Microcrystal electron diffraction (MicroED) combines crystallography and electron cryo-microscopy (cryo-EM) into a method that is applicable to high-resolution structure determination. In MicroED, nanosized crystals, which are often intractable using other techniques, are probed by high-energy electrons in a transmission electron microscope. Diffraction data are recorded by a camera in movie mode: the nanocrystal is continuously rotated in the beam, thus creating a sequence of frames that constitute a movie with respect to the rotation angle. Until now, diffraction-optimized cameras have mostly been used for MicroED. Here, the use of a direct electron detector that was designed for imaging is reported. It is demonstrated that data can be collected more rapidly using the Falcon III for MicroED and with markedly lower exposure than has previously been reported. The Falcon III was operated at 40 frames per second and complete data sets reaching atomic resolution were recorded in minutes. The resulting density maps to 2.1 Å resolution of the serine protease proteinase K showed no visible signs of radiation damage. It is thus demonstrated that dedicated diffraction-optimized detectors are not required for MicroED, as shown by the fact that the very same cameras that are used for imaging applications in electron microscopy, such as single-particle cryo-EM, can also be used effectively for diffraction measurements.

In the past three years, Dirac half-metals (DHMs) have attracted considerable attention and become a high-profile topic in spintronics becuase of their excellent physical properties such as 100% spin polarization and massless Dirac fermions. Two-dimensional DHMs proposed recently have not yet been experimentally synthesized and thus remain theoretical. As a result, their characteristics cannot be experimentally confirmed. In addition, many theoretically predicted Dirac materials have only a single cone, resulting in a nonlinear electromagnetic response with insufficient intensity and inadequate transport carrier efficiency near the Fermi level. Therefore, after several attempts, we have focused on a novel class of DHMs with multiple Dirac crossings to address the above limitations. In particular, we direct our attention to three-dimensional bulk materials. In this study, the discovery via first principles of an experimentally synthesized DHM LaNiO3 with many Dirac cones and complete spin polarization near the Fermi level is reported. It is also shown that the crystal structures of these materials are strongly correlated with their physical properties. The results indicate that many rhombohedral materials with the general formula LnNiO3 (Ln = La, Ce, Nd, Pm, Gd, Tb, Dy, Ho, Er, Lu) in the space group R3c are potential DHMs with multiple Dirac cones.

Direct electron detectors (DEDs) have revolutionized cryo-electron microscopy (cryo-EM) by facilitating the correction of beam-induced motion and radiation damage, and also by providing high-resolution image capture. A new-generation DED, the DE64, has been developed by Direct Electron that has good performance in both integrating and counting modes. The camera has been characterized in both modes in terms of image quality, throughput and resolution of cryo-EM reconstructions. The modulation transfer function, noise power spectrum and detective quantum efficiency (DQE) were determined for both modes, as well as the number of images per unit time. Although the DQE for counting mode was superior to that for integrating mode, the data-collection throughput for this mode was more than ten times slower. Since throughput and resolution are related in single-particle cryo-EM, data for apoferritin were collected and reconstructed using integrating mode, integrating mode in conjunction with a Volta phase plate (VPP) and counting mode. Only the counting-mode data resulted in a better than 3 Å resolution reconstruction with similar numbers of particles, and this increased performance could not be compensated for by the increased throughput of integrating mode or by the increased low-frequency contrast of integrating mode with the VPP. These data show that the superior image quality provided by counting mode is more important for high-resolution cryo-EM reconstructions than the superior throughput of integrating mode.

The bacterial flavin adenine dinucleotide (FAD)-dependent glucose dehydrogenase complex derived from Burkholderia cepacia (BcGDH) is a representative molecule of direct electron transfer-type FAD-dependent dehydrogenase complexes. In this study, the X-ray structure of BcGDHγα, the catalytic subunit (α-subunit) of BcGDH complexed with a hitchhiker protein (γ-subunit), was determined. The most prominent feature of this enzyme is the presence of the 3Fe–4S cluster, which is located at the surface of the catalytic subunit and functions in intramolecular and intermolecular electron transfer from FAD to the electron-transfer subunit. The structure of the complex revealed that these two molecules are connected through disulfide bonds and hydrophobic interactions, and that the formation of disulfide bonds is required to stabilize the catalytic subunit. The structure of the complex revealed the putative position of the electron-transfer subunit. A comparison of the structures of BcGDHγα and membrane-bound fumarate reductases suggested that the whole BcGDH complex, which also includes the membrane-bound β-subunit containing three heme c moieties, may form a similar overall structure to fumarate reductases, thus accomplishing effective electron transfer.

