2 giant blobs in Earth’s mantle may explain Africa’s weird geology

Deep within Earth’s mantle, there are two giant blobs. One sits under Africa, while the other is almost precisely opposite the first, under the Pacific Ocean. But these two blobs are not evenly matched.  New research finds that the blob under Africa extends far closer to the surface — and is more unstable — than … Read more

How Paint And a Speaker Could Explain The Physics of The Sun’s Plasma Jets

The Sun is blanketed by spiking, ultra-hot jets of plasma created from electrically charged particles, and now scientists have figured out more about how these jets (or spicules) are created and driven up into the star’s atmosphere.   Via a series of laboratory experiments and models, a new study describes the spicules as being like … Read more

Do You Get Motion Sickness? This Might Explain Why, And What to Do About It

If you’re someone who suffers from motion sickness, travelling in many types of vehicles can be difficult thanks to a host of symptoms like dizziness, lightheadedness, nausea and even vomiting. But it’s not completely clear why some people can read and play games on their phone during a long drive while others spend the journey … Read more

‘Weird’, Long Lost Rocks Could Explain How a Hellish Earth Became Habitable

Early Earth is often described as ‘Hadean’ for good reason. Arising from the ashes of a collision that gave us our Moon, the primordial eon was characterized by hellish heat trapped beneath a thick blanket of carbon dioxide and water vapor.    Strangely those conditions should have been inhospitable for far longer than they were. … Read more

A New Simulation of Mars’s Core Could Explain How It Lost Its Magnetic Field

Mars is a parched planet ruled by global dust storms. It’s also a frigid world, where night-time winter temperatures fall to minus 140 C (minus 220 F) at the poles. But it wasn’t always a dry, barren, freezing, inhospitable wasteland. It used to be a warm, wet, almost inviting place, where liquid water flowed across … Read more

Mind-Bending New Multiverse Scenario Could Explain a Strange Higgs Boson Feature

When researchers at the Large Hadron Collider discovered the elusive Higgs particle in 2012, it was a landmark for particle physics. It solved a very thorny problem, validating and allowing the Standard Model of particle physics to hold.   But, as is often the case with new discoveries, while some questions were neatly answered, others … Read more

Widely available supplement may explain brain boost from exercise | Science

A good workout doesn’t just boost your mood—it also boosts the brain’s ability to create new neurons. But exactly how this happens has puzzled researchers for years. “It’s been a bit of a black box,” says Tara Walker, a neuroscientist at the University of Queensland’s Brain Institute. Now, Walker and her colleagues think they have … Read more

Uranus And Neptune Aren’t The Same Color. A New Study Could Finally Explain Why

Uranus and Neptune are the most twin-like of all the planets in the Solar System. They are almost the same size and mass, have similar compositions and structures, even similar rotation rates.   Which makes one glaring difference quite perplexing. Neptune is a fetching shade of azure, with visible swirling storms. Uranus is more of … Read more

Teeny Tiny 500-Million-Year-Old Fossils Could Help Explain The Evolution of Spiders

Two tiny fossils, each smaller than an aspirin pill, contain fossilized nerve tissue from 508 million years ago. The bug-like Cambrian creatures could help scientists piece together the evolutionary history of modern-day spiders and scorpions.    Still, it’s not clear exactly where these fossils – both specimens of the species Mollisonia symmetrica – fit on the arthropod … Read more

Powerful, nearby black holes could help to explain universe’s origins

The Haro 11 galaxy. Like Tololo 0440-381, this nearby galaxy gives off a type of radiation that scientists think resembles the characteristics of the earliest stars in the universe. Haro 11 is about 300 million light-years away in the constellation Sculptor.  (Image credit: ESA/Hubble/ESO and NASA) Nearby galaxies and their black holes could hold the … Read more
