According to this article, Research from North Carolina State University offers a new technique for determining the sex of skeletal human remains. It is said to be significantly more accurate than visually evaluating the size and shape of the pelvis because when you are faced with fragmentary remains of the pelvis, it can be difficult to determine the dead person’s sex just by visual inspection. Now, Ross and Bytheway have used “a three-dimensional imaging technology to effectively quantify the specific characteristics of the os coxa that differentiate males from females.” Researchers discovered more than 20 anatomical “landmarks” on the pelvis that can be used for determining the sex. This is important because it means that you can determine the sex of the body even with a small fragment of the pelvis. At least a few of the landmarks should be found on the fragment. Now a forensic scientist can use a digitizer to create a three-dimension map of the pelvic fragment and measure the relevant anatomical landmarks, then compare these measurements to the measurements discovered by Ross and Bytheway.
This article relates to science/biology concepts since determining the sex of skeletal remains has to do with the pelvis in the human body. It tells us how the process works, by creating a 3D map of the small pelvis fragment then comparing the measurements to the measurements discovered by Ross and Bytheway. It also tells us why this way is more accurate than just visually evaluating it. This article basically has to do with the fragments of the pelvis from disasters such as plane crashes or “degraded remains in mass burials.”
This information was put in the newspaper because we are concerned about how they would determine the sex of skeletal remains by the fragments of the pelvis. Like they said, it is difficult to determine the sex just by evaluating the size and shape of the pelvis, and it is not as accurate, only 90%. This new technique is said to be at least 98% accurate, and it can be useful to many of the archeologists who are interested in determining the sex of the skeletal remains that they have found.

Human Noise Pollution in Ocean Can Lead Fish Away from Good Habitats and Off to Their Death
http://www.sciencedaily.com/releases/2010/08/100803212015.htm
According to this article, “ the growing amount of human noise pollution in the ocean could lead fish away from good habitat and off to their death.” It says that starting from the time the fish are born and after weeks of developing in the sea, the baby reef fish rely on natural noises made by fish, shrimps, and sea urchins as a cue to find the coral reefs. This is where they can survive and be able to grow well. With the human noise pollution, it makes the fish become attracted to inappropriate noises with “small boats, shipping, drilling, pile driving, and seismic testing” which sometimes drown out the natural noises of the fish, shrimps, and sea urchins. Researchers are now worried that this crucial behavior is causing harm and possibly high death rates for the baby reef fish if they get attracted towards the wrong sounds, which can lead them into danger. The researchers also tried an experiment which shows that the baby reef fish can learn a new sound and remember it within a few hours. The human noise pollution can really mess up their recognition on natural noises on the most important night of their lives. After that night, it will be able to know what sound it is suppose to follow and if it’s the wrong sound, which they wouldn’t know, then it’s off to their death since “they could end up stuck next to a construction site or follow a ship back out to sea.” Over the years, these noisy environments have increased drastically, which “could have devastating impacts on success of populations and the replenishment of future fish stocks.”
This article relates to science/biology concepts since it talks about how the baby reef fish in the sea are getting affected by the human noise pollution. It tells us how it can lead to their death if they recognize the human noise pollution instead of the natural noises from fish, shrimps, and sea urchin. If only the human noise pollution can be reduce as time goes on, then it wouldn’t be such a big problem to the population of baby reef fish. Since over the years, these noisy environments have increased dramatically, it means that their death rates are increasing as well.
This information was put in the newspaper because we care about the survival of the baby reef fish. We are the one who are causing this devastating affect on them. Since they are baby fish, they can’t tell between the right and wrong sounds. With our human noise pollution going on, it’s making it harder for them to distinguish. We feel horrible about this situation, but hopefully the human noise pollution can be reduced.

Bats Facing Regional Extinction in Northeastern US from Rapidly Spreading White-Nose Syndrome
http://www.sciencedaily.com/releases/2010/08/100805142945.htm
According to this article, a new infectious disease known as white-nose syndrome has rapidly been spreading across the northeastern US. This disease has killed millions of bats, and researchers predict that it may cause a regional extinction of the bat species that was once so common. This disease was first discovered in 2006. Now it is spreading quickly and is affecting 7 bat species. It is one of the most common species in North America, and if the disease continues to spread and death rates are high as they have been over the past 4 years, a regional extinction will most likely occur. Researchers have said that “bats perform valuable ecosystem services that matter for both the environments they live in and have tangible benefits to humans as well.” These bats have been insect-eating species, and they can “consume their body weight in insects every night including some consumption of pest insects.” These bats matter for insect control or else our environment will be full of insects that may be harmful to us but not to the bats. Later on, they found out that this disease is associated white fungus that grows on the bats’ noses, ears, and arms. It disrupts the bats’ hibernation, causing them to awaken early and lose fat reserves, which leads to early death. The researchers are 99% sure of the regional extinction if this continues to happen within the next 16 years. They also said it is possible that this deadly fungus came from Europe through human trade or travel. The same fungus has been found on the hibernating bat species in Europe.
This article relates to science/biology concepts since it’s talking about how this white-nose syndrome disease affects the bat species and will cause them to regional extinction. It shows that researchers need to find a solution as soon as possible before the bats really go into extinction. Not only is the disease causing high death rates for the bates, it will also affect us in the future. They are insect controllers to us, meaning we depend on them in a way, so that our environment won’t be filled with harmful insects.
This information was put in the newspaper because we care about the extinction of the bat species that was once so common and healthy. It was also a population of an abundant and widely distributed species. Also, without them, we could be having trouble in the future with the insects, and many of them may be harmful to us. Yet, it is so sad to see that they are about to face regional extinction by this newly infectious disease. Researchers aren’t even positively sure that the white fungus came from Europe, but they are working on it, so hopefully they can find a solution to this disaster. This is affecting the bat species, but could be affecting us in the future too; we wouldn’t no until it happens.

The Healing Effects of Forests
http://www.sciencedaily.com/releases/2010/07/100723161221.htm
According to this article, “ Many people feel relaxed and good when they are out in nature. But not many of us know that there is also scientific evidence about the healing effects of nature.” It says that the forest and other natural green environments are a great place to relax during the times when you are stressed out, in a horrible mood, angry, depressed, etc. It can help u release stress, improve your mood, reduce your anger, and basically brings up your mood to a happier level. It also says that many people recover faster and feel better in natural environments rather than urban environments because it helps decrease your blood pressure, heart rate, muscle tensions, and the level of “stress hormones” faster. Playing in natural green environments also help children decrease their hyperactivity disorder. One of the important facts is that these green settings help improve people’s working ability and reduces health care costs. It is important to keep these green settings because it can help cure diseases, and maintain health and mental stability. It says that more than half of the most commonly prescribed drugs in medicine came from nature, and examples of that are Taxol and Xylitol. This article is basically telling the reader why it’s important to preserve green settings.
This article relates to science/biology concepts since it shows how natural green environments can actually help improve our health, such as reducing blood pressure, heart rate, and muscle tensions faster. It also helps you maintain a stable mind, causing you to release stress. This is important because when you are very stressed out, it may cause symptoms such as raised blood pressure or depression. Being in a natural green environment not only improves your health, but also increase your overall happiness. These environments are making a difference since it will improve your health, it also means a lesser chance of getting diseases. Green settings are basically a benefit for the human body.
This information was put in the newspaper because we care about our health. All of us want to live a long life, so in order to do that, we need to keep a healthy body. Getting stress all the time and keeping it all in over such things as homework, work, and relationships aren’t a healthy thing to do. It can ruin your health and easier for you to get cancer or diseases.
