BACKGROUND AND PURPOSE:

Low-field 64 mT portable brain MRI has recently shown diagnostic promise for MS. This study aimed to evaluate the utility of portable MRI (pMRI) in assessing dissemination in space (DIS) in patients presenting with optic neuritis and determine whether deploying pMRI in the MS clinic can shorten the time from symptom onset to MRI.

BACKGROUND AND PURPOSE:

Intracranial vessel wall imaging is technically challenging to implement, given the simultaneous requirements of high spatial resolution, excellent blood and CSF signal suppression, and clinically acceptable gradient times. Herein, we present our preliminary findings on the evaluation of a deep learning–optimized sequence using T1-weighted imaging.

Surprisingly little attention has been given to the impact of selfing on speciation, even though selfing reduces gene flow between populations and affects other key population genetics parameters. Here we review recent theoretical work and compile empirical data from crossing experiments and genomic and phylogenetic studies to assess the effect of mating systems on the speciation process. In accordance with theoretical predictions, we find that accumulation of hybrid incompatibilities seems to be accelerated in selfers, but there is so far limited empirical support for a predicted bias toward underdominant loci. Phylogenetic evidence is scarce and contradictory, including studies suggesting that selfing either promotes or hampers speciation rate. Further studies are therefore required, which in addition to measures of reproductive barrier strength and selfing rate should routinely include estimates of demographic history and genetic divergence as a proxy for divergence time.

The post RPG Cast – Episode 658: “Space Marines Were in the Bible” appeared first on RPGamer.

Stationeers and Icarus developers RocketWerkz are making a spiritual successor to beloved space sim Kerbal Space Program, which is currently titled "Kitten Space Agency" in a flagrant display of adherence to wholesome internet trends. It's based on an actual Kerbal Space Program 2 pitch the studio threw at Take-Two subsidiary Private Division back in the day. RocketWerkz CEO and original DayZ creator Dean Hall has hired several former KSP and KSP2 developers to work on the game, and is describing it on social media as a "KSP killer".

To say that Factorio: Space Age throws out the rulebook is an understatement. It'd be more fitting to say it's somehow automated the whole process: an inserter plucked out the rulebook from my brain and deposited it in hot magma, while a new rulebook was churned out in a nearby machine and plopped into my brain from the other side - only for that to be immediately plucked out and incinerated as well. With each new planet and each new phase, Space Age reinvents itself. I'm battling hyperbole here, but ah hell, I admit defeat. Factorio: Space Age is a masterpiece, the final form of perhaps the most well-crafted building game I'll ever play.

Could tower defence be the ultimate "it's Friday and I am here in body only" genre? I haven't really thought about it before, but Rift Riff's effusively laidback crowd control has me pondering those optimal moments in any tower defender when the incoming horde hits the flamer-MG triangle just right, and you can settle back comfortably into the role of clockwatcher.

Rift Riff encourages this behaviour by being nice to look at. Created by a trio of developers including Hidden Folks designer Adriaan de Jongh, it's a world of spacey, sun-carved mountains, forests and monoliths. The towers resemble the sacred architecture of Monument Valley, and the colour scheme and general ambience remind me of Cocoon. There's a demo, if you fancy it.

"Where’s my Neo-Volkite pistol, Warhammer 40,000: Space Marine 2?" was my perhaps slightly ungrateful reaction upon booting the action game up after the previous patch. "I didn’t even know what a Neo-Volkite pistol was until five minutes ago, but now this whole game is trash until I get one!." As promised in the roadmap, the last big update added a whole new Operations map, complete with a gargantuan new pseudo-boss in the form of a hierophant bio-titan. It did not, however, give me my beloved pistol. It’s fine. It’s in now, along with a few, less Neo-Volkite updates to other weapons.

The success of the all-civilian spacewalk on SpaceX’s Polaris Dawn mission shows that private space flight is starting to catch up with government space agencies
