Heat waves caused by global warming are killing off the corals of Australia's Great Barrier Reef, the world's largest reef system, according to a study published Wednesday in the Journal Nature. The Great Barrier Reef experienced an extended marine heat wave in 2016 that caused massive coral bleaching and die-off. Most of the impact was along 500 miles of the northern part of the reef. The reef endured coral bleaching in 1998 and 2002, but the northern region received only minor damage at the time.
Global heat and coral bleaching began to increase in 2014 and continued through 2017. This event means that marine heat waves causing bleaching struck three-quarters of the world's coral reefs and that the heat waves that caused corals to die struck almost a third, the researchers said. The 2016 marine heat wave caused the most severe and catastrophic coral bleaching event the Great Barrier Reef has ever experienced, the study found. Overall, these events have affected every part of the reef. "We lost 30 percent of the corals in the nine month period between March and November 2016," Terry Hughes, study author and director of the Australian Research Council Centre of Excellence for Coral Reef Studies at James Cook University, said in a statement. Without immediate care this great wonder on Earth will soon die out.

Hassan, a boy with a rare incurable skin disease deemed fatal has been the first to receive a potential cure for this condition. Epidermolysis bullosa, the incurable disease, has been defeated by this new treatment. This condition makes the victim’s skin as fragile as an insect’s wings, even the friction of clothing can cause blisters. By taking a 1 ½ inch piece of healthy skin, scientists can clone these cells and make a “replacement” for the sick skin cells. But, there is only a 50% chance this treatment will work. When scientists were replacing Hassan’s skin they were aware of the chance that his body might not accept the new skin cells. Now thanks to Muenster University hospital, Hassan can now play outside and have fun with all the other children. Hopefully they can solve the problem of the 50% chance that the patient’s skin rejecting the treatment.
In December, a girl with a rare disorder, Ectopia Cordis, was the first to survive undergoing treatment in the U.K. The condition, Ectopia Cordis, causes the heart to be born either halfway, or completely outside the infant’s body. The baby was delivered by 20 doctors. As soon as she was born she was rushed into 3 intensive surgeries. Talk about a Christmas miracle, just in time for the holidays!
I think it is great that scientists have gone through all this hard work to save these lives. Now, many other deaths will be prevented thanks to the discovery of these new treatments. What happened to these two children is the result of technological advances and hardworking scientists.

Aging has been a marvel of scientific questions, one unanswered for many decades. People may wonder if it is ever possible to reverse the aging factor that controls all of life’s cycle. According to Harvard and MIT scientists, yes, it is possible.
In a new study, researchers say they have reversed aging in mice, and that discovery could set the stage for similar results in humans. Dr. David Sinclair has spent his entire career focused on aging and now believes he's discovered a way to stay younger for longer. Dr. Sinclair notes that reversing of aging could help prevent devastating diseases such as cancer, heart disease, diabetes, and Alzheimer's. Most importantly, the entire human race could boost age expectancy.
So how did these scientists actually accomplish this feat of science? It starts with a molecule called NAD+, also known as nicotinamide adenine dinucleotide, which humans use to live. As we get older, the level of NAD+ in our cells drops, leading to DNA damage and the diseases of aging. Scientists attempted to boost NAD levels in mice in order to reverse aging symptoms by putting doses of NAD+ into the water of a few mice. Instantly, the blood vessels were “young” again, increasing blood flow and nutrient delivery, helping to make the cells much more healthy which led to an overall efficient body system. Within the first week, the scientists saw age reversal in muscle and improvements in DNA repair.
Scientists have a capsule proxy called nicotinamide mononucleotide (NMN), also found in your daily greens, such as broccoli, cucumber, and avocados. This is changed into another compound that allows mice to produce more blood cells that line their muscles. Studies show mice improved their treadmill run time by an astonishing 60% compared to animals that did not get the molecule. The most impressive fact is that mice were able double their exercise endurance which matched the same endurance levels of young mice!
The ultimate goal of Dr. Sinclair's results is to see the feasibility on reversing age of human tissues. Currently, he has started a company in Boston, called MetroBiotech, to test the experiments, ethically, on humans. If his tests prove positive, Sinclair aims to use NAD+ to provision age-related damages on a much broader scale, such as shielding cancer patients from radiation treatments or protecting people from higher radiation work areas.
Most of all, it is important to realize that these futuristic technologies do not necessarily mean we should depend upon them so much that we forget to take care of ourselves. Reversed aging is for those who potentially need it to survive. Normal citizens should not use NAD+ doses for personal joy or alternatives. People should follow a healthy lifestyle and diet that will inevitably increase productivity and give an aesthetic health value.

The future for cars is endless. We will even have flying cars. Two of these cars are Uber and AAV, a car made in Dubai.
On April 25, 2020 Uber will be putting a flying car on the market. Los Angeles paired up with Uber to build the car and so did Dallas and Dubai. Also Uber has signed a Space Act Agreement, which means that Uber and NASA have teamed up to make a new air traffic control system. Pairing up with NASA was a big deal because it guarantees Uber’s participation in NASA’s unscrewed traffic management (UTM) project, which was first introduced in 2015 to regulate drone traffic which has become a big problem. Uber released a video demonstrating what the new aerial taxi service is like.
The name of Dubai’s flying car is called Autonomous Aerial Vehicle (AAV). There was even a man that rode in it as a passenger. Dubai also has flying taxis. The AAV is the safest, smartest car yet. If any components malfunction, the car will immediately land in the nearest possible place to ensure safety. Flying cars are set for takeoff at Tokyo's Olympics in 2020. Volvo, Toyota, and Tesla are also competing to launch a flying car in 2020. British made flying cars can be in the air by 2020 but they definitely won’t be cheap. The cars will cost 1.5 million euros which equals 1,855,740 US dollars. 100 orders have already been placed on the British made cars. The future of driving looks like it will be up in the air! We’ll see!

High in dense bamboo forests in the misty, rainy mountains of southwestern China lives one of the world's rarest mammals, the giant panda, also called the panda. Only about 1,500 of these black-and-white relatives of bears survive in the wild.
Pandas eat almost nothing but bamboo shoots and leaves. Occasionally they eat other vegetation, fish, or small animals, but bamboo accounts for 99 percent of their diets. Pandas eat fast, they eat a lot, and they spend about 12 hours a day doing it. The reason: They digest only about a fifth of what they eat. Overall, bamboo is not very nutritious. To stay healthy, they have to eat a lot—up to 15 percent of their body weight in 12 hours—so they eat fast.
Pandas' molars are very broad and flat. The shape of the teeth helps the animals crush the bamboo shoots, leaves, and stems that they eat. They can chomp on bamboo up to one-and-a-half inches thick. To get the bamboo to their mouths, they hold the stems with their front paws, which have enlarged wrist bones that act as thumbs for gripping. A panda should have at least two bamboo species where it lives, or it will starve. A scarcity in bamboo threatens the already limited panda population.
An adult female panda weighs 200 pounds. Pandas can climb as high as 13,000 feet and are also very good swimmers. Sometimes male pandas relax by doing handstands against trees.
Pandas are shy; they don't venture into areas where people live. This restricts pandas to very limited areas. Pandas are endangered. One main reason that they are endangered is that humans are destroying their habitat. By doing this, pandas have to go into smaller places to live.
All in all, pandas are a great species of animals and we have to help them! I mean, who wants baby pandas to die?!
