Frontotemporal dementia and parkinsonism (FTDP-17) caused by the 10+16 splice-site mutation in the MAPT provides an established platform to model tau-related dementia in vitro. Human iPSC-derived neurons have been shown to recapitulate the neurodevelopmental profile of tau pathology during in vitro corticogenesis as in the adult human brain. However, the neurophysiological phenotype of these cells has remained unknown, leaving unanswered questions over the functional relevance and the gnostic power of this disease model. Here we used electrophysiology to explore the membrane properties and intrinsic excitability of the generated neurons to find that human cells mature by ~150 days of neurogenesis to become compatible with matured cortical neurons. In earlier FTDP-17, neurons, however, exhibited a depolarized resting membrane potential associated with increased resistance and reduced voltage-gated Na⁺- and K⁺-channel-mediated conductance. The Na_v1.6 protein was reduced in FTDP-17. These led to a reduced cell capability of induced firing and changed action potential waveform in FTDP-17. The revealed neuropathology may thus contribute to the clinicopathological profile of the disease. This sheds new light on the significance of human models of dementia in vitro.

The positional change of nitro­gen-7 of the RNA constituent guanosine to the bridgehead position-5 leads to the base-modified nucleoside 5-aza-7-de­aza­guanosine. Contrary to guanosine, this mol­ecule cannot form Hoogsteen base pairs and the Watson–Crick proton donor site N3—H becomes a proton-acceptor site. This causes changes in nucleobase recognition in nucleic acids and has been used to construct stable `all-purine' DNA and DNA with silver-mediated base pairs. The present work reports the single-crystal X-ray structure of 7-iodo-5-aza-7-de­aza­guanosine, C10H12IN5O5 (1). The iodinated nucleoside shows an anti conformation at the glycosylic bond and an N conformation (O4'-endo) for the ribose moiety, with an anti­periplanar orientation of the 5'-hy­droxy group. Crystal packing is controlled by inter­actions between nucleobase and sugar moieties. The 7-iodo substituent forms a contact to oxygen-2' of the ribose moiety. Self-pairing of the nucleobases does not take place. A Hirshfeld surface analysis of 1 highlights the contacts of the nucleobase and sugar moiety (O—H⋯O and N—H⋯O). The concept of pK-value differences to evaluate base-pair stability was applied to purine–purine base pairing and stable base pairs were predicted for the construction of `all-purine' RNA. Furthermore, the 7-iodo substituent of 1 was functionalized with benzo­furan to detect motional constraints by fluorescence spectroscopy.

Oil and gas technology services and solutions company ION Geophysical Corp. (IO:NYSE) yesterday afternoon announced financial results for Q1/20 ending March 31, 2020.

The firm reported total net revenues of $56.4 million in Q1/20, which represented a 53% increase over $37.0 million in Q1/19. The company advised that the increase was due primarily to an increase in 2D multi-client data library sales.

For Q1/20, the firm additionally reported operating income of $6.3 million, compared to an operating loss of $15.9 million in Q1/19. The company further indicated that in Q1/20, it posted a net loss of $2.3 million, or ($0.16) per share, compared to a net loss of $21.4 million, or ($1.52) per share in Q1/19.

The company's President and CEO Chris Usher commented, "We achieved the best first quarter performance in six years despite challenges from both coronavirus and oil price volatility...Our strong revenues of $56 million generated positive operating income and $23 million in Adjusted EBITDA, and, as a result, we expect our liquidity position to improve as revenues are collected in the second quarter. Our first quarter results reflect the value of our offshore data library and validate the combined effectiveness of our strategic refocus and over $20 million cost reductions. Our team creatively closed a number of large multi-client contracts, some of which were delayed from the fourth quarter, even after E&P market dynamics changed. I remain confident in ION's value proposition to cost-effectively support customers' data-driven decision-making in this lower-for-longer exploration and production environment."

The company indicated that it has maintained a strong liquidity position in the face of energy market turmoil and the COVID-19 situation. The firm stated that as of March 31, 2020, it had total liquidity of $53.8 million, which consisted of $42.7 million in cash and $11.1 million remaining available balance under its $50.0 million revolving credit line.

ION Geophysical Corp. is a technology-focused company headquartered in Houston, Tex. that provides geophysical technology, services and solutions to the global oil and gas industry.

Rates of physical and sexual abuse of children have declined over the last 20 years, but for reasons not fully understood, says a new report from the Institute of Medicine. Yet, reports of psychological and emotional child abuse have risen in the same period, and data vary significantly as to whether child neglect is increasing, decreasing, or remaining constant.

While scientists have made remarkable advancements in astronomy and astrophysics since the beginning of this decade – notably the first detection of gravitational waves and the discovery of distant Earth-like planets – unforeseen constraints have slowed progress toward reaching some of the priorities and goals outlined in the Academies’ 2010 decadal survey of these disciplines, says a new report from the National Academies of Sciences, Engineering, and Medicine.

NASA, NSF, and NOAA have made substantial progress in implementing the programs recommended in the 2013 decadal survey on solar and space physics (heliophysics) despite a challenging budgetary landscape, says a new midterm assessment from the National Academies of Sciences, Engineering, and Medicine.

As of Monday afternoon, L.A. County has at least 1,260 deaths and 26,238 confirmed cases of coronavirus. The United States has more than a million cases of the virus with more than 67,000 deaths. Meanwhile, new models put together by FEMA project that we could see up to 200,000 new cases a day by the end of the month, according to the New York Times. 

The L.A. Times reports that scientists have discovered a new strain of the deadly coronavirus that is even more contagious. The study finds that the new strain first appeared in February in Europe and has been the dominant strain across the world since mid-March. Plus, some COVID-19 patients are experiencing issues with blood clotting even after respiratory issues have died down.

In the aftermath of natural disasters, displaced communities require temporary accommodation. A new study has examined how the built environment of these temporary communities influences their recovery and resilience, using accommodation set up after Hurricane Katrina as a case study. It highlights the importance of developing transitional built environments that consider the social and mental health needs of a community.

New research in Spain has explored solutions to reducing traffic noise, and suggests that the best option is to combine global measures, such as speed restrictions, and local measures, such as noise screens.

A new UK study suggests that there are associations between obesity, physical activity, and levels of CO2 emissions from transport. These associations seem mostly to reflect the fact that obese people tend to travel longer distances by motorised forms of travel. They may also partly reflect less ‘active travel’ by bicycle or walking by obese people.

People who live in the most ‘activity-friendly’ neighbourhoods do up to 1.5 hours more physical activity a week than those in the least supportive neighbourhoods. This is according to a new international study which measured levels of exercise — mainly walking for recreation or transport — in relation to the urban environment across 14 diverse cities. The results show how urban design — such as parks and local amenities — can promote healthy lifestyles which also bring environmental benefits, such as better air quality, through reduced car use.

Research into future climate scenarios suggest that by 2100, climate change could lead to annual damages in the EU from river flooding alone of €14 billion to €21.5 billion, with more people affected than today, and a reduction in household welfare.
