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.

Space Science image of the week is this striking perspective view from ESA's Mars Express. It shows an unnamed but eye-catching impact crater on Mars. This region sits south-west of a dark plain named Mare Serpentis (literally ‘the sea of serpents'), which in turn is located in Noachis Terra (literally ‘the land of Noah').
Noachis Terra is one of the oldest known regions on the Red Planet, dating back at least 3.9 billion years— in fact, the earliest martian era, the Noachian epoch, is named after it. Noachis Terra is representative of ancient Mars' surface, which is characteristically peppered with craters that have been preserved for billions of years, although many have degraded over time.
The crater visible on the top right of this image is around 4 km deep and 50 km in diameter. At its very centre is a small depression known as a central pit. These are common in craters on rocky worlds throughout the Solar System, especially on Mars, and are thought to form as icy material explosively vaporises and turns to gas in the heat of the initial crater-forming collision.
The outer walls around the crater are slightly raised above its surroundings. These stacked deposits may have formed during the impact that carved out the crater itself. As a rocky impactor slammed into the surface of Mars it likely compacted the loose and powdery material — small-grained dust and soil dubbed ‘regolith' — to form a small plateau that has stood the test of time.
Just within the crater walls are channels and valleys threading and weaving down the inner slope — these are thought to have been carved and sculpted by running water. This water, locked up within the soil as groundwater and ice, would have melted as the Sun illuminated the crater walls, driving fluvial erosion processes and sketching thin lines down towards the centre of the crater.
This image was created using data from the Mars Express High Resolution Stereo Camera's stereo channels (resulting in this oblique perspective) as well as its colour and nadir channels (creating the colour). The data were obtained on 29 July 2015 during orbit 14680. The resolution is approximately 14 m per pixel and the image is centred at 37° East and 35° South.
The image is a perspective view from a series that includes a colour nadir view, a colour-coded digital terrain model and a 3d anaglyph.

This image was taken by the NASA/ESA Hubble Space Telescope's Advanced Camera for Surveys (ACS) and shows a starburst galaxy named MCG+07-33-027. This galaxy lies some 300 million light-years away from us, and is currently experiencing an extraordinarily high rate of star formation — a starburst.
Normal galaxies produce only a couple of new stars per year, but starburst galaxies can produce a hundred times more than that. As MCG+07-33-027 is seen face-on, the galaxy's spiral arms and the bright star-forming regions within them are clearly visible and easy for astronomers to study.
In order to form newborn stars, the parent galaxy has to hold a large reservoir of gas, which is slowly depleted to spawn stars over time. For galaxies in a state of starburst, this intense period of star formation has to be triggered somehow — often this happens due to a collision with another galaxy. MCG+07-33-027, however, is special; while many galaxies are located within a large cluster of galaxies, MCG+07-33-027 is a field galaxy, which means it is rather isolated. Thus, the triggering of the starburst was most likely not due to a collision with a neighboring or passing galaxy and astronomers are still speculating about the cause. The bright object to the right of the galaxy is a foreground star in our own galaxy.

The D&T Association has launched its D&T Heroes campaign, which it says looks to “promote and celebrate the value of design”.
The social campaign has been introduced in response to a parliamentary debate about the English Baccalaureate a GCSE qualification that excludes art and design earlier this month. The debate was triggered by a petition called “Include expressive arts subjects in the EBacc”.
Running for at least six months, D&T Heroes encourages anyone to submit their favourite designer, product or object spanning everything from industrial to technology design to its various social media sites.
The responses will be then collated into a book featuring the best British and international design heroes, complete with comments from design experts, before being signed by organisation partners and supporters and delivered to the Department of Education and the Department for Business Innovation and Skills.
Organisations that have signed up in support of the campaign so far include the RSA; Crafts Council; Creative & Cultural Skills; Design Museum; V&A; The Institution of Civil Engineers and The Institution of Engineering and Technology.
The campaign and the forthcoming book are intended to act as “a powerful statement about the importance and relevance of design and technology in education, industry and society”, according to the D&T Association.
From September, the campaign will also be launched in schools as a teaching resource that supports the D&T curriculum at several Key Stage levels.
The planned introduction of the book into school curriculum is designed to inspire pupils, teachers and parents to participate in the campaign, but will also act as “visual history” of design and technology that could be used as the basis for activities such as homework assignments, Design Week understands.
Submissions can be uploaded to Facebook, Twitter or Instagram with the hashtag #DandTHeroes

