Radioactive Babies Oh No!
I just read something very disturbing in this article. According to recent studies done in Germany, Switzerland and the US, researches have found that radiation has had an effect on the sex of babies born. Ever since the U-bomb there has been some concern. And as it turns out it's not without cause. Studies show that radiation exposure causes men to father more boys.
This honestly scares me. I know that radiation has caused birth defects, but even in these small doses it seems to be causing problems. If this gets too bad there could be a dramatic drop in females born. This is one of the many prices we must pay for our industraial society. I sincerly hope that we try to do something to prevent or help this situation.

Reindeer are use the UV rays to their advantage, it helps them find
food. Reindeer have can see more than 400 more wave lengths than us,
humans. They can also see in almost darkness. Reindeer have very keen
eyes.
I find this very interesting. I did not know that eyes were that
different. I knew dogs could only see certain colors and some people
could be colorblind. I think that this is quite cool. I guess it is
all really about natural selections, those with better eyes move on.

E. Coli bacteria on Organic Vegetables
I think that since E.coli, in this case could lead to other problems that people should somehow try to prevent this. Maybe manure could be tested for E.coli bacteria and if positive be thrown away or treated for it. If possible, organic vegetables could just be washed extra well before distribution. E.coli can probably get nasty and if it has killed people and a spread is going around then, something should be done to stop it if they know the source.

NASA is not a quitter.
http://www.nytimes.com/2011/05/25/science/space/25rover.html?ref=science
NASA reported on Tuesday, May 24th that they were stopping the efforts to reconnect with Spirit. It has been stuck in a sand trap for about two years since last winter. Spirit, one of the two rovers on Mars, had engineers hoping that when spring arrived so would the connection. But when spring came, the connection was still lost. Now NASA is coming to the conclusion that spending more money and time on Spirit is a waste. This thought has came to the ending of signals and communication with Spirit, the last message was sent last Wednesday.
I think NASA should not be called a quitter. I can agree both parts of this story though. I understand that NASA will now be saving money and time, so they can now benefit another study, but I also think NASA should at least explore all their options. If they stop sending signals to Spirit, why not create a new rover and spend the money on that rover? NASA should be open minded and I think they are handling this disappointing operation very smoothly. People should understand that the scientist and engineers worked very hard on Spirit; people need to stop hating, NASA is not a quitter.

Brain scans reveal why some people feel your pain
Some people can feel your pain but in their bodies. This might not make much sense but according to scientist, who have done brain scans on people who haven't lost any limbs on their body's and then do test on people who have, they found something strange. They found that people that have lost limbs like their arms or legs feel "Synaesthetic pain" which is feeling pain in a limb that is no longer there. This pain is imagined and it happens from seeing or hearing things that could harm someone. When someone observes or imagines pain, it activates parts of the brain which makes you feel like the pain is real.
Example:
"When I hear my husband's power tools, or see a knife, I often get a sharp pain through my phantom leg," says Jane Barrett, who has experienced synaesthetic pain since losing her leg in a motorcycle accident.
Opinion:
I chose to write about this summary because i thought it was unique how disabled people can still feel pain in limbs that they no longer have. I would hate to see a knife and get sharp pains where my limb used to be. This shows that scientist are learning more and more everyday about the human body and soon they will have answers for almost anything about the human body. This could help doctors and any kind of person who has a career that has to do with the body of humans and maybe even animals. I would recommend this article to any person who has lost a limb and gets those sharp pains when they see someone hurt or see something that could hurt someone, so they can learn why it happens.

This blog is about scientists growing nerve cells from skin cells in a lab dish. They first tried it with mouse cells and the conversion worked. For the human conversion, you need to add four more genes to the skin cell. This is a major breakthrough for people who have had a stroke.
I never knew that nerve cells could be regenerated. I personally would have not thought about just adding more and more genes to the skin cells to make them into nerve cells. I think this stuff is cool and the fact that we are actually accomplishing these things is even cooler.

