Febuxostat and ethanol mol­ecules are linked into an O—H⋯O and O—H⋯N bonded chain structure.

The crystal structure of tri­phenyl­methanol, C19H16O, has been redetermined using data collected at 295 and 153 K, and is compared to the model published by Ferguson et al. over 25 years ago [Ferguson et al. (1992). Acta Cryst. C48, 1272–1275] and that published by Serrano-González et al., using neutron and X-ray diffraction data [Serrano-González et al. (1999). J. Phys. Chem. B, 103, 6215–6223]. As predicted by these authors, the hy­droxy groups are involved in weak inter­molecular hydrogen bonds in the crystal, forming tetra­hedral tetra­­mers based on the two independent mol­ecules in the asymmetric unit, one of which is placed on the threefold symmetry axis of the Roverline{3} space group. However, the reliable determination of the hy­droxy H-atom positions is difficult to achieve, for two reasons. Firstly, a positional disorder affects the full asymmetric unit, which is split over two sets of positions, with occupancy factors of ca 0.74 and 0.26. Secondly, all hy­droxy H atoms are further disordered, either by symmetry, or through a positional disorder in the case of parts placed in general positions. We show that the correct description of the hydrogen-bonding scheme is possible only if diffraction data are collected at low temperature. The pro­chiral character of the hydrogen-bonded tetra­meric supra­molecular clusters leads to enanti­omorphic three-dimensional graphs in each tetra­mer. The crystal is thus a racemic mixture of supS and supR motifs, consistent with the centro­symmetric nature of the Roverline{3} space group.

The com­pound poly[2-hy­droxy-N-methyl­ethan-1-aminium [μ3-cyanido-κ3C:C:N-di-μ-cyanido-κ4C:N-dicuprate(I)]], {(C3H10NO)[Cu2(CN)3]}n or [meoenH]Cu2(CN)3, crystallizes in the tetra­gonal space group P43. The structure consists of a three-dimensional (3D) anionic CuICN network with noncoordinated protonated N-methyl­ethano­lamine cations providing charge neutrality. Pairs of cuprophilic Cu atoms are bridged by the C atoms of μ3-cyanide ligands, which link these units into a 43 spiral along the c axis. The spirals are linked together into a 3D anionic network by the two other cyanide groups. The cationic moieties are linked into their own 43 spiral via N—H⋯O and O—H⋯O hydrogen bonds, and the cations inter­act with the 3D network via an unusual pair of N—H⋯N hydrogen bonds to one of the μ2-cyanide groups. Thermogravimetric analysis indicates an initial loss of the base cation and one cyanide as HCN at temperatures in the range 130–250 °C to form CuCN. We show how loss of a specific cyanide group from the 3D CuCN structure could form the linear CuCN structure. Further heating leaves a residue of elemental copper, isolated as the oxide.

Do you want to track the Dodgers as the new season gets underway, but either don't have cable or are at work during the game? Maybe you want to keep an eye on the boys in blue but have an office job that gives you checks in black and white, and you want to keep your bleeding red for your favorite team from sending your bank account into the red as well. Or maybe you just aren’t going to have access to a TV at the time. Here are four ways to check the Dodgers out this season.

1. Track what’s happening with MLB.com’s free Gameday service

Want to see what’s going on as if the Dodgers game was a video game? You have to pay if you want to watch video (with alternate angles!) or listen to audio with Major League Baseball's MLB.tv service — but you can watch virtual avatars simulating the game with MLB Gameday for free. Just visit MLB.com/scores, then click on the Gameday button beneath the game you want to follow. Or, you can keep it more old school by tracking scores on the scores page — alongside video highlights.

2. Follow what’s going on on Twitter

Want to keep an eye on things but don’t want to stare at a streaming video feed? You can follow what’s happening with Twitter. The Dodgers themselves tweet highlights and results at @Dodgers, plus you can do a search for “Dodgers” or track what’s happening on various popular hashtags, including #Dodgers, #ThinkBlue and #ITFDB (It’s Time For Dodgers Baseball).

