Tropical Storm Simon is following the path of several other tropical storms that formed in the Eastern Pacific Ocean by crawling northward along the western coastline of Mexico. NOAA's GOES-West satellite captured an infrared image of Simon on Oct. 3 that showed the eastern side of the storm over Mexico. An infrared image taken from NOAA's GOES-West satellite on Oct .3 at 7:45 a.m. EDT showed strong thunderstorms circling Tropical Storm Simon's center and a fragmented band of thunderstorms in Simon's eastern quadrant bringing rainfall to western Mexico. Simon's center ...

Scientists at the U.S. Department of Energy's Argonne National Laboratory have created a new model to more accurately describe the greenhouse gases likely to be released from Arctic peatlands as they warm. Their findings, based on modeling how oxygen filters through soil, suggest that previous models probably underestimated methane emissions and overrepresented carbon dioxide emissions from these regions. Peatlands, common in the Arctic, are wetlands filled with dead and decaying organic matter. They are the result of millions of years of plants dying and breaking down ...

It has become common for people who have pets to refer to themselves as "pet parents," but how closely does the relationship between people and their non-human companions mirror the parent-child relationship? A small study from a group of Massachusetts General Hospital (MGH) researchers makes a contribution to answering this complex question by investigating differences in how important brain structures are activated when women view images of their children and of their own dogs. Their report is being published in the open-access journal PLOS ONE. "Pets hold a special ...

West Orange, NJ. October 3, 2014. Stroke researchers have confirmed that damage to the right frontal-subcortical network may cause ipsilateral spatial neglect. Among individuals with ipsilateral neglect, a much greater proportion had frontal subcortical damage than anticipated by the investigators – 83% vs the expected 27%. A difference was also seen in spatial bias, ie, the type of spatial errors among this group tended to be 'where' (perceptual-attentional) rather than 'aiming' (motor-intentional) errors. Ipsilesional Neglect: Behavioral and Anatomical Correlates (doi: ...

A powerful scientific tool for editing the DNA instructions in a genome can now also be applied to RNA, the molecule that translates DNA's genetic instructions into the production of proteins. A team of researchers with Berkeley Lab and the University of California (UC) Berkeley has demonstrated a means by which the CRISPR/Cas9 protein complex can be programmed to recognize and cleave RNA at sequence-specific target sites. This finding has the potential to transform the study of RNA function by paving the way for direct RNA transcript detection, analysis and manipulation. A ...

In the latest issue of the IEEE Journal of Microelectromechanical Systems, Velásquez-García, his graduate students Eric ...

Cincinnati, OH, October 3, 2014 -- Increasing rates of adolescent obesity and the likelihood that obesity will carry forward into adulthood, have led to various preventive initiatives. It has been suggested that family meals, which tend to include fruits, vegetables, calcium, and whole grains, could be protective against obesity. In a new study scheduled for publication in the Journal of Pediatrics, researchers studied whether frequent family meals during adolescence were protective for overweight and obesity in adulthood. Jerica M. Berge, PhD, MPH, LMFT, CFLE, and ...

In the field of medicine there has often been a divide between those who focus on modern medicine and those who prefer alternative practices. But pediatrician Sunita Vohra is a firm believer there should be room for both. A new study from Vohra, a professor in the Faculty of Medicine & Dentistry's Department of Pediatrics at the University of Alberta, and a pediatric physician for Clinical Pharmacology with Alberta Health Services, is giving insight into the use of alternative medicines by pediatric cardiac patients and how effective they are seen to be. "We wanted to ...

Tel Aviv — The incidence of type 1 childhood diabetes has been increasing rapidly worldwide. If blood sugar levels aren't well-controlled, juvenile diabetes can affect nearly every organ of a child's body. And while long-term complications of the disease develop gradually, they may become disabling and even life-threatening. The exact cause of juvenile diabetes has eluded scientists, but a new study from Tel Aviv University suggests a likely trigger before birth. In a recent paper published in Diabetic Medicine, Prof. Zvi Laron, Professor Emeritus of Pediatric Endocrinology ...

