Researchers discovered striking similarities and differences in how dog and human brains process visual information about others. Faces are central to visual communication in humans, who possess a dedicated neural network for face processing. Although dogs also pay attention to faces, excel at eye contact and at reading facial emotion, they also rely on additional bodily signals to communicate. Ar
Even though dogs gaze into man's eyes, dog brains may not process faces as human brains do. A new study from JNeurosci suggests that the canine visual system is organized differently: the face network found in primates may not extend to all mammals.
Study of brain activity shows no difference when dogs see back or front of a head Dog owners might love their pet's endearing puppy dog eyes and cute furry features, but it turns out the doggy brain is just as excited by the back of our heads as the front.

The whole point of Cal Cunningham was that he was supposed to be boring. The North Carolina Democrat is not the most dynamic campaigner, but polls have consistently given him a lead over the Republican incumbent, Thom Tillis, in the race for U.S. Senate. Now that lead is up in the air. On Thursday, a report revealed texts between Cunningham, a married father of two, and a Democratic strategist. T
The global quest to use a person's breath analysis for rapid, inexpensive and accurate early-stage testing for cancer and other diseases has taken a leap forward. In a new paper in the British Journal of Cancer, Flinders University researchers have reported significant progress in developing a method to test exhaled breath profiles which accurately differentiate head and neck cancer from non-cance
Current 3D printers employ either plastic or metal only, and the conventional method to coat 3D plastic structures with metal is not environment-friendly and yields poor results. Now, scientists from Waseda University, Japan, have developed a metal-plastic hybrid 3D printing technique that produces plastic structures with a highly adhesive metal coating on desired areas. This approach extends the

Sea level rise will cause rivers to jump course, a phenomenon called avulsion, more often on deltas than in the past, research has found. The same team has now discovered that a perfect storm of factors—including larger floods and finer sediment size—will enable these destructive events to occur farther and farther inland. The results, which appear in Geophysical Research Letters , warn of major
When Donald Trump's case of COVID-19 became known, commentators began reaching for adjectives, starting with Shakespearean . It is well that they did not call the situation a Greek tragedy, because that would presume a tragic flaw, be it the outrageous arrogance of a formidable figure known as hubris or a virtue that carried the hero over the edge. But is the Bard, at least, being properly evoked

Though the country is a huge polluter, it leads the world in the clean technologies that could make this feasible When I first moved to China in 1990, winter meant coal. The moment Beijing turned on the municipal heating system, our faces would become covered with soot. People stockpiled loose coal in huge piles outside their homes for heating and cooking. I could see the smokestacks of four larg
American history is driven by periodic moments of moral convulsion. The late Harvard political scientist Samuel P. Huntington noticed that these convulsions seem to hit the United States every 60 years or so: the Revolutionary period of the 1760s and '70s; the Jacksonian uprising of the 1820s and '30s; the Progressive Era, which began in the 1890s; and the social-protest movements of the 1960s an
Earth is so far the only planet in the universe which we know contains life. There are many other worlds in our own solar system that may contain life (or did at one time), but none confirmed. Part of the goal of the exoplanet exploration program is to determine how many worlds out there are capable of supporting life. This requires that we come up with some specific definition of a habitable wor
Bone broth is a stock made from bones, water, and other nourishing ingredients. (Tim MacWelch/) This story was originally featured on Outdoor Life . It's so ubiquitous that your local grocery store now stocks it, and so trendy that complete diet plans are being built around it. But bone broth is more than a traditional food source or recent health fad. It's also a great way to add more nutrients

If you visit a particular stretch of South Africa's Cape South coast, about 400km east of Cape Town, you are stepping back in time—in more ways than one. That's because hundreds of fossil tracksites dot the area. These sites date back to between 400,000 and 35,000 years ago, during the Pleistocene Epoch. They occur in aeolianites (cemented dunes) and cemented foreshore deposits, the remains of dun
