Before Charlotte the spider spelled the word "humble" in her web to describe Wilbur the pig, she told Templeton the rat that the word meant "not proud." That's probably what most people say if you put them on the spot. But if you give them time to think about it deeply, like a new study just did, other themes emerge that have a lot to do with learning. And these intellectual dimensions of humility describe the spider as well or better than the pig. "Wilbur has many of the dimensions of humility in general: regard for others, not thinking too highly of himself - but ...

The sun emitted a mid-level flare on Dec. 18, 2014, at 4:58 p.m. EST. NASA's Solar Dynamics Observatory, which watches the sun constantly, captured an image of the event. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where GPS and communications signals travel. To see how this event may affect Earth, please visit NOAA's Space Weather Prediction Center at http://spaceweather.gov, ...

New UCLA research indicates that lost memories can be restored. The findings offer some hope for patients in the early stages of Alzheimer's disease. For decades, most neuroscientists have believed that memories are stored at the synapses -- the connections between brain cells, or neurons -- which are destroyed by Alzheimer's disease. The new study provides evidence contradicting the idea that long-term memory is stored at synapses. "Long-term memory is not stored at the synapse," said David Glanzman, a senior author of the study, and a UCLA professor of integrative ...

Not all species may suffer from climate change. A new analysis shows that Dolly Varden, a species of char common in southeast Alaska, adjust their migrations so they can keep feasting on a key food source - salmon eggs - even as shifts in climate altered the timing of salmon spawning. The resiliency of species to climate change may depend on how well they adapt to climate-driven changes in their food and habitat, such as altered growth of plants they feed on. A mismatch in timing between predators and the availability of prey could cause some species to lose access to ...

About 15 percent of women in the United States suffer from anxiety disorders and depression during their pregnancies, and many are prescribed antidepressants. However little is known about how early exposure to these medications might affect their offspring as they mature into adults. The answer to that question is vital, as 5 percent of all babies born in the U.S. - more than 200,000 a year - are exposed to antidepressants during gestation via transmission from their mothers. Now, a UCLA team has studied early developmental exposure to two different antidepressants, ...

HOUSTON - (Dec. 19, 2014) - An atomically thin material developed at Rice University may lead to the thinnest-ever imaging platform. Synthetic two-dimensional materials based on metal chalcogenide compounds could be the basis for superthin devices, according to Rice researchers. One such material, molybdenum disulfide, is being widely studied for its light-detecting properties, but copper indium selenide (CIS) also shows extraordinary promise. Sidong Lei, a graduate student in the Rice lab of materials scientist Pulickel Ajayan, synthesized CIS, a single-layer matrix ...

PROVIDENCE, R.I. [Brown University] -- Neutrophils, a type of white blood cell, are the immune system's all-terrain vehicles. The cells are recruited to fight infections or injury in any tissue or organ in the body despite differences in the cellular and biochemical composition. Researchers from Brown University's School of Engineering and the Department of Surgery in the Warren Alpert Medical School collaborated to devise a new technique for understanding how neutrophils move in these confined spaces. The technique involves two hydrogel sacks sandwiched together with ...

PHILADELPHIA - (Dec. 19, 2014) - A common polymorphism - a variation in a person's DNA sequence that is found with regularity in the general population - can lead to a chain of events that dictates how a tumor will progress in certain types of cancer, including a form of breast cancer as well as ovarian cancer, according to new research from The Wistar Institute that was published online by the journal Cancer Cell. The research reveals a more explicit role about the symbiotic relationship humans have with the various bacteria that inhabit our body and their role during ...

(Edmonton) For millions of people around the world, televised medical talk shows have become a daily viewing ritual. Programs such as The Dr. Oz Show and The Doctors have attracted massive followings as charismatic hosts discuss new medical research and therapies while offering viewers their own recommendations for better health. For show producers it's a winning ratings formula, but for viewers eager for a healthier life, the results aren't so clear cut. "The research supporting any of these recommendations is frequently absent, contradictory or of poor quality," says ...

Women whose loved ones are critical of their weight tend to put on even more pounds, says a new study on the way people's comments affect our health. Professor Christine Logel from Renison University College at the University of Waterloo led the study, which appears in the December issue of the journal Personal Relationships. "When we feel bad about our bodies, we often turn to loved ones--families, friends and romantic partners--for support and advice. How they respond can have a bigger effect than we might think," said Professor Logel, who teaches social development ...

WASHINGTON D.C., December 19, 2014 - Researchers at Montana State University and Brandenburg University of Applied Sciences in Germany have created a simple mathematical model based on optical measurements that explains the stunning colors of Yellowstone National Park's hot springs and can visually recreate how they appeared years ago, before decades of tourists contaminated the pools with make-a-wish coins and other detritus. The model, and stunning pictures of the springs, appear today in the journal Applied Optics, which is published by The Optical Society (OSA). If ...

Despite showing interest in web or mobile apps to help manage their Type 2 diabetes, only a small number of older adults actually use them, says a new study from the University of Waterloo. Approximately 2.2 million Canadians are living with Type 2 diabetes, 2 million of whom are age 50 or older. The study, which appears in the online edition of the Journal of Diabetes Science and Technology, found that although more than 90 per cent of research participants owned a computer or had daily Internet access, just 18 per cent used applications on this technology to help manage ...

