Children who eat more ultra-processed foods (UPFs) show stronger responses in the brain's reward network when viewing images of appetizing foods-and these brain responses are linked to increases in body fat one year later. The findings, just published in JAMA Network Open, suggest that the brain may become more sensitive to food cues when children consume more UPFs. UPFs are manufactured food products-such as breakfast cereals, packaged bread and instant soups-that are designed to be highly palatable, convenient and shelf-stable. They often contain artificial sweeteners, colors and other ingredients that people do not typically use when cooking at home. On average, U. S. children get about 67% of their daily calories from UPFs.

The World Health Organization (WHO) has announced the beginning of the first clinical trial of an Ebola vaccine in the outbreak that started in the Democratic Republic of Congo (DRC). WHO’s director-general, Tedros Adhanom Ghebreyesus, said in a social media post on Friday that participants in the trial were vaccinated with the Ervebo vaccine in Bunia, the capital of the DRC’s northeastern Ituri province, which is the epicentre of the Ebola outbreak.

Prostate cancer is the most common cancer in men—in 2013, it affected more than 1 million men across the world. The cancer does not behave the same way in every patient, and doctors have long faced a difficult balancing act between identifying patients who will benefit from more intensive treatment and those who may do just as well without it. Treating someone more aggressively than necessary is associated with increased side effects and poorer quality of life. At a major cancer conference in Madrid, a team from University College London unveiled the latest findings from their STAMPEDE clinical trial, which has shown that adding the hormone therapy abiraterone to the standard treatment for men with high-risk, localized prostate cancer could halve the risk of death from the disease and slow overall progression.

The amazing thing about our pets isn't just the wonderful relationships we get to have with them. These beautiful creatures are actually good for us too, with research showing that petting your dog or cat can lower stress levels, and it's even an effect we can see in the brain. But while the health perks of pet ownership are well known, there's still a lot we don't fully understand about how they emerge. In a new study in Biological Psychology, researchers from the University of Innsbruck in Austria looked into the phenomenon, and their findings suggest that physical touch could be key to the positive effects animals can provide. "Pets enhance their owners' affect and well-being, providing tangible benefits that extend beyond their original utilitarian roles," explains a paper led by first author and psychology researcher Vanessa Kaufmann. "Building on these insights, we sought to elucidate the psychobiological mechanisms through which such benefits arise. "The experiment produced some interesting results.

Windblown sediment moves across the Alaska Highway near the Ä'äy Chù (Slims River) Valley in Kluane National Park and Reserve. Researchers are studying how often fine particles in the dust reach potentially unhealthy levels. (Viktor Elias/CBC)Researchers studying dust storms in the Ä'äy Chù, or Slims River, Valley are hoping new sensors will give them a better picture of how often the storms happen — including through the winter.
