SpaceTime Series 27 Episode 128
*Dating the Moon's Oldest Impact Crater
Scientists have pinpointed the edge of the massive South Pole-Aitken Basin, the largest and oldest known impact crater on the Moon, dating it to over 4.32 billion years old. By analysing a lunar meteorite, researchers have concluded that this impact site is around 120 million years earlier than the previously believed intense period of impact bombardment. These findings provide a clearer picture of the Moon's early impact history and have implications for understanding Earth's early conditions.
*Recreating the Sound of Earth's Magnetic Polar Flip
With evidence suggesting that Earth's magnetic poles are about to flip, scientists have recreated what they believe could be the sound of this event. Earth's magnetic field, vital for life, is generated by the planet's molten outer core. The recreated soundscape provides an audio insight into the geomagnetic reversals, which occur roughly every 250,000 years, with the last flip occurring 770,000 years ago.
*X-37B Space Shuttle's Pioneering Aero Braking Manoeuvre
The United States Space Force's X-37B Space shuttle has completed a novel aero braking manoeuvre to adjust its orbital flight path. This technique allows the spacecraft to safely eject service module components, preventing them from becoming Space junk. The operation marks a first for the X-37B, which continues its classified missions involving radiation experiments and space domain awareness technology testing.

00:00:03 --> 00:00:06 for broadcast on the 23rd of October
00:00:06 --> 00:00:09 2024 coming up on space Time dating the
00:00:09 --> 00:00:12 moon's oldest impact crater scientists
00:00:12 --> 00:00:14 recreate the sound of the Earth's
00:00:14 --> 00:00:17 magnetic polar flip and the X-37B space
00:00:17 --> 00:00:19 shuttle undertakes a pioneering aror
00:00:19 --> 00:00:22 breaking maneuver all that and more
00:00:22 --> 00:00:24 coming up on
00:00:24 --> 00:00:27 SpaceTime welcome to SpaceTime with
00:00:27 --> 00:00:29 Stuart Gary
00:00:29 --> 00:00:36 [Music]
00:00:44 --> 00:00:46 scientists believe they've pinpointed
00:00:46 --> 00:00:48 the edge of the massive South Pole Aken
00:00:48 --> 00:00:50 Basin the largest and oldest known
00:00:50 --> 00:00:53 impact crator on the moon determining
00:00:53 --> 00:00:56 that it's over 4.32 billion years old
00:00:56 --> 00:00:58 the moon like the Earth has been
00:00:58 --> 00:01:00 bombarded by a asteroids and comets
00:01:00 --> 00:01:03 since its formation 4.5 billion years
00:01:03 --> 00:01:06 ago leaving behind a history of craters
00:01:06 --> 00:01:09 and basins however the exact timing and
00:01:09 --> 00:01:11 intensity of most of these events
00:01:11 --> 00:01:13 including the more than 2 kmet wide
00:01:13 --> 00:01:15 South Pole Aken Basin have remained
00:01:15 --> 00:01:19 unclear until now however by analyzing a
00:01:19 --> 00:01:21 Luna meteorite known as northwest Africa
00:01:21 --> 00:01:24 2995 scientists have concluded that the
00:01:24 --> 00:01:26 moon's oldest confirmed impact site is
00:01:26 --> 00:01:29 around 120 million years earlier than
00:01:29 --> 00:01:31 what's believed to be the most intense
00:01:31 --> 00:01:33 period of impact bombardment on the moon
00:01:34 --> 00:01:35 the new findings reported in the journal
00:01:35 --> 00:01:38 Nature astronomy provide a far clearer
00:01:38 --> 00:01:40 picture of the moon's early impact
00:01:40 --> 00:01:42 history one of the study's authors
00:01:42 --> 00:01:44 Joshua Snape from the University of
00:01:44 --> 00:01:45 Manchester says scientist have been
00:01:45 --> 00:01:47 studying rocks collected during the
00:01:47 --> 00:01:49 Apollo lunar and changy 5 missions as
00:01:50 --> 00:01:51 well as lunar meteorites that have
00:01:51 --> 00:01:53 reached the Earth slowly building up a
00:01:53 --> 00:01:55 picture of when these impact events
00:01:55 --> 00:01:58 occurred for several decades there's
00:01:58 --> 00:02:00 been General agreement that the most
00:02:00 --> 00:02:02 intense impact period known as the late
00:02:02 --> 00:02:04 heavy bombardment was concentrated
