NHAI’s First ‘Sustainability Report’

 

NHAI’s Sustainability Report is not a mandated requirement as per SEBI guidelines, but this has been taken as a voluntary initiative to demonstrate its sustainability credentials and is prepared as per the Global Reporting Initiative (GRI) reporting guidelines.

 

We will take important information from the report:

     

NHAI has planted more than 274 lakh plants on national highways in post adoption of Green Highway Policy from years of 2016-17.

Global Digital Health Certification Network

 

News:

WHO’s Global Digital Health Certification Network is an open-source platform, built on robust & transparent standards that establishes the first building block of digital public health infrastructure for developing a wide range of digital products for strengthening pandemic preparedness and to deliver better health for all.

One of the key tools used by many Member States in reopening economies during the COVID-19 pandemic has been digital COVID-19 test and vaccine certificates.

Learning from the COVID-19 pandemic response, there is a recognition of an existing gap and continued need for a global mechanism that can support bilateral verification of the provenance (place of origin) of health documents for pandemic preparedness and continuity of care.

The GDHCN can be used as an infrastructural building block to support, for example, the digitisation of the International Certificate of Vaccination, verification of prescriptions across borders, the International Patient Summary, verification of vaccination certificates within and across borders, and certification of public health professionals (through WHO Academy).

World's oldest-known burial site found in South Africa

 

Palaeontologists found the oldest known burial site in the world, containing remains of a small-brained distant relative of humans previously thought incapable of complex behaviour.

Researchers said they discovered several specimens of Homo naledi -- a tree-climbing, Stone Age hominid -- buried about 30 metres (100 feet) underground in a cave system within the Cradle of Humankind, a UNESCO world heritage site near Johannesburg.

These are the most ancient interments yet recorded in the hominin record, earlier than evidence of Homo sapiens interments by at least 100,000 years.

The findings challenge the current understanding of human evolution, as it is normally held that the development of bigger brains allowed for the performing of complex, "meaning-making" activities such as burying the dead.

The oldest burials previously unearthed, found in the Middle East and Africa, contained the remains of Homo sapiens—and were around 100,000 years old.

First Evidence for Rare Decay of Higgs Boson

 

First learn about Hoggs Boson. Then news is important.

The Higgs boson is a type of boson, a force-carrying subatomic particle. It carries the force that a particle experiences when it moves through an energy field, called the Higgs field, that is believed to be present throughout the universe. For example, when an electron interacts with the Higgs field, the effects it experiences are said to be due to its interaction with Higgs bosons.

The stronger a particle’s interaction with the Higgs boson, the more mass it has. This is why electrons have a certain mass, protons have more of it, and neutrons have just a little bit more than protons, and so on. A Higgs boson can also interact with another Higgs boson: this is how we know that its mass is greater than that of protons or neutrons.

 

Now we will see news:

Last week, researchers reported that they had detected a Higgs boson decaying into a Z boson particle and a photon. This is a very rare decay process that tells us important things about the Higgs boson as well as about our universe.

So, a question should arise: how did a Higgs boson decay to a Z boson and a photon if it doesn’t interact with photons? THIS IS WHAT IT “reflecting the rarity of the decay pathway”.

Now from here don’t go in detail. No need for UPSC aspirant.
