Highways and roads cost money but it's never a bad idea to save some cost and inconvenience using optimal design and materials which leads to fewer repairs.   Unfortunately there haven't been any great methods for determining how strongly (and safely) roads were built but a scientist in Sweden has developed a method where sound waves can reveal what a road looks like underneath and thereby show whether it is being properly built.

According to the Swedish Road Administration, the method, which is expected to become the new standard, may entail major quality enhancements and cost savings.

There's no shortage of new theories about how kids help to learn better.   Unfortunately when it comes to kids and education, the only way to measure success is after the fact when it may already be too late.

Recent work is focusing on social learning.  It says that infants and young children learn from imitation and by following the actions of those around them, adopting mannerisms and speech patterns.  A new study sought to compare television/computers and audio versus face-to-face human interaction in learning.

Committees and organizations usually start for the right reasons but over time they need to become self-perpetuating.

The International Commission on Stratigraphy (ICS) has managed to milk entire decades out of deciding the boundary dates for the Quaternary Age, which covers both the ice age and moment early man first started to use tools, and it seems they have finally voted on an answer.  

Voting in science?   Indeed, they have formally agreed to move the boundary dates for the prehistoric Quaternary age by 800,000 years, reports the Journal of Quaternary Science. 

A new mathematical model of chronic wound healing could provide better guidance on how to tackle a major public-health problem - the estimated 6.5 million people in the USA who suffer from chronic wounds that can cause loss of limbs or even death.

Ohio State University researchers are the first to publish a mathematical model of an ischemic wound – a chronic wound that heals slowly or is in danger of never healing because it is fed by an inadequate blood supply. Ischemic wounds are a common complication of diabetes, high blood pressure, obesity and other conditions that can be characterized by poor vascular health.

Stéphane Guisard, world-renowned astrophotographer and ESO engineer, has created a  340-million-pixel, 34 by 20-degree wide image from Paranal, the site of the Very Large Telescope, as it looks through an amateur telescope.

Guisard is head of the optical engineering team at Paranal.

To create this true-color mosaic of the Galactic Centre region, Guisard assembled about 1200 individual images, totalling more than 200 hours of exposure time, collected over 29 nights, during Guisard's free time, while working during the day at Paranal. 

Cancer research needs more basic research likely to have the biggest impact on combating the disease in the next few decades but currently research funds are focused on new drug development, says professor Richard Sullivan of the King's Health Partners Integrated Cancer Centre who spoke London told Europe's largest cancer congress, ECCO 15 – ESMO 34 , in Berlin today.

The World Health Organization predicts that the number of people worldwide living with cancer will rise from about 28 million today to about 75 million in 2030.
