Depressed, inactive and out of work -- study reveals lives of lonely young adults
New research shows that lonely young adults are more likely to experience mental health problems and more likely to be out of work than their peers. The study gives a detailed snapshot of the lives of lonely 18-year-olds and shows how loneliness goes hand-in-hand with a wide range of problems in health and wellbeing.
Uncovering the secret law of the evolution of galaxy clusters
Using observational data from the Hubble Space Telescope and the Subaru Telescope, the size and mass of galaxy clusters have precisely been measured. The research team analyzed those data and found a simple law that regulates the growth of the clusters. They also showed that the clusters are still young and growing. The newfound law will serve as a tool to clarify the evolutionary history of clusters and the universe.
Stem cells from adults function just as well as those from embryos
A review of research on induced pluripotent stem cells (iPSCs) finds that donor age does not appear to influence their functionality. This validates iPSCs as a viable alternative to embryonic stem cells in regenerative medicine, and highlights the enormous potential of iPSCs derived from elderly patients to treat their age-related diseases.
Heart disease may only be a matter of time for those with healthy obesity
People who are 30 pounds or more overweight may want to slim down a bit even if they don't have high blood pressure or any other heart disease risk, according to scientists.
What can a tasty milkshake teach us about the genetics of heart disease?
Analysis of high-resolution genomic data in a large study population reveals novel low-frequency polymorphisms that drive response to dietary lipids and medication.
New model could help build communities of climate change-defying trees
Researchers in Australia have developed a model to help build plant communities that are more resilient to climate change.
Newspaper op-eds change minds
Researchers have found that op-ed pieces have large and long-lasting effects on people's views among both the general public and policy experts. The study also found that Democrats and Republicans altered their views in the direction of the op-ed piece in roughly equal measure.
Cognitive behavioral therapy can improve emotion regulation in children with autism
New research shows cognitive behavioral therapy (CBT) can help children with autism manage not only anxiety but other emotional challenges, such as sadness and anger. The study shows CBT can lead to significant improvements in children's emotional regulation. It also shows -- for the first time -- that CBT can improve more than just anxiety. This is the first transdiagnostic CBT trial for children with autism, employing a randomized controlled trial.
Milky Way's supermassive black hole may have 'unseen' siblings
Astronomers predict that galaxies with a mass similar to the Milky Way should host several supermassive black holes.
Future wearable device could tell how we power human movement
For athletes and weekend warriors alike, returning from a tendon injury too soon often ensures a trip right back to physical therapy. However, a new technology could one day help tell whether your tendons are ready for action.
Land use and pollution shift female-to-male ratios in snapping turtles
Current research shows that increasing global temperatures as a result of climate change are expected to produce more female turtles since their offspring are influenced by the nest's temperature. But now, a team of biologists has found that the nesting environment of turtles in agricultural habitats, which can ultimately lower nesting temperatures, can actually produce more males.
Leading genetics study method may need reconsideration, significant distortions discovered
Many conclusions drawn from a common approach to the study of human genetics could be distorted because of a previously overlooked phenomenon.
In Huntington's disease, heart problems reflect broader effects of abnormal protein
Researchers investigating a key signaling protein in Huntington's disease describe deleterious effects on heart function, going beyond the disease's devastating neurological impact. By adjusting protein levels affecting an important biological pathway, the researchers improved heart function in experimental animals, shedding light on the biology of this fatal disease.
High immune function tied to stunted growth
Elevated immune function during childhood results in as much as 49 percent growth reduction in Ecuador's indigenous Shuar population, researchers report.
How 'partner and rival' strategies can foster or destroy cooperation
A new study shows that in repeated interactions winning strategies are either partners or rivals, but only partners allow for cooperation.
What if you could know that your mild cognitive impairment wouldn't progress
Researchers found that, in some mild cognitive impairment patients, real neuropsychological stability over a decade is possible and that long-term stability could be predicted based on neuropsychological tests measuring memory and non-verbal abstract reasoning.
Deep water aquifer acts like natural bio-reactor, allowing microbes to consume carbon
Researchers have shown that underground aquifers along the mid-ocean ridge act like natural biological reactors, pulling in cold, oxygenated seawater, and allowing microbes to break down more -- perhaps much more -- refractory carbon than scientists ever believed.
Dark chocolate consumption reduces stress and inflammation
Findings from two new studies show dark chocolate consumption reduces stress and inflammation, while improving memory, immunity and mood.
Engineered Chinese shrub produces high levels of antimalarial compound
Artemisinin is a potent antimalarial compound produced naturally in low amounts by the Chinese shrub Artemisia annua, commonly known as sweet wormwood. Researchers in China now report a high-quality draft genome sequence of A. annua and their use of this information along with gene expression data to metabolically engineer plant lines that produce high levels of artemisinin.
Preconception zinc deficiency could spell bad news for fertility
The availability of micronutrients in the ovarian environment and their influence on the development, viability and quality of egg cells is the focus of a growing area of research. A new study shows that zinc deficiency can negatively affect the early stages of egg development, reducing the ability of the egg cells to divide and be fertilized. This may affect fertility months in the future. Researchers will present their results at the American Physiological Society annual meeting at Experimental Biology 2018 in San Diego.
