65 536 shades of grey can help us understand our geological past

Based on images from the Mars rover Curiosity, researchers believe floods of unimaginable magnitude once washed over Mars. “They’re trying to justify a lot of things that you can’t really know based on a few pebbles”, says professor at the University of Oslo.
What kind of animal is actually capable of spreading a huge avocado seed? And why does the tree Maclura pomifera make huge fruits that no one wants to eat? These are plants that are still waiting for ‘friends’ that will never return.
What really happens in the brain when a baby suddenly starts to smile? Or when a toddler from one day to the next becomes interested in playing with other children? Norwegian researchers believe they’ve discovered a clue from creatures that are completely different from us.
Using surgically implanted sensors, researchers have for the first time been able to measure precisely what happens in the body of the moose during the changing seasons. Their body temperature and pulse are at their lowest in early spring - when conditions are the toughest.
Among their findings is that ice age cycles suddenly became stronger just over 600,000 years ago. Researchers were also struck by how little plant life has changed over the past 1.7 million years.
Weeds are no longer just plants we want to get rid of. Many people are concerned about biodiversity, while others have become increasingly captivated by harvesting wild plants to eat.
The researchers' goal is to create artifical cells that can for instance knock out a type of cancer or neutralize harmful substances in the body. Now they are sharing their images of how life's tiny building blocks behave under the microscope.
Our cells contain a previously unknown layer of information. This layer facilitates a whole new level of regulation that might make us more adaptable. Or sick, when the system fails. Welcome to the new world of epitranscriptomics.
Jessica Lönn-Stensrud was holding her new-born daughter in her arms when she heard that three infants had died in an outbreak of antibiotic-resistant intestinal bacteria at a maternity ward in Sweden. Fear hit her like a punch to the stomach. Ten years later, she has become the micro-organisms’ noble defender.
An American brain researcher warns that we may already be "perilously close" to crossing ethical boundaries. At the same time, research on so-called mini-brains can provide great opportunities to unlock some disease mysteries.
A POST FROM THE SUB-GLACIAL BLOG: After a steep walk up the mountain, we arrived in front of the tunnel entrance. There we stood, in shorts and t-shirts, suddenly realising that the heat and sunshine we were used to until now were about to become only a distant memory. With our winter coats, hats and gloves on, we followed Miriam as she opened the door leading into the mountain.
SHARE YOUR SCIENCE: During winter, a thick layer of ice can form on the surface of the northern Norwegian fjords. The knowledge of the varying conditions of this ice can be applied to understand to protect and aid the Arctic in the future.
The serious warnings of the latest IPCC report lost the battle for media attention to Brexit, Trump, and the US mid-term elections. But it’s time to sit up and take notice. For small island states that face loss of sovereignty due to climate change, the clock is already ticking, warns climate researcher Adelle Thomas from the Bahamas.
Our warming planet is pushing some plant and animals species towards extinction. But there’s actually no such thing as untouched nature — humans have always altered their environment. That doesn’t mean we shouldn’t do our best to protect what’s here now.