00:02:04 --> 00:02:07 between 4.2 and 3.8 billion years ago
00:02:07 --> 00:02:09 during the first half billion years of
00:02:09 --> 00:02:12 the moon's history but now constraining
00:02:12 --> 00:02:14 the age of the South Pole aen Bas into
00:02:14 --> 00:02:16 120 million years earlier weakens that
00:02:16 --> 00:02:18 argument for this narrow period of
00:02:18 --> 00:02:20 impact bombardment on the moon and
00:02:20 --> 00:02:22 instead indicates there was a far more
00:02:23 --> 00:02:25 gradual process of impact over a longer
00:02:25 --> 00:02:28 period the northwest Africa 2995
00:02:28 --> 00:02:31 meteorite was found in Algeria in
00:02:31 --> 00:02:34 2005 it's what geologists refer to as
00:02:34 --> 00:02:36 regolith breia which means it contains
00:02:36 --> 00:02:38 fragments of different rock types that
00:02:38 --> 00:02:40 were once lunar soil and which were
00:02:40 --> 00:02:42 fused together by the heat and pressure
00:02:42 --> 00:02:45 involved in an impact event during this
00:02:45 --> 00:02:46 event there were flung off the moon
00:02:46 --> 00:02:49 surface as ejected debris eventually
00:02:49 --> 00:02:51 making their way to Earth by analyzing
00:02:51 --> 00:02:54 the amount of uranium and lid found in a
00:02:54 --> 00:02:55 range of minerals and rock fragments
00:02:55 --> 00:02:57 from this meteorite the authors were
00:02:57 --> 00:02:59 able to determine the materials date
00:02:59 --> 00:03:03 back between 4.32 and 4.33 billion years
00:03:03 --> 00:03:05 ago the team then compared the results
00:03:05 --> 00:03:07 to data collected by NASA's lunar
00:03:07 --> 00:03:09 prospector Mission which orbited the
00:03:09 --> 00:03:11 moon studying its surface composition in
00:03:11 --> 00:03:15 1998 and 99 this comparison revealed
00:03:15 --> 00:03:17 many chemical similarities between the
00:03:17 --> 00:03:19 meteorite and the Rocks within the South
00:03:19 --> 00:03:22 Pole Aken Basin confirming their link
00:03:22 --> 00:03:24 and enabling the new age estimate now
00:03:24 --> 00:03:26 these new findings also have
00:03:26 --> 00:03:28 implications reaching far beyond the
00:03:28 --> 00:03:30 moon we know both the Earth and the moon
00:03:30 --> 00:03:32 experienced similar impact events during
00:03:32 --> 00:03:35 their early history problem is most of
00:03:35 --> 00:03:36 the early rock records on earth have
00:03:36 --> 00:03:38 been lost through a combination of
00:03:38 --> 00:03:41 erosion and plate tectonics so
00:03:41 --> 00:03:42 scientists can use what they learned
00:03:42 --> 00:03:44 about the moon to provide clues about
00:03:44 --> 00:03:46 the conditions on Earth during the same
00:03:46 --> 00:03:49 period of course the proposed 4.32
00:03:49 --> 00:03:51 billion year old age of the South Pole
00:03:51 --> 00:03:53 aen Basin now needs to be tested by a
00:03:53 --> 00:03:56 new sample return Mission collecting
00:03:56 --> 00:03:58 rocks from known localities within the
00:03:58 --> 00:04:00 crater itself and that will be one of
00:04:00 --> 00:04:02 the Prime tasks of the emus 3 mission
00:04:02 --> 00:04:06 sled for launch to the lunar surface in
00:04:06 --> 00:04:09 2026 needless to say will keep you
00:04:09 --> 00:04:13 informed this is spacetime still to come
00:04:13 --> 00:04:15 scientists recreate what they think
00:04:15 --> 00:04:17 could be the sound of Earth's magnetic
00:04:17 --> 00:04:20 polar flip and the X-37B space shuttle
00:04:20 --> 00:04:22 undertakes a pioneering aob braing
00:04:22 --> 00:04:25 maneuver all that and more still to come
00:04:25 --> 00:04:28 on SpaceTime
00:04:28 --> 00:04:42 [Music]
00:04:42 --> 00:04:44 with growing evidence that the Earth's
00:04:44 --> 00:04:45 magnetic poles are about to flip
00:04:45 --> 00:04:48 scientists have recreated the sound of
00:04:48 --> 00:04:50 an earth magnetic flip the Earth's
00:04:50 --> 00:04:53 magnetic field is vital for life on our
00:04:53 --> 00:04:56 planet it acts like a shield protecting
00:04:56 --> 00:04:58 us from the worst effects of the solar
00:04:58 --> 00:05:01 wind and intergalactic cosm MC Rays
00:05:01 --> 00:05:03 these polarity reversals occur roughly
