A ghostly subatomic particle can be resurrected from the catastrophic encounter of a star with a black hole. Made by the IceCube detector in Antarctica, the neutrino carried 200 trillion electron volts, roughly 30 times more energy than the protons accelerated by the Large Hadron Collider. The scientists compared the detection of neutrinos to the flashes of light in the sky caused by a black hole slicing through a star.

Astronomers discover a giant

The probability that a neutrino and flare will match is only 0.2 percent. If the search continues, this will be only the second time a high-energy neutrino has been traced to its origin, and the first direct evidence that cutting a star can accelerate a neutrino to higher energies.

North America

There has been a long-standing debate about when humans first traveled to and from the Americas. A group of researchers reported that people arrived in North America 15,000 years earlier than is generally thought.

Archaeologists

Based on the discovery of some 33,000-year-old stone tools found in Mexico. However, some archaeologists suspect that the artifacts are also stone tools and say they are naturally broken rocks.

Research group

Another research group reported that indigenous South Americans crossed thousands of miles of open sea and reached eastern Polynesia more than 800 years ago, with settlers from Asia initially colonizing the islands.

South Americans

This conclusion is based on genetic evidence suggesting that fearless South Americans coexisted with ancient Polynesians. But some anthropologists wonder if early South American groups had the marine tools or skills necessary for the voyage.

The most important news - For the first time in history, a person's immune system fought HIV and won. The scientists analyzed billions of cells from two people living with HIV who do not need medication to keep the virus under control. What the team found was surprising: One person did not have a working copy of HIV in any of her cells, while the other had only one working copy.

What's more, that copy was imprisoned in tightly wound DNA. Finally the first superconductor is found at room temperature. Up to 15 ° C, a substance composed of carbon, sulfur and hydrogen can conduct electricity without resistance. While the room-temperature superconductor only works at high pressures, this discovery brings scientists closer to achieving a more energy-efficient future.

Astronomers have finally found the edge of the Milky Way. Computer simulations and observations of nearby galaxies showed that the Milky Way spans 1.9 million light years. Measurements can help determine how massive the Milky Way is and how many galaxies actually orbit it. More 'Killer Hornets' are coming out..this is what you need to know. The invasion of the Asian giant hornet in North America can be a problem for bees.

But the threat to people from the world's largest hornet species is small. A star orbiting the galaxy's black hole validates Einstein The anomalous orbit of a star around the supermassive black hole at the center of the Milky Way confirms Albert Einstein's general theory of relativity. Instead of traversing a single ellipsoid, the star's orbit rotates over time, the result of the black hole's space-time warp.

After the Notre Dame fire, scientists can take a look at the origins of the cathedral. The April 2019 fire at Notre Dame Cathedral in Paris provided scientists with an opportunity to delve into the cathedral’s history and study the building’s materials, learning more about climate change.

New fleets of private satellites are taking off from the night sky. SpaceX and other private companies plan to launch thousands of Internet satellites into Earth orbit. Hundreds of satellites already in outer space obstruct the view of ground-based telescopes and interfere with astronomers' research.

It's time to stop debating how to teach children and follow the evidence. Research has identified the most effective ways to teach children to read. Those findings may help resolve a long-standing debate that pits phonetics against methods that emphasize understanding the meaning of words.

To fight discrimination, the US Census needs a separate racial question. The United States Census has not accurately listed some minority groups. As a result, some sociologists are asking more nuanced census questions that better reflect how respondents view themselves, as well as how society views them, a clear metric for measuring discrimination.

Individual actions around housing, transportation and food can create ripple effects in society to help mitigate the effects of climate change. But to make the most of an impact, people must tailor their efforts to their circumstances. Science News has reported it since the beginning of the COVID-19 pandemic, but none of those stories were on our 2020 most read list. That’s because we think the coverage is unique.