3. Listen to the radio, over the air or online

The official Dodgers radio broadcaster in L.A. is AM 570 L.A. Sports. As noted above, you can also pay to listen to audio from MLB.tv — but the service isn't available for local, "in-market" games, which are blacked out as part of their contracts with local broadcasters. The Dodgers broadcasts are also available in Spanish on 1020 AM KTNQ.

4. Stream ESPN on your computer, phone or tablet

ESPN lets you watch the opening day game and others throughout the season online... well, some of you, at least. Due to various cable company deals and other red tape, you have to already be a cable subscriber — sorry, cord cutters — but most major cable company subscribers can log in and stream the Dodgers online, or using ESPN's mobile apps available on iOS and Android. That also means you can find a friend who has cable, and team up with them to watch online — or just hang out at their place for the foreseeable future.

Many other Dodgers games throughout the season will be on SportsNet L.A., but you have to subscribe to Charter Spectrum, Time Warner, or Bright House in the L.A. area to get this channel. However, five of the games this season will be shown on KTLA, expanding your options for potentially checking the Dodgers out. You can find out more in the SportsNet L.A. FAQ.

How are you tracking the Dodgers? Let us know in the comments or by tweeting us at @KPCC.

Earth's magnetic field seems steady and true -- reliable enough to navigate by. Yet, largely hidden from daily life, the field drifts, waxes and wanes. The magnetic North Pole is currently shifting toward Siberia, forcing the Global Positioning System that underlies modern navigation to update its software sooner than expected. Every several hundred thousand years, the magnetic field dramatically shifts and reverses its polarity. Magnetic north flips to the geographic South Pole and, eventually, back again. This reversal has happened countless times over Earth's history, but scientists' understanding of why and how the field reverses is limited. The researchers find that the most recent field reversal 770,000 years ago took at least 22,000 years to complete, several times longer than previously thought. The results call into question controversial findings that some reversals could occur within a human lifetime.

The Maya of Central America are thought to have been a kinder, gentler civilization, especially compared to the Aztecs of Mexico. At the peak of Mayan culture some 1,500 years ago, warfare seemed ritualistic, designed to extort ransom for captive royalty or to subjugate rival dynasties, with limited impact on the surrounding population. Only later, archeologists thought, did increasing drought and climate change lead to total warfare -- cities and dynasties were wiped off the map in so-called termination events -- and the collapse of the lowland Maya civilization around 1,000 A.D. (or C.E., current era). New evidence unearthed by National Science Foundation-funded researchers call all this into question, suggesting that the Maya engaged in scorched-earth military campaigns -- a strategy that aims to destroy anything of use, including cropland -- even at the height of their civilization, a time of prosperity and artistic sophistication. The finding also indicates that this increase in warfare, possibly associated with climate change and resource scarcity, was not the cause of the disintegration of the lowland Maya civilization.

Today's dryku comes from H. Hanson of Pyro Spectaculars:

Because it's so dry
Professional fireworks shows
Are the way to go

Hanson actually wrote no less than five excellent drykus about the importance of professional fireworks shows during the drought. His company will be doing the fireworks at the Rose Bowl Friday night. You can get more information about that and other shows at our Fireworks FAQ. And remember to keep sending your #drykus to @kpccdryku.

Fire:

• Firefighters continue to battle a wildfire burning near Napa. Thousands of acres have burned, and more than 200 homes have been evacuated. Fire officials said the intensity is due to the bone-dry conditions. (KPCC)

Hunger:

• Tulare County and other areas hit hard by the drought have been providing food assistance to people who've lost work because of the drought. Supplies are running short, because need is more than anticipated.

Pickers aren’t the only workers hurt by the drought. Food banks are seeing some truck drivers, too. Less picking means less product to ship.

