BioStruct-Africa: empowering Africa-based scientists through structural biology knowledge transfer and mentoring – recent advances and future perspectives

Being able to visualize biology at the molecular level is essential for our understanding of the world. A structural biology approach reveals the molecular basis of disease processes and can guide the design of new drugs as well as aid in the optimization of existing medicines. However, due to the lack of a synchrotron light source, adequate infrastructure, skilled persons and incentives for scientists in addition to limited financial support, the majority of countries across the African continent do not conduct structural biology research. Nevertheless, with technological advances such as robotic protein crystallization and remote data collection capabilities offered by many synchrotron light sources, X-ray crystallography is now potentially accessible to Africa-based scientists. This leap in technology led to the establishment in 2017 of BioStruct-Africa, a non-profit organization (Swedish corporate ID: 802509-6689) whose core aim is capacity building for African students and researchers in the field of structural biology with a focus on prevalent diseases in the African continent. The team is mainly composed of, but not limited to, a group of structural biologists from the African diaspora. The members of BioStruct-Africa have taken up the mantle to serve as a catalyst in order to facilitate the information and technology transfer to those with the greatest desire and need within Africa. BioStruct-Africa achieves this by organizing workshops onsite at our partner universities and institutions based in Africa, followed by post-hoc online mentoring of participants to ensure sustainable capacity building. The workshops provide a theoretical background on protein crystallography, hands-on practical experience in protein crystallization, crystal harvesting and cryo-cooling, live remote data collection on a synchrotron beamline, but most importantly the links to drive further collaboration through research. Capacity building for Africa-based researchers in structural biology is crucial to win the fight against the neglected tropical diseases, e.g. ascariasis, hookworm, trichuriasis, lymphatic filariasis, active trachoma, loiasis, yellow fever, leprosy, rabies, sleeping sickness, onchocerciasis, schistosomiasis, etc., that constitute significant health, social and economic burdens to the continent. BioStruct-Africa aims to build local and national expertise that will have direct benefits for healthcare within the continent.

Synthesis and crystal structure of a mixed alkaline-earth powellite, Ca0.84Sr0.16MoO4

A mixed alkaline-earth powellite, Ca0.84Sr0.16MoO4 (calcium strontium molybdate), was synthesized by a flux method and its crystal structure was solved using single-crystal X-ray diffraction (SC-XRD) data. The compound crystallized in the I41/a space group as with a typical CaMoO4 powellite, but with larger unit-cell parameters and unit-cell volume as a result of the partial incorporation of larger Sr cations into the Ca sites within the crystal. The unit cell and volume were well fitted with the trendline calculated from literature values, and the powder X-ray diffraction (P-XRD) pattern of the ground crystal is in good agreement with the calculated pattern from the solved structure.

The predictive power of data-processing statistics

This study describes a method to estimate the likelihood of success in determining a macromolecular structure by X-ray crystallography and experimental single-wavelength anomalous dispersion (SAD) or multiple-wavelength anomalous dispersion (MAD) phasing based on initial data-processing statistics and sample crystal properties. Such a predictive tool can rapidly assess the usefulness of data and guide the collection of an optimal data set. The increase in data rates from modern macromolecular crystallography beamlines, together with a demand from users for real-time feedback, has led to pressure on computational resources and a need for smarter data handling. Statistical and machine-learning methods have been applied to construct a classifier that displays 95% accuracy for training and testing data sets compiled from 440 solved structures. Applying this classifier to new data achieved 79% accuracy. These scores already provide clear guidance as to the effective use of computing resources and offer a starting point for a personalized data-collection assistant.

