SpaceTime Series 27 Episode 121
*A New Planet Discovered Orbiting Barnard's Star
Astronomers have discovered a new exoplanet orbiting Barnard's Star, the closest single star to the Sun. This newly found planet, Barnard b, has about half the mass of Earth and completes an orbit around its host star every three Earth days. Located 5.96 light-years away, Barnard's Star is a small red dwarf in the constellation Ophiuchus. The discovery was made using the European Southern Observatory's Very Large Telescope and has sparked interest due to its low mass and proximity to its star. The study also hints at the existence of three more potential exoplanets in the system, although additional observations are needed for confirmation.
*ESA's Hera Mission Launch
The European Space Agency's Hera mission is set to launch, aimed at exploring the aftermath of NASA's DART mission impact on the asteroid Dimorphos. The mission will provide detailed analysis of the impact site and the asteroid's composition, mass, and structural changes. Hera will also deploy two cubesats, Milani and Juventus, to perform close-up observations and experiments. The mission is crucial for understanding how to protect Earth from potential asteroid threats in the future.
*Spectacular Annular Solar Eclipse
A stunning annular solar eclipse, known as a "ring of fire," has been witnessed by people across the eastern and southern Pacific, as well as parts of South America. The eclipse, which occurs when the Moon is slightly further from Earth, left a bright ring of sunlight visible around the Moon's silhouette. The event was best viewed from Easter Island and parts of Argentina and Chile, with partial views seen in other regions including Bolivia, Peru, and New Zealand.

00:00:06 --> 00:00:10 2024 coming up on SpaceTime scientists
00:00:10 --> 00:00:11 discover a planet orbiting the nearest
00:00:12 --> 00:00:14 single start of the Sun the European
00:00:14 --> 00:00:17 space agency's planetary defense Hera
00:00:17 --> 00:00:20 Mission slated for launch today and a
00:00:20 --> 00:00:23 spectacular Ring of Fire around the Sun
00:00:24 --> 00:00:27 all that and more coming up on
00:00:27 --> 00:00:30 SpaceTime welcome to SpaceTime with
00:00:30 --> 00:00:32 Stuart
00:00:32 --> 00:00:38 [Music]
00:00:46 --> 00:00:48 Gary astronomers have discovered a
00:00:48 --> 00:00:51 planet orbiting barard star the closest
00:00:51 --> 00:00:53 single star of the Sun a newly
00:00:53 --> 00:00:55 discovered exoplanet has about half the
00:00:55 --> 00:00:57 mass of the Earth and orbits its host
00:00:57 --> 00:01:00 star in just over three Earth days
00:01:00 --> 00:01:02 barard star is a small spectral type
00:01:02 --> 00:01:05 Emir dwarf star in the constellation of
00:01:05 --> 00:01:09 fuus it's located some 5.96 L years from
00:01:09 --> 00:01:11 the Sun that makes it the nearest start
00:01:11 --> 00:01:14 of the sun after the alpha centor triple
00:01:14 --> 00:01:17 star system they're located around 4.3
00:01:17 --> 00:01:20 light years away bardar has a mass about
00:01:20 --> 00:01:24 16% that of the sun and it has about 19%
00:01:24 --> 00:01:26 of the Sun's diameter the new planetary
00:01:27 --> 00:01:28 Discovery reported in the journal
00:01:28 --> 00:01:30 astronomy and astrophysics was made
00:01:30 --> 00:01:32 using the European Southern
00:01:32 --> 00:01:35 observatory's very large telescope the
00:01:35 --> 00:01:38 VT and the observations don't end there
00:01:38 --> 00:01:40 there are also some tantalizing hints of
00:01:40 --> 00:01:41 the possible existence of three more
00:01:41 --> 00:01:43 exoplanetary candidates in various
