Participatory topological mapping: A novel approach for exploring and communicating situated knowledge of complex socio-ecological systems

Methodological Innovations, Ahead of Print. Land use change impacts on Sámi reindeer husbandry are well-documented, but existing maps often fail to capture socio-ecological relationships between herders, reindeer and nature. Conventional Geographic Information Systems (GIS) simplify these relationships, lacking local context and excluding valuable knowledge due to their rigid structure. This paper introduces participatory topological mapping, […]

AlphaFold-assisted structure determination of a bacterial protein of unknown function using X-ray and electron crystallography

Macromolecular crystallography generally requires the recovery of missing phase information from diffraction data to reconstruct an electron-density map of the crystallized molecule. Most recent structures have been solved using molecular replacement as a phasing method, requiring an a priori structure that is closely related to the target protein to serve as a search model; when no such search model exists, molecular replacement is not possible. New advances in computational machine-learning methods, however, have resulted in major advances in protein structure predictions from sequence information. Methods that generate predicted structural models of sufficient accuracy provide a powerful approach to molecular replacement. Taking advantage of these advances, AlphaFold predictions were applied to enable structure determination of a bacterial protein of unknown function (UniProtKB Q63NT7, NCBI locus BPSS0212) based on diffraction data that had evaded phasing attempts using MIR and anomalous scattering methods. Using both X-ray and micro-electron (microED) diffraction data, it was possible to solve the structure of the main fragment of the protein using a predicted model of that domain as a starting point. The use of predicted structural models importantly expands the promise of electron diffraction, where structure determination relies critically on molecular replacement.

New insights into the domain of unknown function (DUF) of EccC5, the pivotal ATPase providing the secretion driving force to the ESX-5 secretion system

Type VII secretion (T7S) systems, also referred to as ESAT-6 secretion (ESX) systems, are molecular machines that have gained great attention due to their implications in cell homeostasis and in host–pathogen interactions in mycobacteria. The latter include important human pathogens such as Mycobacterium tuberculosis (Mtb), the etiological cause of human tuberculosis, which constitutes a pandemic accounting for more than one million deaths every year. The ESX-5 system is exclusively found in slow-growing pathogenic mycobacteria, where it mediates the secretion of a large family of virulence factors: the PE and PPE proteins. The secretion driving force is provided by EccC5, a multidomain ATPase that operates using four globular cytosolic domains: an N-terminal domain of unknown function (EccC5DUF) and three FtsK/SpoIIIE ATPase domains. Recent structural and functional studies of ESX-3 and ESX-5 systems have revealed EccCDUF to be an ATPase-like fold domain with potential ATPase activity, the functionality of which is essential for secretion. Here, the crystal structure of the MtbEccC5DUF domain is reported at 2.05 Å resolution, which reveals a nucleotide-free structure with degenerated cis-acting and trans-acting elements involved in ATP binding and hydrolysis. This crystallographic study, together with a biophysical assessment of the interaction of MtbEccC5DUF with ATP/Mg2+, supports the absence of ATPase activity proposed for this domain. It is shown that this degeneration is also present in DUF domains from other ESX and ESX-like systems, which are likely to exhibit poor or null ATPase activity. Moreover, based on an in silico model of the N-terminal region of MtbEccC5DUF, it is hypothesized that MtbEccC5DUF is a degenerated ATPase domain that may have retained the ability to hexamerize. These observations draw attention to DUF domains as structural elements with potential implications in the opening and closure of the membrane pore during the secretion process via their involvement in inter-protomer interactions.

Comparison of two crystal polymorphs of NowGFP reveals a new conformational state trapped by crystal packing

Crystal polymorphism serves as a strategy to study the conformational flexibility of proteins. However, the relationship between protein crystal packing and protein conformation often remains elusive. In this study, two distinct crystal forms of a green fluorescent protein variant, NowGFP, are compared: a previously identified monoclinic form (space group C2) and a newly discovered ortho­rhombic form (space group P212121). Comparative analysis reveals that both crystal forms exhibit nearly identical linear assemblies of NowGFP molecules interconnected through similar crystal contacts. However, a notable difference lies in the stacking of these assemblies: parallel in the monoclinic form and perpendicular in the orthorhombic form. This distinct mode of stacking leads to different crystal contacts and induces structural alteration in one of the two molecules within the asymmetric unit of the orthorhombic crystal form. This new conformational state captured by orthorhombic crystal packing exhibits two unique features: a conformational shift of the β-barrel scaffold and a restriction of pH-dependent shifts of the key residue Lys61, which is crucial for the pH-dependent spectral shift of this protein. These findings demonstrate a clear connection between crystal packing and alternative conformational states of proteins, providing insights into how structural variations influence the function of fluorescent proteins.

