A "monster" planet, which should in theory not exist, has been discovered orbiting a faint dwarf star far, far away, surprised astronomers said Tuesday. The existence of the gassy giant challenges long-standing theories that such a big planet -- about the size of Jupiter -- cannot be formed around a star so small. Theory had predicted that small stars can form rocky planets, "but do not gather enough material together to form Jupiter-sized planets," Britain's Royal Astronomical Society said in a statement.
Martin Luther's 95 Theses Are 500 Years Old. Here's Why They're Still Causing Controversy
It is logically, theoretically and mathematically impossible to stop the aging process, scientists have said. In a blow to researchers currently working to slow or even stop the detrioration of cells in the human body, Joanna Masel and Paul Nelson, from the University of Arizona, have found a catch-22 when it comes to anti-aging science: it can cause cancer. In their research, published in the Proceedings of the National Academy of Sciences, Masel and Nelson looked at exactly what happens to cells in the body as they age to see if there is any way to halt the process in multicellular organisms like humans.
There is a "catastrophic" gap between national pledges to reduce greenhouse gas emissions and the actions needed to cap global warming below two degrees Celsius, the UN's environment chief warned Tuesday, days ahead of global climate talks in Bonn. Record-setting extreme weather in 2017 -- including monsoon flooding, raging fires, and a trio of deadly hurricanes -- likely bears the fingerprint of global warming, it noted. "One year after the Paris Agreement entered into force, we still find ourselves in a situation where we are not doing nearly enough to save hundreds of millions of people from a miserable future," said Eric Solheim, head of the UN agency.
The oceans of modern day Earth are scary enough already, with all kinds of creatures that could make your blood run cold if you accidentally happened upon one, but back in the Jurassic period things were no safer. If you were taking a dip in the Jurassic ocean, an ichthyosaur would have been one of the more intimidating animals you could bump into, and the fossilized remains of one was just discovered in India for the very first time.
The specimen measures some 18 feet long, though they could reach as large as 30 feet, and this particular example is remarkably well preserved. But the part of the these new fossils that is most exciting to the researchers is its jaw, and the lessons its teeth can teach us about what the massive beast ate on a daily basis.
The nearly 20-foot-long aquatic reptile was a big fan of eating crunchy ocean creatures, and its remains were discovered in proximity to what scientists believe were its typical daily fare. Mollusks and other shelled sea animals were all fair game for dinner, and the ichthyosaur's powerful jaws and robust teeth made short work of them.
"We could infer from wear patterns on its teeth that this ichthyosaur was a top-tier predator that fed on hard and abrasive food material, including marine molluscs (ammonoids and belemnites), fish and possibly other marine reptiles," lead researcher Guntupalli Prasad explains in an interview published in PLOS One.
The researchers are hopeful that continued exploration in the region will help them uncover even more fossils, and potentially spark further interest for paleontologists in India.
Around 130 dead seals have washed up on the shores of Russia's Lake Baikal, authorities said Tuesday, as they launched a probe into the latest problem to hit the world's deepest lake. The Baikal seal is the smallest in the world, and exactly how and when the species colonised the ancient Siberian lake is still a mystery. "There were about 130 animals found dead" over the past few days, said environmental ministry spokesman Nikolai Gudkov.
Your bathroom is probably the most boring place in your house — unless you're one of those people that has the multi-person walk-in showers with like 10 different nozzles that envelop you in a storm of amazing cleanliness — but it doesn't have to be. Adding some glow-in-the-dark plutonium soap will definitely spice up the joint a little, though its use cases are probably somewhat limited.
The glowy bar, which is perfectly acceptable as hand soap or to toss in the shower, took Reddit by storm, and it's sold by a company (fittingly) named United Nuclear. The company specializes in all kinds of science supplies and equipment, and they have plenty of quirky gift-like items as well, which is where this soap comes in.
"Vegan-friendly, contains no animal products and of course contains no actual Plutonium, just a little of our safe, non-toxic aqua glow pigment," the site description reads. "Plutonium soap bar has data printed in it from the periodic table and glows aqua in color. A great gift for anyone interested in science/chemistry/technology/nuclear stuff. Made with our Europium UltraGlow®, non-toxic, non-radioactive, glow-in-the-dark pigment."
So, it's bare-bones soap with some funky lettering and an awesome glow effect. There's no arguing that it's pretty neat, but I'm personally having a hard time imagining a scenario where I'd even get the chance to use the soap when it's glowing. Like most glow-in-the-dark products, it needs light to charge it up, so unless you're going to shine a flashlight on it then take it into a dark shower, it might not be all that cool.
Just kidding. It's plutonium soap! Of course you're going to buy it!
