Science News

The latest current science news is that having walnuts as a major component of the diet can be highly beneficial to males. The science news circuit has stated that in an experiment involving mice, those mice that primarily had a diet that was high in walnuts developed prostate tumors slower than those that did not. The science news circuit has stated that this experiment was carried out under the direction of Paul Davis, who works at the University of California. The study was conducted by observing the diets of mice that were known to genetically develop prostate cancer. The science news circuit says that the normal diet for mice is consumed of 5 percent of calories of fat a day. In order to see what effects walnuts had on the prostate tumor, the researchers increased the diet to 20 percent of calories of fat from walnuts each day. Other mice that were prone to these prostate genetic tumors had a diet increase of 20 percent of fat from other fats. In the current science news reports, the mice that had the increase of walnuts had prostate tumors that developed slower than that of the others.

Although not an exact component for the basis of this particular study in recent science news, walnuts have been shown to be proven in previous science news stories. These science news stories featured the way that walnuts may serve as beneficial to the heart. This is because studies have shown that walnuts can fight inflammation, which allows the blood vessels to dilate. Due to the fact that inflammation often plays a role in any type of cancer, including prostate cancer, this latest current science news story has shown that there can potentially be a double benefit of the consumption of walnuts to those that have cancer.

The current science news story that has been getting much talk lately involves one of the issues that has seemed to appear within science news time and time again. This time, there is a new twist on this current science news story. This is the science news story that involves obesity. Usually, there is an active push in current science news to offer solutions to those that are in the younger age brackets with ways in which they can tackle obesity, but this science news story is a bit different. It encourages those that fall within the older age brackets to take on these efforts to loose weight. The current science news is that those that initiate weight loss at an older age may very well reap the health benefits. This is such a twist to current science news because it has been one of the strong beliefs of many within the scientific community for quite some time now that those that choose to loose weight at an old age is carrying out an act that is unhealthy to their body. The study was conducted with those that were obese, within the 70 year old age range, and who had arthritic knees. The science news states that this was a study that was studied over a long course of time. The elements of study were putting the patients on a special diet, using a combination of diet plus exercise, exercise only, and health education only. The current science news is that the study showed that those that only 15 people had died that were on a weight loss program, in comparison to the thirty that were not. Although this is not the end all, be all, study conclusion on the elderly and weight loss, it has started some rather intense discussions on the matter within the science community.

Science Projects

Whether you would like to carry out a science project on your leisure time, or there is an important science fair that you are preparing for, many enjoy conducting science projects. Carrying out these science projects is a way in which one may discover new things, while having a fun time in its execution. One of the science projects that can be used to accomplish either one of those goals is a science project that is conducted in order to study the effect that temperature has on a chemical reaction. There are three materials that you are going to need in order to carry out this science project. To most accurately carry out this science project, you are going to need a glass, water, a thermometer, and three Alka-Selter® tablets. The science project begins with filling a glass with cold water. From there, you are going to measure the temperature of the water that you have placed in the glass. This temperature is to be recorded on a piece of paper or a chart, whichever you choose. The next step is to drop an Alka-Selter® tablet into the water. Observe what rate the chemical reaction occurs at this temperature, as the tablet dissolves in the water. Then you are going to take note on your paper or chart of how fast or slow the chemical reaction occurred. From there, you are going to repeat this process for the remainder of the science project for a warm temperature, and a hot temperature. At the end of the science project, your observations recorded on the chart will allow you to conclude when it is that a carbon dioxide chemical reaction occurs faster, whether it is with a colder or a hotter temperature liquid.

The next of the science projects is one of the signature science fair projects. This is because it is yet another one of the science projects that has to deal with ice. Nevertheless, this is not necessarily the same as any of the other ice science projects because it is a different conclusion for which is attempted to be reach. That is, this is a science project that is conducted in order to determine what material that is added to ice will allow it to melt the fastest. Although this is one of those science projects that requires several materials in order to reach a conclusion, this is also one of those science projects to which you are able to find most of the materials that you need in your home. In order to begin this science project, you are going to need a bowl, four cubes of ice, salt, sugar, sand, pepper, and a timer. The only material that you may not have in your home in order to begin this science project is sand. However, if you do not have sand, you are still able to carry out this science project. The first thing that you are going to want to do is to put a cub of ice into a bowl. The next step is to sprinkle a tablespoon of salt over the cube of ice. From there, you are going to observe how fast the ice melts. From there, you are going to start your timer. Once the ice fully dissolves, you are going to stop the timer and record how long it takes for the ice to dissolve using salt. You are going to repeat this process for the pepper, sugar, and sand. This is one of the science projects that has a clear conclusion. By the end, you are going to be able to conclude what substance melts the ice fastest.

