been tackling blazes in germany. question, how do you attract the right fish to your net? we will shine the light on a colourful solution. oh, look at that, pennies from heaven. and. take a feel. you can feel the texture. it s really soft. yeah. that s not what you need from a crisp. we ll find out why it s crunch time for al. it is an inferno and it s leaving little in its wake. we ve seen wildfires raging across many countries over the summer months. the hot, dry conditions exacerbated by climate change are making them more frequent and more intense. and it can often be a real struggle to bring them under control. high tech solutions are changing how we tackle them, whether it s drones dousing the fires or satellites predicting their spread. and paul has been to a forest near berlin to find out how one company is trying to prevent forest fires from taking hold in the first place. it s conventional wisdom that the earlier forest fire can be stopped the better, but often a fi
to prevent forest fires from taking hold in the first place. it s conventional wisdom that the earlier forest fire can be stopped the better, but often a fire can already be well established before it is noticed, making it harder to put out. but one company in germany believes it has a possible solution by using internet of things, sensors and alto understand what forest fires smell like. the basic function is like an electronic nose that we put into the forest and it can actually smell a fire. we can detect fires during the smoldering phase. so a few minutes after someone has thrown a cigarette, we should be able to ring the alarm bells. every forest fire has a unique aroma based on what surface material is around. i love that smell. yes. their forest ecology expert, dr. juergen mueller, collects these samples from around the world and then burns them to generate the data to train the ai on what an actual fire in a specific location may smell like. ok, now, we closed the cha
the sensors every 100 meters in more remote areas and 15 meters near well walked paths. so it looks like quite a lot of smoke coming off there. would that be enough already for your sensors to to be able to detect? that is enough for our sensors. so this smoke needs to reach the sensors, that means if the sensor is close to the smoke, for example, on this tree, then you have it within seconds. but it s notjust the eye and the sensors that are innovative. there s another problem that needed solving. we re here in a forest, in a rural area where i imagine there isn t much mobile signal. how do you get the data from the sensors out to where it needs to go to? because mainly there is no internal telecommunication infrastructure in the forest, we bring our own telecommunication infrastructure to the forest. so this is the mesh gate. oh, wow. okay. yeah. these mesh gateways needs to hear over the air. if one of these sensors in the forest has an alarm or a signal and so on, and the
hi, everyone. i m jessica dean alongside boris sanchez here in washington, d.c. and for the first time since the hamas terror attack on israel a small number of civilians are being allowed to leave gaza and escape the several hundred strikes a day by israel on hamas targets. egyptian state affiliate media reports the first group of foreign passport holders has arrived into egypt through the rafah border crossing. and sources are telling cnn the opening is the result of a deal mediated by qatar among israel, hamas and egypt. a senior u.s. official says this deal could ultimately lead to about 7,000 people allowed to cross. stressing that total, though, is far from exact. and just minutes ago president biden posted on social media that some american citizens are going to be among those departing gaza as soon as today. he hailed u.s. leadership and efforts to help some gazans and foreign nationals leave amid what is obviously an escalating ground offensive in the north of gaza
we continue here at cnn, our coverage of israel at war. you re most welcome, wherever in the world you re joining us from. i m richard quest in abu dhabi. here the time is 1:00 p.m. it s a few hours earlier in gaza, 11:00. they re two hours behind in gaza. and idf helicopters have been seen flying along the israeli coastline. these are pictures from ashkelon earlier today. now, ashkelon is only 20 kilometers from gaza. it is there, of course, that the idf says hamas has been is holding 230 hostage. and it is there where israeli military says it s hit more than 450 targets in the last day. israel says it includes hamas command centers, observation posts, and missile launch sites. first, let me update you with events overnight. these are the pictures israel says it s been targeting hamas tunnels and underground spaces, continues to urge everyone to go further south. in gaza itself, the near-total communications blackout apparently is easing, hospitals resume to be overwhelm