Reindeer can see ultraviolet light
It has recently been shown that reindeer are able to see ultraviolet light. This is to prevent them from having what is called snow blindness. Snow blindness occurs when our eyes' lenses absorb UV light, which causes a temporary blindness. This was shown not to be a problem with reindeer because they are able to see ultraviolet light, so it isn't absorbed by their lenses. This prevents snow blindness and allows them to see even in the worst of conditions.
This is a very interesting discovery. Ultraviolet light is not within the visible light spectrum, so I assumed that animals in general, not just humans, couldn't see outside of the visible spectrum. I don't know that this discovery will lead to any further knowledge or exploration in vision of other animals, but it was interesting to read about. I am not sure if this test has been performed on other animals that live in the arctic, but it would be good if we did. I am glad I read this article, it was good.

Reindeer can see in a world of Ultraviolet light
I think reindeer use this or see in ultraviolet due to the fact that they live somewhere when the snow reflects almost 90% of UV rays. Humans don't always live in the Artic so there is no reason for our eyesight to change or adapt. Questions have arised from researchers how reindeer can eyes are not damaged, but our would if we looked at UV rays. I think the answer is because humans simply don't use or need UV to survive. Our eyes could be weaker and less tolerant of the UV rays due to that fact we don't use it everyday, while the reindeer has strentghened its eyes and lived off of this tatic to live.

Increasing Acidity Levels in Oceans Cause Troubles for Marine Life
Drug Combo can cause Diabetes
A recent finding of a drug combination, one being an antidepressant and the other being one to lower blood cholesterol may cause people to develop diabetes. Different drug combinations can be seriously harmful or even fatal and Nicholas Tatonetti and Russ Altman from Stanford University went to Adverse Event Reporting System(AERS) database to find such combinations. The researchers look for drugs that caused blood sugar to rise, which is a symptom linked to diabetes, but they found nothing. Then they looked for combos that were involved in diabetes, and searched the AERS for side effects linked to these drugs. One combination was bold: paroxetine(antidepressant) and pravastatin(used to lower blood cholesterol). They then got together with researchers from Harvard and Vanderbilt to study medical records of people given these drugs together. The records showed that patients given both had a rise in blood sugar, especially people who were already diabetic.
I think that this finding is huge! I also think that researchers should absolutely look more into this and reveal which drugs can cause more harm than good. If a combination can cause diabetes than they could cause worse things like stroke or heart attack and lead to more serious cases. The point of drugs is to help patients recover and get better, not give them diabetes and heart attacks. So, in my opinion this needs to be researched heavily and prevented.
Elephants
Summary: In the last five years 2000 elephants have been killed near Chad's Zakouma National Park. Hunters desperate for the elephants ivory tusks; have killed several park rangers. There has recently been an act to save the elephants; or protect the rest in existance. Their rank on the endangered species list is getting dangerously close to the end. Park rangers are doing the best they can to protect the rest of them. The US is helping fund the rescue missions. 18 million dollars to be exact.
Opinion: I agree that the elephants need to be protected; but the US can't exactly afford to help out with that right now. The government needs to start being smarter with money. I mean, I could understand some helping, but 18 MILLION dollars? Really America. I will admit it is rather strange that hunters are so desperate for the elephants ivory tusks, that they are killing park rangers. But this is crazy!
Bacteria Use Caffeine as Food Source
http://www.biologynews.net/archives/2011/05/24/bacteria_use_caffeine_as_food_source.html
A new bacteria, found by a doctoral student at the University of Iowa, has been discovered that uses caffeine as a food source. This bacteria, Pseudomonas putida, uses new digestive enzymes to degrade the caffeine and uses the nutrients to live and grow. This bacteria breaks down the caffeine in to carbon dioxide and ammonia. Caffeine is made up of carbon, nitrogen, hydrogen, and oxygen, which the bacteria needs in order to grow. The caffeine molecule contains three structures, called methyl groups, which are made up of 1 carbon atom and 3 hydrogen atoms. Bacteria can remove these methyl groups and can technically just live on caffeine.
I believe this new discovery is unique, great, and weird all at the same time. I like how no one else has been able to discover this, even though we have had to technology to do it for a while. I think it's great now that we have the knowledge of another way bacteria can grow and live. I believe this discovery is weird because I never thought that bacteria could just live off of caffeine. I thought they had to live off of food and water like us. I am very shocked by this discovery, but I think it is one that will benefit us in the future.