Fast continuous measurement of synchrotron powder diffraction synchronized with controlling gas and vapour pressures at beamline BL02B2 of SPring-8

A gas- and vapour-pressure control system synchronized with the continuous data acquisition of millisecond high-resolution powder diffraction measurements was developed to study structural change processes in gas storage and reaction materials such as metal organic framework compounds, zeolite and layered double hydroxide. The apparatus, which can be set up on beamline BL02B2 at SPring-8, mainly comprises a pressure control system of gases and vapour, a gas cell for a capillary sample, and six one-dimensional solid-state (MYTHEN) detectors. The pressure control system can be remotely controlled via developed software connected to a diffraction measurement system and can be operated in the closed gas and vapour line system. By using the temperature-control system on the sample, high-resolution powder diffraction data can be obtained under gas and vapour pressures ranging from 1 Pa to 130 kPa in temperatures ranging from 30 to 1473 K. This system enables one to perform automatic and high-throughput in situ X-ray powder diffraction experiments even at extremely low pressures. Furthermore, this developed system is useful for studying crystal structures during the adsorption/desorption processes, as acquired by millisecond and continuous powder diffraction measurements. The acquisition of diffraction data can be synchronized with the control of the pressure with a high frame rate of up to 100 Hz. In situ and time-resolved powder diffraction measurements are demonstrated for nanoporous Cu coordination polymer in various gas and vapour atmospheres.

POWGEN: rebuild of a third-generation powder diffractometer at the Spallation Neutron Source

The neutron powder diffractometer POWGEN at the Spallation Neutron Source has recently (2017–2018) undergone an upgrade which resulted in an increased detector complement along with a full overhaul of the structural design of the instrument. The current instrument has a solid angular coverage of 1.2 steradians and maintains the original third-generation concept, providing a single-histogram data set over a wide d-spacing range and high resolution to access large unit cells, detailed structural refinements and in situ/operando measurements.

Neutron Larmor diffraction on powder samples

A hitherto unrecognized resolution effect in neutron Larmor diffraction (LD) is reported, resulting from small-angle neutron scattering (SANS) in the sample. Small distortions of the neutron trajectories by SANS give rise to a blurring of the Bragg angles of the order of a few hundredths of a degree, leading to a degradation of the momentum resolution. This effect is negligible for single crystals but may be significant for polycrystalline or powder samples. A procedure is presented to correct the LD data for the parasitic SANS. The latter is accurately determined by the SESANS technique (spin–echo small-angle neutron scattering), which is readily available on Larmor diffractometers. The analysis technique is demonstrated on LD and SESANS data from α-Fe2O3 powder samples. The resulting d-spacing range agrees with experimental data from high-resolution synchrotron radiation powder diffraction on the same sample.

R-rated Power Rangers fan film pulled from YouTube, but you can watch it here

A still from "POWER/RANGERS," a highly-produced Power Rangers fan film starring James Van Der Beek and Katee Sackhoff.

Mike Roe

Update 2/28: The "POWER/RANGERS" film is back on YouTube and Vimeo. Watch the censored YouTube version with a new viewer discretion disclaimer here:

POWER/RANGERS

You can also watch the Vimeo version, featuring more adult content. The video's description emphasizes its lack of connection in any official way to the Power Rangers:

"Deboot of the Power Rangers. My take on the FAN FILM. Not a pilot, not a series, not for profit, strictly for exhibition. This is a bootleg experiment not affiliated or endorsed by Saban Entertainment or Lionsgate nor is it selling any product. I claim no rights to any of the characters (don't send me any money, not kickstarted, this film is free). This is the NSFW version. An alternate safe version is on youtube."

Director Joseph Kahn tells Deadline, "They put these disclaimers on so kids so don’t confuse our super-violent film with their Power Rangers brand. There are no hard feelings. We signed contracts. We can play it anywhere we want on all platforms. I think they realized that people just want to see it."

Previously: A Power Rangers short film went viral this week, starring Katee Sackhoff (Battlestar Galactica) and James Van Der Beek (Dawson!) in a Tarantino-meets-sci-fi take on a dark future for the formerly Mighty Morphin'.

