Branches of science

There are many branches of science which concentrate themselves on the many areas of discovery. The majority of sciences end in -ology which is a suffix meaning “the study of”.

The larger fields of science can be broken down into smaller and smaller areas of study.

Despite the many branches of science, they all gather information in similar ways. The scientific method is a way to organize and standardize the method of data gathering during experiments. This makes it easier to replicate experiments which adds credence to the initial results.

The New LEDs Technology That Uses Low Power Input To Produce More

LEDNew development in illumination uses small and resourceful technology of light emitting diodes popular known as LEDs. The technology uses low power to produce the best results that can be seen even on the screen of mobile phones. The increase in amount of power that can light a room just like the traditional light bulb decreases their working efficiency. This is known as the LED flops and is a huge lug in this technology. However, the manufactures have developed efficient LEDs which give good results even as they input lower power currents in the most sophisticated areas of the green and bluish parts of the spectrums.

LEDs are made of semiconductor layers arranged between metallic electrodes similar to an ordinary sandwich. When the power is directed on the electrodes, electrons charged negatively and holes charged positively are pressed in the center of the layers. This causes reactions that result in production of light.

This sounds simple but there is a setback. The semiconductors sheets in blue and green LED placed at the middle are made of gallium nitride.

A Breath of Fresh Air

ratScientific breakthroughs are occuring at an unprecedented rate in the modern world and it would seem that the latest patients to benefit are a group of rats in Connecticut. Following the removal of the rats’ left lungs, Yale University scientists were able to replace them with lab-grown lungs. While the rats in question did not survive beyond a couple of hours following the procedure, researchers were still able to ascertain that a fully functional lung could indeed be created and transplanted successfully into a living organism, a finding that undoubtedly has far-reaching implications for further research.

In a related case of lab-grown organ research, a separate group of rats at the Massachusetts General Hospital received artificially created livers which allowed them to live for nearly ten hours, up until the transplanted organs were removed. This serves as yet another example of the progress being made in the area of organ growth, an area that is set to one day revolutionize the calibre of medical care provided to human patients and eliminate the need for lengthy transplant waiting lists.

How to eliminate harmful bacteria

bacteriaBacteria are one of the hardest elements to eliminate. But recently researchers have developed an easier option to eliminate bacteria through a remote technological disinfection by use of movable flashlight that produces rays of cold plasmas to eliminate bacteria within a shorter time. Experts in the medical field have hopes on the plasma technology. Plasma gases are produced in electrical discharges, with no electrons and ions have been tested to produce harmful effects on the pathogens.

In addition they are good in wound healing and cancer treatments. Researchers have not concluded how this works, but they know it is through reactions of oxygen found in air. The molecules that are reactive, and also found in our immunity, work by oxidizing cell membranes, therefore destroying DNA systems. Equipments using the plasma technology are few and in testing phase to ascertain if they can work well. The machine must produce own power internally needed to release electrical discharges. An externally generated gas might also be required to power and maintain them. With all the above consideration, it becomes difficult for them to be used in time of emergencies, disasters responses and in military.

The Debates on whether Light Bends

bending lightBasic physics or laws of physics argue that the main principle of light travel is on a straight line. Recent discoveries do suggest that light can bend or travel in curves independently. Otherwise, it is clear that light has its own laws of travel and at times without these laws of physics some of the recent discoveries would still be major scientific milestones. On the other hand, even though there are still truths that these effects are normally as a result of optical illusion there is still evidence that light bends without external influence from particular observations and scientific deductions after specific experiments.

The whole idea of optical illusion emerges from various optical properties which include gravity\’s nature of warping and refractive index. The refractive index is whereby light seems to take a significant turn through water resulting to tilting effects when an object is immersed in water. For instance, if you were to place a pen in water or a straight rod you will notice that pen or rod appears curved while under water. For gravity\’s warping nature anyone who observes the movement of stars will notice that they seem to travel in a curved direction or any of other heavenly objects such as meteors or asteroids. Therefore, all these observations can be attributed to optical illusion where the curve aspect on light travel is influenced externally either though water or gravity.

Understanding of anti aging pill on DNA

pillsThere has been a lot of interest on research for understanding the process of aging in relation to the telomere component of DNA. This part of DNA is characterized by a repeating sequence which shortens at the end of a chromosome during cell division. Persistent shortening of the telomere leads to eventual death of the cell and this is what has triggered research studies on how find pill, DNA product to arrest the situation. Several groups of researchers have since claimed that a solution for slowing down the winding process as a result of enzyme activity is possible. These independent groups are said to have come up with this remedy for manipulating the telomere in form of pills.

Telomerase enzyme plays a key role for the maintenance of telomere in reproductive and stem cell activities in the human body. Research studies carried out by biotechnology giant firm, Geron Corporation in the year 2001, was able to reveal the possibility of isolating a molecule called TA-65 from astragalus plant. According to this team of researchers, the molecule was able to boost activity of telomerase enzyme within the body. This theory has however not been published among the evaluated peer-reviewed studies.