Noncrystallographic symmetry (NCS) averaging following molecular-replacement phasing is generally the major technique used to solve a structure with several molecules in one asymmetric unit, such as a spherical icosahedral viral particle. As an alternative method to NCS averaging, a new approach to optimize or to refine the electron density directly under NCS constraints is proposed. This method has the same effect as the conventional NCS-averaging method but does not include the process of Fourier synthesis to generate the electron density from amplitudes and the corresponding phases. It has great merit for the solution of structures with limited data that are either twinned or incomplete at low resolution. This method was applied to the case of the T = 1 shell-domain subviral particle of Penaeus vannamei nodavirus with data affected by twinning using the REFMAC5 refinement software.

The standard method of joint probability distribution functions, so crucial for the development of direct methods, has been revisited and updated. It consists of three steps: identification of the reflections which may contribute to the estimation of a given structure invariant or seminvariant, calculation of the corresponding joint probability distribution, and derivation of the conditional distribution of the invariant or seminvariant phase given the values of some diffracted amplitudes. In this article the conditional distributions are derived directly without passing through the second step. A good feature of direct methods is that they may work in the absence of any prior information: that is also their weakness. Different types of prior information have been taken into consideration: interatomic distances, interatomic vectors, Patterson peaks, structural model. The method of directly deriving the conditional distributions has been applied to those cases. Some new formulas have been obtained estimating two-, three- and four-phase invariants. Special attention has been dedicated to the practical aspects of the new formulas, in order to simplify their possible use in direct phasing procedures.

I am pleased that the White House is moving to fill the position of director of the Office of Science and Technology Policy.

To answer significant questions about planetary systems, such as whether our solar system is a rare phenomenon or if life exists on planets other than Earth, NASA should lead a large direct imaging mission – an advanced space telescope – capable of studying Earth-like exoplanets orbiting stars similar to the sun, says a new congressionally mandated report by the National Academies of Sciences, Engineering, and Medicine.

Sethuraman “Panch” Panchanathan, executive vice president and chief research and innovation officer at Arizona State University (ASU), and ASU’s named representative to the National Academies’ Government-University-Industry-Research Roundtable (GUIRR), has been nominated by President Trump to serve as the next director of the National Science Foundation.

Monday's fat stack of news also includes some views about what to do about drought and Western water supplies.

The New York Times has published six answers to the questions "What are the best ways to share the water? And how can we ensure it lasts for the foreseeable future?" Pat Mulroy, former general manager of the Southern Nevada Water Authority, weighs in, as do several other think tankers:

[N]ew energy and fuel production options have become more water intensive. Unconventional oil and gas production methods such as hydraulic fracturing have significant implications for local and regional water quality and quantity. Bioenergy consumes water at various stages of production (including irrigation for crops) and also has impacts on water quality and quantity...We should be pursuing cleaner energy and streamlined approaches to conserving water in order to truly safeguard our water supply. (Newsha Ajami/Stanford University)

An incredible 40 percent of the water consumed by Americans goes into meat and dairy production. Livestock must drink water and there is some water use at the farm, but most of this water is for the producing animal feed...Is this a wise allocation of the limited supply of freshwater in America? (Arjen Hoekstra/University of Twente, Netherlands)

• Closer to home, the Sacramento Bee has an ongoing series about drought solutions. Mariposa County resident Tom DeVries, who lives in forestland at 4,000 feet, offers his take:

Trees take water; a big one can draw 100 gallons a day out of the ground. All that junk forest in California is sucking up water that should be filling my spring and well and flowing downhill toward the rest of you. (Sac Bee)

