Ebola Virus Disease (EVD) is an acute, serious disease which may be fatal if untreated.
Formerly it was known as Ebola Haemorrhagic fever. It is caused by Ebola virus.
This disease is named so after it first occurred in village near Ebola river (Democratic Republic of Congo).
Incubation period of EVD is 2 to 21 days.
Signs and symptoms of EVD are following:
- Onset of fever
- Muscle pain
- Sore throat
The above said symptoms are followed by:
- Symptoms of impaired kidney and liver function
- Oozing from gums, blood in stools
Ebola is transmitted in human population from ill or dead animals such as chimpanzees, gorillas, fruit bats, monkeys, forest antelopes and porcupines through blood, secretions, organs and other bodily fluids.
Ebola is transmitted from human to human under the following circumstances:
- Direct contact with the blood, secretions, organs and bodily fluids of infected people and through contaminated surfaces and materials.
- Close contact with patients.
- Men who have recovered from the disease can still transmit the virus through their semen for up to 7 weeks after recovery from illness.
Till now there is no proven treatment available for EVD. But supportive treatment such as oral and IV fluids are given to treat specific symptoms.
Zygote is the structural and functional unit of life. This is a single cell which continuously undergoes cell division to give rise to embryo.
Adult human body is a machine in which each part is specialised for its intended function. However, there are some organs which undergo wear and tear periodically and which is required to be repaired and replacement of lost cells. For this purpose, every organs retain a small population of cells (reserved) that do not differentiate. When needed these cells proliferate, repair, renew and regenerate the organs. And these reserved cells are known as stem cells.

Antarctica may seem a motionless and frozen landscape, yet hundreds of miles down the Earth (earth’s mantle) is moving rapidly changing the shape of the land at a rate that can be recorded by Global Positioning system (GPS), according to a new research.
According to Global Positioning System (GPS) data collected the land in this region is actually rising at a phenomenal rate of 15mm per year – much greater than can be accounted for by the present-day elastic response alone.
For the first time researchers have shown that how the mantle below the Earth’s crust in the Antarctic Peninsula is flowing much faster than expected, probably due to subtle changes in temperature or chemical composition.
This means it can flow more easily and so responds much more quickly to the lightening load hundreds of miles above it, changing the shape of the land.
Astronomers claimed that they have found a star born from the same cloud of gas as our sun 4.5 billion years ago. This star is little bigger than our sun and its surface is also hotter than our sun. The researchers said that the chemical fingerprint of the new-found star is same as our sun.
Our sun has been formed from an immense cloud of gas and space dust that gave rise to 1,000 to 10,000 stars. Astronomers claimed that baby stars stayed clustered together for hundreds of millions of years but as these stars started growing up their cluster broke up and the individual stars began to drift apart.
“Stars that were born in different clusters have different compositions. If a star has the exact same chemical composition as our sun, that establishes that they were born in the same place,” said Ramirez is the lead author of a paper about the discovery that will be published June 1 in the Astrophysical Journal.
According to surveys there are about 100,000 stars we can look at in this way. In five or 10 years it could be as many as a billion,” he added.

About 1, 02, 9874 students have registered this year for the Senior Secondary School Examination (Class XII). The board conducted the examinations all over the country between March 1 and April 17 this year.
Joint Entrance Exam (JEE) Mains 2014 candidates will be required to submit a hard copy of their Class 12 qualifying mark sheet, on the day of the exam, to the invigilator at the exam centre before the beginning of the exam. Aspirants attempting the pen-and-paper based examination and the computer based examination will be required to submit their respective Class 12 qualifying mark sheet.
Candidates having completed their Class 12 examinations can submit their mark sheet, those attempting for Class 12 improvement exam can submit their improvement exam admit card and previous mark sheet, and those appearing for the Class 12 examination are to submit a copy of their admit card/ hall ticket. Before submitting the copy of the Class 12 qualifying examination document, candidates must write their JEE Main examination roll number on the document being submitted to the invigilator. Also note: students whose Class 12 result will be released after June 25, 2014, will not receive All-India-Ranking of JEE Main 2014.