00:05:03 --> 00:05:07 every 250 years however the last
00:05:07 --> 00:05:10 flip was some 770 years ago so we're
00:05:10 --> 00:05:12 willing truly overdue for the next and
00:05:12 --> 00:05:14 when it does happen it'll be the first
00:05:14 --> 00:05:16 magnetic field polarity reversal in
00:05:16 --> 00:05:19 Modern Times And that raises some
00:05:19 --> 00:05:21 serious questions about how our
00:05:21 --> 00:05:23 technology will cope with the change the
00:05:23 --> 00:05:25 earth magnetic field seems steady and
00:05:26 --> 00:05:29 true it's reliable enough to navigate by
00:05:29 --> 00:05:31 yet like naturally hidden from daily
00:05:31 --> 00:05:33 life the magnetic field actually drifts
00:05:33 --> 00:05:36 waxes and waines quite considerably in
00:05:36 --> 00:05:37 fact the Magnetic North Pole is
00:05:37 --> 00:05:39 currently careering towards Siberia
00:05:40 --> 00:05:41 which recently forced the global
00:05:41 --> 00:05:43 positioning system that underlies modern
00:05:43 --> 00:05:45 navigation to upgrade its software
00:05:45 --> 00:05:47 sooner than expected in order to account
00:05:47 --> 00:05:51 for the shift but every roughly 250
00:05:51 --> 00:05:53 years or so the magnetic field
00:05:53 --> 00:05:55 dramatically shifts and reverses its
00:05:55 --> 00:05:57 polarity completely in other words the
00:05:57 --> 00:05:59 Magnetic North Pole will shift to the
00:05:59 --> 00:06:01 geog graphic South Pole and the Magnetic
00:06:01 --> 00:06:03 South Pole will shift to the geographic
00:06:03 --> 00:06:05 North the reversals have happened
00:06:05 --> 00:06:08 countless times over Earth's history but
00:06:08 --> 00:06:10 scientists really only have a limited
00:06:10 --> 00:06:11 understanding of why the field reverses
00:06:11 --> 00:06:14 and exactly how it happens we know that
00:06:14 --> 00:06:16 Earth's magnetic field is produced by
00:06:16 --> 00:06:18 the planet's molten liquid outer core as
00:06:18 --> 00:06:20 it spins around the solid iron inner
00:06:20 --> 00:06:22 core generating powerful geomagnetic
00:06:22 --> 00:06:24 currents through what's called a
00:06:24 --> 00:06:27 geodynamo effect this geodynamo creates
00:06:27 --> 00:06:29 a magnetic field that's mostly table
00:06:30 --> 00:06:31 going through roughly the geographic
00:06:31 --> 00:06:34 North and South Poles but the field
00:06:34 --> 00:06:36 shifts and weakens significantly during
00:06:36 --> 00:06:38 Pole reversals now we know this happens
00:06:38 --> 00:06:41 because as new rocks form typically
00:06:41 --> 00:06:43 either as volcanic lava flows or
00:06:43 --> 00:06:44 sediments being deposited on the seaf
00:06:44 --> 00:06:46 Flor they record the magnetic field at
00:06:46 --> 00:06:49 the time they were created so geologists
00:06:49 --> 00:06:51 can survey this geological record and
00:06:51 --> 00:06:53 piece together the history of magnetic
00:06:53 --> 00:06:56 fields going back millions of years but
00:06:56 --> 00:06:59 approximately 41 years ago the earth
00:06:59 --> 00:07:01 magnetic field briefly reversed during
00:07:01 --> 00:07:03 what's known as the last champ event
00:07:03 --> 00:07:05 during this time the Earth magnetic
00:07:05 --> 00:07:07 field weakened significantly dropping to
00:07:07 --> 00:07:10 a minimum of just 5% its current
00:07:10 --> 00:07:12 strength that allowed more Cosmic race
00:07:12 --> 00:07:14 to reach the planet's surface now
00:07:15 --> 00:07:16 scientists from the Technical University
00:07:16 --> 00:07:18 of Denmark and the German Research
00:07:18 --> 00:07:20 Center have used data from the European
00:07:20 --> 00:07:22 Space Agency swarm spacecraft to
00:07:22 --> 00:07:25 recreate a sounded visualization of that
00:07:25 --> 00:07:27 event the data from EA swarm
00:07:27 --> 00:07:29 constellation is used to better
00:07:29 --> 00:07:31 understand how Earth's magnetic fields
00:07:31 --> 00:07:33 generated the satellites measure
00:07:33 --> 00:07:35 magnetic signals not only from the core
00:07:35 --> 00:07:37 but also from the mantle the crust the
00:07:37 --> 00:07:39 oceans and up out into the ionosphere
00:07:39 --> 00:07:42 and magnetosphere these data are crucial
