A large study suggests that radiologists vary widely in their assessment of density, a risk factor for breast cancer. And density is just one factor in breast-cancer risk, the researchers underscore.
Federal and Utah health officials are investigating a case that may be the first instance of Zika spreading from one person to another in ways other than via mosquito bites, sex or the placenta.

Duplin County, North Carolina is the epicenter for industrial swine production in the United States. Housing an estimated 2.2 million hogs, this dot on the map shoulders more than its fair share of the world's swine production load. I showed up last summer to film the stories of those trying to protect the water, land, and air that these hog farms influence so profoundly.
First, what's the problem? Everyone loves pig right? Vitamin B (bacon) is certainly a staple of my brunch diet. In short, the sheer number of hog farms that have slid into this predominantly minority, low-income community has stressed its environment to the max. A pig produces about ten times as much waste as a human does, yet has almost none of the regulations on how it's disposed.
In North Carolina, contract farmers working under the umbrella of a far away corporation have few choices on how to handle the hog waste from the scores of animals they are forced to grow to stay profitable. This waste typically flushes into “lagoons” then when the that fills up, farmers spray the tepid liquid waste filled with the most unimaginable grossness on to fields as fertilizer. This works in many cases, but all too often overstressed farmers (no one has it easy here) over-apply and allow runoff into local streams, all the while pumping the air full of toxic stench. The standard industry response that “it's not that bad” doesn't cut it for some.
Enter René (family name withheld.) She lives in the same neighborhood she grew up in, a house handed down from her mother. In the late 1990s an industrial swine “farmer” set up a spray field across the street from her house. Several times every week, the “farmer” pumps this grotesque cocktail of pig excrement into the air 20 yards from her front door. René has developed respiratory issues, and can't go outside without quickly becoming hoarse. She no longer can hang clothes to dry or work in her garden, lingering outside just long enough to get to her car to go to and from work.
Despite these hardships René still manages to smile and get along with her life. Although she has much to be afraid of, she carries no fear, no hatred, and says she'll speak out until her last breath. Her story is not unique, but her courage is.
Numerous groups are taking on the science behind what's happening to the air and water around these “farms.” Devon Hall, co-founder of Rural Empowerment Association for Community Health (REACH) is spreading the scientific gospel as a way to empower these communities to speak up about these injustices. The Waterkeeper Alliance also leads countless research efforts to document, in clear black and white, what these polluters are doing. Merely imagining breathing in pig excrement and drinking tainted water supplies doesn't do much to convince an industry-owned government of anything. Duplin County is finding science as savior and rising up to prove, in no uncertain terms, it is that bad

Why do people sext? Why do they send racy or naked photos or videos and sexually loaded texts?
For a short-term hookup, sexting might seem like a direct way to get what you want - or at least try to. But according to my research, sexting is actually most likely to occur within a committed relationship. Some research suggests that people often engage in sexting after being coerced by romantic partners or to avoid an argument with their romantic partner. So perhaps anxiety and concern about what your romantic partner thinks about you promote behaviors like sexting.
As a human development researcher who studies how technology influences relationships, I wanted to understand if people who are anxious about dating or about what their partner thinks of them are more likely to sext.
One of the major theories regarding relationships is called attachment theory. It suggests that the way you related to your caregiver as an infant (and vice versa) shapes how you come to view relationships later in life.
If your caregiver was attuned to your needs and responsive, you will develop a secure attachment. That means you are comfortable with close relationships because your experience paid off - Mom or Dad was there when you were distressed or hungry or cold. From that experience, you learned that relationships are safe and reciprocal, and your attachment anxiety is low.
But if your caregiver was not so attuned to your needs, was intrusive or inattentive, you might develop what is called an insecure attachment. If something you wanted emotionally or physically (like comfort) went unfulfilled, you might end up anxious about relationships as an adult. You might realize that relationships may not be trustworthy, not invest in close relationships, and avoid intimacy all together.
My colleagues, Michelle Drouin and Rakel Delevi, and I hypothesized that people who were afraid of being single or had dating anxiety and who were, at the same time, anxious or insecure in their attachment style would be more likely to sext. We also thought these singles would be more likely to sext their romantic partners, even when their relationship wasn't very committed.
We gave 459 unmarried, heterosexual, undergraduate students an online questionnaire to learn more about how relational anxiety influences sexting behavior. It covered questions measuring their sexting behaviors, relationship commitment needed to engage in sexting, their fear of being single, their dating anxiety and their attachment style (secure or insecure). Half of the people who took the survey were single, and about 71 percent were female.
We found that people in romantic relationships -- whether of long or short duration - were more likely to have sexted than those who did not have romantic partners. There were no gender differences for engaging in sexting, except that males were more likely than females to have sent a text propositioning sexual activity.
We also found that, generally, dating anxiety from fear of negative evaluation from the romantic partner (basically, worrying about what your partner thinks of you) and having a more secure attachment style (i.e., comfort with intimacy and close relationships) predicted if someone had sent a sexually suggestive photo or video, a picture in underwear or lingerie, a nude photo or a sexually suggestive text.
We expected to find that anxiety would prompt people to sext but were surprised that comfort with intimacy related to sexting behaviors. We also expected to find that sexting would occur in relationships without a lot of commitment, meaning that we thought that sexting would be part of the wooing.
But it turns out that people who are comfortable with close relationships (a secure attachment style) and also worry about what their partner might think of them are more likely to engage in sexting, but only if there some level of commitment in the relationship.
So our hypothesis was only partially confirmed.
What this tells us is that people may be concerned with pleasing their partner's desire -- or perceived desire -- to engage in sexting and that it is the comfort with intimacy in relationships that may allow sexting to occur. And, when there is greater relationship commitment, this continues to be the case.
It appears that there is less stigma and greater comfort with sexting, provided that one perceives that his or her partner wants to sext and if there is a degree of relationship commitment.
So, a little sexting within a relationship might not be too bad.

