my name's dylan this is the daily dance
where we dance through all the latest
science and uh world news so you should
come subscribe if you want this uh
newsletter every day where there's way
more of it i just break down the best
bits in these videos
come subscribe for free in the
description and you'll get this
beautiful email every single day all
right let's go so to begin with jwst is
kinda breaking astrophysics
it's only been operational for like a
few weeks and it's already found
evidence which kind of suggests you know
maybe there's tens hundreds maybe even a
thousand times more galaxies in the
early universe than our theoretical
models predicted so these galaxy models
might actually need a bit of revising
now because this is pretty outside the
box of what they were predicting current
models don't produce so many galaxies
like so shortly after the big bang and
no one was really expecting anything
like this and this comes from just
looking at a small tiny patch of the sky
but look we're not too sure if this is
an anomaly like maybe we got really
lucky from you know staring into a huge
clump of galaxies you know much denser
than that rest of the early universe but
we'll find out later this year when we
collect more data so this is really
awesome news but we found out that life
could travel through space but only
under very certain conditions whilst
earlier studies of uh rates of survival
for these space-faring tardigrades
there's some new research showing that
these water bears might actually be able
to survive if they're moving slow enough
initially
these researchers basically found that
they won't survive most shock pressures
that they're likely to you know
encounter during planetary landings but
some launched from their planets to
their moons lived in their simulations
because their speeds were low enough
only to exert like a small pressure so
there's still hope this is really cool
ai plus ecg heart monitors can
accurately predict diabetes and
pre-diabetes so the combination of an
algorithm measuring individual
heartbeats and an electrocardiogram the
ecg tracking can accurately predict uh
diabetes patients in this study so if
validated by larger studies this
approach actually could be treated to
screening for you know the disease in
low resource settings uh so that's
really cool uh measuring you know blood
glucose is pretty invasive and it's kind
of difficult in low resource regions of
the world so you know early detections
of this disease is probably pretty vital
you know in helping these people so i
think this is some really cool news in
more health news a new drug candidate uh
can fight off more than 300 drug
resistant bacteria whilst remaining
inactive against uh certain pathogens
and harmless uh bacteria that lives on
or in the human body
and this new molecule is actually able
to reduce the amount of drug resistant
bacteria uh in mice who have um or
urinary tract infections to
pre-infection levels all below that's
crazy and uh it performed as well or
better than existing antibiotics at
similar doses so this is really a really
good development did you guys ever watch
that eldorado kids movie and they have
this scene in it with some minds and
they're kicking these balls around and
playing this game well apparently these
balls are actually made out of like
important mayan rulers they after they
would die they would uh turn their turn
them to ash and then put them in these
balls i thought that was pretty
interesting so here's a fun little
puzzle for you i'll tell you the answer
at the end of the video you should be
able to get this one if you've been
watching my videos but what can fill a
room but takes up no space leave a
comment down under before you just skip
to the end of the video see if you can
get it so in some rocket news spacex
fired up the first and second stage of
its uh starship mega rocket on wednesday
uh in preparation for its orbital test
flight
so the static fire test basically saw
like this prototype of the heavy booster
ignite its raptor 2 engine uh at
starbase facility in bulkachika texas in
the early hours of august 10th so a
little bit a while ago but i thought i'd
report on this so over to some
environment news over the past 60 years
global forest area has declined by 81.7
million hectares a loss which is
basically contributed to the more than
60 percent in global forest area per
capita
according to this new study this loss
will you know threaten the future of
biodiversity and you know a lot of
humans something like 1.6 billion humans
worldwide so that was the end of this
newsletter and i left around with the
latest sighting of the loch desk monster
which if i scroll down here
turned out to be
yep that's an alpaca
and the answer actually we'll do the
answer at the end of the video because
we're going to do the next one as well
so over to mars subsurface water on mars
is basically defied expectations so a
new analysis of seismic data from nasa's
mars inside mission has basically showed
a couple surprises but
the major surprise is that the top 300
meters of the subsurface
benoit beneath the landing site of the
martian equator basically contain little
or no ice that's pretty depressing so