00:07:42 --> 00:07:44 for studying phenoma such as geomagnetic
00:07:44 --> 00:07:46 reversals and the Earth's internal
00:07:46 --> 00:07:49 Dynamics and scientists use that to
00:07:49 --> 00:07:53 generate this stereo sound version
00:07:53 --> 00:08:27 [Music]
00:08:27 --> 00:08:29 the soundscape was actually made use
00:08:29 --> 00:08:31 recordings of natural noises like wood
00:08:31 --> 00:08:33 creaking and rocks falling apart
00:08:33 --> 00:08:35 blending them into familiar and strange
00:08:35 --> 00:08:38 almost alien-like sounds the process of
00:08:38 --> 00:08:40 transforming the sounds with data is
00:08:40 --> 00:08:42 similar to composing music for a score
00:08:43 --> 00:08:45 and it provides a fascinating audio
00:08:45 --> 00:08:48 Insight now as to planet Earth's next
00:08:48 --> 00:08:50 magnetic pole reversal well scientists
00:08:50 --> 00:08:52 believe they may be seeing the early
00:08:52 --> 00:08:53 signs of a significant change in the
00:08:54 --> 00:08:56 planet's magnetic field now right now
00:08:56 --> 00:08:58 there are regions of the earth including
00:08:58 --> 00:09:00 parts of the South Atlantic ocean where
00:09:00 --> 00:09:02 Compass needles simply go nuts pointing
00:09:02 --> 00:09:05 South instead of North this region known
00:09:05 --> 00:09:07 as the South Atlantic anomaly causes
00:09:07 --> 00:09:09 Earth's inner Van Allen radiation built
00:09:09 --> 00:09:11 to move to its closest position towards
00:09:11 --> 00:09:13 the Earth's surface dipping down to an
00:09:13 --> 00:09:16 altitude of just 200 km this results in
00:09:16 --> 00:09:18 an increased flux of energetic particles
00:09:18 --> 00:09:20 in this region which exposes orbiting
00:09:20 --> 00:09:22 satellites to higher than usual levels
00:09:22 --> 00:09:25 of radiation now since its initial
00:09:25 --> 00:09:27 Discovery in 1958 the southern limits of
00:09:27 --> 00:09:29 the South Atlantic anomaly have remained
00:09:29 --> 00:09:32 roughly consistent however a long-term
00:09:32 --> 00:09:33 expansion has been measured to the
00:09:33 --> 00:09:36 Northwest the north the Northeast and
00:09:36 --> 00:09:38 the east as the geomagnetic field
00:09:38 --> 00:09:40 continues to weaken the inner Van Allen
00:09:40 --> 00:09:42 belt gets closer to the Earth with a
00:09:42 --> 00:09:44 commensurate enlargement of the South
00:09:44 --> 00:09:47 Atlantic anomaly at given altitudes and
00:09:47 --> 00:09:49 it's not just an interesting Quirk of
00:09:49 --> 00:09:51 nature the South Atlantic anomaly is of
00:09:51 --> 00:09:53 great significance to astronomical
00:09:53 --> 00:09:55 satellites and other spacecraft that
00:09:55 --> 00:09:57 orbit the planet at several hundred
00:09:57 --> 00:10:00 kilom in altitude these take satellites
00:10:00 --> 00:10:01 through the anomaly periodically
00:10:02 --> 00:10:03 exposing them to several minutes of
00:10:03 --> 00:10:05 strong radiation caused by the Trap
00:10:05 --> 00:10:08 protons in the inner van Alum build
00:10:08 --> 00:10:10 NASA's also reported that laptops have
00:10:10 --> 00:10:12 crashed when spacecraft passed through
00:10:12 --> 00:10:14 the anomaly the International Space
00:10:14 --> 00:10:15 Station which orbits at an inclination
00:10:15 --> 00:10:19 of 51.6 De requires additional shielding
00:10:19 --> 00:10:21 to deal with this problem and the Hubble
00:10:21 --> 00:10:23 Space Telescope does not take
00:10:23 --> 00:10:25 observations while passing through the
00:10:25 --> 00:10:27 anomaly and astronauts are also affected
00:10:27 --> 00:10:30 by this region they see what can be best
00:10:30 --> 00:10:33 described as shooting stars in their
00:10:33 --> 00:10:35 visual field the effects actually caused
00:10:35 --> 00:10:37 by cosmic rays and other charge
00:10:37 --> 00:10:39 particles passing through their eyeballs
00:10:39 --> 00:10:41 as far as we know they don't do much
00:10:41 --> 00:10:43 damage but for the astronaut they appear
00:10:43 --> 00:10:45 as a sudden flash of light in their

00:11:22 --> 00:11:24 Force's X-37B space shuttle has just
00:11:24 --> 00:11:26 completed a novel Arrow breaking
