Bengaluru on high alert after Gauri Lankesh murder; crime caught on CCTV?

Mangaluru, Jan 31: The Pumpwell flyover, part of the four-laning of Talapady-Kundapura stretch of National Highway 66, was finally inaugurated today.

Work on four-laning NH 66 between Talapady-Kundapur, excluding the Nanthoor-NITK Surathkal stretch, started in September 2010 and Pumpwell (Mahaveera Circle) flyover was a part of the project. Concessionnaire M/s Navayuga Udupi Tollway Pvt., Ltd., failed to execute many flyovers on the stretch within the prescribed time, including Thokkottu and Pumpwell in Mangaluru, Karavali Circle in Udupi, and Shasri Circle in Kundapur.

Thokkottu and Karavali Circle flyovers are complete now while Shastri Circle flyover as well as the four-lane road within Kundapur town are still incomplete. Similarly, a small bridge and portion of the road in Padubidri too is yet to be completed.

District in-charge minister Kota Srinivas Pojjary and MP Nalin Kumar Kateel inaugurated the long-pending Flyover

MLA Vedavayas Kamath, MLA Bharath Shetty were also present on the occasion.

Washington, Jun 30: Researchers in China have discovered a new type of swine flu that is capable of triggering a pandemic, according to a study published Monday in the US science journal PNAS.

Named G4, it is genetically descended from the H1N1 strain that caused a pandemic in 2009.

It possesses "all the essential hallmarks of being highly adapted to infect humans," say the authors, scientists at Chinese universities and China's Center for Disease Control and Prevention.

The researchers then carried out various experiments including on ferrets, which are widely used in flu studies because they experience similar symptoms to humans -- principally fever, coughing and sneezing. 

G4 was observed to be highly infectious, replicating in human cells and causing more serious symptoms in ferrets than other viruses.

Tests also showed that any immunity humans gain from exposure to seasonal flu does not provide protection from G4.

According to blood tests which showed up antibodies created by exposure to the virus, 10.4 percent of swine workers had already been infected.

The tests showed that as many as 4.4 percent of the general population also appeared to have been exposed.

The virus has therefore already passed from animals to humans but there is no evidence yet that it can be passed from human to human -- the scientists' main worry.

"It is of concern that human infection of G4 virus will further human adaptation and increase the risk of a human pandemic," the researchers wrote.

The authors called for urgent measures to monitor people working with pigs.

"The work comes as a salutary reminder that we are constantly at risk of new emergence of zoonotic pathogens and that farmed animals, with which humans have greater contact than with wildlife, may act as the source for important pandemic viruses," said James Wood, head of the department of veterinary medicine at Cambridge University.

A zoonotic infection is caused by a pathogen that has jumped from a non-human animal into a human.

Washington, Jul 1: The United States has approved four coronavirus vaccine candidates for clinical trials, Food and Drug Administration (FDA) head Stephen Hahn told reporters.

"Four vaccines have been approved for moving into clinical trials... and another six are in the pipeline for us to review," Hahn said during a press briefing on Tuesday.

The US Administration launched in May Operation Warp Speed, a joint project of Health and Defense Departments, which aims to deliver 300 million doses of a vaccine for COVID-19 by January 2021.

The country's top pandemics expert Anthony Fauci warned on Tuesday, however, that there is no certainty the United States will be able to develop a vaccine against COVID-19 that works and will be safe.

Data on vaccine effectiveness, he added, may be available in the winter or early next year.
