From corn chips to tofu, climate change is messing with the menu. A new global study led by the University of British Columbia shows that hotter and drier conditions are making food production more volatile, with crop yields swinging more sharply from year to year. For some, it may mean pricier burgers; for others, it can bring financial strain and hunger. Published today in Science Advances, the study is the first to show at a global scale how climate change is affecting yield swings of three of the world’s most important food crops: corn, soybean and sorghum. For every degree of warming, year-to-year ...

Individuals with an increased risk for dementia due to Alzheimer’s disease can have impaired spatial orientation skills. DZNE researchers come to this conclusion based on a study involving around 100 older adults who were tasked with determining their position within a virtual environment. In this, participants with “subjective cognitive decline” (SCD) – a risk factor for Alzheimer’s disease – performed worse than members of the control group. In contrast, there were no significant differences ...

A new study, led by experts at the University of Nottingham, has found that vegan diets for dogs sold in the UK provide similar nutrition to meat-based diets. The study, led by Rebecca Brociek from the School of Veterinary Medicine and Science, and published in PLOS One, highlights the importance of a balanced and nutritional diet for our canine companions. Dogs, like humans, are omnivores and require specific nutrients rather than specific ingredients. As plant-based diets gain popularity in human nutrition, the pet food industry is following suit with vegan diets becoming ...

(Auburn, AL) Imagine a child with eczema who scratches a patch of irritated skin. A tiny opening forms, invisible to the eye. Into that breach slips a common bacterium, Staphylococcus aureus. For many people, the bacteria would remain harmless. But in someone with a weakened skin barrier, the microbe can cling tightly, multiply, and trigger an infection that is difficult to control. In severe cases, staph spreads beyond the skin and becomes life-threatening. Resistant strains such as MRSA turn what should be a treatable infection into a medical nightmare, one that claims tens of thousands of lives each year in the United States alone. The question that has puzzled ...

A new study reveals the profound emotional and physical toll of extreme morning sickness, with more than half of affected women reporting they considered terminating their pregnancy, and 9 in 10 saying they had thought about not having more children.

It highlights not only ...

Colorectal cancer is unique in having its own microbial ‘fingerprint’ – according to new research from the University of East Anglia. Colorectal cancer is the fourth most common cancer in the UK and the second deadliest. The research could help doctors better understand how this cancer develops, how aggressive it might be, and even how a patient might respond to treatment. The team studied whole genome sequencing (WGS) data from more than 9,000 cancer patients.   The analysis, published today, also challenges scientific claims that all cancers are associated with a ...

Triple-negative breast cancer is particularly aggressive and difficult to treat; but recent research may offer a new way to target the often-deadly disease.   A team of researchers from the University of Mississippi found that coating nanoparticles containing cancer therapies in a sugar-like substance makes them more effective in targeting this cancer. They published their research in Advanced Healthcare Materials.   “It’s called triple-negative because it does not have any of the three things that we have developed treatments to target in cancer,” said Eden Tanner, assistant professor of chemistry and biochemistry. ...

Long-term use of benzodiazepine and related drugs has been linked to poorer quality sleep in older adults with insomnia. While they are cheap, commonly prescribed and widely available in Quebec, these drugs are also addictive: quitting cold turkey can lead to serious withdrawal symptoms, including increased risk of falls, hospitalization and cognitive issues. A new study led by Concordia researchers published in the journal Sleep shows that use of benzodiazepine and benzodiazepine receptor agonists (BZRA) can also affect brain rhythms during sleep that are important for memory and cognitive health in adults aged between 55 and 80. “These drugs don’t ...

Key takeaways: A PICALM gene variant disrupts microglia, the brain’s cleanup cells, reducing their ability to clear harmful proteins and lipids. This dysfunction leads to lipid droplet buildup in microglia, weakening their protective role and raising Alzheimer’s risk. The findings provide a roadmap for drug development targeting genetic risk factors in late-onset Alzheimer’s disease. TAMPA, Fla.
