Unraveling Mars’ Ancient Water History, Moon’s Ejected Origins, and the Quest for Lunar...
SpaceTime Series 28 Episode 13
Mysteries of Water on Mars and the Origins of Earth's Moon
In this episode of SpaceTime, we explore groundbreaking discoveries about the history of water on Mars. New research reveals thousands of mounds on the Martian northern plains, rich in clay minerals, indicating that this area was once submerged under a vast ocean. These findings, reported in Nature Geoscience, suggest that the mounds preserve a complete geological history of water on Mars, making them prime targets for future exploration missions searching for signs of past life.
Could the Moon be a Piece of Earth?
We also delve into a fascinating study proposing that the Moon could have formed from material ejected from the Earth's mantle rather than from the impact of a Mars-sized body, as previously thought. This new hypothesis, based on isotopic similarities between Earth and Moon samples, offers fresh insights into the origins of our lunar companion and the potential pathways for water to have reached Earth.
Establishing a Permanent Presence on the Moon
Additionally, we discuss the challenges and innovations required to establish a permanent human presence on the Moon as part of NASA's Artemis program. From 3D printing to robotics and artificial intelligence, experts outline the critical technologies needed to build infrastructure on the lunar surface and the hurdles that must be overcome to make this ambitious goal a reality.

the red planet Mars could the Earth's
00:00:14.000 --> 00:00:16.269

00:00:16.279 --> 00:00:19.310

[Music]
00:00:45.680 --> 00:00:48.069
Gary a new study has shown that
00:00:48.079 --> 00:00:49.830
thousands of mounds and hills on the
00:00:49.840 --> 00:00:51.750
baron Marsh and Northern Plains are full
00:00:51.760 --> 00:00:53.590
of clay minerals providing clear
00:00:53.600 --> 00:00:55.470
evidence that these rocks were once
00:00:55.480 --> 00:00:58.150
soaked with water the findings reported
00:00:58.160 --> 00:01:00.069
in the journal Nature geoscience
00:01:00.079 --> 00:01:01.709
supports the hypothesis that the
00:01:01.719 --> 00:01:04.229
expansive red planet Northern lowlands
00:01:04.239 --> 00:01:06.550
was once the floor of a vast Martian
00:01:06.560 --> 00:01:09.149
ocean one of the stud's authors Joe
00:01:09.159 --> 00:01:11.350
mcneel from the open University says
00:01:11.360 --> 00:01:13.310
these Mounds are all that's left of a
00:01:13.320 --> 00:01:15.390
landscape roughly the size of the UK
00:01:15.400 --> 00:01:18.429
that's been almost entirely eroded away
00:01:18.439 --> 00:01:19.749
McNeil and colleagues used
00:01:19.759 --> 00:01:21.870
highresolution images and compositional
00:01:21.880 --> 00:01:24.149
data captured by orbiters around Mars to
00:01:24.159 --> 00:01:26.190
better understand the geology of these
00:01:26.200 --> 00:01:28.390
Mounds they found that the Mounds which
00:01:28.400 --> 00:01:30.469
are up to half a kilometer High Are All
00:01:30.479 --> 00:01:32.630
That Remains of an ancient Highlands
00:01:32.640 --> 00:01:34.630
region which retreated by hundreds of
00:01:34.640 --> 00:01:36.870
kilometers after erosion wore away the
00:01:36.880 --> 00:01:39.550
terrain billions of years ago these
00:01:39.560 --> 00:01:41.749
actions played a key role in shaping the
00:01:41.759 --> 00:01:43.670
Martian landscape which divides the
00:01:43.680 --> 00:01:45.630
planet's low-lying Northern Hemisphere
00:01:45.640 --> 00:01:48.270
from its much higher southern hemisphere
00:01:48.280 --> 00:01:49.749
the Mounds are made up of layered
00:01:49.759 --> 00:01:51.870
deposits containing clay minerals formed
00:01:51.880 --> 00:01:53.749
through water interacting with rock over
00:01:53.759 --> 00:01:56.510
millions maybe billions of years these
00:01:56.520 --> 00:01:58.910
clay layers are sandwiched between older
00:01:58.920 --> 00:02:00.789
non-clay layers below and younger
00:02:00.799 --> 00:02:03.230
nonclay layers above marking distinct
00:02:03.240 --> 00:02:05.830
geological events in Martian history
00:02:05.840 --> 00:02:07.550
McNeil says the mounts are incredibly
00:02:07.560 --> 00:02:09.150
exciting because they preserve a
00:02:09.160 --> 00:02:11.029
