Prenatal exposure to combustion-related pollutants and anxiety, attention problems in young children

A study published in Environmental Health Perspectives found that prenatal exposure to combustion-related pollutants was significantly associated with symptoms of anxious/depressed and attention problems in young children. High levels of polycyclic aromatic hydrocarbons (PAH) were measured in mothers' air samples and umbilical cord blood.

False killer whales use acoustic squint to target prey

Researchers discovered that false killer whales can focus their echolocation beams on targets using a strategy called 'acoustic squint', increasing beam width when faced with harder tasks. By plotting the path of acoustic beams, they found that wider beams were focused furthest away, allowing Kina to target specific objects.

Home alone -- depression highest for those living alone

New research published in BMC Public Health found that people living alone have an increased risk of developing depression, with women's risk attributed to sociodemographic factors such as lack of education and low income. The study identified poor housing conditions and lack of social support as key contributory factors.

Non-drug treatments help alleviate symptoms of treatment-induced menopause in breast cancer patients

Researchers found that cognitive behavioural therapy (CBT) and physical exercise can significantly reduce menopausal symptoms, such as hot flushes and vaginal dryness, in breast cancer patients undergoing treatment. The interventions also improved sexuality and physical functioning, with positive effects still apparent after six months.

Sediment sleuthing

A University of Delaware oceanographer found trace amounts of radioactive iodine in the Delaware River, providing a new way to study substance travel through rivers to the ocean. The contaminant enters waterways via wastewater treatment systems and has a half-life of eight days.

Why WikiLeaks' bid for radical transparency failed

New research reveals four key reasons why radical transparency is hard to achieve, including the limits of technological fixes, intermediary challenges, and government responses. The analysis highlights that information has no transformative power in its raw form, requiring distillation and interpretation to capture audience attention.

NIH study finds interventions to prevent Type 2 diabetes give good return on investment

A new NIH study finds that programs to prevent or delay type 2 diabetes in high-risk adults can improve quality of life, reduce healthcare costs, and result in significant savings over time. Lifestyle interventions and metformin treatment were found to be cost-effective options for preventing type 2 diabetes.

A new shortcut for stem cell programming

The University of Bonn team has successfully derived brain stem cells directly from connective tissue in mice, which can reproduce and be converted into various types of brain cells. This method is faster, safer, and associated with a lower risk of tumors compared to existing approaches.

How music prevents organ rejection

Research published in BioMed Central's Journal of Cardiothoracic Surgery found that opera and classical music increased survival time before organs failed. Music may act via the parasympathetic nervous system, reducing inflammation and increasing regulatory cells.

Gennadi Henkin receives Bergman Prize

Gennadi Henkin has received the 2011 Stefan Bergman Prize for his fundamental contributions to theory of functions on complex manifolds, integral representations in several complex variables, and multidimensional Cauchy-Riemann equations. He is recognized as a leading scientific researcher with over 130 publications in various fields.

Anxiety boosts sense of smell

A new study found that anxious individuals can detect negative odors more accurately due to heightened sensory perception, leading to increased anxiety responses.
