Quick Heal expects new anti-fraud product to boost its consumer business

Cybersecurity leader Quick Heal Technologies Ltd is optimistic that the launch of the country's first all-in-one fraud prevention solution will boost growth in its consumer business, which currently contributes 62 per cent of its revenue, a company official said on Thursday. The publicly listed company aims to leverage its leadership position to promote its AntiFraud.AI product, targeting individual computer and mobile phone users amid the rising threat of financial fraud. According to the Indian Cybercrime Coordination Centre, Indians lost approximately Rs 1,750 crore to fraudsters in just the first four months of the year, between January and April 2024. "We are very positive about our new anti-fraud cybersecurity product targeted at individual users. This will significantly boost our consumer business in the years to come, which has been facing headwinds," said Quick Heal Managing Director Kailash Katkar, without providing specific growth projections. He explained that before ..

Scientists identify antibody 'SC27' to counter all Covid-19 variants

Researchers have discovered an antibody that could counter all known variants of the coronavirus that causes COVID-19 and also distantly related ones that infect other animals. SARS-CoV-2, the coronavirus causing COVID-19, uses its spike protein to invade and infect another individual, or the host. Antibodies, produced by the host in response, bind to the spike protein to block its action and prevent infection. The researchers, led by those at The University of Texas in Austin, US, isolated the antibody 'SC27' from the plasma donated by four patients. These patients had breakthrough infections, which occur when a vaccinated individual gets infected. The research has been published in the journal Cell Reports Medicine. Over the more than four years since the first case of COVID-19 emerged, SARS-CoV-2 has evolved to acquire certain characteristics which make the virus resistant to vaccines and treatments. The authors said the 'SC27' antibody recognised all these various characterist

Six children die of suspected Chandipura virus in Gujarat since July 10

Six children have died due to suspected Chandipura virus in Gujarat since July 10, with the total number of cases of the infection rising to 12, state Health Minister Rushikesh Patel has said. Samples of the 12 patients have been sent to Pune's National Institute of Virology (NIV) for confirmation, he said on Monday. Chandipura virus causes fever, with symptoms similar to flu, and acute encephalitis (inflammation of the brain). It is transmitted by vectors like mosquitoes, ticks and sand flies. The pathogen is a member of the Vesiculovirus genus of the family Rhabdoviridae. Patel said four of the 12 patients were from Sabarkantha district, three from Aravalli, one each from Mahisagar and Kheda in Gujarat, while two patients were from Rajasthan and one from Madhya Pradesh. They received treatment in Gujarat. "Six deaths due to suspected Chandipura virus have been reported in the state, but only after results of the samples it will be clear whether they were caused by the Chandipura

Boosting anti-viral immune response could slow down aging, says study

Scientists have uncovered details regarding an immune response to a virus present in all human tissues, that kicks in in the elderly and eliminates senescent, or aging, cells in the skin. Senescent cells are those that stop dividing but do not die, accumulating in the body over time, fuelling chronic inflammation and contributing to conditions such as cancer and degenerative disorders. Eliminating senescent cells from aging tissues has been found to restore tissue balance in mice, leading to an increased healthy lifespan. When a team of scientists, led by Massachusetts General Hospital (MGH), US, found that the number of senescent cells in samples from old individuals did not increase as the individuals got older, they realised that there is some mechanism kicking in to keep the aging in check. The scientists have described their findings in the journal Cell. Experiments have proved that in the elderly, certain immune cells called killer CD4+ T cells keep senescent cells from ...

Ancient viral DNA in human genome protects against infections: Research

According to new research, viral DNA embedded in human genomes from ancient infections acts as antivirals, protecting human cells from certain modern viruses.The paper "Evolution and Antiviral Activity of a Human Protein of Retroviral Origin," published in the journal Science, demonstrates the effect in principle.Previous research has shown that endogenous retroviruses, fragments of ancient viral DNA found in the genomes of mice, chickens, cats, and sheep, provide immunity against modern viruses that originate outside the body by preventing them from entering host cells. Despite the fact that this research was done on human cells in culture, it shows that endogenous retroviruses have an antiviral effect on humans.The study is significant because it could discover a pool of natural antiviral proteins that could lead to treatments without autoimmune side effects. The research suggests the existence of a genome defence system that has yet to be identified but could be quite ...
