00:00:00.000 --> 00:00:06.950
Hello, I'm Micah Finch. Today is Monday, September 21, 2026, in New York, and this

2
00:00:06.950 --> 00:00:09.373
is your Lol What Daily Briefing.

3
00:00:09.373 --> 00:00:14.020
This edition covers verified developments published or updated between 12 AM Eastern

4
00:00:14.020 --> 00:00:22.301
on Sunday, September 20, and 4 48 AM Eastern today, a window of 28 hours and 48 minutes.

5
00:00:22.301 --> 00:00:27.603
We begin with a tiny robot, whose cleverest feature is not any single movement, but the

6
00:00:27.603 --> 00:00:30.185
way one structure performs several jobs.

7
00:00:30.240 --> 00:00:34.212
Researchers have described a 140 milligram robot that can take off,

8
00:00:34.212 --> 00:00:39.057
crawl across level ground, glide on water, and move from the surface into the water.

9
00:00:39.057 --> 00:00:41.996
The central idea is what the team calls functional recursion.

10
00:00:42.632 --> 00:00:45.571
Instead of adding a separate mechanism for every behavior,

11
00:00:45.571 --> 00:00:49.702
shape-memory alloy artificial muscles deform the same H-shaped frame.

12
00:00:50.416 --> 00:00:53.912
In the air, that frame changes the wing motion to influence attitude.

13
00:00:54.468 --> 00:00:56.851
On land, it oscillates to produce a crawl.

14
00:00:57.486 --> 00:01:02.649
At the water surface, it adjusts kirigami-inspired foot pads that use surface tension for support.

15
00:01:03.205 --> 00:01:07.574
The machine is 35 millimeters long, so the engineering challenge is severe.

16
00:01:08.130 --> 00:01:12.499
Every extra actuator adds mass that can compete with lift, payload, and control.

17
00:01:13.134 --> 00:01:16.868
The result, published today in Microsystems and Manu-Engineering,

18
00:01:16.868 --> 00:01:20.839
is a compact demonstration of doing more with fewer dedicated parts.

19
00:01:20.998 --> 00:01:24.335
There is an important boundary around that achievement.

20
00:01:24.335 --> 00:01:27.075
The paper does not show one fully autonomous trip

21
00:01:27.075 --> 00:01:30.133
from flight to land, to water, and then underwater.

22
00:01:30.133 --> 00:01:32.596
These were representative open-loop tests,

23
00:01:32.596 --> 00:01:34.383
and the robot remains tethered.

24
00:01:34.383 --> 00:01:36.806
Its external power, control electronics,

25
00:01:36.806 --> 00:01:39.903
and communications are not included in the quoted mass.

26
00:01:39.903 --> 00:01:42.366
Flight stabilization is also unfinished,

27
00:01:42.366 --> 00:01:45.742
and touchdown is especially difficult without feedback.

28
00:01:45.742 --> 00:01:48.681
Still, the measured pieces are interesting.

29
00:01:48.721 --> 00:01:51.580
It crawled at 15.3 millimeters per second

30
00:01:51.580 --> 00:01:53.089
with an eight hertz gate.

31
00:01:53.089 --> 00:01:56.068
Its feet could support a load equal to 1.7 times

32
00:01:56.068 --> 00:01:58.411
its body weight at the water surface.

33
00:01:58.411 --> 00:02:02.244
An electro-wetting process operating at 225 volts

34
00:02:02.244 --> 00:02:04.528
then helped rupture that supporting interface

35
00:02:04.528 --> 00:02:06.474
for controlled immersion.

36
00:02:06.474 --> 00:02:08.619
The larger lesson is architectural.

37
00:02:08.619 --> 00:02:11.637
At insect scale, a structure that changes roles

38
00:02:11.637 --> 00:02:13.603
may be more valuable than a collection

39
00:02:13.603 --> 00:02:15.807
of exquisitely specialized mechanisms.

40
00:02:16.022 --> 00:02:20.391
South Korea's customs agency reported a striking early-month trade reading.

41
00:02:21.106 --> 00:02:26.428
From September 1 through the 20th, preliminary exports reached $71.4 billion,

42
00:02:27.381 --> 00:02:35.483
up 78.3% from the same period last year. Imports rose 26.7% to $48.4 billion,

43
00:02:36.039 --> 00:02:39.137
leaving a provisional surplus of about $23 billion.

44
00:02:39.137 --> 00:02:49.463
Semiconductors supplied $34.12 billion of exports, up 259.4%. That means chips accounted

45
00:02:49.463 --> 00:02:55.977
for almost 48% of all export value in this 20-day snapshot, by a straightforward calculation

46
00:02:55.977 --> 00:03:01.934
from the customs figures. The calendar does not explain the surge away, the period had 15.5

47
00:03:01.934 --> 00:03:07.495
working days, one fewer than last year, while average exports per working day rose 89.8%.

48
00:03:08.448 --> 00:03:12.976
Shipments to China more than doubled, and those to the United States rose 118%,

49
00:03:13.691 --> 00:03:16.947
according to Yonhap's account, of the same release.

50
00:03:17.289 --> 00:03:22.055
Those numbers are unusually large, but they are not yet a final monthly result.

51
00:03:22.055 --> 00:03:26.900
They are customs-cleared, nominal values for a partial month, and product prices can move

52
00:03:26.900 --> 00:03:32.540
the dollar total as well as shipment volumes. The useful signal is narrower. In this measured

53
00:03:32.540 --> 00:03:36.830
period, chip exports were both the largest component and the dominant source of the

54
00:03:36.830 --> 00:03:44.614
increase. Cars rose 9.3 percent and petroleum products 47.8 percent, while mobile device

55
00:03:44.614 --> 00:03:50.492
exports slicked 0.4 percent. The contrast matters, because it shows concentration.