“We think [this] is going to have a devastating effect on our families,” said Wynn, adding that Visalia Emergency Aid passed out more than 500 boxes in about three weeks. “We only have 87 boxes left to last us through the rest of summer, and we serve over 800 families a month.” (Visalia Times-Delta)

Wildlife:

• The drought is driving insects from the desert into more urban areas. They're coming in search of water and nourishment. The good news is we might see more butterflies. The bad news?

Also, expect to see more roaches, black widows and ants during the summer, when they are most active, according to David Wilcox, owner of the Yucca Valley-based Sahara Pest Control that services the Coachella Valley. (The Desert Sun)

• Lakes and rivers are lower, which means less water to warm, which means warmer water, which means less oxygen in the water, which means a lot of people worried about fish. (Fresno Bee)

Wine:

• Finally, because we need some good news this morning, some wine growers/makers say that the drought is stressing their vines perfectly. That means the wine this year should be of good quality, even if there's less of it. Stock up. (CBS Sacramento)

The effects of seafloor trawling can extend further than the immediate fishing grounds, affecting delicate deep-sea ecosystems, new research suggests. In this Mediterranean study, the researchers demonstrated that clouds of sediment from trawling reached deeper habitats, increasing water-borne sediment particle concentrations to a hundred times that of background levels.

Nutella has turned into a global phenomenon, which is boosting the demand for hazelnuts. ; Credit: Ingrid Taylar/Flickr

Nutella, that sinfully indulgent chocolate-hazelnut spread, turns 50 this year, and it's come a long way, baby.

There's even a "Nutella bar" in midtown Manhattan, right off Fifth Avenue, tucked inside a grand temple of Italian food called Eataly. There's another Nutella bar at Eataly in Chicago. Here, you can order Nutella on bread, Nutella on a croissant, Nutella on crepes.

"We create a simple place," explains Dino Borri, Eataly's "brand ambassador," a man so charming that he should be an ambassador for the whole Italian country. "Simple ingredients, few ingredients. With Nutella, supertasty, supersimple. When you are simple, the people love!"

Nutella was the product of hard times. During World War II, an Italian chocolate-maker named Ferrero couldn't get enough cocoa, so he mixed in some ground hazelnuts instead. Then he made a soft and creamy version.

"It was one of the greatest inventions of the last century!" says Borri.

It's a bold claim, but greatness, you have to admit, is a matter of taste. In any case, Nutella conquered Italy and, eventually, the world.

The recipe for world domination, it turns out, isn't too complicated: Sugar, cocoa, palm oil and hazelnuts. Three of those ingredients are easy to get. Sugar, cocoa and palm oil are produced in huge quantities.Hazelnuts, though, which some people call filberts, are a different matter. Most of them come from a narrow strip of land along the coast of the Black Sea in Turkey.

Karim Azzaoui, vice president for sales and marketing at BALSU USA, which supplies hazelnuts to the U.S., says the hazelnut trees grow on steep slopes that rise from the Black Sea coast. The farms are small; grandparents and children help to harvest the nuts, usually by hand. "It's a very traditional way of life," Azzaoui says. "The Turkish family farmers are extremely proud of the hazelnut crop, as it has been part of their family history for centuries. Farmers have been growing hazelnuts here for 2,000 years."

Nutella is now making this traditional crop extremely trendy.

Ferrero, the Nutella-maker, now a giant company based in Alba, Italy, uses about a quarter of the world's hazelnut supply — more than 100,000 tons every year.

That's pushed up hazelnut prices. And this year, after a late frost in Turkey that froze the hazelnut blossoms and cut the country's hazelnut production in half, prices spiked even further. They're up an additional 60 percent this year.

Because they're so valuable, more people want to grow them. Farmers are growing hazelnuts in Chile and Australia. America's hazelnut orchards in Oregon are expanding.

And now, one can even find a few hazelnuts in the Northeastern United States, where they've never been successfully grown before. They're standing in a Rutgers University research farm, an oasis of orchards tucked in between highways, just outside New Brunswick, N.J.

"All the green leafy things you see here are hazelnut trees. But in the beginning, they all used to die from disease," says Thomas Molnar, a Rutgers plant scientist who is in charge of this effort.