Earth’s mantle containing electrical material is a prime cause in the variation of Earth’s Rotation

earthIt is not always true that geophysicists have all the answers regards to the deep secret of the Earth’s rotation. There are different variations based on which these scientists are working hard to figure out the exact theory of the rotation of planet Earth. Latest discoveries are saying that Earth’s mantle, which is a substance of hot softened rock, is one of the prerogative reasons behind the Earth’s rotation. Geophysicists have clarified that through novel researches it has been proved that Earth’s mantle is all set with the quality of conducting electricity. It is iron monoxide that is responsible to conduct electricity just like any metal within the mantle. Total 9% of the Earth’s mantle consists of this iron monoxide.

Recent researches and discoveries have suggested that there are slight variations in the math that is generally ordained as the time period of an Earth’s Rotation. This is somewhat increases the timing of the Earth’s spinning in the annual course and months. This is a geographical fact that the earth rotates on its axis but constant researches have also challenged this theory and prescribed leaning and swinging of the planet while rotating.Geophysicists are suggesting that this kind of variation in swaying and swinging in Earth’s rotation is possible as the thick and concrete iron inner core, liquid metal outer core and rocky mantle are all not rotating at a fixed time. According the earth scientist Bruce Buffet of University of California, with the friction, these layers of earth’s core can be drawn under a line but to make the whole thing work out, the core will have to apply magnetic pull on the mantle.

How Mouse Memories Are Created

mouseOne of the most important studies that scientists have done about cognitive processes is about memory. Years ago, the movie “Eternal Sunshine of the Spotless Mind” depicted how scientists deleted disturbing memories that bothered the main character portrayed by Jim Carrey. Today, such experiment was done with reverse results. Of course, the study was conducted among animal subjects like mice.

The results of the studies were published last March 23 (Science) and March 22 (Nature-online version). But instead of removing memories as shown in the movie, scientists were able to create artificial memories into the mice’s brain. Indeed, this is interesting because the study profoundly reveals how the brain generates and utilizes memories.

Generally, scientists learn about brains functions (like memory) from similar studies that seek for signs of natural memories. Studies about things that intervene with memory or recall also provides information to researchers. However, in the new study, memories are created according to Richard Morris, a neuroscientist form the University of Edinburgh in Scotland. Dr.Morris believes that the new study is a breakthrough that would provide significant advancement towards understanding memories.

How Global Warming and Disappearing Sea Ice Increasing the Amount of Snow

global warming The problem of global warming is not unknown anymore. Global warming is responsible for bringing unnatural changes in the worldwide weather. This problem has accelerated the severity and length of winter in Northern Hemisphere. A new study claimed that the melting ice of arctic sea sends cold air toward the equator and creates the stage of snow.

Scientists from different parts of the world are studying the possible consequences of this problem and creating awareness. Jiping Liu, a renowned climate scientist of Georgia Institute of Technology in Atlanta explained that if the sea ice continues to reduce dramatically, it will ultimately increase the amount of snow. He was also the co-author of the study published online in Proceedings of the National Academy of Science on February 27.

It is strange that despite rising temperatures, different places on earth endured abnormal snowfall and harsh winter. According to the records, few of the noticeable incidents are abnormal snowstorms in the east coast of United States during the winter of 2009-2010 and 2010-2011, exceptionally high level of snow recorded by Japan this winter and the canals of Danube and Venice in Europe projected a rare view when the water froze over.

Reduce the Excess Greenhouse Effect to Avoid Dangerous Global Warming

global warmingGlobal warming causes climate change can be felt by all human beings on earth. It happened because of an imbalance of Earth’s ecosystems and the increasing emissions of greenhouse gases excessive to make the average temperature of the earth’s surface is higher. Emissions of harmful greenhouse gases include carbon dioxide, dinitrogen oksida, methane, sulfur hexafluoride in the atmosphere. A new study suggests that we should reduce the harmful gas to keep the temperature in the atmosphere becomes more stable. Something that we must do is to reduce emissions of greenhouse effect that produces a number of excess heat from the normal operating condition, although needs a technology with a more expensive cost.

Did Tropical Oceans take away East Africa’s woodland biodiversity?

desertWhat happens in the sea affects land. According to the American Association for the Advancement of Science, huge temperature variations in the Indian and Pacific Oceans, two million years ago, changed East Africa’s rain cycle leading to a dry weather that has wiped out woodlands and replaced them with grasslands. Many valuable plant and animal species have perished as a result of the weather change.

Peter deMenocol who is a marine geochemist and geologist at Columbia University notes that a number of theories have been floated to explain the climate change. Volcanic activities, cooling of North Atlantic Ocean, greenhouse gases concentration and the diminishing atmospheric pressure being some of the projected scientific opinions.