00:11:26 --> 00:11:28 maneuver designed to adjust its orbital
00:11:28 --> 00:11:30 flight path around the earth the
00:11:30 --> 00:11:32 operation allowed the spacecraft to
00:11:32 --> 00:11:34 safely eject its service module
00:11:34 --> 00:11:36 components so as to avoid creating more
00:11:36 --> 00:11:39 space junk this is the first time the
00:11:39 --> 00:11:42 x37 BS employed a dynamic Arrow braing
00:11:42 --> 00:11:44 maneuver Arrow breaking involves using
00:11:44 --> 00:11:46 the drag of the Earth's upper atmosphere
00:11:46 --> 00:11:48 to alter the spacecraft's orbit while
00:11:48 --> 00:11:51 conserving fuel using this maneuver to
00:11:51 --> 00:11:53 eject the service module meant that
00:11:53 --> 00:11:55 instead of floating around in space for
00:11:55 --> 00:11:57 years a space junk the module will
00:11:57 --> 00:11:58 quickly descend into the Earth's
00:11:58 --> 00:12:01 atmosphere where it will burn up
00:12:01 --> 00:12:03 following the maneuver the X-37B
00:12:03 --> 00:12:05 returned to its ongoing experiments
00:12:05 --> 00:12:07 which follow on from six previously
00:12:07 --> 00:12:09 successful and equally secretive
00:12:09 --> 00:12:11 missions the wing space plane was
00:12:11 --> 00:12:12 launched on its current classified
00:12:12 --> 00:12:14 flight back in December the 28th last
00:12:14 --> 00:12:17 year now officially the US space force
00:12:17 --> 00:12:19 is saying the rocket ples involved in
00:12:19 --> 00:12:21 radiation experiments and what they're
00:12:21 --> 00:12:23 calling space domain awareness
00:12:23 --> 00:12:25 technology testing now we know that
00:12:25 --> 00:12:27 means it's performing the functions of
00:12:27 --> 00:12:29 an inspector satellite flying close to
00:12:29 --> 00:12:31 other satellites to study them to see
00:12:31 --> 00:12:33 what they're up to following its launch
00:12:33 --> 00:12:35 it was initially placed in a highly
00:12:35 --> 00:12:37 elliptical orbit but that's been changed
00:12:37 --> 00:12:39 multiple times depending on what else
00:12:39 --> 00:12:41 it's doing and that's the key to the
00:12:41 --> 00:12:45 X-37B success being able to constantly
00:12:45 --> 00:12:47 change its orbit means anyone tracking
00:12:47 --> 00:12:49 it won't know exactly where it is once
00:12:49 --> 00:12:51 it comes back from its apery or most
00:12:51 --> 00:12:53 distant orbital position it means that
00:12:53 --> 00:12:56 every time it reaches orbital Pary those
00:12:56 --> 00:12:57 trying to track it to see what it's up
00:12:57 --> 00:12:59 to need to search the entire is solist
00:12:59 --> 00:13:02 feere to try and find it again
00:13:02 --> 00:13:04 originally developed by NASA and Boeing
00:13:04 --> 00:13:07 in 1999 the x37 as it was then called
00:13:07 --> 00:13:08 was designed to be launched from the
00:13:08 --> 00:13:11 payload Bay of the Space Shuttle however
00:13:11 --> 00:13:13 the program was taken over by the US Air
00:13:13 --> 00:13:16 Force in 2004 and two modified versions
00:13:16 --> 00:13:19 of the original x37 were built they were
00:13:19 --> 00:13:21 then transferred to the newly formed us
00:13:21 --> 00:13:23 space force in
00:13:23 --> 00:13:26 2010 this is spacetime
00:13:26 --> 00:13:41 [Music]
00:13:41 --> 00:13:43 and time now to take another brief look
00:13:43 --> 00:13:45 at some of the other stories making news
00:13:45 --> 00:13:47 in science this week with a science
00:13:47 --> 00:13:49 report a new study has found that deaths
00:13:49 --> 00:13:52 tend to increase in the days immediately
00:13:52 --> 00:13:55 after an extreme rain event the findings
00:13:55 --> 00:13:57 reported in the British medical journal
00:13:57 --> 00:13:58 are based on a study of death and
00:13:58 --> 00:14:01 rainfor data across 34 countries
00:14:01 --> 00:14:03 scientists looked at extreme rainfall
00:14:03 --> 00:14:05 that would usually occur only once or
00:14:05 --> 00:14:08 twice every year once every 2 years and
00:14:08 --> 00:14:11 once every 5 years they found that in
00:14:11 --> 00:14:13 the 2 weeks after a one in fiveyear
00:14:13 --> 00:14:15 event deaths from any cause increased by
00:14:15 --> 00:14:18 8% heart related deaths increased by 5%
