Acute sense of touch helps hummingbirds hover near a flower without bumping into it      (via sciencedaily.com)     Original source 

Hummingbird flight mechanics have been well studied but far less is known about how their sense of touch helps them sip nectar from a flower without bumping into it. Most of what scientists know about how touch is processed in the brain comes from studies on mammals, but bird brains are very different from mammal brains. New research shows that touch and air pressure on the wings and legs activate specific clusters of neurons in two regions of the forebrain to create a map of their body, which may help hummingbirds make nuanced adjustments to flight.

New antibiotic kills pathogenic bacteria, spares healthy gut microbes      (via sciencedaily.com)     Original source 

Researchers have developed a new antibiotic that reduced or eliminated drug-resistant bacterial infections in mouse models of acute pneumonia and sepsis while sparing healthy microbes in the mouse gut. The drug, called lolamicin, also warded off secondary infections with Clostridioides difficile, a common and dangerous hospital-associated bacterial infection, and was effective against more than 130 multidrug-resistant bacterial strains in cell culture.

Chocolate's tasty flavors might pose a risk in other desserts      (via sciencedaily.com)     Original source 

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.

New research approach: Exploring the mouthfeel of food with a microscope      (via sciencedaily.com)     Original source 

A new perspectives article focuses on different ways to study the mouthfeel of food using atomic force microscopy to better understand the biophysical mechanisms that contribute to taste sensations in a broader sense. New findings in this area could drive the development of health-promoting products that contain less salt, fat, sugar and calories but still have a convincing mouthfeel.

What makes some plant groups so successful?      (via sciencedaily.com)     Original source 

Researchers involved in cataloguing the world's plant species are hunting for answers as to what makes some groups of plants so successful. One of their major goals is to predict more accurately which lineages of flowering plants -- some of which are of huge importance to people and to ecosystems -- are at a greater risk from global climate change.

Fatal attraction: When endangered species try to mate with domestic relatives, both wildlife and people lose      (via sciencedaily.com)     Original source 

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.

Wild megalopolis: Study shows unexpected pockets of biodiversity pepper Los Angeles      (via sciencedaily.com)     Original source 

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.

Intermittent fasting shows promise in improving gut health, weight management      (via sciencedaily.com)     Original source 

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.

New deep learning model is 'game changer' for measuring embryo development      (via sciencedaily.com)     Original source 

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 change, and other external factors, affect humans and animals in the earliest stages of life.

A unified account of Darwinism's varieties      (via sciencedaily.com)     Original source 

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.
