NASA's SDO captures images of 2 mid-level flares

NASA's SDO captures images of 2 mid-level flares
2014-12-19
(Press-News.org) 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, the U.S. government's official source for space weather forecasts, alerts, watches and warnings.

This flare is classified as an M6.9-class flare. M-class flares are a tenth the size of the most intense flares, the X-class flares. The number provides more information about its strength. An M2 is twice as intense as an M1, an M3 is three times as intense, etc.

Updates will be provided as needed.

Lost memories might be able to be restored, new UCLA study indicates

Lost memories might be able to be restored, new UCLA study indicates
2014-12-19
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 ...

Alaska fish adjust to climate change by following the food

Alaska fish adjust to climate change by following the food
2014-12-19
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 ...

Early exposure to antidepressants affects adult anxiety and serotonin transmission

Early exposure to antidepressants affects adult anxiety and serotonin transmission
2014-12-19
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, ...

Atom-thick CCD could capture images

Atom-thick CCD could capture images
2014-12-19
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 ...

New technique reveals immune cell motion

2014-12-19
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 ...

A polymorphism and the bacteria inside of us help dictate inflammation, antitumor activity

A polymorphism and the bacteria inside of us help dictate inflammation, antitumor activity
2014-12-19
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 ...

Televised medical talk shows: Health education or entertainment?

Televised medical talk shows: Health education or entertainment?
2014-12-19
(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 ...

Family criticizing your weight? You might add more pounds

2014-12-19
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 ...

Yellowstone's thermal springs -- their colors unveiled

Yellowstones thermal springs -- their colors unveiled
2014-12-19
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 ...

Technophobia may keep seniors from using apps to manage diabetes

2014-12-19
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 ...
