Galaxy 13.4 billion years away breaks cosmic distance record
An international team of astronomers have shattered the cosmic distance record by discovering the farthest galaxy ever about 13.4 billion light-years away, from a time when the universe was just 400 million years old after the Big Bang. The Galaxy which has been named "GN-z11" is located in the direction of the constellation of Ursa Major.
The team of astronomers who have discovered the galaxy includes scientists from Yale University, the Space Telescope Science Institute (STScI), and the University of California. The team’s findings have been accepted for publication in an upcoming edition of the Astrophysical Journal.
The combination of Hubble’s and Spitzer’s imaging shows that GN-z11 is 25 times smaller than the Milky Way and has just one per cent of our galaxy’s mass in stars. GN-z11 is growing fast, forming stars at a rate about 20 times greater than our galaxy does today.
Earlier, the team had estimated GN-z11’s distance by determining its colour through imaging with Hubble and Nasa’s Spitzer Space Telescope. Now, for the first time for a galaxy at such an extreme distance, the team used Hubble’s Wide Field Camera 3 to precisely measure the distance to GN-z11 spectroscopically by splitting the light into its component colours.
How distance in space is measured ?
Astronomers measure large distances by determining the “redshift” of a galaxy. This phenomenon is a result of the expansion of the universe; every distant object in the universe appears to be receding from us because its light is stretched to longer, redder wavelengths as it travels through expanding space to reach our telescopes. The greater the redshift, the farther the galaxy.>Login To Save for Revision
- Air India operates ‘world’s longest all-women flight’
Air India the flag carrier airline of India has set a world record as it flew the "world's longest" all-women operated and supported flight, ever.
The flight, travelled a non-stop journey of around 14,500 kilometre between Delhi and San Francisco in close to 17 hours. The flight was operated as part of International Women's Day celebrations.
This was for the first time, on the world’s longest non-stop flight, that entire flight operations from cockpit crew to cabin crew, check-in staff, doctor, customer care staff, ATC (air traffic control) and the entire ground handling were handled by women.
The flight was under the command of Kshamta Bajpayee and Shubhangi Singh, along with First Officers Ramya Kirti Gupta and Amrit Namdhari. Air India has about 3,800 women employees, including pilots, cabin crew, engineers, technicians, doctors, security personnel and executives.>Login To Save for Revision
- New categorisation system for industries based on Pollution Index
Ministry of Environment, Forest and Climate Change (MoEFCC) has released a new four-colour classification scheme for industries based on their pollution potential.
The criteria for categorising industrial sectors based on the Pollution Index, which takes into account emissions (air pollutants), effluents (water pollutants), hazardous waste and consumption of resources.
The Pollution Index (PI ) of any industrial sector is measured from 0 to 100. Increasing value of PI denotes the increasing degree of pollution load from the industrial sector.
Under the new categorisation system :-
(1) Industries that pollute the most have been put in the red category.
(2) Industries that pollute moderately have been put in the orange category.
(3) Industries with low pollution load have been placed in the green category.
(4) Industries that operate without causing any pollution have been categorised as white.
Classification of Industries :
(A) 60 industries, including sugar, thermal power plants, paints and others, which have a pollution index score of 60 and above, will be in the red category.
(B) 83 industries like coal washeries and automobile servicing which have scores ranging between 41-59 will be in the orange category.
(C) Industries like aluminium utensil manufacturing and dal and flour mills, which have a pollution index score of between 21 and 40, have been kept in the green category.
(D) 36 industries like air coolers and cotton and woollen hosiery, which have a pollution index score of upto 20, have been kept in the white category.
Advantages of the new system :
The existing system was creating problems because it did not reflect the actual pollution caused by the various units but the new system categorises Industries based on their pollution load.
White industries, which are practically non-polluting, will not require Environmental Clearance (EC) and Consent. That will help them get funds from lending institutions.>Login To Save for Revision

- Indian scientists develop Herbal drug to treat dengue
Indian scientists have developed, a herbal medicine against Dengue, which accounts for 50 per cent of the global population estimated to be at risk from the disease. The drug was developed using alcoholic extract of Cissampelos pariera Linn (Cipa extract) derived from velvetleaf, a species of flowering plant.
The project was undertaken jointly by the Department of Biotechnology (DBT), under the Ministry of Science and Technology, the International Centre for Genetic Engineering and Biotechnology and Ranbaxy Research Laboratory, and employed traditional Indian medicine system Ayurveda.
Clinical results : The drug proved to be potent inhibitor of all four Dengue Virus (DENVs). The preliminary evaluation of the clinical relevance of Cipa extract showed it had no adverse impact on platelet count and RBC viability. It also showed no evidence of toxicity in Wistar rats, when administered doses as high as two grams/kilogram body weight for up to a week.
Scientists are now gearing for the next step, which is to hold clinical trials and toxicity studies of the drug after approval from Union Ministry of Ayush and Drug Controller of India (DCI) for commercial production.
Dengue : Dengue, a mosquito-borne viral disease which poses a significant global public health risk. India represents 50 per cent of the global population estimated to be at risk of dengue. Severe dengue can prove to be potentially fatal and cause very high virus load, reduction in platelet counts and haemorrhage.>Login To Save for Revision
- Four ‘extinct’ plant species rediscovered
4 species of Impatiens (Kasi Thumba) plants that were believed to have gone extinct many decades ago were rediscovered from the Western Ghats recently.
The rediscovered plants, Impatiens concinna, Impatiens sasidharanii, Impatiens neo-modesta , and Impatiens sasidharanii var hirsuta , were found to have great medicinal values. These plants, usually found 2,000 ft above sea level, are short-lived and will be seen only one quarter of a year.
A team of researchers led by K.M. Prabhukumar and Indira Balachandran, taxonomist and director respectively of the Centre for Medicinal Plants Research, Kottakkal Arya Vaidya Sala made the rediscovery during explorations at Dhoni Hills of Palakkad and Nelliampathy.
Facts to know :
(1) Impatiens concinna, found 6,000 ft above sea level, was discovered first time in Kerala. It was described as critically endangered in an article published in the Current Science
(2) Impatiens neo-modesta was found from the peaks of Nelliampathy.The findings were published in the Italian journal Webbia: Journal of Plant Taxonomy and Geography.
(3) Impatiens sasidharanii var hirsuta and Impatiens sasidharanii were found from Nelliampathy forests . They have been named after N. Sasidharan, former scientist of the Kerala Forest Research Institute.>Login To Save for Revision

- Gender gap in jobs, wages remain unchanged in 20 years: ILO report
International Labour Organization has released a report titled - "Women at Work: Trends 2016" which says that gender equality in the workplace remains elusive.
The report highlights that millions of women worldwide are not getting the same kind of quality, well-paying jobs as men.
New data in 178 countries present a gloomy picture of the current state of working women. The report shows the gender gap in employment, wages and social protection has changed little in 20 years.
The report says that women are overrepresented in clerical service and sales work, which are among the lowest paying jobs.
However significant progress has been made by women in education during the past two decades, but this has not translated into improvements at work.
