Hermit creepy crawlies: Two new taxa of wood-feeding cockroach from China

Hermit creepy crawlies: Two new taxa of wood-feeding cockroach from China
2014-12-19
(Press-News.org) Scientists from the Southwest University, Chongqing, China have found a new species and a new subspecies of cockroach. What makes these creepy crawlies distinctive from the cockroaches most of us know is that they don't infest human houses, on the contrary they prefer to live a hermit life drilling logs, hidden away from human eyes. The study was published in the open access journal ZooKeys.

Out of around 4,600 species worldwide, only 30 are the cockroaches associated with human habitats that gives the bad fame of these creatures. The representatives of the genus Panesthia, to which the new species and subspecies belong, for example are distinctive for drilling logs and xylophagy (feeding on wood), rather than living in houses and eating rubbish.

The new species, P. guizhouensis, was firstly collected from a rotten wood near a large pool where was living undisturbed, and far away from cities in Guizhou Province. A colony of more than 60 nymphs and 52 adults, emerged from the log when the wood was split, quickly fleeing away.

Up to now, 55 species and 9 subspecies have been reported in this genus but because of their secluded lifestyle, these cockroaches are still mysterious to scientists, and their study had been nearly stagnated since 1999. "With this new discovery, we hope to reignite the scientific interest towards this peculiar and rather intriguing cockroach genus." comments Dr Yanli Che, Southwest University, China.

Helping parents understand infant sleep patterns

2014-12-19
Most parents are not surprised by the irregularity of a newborn infant's sleep patterns, but by six months or so many parents wonder if something is wrong with their baby or their sleeping arrangements if the baby is not sleeping through the night. Healthcare providers, specifically nurse practitioners, can help parents understand what "normal" sleep patterns are for their child, according to researchers. "Nurse practitioners are at the frontline of healthcare," said Robin Yaure, senior instructor of human development and family studies, Penn State Mont Alto. "They are ...

High blood sugar in young children with type 1 diabetes linked to changes in brain growth

2014-12-19
Jacksonville, FL (December 19, 2014) - Investigators have found that young children with type 1 diabetes (T1D) have slower brain growth compared to children without diabetes. A new study, published in the December issue of Diabetes, now available ahead of print, suggests that continued exposure to hyperglycemia, or high blood sugars, may be detrimental to the developing brain. The research was supported by the National Institutes of Health (NIH). "Our results show the potential vulnerability of young developing brains to abnormally elevated glucose levels, even when ...

Cells identified that enhance tumor growth and suppress anti-cancer immune attack

2014-12-19
(MEMPHIS, Tenn. - DECEMBER 18, 2014) A study led by St. Jude Children's Research Hospital scientists has identified the population of white blood cells that tumors use to enhance growth and suppress the disease-fighting immune system. The results, which appear in the December 18 edition of the scientific journal Immunity, mark a turning point in cancer immunology and provide the foundation for developing more effective immunotherapies. For years, researchers have known that a diverse group of white blood cells called myeloid-derived suppressor cells (MDSC) are more abundant ...

AGU talk: Scaling climate change communication for behavior change

2014-12-19
In a previous randomized controlled trial, Stanford University researchers developed two curricula for Girl Scouts to use energy more efficiently: one on energy use at home, and the other in transportation and food. Both courses were effective for girls in the short term, and the home energy course was effective for girls in the long term and for parents in the short term. Subsequently, the Northern California Girl Scouts began disseminating the programs via manuals and reusable materials, but that method of disseminating the programs has not lead to widespread use. On ...

Parents' BMI decreases with child involved in school-based, community obesity intervention

Parents BMI decreases with child involved in school-based, community obesity intervention
2014-12-19
[Boston, MA December18, 2014] Parents of children involved in an elementary school-based community intervention to prevent obesity appear to share in its health benefits. A new analysis of Shape Up Somerville: Eat Smart Play Hard™ shows an association between being exposed to the intervention as a parent and a modest decrease in body mass index (BMI) compared to parents in two similar control communities. The study led by researchers at the Friedman School of Nutrition Science and Policy at Tufts University and the Centers for Disease Control and Prevention (CDC) ...

Neuroscientists identify brain mechanisms that predict generosity in children

Neuroscientists identify brain mechanisms that predict generosity in children
2014-12-19
University of Chicago developmental neuroscientists have found specific brain markers that predict generosity in children. Those neural markers appear to be linked to both social and moral evaluation processes. There are many sorts of prosocial behaviors. Although young children are natural helpers, their perspective on sharing resources tends to be selfish. Jean Decety, the Irving B. Harris Professor of Psychology and Psychiatry, and Jason Cowell, a postdoctoral scholar in Decety's Child NeuroSuite lab, wanted to find out how young children's brains evaluate whether ...

Oil palm -- a modeled crop

2014-12-19
Australian scientists have developed a model for oil palm cultivation, aimed at helping growers of the crop maximize the yields of their plantations, while minimizing detrimental environmental impacts. The model was recently published in the journal Environmental Modeling & Software. "Oil palm has become a major crop in the tropics, cultivated on more than 39 million acres of land," co-author Dr Paul Nelson of James Cook University (JCU) said. "Demand for the product continues to grow, and the industry is expected to keep expanding in the foreseeable future. "At ...

A*STAR scientists discover gene critical for proper brain development

2014-12-19
Scientists at A*STAR's Institute of Medical Biology (IMB) and Institute of Molecular and Cellular Biology (IMCB) have identified a genetic pathway that accounts for the extraordinary size of the human brain. The team led by Dr Bruno Reversade from A*STAR in Singapore, together with collaborators from Harvard Medical School, have identified a gene, KATNB1, as an essential component in a genetic pathway responsible for central nervous system development in humans and other animals. By sequencing the genome of individuals of normal height but with a very small head size, ...

Quantum physics just got less complicated

Quantum physics just got less complicated
2014-12-19
Here's a nice surprise: quantum physics is less complicated than we thought. An international team of researchers has proved that two peculiar features of the quantum world previously considered distinct are different manifestations of the same thing. The result is published 19 December in Nature Communications. Patrick Coles, Jedrzej Kaniewski, and Stephanie Wehner made the breakthrough while at the Centre for Quantum Technologies at the National University of Singapore. They found that 'wave-particle duality' is simply the quantum 'uncertainty principle' in disguise, ...

OCD patients' brains light up to reveal how compulsive habits develop

2014-12-19
Misfiring of the brain's control system might underpin compulsions in obsessive-compulsive disorder (OCD), according to researchers at the University of Cambridge, writing in the American Journal of Psychiatry. The research, led by Dr Claire Gillan and Professor Trevor Robbins (Department of Psychology) is the latest in a series of studies from the Cambridge Behavioural and Clinical Neuroscience Institute investigating the possibility that compulsions in OCD are products of an overactive habit-system. This line of work has shifted opinion away from thinking of OCD as ...
