Bedtime battles: 1 in 4 parents say their child can't go to sleep because they're worried or anxious
One in four parents describe getting their young child to bed as difficult -- and these parents are less likely to have a bedtime routine, more likely to leave on a video or TV show, and more likely to stay with their child until they're asleep.
Direct evidence found for dairy consumption in the Pyrenees in the earliest stages of the Neolithic
A study on the remains of the Chaves and Puyascada caves, both located in the province of Huesca, Spain, yields the first direct proof of the consumption and processing of dairy products in the Pyrenees already at the start of the Neolithic period, approximately 7,500 years ago, as well as the consumption of pig. The results lead to doubts about the belief that these products were first used much later in the Pyrenean mountain range.
A high-fat diet may fuel anxiety
New research shows when animals are fed a diet high in saturated fat for nine weeks, their gut bacteria change in ways that influence brain chemicals and fuel anxiety.

Wear it, then recycle: Designers make dissolvable textiles from gelatin
Researchers hope their DIY machine will help designers around the world experiment with making their own, sustainable fashion and other textiles from a range of natural ingredients -- maybe even the chitin in crab shells or agar-agar from algae.
Ancient polar sea reptile fossil is oldest ever found in Southern Hemisphere
An international team of scientists has identified the oldest fossil of a sea-going reptile from the Southern Hemisphere -- a nothosaur vertebra found on New Zealand's South Island. 246 million years ago, at the beginning of the Age of Dinosaurs, New Zealand was located on the southern polar coast of a vast super-ocean called Panthalassa. 'The nothosaur found in New Zealand is over 40 million years older than the previously oldest known sauropterygian fossils from the Southern Hemisphere.
A new way to measure aging and disease risk with the protein aggregation clock
Could measuring protein clumps in our cells be a new way to find out our risk of getting age-related diseases? Researchers propose the concept of a 'protein aggregation clock' to measure aging and health.
Early diagnosis of hepatocellular carcinoma (HCC) -- one of the most fatal malignancies -- is crucial to improve patient survival. In a breakthrough study investigators report on the development of a serum fusion-gene machine-learning model. This important screening tool may increase the five-year survival rate of patients with HCC from 20% to 90% because of its improved accuracy in early diagnosis of HCC and monitoring the impact of treatment.
Pair of merging quasars at cosmic dawn
With the help of the powerful GNIRS instrument on the Gemini North telescope, one half of the International Gemini Observatory, supported in part by the U.S. National Science Foundation and operated by NSF NOIRLab, a team of astronomers have discovered a double-record-breaking pair of quasars. Not only are they the most distant pair of merging quasars ever found, but also the only pair confirmed in the bygone era of the Universe's earliest formation.
Extended maternal care central factor to human other animal, longevity
The relationship between mother and child may offer clues to the mystery of why humans live longer than expected for their size -- and shed new light on what it means to be human -- according to a new study.
Investigating the origins of the crab nebula
A team of scientists used NASA's James Webb Space Telescope to parse the composition of the Crab Nebula, a supernova remnant located 6,500 light-years away in the constellation Taurus.
