Increased crevassing across accelerating Greenland Ice Sheet margins (nature.com)
Surface crevassing on the Greenland Ice Sheet is a large source of uncertainty in processes controlling mass loss due to a lack of comprehensive observations of their location and evolution through time.
Earth's inner core may have changed shape, say scientists (bbc.co.uk)
The inner core of Earth may have changed shape in the past 20 years, according to a group of scientists.
Radiation belts detected around Earth after solar storm (sciencealert.com)

Creation of an Atmosphere for the Moon (1969) (rand.org)
The description of a method for creating a lunar atmosphere similar to that of the earth. If the lunar crust were deliberately and methodically broken, simulating earthquake and volcanic activity on the planets, some of the stored gases and vapors could be released to form a lunar atmosphere.
Giant, Mysterious Spires Ruled the Earth Long Before Trees Did (smithsonianmag.com)
When land plants were still the relatively new kids on the evolutionary block and the world’s tallest trees reached only a few feet in height, giant spires of life poked from the Earth.

The deeper under the Earth's surface, the more species you can find (arstechnica.com)
No matter how deep we dig, we keep finding life.
Why did a frozen Earth coincide with an evolutionary spurt? (colorado.edu)
CU Boulder geologists Lizzy Trower and Carl Simpson win $1 million in support from W.M. Keck Foundation to try to solve an evolutionary puzzle and to extend Earth’s temperature record by 2 billion years
Climate Models Can't Explain What's Happening to Earth (theatlantic.com)
Fifty years into the project of modeling Earth’s future climate, we still don’t really know what’s coming.
NASA Is Watching a Growing Anomaly in Earth's Magnetic Field (sciencealert.com)
NASA has been monitoring a strange anomaly in Earth's magnetic field: a giant region of lower magnetic intensity in the skies above the planet, stretching out between South America and southwest Africa.
Thermodynamic model identifies how gold reaches Earth's surface (phys.org)
A research team including a University of Michigan scientist has discovered a new gold-sulfur complex that helps researchers understand how gold deposits are formed.
Three-quarters of the land is drying out, 'redefining life on Earth' (grist.org)
As Earth grows warmer, its ground is becoming drier and saltier, with profound consequences for the planet’s 8 billion inhabitants — nearly a third of whom already live in places where water is increasingly scarce and the ability to raise crops and livestock is increasingly difficult.
Earth's subsurface may hold up to 5.6 × 10⁶ million metric tons of hydrogen (phys.org)
A pair of geologists with the U.S. Geological Survey, Denver, has created a model that shows Earth's subsurface may hold up to 5.6 × 106 million metric tons of natural hydrogen.
Tiny Black Holes Could Have Left Tunnels Inside Earth's Rocks (gizmodo.com)
A pair of imaginative cosmologists have great news for everyone: If a primordial black hole tunnels through your body, you probably won’t die.
Searching for small primordial black holes in planets, asteroids, here on Earth (sciencedirect.com)
Small primordial black holes could be captured by rocky planets or asteroids, consume their liquid cores from inside and leave hollow structures.
GPS constellation as a way to image the ionosphere (2011) (blogspot.com)
Bacterial World (ox.ac.uk)
Bacteria survive, thrive, fight and die by the trillion every moment. They swim using nanoscopic motors, and battle with spears. They sense, communicate, remember. And as scientists discover more about these tiny organisms, it is becoming clear that bacteria wield huge influence over us, shaping Earth’s past, our present and the future for us all. We have only recently realised how much our lives are inextricably linked with the lives of bacteria. We really are living in a bacterial world.
A better approach to gravity: how we made EGM2008 faster (elodin.systems)
For the last month we've been hard at work adding a new feature to Elodin, an ultra-high-speed implementation of EGM2008. EGM2008 – or Earth Gravitational Model 2008 for those acronym phobic readers – a high precision model of Earth's gravitational field.. What once required significant computational resources can now run in milliseconds, unlocking new possibilities for satellite missions, constellation management, and more.
The hunt for heat: Drilling the deepest holes on Earth (bbc.com)
Beneath our feet is an almost limitless source of energy, but while a few lucky locations have geothermal heat close to the surface, the rest of the world will need to dig a lot deeper. The challenge is how to get deep enough.

Effect of a giant meteorite impact on Paleoarchean environment and life (chemistryworld.com)
A giant meteorite that slammed into Earth over 3 billion years ago devastated early microbial life in the oceans, but also freed up a nutrient bonanza.
Magnetic North Pole moves closer to Russia in way never seen before (independent.co.uk)
Scientists have detected unexpected activity in the high Arctic as the magnetic North Pole heads towards Russia in a way that has never been seen before.
Mapping the Ionosphere with Phones (nature.com)
The ionosphere is a layer of weakly ionized plasma bathed in Earth’s geomagnetic field extending about 50–1,500 kilometres above Earth1. The ionospheric total electron content varies in response to Earth’s space environment, interfering with Global Satellite Navigation System (GNSS) signals, resulting in one of the largest sources of error for position, navigation and timing services2.
