Scientists have uncovered a near perfectly preserved ancient “wooly rhino” that is between 20,000 and 50,000 years old.

The near perfectly preserved woolly rhino was discovered in August 2020 in permafrost deposits by the river Tirekhtyakh in the Republic of Sakha in Arctic Yakutia. It is the best preserved juvenile woolly rhino every found in Yakutia. The ancient rhino has much of its body intact including internal organs, teeth, part of the intestines, fat, tissues, and hair. The cold permafrost kept the animal's body preserved for thousands of years. "The young rhino was between three and four years old and lived separately from its mother when it died, most likely by drowning." The animal's thick fur hints the animal died in the summertime.

Here’s what a solar eclipse looks like from space as it travels across the planet.

December 14, 2020 solar eclipse over South America If you were in the southern tip of South America on December 14, 2020, you were in for a special treat - the only solar eclipse of 2020. But thanks to the National Oceanic and Atmospheric Administration (NOAA), we are in for a treat too. NOAA's satellite captured the eclipse as it moved across the planet. In the animated gif above, you can see the moon's shadow sweep across the African continent, blocking out the sun. NOAA explained: "People in areas where the outer part of the moon's shadow falls, called the penumbra, see a partial solar eclipse. For today's eclipse, that included much of South America as well as a small portion of Africa's southwest coast. If the sun

How does the COVID-19 vaccine work? How does it differ from the flu vaccine? Is it safe?

Today the first person in the United States received a COVID-19 vaccination, a vaccine intended to prevent the coronavirus infection. This vaccine is a light at the end of the tunnel, a hope that the pandemic can be stopped. It's practically a miracle that it was developed so fast. Typically vaccines take years to develop. In fact, the quickest any vaccine was developed was 4 years (mumps, 1967). The COVID-19 vaccine was developed in less than a year. How did scientists create the vaccine in record time? How a normal flu vaccine is developed Vaccines, like the one you get for the flu, inject lifeless (inactivated) virus particles into the body. These particles trick the body into thinking it's being infected by the real virus. The body reacts

This rare octopus is transparent letting us see its brain and internal organs.

Wu Yung-sen is a photographer and blackwater diver from Taiwan. He takes a very unique type of underwater photograph that lets us see deepwater creatures we normally would never get to see. To take the pictures, Yung-sen goes to a place in the ocean where the bottom is two-miles deep or more. At this depth, the water is so dark, it is completely black (thus the name - blackwater diving). He then lowers lights into the water and dives under the sea to a depth of about 50 meters where he waits for the sea creatures to show up. Yung-sen says the lights draw plankton to the area. The plankton then draw larger animals - jellyfish, squid, and fish - and Yung-sen quickly snaps the picture. Below is

Check out all the stunning Hubble Space Telescope images NASA just released. Wow!

The geeks at NASA just released a treasure trove of new images taken by the Hubble Space Telescope. The Hubble telescope can take very clear pictures because it orbits above the Earth's atmosphere. The telescope is continually improved by spacewalking astronauts too so the pictures just keep getting better. Check out the newest Hubble Space Telescope images in the picture gallery below. This image shows a small section of the Veil Nebula, as it was observed by the NASA/ESA Hubble Space Telescope. This section of the outer shell of the famous supernova remnant is in a region known as NGC 6960 or — more colloquially — the Witch’s Broom Nebula.

Meat grown in a lab? Break out the lab coats, it’s time to chow down on meat grown in a test tube.

But I don't want to eat a cow! Do you feel bad about your place at the top of the food chain? Does the thought of even eating an animal cracker make you sad? Take heart! Meat-eater-ologists have found a solution that gives us meat without killing an animal. Loosen up your belt and get ready for meat grown in a lab! That's right - quicker than you can say "yuck, you can't make me eat it", scientists can grow up to 80,000 quarter pounder patties from a single tissue sample from a cow. The meat looks like meat, feels like meat, and tastes like meat because, well, it is meat. Under a microscope, you can't tell the difference between animal meat and cultured meat. The

Scientists now know why some people spread viruses more easily than others – the physiology of a superspreader.

Flus and viruses like COVID-19, spread by jumping from person to person. Some people spread viruses more easily than others. In fact, the majority of virus infections come from a very small group of people. The people that more easily spread viruses are called "superspreaders". Now scientists have identified the features that make some people superspreaders. Scientists study superspreaders It's tempting to label superspreadhers as the people who don't cover their mouth when they cough. However, scientists have found that there is much more to it than a person's behavior. Their physiology impacts how easily they spread viruses. Scientists used research studies and computer models of the human head to figure out why some people spread viruses easier than others. They found viruses spread easier when sneeze droplets

Here’s why tree leaves turn brown and fall off in the Winter – and it’s probably not for the reason you thought.

It was once said that a falling leaf was how Summer waves goodbye. The Sun takes a step back, the leaves lull themselves to sleep, and autumn is awakened. But how do tree leaves know when it's time to turn brown and fall to the ground? The wonderfully bizarre process of leaf senescence Leaves of deciduous trees turn yellow and red in a process called leaf senescence. Leaf senescence is the process in which trees suspend their growth and withdraw all the nutrients from the leaves back into the tree limbs. Once the tree has prepared itself for Winter, it drops its leaves to the ground (actually, without the nutrients, the leaves die and fall off). This marks the end of the tree's productive period where it
