New technique for testing nanomaterials Posted: 13 Jul 2016 02:28 PM PDT |
Differences in CEO leadership style, company culture improve firm performance, study finds Posted: 13 Jul 2016 02:23 PM PDT |
Research priorities for National Institutes of Health outlined Posted: 13 Jul 2016 02:23 PM PDT |
Study finds first evidence that PD-1 antibody could help men with metastatic prostate cancer Posted: 13 Jul 2016 02:23 PM PDT A new study is reviving hope that the approach also may help men with life-threatening prostate cancer.It is a surprising turnaround because prior results in men with aggressive, advanced-stage prostate cancer showed no evidence of anti-tumor activity with immune therapies that work by blocking PD-1 signals. |
Which strategies are most effective for reducing use of low-value health services? Posted: 13 Jul 2016 02:23 PM PDT A new study is the first systematic literature review to examine the entire field of interventions designed to reduce low-value care. It also outlines which strategies are potentially the most effective in improving care delivery. Through an analysis of more than 100 articles published in academic journals prior to spring 2015, the study looked at 10 types of low-value care reduction approaches implemented at healthcare settings across the country. |
New study shows differences in blood pressure variation across ethnicity Posted: 13 Jul 2016 12:22 PM PDT |
Students' PTSD symptoms fluctuate greatly during first year of college Posted: 13 Jul 2016 12:22 PM PDT |
Certain characteristics predispose women to different hot flash, night sweat patterns Posted: 13 Jul 2016 12:21 PM PDT Most women will get hot flashes or night sweats at some point in life. However, when these symptoms occur and how long they last can vary dramatically among women. New findings show that women fit into four distinct groups when it comes to getting hot flashes and night sweats, with potential ramifications for therapy and prevention of future health conditions. |

Study links developmental, lipid handling pathways in C. elegans Posted: 13 Jul 2016 12:21 PM PDT |
Calculus I factors women out of STEM degrees Posted: 13 Jul 2016 12:21 PM PDT It's no secret that Calculus I is a major hurdle in the quest for a science degree. But, according to a new paper, the class is far more likely to discourage women than men from continuing on in their chosen field. The findings suggest that a major factor in women's decision to leave a STEM path after Calculus I isn't ability, but confidence in their ability |
Tropical forests overexploited by unsustainable logging Posted: 13 Jul 2016 12:21 PM PDT Widely hailed as a renewable natural resource, tropical timber from old-growth tropical forests is selectively logged worldwide at an unprecedented scale. A new study reveals that once prime tropical hardwoods -- such as Brazilian cedars, ipe (Brazilian walnut), and rosewood -- have been logged, they do not grow back to commercial levels and are at risk from disappearing altogether. |
Mini-brain model of idiopathic autism reveals underlying pathology of neuronal overgrowth Posted: 13 Jul 2016 11:38 AM PDT The majority of cases of autism spectrum disorder (ASD) are unknown. Now researchers have created a "mini-brain" model, derived from persons with a particular form of idiopathic ASD characterized by over-sized brains, revealing a defective molecular pathway during brain development that results in early neuronal overgrowth and dysfunctional cortical networks. |
Using wireless interface, operators control multiple drones by thinking of various tasks Posted: 13 Jul 2016 11:37 AM PDT A researcher has discovered how to control multiple robotic drones using the human brain. A controller wears a skull cap outfitted with 128 electrodes wired to a computer. The device records electrical brain activity. If the controller moves a hand or thinks of something, certain areas light up. A wireless system sends the thought to the robots. |
Shocking new role found for the immune system: Controlling social interaction Posted: 13 Jul 2016 11:31 AM PDT The immune system affects -- and even controls -- social behavior, a new study has found. Researchers discovered that blocking a single type of immune molecule made mouse brains go hyperactive and caused abnormal behavior; restoring it fixed both. The discovery could have enormous implications for neurological conditions such as autism and schizophrenia. |
Indestructible bridges could be reality, thanks to nature-inspired 'form-finding' Posted: 13 Jul 2016 11:31 AM PDT A new generation of indestructible bridges could be possible, thanks to new research. An engineer has taken a design process called 'form-finding', inspired by the natural world, into another level. This could, for the first time, lead to the design of bridges and buildings that can take any combination of permanent loading without generating complex stresses. Such structures will have enhanced safety, and long durability, without the need for repair or restructuring. |

