NASA and NOAA satellites watch Arlene, first Atlantic Tropical Storm of the season

EurekAlert! - Jue, 04/20/2017 - 22:00
The first tropical storm of the Atlantic Ocean hurricane season formed 40 days before the official kick off of the season. Tropical Storm Arlene formed in the North Central Atlantic Ocean and NOAA's GOES-East satellite provided forecasters with a look at the storm, swirling far from land areas.

Sunflower seeds traced as source of toxic mold, potent liver carcinogen

EurekAlert! - Jue, 04/20/2017 - 22:00
Michigan State University researchers have shown that sunflower seeds are frequently contaminated with a toxin produced by molds and pose an increased health risk in many low-income countries worldwide.

Patients with hyperpigmentation more likely to use sunscreen, few use other sun-protection me

EurekAlert! - Jue, 04/20/2017 - 22:00
Researchers at Boston Medical Center (BMC) and Boston University School of Medicine (BUSM) have found patients with hyperpigmentation, a medical disorder that leads to darkening or increase in the natural color of the skin, are more likely to use sunscreen but do not use other protection measures.

AATS consensus statement helps manage treatment of coronary anomalies

EurekAlert! - Jue, 04/20/2017 - 22:00
Researchers are still trying to fully understand anomalous aortic origin of a coronary artery (AAOCA) and its relationship to adverse health outcomes in humans, especially children. Using the most up-to-date literature, as well as the input of leading experts in the field, the American Association for Thoracic Surgery (AATS) has released practical guidelines for the identification and treatment of AAOCA, including an overview of the latest data surrounding population-based risk.

Northeastern researchers' discovery could aid in detecting nuclear threats

EurekAlert! - Jue, 04/20/2017 - 22:00
Northeastern researchers Yung Joon Jung and Swastik Kar have developed a way to detect nuclear materials that far outpaces any existing method.

New bone-in technique tests therapies for breast cancer metastasis

EurekAlert! - Jue, 04/20/2017 - 22:00
A new laboratory technique developed by researchers at Baylor College of Medicine and other institutions can rapidly test the effectiveness of treatments for life-threatening breast cancer metastases in bone.

Focused issue on vascular disease in women available now

EurekAlert! - Jue, 04/20/2017 - 22:00
Vascular disease is a leading cause of morbidity and death worldwide. There are important sex-related differences in risk factors, clinical manifestations, and therapeutic outcomes in peripheral vascular diseases, including peripheral artery disease (PAD), venous thromboembolism (VTE), and aortic disease. In addition, some vascular conditions predominantly affect women. With this in mind, Vascular Medicine, the official journal of the Society for Vascular Medicine, dedicated its April 2017 issue to the topic of Vascular Disease in Women.

Molecular libraries for organic light-emitting diodes

EurekAlert! - Jue, 04/20/2017 - 22:00
FRANKFURT. Organic light-emitting diodes (OLEDs) are promising candidates for flexible flat displays. By means of a screening process developed by chemists at Goethe University Frankfurt, it is now possible to identify more quickly lead structures with superior luminescence and charge-transport properties.

Probing into the molecular requirements for antioxidant activity

EurekAlert! - Jue, 04/20/2017 - 22:00
Free radicals are derived either from normal essential metabolic processes in the human body or from external sources such as exposure to environmental xenobiotics. A balance between free radicals and antioxidants is essential for proper physiological function.

Antibody delivery mediated by recombinant adeno-associated virus

EurekAlert! - Jue, 04/20/2017 - 22:00
Monoclonal antibody (mAb) based-therapies have revolutionized treatments of cancer and autoimmune diseases because of their specificity and limited toxicity

The protein CHIP unfurls anti-aging activity

EurekAlert! - Jue, 04/20/2017 - 22:00
Not only does our way of life determine how long we live but so too does our genetic material. Of particular importance here is a genetic program that is controlled by the insulin receptor. A team of researchers from the Universities of Cologne and Bonn has now discovered how protein aggregation affects this genetic program and thus triggers aging. The results have now been published in the journal 'Cell'.

Quantum mechanics is complex enough, for now...

EurekAlert! - Jue, 04/20/2017 - 22:00
Physicists have searched for deviations from standard quantum mechanics, testing whether quantum mechanics requires a more complex set of mathematical rules. To do so a research team designed a new photonic experiment using exotic metamaterials, which were fabricated at the University of California Berkeley. Their experiment supports standard quantum mechanics and allows the scientists to place bounds on alternative quantum theories. The results could help to guide theoretical work in a search for a more general version of quantum mechanics.

'Connshing syndrome' named as a new cause of high blood pressure

EurekAlert! - Jue, 04/20/2017 - 22:00
Research led by scientists at the University of Birmingham has revealed a new cause of high blood pressure which could lead to major changes in managing the disease.

Electrochemical performance of lithium-ion capacitors

EurekAlert! - Jue, 04/20/2017 - 22:00
Pre-lithiated multiwalled carbon nanotubes and activated carbon(AC) materials were used as anode and cathode respectively for Lithium-ion capacitors (LICs). The pre-lithiatiation was performed using internal short circuit approach(ISC). The LIC showed excellent supercapacitor performance. The pre-lithiated MWCNTs have a potential application as anode for high performance Lithium-ion capacitors.

How Venus flytrap triggers digestion

EurekAlert! - Jue, 04/20/2017 - 22:00
The Venus flytrap digests its prey using enzymes produced by special glands. For the first time, a research team has measured and meticulously analysed the glands' activity.

Nanoimprinted hyperlens array: Paving the way for practical super-resolution imaging

EurekAlert! - Jue, 04/20/2017 - 22:00
Research conducted by Professor Junsuk Rho's team at POSTECH, South Korea, has demonstrated a scalable and reliable fabrication process of a large scale hyperlens device based on direct pattern transfer techniques. The research team's new cost-effective fabrication method can be used to proliferate practical far-field and real-time super-resolution imaging devices that can be widely used in optics, biology, medical science, nanotechnology, and other related interdisciplinary fields. This achievement has been published in Scientific Reports.

New findings from research into multiple concussions in hockey players

EurekAlert! - Jue, 04/20/2017 - 22:00
The relationship between head injuries suffered during contact sport and Alzheimer's disease is now being called into question thanks to research by the Sahlgrenska Academy, which has revealed that hockey players with multiple concussions probably have other injuries in their brains.
