This week's science news was way over our heads, as astronauts and space agencies rocketed to the front pages. Topping the list is the early return of the International Space Station's (ISS) Crew-11 on Thursday (Jan. 15) due to a medical event.
News of the crew's early return, the first in the station's 25-year history, was announced less than a week before. It was prompted when one of its astronauts experienced an undisclosed medical issue. The evacuation leaves the ISS occupied by only four astronauts until the arrival of the replacement Crew-12 next month.
Earth's biggest river deltas are rapidly sinking
18 of Earth's biggest river deltas — including the Nile and Amazon — are sinking faster than global sea levels are rising
Our world is rapidly warming, so it's no surprise that rising sea levels are the biggest cause of land loss in coastal regions.
Yet a startling study revealed that this isn't the case everywhere. The research published this week found that the world's biggest river deltas — including the Nile, Amazon and Ganges — are now sinking faster than the seas are rising.

The combination of rising oceans and sinking land means the world's largest cities will face even greater challenges from catastrophic floods in the future.

How much of your body could you lose — and still survive?
Monty Python's Black Knight may insist that losing all four of his limbs in quick succession is "only a flesh wound," but just how much of the human body can be removed without a person dying? As it turns out, it's much more than you might think.

Woolly rhino flesh in wolf reveals extinction mystery clue
Woolly rhino flesh pulled from ancient wolf stomach gives clues to ice age giant's extinction
The last meal of a wolf pup that was naturally mummied 14,400 years ago in Siberian permafrost is helping scientists unravel the fate of the woolly rhino (Coelodonta antiquitatis) and the reasons behind the ice age giant's extinction.
By extracting a piece of woolly rhino flesh from the wolf's stomach and sequencing the genome of the partially digested chunk, scientists discovered that the horned beast existed in a genetically uniform population that may have struggled to adapt to ancient climate change.
But the new genome is just one strand of evidence in the mystery of the rhino's extinction. In a win for science, this is the first time scientists have recovered the DNA of an ice age animal from the stomach of another one.

Science long read
Forced closure of premier US weather-modeling institute could endanger millions of Americans
In December, The Trump administration announced plans to dismantle the National Center for Atmospheric Research (NCAR), describing it as "one of the largest sources of climate alarmism in the country."
Yet whether it is forecasting high winds, wildfires, floods or hazards in the air and space, the research center is at the forefront of world weather and climate research and vital for reducing risk. In this long read, Live Science investigated the work done by the center and the likely consequences of shutting it down.

Giant cosmic 'sandwich' is the largest planet-forming disk ever seen — Space photo of the week
The Hubble Space Telescope's shot of "Dracula's Chivito" — a protoplanetary disk that earned its nickname due to its gothic-tinged likeness to a Uruguayan sandwich — has captured a stunning insight into how planets form.
Spanning nearly 400 billion miles (640 billion kilometers) and containing a hot star at its center, the system is the largest planet-forming disk ever observed around a young star.
