What makes chocolate taste and smell so delicious? Chemistry, of course! A variety of molecules work together to create that unmistakable aroma, but those same molecules might carry some unwanted health effects if there are too many around. While many of the compounds appeared in chocolate in low enough concentrations to be safe, higher amounts were found in some baked sweet treats. Read more ›

Advances in electrochromic coatings may bring us closer to environmentally friendly ways to keep inside spaces cool. Like eyeglasses that darken to provide sun protection, the optical properties of these transparent films can be tuned with electricity to block out solar heat and light. Now, researchers report demonstrating a new electrochromic film design based on metal-organic frameworks (MOFs) that quickly and reliably switch from transparent to glare-diminishing green to thermal-insulating...

New research has revealed a previously unknown biological process through which breast tumor cells develop resistance to standard treatment, which could open the door for cancer scientists around the world to further target this vulnerability in hopes of creating more effective therapies for disease. Additionally, the research team tested a promising drug in combination with an existing therapy that achieved total remission in one breast cancer model that was resistant... Read more ›

Over the past few decades, there has been a significant increase in the prevalence of depression in adolescents and young adults -- and a simultaneous uptick in the inclusion of technology and social media in everyday life. In a new study, researchers investigated the association among social media use, depression and other health-related behaviors of young adults over time. Read more ›

Researchers have successfully tested a novel technique for probing deep into the human brain, without surgery, for potential therapeutic purposes. In the rapidly evolving field of neuroscience, non-invasive brain stimulation is a new hope for understanding and treating a myriad of neurological and psychiatric conditions without surgical intervention or implants.

Sticks and stones aren't enough to thwart biological attraction, but sometimes those are the only tools available to pastoralists trying to prevent wildlife from eloping with their livestock. A new study brings awareness to both the human impacts of these encounters -- ranging from economic loss to death -- and conservation concerns for the wild animals that are often endangered.

Researchers, in partnership with the city of Los Angeles, have developed the urban association index to help identify how well or poorly individual wildlife species are doing in the city. The researchers found unexpected pockets of biodiversity deep in the city, but they say it will still be a challenge to elevate Los Angeles' overall level of biodiversity. Read more ›

Researchers have shown that members of the public have little trouble in learning very quickly how to use a third thumb -- a controllable, prosthetic extra thumb -- to pick up and manipulate objects. The team tested the robotic device on a diverse range of participants, which they say is essential for ensuring new technologies are inclusive and can work for everyone. Read more ›

Participants following an intermittent fasting and protein-pacing regimen, which involves evenly spaced protein intake throughout the day, saw better gut health, weight loss and metabolic responses. These benefits were notably greater than those seen with simple calorie restriction. The findings could advance our understanding of the relationship between the gut microbiome and metabolism and improve strategies for managing obesity. Read more ›

A new deep learning model performs a task that biologists have struggled with for centuries -- how to measure the incredibly complex process of embryonic development. Scientists have shown that the AI model, known as Dev-ResNet, can identify what happens and when during embryonic development, from video. While used in pond snail embryos for this study, in future the technique could be used to help accelerate understanding on how climate... Read more ›

A new article examines the question of what Darwinism is and how its nonscientific uses relate to the scientific theory of evolution. The authors observe that while some people claim Darwinism's meaning should be limited to scientific content, others call for its abolition altogether. The authors propose a unified account of these varieties of Darwinism. Read more ›