The lithium-ion batteries that mobilize our electronic devices need to be improved if they are to power electric vehicles or store electrical energy for the grid. Berkeley Lab researchers looking for a better understanding of liquid electrolyte may have found a pathway forward. A team led by Richard Saykally, a chemist with Berkeley Lab's Chemical Sciences Division, David Prendergast, a theorist with Berkeley Lab's Molecular Foundry, and Steven Harris, a chemist with the Lab's Materials Sciences Division, found surprising results in the first X-ray absorption spectroscopy ...

It's like a scene from a gamer's wildest dreams: 12 high-definition, 55-inch 3D televisions all connected to a computer capable of supporting high-end, graphics-intensive gaming. On the massive screen, images are controlled by a Wii remote that interacts with a Kinnect-like Bluetooth device (called SmartTrack), while 3D glasses worn by the user create dizzying added dimensions. But this real-life, computer-powered mega TV is not for gaming. It's for engineering. Welcome to Brigham Young University's VuePod, a 3D immersive visualization environment run by BYU's Department ...

As hospitals and health systems increasingly focus on addressing the rising cost of health care in the United States, and with the expense of surgical care playing a major role, physician researchers and others across the healthcare industry are working to identify innovative ways to reduce surgical costs. In new findings published online in the journal Annals of Surgery on December 19, 2014, researchers determined ...

Researchers from the University of Southampton have revealed a breakthrough in optical fibre communications. Academics from the University's Optoelectronics Research Centre (ORC) have collaborated with colleagues at Eblana Photonics Inc, in Ireland, to develop an approach that enables direct modulation of laser currents to be used to generate highly advanced modulation format signals. The research, published in the journal Nature Communications, explores a radically new approach to the generation of spectrally-efficient advanced modulation format signals as required ...

Carnivorous plants catch and digest tiny animals in order and derive benefits for their nutrition. Interestingly the trend towards vegetarianism seems to overcome carnivorous plants as well. The aquatic carnivorous bladderwort, which can be found in many lakes and ponds worldwide, does not only gain profit from eating little animals but also by consuming algae and pollen grains. This results in survival in aquatic habitats where prey animals are rare, and in increased fitness if the animals and algae are caught in a well-balanced diet. An Austrian research group around ...

Over the past decade, ocean acidification has received growing recognition not only in the scientific area. Decision-makers, stakeholders, and the general public are becoming increasingly aware of "the other carbon dioxide problem". It is time to reflect on the successes and deficiencies of ocean acidification research and to take a look forward at the challenges the fastest growing field of marine science is facing. In the January issue of the journal Nature Climate Change Ulf Riebesell, professor for Biological Oceanography at GEOMAR Helmholtz Centre for Ocean Research ...

Bremerhaven/Germany, 18 December 2014. Ingestion of microplastic particles does not mechanically affect marine isopods. This was the result of a study by biologists at the North Sea Office of the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) that was published recently in the journal Environmental Science and Technology. The study marks the launch of a series of investigations aimed at forming a risk matrix on the sensitivity of different marine species to microplastic pollution. Uptake of large plastic items by birds and fish may cause ...

In a recent study from Lund University in Sweden, researchers have used new technology to study extremely fast processes in solar cells. The research results form a concrete step towards more efficient solar cells. The upper limit for the efficiency of normal solar cells is around 33 per cent. However, researchers now see a possibility to raise that limit to over 40 per cent, thereby significantly improving the potential of this energy source. The experiments in the present study involved 'juggling' on quantum level with photons, i.e. light particles, and electrons. ...

In everyday life, the global positioning system (GPS) can be employed to reliably determine the momentary location of one en route to the desired destination. Scientists from the Institute of Physical and Theoretical Chemistry of the University of Bonn have now developed a molecular "GPS" with which the whereabouts of metal ions in enzymes can be reliably determined. Such ions play important roles in all corners of metabolism and synthesis for biological products. The "molecular GPS" is now being featured in the journal Angewandte Chemie. There would be no life on our ...

Bethesda, MD (Dec. 19, 2014) -- A new formulation of oral budesonide suspension, a steroid-based treatment, is safe and effective in treating pediatric patients with eosinophilic esophagitis (EoE), according to a new study in Clinical Gastroenterology and Hepatology, the official clinical practice journal of the American Gastroenterological Association. Eosinophilic esophagitis is a chronic immune system disease caused by a buildup of white blood cells in the lining of the esophagus. This build up, which is a reaction to food, allergens or acid reflux, can inflame or injure ...

The changes can be measured, but their reasons were unknown. For several decades, scientists have carefully observed that the oxygen minimum zones (OMZ) in the tropical oceans are expanding. These zones are a paradise for some specially adapted microorganisms, but for all larger marine organisms such as fish and marine mammals they are uninhabitable. Thus, their expansion has already narrowed down the habitat of some fish species. Marine scientists from the GEOMAR Helmholtz Centre for Ocean Research Kiel and the Kiel Collaborative Research Centre (Sonderforschungsbereich, ...

PITTSBURGH--University of Pittsburgh researchers have shared their findings from three studies related to shale gas in a recent special issue of the journal Energy Technology, edited by Götz Veser, the Nickolas A. DeCecco Professor of Chemical and Petroleum Engineering in Pitt's Swanson School of Engineering. In the special issue focusing on shale gas, Pitt faculty authors look at "smart wells" that use wireless communication, wastewater management, and information gaps between legislators, regulators, industry representatives, researchers, and the public on the ...