• You know who else has good ideas about how to conserve water in drought? Australians. (KQED)
• Jay Lund from UC Davis modeled a "mega-drought" with his team and found that the economic consequences of a big drought event could be mostly managed through smarter water conservation policies. (California Water Blog)
• Falling water levels at Lake Mead are lowering Hoover Dam's energy production. Generating units have recently been "derated," meaning that they're expected to have a lower capacity for producing electricity now that there's less water to turn turbines. (EE News)
• Jason Dearen and Garance Burke report on "senior rights holders," and how poorly California accounts for water use by people who have rights dating back before 1914 at anytime, and how much that matters now during the drought. (AP)
• You're gonna see a lot of these stories all week: it's a terrible year for setting off fireworks. I bet rural fire chiefs have their teeth on edge already. (Merced Sun-Star)
• And we'll finish up in Southern California. In the first of a duo of Dana Bartholomew stories, the Daily News reports on Turf Terminators, a company that offers to leverage the recently-raised turf removal incentive and swap out homeowners' lawns for less thirsty landscapes...essentially for free, since the company's premise is that it can do the work for the price of the rebate. (Daily News)
• In the second, Bartholomew profiles a Studio City water-conservation demonstration at homes along Rhodes Avenue. (Daily News)
• And a UCLA project examining water use and conservation potential in territory served by the Los Angeles Department of Water and Power suggests that we're not pricing water well enough to encourage conservation. Authors of a policy brief with the California Center for Sustainable Communities say dual metering, for inside and outside, would also improve conservation. (Imperial Valley News)

Washing your car with a garden hose can use up to 120 gallons of water. Most corner conveyor belt operations use less, but all that water can add up, as we told you in August.

That’s why the group LA Waterkeeper is challenging motorists to drive dirty and pledge to skip car washes for 60 days. 

"Water conservation is the easiest and most affordable way to quickly reduce water demand and also extend supplies into next year," says Liz Crosson, the group's executive director. 

This summer Ventura County’s water agency asked people to skip washing their rides for a month; some people got detailing and car washes as a reward. Crosson’s group is hoping bragging rights will be enough of an incentive. (Though there are some as-yet-undisclosed prizes.)

People who live in LA are really excited and interested by the cars that they drive," Crosson says. "And frankly, you can have a dirty car and you can have a sticker and have an excuse for having a dirty car so it saves your image too."

The campaign’s just kicking off this weekend (at the Abbott-Kinney festival), but Crosson’s already optimistic for success. Early adopters of the pledge are hundreds of people from the online site Reddit and the general manager for the Los Angeles Department of Water and Power.

Director Eliza Hittman on the set of her film "Never Rarely Sometimes Always".
; Credit: Focus Features/Never Rarely Sometimes Always (2020)

The film “Never Rarely Sometimes Always” was slated for a theatrical release in March, but due to COVID-19 screenings were postponed. Instead, the film is out on digital this week, currently sporting a 98 percent rating on Rotten Tomatoes and receiving critical acclaim both here on FilmWeek and nationwide as one of the best films of 2020 so far.

Writer-director Eliza Hittman’s third feature-length film is about two teenage girls Skylar (Talia Ryder) and Autumn (Sidney Flanagan) from rural Pennsylvania who travel to New York City for medical help after an unplanned pregnancy. Hittman says the idea for the film came to her when she read in a book about how some women in Ireland, which up until recently had very strict laws against abortions, would travel from Ireland to London in 24 hours just to get a procedure. It struck her as worthy of a screenplay, and the idea was born. As part of her research for the film Hittman went to a small coal-mining community in rural Pennsylvania and, even though she wasn’t pregnant, visited pregnancy centers, got tested, and talked with women getting treatment and counseling so she could, as she says, “write the scenes with credibility.”

Today on FilmWeek, we’ll air “The Frame” host John Horn’s interview with “Never Rarely Sometimes Always” director Eliza Hittman where the two discuss how Hittman came up with the idea for the film, her journey to rural America to find out what visiting pregnancy centers there is like, and how that informed the way she conceived and wrote the film.

Brad Bird has made a name for himself as the director of new age, animated classics, like “The Iron Giant” and “The Incredibles”. Now he’s teaming up with Turner Classic Movies to share his picks for classic movie watching that will keep you busy and entertained while you’re stuck at home.

Bird has curated a list of his favorite films which will air on this season’s “The Essentials” with TCM Primetime host Ben Mankiewicz. Every Saturday from May up to January of next year, TCM will air one of twenty movies chosen by Bird. His list includes big-name classics that any movie buff will recognize, like “Casablanca” and “Dr. Strangelove”. But Bird throws in a few surprises, one being that there are no animated films on his list. Another surprising thing viewers will notice is that about a third of the films included are musicals, like “Singin’ In The Rain” and “Guys And Dolls”. With TCM’s seemingly infinite library of movie classics to choose from, Bird says narrowing it down to only twenty favorites was a challenge. According to Bird, his list comprises movies that are not only entertaining but “transcend time” and “speak in a language that is still in many ways current”.

