What is Science?

2011-06-14T21:35:00.002+05:30

The word science comes from the Latin word "scientia," meaning knowledge. Particularly it refers to experimental sciences. According to Aristotle,"scientific knowledge was a body of reliable knowledge that can be logically and rationally explained. Science is the systematic study of nature and how it affects us. In modern use, science is often treated as synonymous with ‘natural and physical science’, and thus restricted to those branches of study that relate to the phenomena of the material universe and their laws, sometimes with implied exclusion of pure mathematics.

Hard Drive Data Recovery

2009-06-04T13:08:00.002+05:30

If your hard drive had been formatted and you lost all the important files, datas and anyother important documents, then it's no need to worry. Advancement of technology has solved your problem. It has developed softwares that recover your lsot data. Now you can enjoy your days with family enjoying the lost reminiscences of your digital cameras because they will be again in your own pc as it used to be before. Your boss cannot scold you no longer because the needed lost files can be found immediately. Data recovery is the process of salvaging data from damaged, failed, corrupted, or inaccessible secondary storage media when it cannot be accessed normally. Often the data are being salvaged from storage media formats such as hard disk drives, storage tapes, CDs, DVDs, RAID, and other electronics. Recovery may be required due to physical damage to the storage device or logical damage to the file system that prevents it from being mounted by the host operating system.

Swine Flu Now Reported in All 50 States in US

2009-06-02T21:17:00.000+05:30

June 1 (HealthDay News) -- Swine flu cases have now been reported in all 50 states, with the total number of people infected probably surpassing 200,000, U.S. health officials said Monday."It's accurate to say that there are probably several hundred thousand people that have been impacted by this flu," said Tom Skinner, a spokesman for the U.S. Centers for Disease Control and Prevention. "But that's in line with what we would see with seasonal influenza if we had the number of cases we are reporting right now."And while the outbreak continues to wane, new cases will continue to emerge, Skinner said.On Monday, the CDC was reporting a total of 10,053 cases in all 50 states and the District of Columbia, including 17 deaths. The agency has said in the past that confirmed cases of H1N1 swine flu represent about one in 20 of actual cases, bringing the total number of cases to about 200,000.

Twins with different dads

2009-05-23T22:21:00.002+05:30

A Texas woman is found to have a twins but of different dads. She gave birth to twins of different fathers nearly a year ago. Both of them have similar appetites. They like to play with their older brothers. They like to play with each other. How did it happen? Every month a woman's ovary releases one egg that can be fertilized by one sperm. But in this case, a pair of eggs emerged.Sperm, meanwhile, can remain alive and well and viable for up to five days in the reproductive tract. Thus a woman can have sex with different men within those five days and the sperm “just kind of hang out there waiting for the egg to be released,” Dr. Hilda Hutcherson, Clinical Professor of Obstetrics and Gynecology at Columbia University.

Missing human ancestor found

2009-05-23T21:28:00.002+05:30

A discovery of a 47 million-year-old fossil primate that is said to be a human ancestor was announced and unveiled at a press conference in New York City. Known as "Ida," the nearly complete transitional fossil is 20 times older than most fossils that provide evidence for human evolution. It shows characteristics from the very primitive non-human evolutionary line (prosimians, such as lemurs), but is more related to the human evolutionary line (anthropoids, such as monkeys, apes and humans), said Norwegian paleontologist Jørn Hurum of the University of Oslo Natural History Museum. However, she is not really an anthropoid either, he said.

Sleep and lose your weight

Thermal-imaging cameras spot flu fevers

2009-05-03T08:53:00.003+05:30

To screen passengers for swine flu and other contagious diseases, some airports use thermal imaging cameras to see whether travelers have fevers, without having to stick thermometers in their mouths. The devices are just like regular cameras, except that instead of recording light that objects reflect, these cameras are sensitive to heat. They can even work in the dark. Recordings from these cameras show up on video screens with hotter objects looking brighter. The systems are very sensitive, measuring temperatures down to a fraction of a degree Fahrenheit, said Andrew Sarangan, an associate professor in the University of Dayton's electro-optics program.

