It’s just fun and  gorgeous , and it’s  (see through )  so we can see each other ,all the barbies in their own  barbie dream houses wake up in the morning , and then can wave at each other . This is a product of  so many discussions , so many references , I can’t even tell you the meeting we’ve had   about the pink . We sat with all these difference kinds of pinks and we were  like what is pink ,how does the pink interact . Because we didn’t want it  to be so classy that  it didn’t . When I was a litter girl ,  I like the pinkest  brightest  thing . Because barbie was invented in 1959 , and it felt like we can ground everything  in that  look , 1950 soundstage   musicals. (Gene Kelly ) or  (Vincente Minnelli) ,like those  kind of wonderful fake  but emotionally ) artificial spaces . One thing that  those  soundstage musical did so well were beautiful artificial skies . There is a sort of surrealness of the  (gradation) of the colorYou can light (them into these intense colors  ,you can light pink and orange form the bottle ,the blue from  the top , you can really go (kind of expressionistic ) with it surrealness.  超现实gradation 渐变层次expressionistic 表现主义

EP42 cute aggressive

EP42 cute aggressive

Watching  a kitten fumbling around , it might feel as if you’ve  never encountered anything so devastatingly adorable in your mortal live . But you may also feel the conflicting urge to squeeze or smush the kitten . This urge  which phycologists call cute aggression ,is a surprisingly common one estimate to affect about a half of all adults . Cut aggression is importantly not link to the actual intention to do harm,  instead it seems to result  from emotional overload . Some scientist think the cute things (elicited) such positive emotions from certain people ,that the  experiences becomes overwhelming .  They hypothesize that sightly  aggressive  discordant  thoughts ,are the brain’s way of  putting the  brake on, and regulating those intense feelings , not getting you to actually eat a kitten . elicited 引出hypothesize 假设estimate to affect 估计影响discordant 不和谐的

EP41 how to diet

EP41 how to diet

7/15Diet is the behavior that’s been studied the most in terms of trying to affect thing like  aging and longevity.There really three components of diet that seem to be impacting aging :So the first is. How much we eat , the second is what we eat , and the third is when we eat . So in terms of how much we eat , a lot of science went into this idea of caloric restriction . Caloric restriction isn’t a starvation .it’s usually just about a 20 precent reduction in the overall caloric intake . The other thing , that has  been study , is this concept  of what we eat ,  a lot of research has  gone into whether things  like plant-based diet  are actually beneficial to  aging and longevity, there  seems to be some evidence ,that eating less animal products , more fruit ,veggies , more wholefoods ,it’s going to  be better overall . But  what scientists found , is actually fasting can (con mimic ) some of the benefits , that we’ve seen with (caloric restriction ) , so if people can perhaps minimize their eating to a small window , we think (that this  can actually recapitulate ) a lot of benefits , that we are saying in the  caloric restriction studies .

EP40 Grit

EP40 Grit

7/8In all those very different contexts ,one characteristic emerged  as a significant predictor  of  success . And it wasn’t social (intelligences  ), wasn’t good looks  , physical health , and it wasn’t IQ . It was grit . Grit is passion and perseverance for very long term goals  . So far the best idea I’ve  heard about building grit in kids  , is something called growth (mindset ) ,this is an idea  developed at sanford university  by (Carol  Dweck ) . And it is the belief that the ability to learn is not fixed .that it can change with your effort . Doctor (Dweck ) had  shown that when kids read and learn about the  brain . And how it changes and grows in response to challenge , they are   must  more likely to preserver when they fail.  Because they don’t believe  that failure is permanent  condition

Creamy , rich new York  style cheesecake is one of the city’s  most iconic desserts , the simple cheesecake recipe calls for cream-cheese ,sugar and eggs . At each spot ,we will be judging  based of the  three qualities . The filling , it should be smooth , (creamy ) and light.The topping , it should add the refreshing brightness  to a rich cheese cake .The crust ,if there is a crust , it should add texture and flavor to the overall cheese cake . Ok ,that I can get so down with, I really like that one , it’s sweet and tart, and I think I just prefer  more like  a fruit on my cheesecake , the plain is good ,but this like next level .For someone who doesn’t like cheesecake , yeah ,they should eat this . I like also, how it taste almost like a meringue, because they whip (their egg white ) a lot ,so it’s fluffier , not so dense .meringue 蛋白霜 蛋白酥Dense 浓稠fluffier 轻柔Tart  酸的Plain  无装饰的Iconic 象征性的

EP35 three qualities in pancake

Thousands of breakfast and  brunch places  are (strewn throughout ) New York City ,but only a few are famous for their pancakes . At  each place we will be looking at 3 qualities . 1 . We’re looking at (texture) ,the pancake  should be fluffy ,  and cooked all  the way through , and not too dry .2 . We ‘re looking for color ,we are looking for golden brown pancake that (ensures a slight ) crispiness  on the exterior of the  pancake And finally ,three , toppings, we’re looking at a toping that will accompany the pancake ,but not steal a spotlight .They are just like the perfect balance  of sweet , savory ,luxurious deliciousness  . Basically ,a pancake  is cake batter . So when you (flip ) it , all the active ingredients like salt and sugar , and baking powder ,and  all of that , ,it’s a chemical  reaction , when you flipped  it ,that’s when  in rose ,and those active ingredients  are making a cake rise , and  that’s the less  scientific explanation for it .strewn 散播fluffy 轻柔texture质地savory 可口的，咸的batter 面糊

