Quality of US diet improves, gap widens for quality between rich and poor

Science News Daily - September 1, 2014 - 8:15pm
The quality of the US diet showed some modest improvement in the last decade in large measure because of a reduction in the consumption of unhealthy trans fats, but the gap in overall diet quality widened between the rich and the poor.

Nature's tiny engineers: Corals control their environment, stirring up water eddies to bring nutrients

Science News Daily - September 1, 2014 - 8:14pm
Conventional wisdom has long held that corals -- whose calcium-carbonate skeletons form the foundation of coral reefs -- are passive organisms that rely entirely on ocean currents to deliver dissolved substances, such as nutrients and oxygen. But now scientists have found that they are far from passive, engineering their environment to sweep water into turbulent patterns that greatly enhance their ability to exchange nutrients and dissolved gases with their environment.

Mom's hormones could make female magpie chicks more adventurous

Science News Daily - September 1, 2014 - 11:35am
Female magpies have been shown to be more adventurous than their male siblings, according to new research. “The fact that observable differences between the first hatched and last hatched magpie’s behaviors exist indicates that mothers may be able to produce variable traits, possibly through adjustable transmission of maternal hormones or creating the conditions for sibling rivalry. Mothers could potentially produce a variety of personalities perhaps as an adaptive strategy in unpredictable environmental conditions," researchers say.

Childhood adoption experiences: Effect later in adulthood

Science News Daily - September 1, 2014 - 11:35am
Adoptions have been running at record levels in the UK, with recent figures showing an annual rate of almost 4,000 – up by 15 per cent – while Government reforms have attempted to boost the process. Now a researcher is investigating the long-term impact that adoption makes on individuals.

Scientists call for investigation of mysterious cloud-like collections in cells

Science News Daily - September 1, 2014 - 9:23am
About 50 years ago, electron microscopy revealed the presence of tiny blob-like structures that form inside cells, move around and disappear. But scientists still don't know what they do -- even though these shifting cloud-like collections of proteins are believed to be crucial to the cell, and therefore could offer a new approach to disease treatment. Now, researchers are issuing a call to investigators to focus their attention on the role of these formations.

How neurons in bats' brains ensure a safe flight

Science News Daily - September 1, 2014 - 9:23am
Bats emit ultrasound pulses and measure the echoes reflected from their surroundings. They have an extremely flexible internal navigation system that enables them to do this. A study shows that when a bat flies close to an object, the number of active neurons in the part of a bat's brain responsible for processing acoustic information about spatial positioning increases. This information helps bats to react quickly and avoid obstacles.

Why plants in the office make us more productive

Science News Daily - September 1, 2014 - 8:07am
'Green' offices with plants make staff happier and more productive than 'lean' designs stripped of greenery, new research shows. The team examined the impact of 'lean' and 'green' offices on staff's perceptions of air quality, concentration, and workplace satisfaction, and monitored productivity levels over subsequent months in two large commercial offices in the UK and The Netherlands.

New tuberculosis blood test in children: reliable, highly specific

Science News Daily - September 1, 2014 - 8:07am
A new blood test provides a fast and accurate tool to diagnose tuberculosis in children, a new proof-of-concept study shows. The newly developed test is the first reliable immunodiagnostic assay to detect active tuberculosis in children. The test features excellent specificity, a similar sensitivity as culture tests in combination with speed of a blood test. The promising findings are a major advance for the diagnosis of tuberculosis in children, particularly in tuberculosis-endemic regions.
