Sharper images of black hole

According to the new study, scientists have calculated and predicted an intricate internal structure within black hole images caused by extreme gravitational light bending. The study has been published in Science Advances. In this, the lead author Michael Johnson of the Center for Astrophysics Harvard and Smithsonian has described how the swirling ring of photons around a black hole could be the key to unlocking sharp photos. "The image of a black hole actually contains a nested series of rings," Johnson tells IFLScience. "Each successive ring has about the same diameter but becomes increasingly sharper because its light orbited the black hole more times before reaching the observer. With the current EHT image, we’ve caught just a glimpse of the full complexity that should emerge in the image of any black hole." By stacking images of a black hole’s “subrings,” we may one day be able to create a much sharper complete photo of what a black hole looks ...

Does planet 9 exist

Planet Nine is a hypothetical planet in the outer region of the Solar System. Its gravitational effects could explain the unusual clustering of orbits for a group of extreme trans-Neptunian objects, bodies beyond Neptune that orbit the Sun at distances averaging more than 250 times that of the Earth.   Wikipedia It is basically a planet that has not existed till now, it may be there or maybe not it is nor proven to be neither proven not to be.

Corona Vaccine

Here are three of the vaccine that are tested at the time Moderna's mRNA-1273 Moderna Inc. of Cambridge, Massachusetts, has already begun Phase I human testing of its mRNA-1273 at Kaiser Permanente Washington Health Research Institute in Seattle. The test has enrolled 45 healthy adults ages 18 to 55. Phase I will continue over the next six weeks. Phase I of testing looks at the vaccine's safety and whether it is producing an immune response. A later phase of research will look at whether the vaccine is effective in preventing infection. Inovio's INO-4800 Inovio Pharmaceuticals of Plymouth Meeting, Pennsylvania, is using an approach similar to Moderna's to develop a vaccine by modelling off the virus' sequence. Three hours after China published the sequence of the virus online, Inovio developed INO-4800. Inovio uses something called DNA medicine, which is made up of optimized DNA plasmids. Inovio has already developed a vaccine using this...

NASA Identifies Asteroid

NASA Identifies Asteroid 52768 (1998 OR2) as NEO NASA detected recently so massive that it could destroy our entire planet. The space agency’s tracking systems from the Center for Near-Earth Object Studies identified the space object, which has been dubbed 52768 (1998 OR2), speeding toward Earth at a velocity of approximately 31, 320km/h. If the giant asteroid keeps it up like this, it is supposed to approach Earth on April 29. According to scientists, we don’t have reasons to worry at all. They explained how the space object will only make a “close approach” and won’t enter our planet’s orbit. Asteroid 52768 (1998 OR2) measures almost 4.1 kilometres across and is categorized by the Planetary Society as a hazardous space object.

Drosophila

Drosophila is a genus of two-winged flies commonly known as fruit flies that are used in evolutionary and developmental studies. D. melanogaster is an important model organism for the study of genetics and development. Julien Royet, professor of Genetics from University of Marseilles, France, on Thursday said she was very impressed with some of the work happening in India around Drosophila, the common fruit fly which has been a model organism to address basic and applied questions in life sciences. The conference, being held for the first time in India has  given students exposure to showcase their ideas, which they have done with 300 posters on topics like immunity and memory, among others.

Animal that can Survive without Oxygen

A tiny parasite called Henneguya salminicola is the first known multicellular animal that can survive without oxygen. Scientists have just discovered that a jellyfish-like parasite doesn’t have a mitochondrial genome – the first multicellular organism known to have this absence. That means it doesn’t breathe; in fact, it lives its life completely free of oxygen dependency. This discovery isn’t just changing our understanding of how life can work here on Earth – it could also have implications for the search for extraterrestrial life. We know there are adaptations that allow some organisms to thrive in low-oxygen, or hypoxic, conditions. Some single-celled organisms have evolved mitochondria-related organelles for anaerobic metabolism, but the possibility of exclusively anaerobic multicellular organisms has been the subject of some scientific debate. That is until a team of researchers led by Dayana Yahalomi of Tel Aviv University in Israel decided to take another look at a commo...

