Almost six million Adelie penguins are living in East Antarctica, more than double the number previously thought, scientists said Wednesday in findings that have implications for conservation.

A set of chemical reactions occurring spontaneously in Earth’s early chemical environments could have provided the foundations upon which life evolved.
The discovery that a version of the Krebs cycle, which occurs in most living cells, can proceed in the absence of cellular proteins called enzymes suggests that metabolism is older than life itself.
It was around 1.6 billion years ago that a community of small, bright red, plantlike life-forms, flitting around in a shallow pool of prehistoric water, were etched into stone until the end of time. Or at least until a team of Swedish researchers chipped their fossilized remnants out of a sedimentary rock formation in central India.
Phosphorus is an essential element which is contained in many cellular compounds, such as DNA and the energy carrier ATP. All life needs phosphorus and agricultural yields are improved when phosphorus is added to growing plants and the diet of livestock. Consequently, it is used globally as a fertiliser – and plays an important role in meeting the world’s food requirements.
In order for us to add it, however, we first need to extract it from a concentrated form – and the supply comes almost exclusively from phosphate mines in Morocco
Fifty-six million years ago, about 10 million years after the dinosaurs went extinct, something strange happened to our planet.
It got hot. Really hot.
Hotter than it had ever been since the Earth formed a few billion years earlier.
As the human species evolved over the last six million years, our resident microbes did the same, adapting to vastly different conditions on our skin and in our mouths, noses, genitalia and guts.
Sharks, rays and skates are able to hunt for prey hidden in the sandy sea floor thanks to their ability to ‘listen’ to their prey’s heartbeat.
These animals have electro-sensory organs that allow them to do this, but until now the way they work has remained a mystery.
A machine learning algorithm helped decode the squeaks Egyptian fruit bats make in their roost, revealing that they “speak” to one another as individuals
Work on gene therapy is showing significant progress for restoring muscle strength and prolonging lives in dogs with a previously incurable, inherited neuromuscular disease. UW Medicine Institute for Stem Cell and Regenerative Medicine scientists are leading the multi-institutional research effort.
A key set of genes involved in honey bee responses to multiple diseases caused by viruses and parasites has been identified by researchers.
The findings are important given that honey bee populations have experienced severe losses across the Northern Hemisphere, mainly due to parasites and pathogens.
Researchers at the University of Virginia School of Medicine have reversed depression symptoms in mice by feeding them Lactobacillus, a probiotic bacteria found in live-cultures yogurt. Further, they have discovered a specific mechanism for how the bacteria affect mood, providing a direct link between the health of the gut microbiome and mental health.
Shaped like a torpedo and about as swift, squids are jet-propelled underwater predators. Together with their nimble brethren, the octopus and cuttlefish, they make for an agile invertebrate armada.
But that was not always the case.
A chemical called BHPF—found in some ‘BPA-Free’ plastics—may cause harmful outcomes in mice, according to a study published Tuesday in Nature Communications.
Scientists figure out how compulsive scratching spreads in mice, and maybe humans
We’ve all felt it. Sitting in the office, you see somebody reach up and scratch their head, or merely hear someone mention being itchy. All of a sudden, you feel the compulsive urge to itch, too. It
A small team of researchers with members from the University of California and the University of Michigan has found that some personality traits unique to a queen wasp are passed down to her offspring, the worker wasps.
In primates such as humans, living in cooperative societies usually means having bigger brains — with brainpower needed to navigate complex social situations.
But surprisingly, in birds the opposite may be true. Group-living woodpecker species have been found to have smaller brains than solitary ones.