00:01:43 --> 00:01:46 orbits around the star and that could
00:01:46 --> 00:01:48 make this star system a reflection of
00:01:48 --> 00:01:51 our own solar system despite a promising
00:01:51 --> 00:01:53 detection back in 2018 no Planet
00:01:53 --> 00:01:55 orbiting Barnard Star had been confirmed
00:01:55 --> 00:01:58 until now the study's lead author JN
00:01:58 --> 00:02:01 Gonzalez Hernandez from the astrophysics
00:02:01 --> 00:02:03 Institute of the Canary Islands says the
00:02:03 --> 00:02:05 new discovery was the result of more
00:02:05 --> 00:02:07 than 5 years of
00:02:07 --> 00:02:09 observations see the team were looking
00:02:09 --> 00:02:11 for signals of possible exoplanets
00:02:11 --> 00:02:14 within the star's habitable zone that's
00:02:14 --> 00:02:15 the distance from the Star where
00:02:15 --> 00:02:17 temperatures would allow liquid water
00:02:17 --> 00:02:19 essential for Life as we know it to
00:02:19 --> 00:02:21 exist on the planet's surface red
00:02:21 --> 00:02:24 dwarves like Barnard star are often
00:02:24 --> 00:02:25 targeted by astronomers because their
00:02:25 --> 00:02:27 habitable zones are much closer into the
00:02:27 --> 00:02:30 star than hotter stars like our son
00:02:30 --> 00:02:32 that means the planets orbiting within
00:02:32 --> 00:02:34 this Zone have shorter orbital periods
00:02:34 --> 00:02:36 allowing astronomers to monitor them
00:02:36 --> 00:02:38 over several days or weeks rather than
00:02:38 --> 00:02:41 Years also because red dwarf stars are
00:02:41 --> 00:02:43 far less massive than the sun they're
00:02:43 --> 00:02:45 more easily disturbed by the
00:02:45 --> 00:02:47 gravitational pull of an orbiting planet
00:02:47 --> 00:02:50 around them therefore their spectral
00:02:50 --> 00:02:51 movements towards and away from The
00:02:51 --> 00:02:54 Observer are more easily identified in
00:02:54 --> 00:02:56 other words they're easier to spot by
00:02:56 --> 00:02:59 the wobble method the new planet which
00:02:59 --> 00:03:01 has been named Barnard B is about 20
00:03:01 --> 00:03:03 times closer to Barnard star than
00:03:03 --> 00:03:05 Mercury is to the Sun that gives it a
00:03:05 --> 00:03:09 surface temperature of around 125° C and
00:03:09 --> 00:03:12 that puts it inside the habitable zone a
00:03:12 --> 00:03:14 region where it's too hot for water to
00:03:14 --> 00:03:17 exist in a liquid state what makes this
00:03:17 --> 00:03:19 discovery really interesting is that
00:03:19 --> 00:03:21 barard b is one of the lowest Mass
00:03:21 --> 00:03:23 exoplanets found so far and one of only
00:03:23 --> 00:03:26 a few with less mass than the earth for
00:03:26 --> 00:03:28 their observations the authors used
00:03:28 --> 00:03:30 espresso that a highly precise
00:03:30 --> 00:03:32 spectrometer specifically designed to
00:03:32 --> 00:03:34 measure the wobble of a star caused by
00:03:34 --> 00:03:36 the gravitational pull of orbiting
00:03:36 --> 00:03:39 planets interestingly however this new
00:03:39 --> 00:03:41 data doesn't support the existence of
00:03:41 --> 00:03:43 the exoplanet first speculated to exist
00:03:43 --> 00:03:46 back in 2018 the observations simply no
00:03:46 --> 00:03:48 longer support that as I mentioned
00:03:48 --> 00:03:50 earlier in addition to the confirmed
00:03:50 --> 00:03:52 Planet the authors also found hints of
00:03:52 --> 00:03:54 three more exoplanetary candidates
00:03:54 --> 00:03:57 orbiting the same star these candidates
00:03:57 --> 00:03:58 however will require additional
00:03:58 --> 00:04:00 observations to be
00:04:00 --> 00:04:02 confirmed it's also worth noting that
00:04:02 --> 00:04:05 barard star is slowly getting closer to