00:14:18 --> 00:14:20 and respiratory deaths by
00:14:20 --> 00:14:23 29% only respiratory deaths increased
00:14:23 --> 00:14:25 after a one and 2year event and there
00:14:25 --> 00:14:27 was no change for one-year events the
00:14:27 --> 00:14:29 authors speculate there could be various
00:14:29 --> 00:14:31 reasons why this is happening including
00:14:31 --> 00:14:33 reduced Access to Health Care increased
00:14:33 --> 00:14:35 Airborne water and foodborn disease
00:14:35 --> 00:14:37 risks from increased humidity and
00:14:37 --> 00:14:39 increased anxiety in fact we could be
00:14:39 --> 00:14:41 seeing this in the increase in asthma
00:14:41 --> 00:14:43 related cases during thunderstorms
00:14:44 --> 00:14:47 recorded in Victoria as climate change
00:14:47 --> 00:14:49 sees extreme rainfall events increase
00:14:49 --> 00:14:51 the authors say we should be aware of
00:14:51 --> 00:14:53 the potential flow and
00:14:53 --> 00:14:57 effect a major review of data from nine
00:14:57 --> 00:14:59 studies has taken a close look at at
00:14:59 --> 00:15:01 health effects from Mediterranean style
00:15:01 --> 00:15:03 diets on young people scientists
00:15:03 --> 00:15:06 reanalyzed data on 557 people aged
00:15:06 --> 00:15:08 between 3 and 18 focusing on the
00:15:08 --> 00:15:10 benefits of sticking to a Mediterranean
00:15:10 --> 00:15:12 style diet for heart health and
00:15:12 --> 00:15:14 cholesterol levels a report in the
00:15:14 --> 00:15:16 Journal of the American Medical
00:15:16 --> 00:15:17 Association confirmed that a
00:15:17 --> 00:15:20 Mediterranean diet high in vegetables
00:15:20 --> 00:15:22 and olive oil and low in red and
00:15:22 --> 00:15:24 processed Meats was linked to lower
00:15:24 --> 00:15:26 blood pressure and lower levels of low
00:15:26 --> 00:15:28 density lipoproteins the so-called bad
00:15:28 --> 00:15:30 cholesterol ol as well as increased
00:15:30 --> 00:15:32 levels of high density lipoproteins or
00:15:32 --> 00:15:34 good cholesterol the authors say that
00:15:35 --> 00:15:36 introducing kids to a Mediterranean
00:15:36 --> 00:15:39 style diet could help improve their
00:15:39 --> 00:15:42 health and set them up for healthy adult
00:15:42 --> 00:15:45 lives Engineers have invented new energy
00:15:46 --> 00:15:48 efficient bricks using scrap materials
00:15:48 --> 00:15:50 including glass that are normally
00:15:50 --> 00:15:53 destined for landfill rmit University
00:15:53 --> 00:15:55 Engineers collaborated with vizy
00:15:55 --> 00:15:57 Australia's largest recycling company to
00:15:57 --> 00:16:00 make bricks with a minimum of 15% waste
00:16:00 --> 00:16:03 glass and 20% combusted Solid Waste or
00:16:03 --> 00:16:06 Ash as substitutes for clay a report in
00:16:06 --> 00:16:07 the journal Construction and building
00:16:07 --> 00:16:10 materials claims that tests have shown
00:16:10 --> 00:16:11 that the use of these bricks at the
00:16:11 --> 00:16:13 construction of a single story building
00:16:13 --> 00:16:15 could reduce household energy builds by
00:16:15 --> 00:16:18 up to 5% compared to regular bricks due
00:16:18 --> 00:16:19 to their improved
00:16:19 --> 00:16:22 insulation replacing clay with waste
00:16:22 --> 00:16:24 materials in the brick production help
00:16:24 --> 00:16:25 reduce the firing temperature by up to
00:16:25 --> 00:16:28 20% compared to standard brick mixtures
00:16:28 --> 00:16:30 there thereby offering potential cost
00:16:30 --> 00:16:32 savings to manufacturers as well around
00:16:32 --> 00:16:35 1.4 trillion bricks are used in
00:16:35 --> 00:16:38 construction projects globally each year
00:16:38 --> 00:16:40 the problem is business's usual brick
00:16:40 --> 00:16:42 production produces harmful emissions
00:16:42 --> 00:16:45 including carbon dioxide sulfur dioxide
00:16:45 --> 00:16:47 and chlorine and puts a serious strain
00:16:47 --> 00:16:50 on natural resources especially clay the
00:16:50 --> 00:16:52 authors showed that these new bricks
00:16:52 --> 00:16:54 have enhanced Energy Efficiency through
00:16:54 --> 00:16:56 improved thermal performance and they
00:16:56 --> 00:16:58 met stringent structural durability and
