  1. Sorry Moderator..It is not an advertising link.I just give original source to help others if they need more details about the topic.
  2. Spending time with loved ones or things we get positive feelings and in during exams or bad things we get fearful or negative response. This is all due to almond shaped structure in brain called amygdala. This was found out by MIT researchers. Two populations neurons in the brain responsible for the good and bad feeling to us according to the researchers. These neurons pass the information to other regions in brain that create feelings to us. This is very helpful to cure the people who have mental illness. Advertising link removed by Moderator
  3. All of us have many dreams every night.Why do we only remember some of them? And what determines which ones we remember?
  4. A team of researchers from the University of Cambridge have unravelled one of the mysteries of electromagnetism, which could enable the design of antennas small enough to be integrated into an electronic chip. These ultra-small antennas – the so-called ‘last frontier’ of semiconductor design – would be a massive leap forward for wireless communications. The researchers have proposed that electromagnetic waves are generated not only from the acceleration of electrons, but also from a phenomenon known as symmetry breaking. These new observations of radiation resulting from broken symmetry of th
  5. Researchers proposed the application of egg white as the size-controlling agent in the production of oxide nanoparticles. Egg white is a natural biomaterial that contains high amount of amino acids and various proteins such as albumin and lysosome. Amino acids have a structure that can play the role of stabilizer and size-controller in the synthesis of nanoparticles.The aim of the group was to synthesize and evaluate the toxicity of cerium oxide (CeO2) nanoparticles through green chemistry method as a safe and novel approach. Non-toxic cerium oxide nanoparticles have been produced through this
  6. A spice commonly used in curry could help erase bad memories, according to a study.Curcumin, a bright-yellow compound found in the root of the Indian spice turmeric, prevented new fear memories being stored in the brain, and also removed pre-existing fear memories, researchers found.It is hoped that the findings will help develop treatments for people suffering with psychological disorders. Psychologists from The City University of New York trained rats to become scared when they heard a particular sound. Scientists assumed the creatures were frightened when they froze.Hours later, when the s
  7. Scientists have developed tiny nanoneedles that have successfully prompted parts of the body to generate new blood vessels, in a trial in mice.Their nanoneedle technique could ultimately help damaged organs and nerves to repair themselves and help transplanted organs to thrive. The nanoneedles work by delivering nucleic acids to a specific area. Nucleic acids are the building blocks of all living organisms and they encode, transmit and express genetic information.The nanoneedles are tiny porous structures that act as a sponge to load significantly more nucleic acids than solid structures. T
  8. A new research was carried out on chocolate. Researchers have found a way to make chocolate more healthier and tastier with greater levels of anti-oxidants.They said that a pod-storage step before the beans were even fermented to see whether that would have an effect on the polyphenol content.Researchers 300 pods into four groups that were either not stored at all or stored for three, seven or 10 days before processing.This technique is called ‘pulp preconditioning’. After each storage period passed, fermentation and drying were done as usual. The seven-day storage resulted in the highest anti
  9. Two senior engineering majors Seth Robertson (23) and Viet Tran (28) from George Mason University appear to have invented and built a way to use sound waves to put out fires in seconds . It looks to be successful in beginning testing.This extinguisher emits low-frequency sounds in the direction of the fire.This new design of extinguisher simply emits low-frequency sounds in the direction of the fire.They have constructed it using a power source, amplifier, sound generator, and focusing tube.It has currently cost around $600.

  10. Packing peanuts are used worldwide as a perfect solution for shipping, they are notoriously difficult to break down, and only about 10 percent are recycled. Due to their low density, huge containers are required for transportation and shipment to a recycler, which is expensive and does not provide much profit on investment.A team of chemical engineers at Purdue University have shown now how to convert waste packing peanuts into high-performance carbon electrodes for rechargeable lithium-ion batteries that outperform conventional graphite electrodes, representing an environmentally friendly app
  11. UCLA researchers create new method that targets tumors with the same effectiveness but a significant reduction in both side effects and cost. Pancreatic cancer: Pancreatic cancer, a devastating disease with a five-year survival rate of 5 percent, is difficult to detect early and symptoms do not usually appear until the disease is advanced. As a result, many people are not diagnosed until their tumors are beyond the effective limits of surgery, leaving chemotherapy as the only viable treatment option. The chemotherapy drug most often used for pancreas cancer is gemcitabine, but its impact is o