The company behind the 22-year history of the kids/toy icons issued takedown requests, leading to it being pulled from Vimeo and, on Thursday afternoon, a toned-down version being taken off YouTube. At the time, the video had received over 10 million views. It's still available to watch in this Facebook embed from the producer's Facebook page:

POWER/RANGERS Facebook embed

The film was directed by Joseph Kahn, best known as the music video director behind clips like Taylor Swift's "Blank Space" as well as videos for Britney Spears, U2 and others, and produced by Adi Shankar, who was also behind "The Grey" and "Dredd." Kahn co-wrote the film with Van Der Beek and lesser-known writer Dutch Southern.

This isn't the first quasi-legal fan film produced by Shankar. He's also done the same with Marvel Comics characters the Punisher and Venom. The Punisher film even had one of the actors who played the character on screen, Thomas Jane.

Watch those films (Warning: Adult language and violence):

Punisher short

Venom short

Kahn tells HitFix that Shankar came to him, offering him the chance to reboot an existing property.

One reason for the current legal contentiousness: The Power Rangers are set to hit the big screen next year in a Lionsgate film. Kahn says that, if that film was offered to him, he wouldn't be interested.

"I wouldn't even want to make 'Power Rangers: The Movie' for real," Kahn told HitFix. "Like if I had to make a 'Power Rangers' movie, this is it. It's 14 minutes long, and it's violent, and this is what I have in me. If they offered me the $200 million version, the PG-13 version, I literally wouldn't do it."

There's been a strong response to the video, but the response has been mixed — among the original Power Rangers. The original Green Ranger, actor Jason David Frank, said on Facebook that he was approached to be in the movie but declined. (The film's director denies this claim, saying that Frank must have confused them with another project.) Frank also criticized the adult content.

"I'm just a PG-13 guy," Frank said. "The cuss words, the drugs, all this other stuff, it doesn't fly with me." He says that he thinks the Power Rangers are still connected with kids, and he didn't like the idea of doing a dark and gritty version in that context. (Watch his video below.)

But the original Pink Ranger, actress Amy Jo Johnson, gave the film her stamp of approval, which Sackhoff enthusiastically responded to.

Katee Sackhoff tweet

Sackhoff told the Nerdcore Movement site that she loves fan films.

"Doing a fan video is kind of the biggest honor you can give a franchise. It’s something that inspired you so much that you want to create," Sackhoff said.

Kahn defended "POWER/RANGERS" on Twitter as being protected due to it being a satire and also cited fair use laws and free speech. He argued that there are lots of other fan films and pointed out that YouTube showed more leniency, leaving it up.

"Every image in POWER/RANGERS is original footage," Kahn wrote in a series of tweets to Vimeo. "Nothing was pre-existing. There is no copyrighted footage in the short."

He also said that it's being given away for free and that Kahn paid for it himself.

Kahn tweet

"It is just as if I drew a pic of Power Rangers on a napkin and I gave it to my friend," Kahn wrote. "Is it illegal to give pic I drew of a character on a napkin to someone for free? No. The world is watching your actions right now."

In a touch of irony, the video had been selected as a Vimeo staff pick before the service took it down. They also responded to complaints about it being taken down, saying that they had to due to the Digital Millennium Copyright Act, and that they would restore the video immediately if the copyright claim was withdrawn, telling fans to complain to Power Rangers copyright holder Saban.

YouTube tweet

Despite the short film's success, hardcore Power Rangers fans are less sure about it, Shamus Kelley tells KPCC. Kelley created his own Rangers fan series, as well as co-hosting a Power Rangers podcast with over 300 episodes so far.

Casual fans are "far more open to the idea of dark/gritty because they see it as the show growing up with them," Kelley says. To hardcore fans, "it was either an abomination or the greatest unintended parody ever."

Kahn tells HitFix that the parody, of both Power Rangers and fan films in general, is definitely intended.

"The dark and gritty reboot thing is such a cliché that the intention was not only to make it dark and gritty but make it even darker and grittier than you could possibly imagine, hence the brains, the blood and the violence and the sex," Kahn said.

Kahn is set to answer questions about the film in a Reddit AMA on Friday at 2 p.m. We'll have to wait and see if there will be anywhere to watch it at the time.