Crystal structure and Hirshfeld surface analysis of 3,3'-[ethane-1,2-diylbis(­oxy)]bis­(5,5-di­methyl­cyclo­hex-2-en-1-one) including an unknown solvate

The title mol­ecule, C18H26O4, consists of two symmetrical halves related by the inversion centre at the mid-point of the central –C—C– bond. The hexene ring adopts an envelope conformation. In the crystal, the mol­ecules are connected into dimers by C—H⋯O hydrogen bonds with R22(8) ring motifs, forming zigzag ribbons along the b-axis direction. According to a Hirshfeld surface analysis, H⋯H (68.2%) and O⋯H/H⋯O (25.9%) inter­actions are the most significant contributors to the crystal packing. The contribution of some disordered solvent to the scattering was removed using the SQUEEZE routine [Spek (2015). Acta Cryst. C71, 9–18] in PLATON. The solvent contribution was not included in the reported mol­ecular weight and density.

Fast nanoscale imaging of strain in a multi-segment heterostructured nanowire with 2D Bragg ptychography

Developing semiconductor devices requires a fast and reliable source of strain information with high spatial resolution and strain sensitivity. This work investigates the strain in an axially heterostructured 180 nm-diameter GaInP nanowire with InP segments of varying lengths down to 9 nm, simultaneously probing both materials. Scanning X-ray diffraction (XRD) is compared with Bragg projection ptychography (BPP), a fast single-projection method. BPP offers a sufficient spatial resolution to reveal fine details within the largest segments, unlike scanning XRD. The spatial resolution affects the quantitative accuracy of the strain maps, where BPP shows much-improved agreement with an elastic 3D finite element model compared with scanning XRD. The sensitivity of BPP to small deviations from the Bragg condition is systematically investigated. The experimental confirmation of the model suggests that the large lattice mismatch of 1.52% is accommodated without defects.

Neural network analysis of neutron and X-ray reflectivity data incorporating prior knowledge

Due to the ambiguity related to the lack of phase information, determining the physical parameters of multilayer thin films from measured neutron and X-ray reflectivity curves is, on a fundamental level, an underdetermined inverse problem. This ambiguity poses limitations on standard neural networks, constraining the range and number of considered parameters in previous machine learning solutions. To overcome this challenge, a novel training procedure has been designed which incorporates dynamic prior boundaries for each physical parameter as additional inputs to the neural network. In this manner, the neural network can be trained simultaneously on all well-posed subintervals of a larger parameter space in which the inverse problem is underdetermined. During inference, users can flexibly input their own prior knowledge about the physical system to constrain the neural network prediction to distinct target subintervals in the parameter space. The effectiveness of the method is demonstrated in various scenarios, including multilayer structures with a box model parameterization and a physics-inspired special parameterization of the scattering length density profile for a multilayer structure. In contrast to previous methods, this approach scales favourably when increasing the complexity of the inverse problem, working properly even for a five-layer multilayer model and a periodic multilayer model with up to 17 open parameters.

Gay And Bisexual Men Are Now Allowed To Donate Blood In England, Scotland And Wales

Gay and bisexual men in England, Scotland, and Wales can now donate blood, plasma and platelets under certain circumstances without having to wait three months, the National Health Service announced this week.; Credit: Wilfredo Lee/AP

Jaclyn Diaz | NPR

Gay and bisexual men in England, Scotland, and Wales can now donate blood, plasma and platelets under certain circumstances, the National Health Service announced this week in a momentous shift in policy for most of the U.K.

Beginning Monday, gay men in sexually active, monogamous relationships for at least three months can donate for the first time. The move reverses a policy that limited donor eligibility on perceived risks of contracting HIV/AIDs and other sexually transmitted infections.

The new rules come as the U.K. and other countries around the world report urgent, pandemic-induced blood supply issues.

Donor eligibility will now be based on each person's individual circumstances surrounding health, travel and sexual behaviors regardless of gender, according to the NHS. Potential donors will no longer be asked if they are a man who has had sex with another man, but they will be asked about recent sexual activity.

Anyone who has had the same sexual partner for the last three months can donate, the NHS said.

"Patient safety is at the heart of everything we do. This change is about switching around how we assess the risk of exposure to a sexual infection, so it is more tailored to the individual," said Ella Poppitt, Chief Nurse for blood donation at NHS Blood and Transplant, in a statement. "We screen all donations for evidence of significant infections, which goes hand-in-hand with donor selection to maintain the safety of blood sent to hospitals."