“If the past is another country, the language they speak there is very exotic. Let these words instantly transport you back to 1992: Safmat, Omnicrom, Syquest, Zip, Jaz, Quark, Bromide and (whisper it) SCSI Probe. My time at the University of Northumbria in Newcastle was filled with such linguistic delights (as well as Viz and massive Stottie cakes). It's difficult to name a single stand-out project, as everything felt like such a revelation: using prehistoric Macs for the first time, the squeegee-powered joy of screenprinting, setting metal type, messing around with Hasselblads and Super-8s… all new, all amazing. But the project where it all came together was the final year D&AD student brief set by Pat Baglee, then of the charity Scope. Through that project, I understood the full range of skills required of me as a designer: listener, thinker, planner, writer, conceptualiser, typographer, photographer, art-worker. Design, I then realised, was brilliant. And flipping hard work.”
“Well, I did a packaging project for The Science Museum. Each item became a practical scientific experiment. Who knew that you can boil water in a paper bag or look over walls with a poster tube? (Other items included a hot air balloon bag and something fun with postcards, etc.) Yes, the type was lousy (it was hand spaced!), the logo went too far. Would I do it differently now? Sure, but the concept of encouraging you to think about the science that is around us every day is spot on. In fact, it's more relevant to the museum now than when I did it. Maybe they should call me?”
“My time at university was at the beginning of the digital revolution as we know it now. A lot of time was invested in the learning of applications such as Macromedia Director and After Effects without any guidance from tutors who were oblivious to the power of these programs. As a result, my learning was at times chaotic and not the best use of my precious college time. It was against this backdrop of banging my head against a wall that I decided to stop my projects being driven by the software and let the ideas come first. I created a rather ropey identity for an internet radio station named ibiza.fm, an innovation idea where DJs would broadcast sets direct to listeners all over the world, without a Radio1-like partner in-between. In 2000, this was still ahead of the times and it reflects many of the services that exist today sixteen years later. It was my first step towards learning the best brands use great ideas delivered with great technology. Without that combination, you're a step behind.”