The disease, called Eastern Filbert Blight, is caused by a fungus. Some relatives of the commercial hazelnut, native to North America, can withstand the fungus. But the European hazelnut, the kind that fetches high prices, cannot. When the fungus attacks, it ruptures the bark around each branch, and the tree dies.

About 10 years ago, though, a plant breeder at Rutgers named C. Reed Funk embarked on a quest for hazelnut trees that could survive Eastern Filbert Blight. Similar efforts have been underway at Oregon State University, because Eastern Filbert Blight has made its way to Oregon as well, threatening the orchards there.

"I personally went and made seed collections in Eastern Europe, Russia, Poland, Ukraine," says Molnar. "I collected thousands of seeds. We grew them as we normally would, and I'd say that 98 percent of them died."

The other 2 percent, though, did not. They carried genes that allowed them to survive the blight. Molnar cross-pollinated these blight-resistant trees with other hazelnut trees, from Oregon, that produce lots of high-quality nuts. He collected the offspring of that mating, looking for individual trees with the ideal genetic combination: blight resistance and big yields.

Molnar shows me a few candidate trees. They're thriving, and producing lots of nuts. Molnar and his colleagues now are conducting field trials of these trees in 10 locations around the Eastern U.S. and Canada to see whether they yield enough nuts to be commercially successful.

Molnar is optimistic. His efforts have even caught the attention of Ferrero, the Nutella-maker. "They've come here several times," Molnar says. "They've told me, if we can meet their quality specifications, they'd be interested in buying all the hazelnuts that we can produce."

If you just want to get one of these trees and grow hazelnuts in your backyard, though, Molnar does have a warning. "I haven't seen any other food that drives squirrels more crazy than hazelnuts," he says. Squirrels will do almost anything to get their greedy little paws on the nuts before you do.

So your hazelnuts may need a guard dog — one that likes to chase squirrels.

A new study from Denmark has indicated that a substantial proportion of farmers may place professional values above cost savings when making decisions about how much pesticide to use. This implies that agricultural policy should consider a broad array of policy instruments to reduce pesticide usage.

An extensive field investigation discovered that 38% of soils in southwest England show signs of enhanced surface water runoff due to soil degradation. The study also revealed which types of fields and soils are linked to the most or least degradation.

A recent survey of businesses in France, Germany and the UK has revealed that they recycle and refurbish much of their waste electrical and electronic equipment (WEEE). However, some of this information is not being reported under the EU’s WEEE Directive because the waste is being disposed of informally or by contractors, rather than by manufacturers who are responsible for the whole life cycle of the products.

Over a 20-year time period, the greenhouse gas (GHG) footprint of shale gas is greater than that of coal, oil or conventional gas, according to a recent study. Methane emissions make up most of this footprint. This suggests that substituting conventional fossil fuels with shale gas may not have the desired effect to mitigate climate warming in the short-term.

For thousands of years, vast amounts of methane – a potent greenhouse gas – have been stored in frozen deposits on land and under the ocean in the Arctic. A new study has found that rapidly rising temperatures are accelerating the release of methane by thawing subsea ‘permafrost’, releasing nearly 8 million tonnes into the atmosphere each year and potentially increasing global warming.

Scientists have found that retreating glaciers and melting permafrost in Alaska are releasing up to 70% more methane – a potent greenhouse gas – than previously thought. If this estimate is true for the rest of the Arctic, this could have serious implications for global warming, say the scientists.

Despite better public transport and more energy-efficient housing, city dwellers have a larger carbon footprint than those in rural areas, according to a recent Finnish study. This is partly explained by the phenomenon of ‘parallel consumption’ in which people extend their living space by using services that the home also provides.

The largest ice sheet in the world, the east Antarctic ice sheet, may succumb to climate change faster than thought, according to recent research. Warming ocean currents, triggered by shifting wind patterns, could accelerate melting of the ice sheet, leading to a rise in sea levels, say the researchers.