00:04:05 --> 00:04:08 our own solar system measurements of its
00:04:08 --> 00:04:10 proper motion through space show that it
00:04:10 --> 00:04:13 has a relative lateral speed of around
00:04:13 --> 00:04:14
00:04:14 --> 00:04:17 km/s and the Stars radio velocity is 110
00:04:17 --> 00:04:20 km/s as measured from its blue shift due
00:04:20 --> 00:04:22 to its motion towards the sun now
00:04:22 --> 00:04:24 combined with its proper motion and
00:04:24 --> 00:04:27 distance this gives it a space velocity
00:04:27 --> 00:04:29 that is an actual speed relative to the
00:04:29 --> 00:04:32 motion of our Sun of 142. 6
00:04:32 --> 00:04:35 km/s now when you work all that out it
00:04:35 --> 00:04:37 means barard star will make its closest
00:04:37 --> 00:04:39 approach to the sun in around 9
00:04:39 --> 00:04:41 years from now at which point it'll be
00:04:41 --> 00:04:45 within 3.75 light years of the earth
00:04:45 --> 00:04:47 that's closer than the alpha centor star
00:04:47 --> 00:04:52 system is now this is spacetime still to
00:04:52 --> 00:04:54 come the European space agency's Hera
00:04:54 --> 00:04:56 planetary defense Mission slated for
00:04:56 --> 00:04:59 launch today and a spectacular Ring of
00:04:59 --> 00:05:02 Fire seen around the Sun all that and
00:05:02 --> 00:05:08 more coming up on
00:05:08 --> 00:05:19 [Music]
00:05:19 --> 00:05:21 SpaceTime the European space agency's
00:05:21 --> 00:05:24 Hera planetary defense mission is slated
00:05:24 --> 00:05:26 for launch today the
00:05:26 --> 00:05:29 1 kg spacecraft Will Fly Above b a
00:05:30 --> 00:05:32 SpaceX Falcon 9 rocket from the Cape
00:05:32 --> 00:05:34 Canal space force base in Florida on a
00:05:34 --> 00:05:36 2year journey to the near Earth asteroid
00:05:36 --> 00:05:40 Diddy moss and its Tiny Moon dimorphus
00:05:40 --> 00:05:42 dimorphus was the target of NASA's Dart
00:05:42 --> 00:05:44 double asteroid redirection test which
00:05:44 --> 00:05:46 was designed to slam and impact a
00:05:46 --> 00:05:48 spacecraft into an asteroid to see if
00:05:48 --> 00:05:50 they could deflect it onto a different
00:05:50 --> 00:05:53 trajectory the dart spacecraft hit di
00:05:53 --> 00:05:55 morphus on September the 26th 2022
00:05:55 --> 00:05:57 impacting the asteroid at a relative
00:05:57 --> 00:06:01 speed of 6.1 km per second and the Crash
00:06:01 --> 00:06:05 was spectacular it altered Doris's orbit
00:06:05 --> 00:06:07 around dyos shortening its orbital
00:06:07 --> 00:06:09 period by around 32 minutes and leaving
00:06:09 --> 00:06:12 a massive crater and debris cloud in its
00:06:12 --> 00:06:14 wake the test marked the first time
00:06:15 --> 00:06:16 humanity had demonstrated its ability to
00:06:17 --> 00:06:19 deflect an asteroid providing proof of
00:06:19 --> 00:06:21 concept that we might in the future be
00:06:21 --> 00:06:23 able to protect the Earth from a
00:06:23 --> 00:06:25 potential asteroid impact simply by
00:06:25 --> 00:06:28 altering the asteroids path given enough
00:06:28 --> 00:06:30 time of course Pera which is named after
00:06:30 --> 00:06:32 the Great Goddess of Marriage will
00:06:32 --> 00:06:34 undertake a forensic follow-up
00:06:34 --> 00:06:36 evaluation Mission finding out exactly
00:06:36 --> 00:06:39 what happened in the wake of the impact
00:06:39 --> 00:06:42 its payload includes a series of cameras
00:06:42 --> 00:06:44 altimeters and spectrometers it'll help
00:06:44 --> 00:06:46 scientists answer some key outstanding
00:06:46 --> 00:06:49 questions such as the exact mass and
00:06:49 --> 00:06:51 composition of dime orice the structural
00:06:51 --> 00:06:53 effects of the impact the size of the
