a mom's support helps a child learn to handle negative emotions, but what if mom is distressed?

urbana, ill. - handling a poorly timed tantrum from a toddler--such as in the middle of the grocery store--is never an easy task. it could serve as a teachable moment for a mom to help her child learn to manage his own emotions. after all, research shows that how parents react in these types of situations can play an important role in a child's emotional development. but how does that child's negative behavior -- that tantrum in the frozen food aisle -- affect a mother's own stress level, and therefore, her ability to parent?when children become upset, showing negative emotions or behaviors, some parents become distressed themselves, while others are able to talk their child through the difficult situation. studies have shown that a moth...




a walk at the mall or the park? new study shows, for moms and daughters, a walk in the park is best

urbana, ill. - spending time together with family may help strengthen the family bond, but new research from the university of illinois shows that specifically spending time outside in nature--even just a 20-minute walk--together can help family members get along even better. the research is based on the attention restoration theory which describes how interaction with natural environments can reduce mental fatigue and restore attentional functioning. many studies have supported the theory, but most, if not all, previous studies have only looked at the benefits of spending time in nature on an individual's attention. u of i family studies researchers dina izenstark and aaron ebata believed that if this theory worked for individuals it migh...




professor publishes archaeological research on social inequality

missoula - the origins of social inequality might lie in the remnants of ancient eurasia's agricultural societies, according to an article recently published in the major science journal nature.the article, "greater post-neolithic wealth disparities in eurasia than in north america and mesopotamia," includes research from anna prentiss, a professor in the department of anthropology at the university of montana. prentiss and um anthropology professor emeritus tom foor provided data from the archaeological sites at bridge river, british columbia, and ozette, washington. as people became more agricultural and settled, the rich became richer as the ancient farmers who could afford oxen, cattle and other large animals increased their crop prod...




mathematician's study of 'swarmalators' could direct future science

ithaca, n.y. - how does the japanese tree frog figure into the latest work of noted mathematician steven strogatz? as it turns out, quite prominently."we had read about these funny frogs that hop around and croak," said strogatz, the jacob gould schurman professor of applied mathematics. "they form patterns in space and time. usually it's about reproduction. and based on how the other guy or guys are croaking, they don't want to be around another one that's croaking at the same time as they are, because they'll jam each other."strogatz and kevin o'keeffe, ph.d. '17, used the curious mating ritual of male japanese tree frogs as inspiration for their exploration of "swarmalators" - their term for systems in which both synchronization ...




these ring-tailed lemurs raise a 'stink' when they flirt with potential mates

"this behaviour is also very costly because these males are met with higher levels of aggression than if they were to do other types of scent-marking, so there's definitely something unique about this type of behaviour."ring-tailed lemurs are stre...




when to fish: timing matters for fish that migrate to reproduce

image: alaska sockeye salmon migrating. view more credit: dennis wise/university of washingtonit's no secret that human activities affect fish, particularly those that must migrate to reproduce. years of building dams and polluting rivers in some regions have left fish such as salmon struggling to return to their home streams and give birth to the next generation.a new university of washington study points to yet another human factor that is hampering the ability of fish to reproduce: the timing of our fishing seasons. the paper, appearing online last month in the journal fish and fisheries, is one of only a handful of studies that considers how the timing of fishing efforts might disproportionately target certain fish and change the ...

like a baby: the vicious cycle of childhood obesity and snoring

boston - poor nutrition and lack of exercise lead to the increasing prevalence of obesity which, in turn, is the major predictor of diabetes and future risk of cardiovascular disease in western societies. excess weight is also closely associated with obstructive sleep apnea (osa), the increasingly common and potentially serious sleep disorder that is often marked by loud snoring. osa affects about 5 to 10 percent of children 8 to 11 years old. while evidence suggests that osa appears to exacerbate obesity and its comorbidities such as diabetes and cardiovascular disease, its effects on children have not yet been studied in detail.in a new longitudinal observational study, scientists at beth israel deaconess medical center (bidmc) looked at ...

small changes to organ procurement system could lead to more life-saving transplants

slight changes to the system for allocating deceased-donor kidneys could result in higher rates of organ procurement and lead to more kidney transplants across the country, according to new research co-authored by an indiana university kelley school of business professor."any increase in supply will result in saved lives," said rodney p. parker, an associate professor of operations management at kelley. "the lists of patients awaiting a kidney transplantation are lengthy and growing. many of these patients undergo expensive and inconvenient dialysis treatment while waiting."parker and three other researchers studied three risk factors that explain the geographic differences in procuring deceased-donor kidneys across the united states: orga...

hibernating ground squirrels provide clues to new stroke treatments

image: a team of scientists identified a molecule that may reduce stroke-induced brain damage. view more credit: image courtesy of the ninds.in the fight against brain damage caused by stroke, researchers have turned to an unlikely source of inspiration: hibernating ground squirrels. while the animals' brains experience dramatically reduced blood flow during hibernation, just like human patients after a certain type of stroke, the squirrels emerge from their extended naps suffering no ill effects. now, a team of nih-funded scientists has identified a potential drug that could grant the same resilience to the brains of ischemic stroke patients by mimicking the cellular changes that protect the brains of those animals. the study was publ...




age and gut bacteria contribute to ms disease progression, according to rutgers

researchers at rutgers robert wood johnson medical school published a study suggesting that gut bacteria at young age can contribute to multiple sclerosis (ms) disease onset and progression. in this study, published in the october 31 issue of the proceedings of the national academy of sciences, sudhir yadav phd, a neuroimmunology post-doctoral fellow in the laboratories of drs. kouichi ito, associate professor of neurology, and suhayl dhib-jalbut, professor and chair of neurology, tested mice that were engineered to have a pre-disposition for ms. because mice would not normally develop ms, researchers used ms-associated risk genes from real patients to genetically engineer mice for this study. dr. ito created this unique model of genetically...

edna tool detects invasive clams before they become a nuisance

urbana, ill. - when seeking a cure for a disease, early detection is often the key. the same is true for eliminating invasive species. identifying their presence in a lake before they are abundant is vital. a recent university of illinois study successfully used environmental dna to detect invasive clams in california and nevada lakes. researchers believe this tool can help identify pests before they become a problem."environmental dna, or edna, means we're finding the dna of an animal or plant that we're looking for from an environmental sample, like water," says u of i aquatic ecologist eric larson. "it's an emerging tool that has the potential to be better at detecting rare species in some cases, relative to some of our more tradition...

investigating patterns of degeneration in alzheimer's disease

alzheimer's disease (ad) is known to cause memory loss and cognitive decline, but other functions of the brain can remain intact. the reasons cells in some brain regions degenerate while others are protected is largely unknown. in a paper to be published in stem cell reports, researchers from brigham and women's hospital have found that factors encoded in the dna of brain cells contribute to the patterns of degeneration, or vulnerability, in ad. ad is characterized by plaques composed of amyloid β-protein (aβ) and tangles composed of tau protein; accumulation of aβ protein leads to disruption of tau and, eventually, neurodegeneration which affects brain regions in a variety of ways. the front, rostral, portion of the brain is generally m...