People who engage in anal sex with a new partner or multiple people or who have recently used PrEP or PEP (medication used to prevent HIV infection) will have to wait three months to donate - regardless of their gender.

Why did the U.K. make this change?

The NHS moved to alter its blood donation eligibility rules following a review by the FAIR (For the Assessment of Individualised Risk) steering group. The panel determined an individualized, gender-neutral approach to determining who can donate blood, platelets, and plasma is fairer and still maintains the safety of the U.K.'s blood supply.

The findings were accepted in full by the government last December.

Researchers will continue to monitor the impact of the donor selection changes for the next 12 months to determine if more changes are needed, NHS said.

What is the policy in the U.S.?

Despite efforts by advocates to change regulations in the U.S, the ability for gay and bisexual men to donate blood is still restricted.

A ban on gay and bisexual blood donors has been in effect since the early 1980s when fears about HIV/AIDS were widespread.

The Food and Drug Administration's current policy states a man who has sex with another man in the previous three months can't donate. Federal rules previously made such donors wait 12 months before giving blood, but due to low blood supplies during the pandemic the federal government changed the policy in April.

The Red Cross said they are participating in a pilot study funded by the FDA using behavior-based health history questionnaires, similar to those used in the U.K.

Pfizer's COVID Vaccine In Teens And Myocarditis: What You Need To Know

A teen gets a dose of Pfizer's COVID-19 vaccine at Holtz Children's Hospital in Miami on May 18. Nearly 7 million U.S. teens and pre-teens (ages 12 through 17) have received at least one dose of a COVID-19 vaccine, so far, the CDC says.; Credit: Eva Marie Uzcategui/Bloomberg via Getty Images

Joanne Silberner | NPR

It's been a little more than a month since adolescents as young as 12 became eligible in the United States to receive the Pfizer vaccine against COVID-19, and nearly all reports have been positive: The vaccine is very effective in this age group, and the vast majority of kids experience mild side effects, if any — the same sore arm or mild flu-like symptoms seen among adults who get the shot.

The Centers for Disease Control and Prevention has recommended that everyone 12-years-old and older get vaccinated against COVID-19, and the rollout is well underway: According to the CDC, nearly 7 million U.S. teens and pre-teens (ages 12 through 17) have received at least one dose of a COVID-19 vaccine, so far.

Still, soon after the FDA authorized the use of Pfizer's vaccine in young people, federal agencies began receiving reports of mild chest pain or other signs of possible heart inflammation (known as myocarditis) in a very small percentage of recently vaccinated teens.

CDC director Rochelle Walensky said at a White House briefing Friday that there have been more than 300 cases of heart inflammation reported among more than 20 million teens and young adults who have received one of the vaccines made by Moderna or Pfizer. She said that in the "vast majority" of cases, the inflammation went away.

An expert advisory committee to the health agency is expected to review the cases in more depth at a meeting Friday.

So, in the meantime, should parents of teens hesitate to have their kids vaccinated against COVID-19? Vaccine experts and the American Academy of Pediatrics say no, don't hesitate. It's good for doctors and patients to be aware that there might be a connection between the mRNA vaccines and heart inflammation, and to report to their pediatrician anything they see in that first week after vaccination. But it is also important, the CDC notes, to recognize that even if this does turn out to be an extremely rare side effect of the vaccine, "most patients who received care responded well to medicine and rest and quickly felt better." And the serious risks of COVID -19 — even for young healthy people — outweigh the risks of any possible side effects from the vaccine. Here are some questions you may have, and what's known:

What exactly is myocarditis?

Myocarditis is an inflammation of the heart muscle, and pericarditis, also being investigated, is an inflammation of the sac around the heart.

Long before the pandemic, thousands of cases of myocarditis were diagnosed in the U.S. and around the world each year, often triggered by the body's immune response to infections. SARS-CoV-2 can trigger it, and so can cold viruses, and staph and strep and HIV. Other causes include toxins and allergies.

Symptoms include chest pain and shortness of breath. It's often mild enough to go unnoticed, but a full-blown case in adults can cause arrhythmias and heart failure that require careful treatment with multiple medications, and several months of strict rest. In a case study of seven teenagers who got myocarditis following vaccination published last week in the journal Pediatrics, all seven got better after routine treatment with anti-inflammatory drugs.

Pediatric cardiologist Dr. Stuart Berger of the Northwestern University Feinberg School of Medicine, a spokesperson for the American Academy of Pediatrics, says vaccine-related myocarditis in teens is not all that worrisome. "Although they appear with some symptoms of chest pain, and maybe some findings on EKGs, all of the cases we've seen have been on the mild end of the spectrum," he says.

So, what's the concern?

