Getting weary of masks and sanitisers? We bring good news! One of the world's top contenders for an effective coronavirus vaccine was recently able to trigger immune responses among the old and young alike. Developed by the University of Oxford, the vaccine was able to trigger a response among both the young, as well as the elderly. The candidate vaccine produced lower adverse responses among the aged, the company helping in its manufacturing - AstraZeneca Plc announced on Monday. The COVID-19 pandemic has killed more than 1.15 people across the world, shutting down economies globally, and crippling life for billions alike.

"The results further build the body of evidence for the safety and immunogenicity of AZD1222," the spokesman said. AZD1222 is the technical name of the vaccine. The vaccine might become the first to receive regulatory approval, alongside vaccine candidates by Pfizer and BioNTech. This is especially important in terms of the response produced among the elderly, for that age group falls under the most vulnerable category, and the immune system is weakened over time. Additionally, the old people are also at the highest risk of dying from the virus. Work on the Oxford vaccine began in January 2020. Commonly referred to as AZD1222 or ChAdOx1 nCoV-19, the vaccine is based on the "viral vector" imprint, and is derived from a weakened version of the common cold virus.

This modification is done in the spike protein, from where the COVID-19 virus gains entry into human cells. Scientists hope that the human body will attack COVID-19 if seen again. According to the Financial Times, the details of the findings will be published in a clinical journal shortly. In anticipation of successful responses, AstraZeneca has signed multiple supply and manufacturing deals with companies and governments around the globe. The company is preparing to divulge details of the late-stage clinical trial. The company announced on Friday that the US trials of the vaccine resumed after receiving approval from US regulators. According to The Sun, a hospital in London will receive the first batches of the vaccine, which will be administered on its staff.
Asteroid alert: Space rock to zip past Earth today, will be closer than geostationary satellites - WION
US space agency NASA has said that an asteroid will fly past the Earth on Thursday which would be just 28,254 km from the Earths surface.
US space agency NASA has said that an asteroid will fly past the Earth on Thursday which would be just 28,254 km from the Earth's surface. Watch: The asteroid would be speeding at around 27, 900 km per hour, the space agency said. Also Read: Asteroid heading towards Earth a day before US elections The asteroid named 2020 SW is around 15 to 30 feet wide, the NASA scientists said, which is roughly the size of a small bus. The rock which was discovered just last week will continue on its journey around the Sun and wouldn't return to the Earth's atmosphere before 2041, scientists said. According to EarthSky, the asteroid is so small that the Earth's gravity is expected to change the rock's course when it goes past the Earth. However, it will be a close call as it will pass just 7 per cent of the Moons distance and will be passing closer than geostationary satellites which are placed 35,888 km from our planets surface. However, EarthSky said that "there is no risk of impact." The rocks is expected to be at its closet when it passes over Australia or New Zealand. However, there is bad news for stargazers as it won't be visible through the naked eye but can be viewed through a 6 or 8-inch diameter telescope and is likely to increase in brightness as it approaches the Earth. "The space rock is currently in the constellation of Pegasus the Flying Horse, and will then move to the constellation of Pisces the Fish," EarthSky said.
Children need extensive testing to identify ‘silently shedding’ COVID-19: Study - WION

New research suggests that children can shed SARS-CoV-2, the virus that causes COVID-19, even if they never develop symptoms or for long after symptoms have cleared. The study, published in the journal JAMA Pediatrics, provides important insight on the role children might play in the spread of coronavirus as communities continue to develop public health strategies to reign in this disease. The study that sparked this commentary focused on 91 pediatric patients followed at 22 hospitals throughout South Korea. Also read: Children face greater risk from coronavirus than previously expected, says study "Unlike in the American health system, those who test positive for Covid-19 in South Korea stay at the hospital until they clear their infections even if they aren`t symptomatic," said study researcher Roberta L. DeBiasi from Children`s National Hospital in the US. The patients here were identified for testing through contact tracing or developing symptoms. Also read: Coronavirus could be tied to a rare but serious illness in children About 22 per cent never developed symptoms, 20 per cent were initially asymptomatic but developed symptoms later, and 58 per cent were symptomatic at their initial test. Over the course of the study, the hospitals where these children stayed continued to test them every three days on average, providing a picture of how long viral shedding continues over time. The study's findings show that the duration of symptoms varied widely, from three days to nearly three weeks. There was also a significant study in how long children continued to shed virus and could be potentially infectious. While the virus was detectable for an average of about two-and-a-half weeks in the entire group, a significant portion of the children, about a fifth of the asymptomatic patients and about half of the symptomatic ones, were still shedding virus at the three-week mark. The researchers wrote that the study makes several important points that add to the knowledge base about Covid-19 in children. One of these is a large number of asymptomatic patients, about a fifth of the group followed in this study. Another is that children, a group widely thought to develop a mostly mild disease that quickly passes, can retain symptoms for weeks. A third and important point, they said, is the duration of viral shedding. Even asymptomatic children continued to shed virus for a long time after initial testing, making them potential key vectors. Recently, a study published in The BMJ journal, revealed that children and young people have less severe COVID-19 than adults and death is exceptionally rare. Earlier, another research published this month in the Journal of Pediatrics, found that children play a larger role in the community spread of the Covid-19.
Asteroid bigger than London Eye approaching close to Earth, warns NASA - WION
The famous UK landmark is 443 feet high, and the space rock is larger than the London Eye by as much as 50 per cent.
A huge asteroid believed to be more than one and half times the size of the London Eye is approaching Earth, space agency NASA has warned. The famous UK landmark is 443 feet high, and the space rock is larger than the London Eye by as much as 50 per cent. The space agency has given the asteroid the name Asteroid 2020ND, and have branded the asteroid "potentially hazardous". The rock will make its closest approach to Earth on July 24, reports Birmingham Live. NASA has warned it will come within just 0.034 astronomical units (AU) of our planet. The space agency said: "Potentially Hazardous Asteroids (PHAs) are currently defined based on parameters that measure the asteroids potential to make threatening close approaches to the Earth. Also read | Five asteroids head towards Earth; one the size of stadium "Specifically, all asteroids with a minimum orbit intersection distance (MOID) of 0.05 AYU or less are considered PHAs." An astronomical unit is equal to about 150 million kilometres or roughly the distance from the Earth to the Sun. NASA said on its Jet Propulsion Laboratory (JPL) website: "The scientific interest in comets and asteroids is due largely to their status as the relatively unchanged remnant debris from the solar system formation process some 4.6 billion years ago. "The giant outer planets (Jupiter, Saturn, Uranus, and Neptune) formed from an agglomeration of billions of comets and the left over bits and pieces from this formation process are the comets we see today. IN PICS | You can see these 5 planets in the night skies all week long! "Likewise, todays asteroids are the bits and pieces left over from the initial agglomeration of the inner planets that include Mercury, Venus, Earth, and Mars."
