Looks like turtle weed, but it's not
2012-10-10
University of Guam Marine Lab scientist, Tom Shils and coauthor Heroen Verbruggen of the University of Melbourne have recently published an article describing a new species of algae found in the waters of Guam. Rhipilia coppejansii is the fifth green alga described from the Mariana Islands and the first one since 1978. "The molecular tools that aided its identification also reveal that previously undetected biodiversity abounds in the marine algal flora of Guam, which is an integral part of the island's natural heritage in which its people and their culture are deeply rooted," ...
You are feeling sleepy...
2012-10-10
The speed and degree to which the pupil of the eye responds is a standard test for alertness. It has also been used to assess how sleepy or exhausted a person is. Now, research to be published in the International Journal of Bioinformatics Research and Applications suggests that measuring pupil response alone is not enough and that a person's rate of blinking should also be incorporated to obtain a more precise measure of alertness. The work could be important in the care of people with multiple sclerosis and other conditions. It might also be automated and ultimately used ...
HPV vaccination does not lead to an increase in sex
2012-10-10
There have been claims recently that the HPV (Human papillomavirus) vaccination increases sexual activity in adolescent girls as it effectively gives them a 'green light' to have sex because of a perceived protection against sexually transmitted infections. This study published in Vaccine, examines whether or not there is any influence on sexual behaviour as a result of being offered or given the vaccination.
The study looked at a cross-section of over 1,052 girls in the UK, with a mean age of 17.1 years. Of these, 433 had been offered the HPV vaccine and 620 had not ...
CSIC researchers find the exact spot where Julius Caesar was stabbed
2012-10-10
A concrete structure of three meters wide and over two meters high, placed by order of Augustus (adoptive son and successor of Julius Caesar) to condemn the assassination of his father, has given the key to the scientists. This finding confirms that the General was stabbed right at the bottom of the Curia of Pompey while he was presiding, sitting on a chair, over a meeting of the Senate. Currently, the remains of this building are located in the archaeological area of Torre Argentina, right in the historic centre of the Roman capital.

Halving food losses would feed an additional billion people
2012-10-10
More efficient use of the food production chain and a decrease in the amount of food losses will dramatically help maintaining the planet's natural resources and improve people's lives. Researchers in Aalto University, Finland, have proved a valid estimation, for the first time, for how many people could be fed with reducing food losses. The world's population is an estimated seven billion people. An additional one billion can be fed from our current resources, if the food losses could be halved. This can be achieved if the lowest loss percentage achieved in any region ...
Return to Bremerhaven
2012-10-10
Polarstern is expected back from the Central Arctic expedition "IceArc" in Bremerhaven on 8 October 2012 after a good two months. 54 scientists and technicians from twelve different countries conducted research on the retreat of the sea ice and the consequences for the Arctic Ocean and its ecosystems over a period of two months in the High North. A number of new technologies were used for to film and photograph life in and below the ice down to a depth of 4400 metres. Since its departure from Tromsø (Norway) on 2 August 2012 Polarstern has travelled some 12,000 kilometres ...
Sitting on top of the world
2012-10-10
Do you have it in mind to go to a mountain top and study beetles that nobody else has ever seen? Well, there are two fewer such mountains available now that beetle species discovered on Mont Tohiea and Mont Mauru in the Society Islands have been named. James Liebherr, Curator of the Cornell University Insect Collection, has just described 14 species of predatory carabid beetle, also called ground beetles, as part of a U.S. National Science Foundation team that surveyed the insects and spiders of French Polynesia.
Liebherr described the species in two papers published ...
Study: Parenting more important than schools to academic achievement
2012-10-10
New research from North Carolina State University, Brigham Young University and the University of California, Irvine finds that parental involvement is a more significant factor in a child's academic performance than the qualities of the school itself.
"Our study shows that parents need to be aware of how important they are, and invest time in their children – checking homework, attending school events and letting kids know school is important," says Dr. Toby Parcel, a professor of sociology at NC State and co-author of a paper on the work. "That's where the payoff is."
The ...
Are liberal arts colleges disappearing?
2012-10-10
EAST LANSING, Mich. — Liberal arts colleges continue redefining their historical missions or flat-out disappearing – a trend that threatens to diminish America's renowned higher education system, argues a study co-authored by a Michigan State University scholar.
Of the 212 liberal arts colleges identified in a landmark 1990 study, only 130 remain in their traditional form – a 39 percent reduction, according to the new research.
While some liberal arts schools have closed or become part of larger universities due to financial problems, Roger Baldwin, MSU professor of ...
A tactile glove provides subtle guidance to objects in the vicinity
2012-10-10
Researchers at HIIT and Max Planck Institute for Informatics show how computer vision -based hand tracking and vibration feedback on the user's hand can be used to steer the user's hand toward an object of interest. A study shows an almost three-fold advantage in finding objects from complex visual scenes, such as library or supermarket shelves.
Finding an object from a complex real-world scene is a common yet time-consuming and frustrating chore. What makes this task complex is that humans' pattern recognition capability reduces to a serial one-by-one search when the ...