In running the Urban Caracal Project there have been a number of learning opportunities. One of our most important insights is that by prioritizing public outreach we have built a strong community support group without which the project would be impossible. The community support has not just been integral to large-scale funding efforts, but also help with special project needs that sometimes seem impossible. It is when the community has stepped up that some of the most gratifying and memorable leaps in project success have happened. In our case, the African proverb of “it takes a village” is particularly apt, as it has taken a village to make the Urban Caracal Project successful.
The story of Tyger, a young male caracal that was the 16th that we radio-collared, is memorable on multiple fronts. First off, he is a survivor. As is common for our urban caracals, Tyger was hit by a car in the northern suburbs of Cape Town late last year. While most vehicle collisions end in death for caracals, Tyger was lucky that he escaped with only one broken leg. Perhaps more importantly, he was lucky that the community took action to ensure his survival; community members called the Cape of Good Hope SPCA who brought him in for rehabilitation. “Only a broken leg” is not a promising diagnosis for a wild carnivore because their survival depends their ability to travel far to hunt and find mates. For the lucky Tyger, however, the SPCA was optimistic that if the leg could heal, he would survive. And so the SPCA worked tirelessly to rehabilitate him, first with surgery to fix his broken leg, and then careful monitoring and feeding him as he healed and rebuilt his strength.
Within a couple of months Tyger was ready to be radio-collared and released. With the help of more community members, South Africa National Parks, the SPCA, the City of Cape Town and a handful of international volunteers, we were able to release him into the Tygerberg Reserve. This reserve is the nearest patch of natural habitat that is large enough to be able to support caracals near the suburbs where Tyger was initially found. Because of our limited number of available collars, we used a radio-collar that had only half of it's battery life left after it was recovered from the body of another caracal (Berg Wind, who had died from disease). But it would allow us to monitor his movements briefly, and whether he survived his release post-rehabilitation.
We expected that Tyger would remain in, or nearby, the reserve until his radio-collar ran out of battery power. But after only 10 days of laying low in the urban reserve, Tyger started an unexpected journey. He found a narrow strip of relatively connected habitat to make his exit from the reserve (map above), and then headed straight north all the way to Malmesbury! All told this was a 55 kilometer trek, suggesting that his leg was not a hindrance.
Tyger himself taught us important lessons. He is the only caracal we have radio-collared outside of our isolated, urban Cape Peninsula study area. As a young two year old male, he appears to have been in dispersal mode (looking for an unoccupied territory to call his own). Successful dispersal is important for wild cats because it is a natural deterrent to inbreeding in populations. Our data is suggesting that our Cape Peninsula population is severely isolated by urbanization, and so far we have not seen any individuals successfully disperse outside of our study area. Our early data suggests that in this landscape isolated by a sea of water and dense urban development, successful dispersal may not be possible.
Tyger's story could be one of success. As we expected, Tyger's collar reached the end of its battery life in mid-March, and at that time he seemed to have settled down in the Malmesbury area. The last of his movements spanning approximately 6 weeks suggest he was exploring a potential territory of his own.
To ensure that the project caracals are not stuck wearing radio-collars for the entirety of their lives, we use multiple measures to ensure that the collars drop off. We then attempt to recover the collars to ensure it has indeed fallen off of the animal and to recover the data from the collar that we could not remotely access. When the battery on Tyger's collar died we were able to send a signal remotely, through a web interface, to the radio-collar to have it fall off. The “drop-off” activation through the website has proven effective on other caracal studies in South Africa, but it doesn't always work. Therefore, we followed up to recover the collar in the areas where Tyger's radio-collar collected data. We spent days and days driving around trying to hone in on a radio-signal. Unfortunately we had no luck; we were not even able to hear the signal.
In cases like these, where we cannot hear the radio-signal from collar from the ground, it can be more effective to fly over the area to listen for the collar from above. As lead researchers on the project, we'd never even considered flights because of our limited budget. But we grew desperate to recover the collar, and with the knowledge of how far our community had carried the project to that point, we got creative. We reached out to our community supporters once again and posted a request on our Facebook page for volunteer help in scheduling a flight. Amazingly, our community came through yet again, and Ross Leighton and Stephan Moser from The Morningstar Aviation Club were able to get us up in the air within 12 hours of our Facebook post.
Despite the help, we were not able to find the radio-collar. But after the flight we could take solace in the fact that we had done all we could. After all our exhaustive searching, we now believe the collar fell off of Tyger and was then buried in sand. This is a problem we have seen in the past, and as the collar gets buried in sand the signal became too faint to hear.
The caracals on our project are resilient and adaptable. They seem to do remarkably well even in landscapes fragmented by agriculture and urbanization. But because this is in an environment where increasing fragmentation is occurring, it is important to try to retain what habitat connectivity remains; not just for caracals, but for the many other species that are trying to survive in the urbanizing landscape. Urbanization is the principle threat to global biodiversity conservation, and habitat loss and modification due to urbanization is going to continue at a rapid pace across the globe. It is important that if we want to try to protect biodiversity in the changing landscape, we protect areas that animals can move through to maintain functional habitat connectivity in fragmented landscapes.
It seems daily that we find ourselves counting our blessings to be doing the work within the supportive community of Cape Town. Our Cape Town “village” has helped this project function on many fronts, financially and logistically, as well as with their enthusiastic interest! So the project continues to survive and even thrive despite the various challenges that always crop up on large field projects.
The Urban Caracal Project is a cooperation between the Cape Leopard Trust, the University of Cape Town, University of California, Santa Cruz, the City of Cape Town, and South Africa National Parks, and the many private landowners around Cape Town.

"Really? You and the Florida legislature worked like mad dogs to reject, refuse and to deny the ability of the U.S. EPA to regulate fertilizers including nitrogen and phosphorous, the cause of the algae blooms. And you want the federal taxpayer to rescue you because of your own stupidities? When the federal government offered to assist in regulating fertilizers, you said 'no thanks'. Then you set the Florida Chamber of Commerce and Associated Industries of Florida loose on Congress. When we have tried to move Everglades restoration forward, your administration has pushed back against any efforts to put tighter restrictions on phosphorous and nitrogen flowing from sugar fields owned by your buddies, the Big Sugar cartel. So who are you kidding with your complaints about the federal government not stepping in and being active? We tried. You denied. We promoted the U.S. economy and environmental stewardship and you demagogued against pollution control laws because they "kill jobs". You kicked us out and then you cut your own agencies' science staff to the bone. Next time you call, give me some good news; like you support buying enough land in the Everglades Agricultural Area to stop the use of Florida waterways as sacrifice zones for Big Sugar."

