The Blood Harvest

The Blood Harvest | An Always Evolving Biological World | Scoop.it
Each year, half a million horseshoe crabs are captured and bled alive to create an unparalleled biomedical technology.
Qiana Sweet's insight:

The horseshoe crab may seem insignificant to us, but they are quite valuable in the research that takes place every day. Their immune system is many times stronger than ours because of the chemical component in their blood. Our blood is iron-based, theirs is copper-based. Our blood is red because of hemoglobin and theirs is blue because of hemocyanin.  The chemical component in their blood, coagulogen, can detect the slightest trace of a bacterial presence and trap them.

 

In the past, horseshoe crabs were steamed and ground for fertilizer, and later used as live bait to catch large snails. More recently, scientists drain about 30 percent of the horseshoe crab’s blood and returns it into the ocean, far away from where it was found in order to avoid draining the same crab more than once. Most of the crabs don’t die, but the draining still has negative effects on the crabs.

 

Seeing as this a PBS Nature documentary, and the presence of historical evidence of the uses of the crabs along with the more recent discoveries, I consider this a credible source. I know that the knowledge of the chemical component in the horseshoe crab’s blood is more than enough reason for scientists to perform lab tests and experiments. The components of their blood could lead to extraordinary discoveries. Reading this makes me wonder just how the chemical component in their blood could affect the diseases we test it with. Maybe these experiments could possibly lead to cures, or get us closer to them.

Scientists will attempt to clone a 43,000 year-old woolly mammoth | News | Geek.com

Scientists will attempt to clone a 43,000 year-old woolly mammoth | News | Geek.com | An Always Evolving Biological World | Scoop.it
An international team of researchers in Yakutsk, Russia are currently examining a remarkable specimen — a 43,000 year-old woolly mammoth. The animal was discovered last year embedded in a block of ice on [...]
Qiana Sweet's insight:

I find a preserved mammoth to be a very significant discovery in our lifetime. We have only ever seen mammoths in pictures and simulated ones in movies, but now we have the option of cloning one in order to better understand them. This excites me and worries me at the same time. I’m excited because many of us may one day have the chance to see a creature that we never would’ve thought we would be able to see.

 

However, I’m afraid and worried because woolly mammoths were known to be dangerous when they were hunted, so I’m not sure how a hybrid one would respond to its new environment and to the animals around it. We have no idea what to expect when doing these experiments and it could put the other animals, as well as mankind, at risk and expose them to harm. Also, what would become of this hybrid species? I saw splice, and even though it may be a fictional movie, it was quite believable! What if the hybrid elephant/mammoth didn’t have any of the expected characteristics? One can only imagine the possibilities.

               

I could definitely call this source reliable. Ryan Whitwam reported on a discovery made by scientists in Russia. These discoveries are not very uncommon because their bodies are found fairly frequently in Russia. His report is based off of the report of the scientists and his only real commentary is based upon the article about the scientists’ discovery.

Electronic noses for early diagnoses of diseases by smell - Updated News

Electronic noses for early diagnoses of diseases by smell - Updated News | An Always Evolving Biological World | Scoop.it
Electronic noses for early diagnoses of diseases by smell
Updated News
Bad smells exist for a reason, agrees Val Curtis from the London School of Hygiene & Tropical Medicine. “The disgust ...
Qiana Sweet's insight:

I believe this source is credible because it is simply a reported documentation of the studies of various teams of scientists and doctors working towards a common goal. The science behind the technology we have today will be even better tomorrow. Technology evolves rapidly and each of the discussed devices has proven that.

 

Having the ability to smell a particular disease just by being near a person can make all the difference in saving their lives. The earlier we can detect the diseases, the earlier treatment can begin. The e-nose in particular doesn’t just make it easier to detect diseases such as breast cancer, it’s a more comfortable method for women who receive annual mammograms.

 

The ability to monitor these diseases outside of the body and doctor’s office is a brilliant achievement in my opinion. It’d be like technology Vitamin C, helping to fight infections and aid our immune system in getting stronger.

 

Technology serves to make our lives easier, which is why we have cordless and portable phones. We install plenty of apps on our phones for our various needs and wants in everyday life. With the presence of e-noses, and similar technology, we can always stay on track of our health as well as the wellbeing of others.

 

Knowing that test results can come in as soon as ten minutes, as opposed to two weeks, can give patients a sense of security. Two weeks can be a lot to bear and can cause anxiety and stress levels to rise until they get the phone call they’ve been waiting for. If this type of technology were installed on phones, imagine how much money people could save by only going to the doctor when they need to. I can only imagine there will be a hefty price for such technology, alone and installed in a cellular device. I personally think the investment is well worth it.