2012-10-10
WASHINGTON, Oct. 9, 2012—By using an ordinary green laser pointer, the kind commonly found in offices and college lecture halls, an Israeli research team has developed a new and highly portable Raman spectrometer that can detect extremely minute traces of hazardous chemicals in real time. The new sensor's compact design makes it an excellent candidate for rapid field deployment to disaster zones and areas with security concerns. The researchers will present their findings at Laser Science XXVIII—the American Physical Society Division of Laser Science's Annual Meeting—collocated ...
Satiation hormone could increase risk of diabetes, heart attack and breast cancer in women
2012-10-10
The findings have been presented in a study from Lund University in Sweden, published in the Journal of the American Medical Association.
"It was surprising to find such a clear link to the risk of type 2 diabetes and cardiovascular disease as well as to breast cancer. Obesity is a common risk factor for all three conditions, but the connection with neurotensin is not explained by obesity or other known risk factors", says Professor Olle Melander from the Department of Clinical Sciences at Lund University, who is also a consultant at Skåne University Hospital.
"This ...

Loss of protective heart failure protein linked to critical limb ischemia
2012-10-10
PHILADELPHIA— Restoring diminished levels of a protein shown to prevent and reverse heart failure damage could also have therapeutic applications for patients with critical limb ischemia (CLI), suggests a new preclinical study published online October 9 in Circulation Research from researchers at the Center for Translational Medicine at Thomas Jefferson University .
Low levels of the protein S100A1 have been linked to congestive heart failure and high blood pressure, and now appear to be associated with critical lower limb ischemia, a condition found in type 2 diabetic ...
Does immune dysfunction contribute to schizophrenia?
2012-10-10
Philadelphia, PA, October 10, 2012 – A new study reinforces the finding that a region of the genome involved in immune system function, called the major histocompatibility complex (MHC), is involved in the genetic susceptibility to schizophrenia.
Schizophrenia is among the most disabling psychiatric disorders. Approximately 80% of the risk for developing schizophrenia is heritable, but there has been slow progress in identifying genetic variation that contributes to the risk for schizophrenia.
The current paper contributes to this growing literature by identifying ...
Living near livestock may increase risk of acquiring MRSA
2012-10-10
People who live near livestock or in livestock farming communities may be at greater risk of acquiring, Methicillin-resistant Staphylococcus aureus (MRSA), according to a new study led by an international team of researchers from the Johns Hopkins Bloomberg School of Public Health, the Dutch Institute for Public Health and the Environment (RIVM) and VU University Medical Center in Amsterdam. A comparison of livestock density, place of residence and existing information on risk factors found that regional density of livestock is an important risk factor for nasal carriage ...
Study shows small fish can play a big role in coastal carbon cycle
2012-10-10
A study in the current issue of Scientific Reports, a new online journal from the Nature Publishing Group, shows that small forage fish like anchovies can play an important role in the "biological pump," the process by which marine life transports carbon dioxide from the atmosphere and surface ocean into the deep sea—where it contributes nothing to current global warming.
The study, by Dr. Grace Saba of Rutgers University and professor Deborah Steinberg of the Virginia Institute of Marine Science, reports on data collected during an oceanographic expedition to the California ...
Applying information theory to linguistics
2012-10-10
CAMBRIDGE, Mass. -- The majority of languages — roughly 85 percent of them — can be sorted into two categories: those, like English, in which the basic sentence form is subject-verb-object ("the girl kicks the ball"), and those, like Japanese, in which the basic sentence form is subject-object-verb ("the girl the ball kicks").
The reason for the difference has remained somewhat mysterious, but researchers from MIT's Department of Brain and Cognitive Sciences now believe that they can account for it using concepts borrowed from information theory, the discipline, invented ...
A problem shared is a problem halved
2012-10-10
The experience of being bullied is particularly detrimental to the psychological health of school girls who don't have social support from either adults or peers, according to a new study by Dr. Martin Guhn and colleagues from the University of British Columbia in Canada. In contrast, social support from adults or peers (or both) appears to lessen the negative consequences of bullying in this group, namely anxiety and depression. The work is published online in Springer's Journal of Happiness Studies.
Guhn and his team looked at whether the combination of high levels ...
Research reveals more about spatial memory problems associated with Alzheimer's
2012-10-10
Researchers at Western University have created a mouse model that reproduces some of the chemical changes in the brain that occur with Alzheimer's, shedding new light on this devastating disease. Marco Prado, Vania Prado and their colleagues at the Schulich School of Medicine & Dentistry's Robarts Research Institute, looked at changes related to a neurotransmitter or chemical messenger, named acetylcholine (ACh), and the kinds of memory problems associated with it. The research is now published online by PNAS.
The researchers, including first author Amanda Martyn, ...
Photonic gels are colorful sensors
2012-10-10
HOUSTON – (Oct. 10, 2012) – Materials scientists at Rice University and the Massachusetts Institute of Technology (MIT) have created very thin color-changing films that may serve as part of inexpensive sensors for food spoilage or security, multiband optical elements in laser-driven systems and even as part of high-contrast displays.
The new work led by Rice materials scientist Ned Thomas combines polymers into a unique, self-assembled metamaterial that, when exposed to ions in a solution or in the environment, changes color depending on the ions' ability to infiltrate ...
Criteria used to diagnose sports head injuries found to be inconsistent
2012-10-10
In recent years it has become clear that athletes who experience repeated impacts to the head may be at risk of potentially serious neurological and psychiatric problems. But a study of sports programs at three major universities, published in the October 2 Journal of Neurosurgery, finds that the way the injury commonly called concussion is usually diagnosed – largely based on athletes' subjective symptoms – varies greatly and may not be the best way to determine who is at risk for future problems. In addition, the way the term concussion is used in sports injuries may ...