Detecting Coronavirus

LexaGene’s technology is ideally suited to identify novel pathogens such as coronavirus. Our genetic analyzer can quickly detect new pathogens in just one hour, on-site. Currently, the traditional process requires that samples from sick individuals must be transported to laboratories for manual processing. This is extremely inefficient and introduces a significant time-delay that can have severe consequences for disease spread. Today’s coronavirus outbreak highlights why LexaGene’s technology is needed so desperately. Developing a new diagnostic test to detect this coronavirus is important and has already been done by numerous groups.2  The challenge is bringing these manually performed tests out of the specialized reference laboratories that can take days to return results and instead to the points-of-need, which are the clinics, hospitals, and airports where answers are needed in one hour or less.  Currently, no technology exists that allows for these locations to readily...

WHO declares global coronavirus emergency as death toll hits 213

WHO declares global coronavirus emergency as death toll hits 213 (It is more than 900 now) BEIJING: The United States told its citizens not to travel to China in the first major response to the World Health Organization’s declaration of a global emergency over the spreading coronavirus, as Chinese authorities Friday increased the toll to 213 dead and nearly 10,000 infections. The State Department raised its warning alert to the highest level, telling its citizens “do not travel” to China because of an epidemic that has now spread to more than 20 nations. Hours earlier, the WHO, which has faced criticism for initially downplaying the virus threat, revised its risk assessment after crisis talks in Geneva. “Our greatest concern is the potential for the virus to spread to countries with weaker health systems,” said WHO chief Tedros Adhanom Ghebreyesus. Death toll grows China has taken extreme steps to stop the spread of the virus, including effectively quarantining more than 50...

Coronavirus 2020 Outbreak

Coronavirus  2020 Outbreak A coronavirus is a kind of common virus that causes an infection in your nose, sinuses, or upper throat. Most coronaviruses are not dangerous.  Some types of coronaviruses are serious, though. About 858 people have died from Middle East respiratory syndrome (MERS), which first appeared in 2012 in Saudi Arabia and then in other countries in the Middle East, Africa, Asia, and Europe.     WHO’s standard recommendations for the general public to reduce exposure to and transmission of a range of illnesses are as follows, which include hand and respiratory hygiene, and safe food practices: Frequently clean hands by using alcohol-based hand rub or soap and water; When coughing and sneezing cover mouth and nose with flexed elbow or tissue – throw the tissue away immediately and wash hands; Avoid close contact with anyone who has a fever and cough; If you have a fever, cough and difficulty breathing seek medical care early and...

Gallium Nitride

                                     Gallium Nitride   Gallium Nitride, well this may be the future of electronics. It's a super-effective Semiconductor. Some materials, like copper, are very good at conducting electricity, while materials like glass are not. Semiconductors are about halfway between those two extremes, which makes them really versatile for different products. that means gallium nitride or GaN stands to replace the material, that currently rules the electronics industry silicon. Gallium nitride can pave the way for a whole new generation of miniaturized tech. It can make electronics very-very small. Gallium Nitride the emerging Semiconductor Device Industry And stuff like better solar cells, more efficient power transmission, there's a lot up for grabs. electric cars, which only use gallium nitride, it'll make them very efficient, so they would have a longer rang...

Stirling Engines

                                           Engines Engines  have been powering our world since the Industrial Revolution: first, the dirty coal-powered steam engine , then cleaner and more efficient gasoline   engine ,  and more recently jet engines  in aeroplanes.  The basic concept of an engine—something that exploits the difference between a high temperature and a low one—hasn't changed in a couple of hundred years, although occasionally people do still come up with minor improvements that make the process slightly faster or more efficient. One engine you may have heard a lot about recently is the  Stirling Engine , which is a little bit like a steam engine that uses no steam! Instead, it heats, cools, and recycles the same air or gas over and over again to produce useful power that can drive a machine. Teamed up with solar   pow...
