Supermassive black hole clears star-making gas from galaxy's core

Wed, 25/03/2015 - 7:18pm
A new study provides the first observational evidence that a supermassive black hole at the center of a large galaxy can power huge, wide-angled outpourings of material from deep inside the galaxy's core. These outflows remove massive quantities of star-making gas, thus influencing the size, shape and overall fate of the host galaxy.

More big storms increase tropical rainfall totals

Wed, 25/03/2015 - 7:18pm
Increasing rainfall in certain parts of the tropics, colloquially described as the wet get wetter and warm get wetter, has long been a projection of climate change. Now observations have shown that an increase in large thunderstorms is the primary reason for this phenomenon.

Study maps development one U. S. county at a time

Wed, 25/03/2015 - 7:17pm
Researchers have developed a county-by-county map of the United States' "lower 48" that tells a story of land cover and development across the nation, and could provide a framework for planners and policy makers as they consider future development.

Just slip out the back, Jack: Are humans hardwired to break-up and move on?

Wed, 25/03/2015 - 7:17pm
When it comes to romantic relationships, a research review article suggests humans are wired to break-up and move on. Drawing largely upon the field of evolutionary psychology, they say men and women might break up for different reasons. For instance, a man is more likely to end a relationship because a woman has had a sexual relationship with another man. On the other hand, a woman may be more likely to break up if her partner has been emotionally unfaithful.

New form of ice: Square ice filling for a graphene sandwich

Wed, 25/03/2015 - 6:02pm
Water exists in myriad forms, and for poets and scientists alike this structurally simple yet at the same time behaviourally complex molecule never fails to fascinate. In our everyday lives we are familiar with water in its more common liquid, ice and vapour forms. Scientists also study water under more extreme conditions, including at high pressures, where it can exist in the solid state even at room temperature.

Lemur teeth help take a bite out of Madagascar's mysteries

Wed, 25/03/2015 - 5:51pm
Research on lemurs' geographic mobility may help direct future conservation efforts on Madagascar. For centuries, scientists have marveled at Madagascar's lemur species, whose origins are unique to Madagascar. Unfortunately, all large-bodied species of lemur (as well as other native fauna larger in size than a small dog) have gone extinct in the past 2,000 years, most likely due to hunting pressure and deforestation. Researchers believe that gaining a better understanding of how animal mobility has been affected by the loss of species and habitat will be beneficial to current and future conservation efforts on the island.

Shell-shocked: Ocean acidification likely hampers tiny shell builders in Southern Ocean

Wed, 25/03/2015 - 5:51pm
A ubiquitous type of phytoplankton -- tiny organisms that are the base of the marine food web -- appears to be suffering from the effects of ocean acidification caused by climate change. According to authors of a new study, the single-celled organism under study is a type of "calcifying" plankton called a coccolithophore, which makes energy from sunlight and builds microscopic calcium carbonate shells, or plates, to produce a chalky suit of armor.

Hydrolyzed fish fertilizer tested in organic vegetable production

Wed, 25/03/2015 - 5:51pm
A two-year study evaluated an organic fish fertilizer in a squash/collard rotation, and compared its effectiveness to inorganic sources. Although yields were reduced in the crops grown with hydrolyzed fish fertilizer treatments, economic analyses showed that premium prices and potential profits associated with organic products were enough to offset reduced yield. The authors said that the use of hydrolyzed fish fertilizer could be an economically feasible option in organic vegetable production.

Position statement on non-invasive prenatal screening issued

Wed, 25/03/2015 - 5:26pm
Two professional societies of human geneticists have issued a position statement on the promise and challenges of non-invasive prenatal testing, a procedure to test blood drawn from pregnant mothers for Down syndrome and other chromosomal disorders in the fetus. The document addresses the current scope of and future improvements in NIPT technology, ways it may fit with existing prenatal screening protocols, options and priorities in implementation, and associated social and ethical issues.

Experience saves lives: Advanced life-support study reveals differences in survival rates

Wed, 25/03/2015 - 5:25pm
An advanced form of life support that takes over for the failing hearts and lungs of critically ill patients saves lives. But for adults, the odds of surviving depend on which hospital provides the life-supporting treatment -- with the best odds at ones that use the technique dozens of times a year, a new study finds.
