Brookhaven Lab researchers develop a technique to measure defects in materials with unprecedented accuracy

Researchers at Brookhaven National Laboratory have developed a technique to measure defects in materials with picometer accuracy, enabling the design of advanced materials. The new technique uses interferometry in coherent electron diffraction and is particularly suited for investigating tiny areas of materials.

Economic penalty of extra pounds

Researchers analyzed data from over 7,000 men and women in their 50s and 60s and found that obesity was associated with significantly lower net worth for middle-aged women. The economic cost of obesity on women's wealth is substantial, ranging from $135,670 in 1998 for moderately to severely obese women compared to non-obese peers.

Bilbies invade central Australia

The Arid Zone Recovery Project successfully re-introduced Greater Bilbies to a 14 square kilometre exclosure, with estimates suggesting around 20 bilbies now living in the site. The project also reintroduced other species, such as Burrowing Bettongs and birds like the Bush Thick-knee and Plains Wanderer.
