Teenage depression linked to father's depression

A new study by University College London researchers found a significant association between fathers' depressive symptoms and their teenage children's symptoms of depression. The study, which analyzed data from two large longitudinal studies, suggests that family-focused interventions should also target fathers to prevent depression.

Study finds asthma and food allergies predictable at age 1

A study finds that children with eczema or atopic dermatitis and sensitization to an allergen at age 1 are significantly more likely to develop asthma and a food allergy by age three. The CHILD Study also found that early introduction of common allergenic foods may reduce the risk of allergic sensitization and food allergy.

Manganese-based MRI contrast agent may be safer alternative to gadolinium-based agents

Researchers at Massachusetts General Hospital have developed a potential alternative to gadolinium-based contrast agents for magnetic resonance imaging (MRI). The new manganese-based agent Mn-PyC3A produced comparable image enhancement to the standard of care with rapid clearance and less likelihood of toxicity. The study used a baboon...

NUS researchers identify potential mediator for social memory formation

A study by NUS researchers has identified the potential role of a neuropeptide named Substance P as a mediator of social memory in area CA2 of the hippocampus. This finding suggests that Substance P may play a key role in forming social memories, including distinguishing between familiar and novel faces or objects.

Model sheds new light on pathogen cooperation

A new model reveals that cooperative contagion processes can lead to more severe spread of infectious diseases, generating abrupt outbreak transitions and multi-stability. This discovery highlights the need for new containment strategies to combat epidemics in realistic systems.

Zwicky Transient Facility sees 'first light'

The Zwicky Transient Facility's (ZTF) new survey camera captures hundreds of thousands of stars and galaxies in a single shot, taking its first image of the sky, dubbed 'first light.' ZTF aims to discover objects and events varying in brightness over time, including explosive supernovae, hungry black holes, and asteroids/comets.

How emotions influence our internal clock

A study by Dr. Roland Thomaschke and colleagues found that emotions impact our mental time-processing system, causing faster processing of positive concepts and slower processing of negative ones. This suggests that emotional states can influence human perception, potentially affecting how we respond to advertisements or online content.

Study settles prehistoric puzzle, confirms modern link of carbon dioxide & global warming

A new study resolves a prehistoric climate puzzle by confirming the link between high carbon dioxide levels and global warming for a time interval about 22 million years ago. The research, led by Southern Methodist University, analyzed fossil leaves from Africa and found that carbon dioxide behaved in the same manner millions of years ...

From southeast Asia to the sewers: Study determines new geographical origins of brown rats

A recent study published in Molecular Biology and Evolution reveals that brown rats originally migrated from southern East Asia about 3,600 years ago, spreading rapidly across the globe. The research team identified several genes involved in the immune response that have adaptively evolved under natural selection in wild rats.

Einstein researchers receive $6 million grant to untangle the genetic protections against Alzheimer's disease

Researchers at Albert Einstein College of Medicine are studying the genetic protections against Alzheimer's disease using two existing longitudinal studies on aging. The study aims to identify networks of genes in healthy centenarians that protect them against dementia, which could help identify new targets for drugs to treat Alzheimer's.

Cognitive behavioral therapy for children and adolescents with OCD works in the long run

A study by Aarhus University finds that cognitive behavioral therapy is highly effective in treating OCD in children and adolescents. The research, involving 269 participants from Denmark, Norway, and Sweden, showed that 92% of those who benefited from the treatment remained symptom-free a year after completion.

Making mosquitoes self-destruct

Researchers at UCR have developed transgenic mosquitoes stably expressing the Cas9 enzyme, enabling efficient genome editing to disrupt genes controlling vision, flight, and feeding. The long-term goal is to use these mosquitoes with gene drives to insert genes that suppress disease-spreading insects.