Led by a Massachusetts General Hospital (MGH) physician, the report in the October issue of the Journal of Allergy and Clinical Immunology supports the results of a preliminary study that showed similar results in a small group of children in Boston. "While we don't know the exact proportion of patients with atopic dermatitis whose symptoms worsen in the winter, the ...

As global life expectancy increases, adults want to maintain healthy and active lifestyles well into retirement. In fact, research shows that adults think, feel and behave five to ten years younger than their actual age.1-2 But new findings from a review paper published in Age and Ageing show that approximately one out of three adults age 50 and older suffer from sarcopenia, a condition that could interfere with aging adults' ability to live a full and active life.3 Sarcopenia, as it is known in the medical field, is a condition when a person has progressive loss of ...

CAMBRIDGE, Mass--When someone crumples a sheet of paper, that usually means it's about to be thrown away. But researchers have now found that crumpling a piece of graphene "paper" — a material formed by bonding together layers of the two-dimensional form of carbon — can actually yield new properties that could be useful for creating extremely stretchable supercapacitors to store energy for flexible electronic devices. The finding is reported in the journal Scientific Reports by MIT's Xuanhe Zhao, an assistant professor of mechanical engineering and civil and environmental ...

TORONTO, October 3, 2014 – Ache, agony, distress and pain draw more attention than non-pain related words when it comes to people who suffer from chronic pain, a York University research using state-of-the-art eye-tracking technology has found. "People suffering from chronic pain pay more frequent and longer attention to pain-related words than individuals who are pain-free," says Samantha Fashler, a PhD candidate in the Faculty of Health and the lead author of the study. "Our eye movements — the things we look at — generally reflect what we attend to, and knowing how ...

Previously undiscovered secrets of how human cells interact with a bacterium which causes a serious human disease have been revealed in new research by microbiologists at The University of Nottingham. The scientists at the University's Centre for Biomolecular Sciences have shed new light on how two proteins found on many human cells are targeted by the human pathogen Neisseria meningitidis which can cause life-threatening meningitis and septicaemia. The proteins, laminin receptor (LAMR1) and galectin-3 (Gal-3) are found in and on the surface of many human cells. Previous ...

The world's fiber-optic network spans more than 550,000 miles of undersea cable that transmits e-mail, websites, and other packets of data between continents, all at the speed of light. A rip or tangle in any part of this network can significantly slow telecommunications around the world. Now engineers at MIT, along with computer scientists at Columbia University, have developed a method that predicts the pattern of coils and tangles that a cable may form when deployed onto a rigid surface. The research combined laboratory experiments with custom-designed cables, computer-graphics ...

Although these highly aligned polymer films (HAPFs) are in demand, previous fabrication ...

When you take a shower and rinse the soap and shampoo off your body, the foam conveniently disappears between your toes and down the drain. Have you ever thought about what happens to the surfactants afterwards? Whether they seep into the groundwater, lakes and streams, where they could pose a risk to fish and frogs? Not likely. This is shown in a new and very comprehensive report of the potential impact on the environment of the enormous amounts of common surfactants used day in and day out by consumers all over the world. "We humans use several million tons of ...

Microfluidic tools for precision measurements of cell migration speed reveal that migratory speed of individual cells changes stochastically from parent cells to their descendants, while the average speed of the cell population remains constant through successive generations. A team of researchers at the Massachusetts General Hospital and Harvard Medical School in Boston has developed technologies for precision measurement of cell migration speed before and applied the new tool to study the variations of migration speed in population of cancer cells. This tool enabled ...

Scientists at the University of Granada, in collaboration with La Paz University Hospital in Madrid and the University of Texas, San Antonio in the US have demonstrated through several experiments conducted on Zucker obese rats that chronic consumption of melatonine helps combat obesity and diabetes mellitus type two. Their research has confirmed that chronic administration of melatonine in young obese rats with diabetes mellitus type two, similar to its human equivalent, improves mitochondrial dysfunction (i.e. mitochondrial homeostatic functions) in a very efficient ...