00:16:58 --> 00:17:01 environment midle sustainability
00:17:01 --> 00:17:04 standards now as we reported last week
00:17:04 --> 00:17:06 the consumer adversity group Choice has
00:17:06 --> 00:17:08 discovered that car manufacturers are
00:17:08 --> 00:17:10 not only spying on you when you drive
00:17:10 --> 00:17:12 recording everything you do but most of
00:17:12 --> 00:17:14 them are passing that data onto
00:17:14 --> 00:17:16 Government and law enforcement the
00:17:16 --> 00:17:18 choice investigation found that most of
00:17:18 --> 00:17:20 Australia's popular makes of car collect
00:17:20 --> 00:17:23 and share data ranging from fuel usage
00:17:23 --> 00:17:25 how you accelerate how you apply your
00:17:25 --> 00:17:27 brakes how fast you take corners and
00:17:27 --> 00:17:29 just about every other as ECT of your
00:17:29 --> 00:17:32 driving even where you're going worse
00:17:32 --> 00:17:33 still some are also recording what you
00:17:34 --> 00:17:36 see in the car who you're calling or
00:17:36 --> 00:17:37 who's calling you on the phone the
00:17:37 --> 00:17:39 content of your smartphone and even
00:17:39 --> 00:17:42 videoing what's going on in the car with
00:17:42 --> 00:17:44 the details we're joined by technology
00:17:44 --> 00:17:46 editor Alex saharov from Tech advice
00:17:47 --> 00:17:48 start life there's a lot of concern I
00:17:48 --> 00:17:51 mean we've got the uh security cameras
00:17:51 --> 00:17:52 being spied upon people are worried
00:17:52 --> 00:17:54 about how much data that cars are
00:17:54 --> 00:17:56 collecting you know EVS are collecting
00:17:56 --> 00:17:59 all this data on you but also Wi-Fi it's
00:17:59 --> 00:18:01 and just mobile phones and also your
00:18:01 --> 00:18:04 vacuum cleaner is spying on you too yeah
00:18:04 --> 00:18:06 well I mean anything that is connected
00:18:06 --> 00:18:07 to the internet especially if it has a
00:18:07 --> 00:18:10 camera or a microphone could in theory
00:18:10 --> 00:18:11 be hacked and that's the concern of the
00:18:11 --> 00:18:14 modern world I saw on X a post that said
00:18:14 --> 00:18:16 the next big pandemic might not be a
00:18:16 --> 00:18:18 medical virus but a computer virus
00:18:19 --> 00:18:20 because we're so connected to our
00:18:20 --> 00:18:22 technologies that if a computer virus
00:18:22 --> 00:18:24 comes and wipes everything out and takes
00:18:24 --> 00:18:26 it offline even for a few hours let
00:18:26 --> 00:18:28 alone days or weeks that's going to
00:18:28 --> 00:18:30 disrupt the modern world and we did see
00:18:30 --> 00:18:32 a taste of what that was like with the
00:18:32 --> 00:18:34 crowd strike outage a few weeks ago
00:18:34 --> 00:18:36 where computers running Windows were
00:18:36 --> 00:18:39 running this crowd strike software which
00:18:39 --> 00:18:41 had privileged access into the system
00:18:41 --> 00:18:43 and there was some sort of glitch that
00:18:43 --> 00:18:45 fritzed the kernel inside of Windows and
00:18:45 --> 00:18:46 then we had airlines that couldn't board
00:18:46 --> 00:18:48 people you couldn't make payments
00:18:48 --> 00:18:50 through your card systems Supermarket
00:18:50 --> 00:18:52 payment terminals you know and the the
00:18:52 --> 00:18:54 machines were shut down so modern
00:18:54 --> 00:18:56 security and the lack of it is a big
00:18:56 --> 00:18:58 problem and telra the biggest phone
00:18:58 --> 00:19:00 compy in Australia has a new
00:19:00 --> 00:19:01 announcement that because nearly $3
00:19:01 --> 00:19:04 billion Australian was lost to scammers
00:19:04 --> 00:19:07 in 2023 they're looking at how this
00:19:07 --> 00:19:09 Prospect of being targeted is driving
00:19:09 --> 00:19:11 many of us to change how we use our
00:19:11 --> 00:19:13 mobile phone 86% of Australians who own
00:19:13 --> 00:19:15 a mobile or smartphone are concerned
00:19:15 --> 00:19:16 about cyber criminals targeting their
00:19:16 --> 00:19:19 information and in the last 12 months
00:19:19 --> 00:19:22 one in five or 18% of Aussies have spent
00:19:22 --> 00:19:24 less time browsing the internet on their
00:19:24 --> 00:19:26 phones whilst almost a third of mobile
