New Disease detection technique with naked eyes

Scientists have developed a new ultra-sensitive sensor test which is also 10 times cheaper to detect the early stages of several cancers and viruses, including HIV, with the naked eye.

What is the technique?

The new visual sensor technology detects biomarkers which are produced in the body when it is infected with certain disease.  The sensor works by analyzing serum, derived from blood, in a disposable container. The color of the liquid changes to give either a positive or negative result. This change in color can be easily seen with naked eyes.

How it can help?

The test is 10 times cheaper that existing gold standard tests. It can detect onset of diseases like certain cancers and HIV in early stages.


Next-gen sequencing approach to identify diseases from bone samples

A new technology that uses a next-gen sequencing approach, including hybridization capture technology, to analyze gene sequences within seconds to identify diseases accurately. Scientists used the technique to identify tuberculosis (TB) genes in a 19th century female skeleton found in a crypt in Leeds.

How this technology will help?

  • It will help in understanding how the disease has evolved over time.
  • It will help improve treatments and vaccines.


Rs 4,000 crore plan to fight Japanese Encephalitis

The Union Cabinet of India sanctioned a Rs 4038-crore comprehensive multi-pronged plan for prevention and control of Japanese Encephalitis (JE) and Acute Encephalitis Syndrome (AES) in the country.

States where this plan will be implemented:

  • Uttar Pradesh
  • West Bengal
  • Tamil Nadu
  • Bihar
  • Assam

The plan will be implemented within five years from 2012-13 to 2016-17.

What is Japanese Encephalitis?

  • Japanese Encephalitis is a viral disease spread by the mosquito carrying the virus.
  • The disease is mainly prevalent in Southeast Asia and the Far East.

What are the reservoirs and vectors of this virus?

  • Domestic pigs and wild birds (herons) are reservoirs of the virus.
  • Amongst the most important vectors of this disease are the mosquitoes Culex tritaeniorhynchus and Culex vishnui.
