Astronomers have found a planet like Earth orbiting a star like the sun

NASA’s Transiting Exoplanet Survey Satellite (TESS) has discovered its first Earth-size planet in its star’s habitable zone, the range of distances where conditions may be just right to allow the presence of liquid water on the surface. Scientists confirmed the find, called TOI 700 d, using NASA’s Spitzer Space Telescope and have modeled the planet’s potential environments to help inform future observations.
TOI 700 d is one of only a few Earth-size planets discovered in a star's habitable zone so far. Others include several planets in the TRAPPIST-1 system and other worlds discovered by NASA’s Kepler Space Telescope.
“TESS was designed and launched specifically to find Earth-sized planets orbiting nearby stars,” said Paul Hertz, astrophysics division director at NASA Headquarters in Washington. “Planets around nearby stars are easiest to follow-up with larger telescopes in space and on Earth. Discovering TOI 700 d is a key science finding for TESS. Confirming the planet’s size and habitable zone status with Spitzer is another win for Spitzer as it approaches the end of science operations this January."

Earth’s magnetic field is mysteriously weakening, causing satellites and spacecraft to malfunction

The Earth's magnetic field is weakening between Africa and South America, causing issues for satellites and space craft.
Scientists studying the phenomenon observed that an area known as the South Atlantic Anomaly has grown considerably in recent years, though the reason for it is not entirely clear.
Using data gathered by the European Space Agency's (ESA) Swarm constellation of satellites, researchers noted that the area of the anomaly dropped in strength by more than 8 per cent between 1970 and 2020.

"The new, eastern minimum of the South Atlantic Anomaly has appeared over the last decade and in recent years is developing vigorously," said J├╝rgen Matzka, from the German Research Centre for Geosciences.
"We are very lucky to have the Swarm satellites in orbit to investigate the development of the South Atlantic Anomaly. The challenge now is to understand the processes in Earth's core driving theses changes."

Enlisting Monoclonal Antibodies in the Fight Against COVID-19

We now know that the immune system of nearly everyone who recovers from COVID-19 produces antibodies against SARS-CoV-2, the novel coronavirus that causes this easily transmitted respiratory disease [1]. The presence of such antibodies has spurred hope that people exposed to SARS-CoV-2 may be protected, at least for a time, from getting COVID-19 again. But, in this post, I want to examine another potential use of antibodies: their promise for being developed as therapeutics for people who are sick with COVID-19.
In a recent paper in the journal Science, researchers used blood drawn from a COVID-19 survivor to identify a pair of previously unknown antibodies that specifically block SARS-CoV-2 from attaching to human cells [2]. Because each antibody locks onto a slightly different place on SARS-CoV-2, the vision is to use these antibodies in combination to block the virus from entering cells, thereby curbing COVID-19’s destructive spread throughout the lungs and other parts of the body.

Black hole found 1,000 light years from Earth

Astronomers say they have discovered a black hole on our doorstep, just 1,000 light years from Earth.
It was found in a system called HR 6819, in the constellation Telescopium.
The system appears through a telescope as a single bright star, but telltale signs in the light emitted have previously revealed there to be two stars present.
Now experts say they have further analysed the data to discover there is another body within the system: a black hole with a mass over four times that of our sun, and the closest to Earth found so far.

Seeking the essence of consciousness in the human brain: spirituality or science?

Are you ready for this? There’s an exciting debate underway among respected scientists over a theory more fascinating than Einstein’s about relativity. This new, science-based theory suggests that our consciousness, even our personalities, do not die when we do, have been around far longer than we have, and continue indefinitely.

So let’s take a quick look at how some distinguished scientists have come to acknowledge our very soul, and how the brain in each of us has an identifiable, measurably spiritual nature. And we can start with something as celebrated as things and places said to be “haunted.”

Swiss cantons 'halt' use of new 5G masts due to health concerns

Some Swiss regions have suspended the use of new mobile sites constructed for 5G due to health concerns.
The country is one of the most advanced 5G nations in Europe, with Swisscom and Sunrise among the first to launch next-generation networks. Speeds and coverage outpace other nations in the region and the government itself is interested in using 5G for applications like smart farming.
However, Switzerland is also home to a vocal community of anti-5G campaigners. Protests have taken place in major cities while rural mayors have declared their desire to remain ‘5G-free zones’.