00:06:53 --> 00:06:55 crater formed by the Collision an
00:06:55 --> 00:06:57 analysis of the expanding debris Cloud
00:06:57 --> 00:07:00 caused by the impact and with it morphus
00:07:00 --> 00:07:02 may have actually been fractured by the
00:07:02 --> 00:07:04 impact and is now really nothing more
00:07:04 --> 00:07:06 than a bunch of rocks held together by
00:07:06 --> 00:07:09 weak gravity it'll also carry out
00:07:09 --> 00:07:11 technology demonstration experiments
00:07:11 --> 00:07:13 including the deployment of isa's first
00:07:13 --> 00:07:16 deep space Cube sets Milani and Juventus
00:07:16 --> 00:07:18 two small spacecraft that will approach
00:07:18 --> 00:07:21 the asteroid and eventually land on it
00:07:21 --> 00:07:23 as well as Gathering crucial close-up
00:07:23 --> 00:07:25 dater on the surface characteristics of
00:07:25 --> 00:07:26 the asteroid Hera will explore the
00:07:27 --> 00:07:28 binary system as a whole in
00:07:28 --> 00:07:30 unprecedented Det detail becoming the
00:07:30 --> 00:07:32 first mission to study a binary asteroid
00:07:33 --> 00:07:35 system in depth it'll study both
00:07:35 --> 00:07:37 asteroids internal procity and structure
00:07:37 --> 00:07:39 using a low frequency radar aboard the
00:07:39 --> 00:07:42 cubat Juventus meanwhile Milani will
00:07:42 --> 00:07:44 help collect spectral data from the
00:07:44 --> 00:07:46 surface of both asteroids it'll also
00:07:46 --> 00:07:48 help identify the presence of debris
00:07:48 --> 00:07:51 dust in the surrounding space dimorphus
00:07:51 --> 00:07:53 will be mapped completely with a special
00:07:53 --> 00:07:55 resolution of a few meters and the
00:07:55 --> 00:07:57 vicinity of the impact will be mapped
00:07:57 --> 00:08:00 with a resolution down to just 10 cm M
00:08:00 --> 00:08:02 the mass of the Moon di Orphus will be
00:08:02 --> 00:08:05 estimated with high accuracy that will
00:08:05 --> 00:08:06 allow a direct estimate of the momentum
00:08:06 --> 00:08:09 transfer efficiency of the D impact
00:08:09 --> 00:08:11 that's an important step as binary
00:08:11 --> 00:08:14 asteroid systems make up some 15% of all
00:08:14 --> 00:08:16 known asteroids the mission will also
00:08:16 --> 00:08:18 test Advanced autonomous navigation
00:08:18 --> 00:08:21 Technology based on visual Data before
00:08:21 --> 00:08:24 rund deing with Diddy and demorphis in
00:08:24 --> 00:08:26 December 2026 Hera will undertake a
00:08:26 --> 00:08:28 gravity assist flyby of Mars in March
00:08:28 --> 00:08:30 next year
00:08:30 --> 00:08:31 and that will give scientists the chance
00:08:31 --> 00:08:34 to study the marim moon deos in some
00:08:34 --> 00:08:37 detail this report on the Hera Mission
00:08:37 --> 00:08:39 from Isa
00:08:39 --> 00:08:42 TV there's a mystery out there in deep
00:08:42 --> 00:08:45 space and solving it will make earth
00:08:45 --> 00:08:47 safer that's why the European space
00:08:47 --> 00:08:50 agency's hero mission is taking shape to
00:08:50 --> 00:08:53 go where one particular spacecraft has
00:08:53 --> 00:08:56 gone before on the 26th of September
00:08:56 --> 00:09:01 2022 at 6.1 km m/ second NASA's D
00:09:02 --> 00:09:05 spacecraft crashed into the demorphis
00:09:05 --> 00:09:09 asteroid part of our solar system
00:09:09 --> 00:09:12 changed the impact Shrunk the orbit of
00:09:13 --> 00:09:15 the Great Pyramid siiz demorphis around
00:09:15 --> 00:09:18 its parent asteroid the mountain-sized
00:09:19 --> 00:09:22 didmus it also sent a plume of debris
00:09:22 --> 00:09:24 thousands of kilometers across
00:09:24 --> 00:09:27 space this Grand experiment was
