Neuroscientist, studied visual perception and short-term memory in common marmosets. Now on to other things, opinions are my own.

@faintlimits People who suffer from schizophrenia have different patterns of saccades, especially around faces, but one of the classic signs of schizophrenia is that they can't follow moving objects smoothly. They make "stairstep" saccades instead of tracking continuously.

@invertedcapital @evasmagacz @StatisticUrban Perhaps by looking at the rate of median arteries in people who grew up during periods of famine?

[Hayden Carney @theHaydenCarney]

@Surendar__05 @kratomthug That's pretty close to what a PhD student makes!

@Jack_Forge13 @reallyoptimized @RealDoctorMike @whitfieldlewis6 @Brady_H They're saying the standard of care is different now than it was before SPECT was invented, so a truly fair test of whether SPECT improves outcomes would need randomized patient groups at the same centers/hospitals at the same time.

@MakeAugusta @lukeweston From what I've heard it's the military industrial complex! TI was looking for new markets after ICBM contracts slowed down and achieved market dominance through their expertise at lobbying (step by step instructions in textbooks, only TI calculators on standardized tests, etc.).

@teslavangelist @DrSamuelBHume To be fair, that means the new treatment halved the number of unsuccessful cases (~6% -> ~3%). Given the number of people who get malaria, that's pretty impactful.

@UrbanCourtyard @curiouskiwicat That location is in the middle of the bar district of a large state university. There are a dozen bars within 500ft and literally every bar in town is within 2000ft. It's on the busiest road in town. This is not somewhere families want to live.

@LarryVroom71313 @washingtonpost Retrospective just means that they analyzed existing data, instead of planning a study where patients were assigned to different treatments and then analyzed (prospective study). Retrospective studies are very common and are good for looking at large populations.

@tom_jiahao Smell is incredibly easy when you assemble things out of molecules like biology does. There's no fundamental difference between smell and other chemical receptors. We've had mechanical touch for a long time (buttons, spring loaded things, etc.), it's human level that's hard

@YSvechinsky @yoltartar @sridatta It's all about energy. At the low energy/low frequency end (infrared), a switch that can be flipped by a photon can also be flipped by thermal noise. At the high energy (ultraviolet) end, you're limited by the strength of individual bonds within the molecules.

[Hayden Carney @theHaydenCarney]

@Drew_B_Carter @dissproportion That's not uncommon in clinical trials where the standard of care is ineffective or the disorder is sufficiently dangerous. Most of those studies compare standard of care vs standard of care+new thing, though, so you're really just adding treatment.

@ToughSf It reminds me of promotional work for Planetary Resources https://t.co/hHjxCfPuDv

@DataRepublican That is not from the NIH and would not be reviewed in the same way.

@Dieter75 @CJHandmer Cheap electricity is one thing Iceland has in large amounts, between their hydroelectric and geothermal resources. The low cost of electricity is what enables them to be a major aluminum refiner.

@bobatesomemayo @MoneyPhosphorus 40 years isn't so bad, most of the crew from the launch would probably still be alive. 10-30% seems to be doable between beamed propulsion, pellet streams, solar wind shear sailing, and q-drive (plasma magnet, not the reactionless one).

[Hayden Carney @theHaydenCarney]

@RevelansMentis @alexriesart House of Suns is a great one of his, too. Standalone story set in a far transhuman future focused on a galactic mystery being investigated by relativistic explorers and strange aliens across deep time.

@PhotonPhalinx @CE0ofClownery @CedarGodlike @ArmandDoma @GeneralTulliu5 @vanillaopinions Not all research has obvious utility, but long term the strategy works. The NIH generates about $2 of value for every $1 it spends. An ROI of 2x is great by investment standards, but you usually don't find out if the project was useful for years. Shareholders don't like that.

[Hayden Carney @theHaydenCarney]

@PhotonPhalinx @CE0ofClownery @CedarGodlike @ArmandDoma @GeneralTulliu5 @vanillaopinions The bureaucrats who review and approve research grants are experts, and often the primary review is by expert external volunteers. The NIH, for example, brings in review boards of professors from across the country to read, debate, and select which grants to fund.

@TaylorSMarks @SpaceflightNow It could get a payload to Low Mars Orbit, but the delta V required to get back from LMO is considerably higher than returning from the lunar surface. Earth reentry is much harder from Mars, too.
