Battery-free Super Tiny Sensor that could Save Your Life
Tracking concentration of gas, checking organic compounds and chemical liquid, detecting various pollutants on food, even monitoring heartbeat are increasingly demanding for industries. Furthermore, smaller in size and less power consumption are particularly needed in the sophisticated industry for the next time future.
GE Global Research has taken the oportunity to meet those expectations even going further for battery-free and RFID based sensors.
Tiny sensor even smaller than a penny
Because it is no battery needed, small size can be met and low-cost manufacturing can satisfy the users. "Small size, low-cost and selective chemical capabilities will provide acceptance from many applicants," The researcher said.
Sensors are chemically and biologically coated to obtain numerous response to detect and measure chemical in different mixtures and circumstances.
Smartphone Camera to Monitor User's Vital Signs on Research
Researchers at Rice University try for further technique to find health-tracker application for smartphone and computers based on user's skin color. A new algorithm is developed to detect skin tone variation caused by blood circulation to determine pulse and breathing rates.
A way to measure physiological processes under user skin monitors changes at the skin surface, known as photoplethysmography (PPG), using a camera to track vital signs.
The PPG signal is extracted from four regions marked on the face
The algorithm, called DistancePPG, is measuring the eyes, nose, and mouth separately. Vital signs are estimated by the average of blood perfusion and incident light intensity.
However, it remained relatively inaccurate when user were moving, even talking and smiling. These movements changed the facial light and difficult to detect user signal, as said by researchers.
Banana Skin Gives New Hope for Cancer Research
Bright blue rings found under ultraviolet light on the peels of ripe bananas gives new improvement in studying how organisms cleanse themselves of dying cells, this is announced by US and Austria scientists.
Nicholas Turro of Columbia University in New York, Bernhard Krautler of the Institute of Organic Chemistry at the University of Innsbruck, Austria, found that when chlorophyll ages and begins to disintegrate in banana peels, it does not change color in the spectrum of visible light, instead, it glows blue when observed under ultraviolet light.
Left picture is banana in daylight while right picture is banana that glows blue in UV light
Chlorophyll is the molecule that allows life on Earth. It is the integral part that makes plant can take a mixture of carbon dioxide, water and sunlight so they can be converted to oxygen, sugars and starches. The chlorophyll break down is a major contribution to the color changes in fall leaves, and also ripening apples and pears. But in ripening and rotting bananas, chlorophyll fades to be unique fades color, causing yellow bananas to glow blue when observed under ultraviolet light.
Light-blue glowing rings surround the dying cells on the skin of a ripe banana
Because the glowing molecules occur in close proximity to dying tissue, they promise for good sign for further study of the way organisms cleanse themselves of dying cells, or even programmed cell death as in cancer cells. And we hope it also gives good sign for cancer research in human body.
Watching Sport Show Can Trigger Heart Attack
Many people love sport show in TV. But it is worried that watching interesting sport show can trigger heart attack. This warning is intended especially for heart attack patients.
Research in China shows that watching sports competition like football can increase people to have heart attack. The conclusion is made after a group of men have heart attack when watching sport show.
According to researchers, the cause of heart attack during watching sports show is decreasing blood flow to heart.
38 men involved to the research have heart attack when watching sport show, both for live show or from television.
During watching sport show, blood flow in their coronary blood line is watched and analyzed using tool called "electrocardiography (EKG)" continuously to check blood flow to heart. Blood pressure is watched continuously during the show.
"For all, blood flow to heart is quite stable, but when there is part that makes men really interested and enthusiastic with, the blood pressure increases very fast and then blood cell raises causing obstacle and blocks the blood flow to heart. This factor triggers heart attack," one of the researchers said.
For that reason, the researchers give advice for sport show lovers to be able to control emotion when watching the show if they still want to have long life.
Military Night-Vision Goggles Will be applied for Commercial Flight
Pilots will have difficulties when flying airplanes in night or few light conditions. The pilot will not able to see clearly and this will harm airplane safety as well as passengers and also flight line circumstances. Today, researches in US Federal Aviation Administration are developing military-use-only night-vision goggles for civilian pilots.
The goggles are made by Nivisys, a manufacturer of thermal and night-vision equipment, have feature high-resolution, lightweight and easy-to-operate. The goggles operate from a wavelength of approximately 600 to 900 nm. Vision angle is 40 degree, focus distance start from 25 cm to infinity with one magnification.
An advantage of this device is that the goggles can be configured according to the pilot's face because it is easy to adjust to center of the pilot's eyes, 25 mm downward and upward and tilt angle to 10 degree that make the pilot to easily see airplane instrument panel when using the goggles.
Night-Vision Goggle made by Nivisys
The weight is only 514 gram make it very light thanks to aluminum material. Beside it, the goggles are using 2 AA batteries that last up to 40 hours.
We hope the goggles can make commercial flight airplane to be safer than before. Read More ..
Interesting Facts about Formula 1
Formula 1 is the most famous race car in the world; it consists of sophisticated things in technology or other aspects. Then, it is not surprising if you find interesting facts about Formula 1. Here are interesting facts about F1:
- F1 car can go from 0 to 160 km/h and back to 0 only in 4 seconds
- F1 engines last only for 2 hours of racing before blowing up, for market car usually can last until 20 years
- F1 engines usually rotate up to 18000rpm meaning that the piston traveling up and down 300 times a second
- An F1 car consists of 80.000 component, if it is assembled with accuracy only 99,9% the car can still start but with 80 wrong assemblies
- Aerodynamic and downforce design of F1 car is very important, even small plane can take off at slower speed of F1 car
- Without good aerodynamic and downforce system, F1 car can lose control and wheel spin only at 160 km/h while F1 car usually race at over 300 km/h
- Downforce produced by F1 car front and rear wings is very amazing. When the car reaches speed at 160km/h, it can generate enough downforce to equal it's own weight
- In a street race such as Monaco GP, F1 car downforce can provides suction to lift manhole covers. That's why, manhole covers have to be welded before the race
- Normal tires can last up to 60.000 - 10.000 km, while F1 tires are designed to last only for 90 - 120 km

