Artificial Intelligence predicts which planetary systems will survive

WASHINGTON DC: Rejecting the large range of unstable possibilities, all the configurations that would lead to collisions would leave behind a sharper view of planetary systems around other stars, but it’s not as easy as it sounds. “Separating the stable from the unstable configurations turns out to be a fascinating and brutally hard problem,” said Daniel Tamayo, a NASA Hubble Fellowship Program Sagan Fellow in astrophysical sciences at Princeton. To make sure a planetary system is stable, astronomers need to calculate the motions of multiple interacting planets over billions of…

Understanding bat immune system may help identify new Covid-19 drug targets, scientists say

NEW YORK: The capacity of bats to tolerate viruses such as the novel coronavirus may stem from their ability to control inflammation, according to a review of studies which says understanding the immune system of the flying mammals can provide new drug targets for human therapies against Covid-19. Researchers, including those from the University of Rochester in the US, said while bats are the ancestral hosts to many deadly viruses affecting humans such as Ebola, rabies, and the novel coronavirus, SARS-CoV-2, the flying mammals themselves tolerate these pathogens without ill…

NASA partners SETI Institute on planetary protection

WASHINGTON: NASA has awarded the SETI Institute in Mountain View, California, a $4.7 million contract to support current and future planetary protection missions to ensure compliance with planetary protection standards. The five-year contract began on July 1, NASA said on Friday. Some of the upcoming NASA science missions that will be supported by this contract include the Mars 2020 and Europa Clipper missions, and preparations for NASA’s Mars Sample Return mission. In addition, future human spaceflight exploration under NASA’s Artemis programme, such as the Gateway lunar orbital outpost, the Human…

Zimbabwe bird sanctuary has 400 species, not enough tourists

HARARE, ZIMBABWE: A fish eagle swoops over the water to grab a fish in its talons and then flies to its nest. Nearby are a martial eagle, a black eagle, an Egyptian vulture and hundreds of other birds. With an estimated 400 species of birds on an idyllic spot on Zimbabwe’s Lake Chivero, about 40 kilometers (25 miles) south of Harare, the Kuimba Shiri bird sanctuary has been drawing tourists for more than 15 years. The southern African country’s only bird park has survived tumultuous times, including violent land invasions…

Brazil Amazon deforestation up in June, set for worst year in over a decade

BRASILIA: Deforestation in Brazil‘s Amazon rose for the 14th consecutive month in June, preliminary government data on Friday showed, heaping further pressure on President Jair Bolsonaro who is under fire for worsening destruction of the rainforest on his watch. Destruction rose 10.7% percent for the month, compared to June 2019, according to national space research agency Inpe. In the first six months of the year, deforestation is now up 25% to 3,066 square kilometers (1,184 square miles), agency data showed. “The pressure is increasing,” said Mariana Napolitano, advocacy group WWF-Brasil’s…

How good gut bacteria helps reduce heart disease risk

NEW YORK: Researchers have discovered that one of the good bacteria found in the human gut has the potential to reduce the risk of heart disease. The bacteria’s activity in the intestines reduces the production of a chemical that has been linked to the development of clogged arteries, the study, published in the Journal of Biological Chemistry, said. “The organism we studied affects health by preventing a problematic compound from becoming a worse one,” said study researcher Joseph Krzycki from the Ohio State University in the US. For the findings,…

Scientists focus on how immune system T cells fight coronavirus in absence of antibodies

As scientists question whether the presence, or absence, of antibodies to the novel coronavirus can reliably determine immunity, some are looking to a different component of the immune system, known as T cells, for their role in protecting people in the pandemic. Recent studies show that some recovered patients who tested negative for coronavirus antibodies did develop T cells in response to their Covid-19 infection. While the studies are small and have yet to be reviewed by outside experts, some scientists now say that people who experience a mild illness,…

Huge UFO, 25 times the size of Earth spotted near Sun, claims UFO hunting enthusiast Scott C Waring | Space News

New Delhi: UFO hunting enthusiast Scott C Waring has claimed that he has spotted evidence of a huge UFO, 25 times the size of the Earth, near the Sun. “I caught a giant black orb exiting our sun on SOHO images today. The images are actually from June 27, but are still seen as current for some unknown reason. The black sphere is over 25X the size of the earth and sits there for a few hours before it shoots away,” the self-proclaimed UFO hunter wrote in the blog ET…

Air pollution increases risk of Covid-19, deaths: Study

Bengaluru: Air pollution in Bengaluru is linked to the loss of an estimated 6,300 lives in the first half of 2020 and 3.7 per cent decline in the city’s annual GDP despite strictly enforcing Covid-19 related lockdown, a study has revealed. According to a new online tool by IQAir AirVisual and Greenpeace-Southeast Asia, research shows that long-term air pollution exposure increases the risk of severe Covid-19 infections and death. “Air pollution in Bengaluru is linked to the loss of an estimated 6,300 lives in the first half of 2020 despite…

Is it safe to visit the dentist during the pandemic?

WASHINGTON: Is it safe to visit the dentist during the Covid-19 pandemic? Dentists can’t eliminate all risk, but they are taking steps to minimize the chances of spreading the coronavirus. You’ll likely notice changes as soon as you enter the office. Many dentists have removed magazines from waiting rooms, for example, as well as some chairs to encourage social distancing. They also are spacing out appointments to avoid crowding their offices. You may be asked to arrive for your appointment with a facial covering and to wait in your car…