Electricity generated with water, salt and a 3-atoms-thick membrane Posted: 13 Jul 2016 11:30 AM PDT Proponents of clean energy will soon have a new source to add: osmotic power. Or more specifically, energy generated by a natural phenomenon occurring when fresh water comes into contact with seawater through a membrane. Researchers have developed a system that generates electricity from osmosis with unparalleled efficiency. Their work uses seawater, fresh water, and a new type of membrane just 3 atoms thick. |
Earthquake prediction: An innovative technique for monitoring submarine faults Posted: 13 Jul 2016 08:51 AM PDT To monitor a segment of the North Anatolian seismic fault near Istanbul, an international team of researchers has installed a network of transponders on the floor of the Sea of Marmara. The aim is to measure motion of the sea floor on either side of this segment. The data collected during the first six months reveals that the fault is probably locked in the region of this segment, suggesting that there is a progressive build-up of energy that could be released suddenly. This could cause a major earthquake in the Istanbul area. |
Millennials and marrying young: Like mother, like child Posted: 13 Jul 2016 08:49 AM PDT |
Drug-use may hamper moral judgment Posted: 13 Jul 2016 08:49 AM PDT |
Possible to account for disadvantaged populations in Medicare's payment programs Posted: 13 Jul 2016 08:49 AM PDT Medicare's value-based payment programs could take into account social risk factors -- such as low socio-economic position, residence in disadvantaged neighborhoods, or race and ethnicity -- but any proposal to do so will entail both advantages and disadvantages that need to be carefully considered, experts warn. |
Researchers report cybersecurity risks in 3-D printing Posted: 13 Jul 2016 08:49 AM PDT Researchers examined two aspects of additive manufacturing (AM), or 3-D printing, that could have cybersecurity implications and harmful economic impact: printing orientation and insertion of fine defects. They found that because CAD files do not give instructions for printer head orientation, malefactors could deliberately alter the process without detection. Also, sub-millimeter defects that can appear between printed layers with exposure to fatigue and the elements were found to be undetectable by common industrial monitoring techniques. |
Posted: 13 Jul 2016 08:49 AM PDT A recent study examined loss of independence (LOI; defined as a decline in function or mobility, increased care needs at home, or discharge to a nonhome destination) among older patients after surgical procedures and the association of LOI with readmission and death after discharge. Currently, quality metrics prioritized by hospitals and medical professionals focus on discrete outcomes, such as readmission or mortality. |
Stressful trigger events associated with risk of violent crime Posted: 13 Jul 2016 08:49 AM PDT Trigger events, including exposure to violence, were associated with increased risk of violent crime in the week following exposure among patients with schizophrenia and bipolar disorder and among individuals without psychiatric diagnoses who were included for comparison, report investigators at the conclusion of their study. |
Playing action video games boosts visual motor skill underlying driving Posted: 13 Jul 2016 07:58 AM PDT |
New materials for construction of metal-organic 2-dimensional quasicrystals Posted: 13 Jul 2016 07:58 AM PDT Unlike classical crystals, quasicrystals do not comprise periodic units, even though they do have a superordinate structure. The formation of the fascinating mosaics that they produce is barely understood. In the context of an international collaborative effort, researchers have now presented a methodology that allows the production of two-dimensional quasicrystals from metal-organic networks, opening the door to the development of promising new materials. |
Food nudging can help us to eat in a healthier way Posted: 13 Jul 2016 07:58 AM PDT What we eat in the canteen and buy in the supermarket for dinner depends on the order in which the dishes are presented, and how easy it is to get to the products. This is the conclusion of a collaborative review of existing research into food 'nudging.' Until now there's been very little research on this topic, but researchers behind the review expect healthy food nudging to be a predominant subject in the coming years. |
Analysis of ant colonies could improve network algorithms Posted: 13 Jul 2016 07:58 AM PDT An analysis of ant colony behavior could yield better algorithms for network communication, say investigators. Biologists have long suspected that ants base their population-density estimates on the frequency with which they -- literally -- bump into other ants while randomly exploring their environments. That theory gets new support from a theoretical paper. The paper shows that observations from random exploration of the environment converge very quickly on an accurate estimate of population density. Indeed, they converge about as quickly as is theoretically possible. |
Simple procedure could improve treatment for common eye disease Posted: 13 Jul 2016 07:57 AM PDT |