“The Essentials” was filmed in early December, but Bird’s list is coming out during a time when movie-going is looking very different these days. The virus has put the entire film industry on pause, with studios halting production and theaters closing their doors indefinitely. In lieu of new movie releases and regular theater-going, many are taking the opportunity to revisit the classics and Bird’s list provides a starting guide for which ones should be on your watch-list.

Today on FilmWeek, Brad Bird joins us to talk about his favorite movies, what projects he has lined up, and his thoughts on how the film industry is adjusting to and getting through the pandemic.

TCM’s “The Essentials” will air on Saturdays at 8 p.m. beginning May 2. For the full list and schedule of films, click here.

Two months is a long time to be quarantined in one place. Just ask, well, pretty much anyone in the era of COVID-19. But imagine if you were quarantined for two years instead of two months, all in the name of science, and it was by choice!

In 1991, eight researchers did exactly that in Oracle, Arizona as part of a first-of-its-kind mission called BIOSPHERE 2. No, there was no failed BIOSPHERE 1 mission -- BIOSPHERE 1 is planet Earth. The mission’s goal was to create a living ecosystem inside a massive glass and steel facility to show that human life could be sustained in outer space. The idea was that whenever humanity finally did gain the ability to travel deeper into space and colonize another planet, a biosphere would need to be built first so that life could be sustained. But what started as a science experiment quickly evolved into a cultural phenomenon, and while some watched with bated breath to see whether the researchers could really create a living ecosystem in a controlled environment, others saw the project and those who were involved as a cult of sorts. Director Matt Wolf explores BIOSPHERE 2  the researchers (“biospherians”) who carried the mission out, what ultimately happened and the good and bad ways in which it became a cultural phenomenon.

Today on FilmWeek, “The Frame” host John Horn talks with Wolf about the making of the film and what can be learned from the biospherians about our current situation staying at home because of COVID-19.

SmileDirectClub Inc. (SDC:NASDAQ) today announced "it has been issued a patent for its SmileShop intellectual property from the U.S. Patent & Trademark Office which further strengthens the telehealth dentistry pioneer's efforts to bring affordable, accessible oral care to more people through its unique and innovative teledentistry platform and direct-to-consumer business model." The firm claimed that the patent will prevent other clear aligner competitors from duplicating its business model for the next 18 years.

The company's CEO David Katzman commented, "This patent designation is a significant validation of our unique customer-oriented care model, and expands our category ownership, including the manufacturing and retail experience...As the industry pioneer and inventor of the SmileShop concept, this patent is recognition that SmileDirectClub offers an innovative way for consumers to access oral care that is safe, doctor-directed and convenient. We look forward to welcoming customers back to our SmileShops at the earliest and safest possible time."

"We are focused on the entire teeth straightening and care process, and we now own the manufacturing process of our clear aligner products, the customer experience via our teledentistry platform, as well as the retail experience for clear aligner therapy. This patent is another step in our process as we continue to grow and protect our business," Katzman added.

The firm advised that "the patent encompasses the unique SmileShop concept and process" which includes appointment scheduling, conducting an intraoral scan, generating an approved treatment plan by a licensed dentist or orthodontist and then creating and shipping the aligners to the customer. The company noted that so far more than one million customers have used its clear aligner therapy platform.

The company stated that it is planning to slowly reopen its SmileShops in the U.S. and other markets starting in May as local governments begin to lift business restrictions. The firm indicated that it will be supplying all of its SmileShop team members with face shields and other PPE and will institute staggered appointment times, temperature scans and other social distancing and sanitary measures to provide a safe experience for all staff and customers.

SmileDirectClub is an oral care company headquartered in Nashville, Tenn. The firm stated that it is the creator of the first direct-to-consumer medtech platform for teeth straightening. The company has since expanded its business and now offers its products directly through dentist and orthodontists' offices. Some of the products offered by the company include aligners, impression kits, retainers and whitening gel. In addition to the U.S., the company also operates in Australia, Canada, Germany, Hong Kong, Ireland, New Zealand and the U.K.