Of the eighteen issues Pew examined in early 2016, 47% said "protecting the environment" should be a top priority. The issue ranked low--thirteenth of 18 issues the pollsters examined...These low rankings don't mean that Americans no longer care about the environment. Having a clean and healthful environment is a core value for most people. What the responses probably tell us is that Americans think policymakers, regulators, and activists are paying sufficient attention to environmental issues and that they want them to turn their attention to more pressing concerns...On occasion, however, a specific environmental problem can elevate the general issue in importance. Is the unsafe lead level in Flint Michigan's drinking water such a problem? We know from work by survey organizations such as Gallup that problems people can see in their communities such as air and water pollution tend to concern Americans more than issues that seem distant. As Gallup noted in a release in March, polluted drinking water and pollution of rivers, lakes and reservoirs "have consistently topped Americans' concerns during the 27 years the organization has been measuring environmental attitudes." This year, 61% told Gallup they worried a great deal about pollution of drinking water, and 56% gave that response about polluted waterways. Concern about both was up slightly from 2015.

Cat-Heads with Spinach and Mushroom Gravy (and no Cats)
Cat-heads are biscuits, big ones (cat-head-sized, if you're into hyperbole). Beloved in the south, they're tall, fluffy, and alas, traditionally made with lard. This vegan version may upset southern traditionalists, but their slight but pleasing tang and light texture honors the original without pork fat or harm to pig. No traditional milk-and-pork-fat gravy , but a plant-based one. Lemon zest can stand in for harder-to-find sorrel and everyday button mushrooms replace pricy chanterelles.
If like my dad, you prefer sweet to savory, skip the spinach and mushroom gravy, enjoy another southern tradition, biscuits and sorghum syrup.
For the biscuits:
-- Use a light hand with the dough. Even better, use a food processor. The whole batch comes together in minutes.
-- Chilled vegan butter. It keeps the dough cool so the fat melts into the biscuit dough only during baking.
-- Many southern cooks swear by White Lily flour, a soft wheat flour. I've adjusted by adding corn starch to unbleached all-purpose flour for lighter biscuits.
-- Biscuits always taste best fresh out of the oven.
1/2 cup unsweetened soy milk
1 tablespoon cider vinegar
1-3/4 cups unbleached all-purpose flour, plus additional for shaping biscuits
3 tablespoons cornstarch
4-1/2 teaspoon aluminum-free baking powder
pinch sea salt
6 tablespoons) vegan butter or margarine, chilled
1 tablespoon vegan butter or margarine, melted (optional)
Preheat oven to 400 degrees. Line a rimmed baking sheet with parchment paper.
In a small bowl, whisk together soy milk and cider vinegar to make vegan buttermilk (mixture will clabber -- it's supposed to). Set aside.
In a food processor, sift together flour, cornstarch, baking powder and salt. Pulse a time or two to combine.
Pulse in the chilled vegan margarine and mix quickly, just until mixture becomes like coarse meal. Pour in vegan buttermilk and give a quick mix to form a damp dough.
Dust rolling surface generously with more flour. Turn out the biscuit dough. Knead oh-so-briefly, working in flour -- a tablespoon or two at a time -- just until dough loses its stickiness. Pat or roll out dough to 1/2-inch thick. Flour the rim of a glass or use a floured 2-inch or 3-inch biscuit cutter to form biscuits.
Place biscuits on the rimmed baking sheet. Brush tops with melted vegan butter, if desired.
Bake for 15 minutes. Biscuit should be lightly golden, pillowy and fragrant. Best served at once, with a generous ladleful of gravy.
Makes 6 to 8 biscuits, serving 6 to 8.
For the spinach and mushroom gravy:
2 tablespoons olive oil
1 clove garlic, chopped
2 scallions, green tops and thick white stems, chopped
8 ounces mushrooms, chopped
4 ounces spinach leaves
1 handful sorrel leaves, if you can get them or 1 lemon, zested
1-1/2 teaspoons nutritional yeast
1/4 cup plain unsweetened soy milk
sea salt and fresh ground pepper to taste
Heat olive oil in a skillet over medium-high heat. Add chopped garlic, scallions and mushrooms. Saute, giving the vegetables an occasional stir, for about 4 to 5 minutes, or until they're softened.
Cover and reduce heat to low, cooking another 10 minutes or until mushrooms have darkened and produced a nice amount of broth.
Add spinach leaves by the handful, the sorrel if you can get it, or the lemon zest if you can't. Stir just until the greens go limp, another minute or two.
Pour everything into a blender or food processor, scraping up any mushroom bits that stick to the bottom of the pan. Add soy milk and nutritional yeast. Give a quick puree until sauce thickens and becomes smooth and green. Season with sea salt and pepper. Spoon over biscuits or pair with any fresh vegetable.
Makes roughly 1 cup, serving 4 to 6.