00:09:27 --> 00:09:30 performed to prove we could defend Earth
00:09:30 --> 00:09:33 against an incoming asteroid by striking
00:09:33 --> 00:09:37 it with a spacecraft to deflect it D
00:09:37 --> 00:09:39 succeeded but that still leaves many
00:09:39 --> 00:09:41 things scientists don't
00:09:41 --> 00:09:45 know what is the precise mass and makeup
00:09:45 --> 00:09:48 of demorphis what did the impact do to
00:09:48 --> 00:09:52 the asteroid how big is the crater left
00:09:52 --> 00:09:55 by dart's Collision or has demorphis
00:09:55 --> 00:09:57 completely cracked apart held together
00:09:57 --> 00:10:01 by its own weak Gra
00:10:01 --> 00:10:04 that's why we're going back with issa's
00:10:04 --> 00:10:06 hero
00:10:07 --> 00:10:10 mission after a 2year trek through space
00:10:10 --> 00:10:14 and a Mars flyby Hera will go into orbit
00:10:14 --> 00:10:17 around de morphos and begin its crash
00:10:17 --> 00:10:18 site
00:10:18 --> 00:10:21 investigation this will be a hazardous
00:10:21 --> 00:10:23 undertaking the impact might have left
00:10:24 --> 00:10:25 clouds of debris hanging in the
00:10:25 --> 00:10:27 asteroids
00:10:27 --> 00:10:30 vicinity but Hera is not not going alone
00:10:31 --> 00:10:33 it takes with it two briefcase sized
00:10:33 --> 00:10:37 Cube sets to go in closer and take more
00:10:37 --> 00:10:39 risks that their parents
00:10:39 --> 00:10:42 spacecraft one will identify the
00:10:42 --> 00:10:44 minerals making up demorphis while the
00:10:45 --> 00:10:48 other will unfur a radar antenna to make
00:10:48 --> 00:10:51 the first subsurface probe of an
00:10:51 --> 00:10:54 asteroid and they'll end their duties by
00:10:54 --> 00:10:56 touching down on demorphis to gather
00:10:57 --> 00:10:59 extra data on its surface and gravity
00:11:00 --> 00:11:03 field by the end of Hero's observations
00:11:03 --> 00:11:05 demorphis will become the best studied
00:11:05 --> 00:11:10 asteroid in history which is vital
00:11:10 --> 00:11:12 because if a body of this size ever
00:11:12 --> 00:11:16 struck Earth it could destroy a whole
00:11:16 --> 00:11:19 city the dinosaurs had no defense
00:11:19 --> 00:11:22 against asteroids because they never had
00:11:22 --> 00:11:24 a space
00:11:24 --> 00:11:27 agency but through Hera we are teaching
00:11:27 --> 00:11:30 ourselves what we can do to reduce this
00:11:30 --> 00:11:38 Hazard and make space
00:11:38 --> 00:11:42 safer this is spacetime still to come a
00:11:42 --> 00:11:44 spectacular Ring of Fire around the Sun
00:11:44 --> 00:11:46 and later in the science report a new
00:11:46 --> 00:11:49 study finally explains why the tong of
00:11:49 --> 00:11:52 volcano blast was as powerful as it was
00:11:52 --> 00:11:55 all that and more still to come on
00:11:55 --> 00:12:00 SpaceTime
00:12:00 --> 00:12:11 [Music]
00:12:11 --> 00:12:13 the people of the EAS andn South Pacific
00:12:13 --> 00:12:15 and South America have been treed to a
00:12:15 --> 00:12:19 spectacular annul solar eclipse an annul
00:12:19 --> 00:12:21 solar eclipse occurs when the moon's
00:12:21 --> 00:12:23 elliptical orbit is slightly further
00:12:23 --> 00:12:25 away from the earth making it appear
00:12:25 --> 00:12:28 smaller and so when it lines up between
00:12:28 --> 00:12:30 the Sun the Earth to create a solar
00:12:30 --> 00:12:32 eclipse it doesn't quite block out all
00:12:32 --> 00:12:35 of the sun's disc but instead leaves a
00:12:35 --> 00:12:38 spectacular ring of fire in the darken
00:12:38 --> 00:12:41 Sky the event began over the easn South
00:12:41 --> 00:12:44 Pacific Ocean before making landfall
00:12:44 --> 00:12:46 across the southern tip of South America
