The new corona variant has 23 mutations in all, which is unusually huge !

Shruti Paniwala — Wed, 23 Dec 2020 03:50:50 -0600

The new SARS-CoV-2 version, B.1.1.7, which was first seen in the third week of September in Kent and Greater London, has since spread to other locations in the UK. According to the COVID-19 Genomics UK Consortium (COG-UK Consortium) that analysed the genome data of the virus and identified the variant, the new variant has been spreading "rapidly" over the last four weeks and has now been detected in other locations in the UK, suggesting further spread of the variant in the region.

According to a preliminary report posted on December 19 by the COG-UK Consortium scientists, as of December 15, 1,623 variant genomes have been sequenced. In a December 21 tweet, COG-UK Consortium said that it added 2,963 more genome sequences of SARS-CoV-2, of which 942 (32%) belong to the new variant. The Consortium intends to sequence 20,000 more SARS-CoV-2 genomes in the next two weeks to further ascertain the spread of the variant.

There is no clear proof, at least not yet, that it does cause severe pandemic. But there is a justification for seriously taking the possibility. Another coronavirus lineage in South Africa has acquired one specific mutation that is also present in B.1.1.7. This variant is increasingly spreading across South Africa's coastal regions. And doctors have observed in preliminary research that individuals infected with this variant bear a higher viral load-a higher concentration of the virus in their upper respiratory tract. In many viral diseases, this is associated with more severe symptoms.

Stephen Friend: The hunt for "unexpected genetic heroes"

Sat, 31 May 2014 14:31:47 -0500

What can we learn from people with the genetics to get sick — who don't? With most inherited diseases, only some family members will develop the disease, while others who carry the same genetic risks dodge it. Stephen Friend suggests we start studying those family members who stay healthy. Hear about the Resilience Project, a massive effort to collect genetic materials that may help decode inherited disorders.

Fourth Branch of Life

Jitendra Narayan — Mon, 09 Sep 2013 21:48:37 -0500

Scientist have found the biggest viruses known, pandoraviruses which opened up entirely /completely... new questions questions and raise objections to in science. It even suggesting a fourth domain of life.

The new visrus are about one micron—a thousandth of a millimeter—in length, the newfound genus Pandoravirus dwarfs other viruses, which range in size from about 50 nanometers up to 100 nanometers. A genus is a taxonomic ranking between species and family.

Mosquito species known for transmitting the Dengue virus

BioStar — Wed, 03 Apr 2024 00:05:51 -0500

Here is a list of mosquito species known for transmitting the Dengue virus along with essential and applied information about each species:

1. Aedes aegypti:
- Geographical Distribution: Found in tropical and subtropical regions worldwide.
- Biting Behavior: Daytime biter, prefers feeding indoors, often around human dwellings.
- Role in Dengue Transmission: Primary vector responsible for transmitting Dengue virus to humans.

2. Aedes albopictus (Asian tiger mosquito):
- Geographical Distribution: Found in tropical, subtropical, and temperate regions worldwide.
- Biting Behavior: Daytime biter, feeds both indoors and outdoors, aggressive feeder.
- Role in Dengue Transmission: Secondary vector, can transmit Dengue virus to humans.

3. Aedes polynesiensis:
- Geographical Distribution: Found in Pacific Islands and coastal regions.
- Biting Behavior: Daytime biter, prefers feeding outdoors, often near coastal areas.
- Role in Dengue Transmission: Vector of Dengue virus in specific geographic regions.

4. Aedes scutellaris:
- Geographical Distribution: Found in Southeast Asia, Pacific Islands, and coastal regions.
- Biting Behavior: Daytime feeder, active in shaded areas, prefers outdoor environments.
- Role in Dengue Transmission: Vector of Dengue virus, particularly in coastal areas.

5. Aedes africanus:
- Geographical Distribution: Found in parts of Africa, including forested areas.
- Biting Behavior: Daytime feeder, prefers shaded areas, bites humans and other animals.
- Role in Dengue Transmission: Vector of Dengue virus in African regions.

Understanding the geographical distribution and biting behavior of these mosquito species is crucial for implementing effective control and prevention strategies to reduce Dengue virus transmission.