The hidden monster at the center of Galaxy NGC 1068 can be seen in close-up in the view above from NASA's Hubble Space Telescope. NuSTAR's high-energy X-rays eyes were able to obtain the best view yet into the hidden lair of the galaxy's central, supermassive black hole. This active black hole -- shown as an illustration in the zoomed-in inset -- is one of the most obscured known, surrounded by extremely thick clouds of gas and dust.
"Although we have only detected five of these hidden supermassive black holes, when we extrapolate our results across the whole Universe then the predicted numbers are huge and in agreement with what we would expect to see," said George Lansbury, of the Centre for Extragalactic Astronomy, at Durham University.
For the first time this past fall, 2015, astronomers were able to clearly see hidden monsters that are predicted to be there, but have previously been elusive because of their 'buried' state. An international team of scientists announced having found initial evidence that poinst to a large population of hidden supermassive black holes in the Universe. Using NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) satellite observatory, the team detected the high-energy x-rays from five supermassive black holes previously clouded from direct view by dust and gas.
"For a long time we have known about supermassive black holes that are not obscured by dust and gas, but we suspected that many more were hidden from our view," says Lansbury."Thanks to NuSTAR, for the first time we have been able to clearly see these hidden monsters that are predicted to be there, but have previously been elusive because of their 'buried' state."
The Hubble Space Telescope color image above shows one of the nine galaxies targeted by NuSTAR. The high energy X-rays detected by NuSTAR revealed the presence of an extremely active supermassive black hole at the galaxy center, deeply buried under a blanket of gas and dust.
The research, led by astronomers at Durham University, UK, supports the theory that potentially millions more supermassive black holes exist in the Universe, but are hidden from view.
The scientists pointed NuSTAR at nine candidate hidden supermassive black holes that were thought to be extremely active at the center of galaxies, but where the full extent of this activity was potentially obscured from view. High-energy x-rays found for five of the black holes confirmed that they had been hidden by dust and gas. The five were much brighter and more active than previously thought as they rapidly feasted on surrounding material and emitted large amounts of radiation.
Such observations were not possible before NuSTAR, which launched in 2012 and is able to detect much higher energy x-rays than previous satellite observatories. Although we have only detected five of these hidden supermassive black holes, when we extrapolate our results across the whole Universe then the predicted numbers are huge and in agreement with what we would expect to see."
Daniel Stern, the project scientist for NuSTAR at NASA's Jet Propulsion Laboratory in Pasadena, California, added: "High-energy X-rays are more penetrating than low-energy X-rays, so we can see deeper into the gas burying the black holes. NuSTAR allows us to see how big the hidden monsters are and is helping us learn why only some black holes appear obscured."
The research was funded by the Science and Technology Facilities Council (STFC) and has been accepted for publication in The Astrophysical Journal.

“The fungi collected at the accident site had more melanin than the fungi collected from outside the exclusion zone,” says Kasthuri Venkateswaran, a senior research scientist at NASA's Jet Propulsion Laboratory. “This means the fungi have adapted to the radiation activity and as many as twenty percent were found to be radiotrophic—meaning they grew towards the radiation; they loved it.”
SpaceX and NASA are preparing the next cargo resupply mission to the International Space Station, which contains over 250 different research investigations that the space station crew will carry out over the next few months, including seven strains of fungi straight from Chernobyl, the world's worst nuclear disaster. The microbes will be grown by the crew in microgravity for two weeks before the samples are returned to Earth.
On April 26, 1986, technicians at Chernobyl's infamous reactor #4 were conducting routine systems testing when the reactor was struck by an unexpected power surge that triggered a chain of events that ultimately caused a complete meltdown, which blanketed the area in deadly radiation, turning it into a barren wasteland. During the incident, scientists estimate that the power plant released as much radioactive material into the environment as 400 atomic bombs, similar the one that devastated Hiroshima, Japan.
“Berkeley National Lab has an agreement that allows them to collect samples from the Chernobyl accident site,” explained Venkateswaran (Venkat for short), who is heading the program to send colonies of these fungi up to the space station.
“Following the accident, fungi were the first organisms to pop up in the radiation-soaked environment and scientists wanted to understand how they can thrive in such an environment.”
Venkat and NASA's Jet Propulsion Lab are just one part of a multi-institutional partnership that proposed this study, which aims to better understand how the fungi shield themselves from radiation into order to survive. The team thinks that melanin, the same dark pigment humans have in our skin, helps to shield the fungi from harmful radiation and helps convert that radiation into a food source.
Observable molecular changes within the fungi were isolated to the species collected at and around ground zero. This tells researchers that these changes were brought about by cellular stress from the radiation. They want to duplicate this process to see if new drug therapies can be derived from the fungi. Eight different species of fungi (seven from Chernobyl and one previously grown on station) will be exposed to the stresses of microgravity. The fungi colonies will grow on board the ISS for 14 days, before being returned to Earth. After the samples are returned to JPL, Venkat and his team will compare them to identical strains of fungi grown on the ground.
NASA and the world's space agencies have future missions planned for Mars, and as we move towards exploring the Red Planet and other worlds in the Solar System, having radiation-resistant plants will be a key factor in success.
At JPL, Venkat has become a leading expert in identifying microbes and preventing them from catching a ride on spacecraft. He has discovered and named 25 new organisms, including 15 since joining JPL.