Science Fair Projects

One of the science fair projects that one might want to try out is one of those science fair projects that may be conducted from the comfort of your home. This is also one of the science fair projects to which you are bound to have all the necessary tools and instruments that you need to conduct the science fair project at your home already. In fact, this is a science fair project that is specifically performed on the leisure time of many because it is a topic of interest, and the fact that this is a science fair project that does not require that you have an abundance of materials. This science fair project is the one in which you measure the diameter of the sun and the moon. The first thing that you want to do is draw a sun and a moon on a large piece of construction paper, taking up 1/2 to 2/3 of the paper. The next step to this science fair project is to color the sun and the moon the appropriate colors. From there, you are going to use a ruler to measure the middle of the circle. You will then use the following formula in order to reach your conclusion:

diameter of the sun = diameter of image of the sun
distance from sun to earth distance from pinhole to image

The second science fair project is also a science fair project that you will be able to conduct from the comfort of your own home. The second of the science fair projects is investigating what the point of boiling water is. In fact, this is one of the science fair projects that is most commonly conducted. But there is always an element of uniqueness about science fair projects that come to withstand the test of time. And for this particular science fair project, it is the fact that there is always something to be learned. This is because science fair projects such as this comes with that personal element of discovery. However, this is one of the science fair projects that is recommended to be carried out in the presence of an adult. Those science fair projects that call for the usage of the stove usually warrants such supervision. Especially because this is one of the science fair projects that calls for you to go about testing boiling water. To begin this science fair project, the first thing that you are going to do is fill a pot half way with water. Then you are going to sprinkle a table spoon of sugar in the pot of water. Use a thermometer to measure the current temperature of the water. Then, under the supervision of an adult, if applicable, you are to bring the range to a medium temperature. When the water comes to a boil, use the thermometer, once again to measure the temperature. At the conclusion, you are able to detect the temperature of a liquid when it comes to a boil.

Science News

One of the science news stories that many are talking about is the latest story that has been released which states that multi-celled animals may potentially have the capacity to live without the supply of oxygen. The initial idea that had been floating around the science community was that only single celled species had this capacity, but this may not be the only exception to the rule. Marine biologists have the science community bubbling with their latest discussion. Although the marine biologists stand by the fact that they have not released any concrete evidence in order to allow them to stand by this theory, they are in deep and open discussion about such a theory. One of the creatures that has been most recently stated to have this capacity is called a loriciferan. A loriciferan is less than a millimeter long, have limited mobility, and can be found in the coarse-sand and shell-hash habitat. It is a creature that can typically be seen in the Mediterranean Sea of North and South Carolina. This is in the general area where marine biologists were able to find the species of loiciferan 3.5 kilometers below the surface of the Mediterranean Sea. The recent science studies that have been conducted have led many to believe that the loriciferans are able to survive without oxygen because there has been cast-off skin found, which implies that the loriciferans are growing. This allows biologists to further conclude that there is a possibility that these loriciferans may be reproducing there, as well. This recent discussion seems to be only the beginning phases of what is slated to come as marine biologists further delve into this idea of the existence of multi-celled, oxygen free, creatures.

Another story that is current to science news is the debut of the element that physicists have proclaimed has been added to the periodic table. This synthesizing element is a super heavy element and is numbered 117. Element 117 was created in the laboratory of the Joint Institute for Nuclear Research in Dubna, Russia, under the leadership of Yuri Oganessian. Other collaborators of this effort was Vanderbuilt University and Oak Ridge National Laboratory of Tennessee of the United States. Element 117 is presently being referred to as ununseptium, but has yet to receive a permanent name. The element is made up of calcium-48 and berkelium-249. The formulation of this new element has helped researchers already in the capacity of understanding the super heavy elements such as this. Researchers have taken a particular interest in the way in which the two element 117 isotopes decay, causing there to be new products that are formed as a result. The isotope decays to dubnium, in an isotope with 177 neutrons and roentgenium in an isotope with 176 neutrons.

One of the latest science news stories is one that seems to be reoccurring. Coming up on the ten year marker since the 9-11 attacks at the World Trade Center, rescue workers still have related complications. The New England Journal of Medicine has just issued a report, this month of April 2010, which states that rescue workers continue to show breathing difficulties. One of the most recent, most noted tests, to have been conducted was performed by a pulmonologist by the name of Thomas Aldrich. Thomas Aldridge practices at the Montefiore Medical Center as well as Albert Einstein College of Yeshiva University in New York City. The study was conducted by testing the lung function of 10,870 firefighters and 1,911 emergency medical service workers. The data was taken from a year before the 9-11 exposure, and through at least 3 follow-up tests that were conducted up until the conclusion of the year 2008. The science circuit has stated that the initial reaction was that the initial cough that was received as a result of the exposure to the scene, would go away like the common cold, but that has not been proven to be the case in some instances. It is said that the exposure to the dust, cement, and glass fibers, that were witnessed has subjected some to the development of bronchitis and asthma. Some have also been noted to suffer from various different pulmonary diseases, as well. Those rescue workers that were exposed to the dust the soonest after the attack, were said to be more prone to have a related lung condition as a result. Some environmental scientists say that part of the cause why such medical conditions have presented themselves could very well be due to the fact that may of the rescue workers witnessed exposure to these harmful elements without the proper protective supplies being offered, especially for those that worked within those first few days to weeks on the scene.

Our final science news story comes with a seasonal, yet scientific twist. It is the recent scientific discovery of the zebra finch songbird. The zebra finch songbird has just become the first songbird to ever have its genetic pattern revealed. One of the aspects that has been of particular interest in discovering the genetic background of a zebra finch is in relation to how it uses its gift of song. This discovery is being used to how zebra finches learn how to sing, and exactly when and where the zebra finch is inclined to sing. In relation to the way in which the zebra finch learns its song, it is said that the male zebra finches learn from their fathers. They then go on to practice the song for about a month to two months. It is after this point that the zebra finch begins to take on that particular song in its greatest form. A zebra finch will then come to sing this signature song the rest of his life. Ultimately, this is a study that will not only help scientists to be better understand the lives of zebra finches, but studying how zebra finches sing is an aspect of the study that can be attributed to further help with the understanding of autism, stuttering, as well as other communication disorders.