Swine flu

2009-05-03T08:32:00.003+05:30

Swine influenza is a respiratory disease of pigs first isolated in swine in 1930, according to the Centers for Disease Control and Prevention. The illness is caused by four different type A influenza strains that can cause outbreaks in pigs, though subtypes H1N1 and H3N2 seem to be more common. The death rate among pigs is low, with most infections occurring in the late fall and winter. Symptoms of infected pigs include fever, depression, coughing (barking), sneezing, difficulty breathing, red or inflamed eyes, lack of appetite and discharge from the nose or eyes. Read more>>

Mexico fights swine flu with pandemic potential

2009-04-25T23:05:00.001+05:30

A new swine flu strain that has killed as many as 68 people and sickened more than 1,000 across Mexico has "pandemic potential," the World Health Organization chief said , and it may be too late to contain the sudden outbreak. This swine flu and regular flu can have similar symptoms — mostly fever, cough and sore throat, though some of the U.S. victims who recovered also experienced vomiting and diarrhea. But unlike with regular flu, humans don't have natural immunity to a virus that includes animal genes — and new vaccines can take months to bring into use. Read more>>

Unidentified Flying Object (UFO)

2009-04-04T12:54:00.001+05:30

We were the only car on a long stretch of rural highway between Paris and McKenzie, Tennessee. It was a Sunday night and my roommate and I were returning to college. We were talking and listening to the radio. Suddenly, we saw streaks of light coming from the top of our windshield. There was no noise. From inside the car, we could not see the source of the light. There were no other cars coming in either direction. We stopped the car on the road and got out. Directly above our car was a round disc-like object with windows. It had a raised dome "cock'pit" in the center of the top half. It was hovering and spinning effortlessly about 200 feet directly above us. It made a quiet whirring noise. The sparks of light had stopped. There were lights flashing on and off around the edges of the object. We watched for approximately two minutes as the object stayed right above us and our car. Suddently, the object went from standing still to a startling speed in 1 or 2 seconds. It was several miles away and made a 90 degree turn to the east without ANY loss of speed. My roommate and I got back in our car to finish our journey to school. We were speechless for about 10 minutes. That night on the 10 o'clock news, it was reported that there were identical sightings of the same object in six different states.

Cloning

2009-03-19T08:46:00.002+05:30

Cloning is the production of multiple, identical offspring. A clone is an animal who is genetically identical to its donor "parent". We now know that this can be achieved using cells derived from a microscopic embryo, a fetus, or from an adult animal. Cloning from adult animals was introduced to the public in 1997 when scientists announced the birth of Dolly, the first animal cloned in this way. There have now been hundreds of clones produced from skin cells taken from adult sheep, cattle, goats, pigs and mice. The real key to cloning an adult animal is the ability to reprogram the skin cell nucleus and cause it to begin developing as if it was a newly fertilized egg

Scientists are sure of achieving major medical breakthroughs by the stem cells. Scientists are striving to create therapies that rebuild or replace damaged cells with tissues grown from stem cells and offer hope to people suffering from cancer, diabetes, cardiovascular disease, spinal-cord injuries, and many other disorders. By drawing on expert scientists, doctors, bioethicists, and others, the National Academies have examined the potential of stem cell technologies for medicine and provided a forum for discussing the ethical implications and moral dilemmas of stem cell research.

Technology

2009-02-16T15:01:00.008+05:30

Technology is a broad term that refers both to artifacts created by humans, such as machines, and the methods used to create those artifacts. More broadly, technology can be used to refer to a way of doing something or a means of organization: for instance, democracy might be considered a social technology. Technology comes from the Greek technologia, which is a combination of “techne”, meaning “craft”, and logia, meaning “saying”. So technology might be considered the articulation of a craft. The word is also used to describe the extent to which a society can manipulate its environment. When the word “technology” is used today, it is most often used to refer to high technology – computers, cell phones, rockets – rather than technology in general. But when anthropologists use the word “technology,” they go all the way back to the controlled use of fire (from about 500,000 – 1 million years ago), the invention of the wheel (c. 4000 BCE), and beyond. The first technological tools were simple hand-axes made by our hominid ancestors millions of years ago. The earliest technological divisions are from mankind’s early history, divided into the Stone Age, the Bronze Age, and the Iron Age depending on the primary tool and weapon-making material at the time. Each building material is superior to the one before it, but more difficult to develop requisite metallurgical techniques. The Iron Age began in about 1400 BCE. Since the formulation of the Scientific method in the 15th century, technological progress has apparently been accelerating. Some technologies developed since then include the telescope, the microscope, the clock, the engine, the electric generator and electric motor, radio, nuclear powerand weapons, television, computer, and many others. Technological development continues strongly today, fueled by the multibillion-dollar economies of the world’s most prosperous nations. The hottest developments in technology today are happening in computers, nanotechnology, materials science, renewable energy, entertainment, space travel, and medicine. Philosophers as well as laypeople often debate whether or not technological progress is, on the whole, a good thing for humanity. On the pro-technology side of the spectrum are techno-progressivists such as transhumanists, on the anti-technology side are anarcho-primitivists, and Neo-Luddites.