6/10 Tonight we’re going to be taking a look  at some  brilliant new  technology that can find (biomarkers ) of a cancerous tumor  in just 3 minutes compared to  3 weeks with normal technology . That means thousands  of people could get treatments much sooner   than ever , which is crucial, because when it comes to brain surgery, every second counts . It  really  is hard for clinicians  and patients , i think  ,to wrap their heads around that waiting period  But now using  (groundbreaking ) artificial intelligence , Arranger invented a device called deep (glioma )  , that can predict the genetics of a tumor in less than 3 minutes ,  a process that can take up  to 6 weeks .One recent  study found deep glioma was 93 precent accurate compared to the usual method .  Dr. Schenoodle, you are a pathologist here ,how big of a  deal is this  .It’s  an incredible advancement . We can have molecular  diagnosis in 3 minutes , instead of  3 weeks . Further research is  needed , but the hope is that this  technology could  help patient like (George ) start treatment earlier  before the tumor has  chance to grow bigger . molecular 分子的diagnosis 诊断biomarkers 生物标记crucial 至关重要的

Tell me some of the things that it is  looking at ,so obvious things like if someone presses like or stay on a video for a  long time ,that give you a clue more like that . But is it subject matter ? what are the  array of things you have notice , that you can actually track that provide useful clues .I’m going to simplify this a lot ,but the machine learning the recommendation ,algorithm   ,is really just a math . So for example , if you like videos ,1.2.3.and  4 , and I like videos 1,2,3,and 5. Maybe he like videos 1,2,3,and 6, now what’s going to  happen is  ? Because we like 123 at same time ,he is going to  be shown 456 ,  so are we .And you can think about this repeat at  scale  in  real time ,across more than a billion people ,that’s   basically what it is  ,it’s  math , and of course you know ,AI and machine learning has allowed this to be done , at very very big scale , what we have seen  the result of this ,is that they learned the interest signals that people exhibit very quickly and shows you  content really relevant for you , in a very quick way .

EP26 starship explosion

By the  end of 2022, spaceX was preparing for a key test ,starships first test flight  using  both parts of the racket. Musk  said the year  before that there was lot of risks associate with the  first launch  I would not say like ,it is likely to be success , but I think we will make a lot of progress .The plan was for starship to take off from the launch part in Texas . The boost would then separate and fall into the Gulf of Mexico as the spaceX engines fired and took it in a   90 minutes flight . Then it would come down ,and crash in the pacific ocean ,  but that’s not what happened ,shortly  after starship launched at  9,33am eastern . A graphic  on the live stream  indicated that three engines were not working .  With more  appearing to  go out before the blast .The shutter that was intended to separate from booster here . Didn’t After climbing 24miles , the racket began to tumble back to earth , and around 4 minutes into its flight , starship explored .SpaceX said a flight termination system  was  triggered on  both this spacecraft  and the  booster . When you have a failure ,you learned a lot from that failure  . So I think their plan was to test to the point of  failure ,and then let’s learn  from what  we can from that  failure ,so it never happens again .tumble 翻滚shutter 快门booster 助推器

That’s  two ways  to unlock energy from hydrogen that’s  coming out here .firstly it’s flammable ,so you could just  burn it .and secondly ,you could use to  power ,what’s called a flue cell .This essentially  work  like a battery running on hydrogen or oxygen ,they react to supply to electricity that could for example, power of car. The only by-produces are heats and water ,and all of this is not really  news , the fuel cell  was invented back in  1800s ,later on the same century ,the guy in Denmark ,was called KuMepuwa ,was already use windmills to  power electrolysis   ,that supplied  hydrogen for school  gas lamps, and  in 1960s , general motors  built flue power van ,that run an hydrogen Today ,almost hydrogen we  produced   is used to make other things ,like fertilizers  or petroleum , but it’s never made it big as  a fuel .it’s just always be easier and cheaper to directly burn fossil fuels instead, But that is changing .essentially。本质上fertilizers   肥料petroleum  石油 原油electrolysis 电解hydrogen  氢气

What is Parkinson’s disease ?Let’s start with  some basics . In the united states ,it’s estimated that anywhere from 600 000 to 1 million people and more are living with Parkinson’s .and at least  6 000  are diagnosed each year. This makes PD , one of the most common brain  diseases ), second only to Alzheimer’s , age increase of risk of Parkinson’s ,and average age of diagnosis  is  60 , so as our population continues growth get older, and more people are likely to experience PD ,in fact ,people tends to think of  Parkinson’s as an old person disease ,but some person get PD  at 40  or even younger , some disease  can be diagnosed with a lab test ,cholesterol level ,and (blood pressure ) measures to  evaluate for heart disease for example .We need to test like that in Parkinson, but they don’t exist yet  ,doctors diagnosed Parkinson by completing  medical history and physical examination , they look for two and three classical motor  symptoms which are resting tremor .
