Great idea to combine a sleeping-pod hotel with transportation. I've often thought that airplanes could do the same, fitting just as many people in lengthwise as they do in the normal sitting configuration, by stacking pods on top of each other.

Stunt robots
Can adjust their limbs to change their rotation mid-flight and stick a perfect landing. Could be used to test a stunt before a human stunt person does it.
Astrobleme - crater left after asteroid impact
The West and East Clearwater Lake impact structures are two of the most distinctive and recognizable impact structures on Earth.

West and East Clearwater Lake 56°12'45.0"N 74°30'38.8"W
Manicougan Lake 51°21'39.9"N 68°41'47.8"W
There are lots more astroblemes in North America alone, but the above 2 are remarkable.
Here's a map of the craters in North America:
Cautery vs Scalpel for skin incisions?
I really don't understand why we're continuing to use scalpels for skin incision. Using the 'cut' option in cautery is faster, causes less blood loss and pain, and does not increase infections, in multiple studies.
Diathermy versus scalpel incisions in elective abdominal surgery: a comparative study.
"There was a significant increase in mean time taken for incision by scalpel when compared to cautery. Mean incision blood loss ...and postoperative pain was significantly higher in the scalpel group (p value <0.05) on postoperative day 1."
Advanced Cutting Effect System versus Cold Steel Scalpel: Comparative Wound Healing and Scar Formation in Targeted Surgical Applications.
"modern electrosurgical generators that produce pure sinusoidal "CUT" waveforms have shown reductions in thermal damage along incisions...Results showed noninferior wound healing/scar formation in skin incisions made with [cautery] compared with incisions made with a [scalpel].
Comparison of electrocautery incision with scalpel incision in midline abdominal surgery RCT. "...mean incision time per unit wound area in the electrocautery group and scalpel group was 9.40 ± 3.37 s/cm2 and 9.07 ± 3.40 s/cm2 (p = 0.87) respectively. The mean blood loss per unit wound area was significantly lower in the electrocautery group at 6.46 ± 3.94 ml when compared to that of 23.40 ± 15.28 ml in the scalpel group (p= < 0.0001, CI = 11.97–21.89). There was no significant difference in pain [or] wound infection rates…"
A comparative study to evaluate the outcome between electrocautery versus scalpel skin incision in tension-free inguinal hernioplasty: a tertiary care teaching centre experience. "...incision time was shorter in the electrocautery group (P <0.001). The blood loss was less with the electrocautery compared to the scalpel (6.53±3.84 ml vs. 18.16±7.36 ml, P<0.001). The cumulative numerical rating scale score for pain was 12.65 (standard deviation SD 8.06) and 17.12 (SD 9.49) in the diathermy and scalpel groups respectively (P<0.001). There was no statistically significant difference in wound infection and wound closure
(epithelialization time) (P=0.206)..."

How to Travel the World After You Retire | Travel + Leisure
Look for person to person experiences.
In this age of increased longevity, costly health care, and declining availability of pensions, many retirees find that their savings and investments are not adequate...Chief Financial Analyst Greg McBride of Bankrate.com...advises pre-retirees to build travel costs into anticipated retirement expenses as opposed to waiting until retirement to figure out how to pay for travel. He warns against pulling too much money from savings early in retirement...use credit cards that offer attractive rewards. “They can fund significant travel expenses..”
Peggy Goldman, president and founder of Friendly Planet Travel...“Individuals have to be realistic about themselves, what they’re capable of, and what arrangements they need. We advise them not to limit themselves in terms of selecting programs — if they feel good and can do it, they should go for it.”
“People want to interact with locals; they want to get their hands dirty in the kitchen, meet people in their homes,” she said. “That’s what is so wonderful about people-to-people experiences and optional excursions. It’s more than just visiting monuments; it’s about having experiences with people.” [for example -] visitors to Hangzhou can visit tea plantations for demonstrations on how agricultural workers select and pick the leaves. Travelers get a chance to do it for themselves and gain a new appreciation for the tea they’re drinking.
Volunteer vacations offer travel along with an opportunity to contribute skills and experience to others both domestic and abroad. Many seniors are finding these trips to be rewarding, and they can also fulfill the desire to interact with locals and broaden cultural experiences. Others enjoy “learning vacations,” traveling for workshops, conferences, cooking schools, cultural programs, or music festivals.

Why we pee less at night
Circadian rhythm of glomerular filtration rate in normal individuals.
"...circadian rhythm for GFR with a maximum of 122 ml/min (SD 22) in the daytime, a minimum of 86 ml/min (SD 12) at night..."

How Capitalism Ruined China’s Health Care System | NYT
Medicine in China being compared to a caste system - limited availability of specialists who see 6x as many patients per day as the US, scalpers selling tickets in line to see doctors, violence in hospitals (see 6:04 onward) out of frustration with the system. And a man blindly making random home-made chemo in his living room in desperation.

Former CIA Chief Explains How Spies Use Disguises.
At 8:40, she says "We can make you taller, older, heavier, but not the other way."
It's also nearly impossible to go from man to woman.

The Quest to Make Lab Grown Meat
As with humanoid robots and animation, they're hitting a wall of the "uncanny gap" or "uncanny valley" which occurs when an imitation becomes very realistic, suddenly the differences between real and imitation become heightened, and repulsive. Because your brain is hard-wired to protect you from food that is not the real thing. Fear of clowns or coulorophobia may be rooted in the same phenomenon.
People who remember every second of their life
Something I never know about Mary Lu Henner from Taxi.
This feat of memory is astounding. MRI shows their caudate nucleus is up to 7 times larger than average.
This boy remembers almost every day, but not every day if his life.

At 0:54 he mentions the Gruen effect of how architecture affects buying. Paradoxically, the effect is that of drawing customers inside with elaborate displays, and yet he is considered the father of shopping malls which he designed with blank exteriors, leaving the luring windows until customers are inside.