complete history of water in this region
00:02:11.039 --> 00:02:12.910
with inaccessible continuous Rocky
00:02:12.920 --> 00:02:15.110
outcrops and that makes them a prime
00:02:15.120 --> 00:02:17.070
location for future missions aimed at
00:02:17.080 --> 00:02:19.030
uncovering whether Mars ever had an
00:02:19.040 --> 00:02:20.710
ocean and whether life could have
00:02:20.720 --> 00:02:23.350
existed there remember here on Earth
00:02:23.360 --> 00:02:26.470
wherever we find water we find life the
00:02:26.480 --> 00:02:28.430
study also reveals that these Mounds are
00:02:28.440 --> 00:02:30.070
geologically linked to the nearby by
00:02:30.080 --> 00:02:32.350
Plains of Aria Plum which the European
00:02:32.360 --> 00:02:34.630
Space Agency Rosland Franklin R is set
00:02:34.640 --> 00:02:37.190
to explore in 2028 looking for science
00:02:37.200 --> 00:02:40.030
of past and present Life by piecing
00:02:40.040 --> 00:02:41.910
together the red planet's ancient past
00:02:41.920 --> 00:02:43.990
scientists are uncovering the story of a
00:02:44.000 --> 00:02:45.670
planet that may once have been capable
00:02:45.680 --> 00:02:48.190
of supporting life in fact many
00:02:48.200 --> 00:02:50.149
scientists see Mars as a model for what
00:02:50.159 --> 00:02:52.430
the early Earth might have looked like
00:02:52.440 --> 00:02:54.670
and the lack of plate tectonics on Mars
00:02:54.680 --> 00:02:56.990
means that much of attention geology is
00:02:57.000 --> 00:03:00.149
still in place so by studying Mars we
00:03:00.159 --> 00:03:02.270
learn more about our own home planet as
00:03:02.280 --> 00:03:05.910
well this is spacetime still to come
00:03:05.920 --> 00:03:07.630
could the moon have been created by an
00:03:07.640 --> 00:03:09.670
ejected chunk of the earth and
00:03:09.680 --> 00:03:11.750
establishing a permanent man base on the
00:03:11.760 --> 00:03:14.190
moon how hard could it really be all
00:03:14.200 --> 00:03:19.260
that and more still to come on SpaceTime
00:03:19.270 --> 00:03:32.670
[Music]
00:03:32.680 --> 00:03:34.710
a new study claims that the moon was
00:03:34.720 --> 00:03:37.110
created out of the Earth's mantle the
00:03:37.120 --> 00:03:38.750
findings reported in the journal the
00:03:38.760 --> 00:03:40.030
proceedings of the National Academy of
00:03:40.040 --> 00:03:42.030
Sciences also supports the idea that
00:03:42.040 --> 00:03:43.630
water could have reached the Earth early
00:03:43.640 --> 00:03:45.390
in its development and may not have been
00:03:45.400 --> 00:03:48.550
added later by asteroid or Comet impacts
00:03:48.560 --> 00:03:50.589
evidence from Rock samples brought back
00:03:50.599 --> 00:03:52.949
by the American Apollo man moon missions
00:03:52.959 --> 00:03:55.350
and studies of early Earth geology both
00:03:55.360 --> 00:03:57.589
suggest the best hypothesis to explain
00:03:57.599 --> 00:03:59.830
the birth of Earth's moon 4.5 billion
00:03:59.840 --> 00:04:03.229
years ago was a giant impact now this
00:04:03.239 --> 00:04:05.670
Theory suggests that a mars-sized planet
00:04:05.680 --> 00:04:08.309
named Thea possibly even an earth Trojan
00:04:08.319 --> 00:04:10.509
slammed into the early Proto Earth about
00:04:10.519 --> 00:04:12.630
62 million years after the birth of the
00:04:12.640 --> 00:04:15.990
solar system 4.6 billion years ago the
00:04:16.000 --> 00:04:17.550
timing is based on measurements of
00:04:17.560 --> 00:04:20.670
tungsten Isotopes in lunar Metals this
00:04:20.680 --> 00:04:23.030
Cosmic Collision melted both bodies
00:04:23.040 --> 00:04:25.430
turning the lot into a giant magma ocean
00:04:25.440 --> 00:04:28.430
floating in space Thea's dense iron and
00:04:28.440 --> 00:04:30.510
nickel core coal with without of the
00:04:30.520 --> 00:04:33.230
earth now at the same time vaporized
00:04:33.240 --> 00:04:34.909
debris from the's lighter silicate
00:04:34.919 --> 00:04:36.629
mantle and crust together with material
00:04:36.639 --> 00:04:38.909
from the Earth was ejected into space
00:04:38.919 --> 00:04:40.870
eventually orbiting the Earth as a ring
00:04:40.880 --> 00:04:43.029
before slowly coalescing into the moon
00:04:43.039 --> 00:04:45.830
we see today being composed mostly of
00:04:45.840 --> 00:04:47.990
silicates neatly explains why the moon's