SmileDirectClub began the day with a market capitalization of around $2.1 billion with approximately 385 million shares outstanding and a short interest of about 10.4%. SDC shares opened more than 26% higher today at $6.76 (+$1.37, +26.42%) over yesterday's $5.39 closing price. The stock has traded today between $6.13 to $6.80 per share and is currently trading at $6.64 (+$1.25, +23.14%).

Two tagged Cuvier's beaked whales have shown intense and lasting avoidance behaviours in response to military sonar. In the first study of this kind, the whales showed significant responses to sonar at volumes that are currently assumed in the US to have no effect on behaviour.

A method has been developed to compare how EU Member States have implemented the Energy Performance Buildings Directive. It suggests that implementation varies widely across Europe but that the Czech Republic, Finland, Portugal and Slovakia have kept to the Directive’s aims and guidelines most closely, based on data available in 2009.

An overview of research into ‘nudge’ theory and practices has recently been presented. While there is much evidence to show how humans make decisions, translating these psychological and economic insights into viable policy instruments that encourage behavioural change remains challenging, the authors conclude.

The European Directive on the assessment and management of flood risks1 (the Floods Directive) represents a shift towards holistic and catchment-oriented management of flood risk and is likely to prompt changes to policy in many Member States. New research from Germany suggests that effective implementation of the Floods Directive is likely to be greatly aided by the participation of stakeholders and communication between groups.

New research has analysed some of the issues around the implementation of the EU's Environmental Noise Directive (END) by Member States. It demonstrated large differences in the way noise levels are calculated and geographically mapped between countries and called for more standardised and clearer guidelines.

New research has reviewed the Irish implementation of the first phase of the EU Noise Directive. So far 31 different organisations have been involved and this will increase throughout the second phase of the Directive's implementation. More standardisation is needed to harmonise activities, perhaps by establishing a national expert steering group.

The price of electrical and electronic equipment has risen by an average of 2.19% since the implementation of the Waste from Electrical and Electronic Equipment (WEEE) Directive, new research suggests. Researchers investigated products across 27 EU Member States, with the increases in price reflecting the fact that the consumer is bearing at least part of the cost of e-waste disposal.

Amid the covid 19 crisis, the Global Inhouse Centre of Canadian financial services company, Sun Life Financial Asia Service Centre India, is baselining projects that can be accelerated, re-scoped and deferred.

Flood prevention actions can redirect flooding to another location. A new French survey indicates that current local compensation policies to deal with this situation may be financially unviable. It suggests more practical solutions would involve insurance schemes and state intervention, as well as local water management institutions.

Ten years ago the European Water Framework Directive (WFD) introduced a shift in water management, placing ecology at the centre of decision-making. A new review of its implementation identifies both the achievements of the WFD and its ongoing challenges, providing recommendations on how to overcome these.

The importance of addressing eutrophication to improve the ecological health of coastal and marine waters has been identified in the EU Marine Strategy Framework Directive1. A new study discusses possible methods for assessing and monitoring eutrophication, including which indicators to monitor.

For successful implementation of the Water Framework Directive, local planners will need specific targets, guidance on interpretation, and adequate resources to monitor progress, according to a recent study from Sweden.

Improvements to EU water policy have been proposed in a recent study, to help ensure that temporary rivers and streams in the Mediterranean are adequately protected in line with the goals of the Water Framework Directive (WFD). The researchers suggest new classifications for river types, and highlight the importance of distinguishing between natural and human-derived causes of intermittent water flow.

A recent study has analysed research on implementing the Water Framework Directive (WFD) in Europe and identified a number of research gaps that could be filled. For example, some countries, such as Hungary, Romania and Slovakia, have not been well studied and more research on the experiences of such countries would build up knowledge on the implementation of the WFD across Europe.

Researchers have developed a new model to estimate the impact of harvesting wild species and land use change on biodiversity. Unlike previous models, it considers the indirect effect of harvesting or pest control on landscape structure through reducing the variety of species.

Bumblebees are negatively affected by the insecticide azadirachtin even at concentrations 50 times lower than the recommended levels used by farmers, recent laboratory experiments have revealed. No males hatched in laboratory colonies that were fed on recommended levels of the pesticide and, even at concentrations 50 times lower, the males that did hatch were deformed, and there were significantly fewer compared to an untreated colony.
