Actin waves transport RanGTP to the neurite tip to regulate non-centrosomal microtubules in neurons [RESEARCH ARTICLE]

Yung-An Huang, Chih-Hsuan Hsu, Ho-Chieh Chiu, Pei-Yu Hsi, Chris T. Ho, Wei-Lun Lo, and Eric Hwang

Microtubule (MT) is the most abundant cytoskeleton in neurons and controls multiple facets of their development. While the MT-organizing center (MTOC) in mitotic cells is typically located at the centrosome, MTOC in neurons switches to non-centrosomal sites. A handful of cellular components have been shown to promote non-centrosomal MT (ncMT) formation in neurons, yet the regulation mechanism remains unknown. Here we demonstrate that the small GTPase Ran is a key regulator of ncMTs in neurons. Using an optogenetic tool that enables light-induced local production of RanGTP, we demonstrate that RanGTP promotes ncMT plus-end growth along the neurite. Additionally, we discovered that actin waves drive the anterograde transport of RanGTP. Pharmacological disruption of actin waves abolishes the enrichment of RanGTP and reduces growing ncMT plus-ends at the neurite tip. These observations identify a novel regulation mechanism of ncMTs and pinpoint an indirect connection between the actin and MT cytoskeletons in neurons.

Bayesian machine learning improves single-wavelength anomalous diffraction phasing

Single-wavelength X-ray anomalous diffraction (SAD) is a frequently employed technique to solve the phase problem in X-ray crystallography. The precision and accuracy of recovered anomalous differences are crucial for determining the correct phases. Continuous rotation (CR) and inverse-beam geometry (IBG) anomalous data collection methods have been performed on tetragonal lysozyme and monoclinic survivin crystals and analysis carried out of how correlated the pairs of Friedel's reflections are after scaling. A multivariate Bayesian model for estimating anomalous differences was tested, which takes into account the correlation between pairs of intensity observations and incorporates the a priori knowledge about the positivity of intensity. The CR and IBG data collection methods resulted in positive correlation between I(+) and I(−) observations, indicating that the anomalous difference dominates between these observations, rather than different levels of radiation damage. An alternative pairing method based on near simultaneously observed Bijvoet's pairs displayed lower correlation and it was unsuccessful for recovering useful anomalous differences when using the multivariate Bayesian model. In contrast, multivariate Bayesian treatment of Friedel's pairs improved the initial phasing of the two tested crystal systems and the two data collection methods.

The Second Massive Downwave Is Almost Upon Us

Source: Clive Maund for Streetwise Reports   05/04/2020

Technical analyst Clive Maund charts the markets and discusses what he believes is ahead for stocks, the dollar and commodities.

Notwithstanding the Fed's seemingly limitless ability to create money to throw at the stock market, which has caused it to rally in recent weeks in the face of a dead economy and apocalyptic jobs data and earnings, etc., all the charts we are going to look at here point to another severe downleg soon.

My attention was drawn to a bearish Rising Wedge completing in the London FTSE index by a colleague in England. So I took a look at it, and sure enough it is. So, I thought I'd take a look at a couple of other European indices, the CAC 40 in France and the German DAX Composite, which showed a very similar picture. Their charts are shown below and as you will see, they are both very bearish, and point to a break lower soon leading to a severe decline.


You will recall that we were thrown somewhat a week or two ago, when the main U.S. indices, the Dow Jones Industrials and the S&P500 index, broke down from their bearish Rising Wedges but then didn't follow through, and instead rose to new highs for the rally from the March lows, which caused us to dump our Puts and then bide our time to see what transpired. The sharp drop at the end of the month—this past Friday—jolted me into action and prompted me to hunt around in a quest for greater clarity regarding what is going on, and it has turned out to be a rewarding search.

While it's not exactly clear what is going on with the main U.S. indices, the picture becomes much clearer when we look at the broader but much less used Wilshire 5000 index. Take a look at this first of all—it's a 5-month chart for the Wilshire 5000 that reveals that it didn't break down from its Rising Wedge about 10 days ago, unlike the Dow Industrials and the S&P500 index, but it did last Friday, which happened to be the end of the month, by a significant margin. This is regarded as an ominous development that probably marks the start of the second major downleg of this bear market. We can also see that the countertrend rally got stopped by the important resistance level shown.


Now take a look at this. The following chart shows that the breakdown from the Wedge happened just two days after the Wilshire 5000 had arrived at an upper range Fibonacci target at a retracement level of 61.8% of the preceding first leg down of the bear market. This is normally as far as a retracement following the first leg down of a bear market gets, and the same happened following the Tech bubble peak in 2000 and the start of the 2007–2008 meltdown.


If we now compare the Wilshire charts above with the S&P500 index chart we realize that the breakdown by the latter about 10 days ago was a false breakdown, inasmuch as, as we have just seen, the Wilshire did not break down at that time.


If we see another heavy drop in the broad stock market shortly, it is of course reasonable to presume that it will coincide with a strong rally in the dollar, so how does that look now? On the following 5-month chart for the dollar index, which has the S&P500 index placed above and gold below for direct comparison, there are several very important points to observe. The first is that when the market tanked into mid-March, the dollar soared just as we would expect it to and as happened in 2008. Then it dropped back sharply later in March as the market rebounded, but it has since been tracking sideways in a trading range marking time as the stock market continued to ascend to complete its relief rally. Right now it is at the support at the bottom of this range where a doji candle formed on Friday suggesting that it is about to start higher again. If the market now proceeds to tank in a second major downwave then we can expect the dollar to soar again, bust out of the top of the current range and probably exceed its mid-March highs.


If the dollar soars then commodities are likely to take another broadside, just as in the first half of March, and just as in 2008, and gold and silver are unlikely to be spared—the Gold Miners Bullish Percent Index is now at an extreme reading of 92% bullish. Copper in particular looks like it will get crushed by another downwave that should take it to new bear market lows by a wide margin.

Wave and tidal energy plants are ‘green’ technologies

Environmental impacts for a wave energy device, tidal stream and tidal range plants are potentially eight, 20 and 115 times lower respectively than for coal-generated power, averaged over five impact categories. An assessment of the amount of metal used by these technologies, however, shows an impact respectively 11 and 17 times higher than for coal- and gas-based power generators. These are the findings of a recent study, which compared the life-cycle environmental impacts of various wave and tidal energy devices with other forms of energy generation. The researchers conclude that wave and tidal energy plants qualify as ‘green’ technologies according to their definition, but that their impacts on marine ecosystems need further research.

Wave farms could help prevent coastal erosion under future sea-level rise

As well as providing renewable energy, wave farms can help protect coasts against erosion by reducing the force of waves. However, it remains unknown whether they can provide this complementary service under future climate change when sea levels will be higher. A new study, based upon computer simulations, concludes that a wave farm off the south coast of Spain could indeed protect the coastline under higher sea levels, and cause the local beach to grow in size after storms.

Using microwaves to clean polluted soil could lead to energy savings

Researchers have experimented with microwave heating as a way of cleaning soils polluted with fuels, such as diesel and petrol. Soil type and moisture levels, as well as the strength of microwaves used, had a strong bearing on the overall effectiveness of the cleaning. The research shows that, at certain depths and in certain types of soil, microwaves can be a cost-effective way of cleaning polluted soils.