00:04:48.000 --> 00:04:51.110
not as dense as the Earth but now
00:04:51.120 --> 00:04:52.510
researchers have discovered another
00:04:52.520 --> 00:04:54.230
piece of the puzzle of formation of the
00:04:54.240 --> 00:04:56.230
Moon and also how water reached the
00:04:56.240 --> 00:04:58.830
Earth the new measurements indicate that
00:04:58.840 --> 00:05:00.710
the moon formed from Material ejected
00:05:00.720 --> 00:05:02.390
from the Earth's mantle with little
00:05:02.400 --> 00:05:04.830
contribution from Thea the authors
00:05:04.840 --> 00:05:07.350
analyzed oxygen Isotopes from 14 samples
00:05:07.360 --> 00:05:09.510
from the Moon and carried out 191
00:05:09.520 --> 00:05:11.990
measurements on minerals from Earth they
00:05:12.000 --> 00:05:14.110
used an improved version of laser flu
00:05:14.120 --> 00:05:16.430
oration a method in which Oxygen's
00:05:16.440 --> 00:05:18.909
released from Rock using a laser the new
00:05:18.919 --> 00:05:20.990
measurements show a very high similarity
00:05:21.000 --> 00:05:22.550
between samples taken from both the
00:05:22.560 --> 00:05:24.629
Earth and the moon of an isotope called
00:05:24.639 --> 00:05:27.990
oxygen 17 now the isotopic similarity
00:05:28.000 --> 00:05:29.830
between the Earth and Moon is along
00:05:29.840 --> 00:05:31.830
standing problem in cosmochemistry for
00:05:31.840 --> 00:05:34.189
which the term isotope crisis has been
00:05:34.199 --> 00:05:36.430
coined one of the study's authors
00:05:36.440 --> 00:05:39.110
Andreas pack from Gran University says
00:05:39.120 --> 00:05:41.350
one explanation is that Theo lost its
00:05:41.360 --> 00:05:43.550
Rocky mantle in earlier collisions and
00:05:43.560 --> 00:05:45.510
then slammed into the Earth more like a
00:05:45.520 --> 00:05:48.230
giant metallic Cannonball now if this
00:05:48.240 --> 00:05:50.029
were the case Thea would be part of the
00:05:50.039 --> 00:05:52.390
Earth's iron core today and the moon
00:05:52.400 --> 00:05:54.230
would have formed from ejected material
00:05:54.240 --> 00:05:57.029
from the Proto Earth's mantle Pac says
00:05:57.039 --> 00:05:58.670
this would explain the similarity in the
00:05:58.680 --> 00:06:00.990
composition of the Earth and the moon
00:06:01.000 --> 00:06:03.189
and the data obtained also provided an
00:06:03.199 --> 00:06:05.870
Insight in the history of water on Earth
00:06:05.880 --> 00:06:07.510
the widespread assumption is that it
00:06:07.520 --> 00:06:09.070
only arrived on Earth after the
00:06:09.080 --> 00:06:10.670
formation of the Moon most likely
00:06:10.680 --> 00:06:12.510
through a series of asteroid and Comet
00:06:12.520 --> 00:06:15.230
impacts known as the late veneer event
00:06:15.240 --> 00:06:16.430
as the Earth was hit much more
00:06:16.440 --> 00:06:18.469
frequently by these impacts in the moon
00:06:18.479 --> 00:06:19.790
there should also be a measurable
00:06:19.800 --> 00:06:21.830
difference between the oxygen Isotopes
00:06:21.840 --> 00:06:23.710
depending on the origins of the material
00:06:23.720 --> 00:06:26.469
that impacted however since the new data
00:06:26.479 --> 00:06:28.309
shows that this isn't the case many
00:06:28.319 --> 00:06:29.990
types of meteorites can have be ruled
00:06:30.000 --> 00:06:31.629
out as a possible cause for the late
00:06:31.639 --> 00:06:34.230
veneer instead the data can be explained
00:06:34.240 --> 00:06:36.189
by a class of meteorites called inati
00:06:36.199 --> 00:06:38.350
condres which are isotopically similar
00:06:38.360 --> 00:06:40.670
to the Earth and contain enough water to
00:06:40.680 --> 00:06:42.749
be solely responsible for the Earth's
00:06:42.759 --> 00:06:46.430
water formation this is spacetime still
00:06:46.440 --> 00:06:48.670
to come establishing a permanent
00:06:48.680 --> 00:06:50.909
presence on the moon how hard could it
00:06:50.919 --> 00:06:53.309
be and later in the science report a new
00:06:53.319 --> 00:06:55.070
study warns that Coral bleaching on the
00:06:55.080 --> 00:06:56.909
Great Barrier Reef has now reached
00:06:56.919 --> 00:06:59.029
catastrophic levels all that and more
00:06:59.039 --> 00:07:15.230
still to come come on
00:07:15.240 --> 00:07:18.270
SpaceTime nessa's emis program is aimed
00:07:18.280 --> 00:07:20.350