56
00:03:51.128 --> 00:03:55.814
A broad-looking national export boom can still depend heavily on one product cycle.

57
00:03:56.609 --> 00:04:01.533
Final September data will be needed to tell whether the first 20 days represent the whole month.

58
00:04:01.732 --> 00:04:09.516
Bangladesh's health emergency dashboard, updated Sunday, recorded 1,593 dengue hospital admissions

59
00:04:09.516 --> 00:04:14.997
and six deaths in the preceding 24 hours. The national totals for 2026

60
00:04:14.997 --> 00:04:24.927
reached 61,972 reported admissions and 184 deaths. The same update recorded 1,587 discharges during

61
00:04:24.927 --> 00:04:33.029
that day, bringing reported recoveries to 57,610. These are surveillance counts, not an estimate of

62
00:04:33.029 --> 00:04:37.398
every infection, many dengue infections are mild or never enter hospital data.

63
00:04:37.954 --> 00:04:44.070
The geographic tables add useful context. Among cases classified inside or outside designated

64
00:04:44.070 --> 00:04:50.663
city corporation areas, about 76% were recorded outside them. That does not identify a cause,

65
00:04:50.663 --> 00:04:55.508
and the dashboard's category totals contain small inconsistencies, but it does show that

66
00:04:55.508 --> 00:04:59.083
the recorded burden is not confined to the largest urban jurisdictions.

67
00:04:59.639 --> 00:05:03.055
The latest daily deaths were reported across four divisions.

68
00:05:03.055 --> 00:05:08.917
Typhoon Dujuan was nearing eastern Japan on Monday, disrupting transport and bringing

69
00:05:08.917 --> 00:05:12.690
a serious rainfall risk around the Pacific coast.

70
00:05:12.690 --> 00:05:19.760
Reporting published at 1.24pm Japan time said at least 275 flights had been cancelled, 135

71
00:05:19.760 --> 00:05:23.811
by Japan Airlines and 140 by All Nippon Airways.

72
00:05:23.811 --> 00:05:30.086
Some rail services were suspended, and more than 4,000 households in Chiba lacked power.

73
00:05:30.086 --> 00:05:34.058
Reporters reported that parts of the Izu Islands and Pacific coast had already received

74
00:05:34.058 --> 00:05:37.513
more than 300 millimeters of rain since Saturday.

75
00:05:37.513 --> 00:05:42.716
Oshima, south of Tokyo, was under the highest-level landslide emergency warning.

76
00:05:42.716 --> 00:05:46.211
The practical hazard is not only the storm's center.

77
00:05:46.211 --> 00:05:50.540
Japan's weather agency warned that narrow, persistent rain bands could sharply raise

78
00:05:50.540 --> 00:05:52.804
flash flood and landslide risk.

79
00:05:52.804 --> 00:05:55.624
Conditions and transport schedules can change quickly.

81
00:05:59.262 --> 00:06:04.346
In Indonesia, the search continued for people missing from the sunken Virgo Transport 8

82
00:06:04.346 --> 00:06:09.985
in the Java Sea. Indonesia's National Search and Rescue Agency said that as of noon Central

83
00:06:09.985 --> 00:06:16.856
Indonesia time on Monday, 120 of the 243 people listed on the manifest had been found. Of

84
00:06:16.856 --> 00:06:23.707
those, 108 survived and 12 had died. 123 remained missing. Two people were recovered on Monday

85
00:06:23.707 --> 00:06:28.930
morning during an underwater search, according to the agency statement carried by Antara.

86
00:06:28.930 --> 00:06:33.359
This was the ninth day of the operation, with air and sea resources still deployed.

87
00:06:33.359 --> 00:06:37.866
The figures are an official operational count, not a final accounting, and investigations

88
00:06:37.866 --> 00:06:43.089
into the loss of the vessel are separate from the immediate search. The scale of the unresolved

89
00:06:43.089 --> 00:06:46.425
manifest makes this a significant continuing rescue effort.

90
00:06:46.588 --> 00:06:52.029
Australia's new long-range fiscal outlook puts slower population growth and aging near

91
00:06:52.029 --> 00:06:54.373
the center of its economic planning.

92
00:06:54.373 --> 00:07:01.045
The Treasury's Intergenerational Report projects average population growth of 0.9% a year over

93
00:07:01.045 --> 00:07:06.367
the next four decades, down from 1.4% over the past 40 years.

94
00:07:06.367 --> 00:07:11.530
It also projects that deaths will exceed births sometime in the 2060s, meaning migration would

95
00:07:11.530 --> 00:07:14.549
become the remaining source of population growth.

96
00:07:14.549 --> 00:07:17.369
This is a scenario, not a scheduled event.

97
00:07:17.369 --> 00:07:22.452
Fertility, migration, health, and longevity can all change over 40 years.

98
00:07:22.452 --> 00:07:25.431
The immediate policy mechanism is easier to see.

99
00:07:25.431 --> 00:07:30.197
An older population tends to increase demand for health and aged care workers, while reducing

100
00:07:30.197 --> 00:07:33.692
the share of people in conventional working ages.

101
00:07:33.692 --> 00:07:36.870
Regions that are already older may feel that mismatch first.

102
00:07:36.870 --> 00:07:42.311
Productivity, training, care technology, workforce participation, and migration settings can

103
00:07:42.311 --> 00:07:46.997
each alter the outcome, but none removes the underlying arithmetic by itself.

104
00:07:47.164 --> 00:07:48.753
I'm Micah Finch.

105
00:07:48.753 --> 00:07:50.778
Thanks for listening.
