A better biomonitor for children with asthma

A team of researchers at Tel Aviv Sourasky Medical Center developed an Induced Sputum (IS) technique to assess the effect of pollution on urban asthmatic children. The study found that IS is a more physiologically sensitive biomonitoring method than environmental sampling stations, detecting hazardous particles like mercury in the lungs.

Study finds eczema, short stature not associated overall

A study published in JAMA Dermatology analyzed data from nine population-based studies and found no overall association between eczema and short stature. However, a small group of children with severe eczema who experienced sleep disturbances showed potentially reversible growth impairment.

Drug developed at Pitt proves effective against antibiotic-resistant 'superbugs'

A treatment pioneered at the University of Pittsburgh Center for Vaccine Research is far more effective than traditional antibiotics in inhibiting the growth of drug-resistant bacteria. The new drug, called engineered cationic antimicrobial peptides (eCAPs), inhibited growth in about 90% of test bacterial strains.

Prenatal exposure to common household chemicals linked with substantial drop in child IQ

A recent study published in PLOS ONE found a significant link between prenatal exposure to di-n-butyl phthalate (DnBP) and di-isobutyl phthalate (DiBP) and substantial drops in child IQ scores. Children exposed during pregnancy to these chemicals had IQ scores on average six points lower than those exposed at lower levels.

Defects are perfect in laser-induced graphene

The study finds that laser-induced graphene (LIG) has a unique structure with five- and seven-atom rings, which can store charges and make it suitable for supercapacitors. Researchers developed a scalable one-step process to create LIG in detailed patterns.

Limiting internet congestion a key factor in net neutrality debate

A study published in the RAND Journal of Economics found that price discrimination by ISPs can lead to increased web congestion, as consumers adjust their behavior to take advantage of faster services. The researchers argue that relaxing net neutrality rules would ultimately benefit ISPs at the expense of consumers.

Crowdfunding 101

A study by USCB researchers determined that building an audience and engaging it during crowdfunding is crucial for success. The most important networks were those that were scalable, such as Twitter and email, which helped bring people to the projects.

How to achieve health equity

The article highlights the persistent health gap between whites and blacks, despite improvements in care access. Effective strategies for closing this gap include reporting clinical performance data by race, offering tailored interventions, and creating risk-adjusted scores.

Oldest horned dinosaur species in North America found in Montana

Researchers have identified the first definite horned dinosaur species from the Early Cretaceous period in North America, known as Aquilops americanus. This discovery sheds light on the biogeography of neoceratopsian dinosaurs and suggests a late Early Cretaceous intercontinental migratory event between Asia and North America.

Worms' mental GPS helps them find food

Scientists have developed a mathematical theory based on roundworm foraging that predicts how animals decide to switch from localized to very broad searching. The theory could explain animal behavior in a more unified way, including attention deficit hyperactivity disorder (ADHD) and extraterrestrial behavior.

As in a cloud

Physicists at Goethe University Frankfurt have used the COLTRIMS reaction microscope to demonstrate that the structure of the helium-3 molecule is a 'cloud' rather than a solid structure. The results resolve a long-standing dispute in theoretical physics and show that all possible configurations are equally probable.

Can poor sleep lead to dementia?

A new study published in Neurology found that people with sleep apnea or reduced deep sleep are more likely to have brain abnormalities associated with dementia. The study also discovered that those who spent less time in slow wave sleep had loss of brain cells, a risk factor for Alzheimer's disease.
