Why we differ in our ability to fight off gut infections
Why we differ in our ability to fight off gut infections
Scientists at EPFL have published two papers showing how genetics affects the ability of different individuals to fight off gut infections. ?he ability of the immune system to fight off bacterial, viral and other invading agents in the gut differs between individuals. However, the biological mechanism by which this happens is not well understood, but at least part of this difference may be explained by genetic factors.

Scientists uncover how an explosion of new genes explain the origin of land plants
Scientists have made a significant discovery about the genetic origins of how plants evolved from living in water to land 470 million years ago. The new study, led by scientists from the universities of Bristol and Essex and published today [16 January] in Current Biology , challenge the established view of the origin of plants on land, and reveal that compared to the origin of animals, plants are better at inventing new genes during periods of evolution.

Finds billions of quantum entangled electrons in ’strange metal’
Physicists provide direct evidence of entanglement's role in quantum criticality In a new study, U.S. and Austrian physicists have observed quantum entanglement among "billions of billions” of flowing electrons in a quantum critical material. The research, which appears this week in Science, examined the electronic and magnetic behavior of a "strange metal” compound of ytterbium, rhodium and silicon as it both neared and passed through a critical transition at the boundary between two well-studied quantum phases.

Should You Take the Bet?
The decision to buy a lottery ticket, gamble on a stock, or buy an insurance policy often comes down to an assessment of risk. How much do I have to lose or gain? For centuries, economists have debated about when somebody should take or walk away from a bet. Now, in new research from Caltech and Yale University, economists are weighing in on the conversation with new mathematical arguments that take a person's overall uncertainty in life into account.

Small change for climate change: Why research funding to save the world needs to be drastically stepped up
Small change for climate change: Why research funding to save the world needs to be drastically stepped up
Researchers from the Norwegian Institute of International Affairs and the University of Sussex analysed USD 1.3 trillion of research funding around the world. Between 1990 and 2018, less than 4.59% of the funding was spent on climate-related research. Only 0.12% of the research funding was spent on a critical issue: how to change societies to mitigate climate change.

Far-right violence in Portugal draws strength from skinhead roots - study
Far-right agitators in Portugal now have different reasons to their 1970s predecessors for becoming radicalised and committing acts of political violence - a new study shows. Influenced by the international ‘skinhead' movement from the mid-1980s, current extremists drawn largely from the working classes have turned to violence to ‘protect' white Portugal and Europe against the ‘threat' posed by multi-racial and multicultural society.

Giant squid’s full genome revealed, providing clues about mysterious creature
The monstrous giant squid, which can grow to the size of a school bus with eyes as big as dinner plates, is rarely sighted and has never been caught and kept alive-meaning its biology (even how they reproduce) is still largely a mystery. But science just took a huge step forward with the publication of the squid's full genome sequence.

#Stayathomeparents tweet anti-spanking beliefs but for some, their behaviors might differ
Stay-at-home parents are likely to tweet anti-spanking beliefs and desires, but those 280-character messages may not always convey what's happening in homes. Despite growing research that spanking leads to children's behavior problems, many parents still support the use of spanking-and among such parents are those who may turn to Twitter and present themselves in a positive manner when discussing child discipline and spanking, according to a new University of Michigan study.

Artificial intelligence used to predict 3D structure of proteins
A deep learning system can predict the structure of a protein using its genetic sequence more accurately than any previous modelling system, according to a study by researchers at DeepMind and UCL. Nearly every function our body performs relies on proteins. Predicting the intricate 3D structure of a protein is important because its structure largely determines its function and, once the structure is known, scientists can develop drugs that target this unique shape.
