Scientist discover first new HIV strain in 19 years.

For the first time in nearly two decades, a team of scientists has discovered a new strain of HIV. HIV has several subtypes or strains and they mutate over time. HIV subtypes are classified into different groups based on the latest guidelines (2000). The HIV strain that causes a global pandemic is from group M.

The newly discovered strain is also from the HIV-1 Group M, subtype L.1 and it is the first HIV subtypes from group M identified since guidelines for classifying subtypes were established in 2000. It was reported by Abbott Laboratories, which conducted the research with the University of Missouri.

Is it dangerous for us?

We don't need to panic because not a lot of people are infected with this strain and there is medicine available to treat against this strain. There's no reason to panic or even to worry about it a little bit," Fauci, director of US National institute of allergy and infectious diseases told CNN. "Not a lot of people are infected with this. This is an outlier."

The findings were published Nov. 7 in the Journal of Acquired Immune Deficiency Syndromes.

What next?

This could help us understand how HIV evolves. With a proper understanding of how it evolves, we could hopefully find a way to treat AIDS in the future.

Story of Kary Mullis, PCR inventor

'Sometimes a great idea comes to you when you are not looking for it' 'Science is subject to arbitrary fashion' 'Science grows like a weed every year' Kary Mullis at TED talk. Kary Mullis, inventor of PCR was born on 28 December 1944 in North Carolina, USA. His parents grew up in the foothills of Blue ridge Mountains. And they live near their grandfather’s farm. Kary Mullis was an eight-year-old boy when Watson and Crick published the structure of DNA in 1953. By the time Watson and Crick were awarded Nobel prize, Kary was still busy designing rockets in Georgia Institute of Technology. He was not interested in studying DNA at all. By the time he left Georgia Tech, biologists had already solved the genetic code. It was during his six years at UC, Berkley as a Ph.D. student that changes his mind. After six years at Berkley with a Ph.D., he headed to Kansas to become a writer. He quickly found out he was too young to be a writer and was poor...

RNA editing, CRISPR-Cas 13 provides herd immunity against dsDNA phage.

CRISPR-cas13: the only RNA editing CRISPR till date. CRISPR RNA targeting CRISPR-cas13 provides immunity against dsDNA phage without cutting the genome, unlike the other 5 types which work by cutting the genome. CRISPR-Cas13 works differently. It provides herd immunity to the bacteria. CRISPR-Cas13 There are six types of CRISPR in literature till now (1-6). CRISPR Cas VI is the only one that cuts the RNA. It cuts the RNA transcript complementary to the target sequence of the mRNA . After cutting the complementary RNA, it starts cutting all other mRNAs of the phage which Scientists called Collateral damage. This is the phenomena that provide Herd immunity. 3D structure of CRIPSR-Cas References: Cas13 Helps Bacteria Play Dead when the Enemy Strikes.

Biodegradable burial pod turns your body into a tree.

Bretzel and Citelli with Capsula Mundi Model. Whenever a person dies, it is a burden for the family emotionally and financially. We spend thousands of dollars in funerals paying for the casket, flowers, and monuments. Environmentally, those caskets and monuments left behind an enormous carbon footprint. Recently, many people have begun to embrace the idea of green burials. People are environmentally more aware and there is a shift from cremation and the use of wood, the synthetic cushioning and the metals generally used in traditional coffins to green burial. Green burial is a method of burying the body in a wooden coffin without a concrete burial vault. The body along with the wooden coffin is degraded easily by the bacteria in the soil. This type of burial allows the graveyard to return to nature. Nearly 54 percent of Americans are considering green burial and 74 percent of cemeteries are reporting an increased demand for g...
