The wolves are back in California. So did the “crazy” rumors.

Kent Loudon, a wolf biologist with the California Department of Fish and Wildlife, woke up one morning last year to a flurry of text messages from ranchers in the state’s northernmost county. He was asking about a post with very specific details circulating through Facebook urging people to find a red truck that was transporting breeding wolves along Route 97 to Siskiyou County, California. Loudon was not surprised. This wasn’t the first post of its kind, and it won’t be the last. “Wolves make people crazy,” he said of these…

Scientists have warned that supermassive black holes will collide with each other and distort space and time

A new study has found that two supermassive black holes will merge within 10,000 years, in a collision that will send ripples across the universe. The research, led by a team of astronomers from the California Institute of Technology, found that two supermassive black holes, about 9 billion light-years away in deep space, orbit each other every two years. Each supermassive black hole has a mass hundreds of millions of times greater than the mass of our Sun. Furthermore, the two objects are relatively close to a distance of 1,950…

Scientists discover a puzzling new material in the heart of the Earth

Scientists have claimed that the Earth’s core is neither solid nor liquid, as we have long believed, but something “completely abnormal”. In fact, they think it’s a strange combination of elements that make it a bit of a bit of the two. Or, as the experts called it,super ionic state.“ Deep within it is a mixture of “lighter” elements, along with super-hot solid and liquid states. These molecules include hydrogen, oxygen and carbon, which rotate in a mesh-like iron lattice. “It’s quite abnormal,” said Professor He Yu, who led the…

Dolly, Dolly Clone sheep

Twenty-five years ago on this day, the sheep Dolly became the first animal to be cloned using an adult somatic cell. Dolly’s experience exploded in the news around the world. It changed the world of stem cell research — and on a more personal level, it kept the institute that hosted the experiment alive. Alan Archibald, who was part of the 1996 experiment facilitated by the UK’s Roslin Institute, told DW with a laugh. We were facing government cuts. And the money we earned selling Dolly’s intellectual property kept us…

Astronomers discover the planet where it rains gems and mineral clouds

Usually rainy days are very miserable but that is not the case in a faraway planet where it can make you rich. Experts believe that a huge exoplanet located 855 light-years away rains on liquid sapphires and sapphires. WASP-121 b, as the planet is known, is home to clouds of vaporized metals rather than the thinner stuff we get back here on Earth. Clouds on the planet consist mainly of metals such as iron, magnesium, chromium, and vanadium. “This rain will be different from any known rain in the solar…

Exposed parasitic wasp: one species is actually 16

mohmad free

Ormyrus’s tiny iridescent bot has long looked suspicious to a parasitic wasp. It wasn’t the amazing beauty of the hornets – wasps can be traditionally attractive too – but their strategy in life. Parasitic wasps lay their eggs on or inside insects and other arthropods, and the larvae eat their way out when they hatch. Each type of parasitic wasp tends to favor one host or several families. But Ormyrus labotus has been observed laying eggs in more than 65 different species of insects — more than one or a…

When science is hard work to follow

The COVID pandemic may finally fade as case numbers drop dramatically, but there are many who don’t want to let it go. Virologists and public health professionals who have left their labs and platforms to express their opinions publicly don’t want to give up the dash of a camera moment or the glare of a truck with satellite cameras coming outside their doors. Professors who used to sleep students in their classrooms suddenly entered the epicenter of a two-year social media war and watched their Twitter followers swell to hundreds…