Several hundred reports about the inflammation have been filed with the federal government's Vaccine Adverse Event Reporting System (VAERS); that's a repository of reports sent in by health professionals and patients about any health events they spot in the hours or days after vaccinations. Many of the events reported turn out to be coincidental — not caused by a vaccine. The database is just meant as a starting point for further investigation and not proof of cause and effect. But as NPR's Geoff Brumfiel noted this week, "when millions of people are vaccinated within a short period, the total number of these reported events can look big."

That said, anecdotes reported by doctors in medical journals and reports to VAERS suggest that both of the mRNA vaccines authorized for use in the U.S. — the Pfizer and Moderna vaccines — might slightly increase the incidence of myocarditis in young people. In 2003, a report in the New England Journal of Medicine estimated the background incidence of myocarditis to be 1.13 cases in 100,000 children per year.

Paul Offit, professor of pediatrics at the Children's Hospital of Philadelphia and a member of a Food and Drug Administration vaccine advisory committee says there likely is a causal link between the heart inflammation some doctors are seeing in these teens and the second dose of vaccine. "I think it's real," he says, but hastens to add that the effect is exceedingly small – based on the data collected so far, maybe one in 50,000 vaccinees between the ages of 16 and 39. "And the good news is at least so far it looks to be transient and self-resolving."

Still, maybe I should wait to get my teen vaccinated and see how this plays out?

Uhm, no, according to several vaccine experts contacted by NPR. And this is where a little math comes in handy.

"Take a stadium full of 100,000 people between the ages of 16 and 39, which is the subset that appears to be at greater risk," Offit says. "Vaccinate all of them, and two might get myocarditis." But if you don't vaccinate any of the 100,000, he estimates that about 1,300 would eventually get COVID-19. And those numbers are likely to increase this winter.

About one in 1,000 children who get COVID-19 have gone on to develop a condition called MIS-C (multisystem inflammatory syndrome in children), says Offit, and most of those kids have had some level of myocarditis. In addition, the new coronavirus has directly caused myocarditis in some children and adults. Which of the two stadiums in Offit's metaphor would have more cases of myocarditis — the vaccinated children or unvaccinated kids — is not known precisely. But Offit says he suspects it would be the unvaccinated group. And there's no doubt that 1,000 unvaccinated children would suffer more COVID-19-related illnesses. "A choice not to get a vaccine is not a choice to avoid myocarditis," he says. "It's a choice to take a different risk — and I would argue a more serious one" — of developing a bad case of COVID-19 or long-COVID or COVID-caused myocarditis.

Are the experts advising their own kids in this age group to get vaccinated?

Yes. "I understand people having concerns," says Dr. Judith Guzman-Cottrill. She's a parent and professor of pediatric infectious diseases at the Oregon Health and Science University, as well as the senior author on a small study that came out this month in the journal Pediatrics. In the report, Guzman-Cottrill and her colleagues analyzed the cases of seven boys around the country who developed myocarditis within four days of receiving the Pfizer-BioNTech vaccine.

She and her family recently faced the vaccination decision for her own 13-year-old daughter — and said a whole-hearted yes to the shot.

Guzman-Cottrill suspects there may turn out to be a slightly increased risk of heart inflammation from vaccination in young people, but she and her co-authors note in the Pediatrics report that a direct cause-and-effect connection — even in these seven cases — has yet to be established. And she's impressed that despite the millions of doses that have so far been delivered to teens, no clear and serious post-vaccination problems have shown up. "The emergency departments and urgent care clinics are not filled with teenagers complaining of chest pain," she says.

She's treated unvaccinated teens who developed severe myocarditis from an infection with the COVID-19 virus, and others who developed COVID-19 pneumonia and respiratory failure. Seeing those teens struggle — teens who lacked the powerful immune protection the vaccine provides — was enough for her to suggest vaccination to her daughter, who got her second vaccination earlier this week.

"She saw it as a pathway back to a normal post pandemic life," Guzman-Cottrill says.

And that's where public health comes in. "We really need a highly vaccinated student body when kids return to the classroom this fall," says Guzman-Cottrill, "so we don't see surges in COVID-19 cases."

Despite the racial reckoning going on in America right now, and despite the fact that attitudes towards race, inclusion and representation are different now than they were 30 years ago, new research from UC Berkeley shows that a large majority of American metro areas are more segregated now than they were in 1990. The new report from Berkeley’s Institute covers a number of topic areas, but among the key findings were from the national segregation report component of the project, which found Los Angeles to be the sixth-most segregated metro area with more than 200,000 people.

Today on AirTalk, we’ll talk with the lead researcher on the new report and a local historian to talk about how we see the findings of the report play out in Southern California.