‘Digital dementia’ for our screen-addicted kids

‘Digital dementia’ for our screen-addicted kids | An Always Evolving Biological World | Scoop.it
The national obsession with all things digital, from smartphones to online games, has some health experts worried about kids today — especially their brains.
Qiana Sweet's insight:

Did you know that the under stimulated neurons in your body are gotten rid of? According to this study, children who spend too much time on the computer (this includes surfing the internet and playing computer games), as well as too much time watching television, can eventually begin to experience trouble with memory and thinking. Allowing other devices, which are of convenience for us, to think for us doesn’t allow our brain to be stimulated because we don’t have to remember anything when we can Google it.

 

I’ve always known the effects of too much technology, like vision being affected, lack of sleep, and obesity, however I would not have known that it could impair learning when so many of us use it for learning. I even use my phone, not only for entertainment, but also for educational purposes. I watch how-to videos for various classes and I also use my tablet for taking notes in certain classes. The world of technology at our fingertips intrigues me and prompts me to learn more about what’s out there and tell people about it.

 

Technology, I have always thought, could help stem creativity and offer up inspiration and encouragement. It depends on how you view it and how you use it. If we take a look at how much time some of us really spend on games and social media, compared to how much time we spend working and other similar things that stimulate our minds in that way, it may be disproportionate.

 

The sources of the article itself are doctors of various fields, including psychiatrists, neuroscientists, and pediatricians. I feel as if the doctors have been in their field of study for quite some time in order to draw these conclusions, making them more credible.

The nanotechnology in your sunscreen

The nanotechnology in your sunscreen | An Always Evolving Biological World | Scoop.it
Nanoparticles prevent skin cancer by absorbing UV light, without making your face feel 'cakey'. Here is how they do it
Qiana Sweet's insight:

How often do we really think about what’s in the products we use daily? Sunscreen contains nanotechnology that heavily relates to chemistry. Zinc oxide and titanium dioxide can reflect and absorb cancer-causing ultraviolet rays. These compounds clump together when they’re mixed inside the sunscreen but still retain their highly reactive UV light-absorbing capacities.

 

The metal oxide nanoparticles cannot penetrate any further than the outermost dead layer of our skin, making them more helpful than harmful to us. Our immune cells even collect and break down zinc oxide. Although this has been stated, the researchers know that their statements need to be tested more to make sure they hold true.

 

Holly Cave appears to be a credible source. She has taken time to research in detail the things that most people would barely scratch the surface of. Seeing as I am allergic to sunscreen (my skins breaks out pretty bad) I would never have known what was really in it, past the ingredients label – which I never read. It leads me to wonder what it is that causes me to break out when I wear it.

 

From what I do know is that the sun’s rays target dark spots – of course dark colors draw heat. When I went to the dermatologist I was told this. Does this also mean that sunscreen is especially effective when applied to dark spots? I’m not sure but it’d be some interesting research to do. Looking into how our skin really works could help us better prepare for the weather, besides just looking at how hot or cold it will be outside.

Veterinarian offers acupuncture for pets - Aurora Beacon News

Veterinarian offers acupuncture for pets - Aurora Beacon News | An Always Evolving Biological World | Scoop.it
Marty Hoover’s cat Madeline was very sick. “She had stopped eating and was really thin and weak,” the Aurora resident recalls. “I took her to my vet who gave me some medications, but after I gave Madeline one of each tablet, she had terrible diarrhea.”
Qiana Sweet's insight:

Dr. Judy McBeth is such an inspiration to me, an aspiring veterinarian. I find her to be a very credible source because not only is she a professional at Fox Ridge Veterinary Clinic in Oswego for more than twenty years, so she knows what she’s doing. She has also been practicing acupuncture for almost a year now. People know her and bring their pets to her regularly which lets me know she has crafted her credibility very well and people know they can count on her for good advice and to keep in mind the wellbeing of their pets.

 

Traditional medicine is all I ever knew animals could take but this discovery makes me want to try it once I open my own clinic! When I read the portion of the article facial paralysis I could only think about what this could mean for the animals that suffer with arthritis. Being able to combine modern medicine with acupuncture, which was used over 3,000 years ago, could open up new medical pathways for not only animals, but humans as well. I can only imagine that if someone who was paralyzed could receive these treatments so that scientists could see how the human body responds. If acupuncture works for facial paralysis in animals, I wonder what wonders it could work for humans.

 

Whenever a new medicine is created to deal with illnesses, there are more often times than not, undesired side effects. Acupuncture has the ability to reduce the severity of those side effects by simply inserting very thin needles where the nerve endings interconnect, so it’s virtually painless and at the same time your nerves are stimulated to produce the desired effect.