Fat cells may play key role in battle against breast cancer Posted: 13 Jul 2016 07:57 AM PDT New research highlights how fat cells could help determine the most effective way to fight breast cancer, including using exercise to combat the disease. For nearly a half century, researchers have studied the links between obesity and breast cancer. This recent study has revealed specifically that adiponectin and leptin are possible reasons for poorer response to therapy and higher risk of death in obese persons than in others. |

Radical avoidance of plastics in the home: General environmental exposure limits beneficial effects Posted: 13 Jul 2016 07:25 AM PDT The well-known documentary "Plastic Planet" by Werner Boote starkly illustrates the dangers of plastic and synthetics for human beings and also shows how ubiquitous plastic is. Motivated by this multiple award-winning film, a family of five from Styria completely avoided plastics in their home environment for several months. Environmental medicine experts monitored them and analyzed their urine samples at the start of the experiment and again two months in. The main finding of this human biomonitoring study: even if one avoids plastics as far as possible in the home, a certain amount of exposure is inevitable from chemicals and from the environment. |
New analysis recommends responsible prescription of opioids to pain patients Posted: 13 Jul 2016 07:25 AM PDT |
Advancing self-driving car design, other shared human- and machine-controlled systems Posted: 13 Jul 2016 07:16 AM PDT |
Nearly half of California nursing home residents complete end-of-life care orders Posted: 13 Jul 2016 07:16 AM PDT New research finds broad acceptance of written end-of-life care orders among California nursing home residents, with nearly half completing a Physician Orders for Life-Sustaining Treatment, or POLST, form in 2011. The study also found no difference in completion of the form by race or ethnicity, suggesting wide acceptance of these orders among California's highly diverse population. The researchers also identified a few areas where the use of the forms in nursing homes could be improved. |

Today's teenagers could become prematurely hearing-impaired, study warns Posted: 13 Jul 2016 07:16 AM PDT According a recent study, teenagers are increasingly experiencing tinnitus, often a symptom of hearing loss, as a result of using ear buds to listen to music for long periods every day, as well as frequenting very noisy places like nightclubs, discos and rock concerts. The researchers observed that most of the teenagers who took part in the study reported risky listening habits, and those who reported experiencing tinnitus displayed less tolerance of loud sounds. |
New method can identify chemical warfare agents more easily Posted: 13 Jul 2016 07:16 AM PDT |
Ravens learn best from their affiliates Posted: 13 Jul 2016 07:16 AM PDT One of the benefits of living together is gaining new information from group members. Once a group member starts displaying a new behavior, it frequently spreads to the rest of the group. In a study on ravens, cognitive biologists have shown that being socially connected to others is critical in gaining new information. |

Graphene-infused packaging is a million times better at blocking moisture Posted: 13 Jul 2016 07:12 AM PDT Plastic packaging might seem impenetrable -- and sometimes nearly impossible to remove -- but water molecules can still pass through. And this permeability to moisture can limit the lifespan of a product. To better protect goods such as electronics and medicines, scientists have developed a new kind of packaging that incorporates a single layer of graphene. Their material reduces by a million fold how much water can get through. |
Greater privacy, security measures needed to protect patient info in mobile health tech Posted: 13 Jul 2016 07:12 AM PDT With over two-thirds of US adults owning a smartphone, and the rise in miniaturized sensors and low-power body area networks that are used for remote health monitoring, mobile health (mHealth) is beginning to experience a boom. While the technology has the potential to increase healthcare quality, expand access to services, reduce costs, and improve personal wellness and public health, such benefits may not be fully realized unless greater privacy and security measures are implemented, according to a new paper. |
