In many neurodegenerative diseases, proteins misfold and clump together in brain tissue. Scientists developed a new therapy made of peptides and a sugar that naturally occurs in plants. The therapeutic molecules self-assemble into nanofibers, which bond to the neuron-killing proteins. Now trapped, the toxic proteins can no longer enter neurons and instead harmlessly degrade.

Apples-to-apples comparisons in the distant universe are hard to come by. Whether the subject is dwarf galaxies, supermassive black holes, or 'hot Jupiters,' astronomers can spend months or years searching for comparable objects and formations to study. And it is rarer still when those objects are side-by-side. But a new study offers a road map for finding 'twin' planetary systems -- showing whether binary stars that orbit each other, and...

Postpartum maternal mental health and mother-to-infant bonding are well-established as critical factors in a child's psychosocial development. However, few studies have explored the combined impact of postpartum maternal depression and early bonding experiences on emotional and behavioral difficulties during middle childhood. A new study reveals significant associations between postpartum depression, mother-to-infant bonding, and child difficulties. Notably, secure early bonding was found to partially buffe Read more ›

With coral reefs in crisis due to climate change, scientists have engineered a bio-ink that could help promote coral larvae settlement and restore these underwater ecosystems before it's too late. Researchers demonstrate that the ink could boost coral settlement by more than 20 times, which they hope could contribute to rebuilding coral reefs around the world. Read more ›

Evidence of a unique T cell may explain why urban children are more prone to allergies than rural children. Differences in the development of the gut microbiome may be an underlying cause. Read more ›

Using a new fluorescent mouse model with advanced imaging techniques, researchers have successfully visualized how musculoskeletal components are integrated into the functional locomotor system during embryonic development. Read more ›

When biting into a chili pepper, you expect a fiery sensation on your tongue. This spiciness is detected because of capsaicinoid compounds. But for some peppers, despite high levels of capsaicinoids, the heat is mysteriously dull. Now, researchers have identified three compounds that lessen peppers' pungency. These results challenge the reliability of the century-old Scoville scale, which traditionally bases its rating on two capsaicinoids. Read more ›

Archaeopteryx is the fossil that clearly demonstrated Darwin's views. It's the oldest known fossil bird, and it helps show that all birds -- including the ones alive today -- emerged from dinosaurs. And while the first Archaeopteryx fossil was found more than 160 years ago, scientists are continuing to learn new things about this ancient animal. A set of feathers never before seen in this species help explain why it... Read more ›

A new study finds that with bold and coordinated policy choices -- across emissions, diets, food waste, and water and nitrogen efficiency -- humanity could, by 2050, bring global environmental pressures back to levels seen in 2015. This shift would move us much closer to a future in which people around the world can live well within the Earth's limits. Read more ›

Neuroscientists have discovered that the brain uses a dual system for learning through trial and error. This is the first time a second learning system has been identified, which could help explain how habits are formed and provide a scientific basis for new strategies to address conditions related to habitual learning, such as addictions and compulsions. The study in mice could also have implications for developing therapeutics for Parkinson's. Read more ›

A study shows that leukemia cells drink up taurine, which is produced in the body and also consumed through foods and in energy drinks, and use it as fuel for growth. This highlights a potential to block taurine uptake as a possible treatment. Read more ›

Being appreciated by colleagues can help employees cope with negative experiences at work, according to a new study. Researchers found that employees experience 'embitterment' -- an emotional response to perceived workplace injustice -- on days when they are assigned more unreasonable tasks than usual. This negative emotion not only affects their work but also spills over into their personal lives, leading to an increase in rumination, the repetitive dwelling on... Read more ›

Palaeontologists have discovered a remarkable new 506-million-year-old predator from the Burgess Shale of Canada. Mosura fentoni was about the size of your index finger and had three eyes, spiny jointed claws, a circular mouth lined with teeth and a body with swimming flaps along its sides. These traits show it to be part of an extinct group known as the radiodonts. Read more ›

Sumatran orangutan mothers differ from one another in how they behave with and take care of their infants and how flexibly they adjust their mothering behaviors as their infants grow. Whilst mothers differed from one another in their maternal behaviors, they remained consistent in their behaviors with their different infants. Consistent differences among Sumatran orangutan mothers suggest that individual maternal personalities may exist, potentially influencing infant development. Read more ›

Researchers identified two brain networks involved in word retrieval -- the cognitive process of accessing words we need to speak. A semantic network processes meaning in middle/inferior frontal gyri, while an articulatory network in inferior frontal/precentral gyri plans speech production. Read more ›

Engineers built E-BAR, a mobile robot designed to physically support the elderly and prevent them from falling as they move around their homes. E-BAR acts as a set of robotic handlebars that follows a person from behind, allowing them to walk independently or lean on the robot's arms for support. Read more ›