Talks in Vienna to limit the super-warming chemicals called hydrofluorocarbons (HFCs) under the Montreal Protocol kicked into high gear on Friday and Saturday. The first phase of the nine-day negotiating session ended favorably in the wee hours of Sunday morning with agreement on key “challenges and solutions.”
That agreement paves the way for countries to spend the week ahead coming to terms on the central issues: ambitious schedules for freezing and phasing down HFC production and use in both developed and developing countries, and financial assistance to help developing countries achieve their phase-down commitments.
The upbeat mood of the first two days, evident in the words and actions of nearly all parties, further raises expectations that this is the year for agreeing on an HFC amendment.
The goal for the Vienna meeting is to get close enough to a complete agreement on phase-down schedules and financing provisions that countries can seal the deal on a final HFC amendment to the Montreal Protocol when they meet in Kigali, Rwanda, in October.
The stakes are high. Left unchecked, HFC production, use, and emissions are rising fast. An treaty amendment this year could prevent, between now and 2050, HFC emissions with a warming power equal to nearly three times the world's current annual output of carbon dioxide. This would be the biggest climate protection achievement of 2016 and help power the Paris Climate Agreement forward.
The Sunday-morning agreement addresses the main principles to govern financial assistance to help developing countries meet HFC phase-down commitments. The parties agreed to continue using the Montreal Protocol's Multilateral Fund (MLF) the mechanism through which donor countries helped developing countries phase out chlorofluorocarbons (CFCs) and many other ozone-destroying and climate-damaging chemicals and to provide “sufficient additional financial resources” to help those countries meet new HFC commitments. They agreed on a list of activities eligible for funding, and on a process for the MLF to adopt detailed guidelines.
The Sunday-morning agreement reassures countries that the MLF will cover the costs of licensing patents where needed. Patent issues have been a point of contention in past negotiations, although recent research presented at the meeting has helped cut this problem down to a resolvable size. The agreement also asks the MLF to look at ways to support enhancing the energy efficiency of air conditioners and other equipment in tandem with adopting new refrigerants.
The agreement also opens the door for making certain exemptions available as the phase-down proceeds. This is a tried-and-true mechanism for addressing the fear that alternatives won't be ready for some uses when phase-down limits kick in. The possibility of hard-case exemptions makes it acceptable for countries to agree up front to ambitious reduction schedules.
Negotiators' enthusiasm palpably increased with every “challenge” met and “solution” found.
India and China are joining the U.S., Canada, Mexico, European Union and others in down-to-earth problem solving. Even Saudi Arabia, in the past an obstacle, is contributing to progress.
What's next? Negotiators will work all next week to develop the specific language of the HFC amendment, building from four existing proposals and the “solutions” adopted this weekend. On Friday and Saturday, ministers from around the world will convene for a high-level “Meeting of the Parties.” The U.S. will be represented by EPA Administrator Gina McCarthy as well as high-level White House and State Department officials.
The goal is to get as close as possible to a final deal, so that the ministers can close the remaining gaps this week and in the months ahead, and sign the long-awaited HFC phase-down amendment to the Montreal Protocol in Kigali this October.
We'll provide further updates as the week's talks proceed.

Stunning blue waters surround and pass through the tidal channels of islands in the Bahamas. Small tidal changes on the banks cause water to flow through the narrow channels between the islands, first in one direction and then the other. The darker blue sections of water are the deepest parts of the channels and the surrounding light blue color is more shallow (less than 25 meters / 80 feet).

This is the view that you get from the terrace bar at the SkyLounge in the Hilton hotel in Tower Hill. They were nice enough to let me come by and set up my tripod at sunset and capture the evening view. I got the pink haze at the top of the frame as the sunlight reflected off the horizon.

When doctors hurl toxic death at cancer cells, often a few will survive and come back. A family of enzymes called KDM5 histone demethylases is emerging as important for this resilience and drugs that inhibit KDM5 enzymes could be active in treating several types of cancer. A team of investigators obtained detailed structural information, showing how inhibitors of the KDM5 family interact with their targets by building a molecular model of the KDM5A enzyme, along with an inhibitor bound in the active site. Their findings could inform efforts to design more potent and selective anticancer drugs.

This is the first image ever captured of blue jet lightning. It was taken at Arecibo Observatory in Chile. A team of researchers at Arecibo captured video evidence from the ground of this lightning phenomenon known as blue jet. The discovery is the first ground-based evidence linking the ionosphere with cloud tops in blue jet events. According to Victor Pasko of Penn State University, an electrical engineer working at Arecibo, pilots and others reported observations of red sprites and blue jets long before the first one was captured on video, and numerous undocumented reports of similar phenomena have appeared in scientific literature for over a century.
