Look What Mummy’s DNA Analysis Revealed!

Toronto: The DNA analysis of the remains of a 16th century mummy has confirmed that the complex Hepatitis B virus (HBV) has existed in humans for centuries, researchers say.

HBV is a deadly viral infection that attacks the liver, can cause both acute and chronic disease and kills nearly one million people every year. The findings are based on DNA extracted from the mummified remains of a small child buried in the Basilica of Saint Domenico Maggiore in Naples, Italy.

Previous analysis of the 450-year old mummified remains -- which did not include DNA testing -- suggested that the child was infected with Variola virus, or smallpox.

Using advanced sequencing techniques, researchers now suggest that the child was actually infected by HBV, throwing light on the evolution of the disease. "These data emphasise the importance of molecular approaches to help identify the presence of key pathogens in the past, enabling us to better constrain the time they may have infected humans," said lead investigator Hendrik Poinar, an evolutionary geneticist at McMaster University in Hamilton, Canada.

While viruses often evolve very rapidly, this ancient strain of HBV has changed little over the last 450 years and that the evolution of this virus is complex, the researchers noted, in the paper published in the journal PLOS Pathogens.

Over 350 million people living today have chronic HBV infections while approximately one-third of the global population has been infected at some point in their lives, emphasising the importance of studying ancient viruses.

"The more we understand about the behaviour of past pandemics and outbreaks, the greater our understanding of how modern pathogens might work and spread, and this information will ultimately help in their control," Poinar stated.

Delhi Tests Air Raid Sirens as Part of Mock Drill

In an attempt to educate and make people aware about the consequences of war amid Pakistan's continuous firing in the border states, the Delhi government did a mock drill to test air raid sirens installed at the Public Works Department (PWD) at ITO and asked people to not react out of panic. 

District Magistrate (Central) G. Sudhakar also urged people to remain calm and not be alarmed when they hear the sirens.

At least twice, sirens sounded during the drill, which started at 3 pm.

PWD Minister Parvesh Verma said 40-50 more such sirens will be installed across the national capital, each of which will cover an area of 8 km.

India Pakistan War Live! Kashmir Loses Electricity in Various Parts

Since the early hours of Saturday morning (10th May), Srinagar has been rocked with multiple explosions, and now electricity is taken off in various places across Kashmir. The reason for this is yet to be determined, as reports indicate multiple places in Kashmir have lost power. The Indian Army released a statement after the press briefing, where they mentioned that they have attacked and neutralized multiple terrorist launchpads in a coordinated fire assault, razing them to cinders.
