In the eastern United States where the campaign for gun controls in response to the Florida School shooting has produced some extraordinary scenes. In tallahassee, the state capitol, students gathered to demand never again and tough restrictions on weapons sales. Then at the white house, President Trump convened a televised listening session where survivors and their families spoke of their anguish. Jon sopel reports from tallahassee. A school trip like no other. These students from Marjory StonemanDouglas High School have not come to the Florida State capitol to listen, they have come to speak and demand change after 17 of their classmates and teachers were killed last week. And they are determined to be heard. No one needs these weapons that are taking childrens lives. They should ban them because all they are used for is destruction and they are just not needed. You should go to School Feeling safe and be confident you are there for an education and a bright future, not worry about getting shot. Chanting never again neveragain the students werejoined by thousands of others from across the state, noisy, determined and emboldened. Chanting the nra has got to go the streets are literally echoing to the sound of these young people demanding gun control. But last night, state legislators voted against even opening a debate on semiautomatic weapons. The fight for gun control is going to be an uphill struggle. Chanting this is what democracy looks like but that decision not even to debate guns in the state assembly has infuriated pupils, teachers, and Community Leaders alike. I have buried in the last four days, three kids from my congregation. I watched a father want to climb into the mausoleum with his son. I watched a mother curled into a ball and refusing to come out for the family. Then they have the gall not even to discuss the issue, i am very upset. From the white house, small but significant signs of movement and the president has been meeting students and teachers, notjust from florida, but from other shootings as well. We want to be strong on background checks, very strong emphasis on the Mental Health of somebody, and we are going to do plenty of other things. This heartfelt plea from one of the parents. We cant forget about it, all these School Shootings. There should have been one School Shooting and we should have extinct and i am bleep . Because my daughter, i am not going to see ken. Again. These students have captured public attention with their demand for change, but it is a tough journey and winning support is a different thing to winning reform. More on that story in a moment. First, some of the days other news. The un secretary general has demanded an immediate end to fighting in the syrian rebel enclave of eastern ghouta, describing it as a hell on earth.

Its caused by a combination of high humidity and very low temperatures. Ice crystals coated the tree tops, while a sea of clouds shrouded the mountain. Lets get more on our main story now. President trump has been meeting survivors of last weeks School Shooting in florida. David willis is our correspondent in washington. 0ne one of the ideas being floated around is to basically give staff and faculty members opens in School Campuses . Yes, and donald trump bringing this up, conceded that it was a potentially controversial proposal on his part. But the plan, as it would stand, would be to teachers, some teachers who had training with guns and other members of staff, to be armed on School Campuses. President trump said that it took on average between five and eight minutes before so called First Responders to react to reports of a School Shooting in the United States. He said that that could be mitigated by teachers and other officials on the School Campus being armed. He called for an end to so called gun free zones. And an end to the concealed carry that exist in certain states here in the United States. But we heard as well from a pa rent of states. But we heard as well from a parent of a young boy who died in the senior took massacre, the School Massacre a few years ago. He said, his name is mark bardon and his wife isa his name is mark bardon and his wife is a teacher, he said teachers have quite enough to do in the classroom is already apart from taking on the role of vigilantes and he said this could only lead to shoot outs on school premises. Resident trump has promised a range of measures and has said that he will fix this problem. Pa rents said that he will fix this problem. Parents and students report of this listening session in the white house, what do the others have to say . Yes, we heard some displays of raw emotion, as you can imagine, on both the part of the parents and the student. Many of those students had seen those classmates gunned down before their eyes just a week ago. We heard from an 18 year old who lost his best friend in the Florida Shooting and he said, quite simply, i dont understand how anyone can go into a store and buy a weapon of war. How is it that it is so easy to buy that sort of weapon here in the United States . A lot of raw emotion, a lot of tears at the white house today in front of President Trump. Thank you so much for that update. David willis in washington. The hong kong pop star denise ho has told the bbc she has been denied a performance permit in malaysia over her views on