other items. authorities say that they arrived on the scene quickly and have several leads. they add that this is the latest flash mob burglary in the area in recent days. it was a beautiful weekend for star gazing in the vulcans. this shows streaks of light from the percseid. how lovely. nasa says this occurs when earth passes through the trail of a comet. and particles from the comet interact with at not fear causing the bright streaks of light in the sky. and also in space, there is a question mark deep in the galaxy. a shape of a question mark was captured last month.
spectacular display. i didn't see very many, it was quite cloudy where i was yesterday, so i didn't see too many, but i did see a lot of light pollution. you can get up to 100 or so per hour, as you say. they can be quite small between expected from shooting stars and meteors. unless you live somewhere or can get somewhere with the dark skies, with light pollution in the city, you're unlikely to see very many and that was the case with me last night, unfortunately. for anyone who doesn't know about the perseid, tell us a bit more about it. what is it and why exactly does it happen? it happens pretty much the same time every year as particles from the sun in its orbit is almost circular, and we pass through the debris that was left behind when comets pass through the solar system. this particular one doesn't come across very often, an orbital period of 133 years.
Physicists are using quantum computers to conjure various exotic phenomena and are claiming that their creations are truly real. The work is forcing us to ask challenging questions about the nature of quantum reality
one theory is that the particles are in the air, can get in your lungs and bloodstream. they may carry some bacteria around, making them more -- making people more susceptible and increasing resistance. it could be that there is more infections as a result of those bacteria going around. more people than using antibiotics and that increasing resistance to those antibiotics. don't know for sure. but it is a strong correlation. these two seemingly unlinked things. >> how long has this been a problem? >> yeah, you know, this is interesting, poppy. people think about antibiotics. when was penicillin even discovered? you know, it was not even 100 years ago, right? so there was antibiotics before that in 1909. penicillin discovered in 1928. first used in 1942 because it had to go through all these trials. within five years, you had antibiotic resistance to penicillin. some evidence of it. so it can happen very quickly.
infection issues diseases more dangerous dr. sanjay gupta joins us now. good morning. so, people may not necessarily -- by people, i mean me. >> and me. >> okay. may not understand the link between these two. so, explain them. >> so far, this is a correlation study. there is no direct cause and effect here. but it's a strong correlation. as you see places in the world where you have more air pollution, you also find more anti-my koeb result resistance. s pollution goes goes up, it goes down. they saw this in some 166 countries around the world. so now the deeper investigation begins. what cexactly is going on? a couple theories. when we talk about particles, these are less than 2.5 microns in size. to give you an idea, human hair is 50 to 70 microns in size.
we see this feedback loop of warmer oceans contributing to those warmer temperatures on land and we saw the link there with those extreme heat waves over the past weeks and months that many of the world has been suffering through, and the other thing to mention here is of course hurricanes. all motions are directly linked to more frequent storms and stronger hurricanes and of course, scientists are now bracing for the start of the atlantic hurricane season. what are scientists _ atlantic hurricane season. what are scientists saying _ atlantic hurricane season. what are scientists saying about - are scientists saying about what is behind this marine heatwaves?— heatwaves? yeah, it's interesting _ heatwaves? yeah, it's interesting because i heatwaves? yeah, it's. interesting because they heatwaves? yeah, it's- interesting because they don't have an exact answer right now. there are a lot of factors at play. one of them is a theory about dust and sand from the sahara desert. so normally, strong winds will bring fine particles of dust and sand from africa across the atlantic ocean and those serve is almost tiny reflectors, pouncing somewhat and heat back into the atmosphere and calling down the atlantic ocean. those winds have not been blowing as much
lake with the extreme heat waves in the past weeks and months many of the past weeks and months many of the world has been suffering through. the other thing to mention it's of course hurricanes warmer oceans are directly linked to more frequent storms in stronger hurricanes and of course scientists are now bracing for the start of the atlantic hurricane season. what are now bracing for the start of the atlantic hurricane season.- atlantic hurricane season. what a scientist saying _ atlantic hurricane season. what a scientist saying about _ atlantic hurricane season. what a scientist saying about what - atlantic hurricane season. what a scientist saying about what is - scientist saying about what is behind the heat wave? it is interesting _ behind the heat wave? it is interesting because - behind the heat wave? it 3 interesting because they don't behind the heat wave? it 1 interesting because they don't have an exact answer right now. there are an exact answer right now. there are a lot of factors at play. one of them is a theory about dust and sand from the sahara desert so normally strong winds will bring in fine particles of dust and sand from africa across the atlantic ocean and those served as almost tiny reflectors bouncing sunlight and heat back into the atmosphere and cooling down the atlantic ocean. those winds have not been blowing as much this year. that could be part of the reason. the other concern is of the reason. the other concern is of course el nino which is a warming
the most supply of tinfoil in the most supply of tinfoil in the world. most famously cern is home to the largest was my biggest machine built to examine the universe's smallest particles. it splashes them together at almost the speed of light. the last time i was here, it made me cry. cern let us do science _ here, it made me cry. cern let us do science but _ here, it made me cry. cern let us do science but no _ here, it made me cry. cern let us do science but no individual| us do science but no individual country can do by itself. we can build fantastic machines, big, complex projects whether outcomes together to do it. the thing about _ outcomes together to do it. the thing about this place is the study don't like stuff that goes on here is highly theoretical and experimental and it kinda feels really abstract. not really relevant to our everyday lives. but plenty of stuff that's been developed she has filtered down to the real world. the
most expensive material in the known universe. anti— matter! it is the stuff of science fiction that turns out to be science fact. 0ur universe is made of tiny particles of matter and in theory every type of particle as an equivalent anti— particle. an evil twin thatis anti— particle. an evil twin that is the same in almost every way. but the thing is, there is almost none of it in there is almost none of it in the known universe. which is actually quite a good thing. because anti—matter and matter do not get along. so what happens when matter meets anti—matter? happens when matter meets anti-matter?— anti-matter? well, they are incompatible, _ anti-matter? well, they are incompatible, they - anti-matter? well, they are l incompatible, they annihilate each other and release the budget energy or other particles. it's a microscopically nasty business. yes, that's an understatement, can we say. the enormous release of energy when the two
