The affordability of healthy food is often cited as a barrier to low-income families eating nutritious meals. A new study published in the Journal of Nutrition Education and Behavior found that with menu planning and access to stores selling items in bulk, the average daily cost for serving healthy meals to a family of four…
A mass sacrifice at a 15th century archaeological site in Peru saw the ritual killing of over 140 children and over 200 llamas, according to a study released March 6, 2019 in the open access journal PLOS ONE by Gabriel Prieto of the National University of Trujillo, Peru and colleagues. This is the largest known…
Physicists from the University of Sheffield have discovered that when two atomically thin graphene-like materials are placed on top of each other their properties change, and a material with novel hybrid properties emerges, paving the way for design of new materials and nano-devices. This happens without physically mixing the two atomic layers, nor through a…
A diet containing compounds found in green tea and carrots reversed Alzheimer’s-like symptoms in mice genetically programmed to develop the disease, USC researchers say. Researchers emphasize that the study, recently published in the Journal of Biological Chemistry, was in mice, and many mouse discoveries never translate into human treatments. Nevertheless, the findings lend credence to…
Researchers from Jülich, Switzerland, France, the Netherlands, and the UK have discovered specific activity patterns in the brains of people with autism. These consistent patterns of functional connectivity might be used in the long term as therapeutic biomarkers. The idea behind this is that in future, doctors would be able to investigate whether certain treatments…
Physicists have used a seven-qubit quantum computer to simulate the scrambling of information inside a black hole, heralding a future in which entangled quantum bits might be used to probe the mysterious interiors of these bizarre objects. Scrambling is what happens when matter disappears inside a black hole. The information attached to that matter —…
Some wetlands perform better under pressure. A new study revealed that when faced with sea-level rise, coastal wetlands respond by burying even more carbon in their soils. Coastal wetlands, which include marshes, mangroves and seagrasses, already store carbon more efficiently than any other natural ecosystem, including forests. The latest study, published March 7 in the…
Scientists at Aarhus University in Denmark studying the effects of climate change on weather-dependent electricity systems have found a silver lining in Earth’s otherwise fraught future outlook. Temperatures may climb and seas may rise, but the lights (and, undoubtedly, the air conditioning) will still be on in nations with high capacities for wind and solar…
“They eat and sleep while they are airborne. This is something that researchers have believed since the 1950s, and now we can show that it’s true,” says Anders Hedenström, professor at the Department of Biology at Lund University. Three years ago, the same research team at Lund University observed that within the species common swift,…
Many raw meat dog food products contain high levels of bacteria that pose potential health risks to both animals and people, finds research published online in Vet Record. This is a particular issue for infants, the elderly, and those with poor immunity, warn the researchers. A raw meat-based diet has become increasingly popular for dogs…