at returning humans to the lunar Surface
00:07:20.360 --> 00:07:21.830
after a break of more than half a
00:07:21.840 --> 00:07:24.070
century and this time maintaining a
00:07:24.080 --> 00:07:26.749
permanent presence there the idea is
00:07:26.759 --> 00:07:28.629
that eventually the moon will provide a
00:07:28.639 --> 00:07:31.070
jumping off point for man missions to
00:07:31.080 --> 00:07:33.670
Mars but building a permanent man base
00:07:33.680 --> 00:07:35.309
on the moon will involve lots of
00:07:35.319 --> 00:07:37.869
planning and lots of innovation
00:07:37.879 --> 00:07:39.550
establishing a Human Habitat on the
00:07:39.560 --> 00:07:41.670
lunar South Pole on an airless Dusty
00:07:41.680 --> 00:07:43.350
radiation soaked Rock thousands of
00:07:43.360 --> 00:07:45.189
kilometers from Earth is doable with
00:07:45.199 --> 00:07:47.230
today's technology but that doesn't mean
00:07:47.240 --> 00:07:49.710
it's going to be easy now a review of
00:07:49.720 --> 00:07:51.670
the plan by Concordia researchers
00:07:51.680 --> 00:07:53.110
reported in the journal progress in
00:07:53.120 --> 00:07:55.230
Aerospace science breaks down the many
00:07:55.240 --> 00:07:57.390
challenges of lunar based manufacturing
00:07:57.400 --> 00:07:59.149
construction which will be essential for
00:07:59.159 --> 00:08:01.110
a establishing a sustainable long-term
00:08:01.120 --> 00:08:03.550
lunar presence to establish the
00:08:03.560 --> 00:08:05.390
infrastructure needed to produce the
00:08:05.400 --> 00:08:07.589
essential tools structures and systems
00:08:07.599 --> 00:08:09.589
habitation on the moon will require
00:08:09.599 --> 00:08:12.350
three critical Technologies firstly
00:08:12.360 --> 00:08:14.029
there's 3D printing then there's
00:08:14.039 --> 00:08:16.510
extensive use of Robotics and finally
00:08:16.520 --> 00:08:18.909
lots of artificial intelligence to solve
00:08:18.919 --> 00:08:21.110
problems in new ways one of the
00:08:21.120 --> 00:08:23.309
studies's authors Kristoph skinski says
00:08:23.319 --> 00:08:25.110
these three Technologies working
00:08:25.120 --> 00:08:26.710
together offer the versatility
00:08:26.720 --> 00:08:28.909
adaptability and flexibility needed to
00:08:28.919 --> 00:08:31.749
respond to the challenges as they arise
00:08:31.759 --> 00:08:33.509
a 3D printer will be able to produce
00:08:33.519 --> 00:08:35.310
specialized parts and structures
00:08:35.320 --> 00:08:37.149
essential to building maintaining and
00:08:37.159 --> 00:08:39.709
repairing lunar infrastructure given the
00:08:39.719 --> 00:08:41.230
unique environment in which they'll be
00:08:41.240 --> 00:08:42.829
used many of the instruments will be
00:08:42.839 --> 00:08:44.870
equally unique in fact for everything
00:08:44.880 --> 00:08:46.470
that needs to be built on the moon it'll
00:08:46.480 --> 00:08:48.350
probably be the first time and it will
00:08:48.360 --> 00:08:50.230
need to be done based either on inputs
00:08:50.240 --> 00:08:51.870
from the crew on site or from
00:08:51.880 --> 00:08:53.790
Specialists on the earth who can beam up
00:08:53.800 --> 00:08:55.710
designs have the machines produce them
00:08:55.720 --> 00:08:57.990
while the astronauts are asleep the moon
00:08:58.000 --> 00:09:00.030
also has a critical natural source that
00:09:00.040 --> 00:09:02.110
can help cut down the total payload from
00:09:02.120 --> 00:09:04.350
Earth launch Supply missions namely the
00:09:04.360 --> 00:09:06.990
lunar regul the layer of fine but highly
00:09:07.000 --> 00:09:09.110
abrasive dust which covers the moon's
00:09:09.120 --> 00:09:11.230
surface and so there'll need to be a
00:09:11.240 --> 00:09:13.750
mobile 3D printing robot that uses a
00:09:13.760 --> 00:09:15.750
composite of space grade polymers known
00:09:15.760 --> 00:09:18.110
as polyether Ketone and a Luna dust
00:09:18.120 --> 00:09:20.269
simulant for on demand fabrication of
00:09:20.279 --> 00:09:23.030
complex geometries and of course regali
00:09:23.040 --> 00:09:24.670
has the additional benefit of being an
00:09:24.680 --> 00:09:26.350
effective barrier against solar
00:09:26.360 --> 00:09:28.910
radiation so using it in construction as
00:09:28.920 --> 00:09:31.269
a radi insulator layer would reduce the
