Did the Vikings Get a Bum Rap?


The Vikings gave no quarter when they stormed the city of Nantes, in what is now western France, in June 843—not even to the monks barricaded in the city's cathedral. "The heathens mowed down the entire multitude of priest, clerics, and laity," according to one witness account. Among the slain, allegedly killed while celebrating the Mass, was a bishop who later was granted sainthood.

Remarkable Limb Regeneration Began 300 Million Years Ago


Fossilized, primitive amphibians with odd-looking appendages, some with extra toes and deformed shapes, suggest the ability of some vertebrates to regenerate or regrow amputated limbs first evolved at least 300 million years ago.

Salamanders are the only modern four-legged vertebrates, or animals that have backbones, able to fully regenerate their limbs into adulthood.

Humanity Has More Mothers Than Fathers, DNA Reveals


Mothers outnumbered fathers throughout much of human history, a new DNA analysis of people around the world shows.

How Diversity Makes Us Smarter


The first thing to acknowledge about diversity is that it can be difficult. In the U.S., where the dialogue of inclusion is relatively advanced, even the mention of the word “diversity” can lead to anxiety and conflict. Supreme Court justices disagree on the virtues of diversity and the means for achieving it. Corporations spend billions of dollars to attract and manage diversity both internally and externally, yet they still face discrimination lawsuits, and the leadership ranks of the business world remain predominantly white and male.

Paralysed rats takes 1,000 steps thanks to remote-controlled technology


A team at the the École Polytechnique Fédérale in Switzerland has restored movements to entirely paralysed rats, allowing them to walk fluidly on their hind legs while their upper bodies are supported by a tiny harness. The technique involves zapping the rat’s spinal cord with electrical pulses to replace the commands that are normally sent out by the brain, but are obscured when the spine is severely injured.

Mantis shrimps can see cancer, and scientists have now created a camera that does the same


Scientists from the University of Queensland in Australia have discovered that mantis shrimp have an incredibly useful ability - the marine creatures are able to see a variety of cancers inside our bodies. And they've now replicated that ability in a camera that could eventually be put into a smartphone.

Brain scans reveal 'gray matter' differences in media multitaskers


Simultaneously using mobile phones, laptops and other media devices could be changing the structure of our brains, according to new research. People who frequently use several media devices at the same time have lower grey-matter density in one particular region of the brain compared to those who use just one device occasionally.

Diet affects sperm competitiveness


It's well known that omega-3 long-chain polyunsaturated fatty acids (n-3 LC-PUFA) can help to prevent heart disease but new research has found that these essential fatty acids can also increase the chance of paternity success.

The results published today in the Royal Society journal Biology Letters looked at the guppy Poecilia reticulata, a live-bearing fish with a highly promiscuous mating system in which sperm typically compete for fertilisations.

Bacterial 'communication system' could be used to stop, kill cancer cells, study finds


A molecule used as a communication system by bacteria can be manipulated to prevent cancer cells from spreading, a study has demonstrated. "During an infection, bacteria release molecules which allow them to 'talk' to each other," said the lead author of the study. "Depending on the type of molecule released, the signal will tell other bacteria to multiply, escape the immune system or even stop spreading.".

The Man on a Quest to Open-Source Cancer Research


Isaac Yonemoto is a chemist, but he’s been writing software code since he was a kid. He calls himself a “semi-recreational” programmer, and now, he’s running an experiment that combines this sideline with his day job. In short, he’s using open source software techniques to kickstart the world of cancer research.

Manly faces aren’t first pick in all cultures


A new study could debunk the theory that women living where rates of infectious disease are high prefer men with faces that shout testosterone when choosing a mate.

By the end of the study, that theory crumbled amid patterns too subtle to detect when tested with 962 adults drawn from 12 populations living in various economic systems in 10 nations.
