ISRO DISCOVERS RED HIMALAYAN GLACIAL LAKE IN LADAKH ## इसरो लद्दाख के हिमालय मे लाल ग्लेशियल झील का पता लगाया है ##


Scientists from the ISRO have reported
the existence of a new glacial lake in
the Northeast Himalayas.
On the basis of satellite images taken
over the past 20 years, it is said to have
reddish brown waters.
Location: 5060 meters above sea level, near the Zanskar valley, Ladakh
It is 11 kilometers from the nearest
village, and covers an area of
approximately 0.2 square kilometers.


The lake is being fed by a glacier, and the researchers suggest that it has either been formed or expanded due to glacial melt caused by climate change.

Red color

Due to the local geology and iron-rich minerals of the region, like hematite and goethite, that interact with snow and glacial meltwaters and subsequently deposits red suspension in the lake. The lake's unique geochemistry and the molecules reflect the light at longer wavelengths, making the Himalayan glacial lake appear red.

 

Melting Glaciers and Climate Change

Glaciers are melting and lakes are
swelling rapidly Example: Lake in Sikkim that was .nonly 2,600 feet (800 meters) in  length in 1988 has doubled to 5,200 feet (1,600 meters). 

Bad News

 increased risks of flooding in nearby valleys especially GLOF.




 इसरो के वैज्ञानिकों ने पूर्वोत्तर हिमालय में एक नई हिमनदी झील के अस्तित्व की सूचना दी है।
 पिछले 20 वर्षों में ली गई उपग्रह छवियों के आधार पर, यह भूरा पानी है। स्थान: समुद्र तल से 5060 मीटर की ऊँचाई पर, ज़ांस्कर घाटी के पास, लद्दाख यह निकटतम गाँव से 11 किलोमीटर दूर है, और लगभग 0.2 वर्ग किलोमीटर के क्षेत्र को कवर करता है।


 झील एक ग्लेशियर द्वारा खिलाया जा रहा है, और
  शोधकर्ताओं का सुझाव है कि यह या तो जलवायु परिवर्तन के कारण होने वाले हिमनदों के पिघलने के कारण बना या विस्तारित हुआ है।


 लाल रंग


 क्षेत्र के स्थानीय भूविज्ञान और लौह-समृद्ध खनिजों के कारण, हेमटिट और गोइथाइट की तरह, जो बर्फ और हिमनद पिघलवाटर के साथ बातचीत करते हैं और बाद में झील में लाल निलंबन जमा करते हैं।

 झील का अनोखा भू-रसायन और  लंबे तरंग दैर्ध्य पर प्रकाश को प्रतिबिंबित करते हैं, जिससे हिमालय की हिमनदी झील लाल दिखाई देती है।


 पिघलते ग्लेशियर और जलवायु परिवर्तन

 ग्लेशियर पिघल रहे हैं और झीलें तेजी से सूजन कर रही हैं उदाहरण: सिक्किम में झील। 1988 में लंबाई में 2,600 फीट (800 मीटर) थी, जो दोगुनी होकर 5,200 फीट (1,600 मीटर) हो गई है।

 बुरी खबर

 पास की घाटियों में विशेष रूप से ग्लॉफ़ में बाढ़ के जोखिम बढ़ गए।

The Ministry of Home Affairs (MHA) has rolled out a "cyber volunteer" programme for "cyber hygiene promotion".The volunteers will be utilised by the State police.The MHA informed the Lok Sabha, about the programme on 9th March 2021 . A group of "cyber crimé volunteers" will be raised through the cyber crime grievance portal. cybercrime.gov.in The volunteers will flag "unlawful content" on the Internet. The Cyber Crime Volunteer Framework has been rolled out as a part of cyber hygiene promotion. Aims to bring together citizens to contribute in the fight against cybercrime in the country and assist State/UT LEAs (law enforcement agencies) in their endeavor to curb cyber crimes. The State/UT Police Authorities will enroll the volunteers and assign them roles, as per their requirement. cyber Crime Volunteers Concept   Indian Cyber Crime Coordination Centre (14C) has been established under Ministry of Home affairs (MHA) to act as a nodal point at ...

Mystery brain disease found in Canada

  WHAT HAS HAPPENED? An unknown brain disease has caused panic in the New Brunswick province of Canada after a string of cases were reported that involved memory loss, hallucinations and muscle atrophy. People living in the province became cognizant of the disease after a memo from the province's public health agency leaked last week, Which asked doctors to look for symptoms relate to Creutzfeldt-Jacob disease (CJD). CJD is a rare brain disease which is caused due to abnormally folded proteins called prions. Creutzfeldt-Jakob (KROITS-felt YAH-kobe) disease (CJD) is a degenerative brain disorder that leads to dementia and, ultimately, death. Creutzfeldt-Jakob disease symptoms can be similar to those of other dementia-like brain disorders, such as Alzheimer's disease. But Creutzfeldt-Jakob disease usually progresses much more rapidly. Transmitted by contact with infected tissue, such as during a transplant or from eating contaminated meat. CAUSES NOT KNOWN FOR CURRENT DISE...

ANDHRA PRADESH STRAIN 15 TIMES MORE VIRULENT

  Experts are saying that a new Andhra Pradesh variant of the SARS-COV-2 virus is at least 15 times more virulent than the earlier ones. May be even stronger than the Indian variants of B. 1.617 and B. 1.618 . Speculation is still on regarding whether it is a new strain or the old N440K. The N440K variant was first discovered by Centre for Cellular and Molecular Biology (CCMB).However, data is still insufficient to confirm anythin. The impact of AP Strain Authorities say that the variant at present which is in circulation in Visakhapatnam is different from what we have seen during the first wave last year. Samples have been sent to CCMB for analysis, in order to find out which strain is in circulation right now.It has been observed that the new variant has shorter incubation period and the progress of the disease is much rapid. In the earlier cases, a patient infected with the virus would take at least a week to reach the hypoxia or dyspnea stage. But in the present context,...
