The night shift may lead to family nightmares

A study of over 4,000 dual-earner households with children aged 2-11 found that non-standard work schedules can negatively impact family functioning and child well-being. The effects were particularly strong for preschool-aged children, highlighting a challenge to the assumption that non-standard work is 'family friendly'.

Paleontologists learn how not to become a fossil

Researchers found that small body size and parasitic lifestyles hinder fossilization, while burrowing clams have a higher chance of becoming fossils. The study provides strategies for improving the reliability of the fossil record, enabling scientists to better understand biological dynamics.

How odors are sensed: A complex system clarified

A comprehensive study published in Cell reveals that inhibitory responses are widespread among odor receptors, and most receptors are inhibited by at least one odor. The research also shows that individual receptors range along a continuum from narrowly tuned to broadly tuned to odorants.

'Indirect damage' from 9/11

Following 9/11, American consumers reduced air travel by 12-20% and increased highway travel, leading to a substantial increase in miles-driven and traffic deaths. This behavioral change is attributed to strong emotional forces like fear and anxiety, highlighting the potential for indirect damage from terrorism.

Lion mane linked to climate

A study of zoo lions across the US found that cold temperatures contribute significantly to mane length and density, with up to half of the variation attributed to temperature. The research suggests that lion manes may not be as genetically determined as previously thought.

Gases in one dimension -- not your typical desk toy

Researchers at Penn State have developed a one-dimensional gas system that exhibits remarkable stability despite collisions among atoms. The system, dubbed the 'Quantum Newton's Cradle,' has been observed to maintain its momentum profile unchanged even after thousands of collisions.

SNM issues first procedure guideline for imaging cancer in adults and children with PET/CT

The Society of Nuclear Medicine and Molecular Imaging (SNM) has released a landmark procedure guideline for tumor imaging with 18F-FDG PET/CT. The document provides recommendations for patient preparation, image acquisition, interpretation criteria, and quality control to ensure high-quality imaging results.

Pacific Northwest tectonic plates are moving

Researchers suggest that the subduction of the northern portion of the Juan de Fuca plate beneath the North American plate may be slowing and eventually cease, potentially altering the seismic hazard profile of the region. The discovery was made using advanced technology and data from formerly classified U.S. Navy hydrophones.

Lunar rocks suggest meteorite shower

A recent study published in Geochimica et Cosmochimica Acta suggests a massive meteorite shower occurred on the Moon 3.8-4 billion years ago, potentially impacting Earth as well. The lunar rocks analyzed produced ages close to 3.9 billion years and exhibited different chemical fingerprints, indicating repeated bombardment by meteorites.

Woods Hole Research Center scientists create satellite map to show Chesapeake Bay urban development

Scientists at the Woods Hole Research Center have developed high-resolution maps of the built environment for the Chesapeake Bay watershed, capturing impervious surface cover and its implications for biogeochemical and hydrological processes. The new maps are being used to assess water quality and inform restoration efforts in the region.

Targeted drug delivery now possible with 'pHLIP' peptide

The pHLIP peptide accumulates in cell membranes at low pH and translocates molecules into cells without relying on traditional entry pathways. This technology has potential applications in imaging, diagnosis, and treatment of diseases associated with acidic environments.

Why and when we lie

A study using social comparison theory found that individuals are more likely to lie to those they know, particularly when their public image is threatened. This behavior is driven by a desire to protect one's self-image and self-worth, rather than purely strategic reasons.