00:12:46 --> 00:12:48 people on Easter iseland and parts of
00:12:48 --> 00:12:50 Argentina and Chile were in the best
00:12:50 --> 00:12:52 positions to witness the spectacular
00:12:52 --> 00:12:55 Celestial show The Narrow Path of
00:12:55 --> 00:12:57 annularity then continued into the South
00:12:57 --> 00:13:00 Atlantic Ocean before finally ending a
00:13:00 --> 00:13:02 partial eclipse was observed from
00:13:02 --> 00:13:05 Bolivia Peru Paraguay Uruguay as well as
00:13:05 --> 00:13:08 parts of Brazil Mexico New Zealand and
00:13:08 --> 00:13:09 several islands in the Pacific and
00:13:09 --> 00:13:12 Atlantic Oceans it was the second solar
00:13:12 --> 00:13:15 eclipse this year April's total solar
00:13:15 --> 00:13:17 eclipse dazzled Sky Watchers in parts of
00:13:17 --> 00:13:19 Mexico the United States and Eastern
00:13:19 --> 00:13:22 Canada the next total solar eclipse
00:13:22 --> 00:13:25 won't arrive until 2026 and it'll pass
00:13:25 --> 00:13:27 over the northern fringes of Greenland
00:13:27 --> 00:13:30 Iceland and Spain but before that two
00:13:30 --> 00:13:32 more partial solar eclipses will take
00:13:32 --> 00:13:34 place next year one in March the other
00:13:34 --> 00:13:37 in September the March event on the 29th
00:13:37 --> 00:13:39 will be visible mainly from eastern
00:13:39 --> 00:13:41 North America Europe Siberia and
00:13:41 --> 00:13:44 Northwestern Africa the year's second
00:13:44 --> 00:13:46 partial solar eclipse will take place on
00:13:46 --> 00:13:48 September the 21st and it'll be visible
00:13:48 --> 00:13:50 over Antarctica New Zealand and the
00:13:50 --> 00:13:53 islands of the South Pacific people in
00:13:53 --> 00:13:55 Tasmania and along the east coast of
00:13:55 --> 00:13:57 Australia will also be able to see just
00:13:57 --> 00:13:59 an Ever So slight sliver of the the sun
00:13:59 --> 00:14:02 covered by the Moon it won't be till
00:14:02 --> 00:14:04 2028 that Australians will get to see
00:14:04 --> 00:14:08 their next total solar eclipse this is
00:14:08 --> 00:14:23 [Music]
00:14:23 --> 00:14:25 spacetime and time now to take a brief
00:14:26 --> 00:14:27 look at some of the other stories making
00:14:27 --> 00:14:29 news in science this week with a science
00:14:29 --> 00:14:32 report a new study has concluded that
00:14:32 --> 00:14:34 the hunga Tonga underwater volcano one
00:14:34 --> 00:14:36 of the largest volcanic eruptions in
00:14:36 --> 00:14:38 recorded history was triggered by an
00:14:38 --> 00:14:40 explosion most likely due to gas
00:14:40 --> 00:14:42 compressed Rock which released as much
00:14:42 --> 00:14:46 energy as five thermonuclear explosions
00:14:46 --> 00:14:47 the findings reported in the journal
00:14:47 --> 00:14:49 geophysical research letters and based
00:14:49 --> 00:14:51 on computer models suggesting gas
00:14:52 --> 00:14:53 compressed Rock being trapped underneath
00:14:53 --> 00:14:56 a shallow sea acted as a sort of
00:14:56 --> 00:14:58 overcook pressure cooker the study's
00:14:58 --> 00:15:00 author from the Australian National
00:15:00 --> 00:15:02 University analyzed the cataclysmic
00:15:02 --> 00:15:04 events noisy but valuable seismic
00:15:04 --> 00:15:06 records in order to decipher its
00:15:06 --> 00:15:09 mysterious physical mechanism they found
00:15:09 --> 00:15:11 the explosion caused a massive vertical
00:15:11 --> 00:15:13 push of water upwards into the
00:15:13 --> 00:15:15 atmosphere causing tsunamis that reached
00:15:15 --> 00:15:19 as high as 45 M on nearby
00:15:19 --> 00:15:21 Islands scientists have developed a
00:15:21 --> 00:15:23 version of a zic and wovie which could
00:15:23 --> 00:15:26 involve a once a month rather than