00:09:31.279 --> 00:09:33.230
need to bring similar materials up from
00:09:33.240 --> 00:09:35.990
Earth the longer term challenge will be
00:09:36.000 --> 00:09:37.829
transitioning towards using local
00:09:37.839 --> 00:09:39.829
materials on the moon primarily not just
00:09:39.839 --> 00:09:42.590
as a filler but as the main ingredient
00:09:42.600 --> 00:09:44.310
however current solutions for this are
00:09:44.320 --> 00:09:46.829
all very energy intensive both the
00:09:46.839 --> 00:09:48.670
United States and China have stated
00:09:48.680 --> 00:09:50.710
their Ambitions to establish long-term
00:09:50.720 --> 00:09:52.389
presence on the Moon by the middle of
00:09:52.399 --> 00:09:55.550
the next decade gisi says the goals are
00:09:55.560 --> 00:09:57.150
feasible for similar and shorter
00:09:57.160 --> 00:09:58.870
duration missions along the lines of
00:09:58.880 --> 00:10:00.829
trips to the International Space Station
00:10:00.839 --> 00:10:03.750
or Antarctic research centers he says a
00:10:03.760 --> 00:10:05.750
longer term presence will present even
00:10:05.760 --> 00:10:07.750
more challenges especially regarding the
00:10:07.760 --> 00:10:09.750
effects extended duration has on human
00:10:09.760 --> 00:10:11.870
biology as well as legal issues around
00:10:11.880 --> 00:10:14.430
Luna territorial
00:10:14.440 --> 00:10:15.870
[Music]
00:10:15.880 --> 00:10:18.150
rights one of the challenging things
00:10:18.160 --> 00:10:20.470
about building on the moon is that you
00:10:20.480 --> 00:10:22.949
don't want to bring large infrastructure
00:10:22.959 --> 00:10:25.590
with you and it's also challenging to
00:10:25.600 --> 00:10:28.550
bring humans so ideally what you'd like
00:10:28.560 --> 00:10:31.470
to do is use small robots that can move
00:10:31.480 --> 00:10:34.110
around and do the building successful
00:10:34.120 --> 00:10:36.069
integration of Robotics additive
00:10:36.079 --> 00:10:38.949
manufacturing or 3D printing and AI is
00:10:38.959 --> 00:10:41.590
essential for lunar fabrication robotics
00:10:41.600 --> 00:10:43.829
help us to fabricate large scale Parts
00:10:43.839 --> 00:10:47.030
in harsh environments AI helps us to
00:10:47.040 --> 00:10:49.750
enhance decision making optimize the
00:10:49.760 --> 00:10:53.110
design and monitor the processes working
00:10:53.120 --> 00:10:56.110
on the moon is nasty business because
00:10:56.120 --> 00:10:58.910
you have to deal with the regolith that
00:10:58.920 --> 00:11:00.990
is there you have to deal with the
00:11:01.000 --> 00:11:02.910
temperature fluctuations the harsh
00:11:02.920 --> 00:11:05.069
vacuum environment and the reduced
00:11:05.079 --> 00:11:07.629
gravity and you have to get the
00:11:07.639 --> 00:11:09.470
materials there both your building
00:11:09.480 --> 00:11:11.870
materials and the Machinery to build it
00:11:11.880 --> 00:11:13.910
which is one of the most difficult and
00:11:13.920 --> 00:11:17.030
most expensive challenges lunar regolith
00:11:17.040 --> 00:11:21.150
is a nasty Jagged abrasive material
00:11:21.160 --> 00:11:22.990
which makes it difficult to work with
00:11:23.000 --> 00:11:26.030
and introduces engineering challenges to
00:11:26.040 --> 00:11:29.030
integrate into any process on the other
00:11:29.040 --> 00:11:32.350
hand and using the material is a great
00:11:32.360 --> 00:11:35.590
way to reduce the costs of exploration
00:11:35.600 --> 00:11:37.670
additive manufacturing whether it's on
00:11:37.680 --> 00:11:40.389
the moon or here on Earth is advancing
00:11:40.399 --> 00:11:43.870
rapidly and is enabling us to combine
00:11:43.880 --> 00:11:50.190
high-tech materials in very novel
00:11:50.200 --> 00:11:53.150
ways that's kristofh skiski and Muhammad
00:11:53.160 --> 00:11:55.190
aami from the Concord Institute for
00:11:55.200 --> 00:11:58.470
Aerospace design and Innovation and this
00:11:58.480 --> 00:11:59.840
is spacetime
00:11:59.850 --> 00:12:14.670
[Music]
00:12:14.680 --> 00:12:17.069
time and time now to take another brief
00:12:17.079 --> 00:12:18.430
look at some of the other stories making
00:12:18.440 --> 00:12:20.509
news in science this week with a science
00:12:20.519 --> 00:12:23.269
report a new study has warned that outs
00:12:23.279 --> 00:12:24.750