gay rights. Homosexuality is illegal in the country and a minister has said artists have to comply with what he called local values. Kathryn armstrong reports. Denise ho has never been afraid of standing up her beliefs. She was once one of the biggest stars in hong kong, but everything changed when she became one of the faces of the 2014 pro democracy protests. That saw her blacklisted in mainland china, with some major brands pulling out of promotional projects with. Now she has been barred from holding a concert in malaysia this april for a different reason. We received a call from our co organiser in malaysia and they told us that our visa was denied and my visa was denied, and the reason that the person from the government gave was that because i was an active supporter of the lgbtq community. The malaysian government minister has not confirmed the ho visa was denied. But the communications are multi media minister said. Homosexual activity is illegal in malaysia and a recent crackdown on the Lgbt Community has been seen by some as an attempt by the ruling party to appease religious hardliners ahead of election in the coming months. Ho came out publicly as a lesbian in 2012, said she is disappointed but the decision is not a complete surprise. There were several cases where people had been denied visas for concerts and also a year ago, joshua wong, of hong kong, was also denied entry because of his support in the Umbrella Movement, and so i guess, because of my double taboo identity, because i was also a supporter of the Umbrella Movement and pro democracy, somehow we have guessed that maybe i would be denied access. Ho said malaysias decision wont hold her back and has vowed to continue fighting for the rights of the lgbt committee. Youre watching newsday on the bbc.

Tim allman, bbc news. Experiments by nasa to grow wheat in space are inspiring scientists in australia to see if itll work on earth. By changing how much light plants get, they can speed up crop cycles by over 50 . Its of massive importance since the world has to produce up to 80 more food by 2050 to feed 9 billion people. I spoke to dr lee hickey, Senior Research fellow from the university of Queensland Centre for crop science to find out how nasa inspired the research. Yeah, youre right, we were originally inspired by nasa, and they were trying to grow wheat in outer space, i guess as food supply for astronauts. But the way that they were doing it, they were exposing the wheat plans to continuous light so the plants did not sleep and it tricked them into producing seed very quickly, much faster than normal, and we thought what a cool tool this could be to speed up the rate of improvement of our crops here on planet earth. Now, as you say, its a cool tool. Can you describe this technology and is this something that any farmer can use . Well, its certainly a tool for plant breeders who are developing these improved crops for farmers to grow because we need these crops to be more productive, in the face of climate change, so thats warmer temperatures, more frequent droughts, rapidly evolving diseases, and even making them more nutritious as well, for humans to consume. But the way it works is that we expose the plants to 22 hours of light, and we can go from seed to seed in just eight weeks, thats for wheat. It also works for a whole bunch of different crops like chickpeas, canola, barley, some of the biggest crops that we grow in the world. This technique can allow us to achieve up to six generations of crops per year instead ofjust one in the field. Now, youre saying youre exposing these plants for 22 hours of light so how about the health of these plants . We know theres a lot of controversy still over genetically modified plants, anything that interferes with the natural process of a plants growth. So wouldnt reducing the sleep or rest that a plant gets damage them somehow . Yeah, well, actually, interestingly, umm, when we first proposed this very radical idea to some of our colleagues, they were very sceptical. They thought, oh, if we stress that plans out and give them this extra light they will be very weedy, only produce a couple of seeds, but, in actual reality, the opposite occurred and the plants resemble the ones in the field, very productive, and some of our experiments that we just published demonstrate that the plants often grown under speed breeding conditions are more productive than the plants growing in the regular glass house. So this is very promising, not only for plant breeding and developing crops but also, we suspect, there are some big implications for boosting in productivity in indoor farming systems, like vertical farms. Very briefly, though, of course, were not seeing the suns energy being utilised here, were seeing a lot of led lights, so this is going to take up a lot of electricity. That is certainly one of the main challenges with this technology. For people to adopt it they need the infrastructure, they need these controlled climatic conditions, but, youre right, theres been huge advancements in terms of lighting technology. We are now using leds that emit these special wavelengths, only the wavelengths that are needed for the healthy plant growth. And so this is saving a ton energy when it comes to cooling or heating the environment as well. Speaking earlier to my colleague, Sharanjit Leyl.
