
European astronomers have got their first glimpse of the soup of matter that surrounded a galaxy in the early Universe, just 3 billion years after the Big Bang. Their results provide clues as to how this matter got together, which is crucial to understanding why the Universe looks the way it does today 1 .
The 12-billion-year-old galaxy is called MS 1512-cB58. It is not the earliest galaxy known, but
Weakened polio borrows genes to gain strength for outbreak
Genetic sleuthing has revealed how a dose of oral polio vaccine (OPV) can revert to the deadly poliovirus and cause an outbreak. The research highlights problems that global health organizations face completing their eradication of polio, and the urgency of that effort 1 .
“It reminds us that we need to be very careful in our development of a post-eradication policy,” says Bruce Aylward, leader of the
Successful Test Observations With Powerful New Instrument at Paranal
One of the most fundamental tasks of modern astrophysics is the study of the evolution of the Universe. This is a daunting undertaking that requires extensive observations of large samples of objects in order to produce reasonably detailed maps of the distribution of galaxies in the Universe and to perform statistical analysis.
Much effort is now being put into mapping the relatively nearby space and the
Blue jets connect Earth’s electric circuit.
Video images captured in Puerto Rico suggest that blue flashes of light, much like lightning, feed energy from thunderstorms up into the Earth’s ionosphere – a blanket of electrically charged air some 70 kilometres above the ground 1 .
Some researchers suspect that such phenomena may also fix nitrogen for plants to use and interact with the ozone layer 2 .

+++ EURESCOM for the first time demonstrates seamless access with a PDA. +++
Premiere at the EURESCOM workshop `Wireless Access` in Heidelberg on 12 March: The EURESCOM project on `Bluetooth Access` presented the first PDA, which can seamlessly connect to different access networks, like LAN, Bluetooth, Wireless LAN, and GPRS.
In co-operation with the software company Birdstep from Norway and access point supplier Patria Ailon from Finland, the European project team implement