diagnosed with attention deficit
00:12:24.760 --> 00:12:27.509
hyperactivity disorder or ADHD may have
00:12:27.519 --> 00:12:30.470
shorter lifespans the findings reported
00:12:30.480 --> 00:12:32.430
in the British Journal of Psychiatry and
00:12:32.440 --> 00:12:35.550
Based on data from 3,29 adults across
00:12:35.560 --> 00:12:38.350
the UK who have all been diagnosed with
00:12:38.360 --> 00:12:41.629
ADHD they then compared this group with
00:12:41.639 --> 00:12:44.550
3,390 participants without ADHD who were
00:12:44.560 --> 00:12:47.069
matched by age sex and primary care
00:12:47.079 --> 00:12:49.150
practice the authors has found an
00:12:49.160 --> 00:12:51.189
apparent reduction in life expectancy
00:12:51.199 --> 00:12:53.990
for men with diagnosed ADHD of between 4
00:12:54.000 --> 00:12:56.590
and 1/2 and 9 years and between 6 and
00:12:56.600 --> 00:12:59.189
1/2 and 11 years for women more
00:12:59.199 --> 00:13:01.030
disturbingly the study also found that
00:13:01.040 --> 00:13:03.590
fewer than one in N adults with ADHD had
00:13:03.600 --> 00:13:05.509
actually been diagnosed meaning that
00:13:05.519 --> 00:13:07.310
only a fraction of the total population
00:13:07.320 --> 00:13:10.069
of adults with ADHD could be studied
00:13:10.079 --> 00:13:12.350
people with ADHD experience differences
00:13:12.360 --> 00:13:14.550
in the way they focus their attention
00:13:14.560 --> 00:13:16.150
they often have high energy and an
00:13:16.160 --> 00:13:17.829
ability to focus intensely on what
00:13:17.839 --> 00:13:20.470
interests them however they may find it
00:13:20.480 --> 00:13:22.790
difficult to focus on mundane tasks that
00:13:22.800 --> 00:13:24.389
can lead to more impulsiveness
00:13:24.399 --> 00:13:26.430
restlessness and differences in planning
00:13:26.440 --> 00:13:28.750
and time management and that makes it
00:13:28.760 --> 00:13:31.110
harder to succeed at school or at work
00:13:31.120 --> 00:13:33.509
leading to longer term
00:13:33.519 --> 00:13:35.910
challenges new research warns that the
00:13:35.920 --> 00:13:37.710
cycle of coral bleaching on the Great
00:13:37.720 --> 00:13:39.430
Barrier Reef has now reached
00:13:39.440 --> 00:13:41.949
catastrophic levels the study by
00:13:41.959 --> 00:13:43.790
scientists with the University of Sydney
00:13:43.800 --> 00:13:45.790
highlights the complex interplay between
00:13:45.800 --> 00:13:48.310
heat stress disease onset and coral
00:13:48.320 --> 00:13:51.350
mortality the authors found that 66% of
00:13:51.360 --> 00:13:53.230
the colonies were bleached by February
00:13:53.240 --> 00:13:57.470
2024 and 80% by April last year and by
00:13:57.480 --> 00:14:00.430
July they found that 40 4% of all bleach
00:14:00.440 --> 00:14:02.870
Coral colonies had
00:14:02.880 --> 00:14:05.389
died a new study has found that blue
00:14:05.399 --> 00:14:07.430
rings in the stems of trees and bushes
00:14:07.440 --> 00:14:09.310
in Norway could have been the result of
00:14:09.320 --> 00:14:11.550
volcanic eruptions in Central and South
00:14:11.560 --> 00:14:13.509
America a report in the journal
00:14:13.519 --> 00:14:15.749
Frontiers in plant science studied
00:14:15.759 --> 00:14:18.030
Norwegian pine trees and Juniper shrubs
00:14:18.040 --> 00:14:20.389
dying wood samples to reveal blue Rings
00:14:20.399 --> 00:14:22.189
which represent years when the plant
00:14:22.199 --> 00:14:24.350
didn't grow properly likely due to
00:14:24.360 --> 00:14:26.550
especially cold summer weather the
00:14:26.560 --> 00:14:28.310
authors found that across the plants
00:14:28.320 --> 00:14:30.470
they sampled Rings were most common from
00:14:30.480 --> 00:14:34.749
the years 1902 and 1877 with 96% of
00:14:34.759 --> 00:14:37.110
pines and 68% of juniper shrubs
00:14:37.120 --> 00:14:40.310
revealing blue Rings In 1902 and 84% of
00:14:40.320 --> 00:14:43.350
trees and 36% of shrubs in
00:14:43.360 --> 00:14:45.749
1877 they say previous research had
00:14:45.759 --> 00:14:47.590
already linked the cold 1902
00:14:47.600 --> 00:14:49.350
temperatures in Scandinavia to the
00:14:49.360 --> 00:14:51.310
volcanic eruption of Mount Pelle in the
00:14:51.320 --> 00:14:54.389
Caribbean and the cold summer of 1877
00:14:54.399 --> 00:14:57.829
aligns with the eruption of Cotopaxi in
