A Sensor Which Could See Without An Eye
An eyeless sensor has been invented. Inspiration is taken from the ability of the human skin to 'see' colors and objects. This would make optical technologies available in the market obsolete. This futuristic device created by Lenoid Yaroslavsky. He is the scientist at Tel Aviv University. This would help in understanding how this primal inherent aptitude might have developed over millions of years. This behavior can be seen also in plants and...
New Reprogramming Method To Generate Stem Cells (Part-2)
Eggan’s team worked on the patients skin cells. They put them under four genetic factors found in the developing embryo. This process made cells to look and behave like embryonic stem cells. Such types of reprogramming techniques were also used earlier to create stem cells from skin cells. But in this new experiment the cells were generated from a patient body. These cells were given a name of IPS cells - Induced Pluripotent Stem cells. ...
New Reprogramming Method To Generate Stem Cells (Part-1)
Scientist has successfully achieved to derive stem cells from the skin of an eighty two year old patient suffering from ALS - amyotrophic lateral sclerosis. Through this the scientists have found a new method to study the degenerative motor disease. It will also help them to test new treatment drugs. Finally this new technique will bring a new revolution in cell-replacement therapies. All this was achieved when scientists were using new te...
British Company Unveiled Hydrogen Fuelling System (Part 2)
The second major component is its internal combustion generator. The function of this generator is to convert the gas into electric power. This electric power could be used for any domestic need. This station is being publically demonstrated heating, cooking and operating a fridge in Sheffield. The critical element of this is how much it would cost to put such a refueling station in your home. The technology is very plausible but there a...
British Company Unveiled Hydrogen Fuelling System (Part 1)
A new hydrogen refueling station has been introduced by the ITM - British company. The company is leading innovator within the alternative energy source industries. This station could be installed in the home and would be a best alternative to visiting a petrol station. To comply with this new technology hydrogen-powered cars are also going to set in production. The interesting thing about this is that this could also be used for heating an...
Tiny Scanner Will Be Used To Monitor Astronauts Mental Health
The working schedules are extremely heavy in space as they remain in touch with the earth centers with the video connections and astronauts have a little time to enjoy their private time. The situation is very tense in space strong mental health is needed there. In a near future, doctors would be able to look into an astronaut space life through portable brain scanner. This could be highly helpful in examining the mental health of the astr...
Self Cleaning Membrane Avoids The Attention Of Cells (Part 2)
The temperature was lowered down to 25 C. At that temperature hydrogel started absorbing water and swelling and then it was again raised up to 37 C. By doing in this way, researchers saw that around 80% of the attached cells dropped by. The fellow researchers of Giant repeated the temperature change procedure every 60 minute, and continued to do it for four hours. After the experiment the researchers said that a sensor coated fully with the...
Self Cleaning Membrane Avoids The Attention Of Cells (Part 1)
The surface which could clean it by itself and combat with the immune response of the body could increase the life of biosensors inside the human body. The sensors implanted beneath the skin give continuous information therefore this technique is considered as the easiest and simplest way to get reports on chronic diseases like diabetes. The implanted sensors continue working in the right manner as long as its surface remains clean. But...
Advanced PET Scanner To Early Diagnose The Disease (Part 2)
The imaging results of the semiconductor-based detectors are much better than the conventional detectors. The reason is that these semiconductor-based detectors are smaller and thinner in size and could be easily adjusted and arranged than others. This advancement in technology renders higher spatial resolution and images with less noise and without irrelevant information. This device also carries depth of interaction (DOI) which is a detectin...
Advanced PET Scanner To Early Diagnose The Disease (Part 1)
The study on PET brain scanner showed that this technology could be advanced more in quality and spatial resolution of PET imaging. This is said by the team of medical researchers. PET stands for positron emission tomography. This is a prototype scanner in which semiconductor detectors are used. This prototype has already been used for characterizing the brain disorder disease – epilepsy – and nasopharyngeal cancer. It proved successful...
Animal Excreta As A Source To Produce Electricity
American scientists say that it could be very useful to use animal faeces as a fuel source. Through this fuel-source energy could be produced especially in the form of electric power. It is also being claimed that if it be done this would generate three percent of the energy needs of the whole North America. A research work is going on in the Institute of Physics journal Environmental Research Letters. It is reported that this process would...
Discovery Of Cost Effect Bio Fuels
The young students and professors who are doing research work in Rose-Hulman Institute of Technology made a discovery on natural vegetable oils. They said that these oils are having the capacity to be a substitute for motor oil mixtures generally used as lubricants for two-stroke engines. They succeeded on developing and examining the various methods to make cost-effective bio-fuels derived from different origins. They remained busy on cond...
New Technology Helping In The Research Work On Penguin Lives
Scientists succeeded to develop a technology which would be very useful in the research work being made on penguin lives. According to the news this new technology will monitor the movement of the endangered penguins without disturbing their private lives. The researchers working in the University of Bristol have done that job. By adopting this new technology scientists would be able to get all the information they needed from far away. The...
Cure Has Been Invented For Blindness
Good news for the eye-patients who have gone blind due to retina damage or disease. German scientists have successfully created wireless bionic eyeball recently, which will restore vision of that kind of eye-patients. It took 12 years of deep research work by the scientists to create this new prosthetic device for the eye-patients. This is named as “bionic eyeball” and it would be fully implanted in the body. This will bypass the dam...
