    Article Summary: Three quarters of victims of vaping reported using products containing THC. Health officials claim that the outbreak in vaping related lung illness say that THC plays a big role. THC is the active ingredient in marijuana. Most of the vapors reported getting their vaping supplies from informal dealers such as the street and friends. Doctors still don’t know what is truly causing the illnesses, but we have to rule out that the ingredients have to play a role. The principal director of the CDC says that they don’t if THC is the only risky ingredient for lung disease. Which is why they strongly suggest that they don’t use e cigs. So far eight hundred people in forty six states have come down with this illness and 12 have perished. 62% of the cases involve people aged from 18-34 years old and 16% of the patients are under 18. Most of the cases of illness are serious. Patients have used eighty seven different kinds of brands of vaping products. Sixty six percent of patience have used a brand called Dank Vapes which is a black market type of brand of vape. The company isn’t single and is unregulated. They have also found a pesticide called Myclobutanil in vaping cartridges from unlicensed and unregulated dealers. This can can turn into hydrogen cyanide when burned. The CDC encourages steering clear from using e cigs.

    Personal Reaction: I think that it’s crazy that the youth America are wasting away their lives with something as stupid as e cigs. I mean the chemicals (known) are shocking and I can’t believe that we are having a cigarette crisis all over again. It’s important that kids know the risks and the repercussions for falling slave to this extremely addictive trend. Quitting will be nearly impossible with the cigs containing ten times as much nicotine as one regular cigarette, and I predict there could be a mass genocide of people dying of lung cancer in the near future with all the younger people beginning to do this new trend. We already have 12 recorded deaths and this whole situation is fairly new.

    Article Summary: A trial runner was gored by a bison at Antelope Island State Park in Utah in June. He made a full recovery, but soon afterwards he brought a date back to the park and she also was gored by a bison. These incidents are quite rare, with 4 million people visiting the state park in the past ten years and only five bison attacks. When they feel threatened bison are more likely to fake charge. Since 1980, bison have injured people in Yellowstone than any other animal has. Most of the cases involve the people getting way too close to the animals to take selfies. The man was at the highest point in the park when he stumbled upon two adult bison. He than ran for it but couldn’t escape one of the bison’s charges. The Bison flung him into the air and then trampled over him leaving him with a cracked rib and a collapsed lung. When a bison is uncomfortable. A woman was charged and flung into the air by a bison in the same state park and they had to airlift her out with a broken ankle and a thigh wound. They both advise that in case of close contact with a bison to steer clear and to turn back the way you came. You can’t outrun a bison because they reach speeds of 35 mph and for being the largest mammal in North America they are also agile.

    Personal Reaction: I am in shock that this couple had luck this bad in that both of them have been struck by bison in the same park, and it actually makes for an interesting story. I can’t believe that people are stupid enough to get up close to an animal that in massive and dangerous just to take a good selfie. These animals are untame and should be spectated from a safe distance. I hope that people will read the signs and keep a safe distance and that stuff like this is minimized.

    Article Summary: Scientists have taught zebra finches to memorize songs by implanting the songs in the birds’ brains. They usually learn their songs from their dad. They created the experiment to find out the brain pathways that are responsible for note duration. They hope to find similarities between them learning new songs and how humans learn to speak. Their goal is to study the genes and neurons in the birds to help the vocalization with autism people. We have confirmed that regions control the behavioral-goal memories . A neuroscientist said that this is what helped them to implant the fake song memories in the birds. Toddlers and birds learn language the same way; by listening and repeating what they hear, and practicing the songs from the father bird. The scientists used optogenics to change the finch’s neurons without letting them hear the songs. By flashing light in a certain order they were able to encode the songs that would match how long the light flashed. This doesn’t teach the birds pitch in the song so it doesn’t sound the same as if the father taught it. Linking the HVC and the Nif parts in birds’ brains is important for singing. The communication learning pathways in a human brain is way more complex than in a finch’s but this is helping scientists learn how to treat neurodevelopmental disorders.

    Personal Reaction: I never in a million years would have thought we would be able to teach a bird a song by encoding it into it’s brain then using that research to study neurodevelopmental disorders. That sounds like something from the far future. That is complete genius and hats off to whoever thought of this. This seems like such an interesting topic and if we could somehow change the effects of autism it would be astronomical. I wonder how someone came up with this idea and I wonder how this affects the birds. This experiment sounds kind of cruel so I hope this doesn’t affect the birds’ too much.

  4. Title: This Bizarre, Eel-Like Shark Prowled the Oceans 350 Million Years Ago

    Article Summary: Scientists have recently discovered an almost complete skeleton of an ancient shark belonging to the Phoebodus genus. They are closely related to the modern day Frilled shark. They grew to be about four feet long and lived three hundred and fifty million years ago. This was way before dinosaurs and megalodon were on the planet. Before this study, scientists didn’t know much about what the Phoebodus looked like. Well preserved shark skeletons are rare because they are made of soft cartilage instead of bone which decomposes over time. The only evidence that these sharks ever existed were it’s unique three three cusped teeth until the scientists found and almost complete fossil of one. A member of an indegenous tribe in north africa found the specimen in the Moroccan mountains and brought it to a paleontologist. The fossils were well preserved because they were sitting in low oxygen conditions where decomposing organisms couldn’t affect them. The model shows that the fish had an eel like
    body and a long snout making it similar to the frilled shark. It also had a similar feeding strategy. The skeleton is missing a preserved tail fin which could help them understand how the beast moved.

    Personal Reaction: I can’t believe that the shark was only recently confirmed that it existed but scientists still believed even with only biological inference. This shark seems very frightening and It’s cool that they are able to compare it with modern day sharks. I wonder how they are able to calculate the age of the fossils and the soil rock they find it in? How do we know it is accurate? The fossil kind of looks like a snake or something.

  5. Title: This Microbe Is Spreading Antibiotic Resistance to Other Bacteria

    Article summary: Infectious bacteria is becoming more and more resistant to antibiotics all over the globe. This happens when bacteria mutates and then multiplies. They can be resistant to even the most powerful drugs. Now they are discovering that bacteria can pass on its resistance to other bacteria. A man had a serious bacterial infection and was treated and cured until a month later it returned. The team had no choice but to turn to the last line of defense antibiotics vancomycin. The bacteria was already ineffective due to resistance. The bacteria didn’t originally have a resistance to vancomycin but instead it had been given to. Patients with weakened immune systems suffer the side effects of antibiotics. When bacteria come together they exchange DNA information. Bacteria use CRISPR-cas9 system to cut up harmful DNA before it harms them. Antibiotics have increased life expectancy of twenty years across the world. We still don’t fully know which bacteria has resistance or not and are not completely sure how either. With each cut in the lab from E. faecalis we are one step closer to eliminating the quickly evolving pathogen. E, faecalis is a healthy gut bacteria and is extremely resistant to antibiotics. This could be deadly if contacted by harmful gut bacteria.

    Personal Reaction: I think that it’s important that we don’t overuse antibiotics and when we do that we make sure and kill it all with strong immune systems that can rebound. If we’re not careful antibiotics could lose their effect on bacteria completely and could pose serious problems. I hope that scientists figure it out one day and that doctors prescribing these powerful medicines are aware of the possible outcomes and their patients.