Marine Carbon Cycle: Fish
Using Micrboes to make electrcity.
This new information is really amazing. Bacteria that can generate electricity? So many things can happen with ability. It could change how the whole world works and how it gets its energy. The scientist only found some info on maybe how this is possible, but I believe it can be done.
http://www.sciencedaily.com/releases/2011/05/110523152337.htm
Using Microbes to Generate Electricity?
This means that scientist can now start creating microbial fuel cells, or "bio-batteries". Scientist can also start making microbial agent that could help clean-up oil and uranium pollution.
This is a really big breakthrough that these scientist have made. We know that bacteria are organisms that can reproduce very fast, some at a rate of about every 20 minutes! Imagine what could be done with this discovery... making natural and clean energy that could also be applied to clean the waste out of our environment. We have been trying to find clean energy like this for years, and hopefully, now that the doors are open to it, people will be able to find other applications to it. They have now found a new energy source that can benefit us in many ways.

Nanopatch Created for Heart
This technology is very interesting to me. My ideal career is an interventional cardiologist, and therefore this might be a technology that I will use routinely in the future. It is exciting to know that hearts damaged from a heart attack can be fixed almost as easily as putting a band-aid on. This will make the threat of secondary heart attacks less severe (as long as the patients stay away from double cheeseburgers), and allow patients to recovery quicker. I'm looking forward to seeing these in widespread distribution.

The Immune System Of The Microscopic
This article was about the new research that has been studying the immune system of bacteria. As you may have heard some strains of bacteria are becoming resistant to certain antibiotics. Well researchers have been studying how bacteria fights off viruses and these antibiotics. The CRISPR is the immune system of bacteria. They believe that the answer may lie in the way RNA splits up. They haven't come up with an exact answer yet but they are getting closer every day.
This is amazing. One of my favorite bacterias to study is NF (Necrotizing Fasciitis) which is the flesh eating virus. It's fatal because it's resistant to all antibiotics. If this research continues then it might be possible to find a way to stop it, along with other resistant bacteria. Being that this is a large concern to public health I strongly hope that they find the answer. This could be a huge step in controlling the future outbreaks.

Snakes!
Summary: The titanaboa is the largest snake currently recorded. Now extinct, it is believed that the snake lived in the neotropical forest over 58 million years ago. This large creature was 42 feet long, and 251O pounds! Recently scientists have "unearthed" the first evidence of this creature living in the neotropical forest! This creature became extinct during a mass extinction. The forest currently contains hardly any plants, which makes scientists wonder if thats why the mass extinction occured.
Opinion: I think it is really cool that scientists can trace life back so far. Technology has really come a long way. Just by todays discoveries they can tell why a mass extinction occured! I wish I could do that. The creature seems massive, and I kinda wonder how it was found in the first place, and why the discoverer, didnt run away.

Genome of Marine Organism Reveals Hidden Secrets
A Seal’s Hard-Working Whiskers.
Male Infertility
Alien Life.
Summary: Scientists from multiple colleges (Princeton University; the Kennedy Space Center; and Michigan State University) have been studying whether or not terrestrial bacteria would be able to survive on Mars. They have taken bacteria from Siberian Permafrost, from Earth, and isolated it under harsh conditions; similar to those on Mars. After the experiment, scientists came to the conclusion that the bacteria could not survive on Mars. Scientists still believe under the surface there may be a possibility that aliens still can exist.
Opinion: Why is anyone so stuck on proving that aliens exist. I think is really stupid that they keep trying to prove something that they have not been able to prove yet. It has been a long time. When are they looking to give up? I really do not think that putting bacteria from Earth under similar conditions to those on Mars will prove anything.
Flat worm Regeneration
Scientists found out this unique cells that is able to regenerate the whole body. With this information, we might be able to implant this or something like this to humans giving the ability to regenerate. This is still very new and unkown, but this knowledge is one step closer to regeneration. If we Are able to use this knowledge to help humans, it will change the world. Of course, this should be researched a lot more before doing anything big.

