Either too much or too little weight gain during pregnancy is associated with adverse outcomes in children aged 7 years

Sep 17 2018 - 00:09
New research published in Diabetologia (the journal of the European Association for the Study of Diabetes [EASD]) shows that if a woman gains either too much or too little weight during pregnancy, there are adverse effects in children at 7 years of age.

E. coli's adaptation to extreme temperatures helps explain resistance to certain drugs

Sep 17 2018 - 00:09
A new study suggests that defenses against extreme temperatures give E. coli bacteria an advantage in fending off certain drugs. The work could help doctors administer antibiotics in a more precise way.

New evidence of a preventative therapy for gout

Sep 17 2018 - 00:09
Solomon and colleagues found a significant reduction in risk of gout attacks among patients who received the drug that targets a key inflammatory molecule, suggesting a new target for therapeutic strategies to prevent gout attacks. Their findings are published online today in Annals of Internal Medicine.

Study reveals the current rates of diagnosed type 1 and type 2 diabetes in American adults

Sep 17 2018 - 00:09
A new study from the University of Iowa finds that type 2 diabetes remains overwhelmingly the most common type of diabetes diagnosed in American adults who have the disease. The study found that among Americans who are diagnosed with diabetes, 91.2 percent have type 2 diabetes and 5.6 percent have type 1 diabetes.

Warnings were up for Hong Kong for Typhoon Mangkhut after landfall

Sep 17 2018 - 00:09
On Sunday, Sept. 16, 2018, Typhoon Mangkhut had made landfall in southern China and Hurricane signal #10 was still in force. NASA's Aqua satellite passed over the storm and captured an image that showed the storm after landfall.

More women than men veterans with chronic pain use therapies like yoga and acupuncture

Sep 17 2018 - 00:09
A major shift in practice by the VA means that therapies such as meditation and yoga are being offered to VA patients as non-drug approaches for pain management, says Elizabeth Evans of UMass Amherst, who studied their use by gender among veterans with chronic musculoskeletal pain.

Turmoil behind primate power struggles often overlooked by researchers

Sep 17 2018 - 00:09
Anyone who peruses relationship settings on social media knows that our interactions with other humans can be intricate, but a new study in Nature: Scientific Reports suggests that researchers may be overlooking some of these same complexities in the social relations of our closest primate relatives, such as chimpanzees and macaques.

Newly discovered enzyme is 'firing pin' for plant immunity

Sep 17 2018 - 00:09
Just like humans, plants have an immune system that helps them fight off infections. Gitta Coaker and colleagues at UC Davis have now identified a key step in how plant cells respond to pathogens -- a family of kinase enzymes that activate the enzymes that make reactive oxygen.

Tropics are widening as predicted by climate models, research finds

Sep 17 2018 - 00:09
Scientists have observed for years that the Earth's tropics are widening in connection with complex changes in climate and weather patterns. But in recent years, it appeared the widening was outpacing what models predicted, suggesting other factors were at work. But a new paper finds that the most up-to-date models and the best data match up reasonably well.

Circuit found for brain's statistical inference about motion

Sep 17 2018 - 00:09
A team of Duke University neuroscientists has found the neural wiring underlying predictive eye-tracking of movements and watched in monkeys as the circuit is set to predict a given speed. They say the neurons of the brain's sensory and motor systems are guided by a combination of past experience and sensory inputs. When replicated in a neural network computer, these educated guesses made by motor neurons mimic Bayesian statistical inference.

NASA data shows Florence brings torrential rains and record flooding to the Carolinas

Sep 17 2018 - 00:09
NASA estimated the precipitation generated by Hurricane Florence from Sept. 10 through 17 as it approached North Carolina and days after it made landfall. On Sept. 17, 2018, Florence's remnant rainfall was moving up the Appalachian Mountains into the Mid-Atlantic.

Thinking beyond yourself can make you more open to healthy lifestyle choices

Sep 17 2018 - 00:09
Many people feel threatened when reminded of their unhealthy behavior. However, a group of 220 sedentary adults became more receptive to health advice -- and more active -- after being primed to either think about their most important values or to make well-wishes for others.

Modeling crystal behavior: Towards answers in self-organization

Sep 17 2018 - 00:09
The University of Tokyo Institute of Industrial Science researchers have created a model to explore the transition behavior of crystal lattices. Their system, based on spheroid particles with a permanent dipole, showed that the combination of anisotropic steric and dipole effects causes frustration that induces the coupling between polarization and strain, resulting in the self-organization. These findings are expected to contribute to the rational design of materials for applications including electro-mechanical actuators and electro-caloric refrigerators.
