Invading crabs could threaten life in the Antarctic
2014-10-06
(Press-News.org) Life on the Antarctic sea floor is under threat from crabs that could invade the area thanks to favorable conditions as a result of global warming, researchers warn.
In a Journal of Biogeography editorial, experts say invasive species degrade marine ecosystems by preying on or outcompeting local species. Early signs of biological invasion are already apparent.
"Biological invasion is a major worry in the Arctic," said lead author Dr. Richard Aronson, "but we should be just as concerned about the Antarctic." Assessing the extent of the problem requires long-term monitoring programs.

LIVERMORE, California -- Using satellite observations and a large suite of climate models, Lawrence Livermore scientists have found that long-term ocean warming in the upper 700 meters has likely been underestimated.
"This underestimation is a result of poor sampling prior to the last decade and limitations of the analysis methods that conservatively estimated temperature changes in data-sparse regions," said LLNL oceanographer Paul Durack, lead author of a paper appearing in the October 5th issue of the journal Nature Climate Change.
Ocean heat storage is important ...

Among couples with marriage-like commitments, same-sex couples have a similar break-up rate as heterosexual couples, according to a recent study. The study also found that same-sex couples with a marriage-like commitment have stable unions regardless of government recognition.
The findings come from a nationally representative survey of 3,009 couples (471 same-sex) who were followed between 2009 and 2013.
"The marriage commitment is associated with a strong benefit in couple stability for both heterosexual couples and same-sex couples," said Dr. Michael J. Rosenfeld, ...

G-spot, vaginal, or clitoral orgasms are all incorrect terms, experts say. In a recent Clinical Anatomy review, they argue that like 'male orgasm', 'female orgasm' is the correct term.
The authors note that the majority of women worldwide do not have orgasms during intercourse: as a matter of fact, female sexual dysfunctions are popular because they are based on something that does not exist, i.e. the vaginal orgasm.
The key to female orgasm is the female penis—the clitoris, vestibular bulbs and pars intermedia, labia minora, and corpus spongiosum of the female urethra. ...

Familiar voices can improve spoken language processing among school-age children, according to a study by NYU's Steinhardt School of Culture, Education, and Human Development. However, the advantage of hearing a familiar voice only helps children to process and understand words they already know well, not new words that aren't in their vocabularies.
The findings, which were published online in August in the Journal of Child Language, suggest that children store information about a speaker to retrieve and harness at a later time, similar to what has been found for adult ...

In a study of 951 lesbian, gay, and bisexual youth, those experiencing both cyber and school bullying were most likely to engage in aggressive and suicidal behaviors. However, bullied youth who felt connected to an adult at school were not more likely to report such behaviors.
"In recent years, clubs such as Gay-Straight Alliances have played an integral role in creating safer environments in schools. These efforts are often student-led with the guidance of only a handful of adult advisors; however, our study highlights just how important adults are in buffering sexual ...

In a study of 574 low-income adults, many felt stigmatized when receiving medical care. This stigma was most often the result of interactions with clinicians that felt demeaning, rather than an internalized sense of shame related to receiving public insurance or charity care.
Experiencing stigma was associated with unmet health needs, poorer perceptions of quality of care, and worse self-reported health.
"Feeling judged by providers was associated with higher reports of unmet physical and mental health needs and declining health, even though people who reported stigma ...

When the supersonic solar wind hits the Earth's magnetic field, a powerful electrical connection occurs with Earth's field, generating millions of amperes of current that drive the dazzling auroras. These so-called Birkeland currents connect the ionosphere to the magnetosphere and channel solar wind energy to Earth's uppermost atmosphere. Solar storms release torrential blasts of solar wind that cause much stronger currents and can overload power grids and disrupt communications and navigation.
Now for the first time, scientists are making continuous, global measurements ...

Trying on clothes when a shop is closed could become a reality thanks to new research that uses semi-transparent mirrors in interactive systems and which will be unveiled at an international conference tomorrow [Tuesday 7 October].
The research paper, to be presented at one of the world's most important conferences on human-computer interfaces - ACM UIST 2014 [5-8 October], could change the way people interact and collaborate in public spaces, such as museums and shop windows.
The research, led by Professor Sriram Subramanian, Dr Diego Martinez Plasencia and Florent ...

Gender diversity in the workplace helps firms be more productive, according to a new study co-authored by an MIT researcher — but it may also reduce satisfaction among employees.
"Having a more diverse set of employees means you have a more diverse set of skills," says Sara Ellison, an MIT economist, which "could result in an office that functions better."
At the same time, individual employees may prefer less diverse settings. The study, analyzing a large white-collar U.S. firm, examined how much "social capital" offices build up in the form of things like cooperation, ...

The next generation of aircraft could be thinner and lighter thanks to the development of a new imaging technique that could detect damage previously invisible to acoustic imaging systems.
The nonlinear acoustic technique developed by researchers from the University of Bristol's Ultrasonics and Non-destructive Testing (NDT) research group is published in the current issue of Physical Review Letters together with an accompanying article in Physics.
It has long been understood that acoustic nonlinearity is sensitive to many physical properties including material microstructure ...
