Flood frequency of the world's largest river has increased fivefold

EurekAlert! - Mar, 09/18/2018 - 22:00
A recent study of more than 100 years of river level records from the Amazon shows a significant increase in frequency and severity of floods.

When refugees are barred from working, long-term integration suffers

EurekAlert! - Mar, 09/18/2018 - 22:00
Many European countries prevent asylum seekers from working for a certain waiting period after arrival. These policies can considerably slow their integration years later. Five years after Germany introduced a shorter waiting period in 2000, employment rates were 20 percent lower for refugees who, under the previous policy, had to wait an additional 7 months before entering the labor market. It took this group 10 years to close the gap in employment rates.

DNA tests of illegal ivory link multiple ivory shipments to same dealers

EurekAlert! - Mar, 09/18/2018 - 22:00
In a paper published Sept. 19 in the journal Science Advances, an international team led by scientists at the University of Washington reports that DNA test results of large ivory seizures made by law enforcement have linked multiple ivory shipments over the three-year period, when this trafficking reached its peak, to the same network of dealers operating out of a handful of African ports.

'Robotic Skins' turn everyday objects into robots

EurekAlert! - Mar, 09/18/2018 - 22:00
When you think of robotics, you likely think of something rigid, heavy, and built for a specific purpose. New 'Robotic Skins' technology developed by Yale researchers flips that notion on its head, allowing users to animate the inanimate and turn everyday objects into robots.

Characterization of pregnancy microbiome reveals variations in bacterial diversity

EurekAlert! - Mar, 09/18/2018 - 22:00
In a study published today in Genome Research, researchers performed detailed whole-community sequencing on the microbial communities of three maternal body sites (vagina, gut, and oral cavity) over the course of pregnancy from the first trimester through delivery revealing variations in bacterial diversity.

Journal of the American Medical Association shines spotlight on geroscience

EurekAlert! - Mar, 09/18/2018 - 22:00
Highlighting how geroscience paves the way for therapeutic interventions and extending healthspan at large, three articles co-authored by five AFAR experts will appear in the October 2, 2018 print edition of JAMA and are now available online.

Researchers develop microbubble scrubber to destroy dangerous biofilms

EurekAlert! - Mar, 09/18/2018 - 22:00
Stiff microbial films often coat medical devices, household items and infrastructure such as the inside of water supply pipes, and can lead to dangerous infections. Researchers have developed a system that harnesses the power of bubbles to propel tiny particles through the surfaces of these tough films and deliver an antiseptic deathblow to the microbes living inside.

Viral RNA sensing

EurekAlert! - Mar, 09/18/2018 - 22:00
Even tiny amounts of viruses can have disastrous consequences. RNA identification can reveal the type of virus present. A fast and sensitive technique based on optical detection has now been outlined in the journal Angewandte Chemie. Scientists from Germany and Finland have demonstrated the binding of an RNA target to a probe made of gold nanorods and a DNA origami structure. Chirality switches triggered by binding can be measured by circular dichroism spectroscopy.

Newborn opioid withdrawal requires a 'cascade of care,' study suggests

EurekAlert! - Mar, 09/18/2018 - 22:00
Effective management of neonatal abstinence syndrome (NAS) -- withdrawal symptoms occurring in infants exposed to opioids in utero -- requires a coordinated 'cascade of care' from prevention through long-term follow-up, reports a study in Advances in Neonatal Care, official journal of the National Association of Neonatal Nurses. The journal is published in the Lippincott portfolio by Wolters Kluwer.

Strategies to protect bone health in hematologic stem cell transplant recipients

EurekAlert! - Mar, 09/18/2018 - 22:00
A new review by the International Osteoporosis Foundation Working Group on Cancer and Bone Disease looks at the major factors affecting bone health in mematologic stem cell transplant recipients, and provides expert guidance for the monitoring, evaluation and treatment of bone loss in these patients.

Fiber optic sensor measures tiny magnetic fields

EurekAlert! - Mar, 09/18/2018 - 22:00
Researchers have developed a light-based technique for measuring very weak magnetic fields, such as those produced when neurons fire in the brain.

More doctor visits lead to less suicide attempts for fibromyalgia patients

EurekAlert! - Mar, 09/18/2018 - 22:00
Fibromyalgia patients who regularly visit their physicians are much less likely to attempt suicide than those who do not, according to a new Vanderbilt University Medical Center study published in Arthritis Care & Research.

New insight into aging

EurekAlert! - Mar, 09/18/2018 - 22:00
Researchers at the Montreal Neurological Institute and Hospital (The Neuro) of McGill University examined the effects of aging on neuroplasticity in the primary auditory cortex, the part of the brain that processes auditory information. Neuroplasticity refers to the brain's ability to modify its connections and function in response to environmental demands, an important process in learning.

UT engineers develop first method for controlling nanomotors

EurekAlert! - Mar, 09/18/2018 - 22:00
Engineers at UT Austin develop world's first method for controlling the motion of nanomotors with simple visible light as the stimulus.

Scientists examine variations in a cell's protein factory

EurekAlert! - Mar, 09/18/2018 - 22:00
A group led by Leor S. Weinberger, PhD, director of the Center for Cell Circuitry at the Gladstone Institutes, are studying the factors within a cell that can influence noise. They discovered that for 85 percent of genes, the noise magnitude is higher in the last step as compared to the first step.

Mineral weathering from thawing permafrost can release substantial CO2

EurekAlert! - Mar, 09/18/2018 - 22:00
The amount of carbon dioxide released from thawing permafrost might be greater than previously thought, according to a new study by University of Alberta ecologists. The research is the first to document the potential for substantial contributions of CO2 from thawing permafrost to the atmosphere through an inorganic process called mineral weathering.

Anti-inflammatory protein promotes healthy gut bacteria to curb obesity

EurekAlert! - Mar, 09/18/2018 - 22:00
Scientists from the UNC School of Medicine discovered that the anti-inflammatory protein NLRP12 normally helps protect mice against obesity and insulin resistance when they are fed a high-fat diet. The researchers also reported that the NLRP12 gene is underactive in people who are obese, making it a potential therapeutic target for treating obesity and diabetes, both of which are risk factors for cardiovascular disease and other serious conditions.

'The Peace of Westphalia also had its dark side'

EurekAlert! - Mar, 09/18/2018 - 22:00
The 52nd German Historians' Convention (Deutscher Historikertag) is to reevaluate the peace agreement 370 years ago - "It was only with the Peace of Westphalia that the politics of colonization became possible" - "Its global historical dimensions have long been overlooked" - Two years after Steinmeier's speech, the Historians' Convention will also conduct an interim review of the debate "Peace of Westphalia as a model for the Middle East?"

Going viral: Investors pay more attention to social media stocks

EurekAlert! - Mar, 09/18/2018 - 22:00
What is the value of a social media firm? Paying attention to what investors tune into keeps a finger on the pulse of market fluctuations. And a new study finds that retail investors pay attention to social media stocks over other stocks.
