In 2009, 1,547 ART children were born in public clinics in Denmark, projecting a net tax revenue of €224 million and €247 million in 25 and 50 years respectively. The authors of the study calculated that reductions of 30-50% in ART cycles following the new policy would lead to cost savings of €67 - €111 million for the Danish government in 2034. By 2059 however, when the IVF cohort are 50 years of age, the government would have lost €74 - €123 million due to less tax contributions from fewer children born.

The question seems simple enough: What happens to the Earth's temperature when atmospheric carbon dioxide levels increase? The answer is elusive. However, clues are hidden in the fossil record. A new study by researchers from Syracuse and Yale universities provides a much clearer picture of the Earth's temperature approximately 50 million years ago when CO2 concentrations were higher than today. The results may shed light on what to expect in the future if CO2 levels keep rising.

raphene, discovered in 2004 at The University of Manchester by Professor Andre Geim and Professor Kostya Novoselov, is one of the world's most versatile materials, and is already being used in such varied applications as touch screens, transistors and aircraft wings.

Researchers from the University are presenting the vast potential of the wonder material at the Royal Society's annual Summer Science Exhibition which opens today (5 July 2010).

Warming of the ocean's subsurface layers will melt underwater portions of the Greenland and Antarctic ice sheets faster than previously thought, according to new University of Arizona-led research. Such melting would increase the sea level more than already projected.

The research, based on 19 state-of-the-art climate models, proposes a new mechanism by which global warming will accelerate the melting of the great ice sheets during this century and the next.

College Park, Md. (July 1, 2011) -- Ever since an ordinary office inkjet printer had its ink cartridges swapped out for a cargo of cells about 10 years ago and sprayed out cell-packed droplets to create living tissue, scientists and engineers have never looked at office equipment in quite the same way. They dream of using a specialized bio-inkjet printer to grow new body parts for organ transplants or tissues for making regenerative medicine repairs to ailing bodies. Both these new therapies begin with a carefully printed mass of embryonic stem cells.

Scientists have shown that soccer players with superior ability in areas such as passing accuracy or sprint speed do not necessarily achieve better overall performance on the pitch.

Gwendolyn David, PhD researcher at the University of Queensland, says "Athletic abilities measured in the lab were not associated with any measure of performance on the pitch. In other words, it's not your ability, it's what you do with it that counts."

In this month's special issue of Physics World, which examines the science and applications of invisibility, Martin McCall and Paul Kinsler of Imperial College London describe a new type of invisibility cloak that does not just hide objects – but events.

Using the ultimate bank heist as an example, McCall and Kinsler explain how a thief could, in principle, use an "event cloak" to steal money from a safe, without even the CCTV surveillance cameras being aware.
