Students are demanding change after the deadly Florida High School shooting.On Monday, a group of teens from Maryland held a lie-in near the White House to stand with the victims of last week's mass shooting.The group, called Teens for Gun Reform, held the lie-in at 12:15 p.m. between the White House and Lafayette Park. Demonstrators lied on the ground for three minutes to symbolize how long it took the suspected gunman to buy the AR 15 rifle used in the attack.Many students who survived the shooting are now speaking out against gun violence. They are calling for a nationwide student and teacher walkout on March 14 to demand tougher gun laws. There are also talks of an anti-gun violence demonstration in Washington, D.C. and other cities across the country on March 24."My message for the people in office is you're either with us or against us. We are losing our lives while the adults are playing around," said Cameron Kasky, a Marjory Stoneman Douglas high student who survived last week's shooting.  1050

Sudan, the world's last male northern white rhino, has died.For nearly a decade, Sudan lived in a 700-acre enclosure at the Ol Pejeta Conservancy, against the backdrop of the hulking Mount Kenya.Armed guards protected him 24 hours a day because he belonged to a subspecies on the verge of extinction from poachers. Rhinos are targeted by poachers fueled by the belief in Asia that the horns cure various ailments. 421

TEMPE, Ariz. — It's a huge breakthrough for the highly contagious and deadly norovirus as researchers at the Arizona State University’s Biodesign Institute have come up with a vaccine made from plants.The norovirus is known as the perfect human pathogen. It can have you feeling awful for days, but researchers at ASU say a form of the tobacco plant may be the key to a vaccine.Also known as the cruise ship illness, norovirus hits nearly 20 million Americans every year. According to Andy Diamos, a post-doctoral researcher at ASU, the average person has the stomach bug five times in their life.“Norovirus is a horrible bug to get,” said Diamos. “It causes vomiting, diarrhea, all sorts of nasty stuff.”There is no vaccine for the highly contagious bug because it's notoriously difficult to produce in a lab, until now, thanks to Diamos and Hugh Mason with the Biodesign Center.“Genetic engineering has allowed us to design systems like plants to produce useful things like vaccines,” said Diamos.By using a form of the tobacco plant, researchers discovered that a harmless bacteria would help grow a norovirus vaccine when the proper genes are transferred to the leaves.“You can basically put in whatever genes you want and transfer those to the plant, so that's how we get the plant to make the vaccine,” said Diamos.According to Diamos, real viruses are surrounded by a shell that protects its genes. The vaccine that grows inside the tobacco plant is essentially that shell without the harmful insides.“If you give that to someone as a vaccine, it looks just like the real virus, but there is nothing on the inside,” said Diamos. “It can't cause disease; it can't actually infect you.”That's what makes these plant-based vaccines safe and effective.“One of the main reasons why we're focusing on plants is because they're so cheap to work with. These vaccines will hopefully be much cheaper to produce than traditional methods,” said Diamos.Many discoveries from ASU researchers hit the market, this one could too, but it needs further study and would eventually need to be picked up by a pharmaceutical company which could take years. 2154

SYDNEY, Australia – Koalas are on track to become extinct in New South Wales before 2050, according to a report from the Australian state’s parliament.A committee released the report Tuesday after a year-long inquiry and it’s asking the government to take immediate action to save the nation’s most loved animal.A government estimate showed that there are about 36,000 koalas in the state, but the committee says that estimate is outdated and unreliable.The report says the loss in koalas is partly a result of the 2019-2020 bushfires that devastated the country. The committee says at least 5,000 koalas were lost in the fires over the past year, potentially more.“An estimated 24% of koala habitat on public land has been severely impacted across the state, but in some parts, there has been a devastating loss of up to 81%,” the report says of the wildfire devestation.However, the committee says the most serious threat to koalas is habitat loss.“The ongoing destruction of koala habitat through the clearing of land for agriculture, development, mining and forestry has severely impacted most koala populations in the state over many decades,” wrote committee chair Cate Faehrmann. “The committee found that this fragmentation and loss of habitat poses the most serious threat to koala populations and made a number of key recommendations that stronger action must be taken by government to protect and restore koala habitat on both public and private land.”The committee also found that climate change is having a severe impact on koalas, not only by affecting the quality of their food and habitat, but also by compounding the severity and threats of other impacts, such as drought and bushfires.Along with its findings, the committee provided a long list of recommendations for the government to implement in order to save the state’s koalas. Those included prioritizing the protection of koala habitat corridors, improving monitoring methods and increased funding.One recommendation encourages the government to look into the establishment of a Great Koala National Park on New South Wales’ North Coast. 2120