some brain scans have revealed the
hidden shape of thinking and can
actually predict students learning
better than test scores so the
traditional tests and grades that our
educators have pretty much long used
may measure
learning less accurately than these
scans of the brain according to this new
study at least daily dance exclusive for
you uh indirect signals of dark matter
might actually change depending on the
galactic environment how they come from
uh so
it might change where you look so this
possibility is
in this new study so to get a little
more technical this possibility is
basically demonstrated and modeled uh
where dark matter annihilates in the
light mediators whose branching
fractions depend
on the long-range force sourced by
ordinary matter right so this study also
posits that electromagnetic signals of
dark matter might actually arise and
only arise from the centers of galaxies
where just typical matter densities and
astrophysical background levels are
really high so this is pretty crazy but
rain water everywhere on earth is
basically unsafe to drink due to forever
chemicals uh present in them this new
study has found
so there's a large family of uh these
chemicals called our pyrphase which
don't occur in nature right uh they're
known as forever chemicals because they
basically don't break down in the
environment
uh and this research has shown these
chemicals are actually present in
rainwater globally and including in
remote locations like antarctica but
don't worry about that too much because
if you've been reading the newsletter
there's some good news about breaking
down forever chemicals which we'll get
to and for the second puzzle of the
video what did the scientists say when
he found two atoms of helium so over to
some climate news a new study uh has
basically said that catastrophic climate
change outcomes including human
extinction basically haven't been taken
seriously by scientists um
the author of this new study basically
said that the consequences of more
extreme warming which is still possible
if no action is taken to prevent it
uh are basically done dangerously under
uh explored so they they're basically
arguing that the world needs to start
preparing
for what they're
calling the climate end game and they
basically just want un scientists to
investigate you know the risks of
catastrophic change and according to
their new analysis the closest attempts
to directly understand or address how
climate change could lead to global
catastrophe basically come from popular
science books such as the uninhabitable
earth and not from like mainstream
research so in recent years climate
scientists have uh pretty much only
focused on the impacts of warming around
1.5
to 2 degrees above the temperature seen
in 1850s before the onset of global
industrialization right and uh these
researchers found that estimates of the
impact of the temperature rise of three
degrees are basically completely
underrepresented compared to their
likelihood i think it's just saying risk
management to uh think about the
plausible worst case scenarios uh and we
do it when it comes to every other
situation already so like why not do it
when it comes to the fate of the planet
and our species right right
understanding uh the plausible but you
know pretty grim scenario is something
that could galvanize both political and
uh civil opinion right and we saw this
when it came to the identification of
the idea of a nuclear winter and that
compelled the public efforts
uh you know just the disarm movements
through the 1970s and 80s so
now hopefully we can find some similar
concrete in clear mechanisms
for when it comes to thinking about
climate change that has a similar effect
on our world so over to some wildlife
news and basically the destruction of
sumatran elephants habitat is causing
them to be increasingly
pinned down in shrinking patches of
forest and they're getting chased by
every side and that's leading to an
increase of human elephant conflict as
these elephants are being
forced into more frequent encounters
with villagers who basically resent them
for destroying their crops and homes
and uh in 2016 there were only
268 resident uh asian elephants in
bangladesh right and more than 50 were
killed in the past five years with 34
being killed in 2021 alone so
you know saving sumatran elephants
starts with counting them and indonesia
won't even say how many are left
so i just wanted to get this news out
there and then i think this was the
first newsletter where i started
creating these uh
you know images at the end of the
newsletter to represent what we talked
about in them and so i've done this ever
since and this was the first one and so
this is using dali to
the ai
uh art generator so you basically type
in a word prompt and it you know gives
you something incredible and so i
thought this was pretty beautiful you
know sumatran elephants with some kind
of climate endgame scenario
uh pretty symbolic of things we talked
about and then so the answer to
those puzzles i gave you uh the second
one was hihi
and the first one was a light so if
you've got those good good stuff
that'll do for this video guys so make
sure you subscribe and i'll catch you
next time
