Researchers discover signalling pathways in wound healing | Bengaluru News

BENGALURU: Using fruit flies as models, researchers have unravelled specific signalling pathways in blood cells that help understand wound healing better. In a new study, they show hydrogen peroxide produced from a wound activates specific signalling pathways in fruit flies’ blood cells, also called hemocytes. The study was carried out by Sveta Chakrabarti, an India Alliance DBT/Wellcome Trust fellow and Sandhya Visweswariah, professor, department of molecular reproduction, development and genetics at IISc. “Our cells sense invading microbes using specific signatures found in them called microbe-associated molecular patterns. Recognising these signatures…

Cher to visit Pakistan to help ‘world’s loneliest elephant’

ISLAMABAD: Iconic singer and actress Cher was set to visit Pakistan on Friday to celebrate the departure of Kaavan, dubbed the “world’s loneliest elephant,” who will soon leave a Pakistani zoo for better conditions after years of lobbying by animal rights groups and activists. Because of security concerns, Cher’s schedule was not made public but “she is on her way,” said Martin Bauer of Four Paws International, a Vienna-based animal welfare group that’s led the charge to save Kaavan. The elephant has languished in the zoo for 35 years, and…

Covid-19 pandemic could be stopped if at least 70% public wore face masks consistently: Study

SINGAPORE: The Covid-19 pandemic could be stopped if at least 70 per cent of the public wore face masks consistently, according to a review of studies which suggests that the type of material used and the duration of mask use play key roles in their effectiveness. The research, published in the journal Physics of Fluids, assessed studies on face masks and reviewed epidemiological reports on whether they reduce the number of people an infected person spreads the pathogen to — the reproduction number of the virus. “The highly efficacious facemask,…

Earth had a minimoon for around 3 years before it drifted away few months ago | World News

Earlier this year, a minimoon was found orbiting Earth by a group of astronomers. The minimoon has now drifted away but astronomers said that more such minimoons will be found orbiting Earth in the future. The minimoon was first spotted by astronomers at the Catalina Sky Survey in Arizona. The astronomers spotted a dim object called 2020 CD3 in February but they were not sure whether it was a a minimoon or an artificial object like a rocket booster. But Grigori Fedorets at Queen’s University Belfast and his team used…

Global warming likely to raise disease risk for animals

NEW YORK: Changes in climate can increase infectious disease risk in animals, with the possibility that these diseases could spread to humans, warn researchers. The study, published in the journal Science, supports a phenomenon known as “thermal mismatch hypothesis,” which is the idea that the greatest risk for infectious disease in cold climate-adapted animals — such as polar bears — occurs as temperatures rise. The hypothesis proposes that smaller organisms like pathogens function across a wider range of temperatures than larger organisms, such as hosts or animals. “Understanding how the…

New therapy for flu may help fight Covid-19: Study

NEW YORK: Scientists have developed a new therapy for influenza virus infections that may also prove effective against many other pathogenic virus infections, including HIV and Covid-19. In an average year, more than two million people in the US are hospitalized with the flu, and 30,000 to 80,000 of them die from it or related complications. According to the study, published in the journal Nature Communications, the research team used a targeted therapy approach against virus infections. “We target all of the antiviral drugs we develop specifically to virus-infected cells,”…

Not just lizards, but these reptiles can also regrow their tails | viral News

Washington: A team of researchers from Arizona State University and the Louisiana Department of Wildlife and Fisheries has found that young alligators have the ability to regrow their tails up to three-quarters of a foot, or 18 per cent of their total body length.  An interdisciplinary team of scientists used advanced imaging techniques combined with demonstrated methods of studying anatomy and tissue organization to examine the structure of these regrown tails. They found that these new tails were complex structures with a central skeleton composed of cartilage surrounded by connective…

Diabetic eye disease associated with five-fold risk of severe Covid-19

LONDON: People with diabetes and eye disease have a five-fold increased risk of requiring intubation when hospitalised with Covid-19, suggest the findings of a new study. The study, published today in Diabetes Research and Clinical Practice by King’s College London, identified for the first time the risk associated with diabetic retinopathy and Covid-19. Diabetic eye disease is a common complication of diabetes and is caused by damage to the small blood vessels in the eye. In 2014, the prevalence of diabetic retinopathy was 54.6% in people with Type 1 diabetes…

Asteroid as big as Burj Khalifa to fly by earth at 56,000mph on November 29 | World News

NEW DELHI: Just a few days before the year 2020 ends, December will be witnessing a flyby of a massive asteroid. An asteroid, said to be 0.51 kilometres in diameter and as tall as the world’s tallest building, the Burj Khalifa of Dubai, is set to pass within 4,302,775 km of Earth. NASA has confirmed that the asteroid named 153201 2000 WO107, will barrel past Earth on Sunday, November 29 and is currently speeding though space at a whopping 56,000mph. It’s terrifyingly huge as its size ranges anywhere between 12,00ft…

UN: Covid-19 lockdowns slashed pollutants, not CO2 levels

GENEVA: A slowdown in industrial activity linked to the coronavirus pandemic has cut emissions of pollutants and heat-trapping greenhouse gases, but hasn’t reduced their record levels in the atmosphere, the United Nations weather agency said on Monday. The World Meteorological Organization pointed to a record-setting surge of carbon dioxide emissions in recent years, but warned that any reduction in levels as a result of a pandemic-related industrial slowdown will take years to materialize. The organization also said this can best be achieved if countries are able to cut their greenhouse…

MMR vaccine may protect against Covid-19, says study

WASHINGTON: The measles-mumps-rubella (MMR) vaccine may provide protection against Covid-19, according to a study that could also explain why children have a much lower case rate and death rate of the disease than adults. The MMR vaccine has been theorised to provide protection against Covid-19, and now the study, published in the journal mBio, provides further proof of this by showing that mumps IgG titers, or levels of IgG antibody, are inversely correlated with severity in recovered Covid-19 patients previously vaccinated with the MMR II vaccine. MMR II contains the…