00:14:57.839 --> 00:15:00.150
Ecuador well it's been a huge week in
00:15:00.160 --> 00:15:02.030
technology with Samsung releasing its
00:15:02.040 --> 00:15:04.550
new AI smartphones with the details
00:15:04.560 --> 00:15:06.269
we're joined by technology editor Alex
00:15:06.279 --> 00:15:09.150
saharov Roy from Tech advice. life yes
00:15:09.160 --> 00:15:11.710
well there's three models the s25 the
00:15:11.720 --> 00:15:15.310
s25 plus and the s25 ultra obviously the
00:15:15.320 --> 00:15:17.470
ultra is the most advanced model with
00:15:17.480 --> 00:15:19.030
the biggest screen and the best cameras
00:15:19.040 --> 00:15:20.829
and The Stylist but all of them have the
00:15:20.839 --> 00:15:24.350
Snapdragon 8 Elite for Galaxy so this is
00:15:24.360 --> 00:15:27.110
a specially fine-tuned processor they're
00:15:27.120 --> 00:15:29.870
talking about a boost of 40 % in the
00:15:29.880 --> 00:15:33.990
neural Processing Unit 37% in the CPU
00:15:34.000 --> 00:15:37.670
and 30% in the GPU compared to the s24
00:15:37.680 --> 00:15:40.230
generation and what Samsung is doing is
00:15:40.240 --> 00:15:42.829
they're promoting this as your AI
00:15:42.839 --> 00:15:44.870
companion so I've seen this phone of
00:15:44.880 --> 00:15:46.509
played with it at a special event for
00:15:46.519 --> 00:15:48.990
the media and you can talk to the phone
00:15:49.000 --> 00:15:50.670
like it was a human it's using Google
00:15:50.680 --> 00:15:53.350
Gemini so Bixby which was Samsung's
00:15:53.360 --> 00:15:55.189
previous AI system it's still there but
00:15:55.199 --> 00:15:57.710
it's no longer the prime AI companion
00:15:57.720 --> 00:15:59.749
it's now Gemini and you can talk to
00:15:59.759 --> 00:16:01.269
Gemini in the same way you can talk to
00:16:01.279 --> 00:16:04.230
chat GPT and discuss ideas and issues
00:16:04.240 --> 00:16:06.949
and reason with it so that puts it ahead
00:16:06.959 --> 00:16:09.069
of what apple is doing it brings it to
00:16:09.079 --> 00:16:10.430
par with what Google is doing because
00:16:10.440 --> 00:16:12.110
Google has had Gemini and look existing
00:16:12.120 --> 00:16:13.910
users can download Gemini and use it too
00:16:13.920 --> 00:16:15.990
but this is now sort of a standard part
00:16:16.000 --> 00:16:18.470
of the phone you can ask your phone to
00:16:18.480 --> 00:16:20.550
look at a YouTube video uh extract
00:16:20.560 --> 00:16:22.230
whatever are the main points and put it
00:16:22.240 --> 00:16:24.550
into a note in your notes app for you so
00:16:24.560 --> 00:16:26.110
the whole idea is it's becoming this
00:16:26.120 --> 00:16:29.590
agentic AI device where you can interact
00:16:29.600 --> 00:16:31.590
with your phone and get it to do things
00:16:31.600 --> 00:16:33.550
across different apps now at the moment
00:16:33.560 --> 00:16:35.590
it's the apps that are built in the
00:16:35.600 --> 00:16:38.030
calendar the Gmail Spotify and WhatsApp
00:16:38.040 --> 00:16:39.150
or a couple of app I mean there'll be
00:16:39.160 --> 00:16:41.030
more of them to come but there's a I
00:16:41.040 --> 00:16:43.269
think called now brief that shows you
00:16:43.279 --> 00:16:44.870
information on you know when you have to
00:16:44.880 --> 00:16:46.470
leave for your next appointment or
00:16:46.480 --> 00:16:47.870
things that you have scheduled for the
00:16:47.880 --> 00:16:49.110
rest of the day other interesting
00:16:49.120 --> 00:16:51.230
information that is like a briefing for
00:16:51.240 --> 00:16:52.629
you and you have this when you look at
00:16:52.639 --> 00:16:54.030
the phone it's on the lock screen as
00:16:54.040 --> 00:16:55.870
well uh you've got call recording and
00:16:55.880 --> 00:16:57.629
transcripts you've got the ability to
00:16:57.639 --> 00:16:59.629
translate 20 different languages on
00:16:59.639 --> 00:17:02.269
device Samsung has been very strong in
00:17:02.279 --> 00:17:04.110
in pointing out how much it's taking
00:17:04.120 --> 00:17:06.549
privacy very seriously being able to
00:17:06.559 --> 00:17:08.590
interact with the phone to ask it to dim
00:17:08.600 --> 00:17:10.429
the screen because your eyes are tired
00:17:10.439 --> 00:17:11.829
it's something you can now do just by
00:17:11.839 --> 00:17:13.429
asking there's a feature called best
