A new study of marine organisms that make up the 'biofouling community' -- tiny creatures that attach themselves to ships' hulls and rocks in the ocean around the world -- shows how they adapt to changing ocean acidification. Reporting in the journal Global Change Biology, the authors examine how these communities may respond to future change.
Using satellite images to study changing patterns of surface water is a powerful tool for identifying conservationally important 'stepping stone' water bodies that could help aquatic species survive in a drying climate, a UNSW Australia-led study shows. The approach has been applied to the Swan Coastal Plain near Perth in Western Australia, which has more than 1,500 water bodies and is one of 25 designated biodiversity hotspots on the globe.
Ecologists have found the conservation of aquatic ecosystems in Canada has not kept pace with the country's changing landscape, and a prioritization of protection is needed. This new assessment of environmental, human census and business pattern data shows climate warming and northward expansion of human activities over a decade, and can be used to guide strategies for managing freshwater resources by highlighting the regions where humans are now having the greatest impact.
Researchers report that low levels of sodium in the blood, known as hyponatremia, increase the risk of dying for patients on the liver transplant waiting list. The study published in Liver Transplantation, a journal of the American Association for the Study of Liver Diseases and the International Liver Transplantation Society, showed an increase in survival benefit for patients with hyponatremia and a Model for End Stage Liver Disease (MELD) score of 12 or more.
For millions of years, large parts of the marine biotas of the North Atlantic and North Pacific have been separated by harsh climate conditions in the Arctic. A new study published in Nature Climate Change underlines that climate change has begun to weaken this natural barrier promoting the interchange of fishes between the two oceans along with many ecological and economic consequences.
Psychopathic violent offenders have abnormalities in the parts of the brain related to learning from punishment, according to an MRI study led by Sheilagh Hodgins and Nigel Blackwood.
A survey of nearly 1,600 individuals found that the majority were willing to donate tissue samples and medical information to a biobank for research and that most were willing to donate using a blanket consent, according to a study in the Jan. 27 issue of JAMA.
In the first systematic look at the economic outcomes of hospital-based violence intervention, Drexel researchers demonstrate that, in addition to transforming victims' lives, these programs may indeed save a significant amount of money compared to non-intervention, in various sectors including health care and criminal justice, up to about $4 million to serve 90 clients in a 5-year period.
Considerable attention has been paid to how boys' educational achievements in science and math compare to girls' accomplishments in those areas, often leading to the assumption that boys outperform girls in these areas. Now, using international data, researchers at the University of Missouri and the University of Glasgow in Glasgow, Scotland, have determined that girls outperform boys in educational achievement in 70 percent of the countries they studied -- regardless of the level of gender, political, economic or social equality.
As major accounting companies increasingly outsource audit work to other firms, a new study from the University of Colorado Denver Business School says greater transparency is needed to help investors assess the quality of those audits.
