Postpartum depression and bonding: Long-term effects on school-age children

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 ›

An ink that boosts coral reef settlement by 20 times

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 ›

Uncovering compounds that tame the heat of chili peppers

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 ›

UV light and CT scans helped scientists unlock hidden details in a beautifully-preserved fossil Archaeopteryx

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 ›

New global model shows how to bring environmental pressures back to 2015 levels by 2050

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 ›

Scientists discover new way the brain learns

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 downside of taurine: It drives leukemia growth

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 ›

Recognition from colleagues helps employees cope with bad work experiences

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 discover 506-million-year-old predator

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 ›

Not all orangutan mothers raise their infants the same way

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 ›

Mapping a new brain network for naming

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 ›

Eldercare robot helps people sit and stand, and catches them if they fall

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 ›

Hormone cycles shape the structure and function of key memory regions in the brain

Hormone levels fluctuate like the tides, ebbing and flowing according to carefully orchestrated cycles. These hormones not only influence the body, but can cross into the brain and shape the behavior of our neurons and cognitive processes. Recently, researchers used modern laser microscopy techniques to observe how fluctuations in ovarian hormones shape both the structure and function of neurons in the mouse hippocampus, a brain region crucial for memory formation...

Imagine a T-shirt that could monitor your heart rate or blood pressure. Or a pair of socks that could provide feedback on your running stride. It may be closer than you think, with new research demonstrating a particular 3-D ink printing method for so-called smart fabrics that continue to perform well after repeated washings and abrasion tests.