00:17:13.439 --> 00:17:15.710
face a little bit similar to one we saw
00:17:15.720 --> 00:17:17.829
from Google last year where you can take
00:17:17.839 --> 00:17:20.870
a series of photos of you know people at
00:17:20.880 --> 00:17:22.549
a party or at an event and inevitably
00:17:22.559 --> 00:17:24.069
somebody is going to be blinking or
00:17:24.079 --> 00:17:26.189
looking away or not smiling and you can
00:17:26.199 --> 00:17:28.029
now choose from all the the right faces
00:17:28.039 --> 00:17:29.510
and choose the best one so everyone
00:17:29.520 --> 00:17:31.270
looks their best and I asked Samsung is
00:17:31.280 --> 00:17:32.789
this just Google's feature or is this
00:17:32.799 --> 00:17:34.350
your own and they said it's their own
00:17:34.360 --> 00:17:35.789
feature which is interesting because
00:17:35.799 --> 00:17:37.390
good for competition there's an audio
00:17:37.400 --> 00:17:39.070
eraser so let's say you're recording a
00:17:39.080 --> 00:17:40.909
video and there's wind noise or there's
00:17:40.919 --> 00:17:42.510
just too much background noise or you're
00:17:42.520 --> 00:17:44.110
at the beach and there's noise from the
00:17:44.120 --> 00:17:46.390
you know the ocean you can actually turn
00:17:46.400 --> 00:17:48.510
various elements of the background noise
00:17:48.520 --> 00:17:50.950
up or down so you can focus on The Voice
00:17:50.960 --> 00:17:53.710
or you can focus on the uh the noises of
00:17:53.720 --> 00:17:55.630
nature so that's giving you some video
00:17:55.640 --> 00:17:57.350
editing capabilities if you have a bunch
00:17:57.360 --> 00:17:59.350
of Samsung appliances like one of their
00:17:59.360 --> 00:18:01.909
watches and a TV maybe air filters the
00:18:01.919 --> 00:18:03.630
watch can figure out when it is you
00:18:03.640 --> 00:18:05.230
falling asleep because your breathing
00:18:05.240 --> 00:18:06.909
patterns change and other things change
00:18:06.919 --> 00:18:08.830
and it can turn the TV off for you or it
00:18:08.840 --> 00:18:12.029
can put on the uh air purifier if it
00:18:12.039 --> 00:18:13.310
needs to do that based on what it's
00:18:13.320 --> 00:18:15.270
figuring out about your personal health
00:18:15.280 --> 00:18:16.870
metrics the other big question of course
00:18:16.880 --> 00:18:18.750
is price I understand they've gone down
00:18:18.760 --> 00:18:20.270
in price compared to previous models
00:18:20.280 --> 00:18:21.510
yeah well a few things have gone down so
00:18:21.520 --> 00:18:23.789
it's thinner it's lighter it's stronger
00:18:23.799 --> 00:18:26.950
uh with this uh Corning Gorilla Glass to
00:18:26.960 --> 00:18:28.350
now last time you could drop it from
00:18:28.360 --> 00:18:30.270
waste he to a meter this time you could
00:18:30.280 --> 00:18:33.230
drop it from head height 2.2 m without a
00:18:33.240 --> 00:18:35.149
case and according to the test the
00:18:35.159 --> 00:18:38.070
screen hasn't broken now the s25 ultra
00:18:38.080 --> 00:18:40.630
starts for the 256 gig model in
00:18:40.640 --> 00:18:42.270
Australian dollars at
00:18:42.280 --> 00:18:45.070
$2,149 so that's 50 bucks less than last
00:18:45.080 --> 00:18:47.430
year and they've also got a 512 gig and
00:18:47.440 --> 00:18:50.990
a 1 TB model it's 2349 for the 512 and
00:18:51.000 --> 00:18:54.110
2749 for the 1 terab obviously the s25
00:18:54.120 --> 00:18:56.230
and the s25 plus are cheaper with
00:18:56.240 --> 00:18:59.029
smaller screens but usually the ult is
00:18:59.039 --> 00:19:00.549
the particular one that they want to
00:19:00.559 --> 00:19:02.909
sell they teased something else it was
00:19:02.919 --> 00:19:05.470
called the Samsung s25 Edge so this is a
00:19:05.480 --> 00:19:07.430
very thin phone meant to compete with
00:19:07.440 --> 00:19:10.070
the rumored iPhone 17 air that's meant
00:19:10.080 --> 00:19:12.070
to come in September or October this
00:19:12.080 --> 00:19:13.590
year from Apple they've just gone all
00:19:13.600 --> 00:19:15.669
out to make this the best Android phone
00:19:15.679 --> 00:19:16.990
you can get even better than the ones
00:19:17.000 --> 00:19:19.110
from Google and they're hoping that this
00:19:19.120 --> 00:19:21.029
is going to propel them into winning the
00:19:21.039 --> 00:19:23.909
