The number one way to improve your memory
Memory loss is the single biggest fear for Americans over the age of 55. And it’s understandable: over 4 million currently suffer from Alzheimer’s disease, and those numbers are expected to quadruple by 2050, according to the Alzheimer's Foundation. That may be why products promising to improve your brain function are flooding the market. Sudoku and crossword puzzles are said to improve memory association skills, though critics believe only when put to task by those puzzles. Ginkgo infused soft drinks line the grocery aisle, ever since the root was suggested to combat dementia (it doesn't). Even celery has been loosely linked to mental acuity. But the truth is there’s not enough hard evidence that any of these things really work.
In fact, there’s only one practice that’s been proven, without question, to preserve your memory: exercise. "Aerobic activities tend to show larger effects than non-aerobic activities," University of Pittsburgh psychologist Kirk Erickson tells Yahoo.
Working up a sweat helps your mind stay fit better than any crossword puzzle--unless you're doing that crossword on a treadmill.
The good news is that you don’t need to run a marathon. Just walking six miles a week can ward off memory disorders caused by aging, according to Erickson's research published this month in the medical journal Neurology. "It appears that if people start exercising their memory may improve and if you continue to exercise, that might delay, or offset, the age-related decline in memory," he explains.
And you don't need to lift any heavy barbells either. Erickson and his team monitored 300 senior adults over a period of 13 years, and found that those who walked between 6 and 9 miles a week—whether to work or with the dog--had half the brain deterioration of those who didn’t. "Exercise seems to enhance some of the more fundamental properties of our brain," Erickson explains. "It increases the growth of new cells and improves cellular processes associated with learning and memory." To put it simply, walking keeps your gray matter from shrinking. And the more matter, the more mind.
Another study published earlier this year suggests exercise can actually help your brain grow. A moderate workout may generate new brain cells. And not just any brain cells, but cells that specifically help to distinguish between memories, so each recollection stands out. It’s the kind of function you rely on every day, says Tim Bussey, one of the authors of the Cambridge University study. "[These cells help with] remembering which car parking space you have used on two different days in the previous week."
But exercise isn't the only way to keep tabs on your parking spot. There are some supplemental practices that doctors recommend in addition to a regular walk-a-thon. Diets rich in Omega fatty acids are instrumental in keeping your brain from aging. Two servings of salmon a week, provides ingredients that support brain tissue and enhance nerve cell function. Balancing fish with the other elements of a Mediterranean diet, like fruits and vegetables, has been found to lower the chances of cognitive decline. When it comes to memory retrieval, self-testing can be beneficial. In other words, pausing between paragraphs of an article and asking yourself to paraphrase the information, or repeat a fact. It can't hurt if that article is written in another language. Bilingualism, says one new study, helps ward off Alzheimer’s for up to four years. But it doesn't prevent the disease altogether. Your best bet: Walk it off.

Brain Wave
What is the function of the various brainwaves?
It is well known that the brain is an electrochemical organ; researchers have speculated that a fully functioning brain can generate as much as 10 watts of electrical power. Other more conservative investigators calculate that if all 10 billion interconnected nerve cells discharged at one time that a single electrode placed on the human scalp would record something like five millionths to 50 millionths of a volt. If you had enough scalps hooked up you might be able to light a flashlight bulb.
Even though this electrical power is very limited, it does occur in very specific ways that are characteristic of the human brain. Electrical activity emanating from the brain is displayed in the form of brainwaves. There are four categories of these brainwaves, ranging from the most activity to the least activity. When the brain is aroused and actively engaged in mental activities, it generates beta waves. These beta waves are of relatively low amplitude, and are the fastest of the four different brainwaves. The frequency of beta waves ranges from 15 to 40 cycles a second. Beta waves are characteristics of a strongly engaged mind. A person in active conversation would be in beta. A debater would be in high beta. A person making a speech, or a teacher, or a talk show host would all be in beta when they are engaged in their work.

What is Nuclear Science?
Nuclear science is the study of the atomic world.
Penetration of radiation - a guide.
Investigation of matter at the atomic level is one of the most important fields of scientific research.
Radioactive decay
Radioactive decay is the spontaneous radioactive disintegration of an atomic nucleus resulting in the release of energy in the form of particles (for example, alpha or beta) or gamma radiation, or a combination of these.
Radioactive decay is one process through which unstable atoms can become more stable.
Penetration of radiation
In alpha decay, a positively-charged particle is emitted from the nucleus of an atom. An alpha particle consists of two protons and two neutrons (a helium-4 nucleus). Although alpha particles are normally highly energetic, they travel only a few centimetres in air and are stopped by a sheet of paper or the outer layer of dead skin.
Beta decay
In beta decay, a particle is emitted from the nucleus of an atom. A beta particle is an electron with either negative or positive electric charge. Beta particles may travel metres in air and several millimetres into the human body. Most beta particles may be stopped by a small thickness of a light material such as aluminium or plastic.
Gamma decay
Gamma decay occurs because the nucleus of an atom is at too high an energy state. The nucleus falls down to a lower energy state, emitting a high energy photon known as a gamma particle in the process. Gamma particles travel in a wave-like pattern at the speed of light. They can only be stopped by a dense material such as lead, steel, concrete or several metres of water.
Nuclear science for agriculture
Sterile Insect Technique (SIT)
Fruit fly invasions into areas free of the pest disrupts Australia's $600 million a year trade in citrus, stonefruit, pome fruit, grapes and other crops. ANSTO uses irradiation to control fruit fly infestations in Australia.
Since 1988, SIT irradiation has been used by NSW Department of Primary Industries (DPI) at ANSTO to sterilise millions of laboratory reared fruit flies per week. When the sterilised flies are released in the target region and mate with wild flies of the pest population, they create no offspring. Gradually, the population is reduced. SIT is the primary pest management program for containment and eradication of Queensland fruit fly (Q-fly) outbreaks and is the only alternative to spray applications of toxic pesticides when eradication is required.
ANSTO continues to irradiate these insects for the Tri-State SIT program (NSW, VIC and SA governments, industry and matching Commonwealth funds) on a weekly basis for up to nine months of the year, and at other times when research into improving SIT is being carried out by the DPI and others.
SIT is also used overseas. For example, the sterile insect technique was used to eradicate the medfly from Chile.

Anger Control: Keeping Anger in Its Place
By Madeline Vann, MPH
Medically reviewed by Cynthia Haines, MD Print Email
Anger can be a pulse-raising response to other people’s behavior, but it can also be triggered by your own thoughts and memories. It is rooted in a basic, biological instinct that empowers us to defend ourselves from a threat. But in the modern world, anger must be controlled or it can result in dire consequences.
People who have a hard time coping with anger may need — or be ordered to — anger-management training.

All Swine Flu Articles
These are articles about Swine Flu. There have three main topic which are Swine Flu Basics, Swine Flu Prevention and Swine Flu Management.
Bagi negara kita, Selsema Babi ,Influenza A(H1N1) masih belum reda, Boleh ikuti perkembangan semasa melalui laman web rasmi Kementerian Kesihatan Malaysia, influenza A(H1N1).
p/s -Sebenarnya dah lama na simpan semua pasal H1N1...kebanyakan sumber suratkhabar, tapi semua di blog satu lagi tur...mungkin na pernah diuji dengan ujian di mana 50% diri na di dunia dan 50% di alam kekal dulu menyebabkan na begitu peka dengan H1N1
[na negative H1N1, cuma simptom ajek yang sama dgn simpton H1N1]