00:15:26 --> 00:15:28 weekly injection the study's authors
00:15:28 --> 00:15:30 present their findings at the annual
00:15:30 --> 00:15:32 meeting of the European Association for
00:15:32 --> 00:15:34 the study of diabetes say they've
00:15:34 --> 00:15:36 developed a new drug delivery system
00:15:36 --> 00:15:38 that could cut the dosing schedule for
00:15:38 --> 00:15:40 the type 2 diabetes way control drug
00:15:40 --> 00:15:43 stide to just once a month the new drug
00:15:43 --> 00:15:45 delivery system involves a hydrogel
00:15:45 --> 00:15:48 composed of two biodegradable Plastics
00:15:48 --> 00:15:50 these are injected Under the Skin and
00:15:50 --> 00:15:52 then release the drug slowly over 1 to 3
00:15:52 --> 00:15:55 months lab tests showed extended and
00:15:55 --> 00:15:57 consistent release rates over 3 months
00:15:57 --> 00:15:59 suggesting the hydro Gill was well
00:15:59 --> 00:16:02 tolerated and didn't cause any
00:16:02 --> 00:16:05 inflammation a new study claims those
00:16:05 --> 00:16:07 cutesy puppy voices people often use
00:16:07 --> 00:16:09 when speaking with their pets might not
00:16:09 --> 00:16:11 just be because they're overwhelmed with
00:16:11 --> 00:16:13 love but could actually have evolved
00:16:13 --> 00:16:16 over time to help Man's Best Friend
00:16:16 --> 00:16:18 understand you better a report in the
00:16:18 --> 00:16:20 journal plus biology analyzed the vocal
00:16:20 --> 00:16:23 sounds of 30 dogs as well as 27 humans
00:16:23 --> 00:16:25 across five language groups speaking to
00:16:25 --> 00:16:28 other people and 22 humans across those
00:16:28 --> 00:16:30 same language language groups speaking
00:16:30 --> 00:16:32 to dogs they also looked at the brain
00:16:32 --> 00:16:35 responses to speech in both humans and
00:16:35 --> 00:16:37 dogs they found that humans are much
00:16:37 --> 00:16:39 faster talkers than dogs with a speech R
00:16:39 --> 00:16:42 of about four syllables per second while
00:16:42 --> 00:16:44 dogs tend to bark and growl and woof and
00:16:44 --> 00:16:46 whine at about two vocalizations per
00:16:46 --> 00:16:49 second the brain scans also found that
00:16:49 --> 00:16:51 dogs were more responsive to specific
00:16:51 --> 00:16:53 slower rhythms than humans usually speak
00:16:54 --> 00:16:56 the results imply that people could be
00:16:56 --> 00:16:58 changing their speech and Tempo in order
00:16:58 --> 00:17:01 to match what puppies can
00:17:01 --> 00:17:03 process in a finding that's bound to
00:17:03 --> 00:17:05 make every man shake in their boots with
00:17:05 --> 00:17:08 fear a new study is shown that women are
00:17:08 --> 00:17:11 now more and more turning to psychics to
00:17:11 --> 00:17:12 find out if their husbands are cheating
00:17:12 --> 00:17:15 on them but as Tim menum from australi
00:17:15 --> 00:17:17 Skeptics explains the study was limited
00:17:17 --> 00:17:19 confined to those interested in a
00:17:19 --> 00:17:22 specific type of extramarital activity
00:17:22 --> 00:17:23 this is a dangerous one mainly because
00:17:23 --> 00:17:25 the source of the story actually it
00:17:25 --> 00:17:29 comes from a survey done by a rantic
00:17:29 --> 00:17:31 website dating service thing called
00:17:31 --> 00:17:34 illicit encounters which is actually for
00:17:34 --> 00:17:36 married couples and presumably for
00:17:36 --> 00:17:38 married couples or for members thereof
00:17:38 --> 00:17:40 to go out and find alternative Partners
00:17:40 --> 00:17:43 so to lead leading to you know um you
00:17:43 --> 00:17:45 had a name for that back in the 70s and
00:17:45 --> 00:17:47 80s didn't they where you put your car