Over 75 000 regulatory inspection reports for over 32 000 oil and gas production wells drilled in Pennsylvania, US between 2000 and 2012, have been analysed in a recent study. In these reports, the inspectors logged six times as many incidents of damage to the walls of shale gas and oil wells than in wells for conventional oil and gas.

Higher temperatures being brought about by global warming are increasing methane emissions from the extensive northern European peatlands, a recent study has found. The researchers also say that future estimations of greenhouse gas emissions can be improved via better land-cover classification — i.e. determining how much peatland is fenland or bogland.

In the Mediterranean region the demand for natural resources and ecological services is two and half times greater than ecosystems’ capacity to provide them, recent research has found. To meet this demand, countries rely on imports, exposing themselves to price volatility and potential resource shortages. According to the authors, a 10% increase in global prices would particularly impact vulnerable countries such as Jordan, which would see its trade balance worsening by 2.4% of its gross domestic product.

US teens are more likely to vape for the flavourings found in e-cigarettes rather than nicotine, suggests research published online in the journal Tobacco Control.

TEvery kilometre travelled by car incurs costs to the individual and society that are more than six times those of travelling by bicycle, a new study suggests. The researchers presented a cost-benefit analysis developed for Copenhagen, finding that cars resulted in costs of 0.50 €/km in comparison to 0.08 €/km for bikes.

Firms that voluntarily adopt environmental policies appear to develop more innovative and proactive measures than firms where policies are imposed, according to new research. A study of 1151 Spanish firms indicated that those that self-regulate, especially in co-operation with other firms, seem to perform better environmentally.

When broken down, ships can release hazardous substances into the environment. This study investigated the environmental impact of shipbreaking in one of Europe’s few ship recycling yards, based in Portugal. The results reveal large differences between assessment methods and show that environmental impact depends on composition rather than size or class.

Increasing crop production to meet demand for biofuels potentially increases the use of nitrogen fertilisers, which can lead to nitrate pollution in surface and groundwater. A new study is the first to consider the unintended extra energy needed to treat water to remove nitrate contamination in drinking water supplies.

Shellfish harvesting areas in the UK are cleaner, thanks to sewerage improvement schemes over the last decade which have lowered average levels of Escherichia coli in oysters, mussels and other commercially-important species and boosted the shellfish industry’s economic value. Addressing the additional pollution risks from agriculture could further reduce contamination and human health risks.

Phosphorus in sewage and manure could be more available to crops than previously thought, suggests new research. The study found that some forms of sewage and manure treatment provided plants with more phosphorus than conventional inorganic fertilisers.

“We have attracted interest from companies such global giant Samsung and Chinese OEMs in the mobile phone segment coupled with the right set of incentives for them,” said Faisal Kawoosa, founder and chief analyst, TechArc. “The mass domestic market, which was underpenetrated for long, has provided an opportunity to these players to address local demand as well as set-up base here,” he added.

Using commercial seed mixtures to replant European grasslands tends to produce a smaller range of species than originally grew on the land. New research has identified several methods that successfully reproduce the original range of species, such as transferring of fresh hay or soil that contains seeds.

A proactive approach to biodiversity loss ??? where conservation of a species starts before it becomes endangered ??? could save millions of euros compared to the cost of recovering a population already in serious decline, according to new research.

One strategy to halt the loss of biodiversity has been to create protected areas in the sea and on land. However, a new study suggests that unless additional measures are taken, particularly those that tackle human population growth and the increased use of natural resources, even the development of new protected areas will be unable to reverse the trend of global biodiversity loss.

A new study suggests that improving the quality of existing wildlife habitat is more important than creating new habitat, when attempting to counteract the negative effects of climate change on species survival. This suggests that resources would be better directed towards habitat rehabilitation and reforestation than building new habitat features.

The litter size of the endangered European mink is less than half of that of its main competitor, the invasive American mink, research shows. The higher fertility of the American mink may allow rapid population growth of this species, threatening European mink with extinction.
