Researchers discover how human immune receptors become activated in the presence of harmful substances

In George Orwell's classic dystopian novel Animal Farm, as the barnyard devolves into chaos the slogan "all animals are equal" quickly becomes "all animals are equal but some animals are more equal than others". The same might be true for the tiny immune receptors scattered across the surface of our T-cells. Before now, it was unclear how these complex molecular receptors recognised harmful invaders (or antigens) and sent warning signals into the cell. It was largely assumed that "all receptors were equal".

TD9 Development up to 2016-08-31, then +5 Day Forecast.

TD9 Development up to 2016-08-31, then +5 Day Forecast.

This animation models surface winds of the development of TD9 up to the current day, 2016-08-31, then seamlessly shows the +5 day potential path of the storm, up to 2016-09-01. The entire sequence is then repeated showing wind power density. Data from the GFS 2016-08-31T06:00Z run.

Hurricane Gaston makes an appearance then spins out of the frame harmlessly.

Dogs Understand Human Words and Intonation

Dogs Understand Human Words and Intonation

Dogs have the ability to distinguish words and the intonation of human speech through brain regions similar to those that humans use, a study in the 2 September issue of Science reports. The results reveal important insights into the neural networks needed to understand speech, hinting that perhaps both humans and dogs may have relied on similar networks that were already in place before language evolved, and later adapted to process speech.

People enhanced the environment, not degraded it, over past 13,000 years

People enhanced the environment, not degraded it, over past 13,000 years

Human occupation is usually associated with deteriorated landscapes, but new research shows that 13,000 years of repeated occupation by British Columbia’s coastal First Nations has had the opposite effect, enhancing temperate rainforest productivity. Andrew Trant, a professor in the Faculty of Environment at the University of Waterloo, led the study in partnership with the University of Victoria and the Hakai Institute. The research combined remote-sensed, ecological and archaeological data from coastal sites where First Nations’ have lived for millennia.

The U.S. plans to build the most advanced fusion reactor ever

The U.S. plans to build the most advanced fusion reactor ever

The US government has put its weight behind efforts to create an economically viable fusion reactor, endorsing a new category of designs that could become the most efficient and viable yet. Re-creating the atom fusing processes that sustain the sun on Earth has long been one of the holy grails of modern physics. Hydrogen fusion has been powering out Sun for the past 4.5 billion years now, and it’s still going strong — a machine that could safely and stably harvest these processes would offer humanity safe, clean, and virtually endless energy.
