Benjamin Franklin wrote in a personal letter, “…in this world nothing can be said to be certain, except death and taxes!” Every minute on earth, 108 people die. Ultimately, everyone dies. It is not a matter of if, but when. Sadly, and due to a wide variety of reasons and circumstances, some seek death, considering it the only solution. Others try to delay the inevitable through good health. Still others tragically lose their lives through time and chance. Sometimes disease or other illnesses bring a death sentence, leaving a person with nothing to do but wait for the end.

Misplacing a cell phone or having one stolen is a horrible experience. We store a vast amount of personal data on our phones. From health or medical information, to photos, and payment details -- our phones hold intimate details of our lives.
Researchers have developed a new method to overcome one of the main issues in implementing a quantum cryptography system, raising the prospect of a useable 'unbreakable' method for sending sensitive information hidden inside particles of light.
Of the hundreds of moons in our solar system, Titan is the only one with a dense atmosphere and large liquid reservoirs on its surface, making it in some ways more like a terrestrial planet.
Engineers have built a device that mimics the surface of the eye in an attempt to make wearing contact lenses all day less irritating.The work was inspired in part by a graduate student's dry eyes. "As a student, I had to stop wearing lenses due to the increased discomfort," says Saad Bhamla, a Stanford University postdoctoral scholar in bioengineering. "Focusing my PhD thesis to understand this problem was both a personal and professional goal."
After NASA's New Horizons spacecraft made its nearest approach to Pluto in early July—a trip that lasted nine years and three billion miles—much information is still arriving about the solar system's most well-known dwarf planet. The craft passed close enough to take the clearest-yet images of the distant planet and its five moons, which have given astronomers a new perspective of its properties.
That's not Rudolph's nose, it's just a giant rock hurtling through space. NASA scientists calculate that asteroid 163899, also known as 2003 SD220, will make its closest approach to Earth on Christmas Eve, December 24, 2015.
One of the first things every new moon watcher learns is that, when observing the moon, timing is everything. You might think the best time to look at the moon with binoculars or a small telescope is when the moon is full, because it looks so big and bright. Well, that's usually the worst time of the month for observing the moon. That's because at full moon, the sun is high overhead on the moon's surface, making it look like the desert at high noon. Far better times are at first and last quarters, when the sun is shining obliquely across the moon's terrain, casting mountains and craters into high relief.
The future of data storage is likely to be found in nanometer scale, stable magnetic whirls called skyrmions, which behave like particles in magnetic thin films. But creating these whirls has been notoriously difficult, requiring carefully-engineered multilayers or very specific bulk materials.
Researchers have long sought to harvest renewable energy from the world around us. Now, scientists are turning inward. The beating of our hearts, the rush of our blood and the myriad chemical reactions that keep us alive are all potential energy sources. Experts are working to develop technologies that take advantage of the powerful biological ecosystems we already carry around with us.
If you're afraid of needles, here's some good news: you may not always be stuck with getting shots. At present, injections are the best way to deliver certain kinds of drugs. For example, vaccines and drugs like insulin are made of large molecules that you can't take orally because they would break down in your digestive tract. Some antibiotic and antiviral medications are also given as injections for this reason.
There is no denying, that we live in a material world and that first impressions count. Imagine a scenario where two job applicants with the same qualifications are being interviewed. One with good oral hygiene, a pleasant smile with pearly white teeth and minty fresh breath. The other with bad oral hygiene with stained and missing teeth, with bad breath. No prizes for guessing as to who gets the job. -By Dr.Dilan Fernando B.D.S.(SL)-
The main objective of Ayurveda according to Pandit Shiva Sharma is, "to maintain and promote physical, mental and spiritual health of the individual and the community". The other objective is, "to prevent disease and to treat, and to cure it when it appears" Even though the primary purpose of Ayurveda is to serve mankind, there are Ayurvedic texts that deal with the treatment of elephants, horses, cows and other animals (Salihotra Samhita), and also Vruksha Ayurveda that deals with the art of preservation and healing of plants -By P.L.N. de Silva - Former Chairman, Sri Lanka Ayurvedic Drugs Corporation.-