I find this quite interesting. I did not know that they had a yolk sac that kept them fed for 2 weeks. I guess natural selection is hard at work here! I really hope more than 30 % will make it after the scientists moved the eggs towards the shoreline. I think this will do wonders for the turtle community (not endanger of becoming extinct).
Genome of Marine Organisms Reveals Hidden Secrets
http://www.biologynews.net/archives/2011/05/10/genome_of_marine_organism_reveals_hidden_secrets.html
A genome of marine organisms has been found to produce substances that can be possibly be useful against human diseases. Cyanobacteria, small photosynthetic microorganisms, are potentially the oldest forms of life on Earth. The Cyanobacteria blooms can cause a threat to humans and animals, but the L. majuscula cyanobacteria has been used to create hundreds of natural medicines. Little is known about the genetics behind the bacteria. The Cyanobacteria play a major role in the global carbon cycle. Cyanobacteria are going to be used to help create medicines to benefit humans on Earth.
I believe the discovery of this genome is one that will benefit us more than the genome. If the Cyanbacteria continues to create natural medicines, we won't have to rely as much on us; we will rely more on nature. Since the Cyanobacteria are potentially the oldest forms of life on Earth, it makes me wonder; why haven't we discovered this great genome earlier in life to help create natural medicines? I believe scientists should have investigated and observed this marine genome a long time ago so we could have this knowledge earlier. The Cyanobacteria will hopefully continue to create natural medicines that will benefit us humans more in the future than in the present.

Marine Carbon Cycle: Fish Are Major Players
Vicious Dolphin like thingy in cold
Air Pollution
Summary: Air pollution is getting out of hand. Especially in eastern countries. The pollution is getting so bad, it is starting to be the blame for the multiple deaths that have occured there recently. Air pollution is mostly being blamed because it has been discovered that small particles get past the bodily defenses and into the lungs.
Opinion: This is really dangerous. I am worried that the pollution will get worse just in the next few years, based on how bad it is now. The death rate will increase and the life span for humans will decrease due to the premature deaths.

Newly Discovered Plant Fossil Reveals More Than Age
Decoding Cancer
For a long time doctors have always known that cancer destroys and changes cells. It's not until now though that they have realized what exactly they do to them. Research has shown that it damages the cells by taking away their ability to form and takes away their "building blocks" as they put it. They are hoping to (with this new information) that they will be able to go in and replace these lost "building blocks" stopping the cancer from being able to destroy the cells.
Out of all the current events I've done, none excite me as much as this one. This could be the CURE for cancer here! If we're able to do this, and I hope that they keep researching it could mean being able to stop cancer before it destroys their lives. It's a far shot, but if we can grow human organs in pigs, then why not be able to do this. Cancer is a horrible and painful thing, being able to stop people from having to experience this would be a wonderful thing. I personally don't know anyone with cancer, but some of my friends do, I think this is far more important then trying to genetically engineered babies for the rich. This could actually save already existing lives! And many more to come.

Endogenous Proteins Found in a 70-Million-Year-Old Giant Marine Lizard
I think discovering new things are amazing. New things are always being found and many of them help human kind. I'm not sure on how exactly this can help, but having knowledge of this could be usefull. I also think it is intersting that they used so many differnet ways to find that protein. For example they used some kind of radiation based infrared microspectrosocopy at MAX- lab in Lund, Sweden.

Tropical Blueberries http://www.biologynews.net/archives/2011/04/27/tropical_blueberries_are_extreme_super_fruits.html
Blueberries that grow in Southern countries, such as Mexico, and Central/ South America have been found to have more antioxidants than regular blueberries. They are now known as super fruits. Antioxidants are used to gather up free radicals in your body. These fruits are also known as neotropics. Neotropic is an area reaching from the Tropic of Cancer to South America and towards the West Indies.
I wonder why these super fruits are so super. I would like to know what causes them to grow so well. I think that this is wonderful, it can save people from cancers and other diseases. Maybe we can genetically engineer other fruits to have these amazing antioxidants. We could modify them to grow in colder areas. This could help those in colder regions (up north) farm and have fresh fruits during the winter.

Tree Growth Stunted By Ozone
The concern that a large amount of trees are being cut down is being discussed . As I recently learned that is not the only problem we have with trees and the amount of oxygen produce . The recently measured the tree growth and learned that it is seven percent shorter today than it was in the 1800's . The reason for this is the amount of ozone pollution in the atmosphere . As the amount of pollution increases the height of trees decreases .