00:19:26 --> 00:19:28 users equivalent to about 6 million
00:19:28 --> 00:19:30 Australians are now using their phones
00:19:30 --> 00:19:32 almost exclusively for calls and texts
00:19:32 --> 00:19:34 and this is also a concern when you
00:19:34 --> 00:19:36 realize that many people haven't updated
00:19:36 --> 00:19:38 their phones to the newest versions of
00:19:38 --> 00:19:41 iOS or Android and many of the Android
00:19:41 --> 00:19:43 users if they have a cheaper phone that
00:19:43 --> 00:19:45 hasn't been updated in three or 4 years
00:19:45 --> 00:19:47 it's probably not getting the security
00:19:47 --> 00:19:49 update anymore so one of the things that
00:19:49 --> 00:19:51 teler is doing and I'm sure we'll see
00:19:51 --> 00:19:53 similar moves from the other big Telos
00:19:53 --> 00:19:54 because once one of them moves in this
00:19:54 --> 00:19:56 regard a lot of them do too telra is
00:19:56 --> 00:19:58 giving its customers who have the mind
00:19:58 --> 00:20:01 Telstra app which any Telstra customer
00:20:01 --> 00:20:02 can download for free they're getting
00:20:02 --> 00:20:05 these device Security Essentials which
00:20:05 --> 00:20:08 is powered by macae and so it's got a
00:20:08 --> 00:20:10 Wi-Fi scanner when you're at a cafe or
00:20:10 --> 00:20:12 an airport or on the go it's able to
00:20:12 --> 00:20:15 scan public Wi-Fi networks for security
00:20:15 --> 00:20:17 threats and alerts you to potential risk
00:20:17 --> 00:20:18 before you browse and of course you
00:20:18 --> 00:20:20 should be using a VPN when you're on
00:20:20 --> 00:20:22 public Wi-Fi but this app doesn't offer
00:20:22 --> 00:20:24 that but you can get vpns quite
00:20:24 --> 00:20:25 inexpensively there's also a safe
00:20:25 --> 00:20:28 browsing feature so this is where you
00:20:28 --> 00:20:30 will get alerts before accessing risky
00:20:30 --> 00:20:32 websites and links because it's it's
00:20:32 --> 00:20:33 scanning those and I mean there's a
00:20:33 --> 00:20:35 security issue as well do you want some
00:20:35 --> 00:20:36 software scanning you but then if you
00:20:36 --> 00:20:37 don't have it and you click on a link
00:20:37 --> 00:20:39 that potentially dodgy could somebody
00:20:40 --> 00:20:41 hack into your phone obviously it's a
00:20:41 --> 00:20:43 possibility and also there's a device
00:20:43 --> 00:20:44 check which is a security scan that
00:20:44 --> 00:20:46 helps detect and protect your device
00:20:46 --> 00:20:49 against suspicious apps and potentially
00:20:49 --> 00:20:50 harmful software now there are
00:20:50 --> 00:20:52 differences for Android and iPhone users
00:20:52 --> 00:20:54 for Android users the feature will scan
00:20:54 --> 00:20:56 your phone and other devices for viruses
00:20:56 --> 00:20:59 and malware on iPhones Apple controls
00:20:59 --> 00:21:01 the security and they do already have
00:21:01 --> 00:21:03 some built-in security to catch a lot of
00:21:03 --> 00:21:05 the malware but Tel's device feature
00:21:05 --> 00:21:07 will still scan your device software and
00:21:07 --> 00:21:09 passcode setting to ensure it's up to
00:21:09 --> 00:21:10 date so look it's something that the
00:21:11 --> 00:21:12 phone companies are doing to try and
00:21:12 --> 00:21:15 more proactively protect their customers
00:21:15 --> 00:21:16 and it's a bit like with the banks in
00:21:16 --> 00:21:19 the UK if you lose money to scammer the
00:21:19 --> 00:21:21 UK Banks now have to reimburse you in
00:21:21 --> 00:21:23 Australia they don't and I have seen a
00:21:23 --> 00:21:25 lot of song and dance from the banks in
00:21:25 --> 00:21:26 Australia saying that they're triple
00:21:26 --> 00:21:28 cheing when you send money and doing
00:21:28 --> 00:21:30 these whatever they can so they don't
00:21:30 --> 00:21:31 have to be forced by the government to
00:21:31 --> 00:21:33 reimburse people who've been scammed so
00:21:33 --> 00:21:35 if you've got a teler account and you've
00:21:35 --> 00:21:37 got the my teler app on your Android or
00:21:37 --> 00:21:39 iOS phone you go into the app and you
00:21:39 --> 00:21:41 can turn on the new security feature