00:17:47 --> 00:17:49 keys in a dish or something little wife
00:17:49 --> 00:17:50 swapping wife swapping it was called
00:17:50 --> 00:17:52 yeah very sexist that term but yeah I
00:17:52 --> 00:17:53 don't yeah I don't think anyone did
00:17:53 --> 00:17:55 husband swapping you know well yummy
00:17:55 --> 00:17:57 mummies are always better looking than
00:17:57 --> 00:18:00 their husband this this website this
00:18:00 --> 00:18:02 dating service called ilicit encounters
00:18:02 --> 00:18:04 did a survey of its members who are
00:18:04 --> 00:18:05 people's customers if you like who are
00:18:05 --> 00:18:07 all there looking for Affairs Etc and
00:18:07 --> 00:18:09 they found out that a lot of them it's
00:18:09 --> 00:18:11 known to psychics to find out if their
00:18:11 --> 00:18:14 partner is wandering is having an affair
00:18:14 --> 00:18:16 and according to this survey 52% of
00:18:16 --> 00:18:18 those who took part of the survey um
00:18:18 --> 00:18:21 hoped to uncover infidelities from their
00:18:21 --> 00:18:23 partners and 68% of people had
00:18:23 --> 00:18:26 suspicions so people out there based on
00:18:26 --> 00:18:28 this website are looking for wandering
00:18:28 --> 00:18:29 people that is sort of unsure so they're
00:18:30 --> 00:18:31 turning to psychics once upon a time it
00:18:31 --> 00:18:33 might have been a private investigator
00:18:33 --> 00:18:35 to go around and sort of photograph your
00:18:35 --> 00:18:37 husband or wife meeting up with other
00:18:37 --> 00:18:38 people now they're turning to psychics
00:18:38 --> 00:18:40 for the answer whether they're getting
00:18:40 --> 00:18:41 the answer that is correct they might
00:18:41 --> 00:18:43 get the answer they want but they're not
00:18:43 --> 00:18:45 necessarily getting a correct answer is
00:18:45 --> 00:18:47 a bit uncertain but apparently it's very
00:18:47 --> 00:18:49 popular in Scotland this is It's the UK
00:18:49 --> 00:18:51 site so the largest number of people of
00:18:51 --> 00:18:54 this survey using it was 43% of women
00:18:54 --> 00:18:55 admitting to seeking Supernatural
00:18:55 --> 00:18:57 guidance in Scotland down to 31% in
00:18:57 --> 00:19:00 England 16 any Wales and only 10% of
00:19:00 --> 00:19:02 people in Northern Ireland looking for
00:19:02 --> 00:19:04 you know going to a psychic to see if
00:19:04 --> 00:19:06 their partner was wondering it tends to
00:19:06 --> 00:19:07 be apparently women going to the
00:19:08 --> 00:19:09 psychics well we've covered that before
00:19:09 --> 00:19:11 haven't we women go to psychics and see
00:19:11 --> 00:19:13 ghosts and spirits men see Bigfoot and
00:19:14 --> 00:19:16 UFOs that's right yes it's almost like a
00:19:16 --> 00:19:18 gender sort of division of these things
00:19:18 --> 00:19:19 onlyway sort of one person one
00:19:19 --> 00:19:21 particular case it was quite amusing
00:19:21 --> 00:19:22 said I was worried about this did
00:19:22 --> 00:19:24 everything to find out checking a phone
00:19:24 --> 00:19:26 analyzing Behavior installing a tracking
00:19:26 --> 00:19:28 app in in a partner's phone eventually
00:19:28 --> 00:19:29 went to the psychic to find out the
00:19:29 --> 00:19:31 psychic said yes he's having off with
00:19:31 --> 00:19:33 someone else and so she got her Revenge
00:19:33 --> 00:19:35 by having her own
00:19:35 --> 00:19:38 Affair that's right yeah so anyway it's
00:19:38 --> 00:19:40 a survey based on a very Niche group who
00:19:40 --> 00:19:42 I think are already predisposed to
00:19:42 --> 00:19:44 having elicit Affairs anyway as the as
00:19:44 --> 00:19:46 the name of the site is that's Tim mum