The Moon is Getting Away from The Earth 3.8cm Every Year
The moon now is getting away from the earth at 3.8cm a year. But don't worry, that doesn't give affect to distance change from moon to earth at 385.000 km for long time.
How researches know about distance change of moon to earth? The method is by beaming laser from earth to reflector in the moon, then they count how long laser takes to reflect measured at a time laser is beaming.
Detecting moon movement has been possible because of photonics technology and Apollo experiment that still running. For 40 years, scientists have periodically pinged laser beam and measuring ping time.
The result, if you want to know, is 2.5 seconds, varying because moon's elliptical orbit results constantly changing distance. From the precise measurements, researchers have confirmed not only key tenet of Einstein's theory of relativity, but also have shown that the force of gravity is very stable and have discovered that the moon probably has a liquid core.
For almost 20 years from 1960's, astronomers measured distance from moon to earth by beaming laser from telescope of McDonald Observatory to retroreflector placed on the moon
Today, measuring moon distance to earth is done by observatories in US, New Mexico and France.

Interesting Facts that You Have to Know about Mars
1. Mars has the biggest mountain in our solar system
The mountain is called "Olympus Mons" and it's actually dormant volcano. The mountain is 15.5 miles height and 372 miles in diameter. As comparison, Mount Everest height is just about 5 miles. Mars also has the biggest canyon in our solar system, known as "Valles Marineris" which is 2500 miles long and 4 miles deep.
Olympus Mons is seen from above
Comparison between Mount Everest and Olympus Mons
2. People have always think about life on Mars because of the "canals" first seen by astronomers
This is why people always think about alien invaders coming from here, and not from Jupiter or Venus. Actually, Mars is one of the least habitable planets because freezing temperature, sun winds, and almost no atmosphere. The canals seen by astronomers are straight lines that scientists believe are evidence of water.

4. Compared to the other planets in our solar system, Mars is quite small planet
It is half the size of the earth. Mars also has a third of the earth's gravity, means that you can jump three times higher that your jump on the earth.
Comparison between Mars and Earth
5. In the 1970's, Viking orbiter took pictures that seems to be giant face and pyramid on the planet's surface in Cydonia region
The picture looks like Egyptian Sphinx and is 2000 feet high. This discovery made UFOlogists excited; scientists say that is just eroded mesas. Many people still believe that the face are too symmetrical, and think it is evidence of ancient alien.

6. Mars has the wildest weather in the solar system
It has tremendous wind storms, dust storms and small tornadoes. In 2001, a huge dust storm covered the entire planet for several earth days. Scientists are confused why planet with little atmosphere could have storm such that. They don't know what causes the storm, but there are more storms when Mars gets closer to the sun. When it's on the farther end of its orbit, there are icy clouds made of carbon dioxide and dust. This is also strange since Mars has no surface water.

8. Mars has two moons, and one of it has chance to crash with Mars
One of the moons, called Phobos, has close orbit and is dangerous to Mars. Someday, the gravitational force will pull and crash to Mars. The debris will stay in Mars' orbit and making a ring like Saturn. At the end, the debris will fall down to Mars' surface. Scientists don't know when this will happen, but they predict it is going to happen in the next 50 years.

Moon Landing; 40 Years of Giant Leap or Hoax?
"One small step for a man, one giant leap for mankind", that was legendary words spoken by Neil Armstrong on 1969 after first foot step on the moon. But after 40 years, many people state that moon landing is a hoax, especially after broadcasting documenter film "Conspiracy Theory: Did We Land on the Moon?" at Fox TV on February 15, 2001.
United States of America had an ambition to land man on the moon at time of cold war. When Soviet Union put Sputnik satellite into space, many people presumed that the satellite brought nuclear weapon to explode US. President of Kennedy, on 1961, ordered NASA to land man on the moon at anyhow before the end of 60's decade.
Actually, before the documenter film was broadcasted, experts analyzed moon landing evidences distributed by NASA. Many of them were analyzing that there were many awkward of the photos connecting to moon facts, the result showed that the photos were faked or made somewhere on earth or at least they stated that NASA distributed edited photos (someplace on moon or earth).
Some of famous evidences that they claimed as moon landing hoax are: there is no stars at moon sky although the weather is clear, American flag can wave despite no atmosphere on the moon (moreover air/wind), and objects on moon photos have cross shadow showing there is another light source beside the sun. You can read more in this site Faked Moon Landing. But NASA also has evidence to deny the accusation in this site Non-Faked Moon Landing. Besides it, there is another interesting site mention the hoax like in this site The Apollo Hoax, and also interesting site as denying Top 10 Apollo Hoax Theories.
This article is not to show you that moon landing is a hoax or one of mankind history. I have given you facts not only showing moon landing hoax but also facts of truth about moon landing. This article is intended to celebrate 40 years of amazing history that take attention all people because it was first time mankind subjugate the space. So after 40 years, is moon landing a giant leap for mankind or a hoax? It's only you who can judge it.
