Deer and elk can help young Douglas-fir trees under some conditions
The deep age predictors can help advance aging research by establishing causal relationships in nonlinear systems.Deep aging clocks can be used for identification of novel therapeutic targets, evaluating the efficacy of various interventions, data quality control, data economics, prediction of health trajectories, mortality, and many other applications.
Depression affects one-third of lung cancer patients
Long considered pests by forest managers, deer and elk can help Douglas-fir seedlings thrive under certain vegetation management conditions, a five-year study shows.
Differences in replacement level fertility point to inequalities
About one-third of patients newly diagnosed with the most common form of lung cancer have moderate to severe symptoms of depression, a new study suggests. For many of these patients -- particularly those with severe symptoms -- depression occurs in a toxic blend of high levels of anxiety, traumatic stress, impaired day-to-day functioning and significant pain and other physical symptoms, findings showed.
District-level, real-time crime centers can help police cut crime levels
The percentage of the world's population that is above or below the 'replacement level of fertility' has long been used as a measure of demographic development. A new study revisited how this metric is calculated and how useful it really is in terms of informing policy decisions.
Does weight loss surgery affect colorectal cancer risk?
Police commanders often make decisions largely ad-hoc, based on whatever they hear about. A new study about a Chicago program finds that district-level police crime centers that use technology such as remote cameras and analytic tools to aid commanders creates decision making that is more data-driven and helps to reduce crime.
Drug decreases gut leakiness associated with ulcerative colitis
Although colorectal cancer is associated with obesity, it is unclear if weight loss surgery impacts the incidence of these tumors. Results from a new study published in the International Journal of Cancer suggest that the risk of colon cancer may be increased in individuals who have undergone such surgery.
Exposure to smoking in early childhood linked to hyperactivity and conduct problems
A research team led by biomedical scientists at the University of California, Riverside, has found that a drug approved by the FDA to treat rheumatoid arthritis and ulcerative colitis can repair permeability defects in the gut's epithelium.
Finnish children's motor skills at the top in Europe
In a recent study published in Journal of Child Psychology and Psychiatry, children exposed to smoking in the first four years of life were more likely to exhibit symptoms of hyperactivity and conduct problems.
First experimental genetic evidence of the human self-domestication hypothesis
Data gathered in Finland, Belgium and Portugal reveal that Finnish children are ahead of their European peers in motor skills at ages 6 to 10 years. Differences in motor skills increase with age and independently of the remarkable differences in overweight across the countries.
First giant planet around white dwarf found
A new University of Barcelona study reveals the first empirical genetic evidence of human self-domestication, a hypothesis that humans have evolved friendlier and more cooperative by selecting their companions depending on their behaviour. Researchers identified a genetic network involved in the unique evolutionary trajectory of the modern human face and prosociality, which is absent in the Neanderthals genome. The experiment is based on Williams Syndrome cells, a rare disease.
Freeze frame: Scientists capture atomic-scale snapshots of artificial proteins
Researchers using ESO's Very Large Telescope have, for the first time, found evidence of a giant planet associated with a white dwarf star. The planet orbits the hot white dwarf, the remnant of a sun-like star, at close range, causing its atmosphere to be stripped away and form a disc of gas around the star. This unique system hints at what our own solar system might look like in the distant future.
Genetic screen in worms reveals critical step in insulin synthesis
Scientists at Berkeley Lab are the first to use cryo-EM (cryogenic electron microscopy), a Nobel Prize-winning technique originally designed to image proteins in solution, to image atomic changes in a synthetic soft material. Their findings have implications for the synthesis of 2D materials for a wide variety of applications.
Getting to the 'art' of dementia: UC researchers highlight benefits of art intervention
The identification of a protein important for insulin synthesis may hold clues for understanding the pathogenesis of diabetes.Although the protein, called TRAP-alpha, was first discovered more than 30 years ago, its biological function has been unclear. The new findings, reported Dec. 4 in Science Advances, demonstrate that TRAP-alpha is required for both early and late steps in insulin synthesis.
Health care in baboons
University of Canberra researchers have shown that art gallery programs can improve the wellbeing of people living with dementia -- and they've backed it up by testing study participants' saliva.
How race is associated with differences among patients with hypertrophic cardiomyopathy
Sexually transmitted diseases reduce the willingness of female baboons to mate.
How small is a small-world network?
Researchers in this observational study looked at how race was associated with difference in symptoms, access to care, genetic testing and clinical outcomes among 2,467 patients (8.3% black and 91.7% white) with hypertrophic cardiomyopathy, a condition where the heart muscle becomes abnormally thick, which can make it harder to pump blood.
How tiny enzymes reign supreme in worldwide carbon recycling
This is the subject of a study published on 14 November in Nature Physics Communications by Gorka Zamora-LÃ³pez, a researcher at the Center for Brain and Cognition (CBC), and Romain Brasselet, a researcher at the International School for Advanced Studies (SISSA) in Trieste (Italy).
How to boost sales of fair trade and sustainable goods
That white rot fungi on fallen logs in a forest, it's super important.
Hundreds of environmental health professionals in US report challenges, research needs
When consumers are given responsibility for whether a product is produced, a stronger link develops between consumers and production that leads to anticipated feelings of guilt or gratification depending on the ethicality of the production process, which then influences purchase intentions.
Immigrants who naturalize outearn their peers
Hundreds of environmental health professionals across the nation report challenges and research needs in six areas -- drinking water, wastewater management, healthy homes, food safety, public health pests and emerging issues such as disaster risk reduction and new facility types for body art and cannabis-infused products.
Impact of lifestyle behaviors in early childhood on obesity
Looking at municipalities in Switzerland where citizenship applications were put to a popular vote, researchers identified immigrants who narrowly won or lost and tracked their earnings over the next several decades. After the vote, the winners began earning more, and the gap between the two groups widened over time. The earnings boost was about 5,637 CHF per year, on average, and was almost double among immigrants most likely to face discrimination in the job market.
Introducing peanuts and eggs early can prevent food allergies in high risk infants
Adhering to a healthy lifestyle at age 4 years is associated with a decreased risk of overweight, obesity, and abdominal obesity at 7 years, according to a study published in Pediatric Obesity.
Living at the edges
Research undertaken by King's College London and St George's, University of London has found that introducing certain foods early to infants can prevent them from developing an allergy despite low adherence to an introduction regime.
Looking at tropical forests through new eyes
The clustering of protected habitats in the Americas near international borders makes many iconic, wide-ranging animals physically dependent on good relations between neighboring countries and wildlife-friendly borders.
New University of Arizona-led science is using air-based maps of plant chemistry to improve carbon cycling models in hyperdiverse tropical forests.
