Black holes can heat surrounding gases to more than a million degrees. The high-energy X-ray radiation from this gas can be polarised and vibrating in a particular direction.
The mission named The Imaging X-ray Polarimetry Explorer (IXPE) with three space telescopes will measure the polarisation of Cosmic X-rays of surrounding gases.
The mission set for launch in 2020. For the first time it allows astronomers to explore astronomical objects such as stellar and supermassive black holes, neutron stars and pulsars.
This will allow scientists to find the causes for rise of black holes.
Leishmaniasis
Historically the disease is known as “Aleppo boil”. Recently it becomes a problem among Syrian refugees.
It is caused by protozoan parasites of the genus Leishmania and is spread by the bite of the sandfly.
The disease will result in skin ulcerations and then presents with fever, low red blood cells, and enlarged spleen and liver.
It may occasionally spread to internal organs with fatal consequences.
New technique to detect jaundice
Jaundice, also known as icterus, is a yellowish or greenish pigmentation of the skin and whites of the eyes due to high Bilirubin levels.
Levels of Bilirubin in blood are normally below 1.0 mg/dL and levels over 2-3 mg/dL typically results in jaundice.
Bilirubin is a yellow compound that occurs during the body's clearance of waste products that arise from the destruction of aged red blood cells.
High Bilirubin levels may be due to excess red blood cell breakdown, new born jaundice, thyroid problems, liver diseases such as cirrhosis or hepatitis or blockage of the bile duct.
IIT-Guwahati researchers devised a new technique that uses thumb imprint to detect Bilrubin levels and thereby diagnose Jaundice.
